Meanwhile, the relay station R is a base station of the mobile phone communication network, and the second communication part 31a includes two communication means, a short range wireless communication and a mobile phone communication.
The data request part 32a outputs a data request signal to the data collection device 5a, the data request signal requesting the operation data retained in the collection data retention part 53a, under a certain condition such as an operation by an operator Ua carrying the mobile terminal 3a.
The data request signal outputted from the data request part 32a is sent to the data collection device 5a through the second communication part 31a.
The mobile terminal 3a having the above described configuration sends the operation data thorough the second communication part 31a to the server 2 being connected to a network N, the operation data being obtained from the collection data retention part 53a of the data collection device 5a.
The server 2 includes a collection data accumulation part 21, the collection data accumulation part 21 being configured to receive and accumulate the operation data sent from the mobile terminal 3a. The server 2 accumulates the operation data of the data collection device 5a to the collection data accumulation part 21. In addition, the server 2 also accumulates the operation data of the data collection device 5b to the collection data accumulation part 21. In this manner, the operation data of the tractors 4a and 4b are accumulated to the server 2, and thereby the operation data is analyzed and evaluated in the server 2.
Referring to
In the collection data retention part 53a, the operation data is accumulated in a form shown by the list, the list being shown by the arrowed line 90 in
The list shown by the arrowed line 90 in
Here, the operation data lastly accumulated in the collection data retention part 53a, that is, the collection data group 211 shows the hour meter indicating 13-plus hours, the vehicle speed indicating about 1.50 km/h, the revolution speed of PTO indicating about 320 rpm, and the fertilizer distribution amount indicating 0.08 to 0.09 kg.
As shown in the list shown by the arrowed line 91 in
Here, the operation data lastly accumulated in the collection data retention part 53b, that is, the collection data group 221 shows the hour meter indicating 98 to 99-plus hours, the vehicle speed indicating about 1.80 km/h, the revolution speed of PTO indicating about 350 rpm, and the fertilizer distribution amount indicating 0.04 to 0.05 kg, and accordingly has a trend different from that of the collection data group 211 of the collection data retention part 53a.
According to the data collection system 1 having the above described configuration, the operation data of the tractor 4a are surely saved in the collection data retention part 53a, and the operation data of the tractor 4b are surely saved in the collection data retention part 53b. Here, in a case where the data collection device 5b attached to the tractor 4b is detached and then is attached to the tractor 4a, the operation data of the tractor 4b and the operation data of the tractor 4a are mixed with each other, and thereby the management of the operation data becomes complex.
The collection data group 220 and the collection data group 221 each shown in
As shown in
In this manner, since the management of the operation data is complex in a case where the data collection devices 5a and 5b are attached to non-corresponding one of the tractors 4a and 4b, firstly in the present invention, the first identification information is retained on a side of the tractor 4a (4b), the second identification information is retained on a side of the data collection device 5a (5b), and then the check part 55a (55b) carries out the checking for both of the first identification information and the second identification information in collecting the data; thereby, it is judged whether the data collection device 5 is replaced. Then, when it is determined that the data collection device 5 has been replaced, that is, when the checking for both of the first identification information and the second identification information is unsuccessful, the data collection processing part 56a (56b) carries out the unsuccess process described as follows.
As described above, in a case where the data collection device 5a is attached to the tractor 4a, and in a case where the data collection device 5b is attached to the tractor 4b, the checking will be successful, and thus the unsuccess process is not carries out. On the other hand, in a case where the data collection device 5b is attached to the tractor 4a, and in a case where the data collection device 5a is attached to the tractor 4b, the checking will be unsuccessful, and thus the unsuccess process is carries out.
Next, exemplifying the case where the data collection device 5b is attached to the tractor 4a, the unsuccess process of the data collection device 5b (the data collection processing part 56b) will be explained, the unsuccess process being carried out when the checking for both of the first identification information and the second identification information is unsuccessful. Meanwhile, an operation of the unsuccess process of the data collection device 5a (the data collection processing part 56a) is approximately identical to that of the data collection device 5b (the data collection processing part 56b), and accordingly an explanation of the unsuccess process of the data collection device 5b (the data collection processing part 56b) will be omitted.
The unsuccess process carried out by the data collection processing part 56b includes a plurality of processes, a first process to a seventh process.
In a primary process (the first process), writing of the operation data to the collection data retention part 53b is forbidden to protect the operation data already retained. For example, the data collection processing part 56b forbids the collection data retention part 53b from writing the collection data group 230.
In a secondary process (the second process), the operation data already stored in the collection data retention part 53b (the operation data at the successful checking) is protected so as not to be lost by being overwritten. For example, the data collection processing part 56b protects the collection data groups 220 and 221 so that the operation data of the collection data groups 220 and 221 are not erased by overwriting of and saving of the collection data group 230 newly collected. For example, the data collection processing part 56b saves the collection data group 230 and the collection data groups 220 and 221 separately in the collection data retention part 53b, and disenables the data regions of the collection data groups 220 and 221 to be overwritten.
In a tertiary process (the third process), the data already stored in the collection data retention part 53b (the operation data at the successful checking) is outputted to an outside such as the server 3 and the mobile terminals 3a and 3b to evacuate the operation data already stored. For example, the data collection processing part 56b sends the operation data of the collection data groups 220 and 221 to the server 2 and the mobile terminals 3a and 3b, the operation data being already stored in the collection data retention part 53b. At that time, the data collection device 5b sends the first identification information (the agricultural machine identification information 61b) of the tractor 4b or the second identification information of the data collection device 5b together with the collection data groups 220 and 221, the data collection device 5b being attached to the tractor 4b, and thus the server 2 can recognize that the collection data groups 220 and 221 corresponding to the tractor 4b or the data collection device 5b.
In a quaternary process (the fourth process), the collecting of the operation data by the data collection device 5b is stopped after the checking for both the first identification information and the second identification information is unsuccessful. For example, the data collection processing part 56b does not carry out the collecting of the collection data group 230 after the checking for both the first identification information and the second identification information is unsuccessful.
In a quinary process (the fifth process), the data collection device 5b continues to collect the operation data after the checking for both the first identification information and the second identification information is unsuccessful; and additionally the result of the checking for both of the first identification information and the second identification information is related to the operation data, and the operation data and the result of the checking are retained in the collection data retention part 53b. For example, the data collection processing part 56b adds an unsucess flag F to the collection data group 230 collected after the checking is unsuccessful, the unsucess flag F indicating that the checking for both the first identification information and the second identification information is unsuccessful, and saves the unsuccess flag F and the collection data group 230 to the collection data retention part 53b.
In a senary process (the sixth process), the outsides such as the server 2 and the mobile terminals 3a and 3b are notified of the unsucess of the checking for both of the first identification information and the second identification information. For example, when the checking for both the first identification information and the second identification information is unsuccessful, the data collection processing part 56b sends the unsuccessful checking to the mobile terminal 3b, and displays the unsuccessful checking on the mobile terminal 3b. On the basis of the notification, the data already retained in the collection data retention part 53b can be surely protected in a manner, for example, disconnecting the data collection device 5b from the control device 6b, or stopping the operation of the data collection device 5b.
In a septenary process (the seventh process), the hour meter of the data collection device 5b is stopped. For example, as shown in
Meanwhile, the data collection processing part 56b carries out any one of the first process to the seventh process described above at the unsuccess process; however, the data collection processing part 56b may carry out the first process to the seventh process in combination.
For example, the data collection processing part 56b may carry out: the first process for forbidding to write the operation data to the collection data retention part 53b after the checking becomes unsuccessful; and the third process for outputting the operation data to the outside such as the server 3 and the mobile terminals 3a and 3b, the operation data being saved in the collection data retention part 53b before the checking becomes unsuccessful. In addition, the data collection processing part 56b may carry out: the second process for disenabling to overwrite the operation data, the operation data being collected before the checking becomes unsuccessful; and the sixth process to notify the server 2 and the like of the unsucess of the checking for both of the first identification information and the second identification information. In addition, the data collection processing part 56b may carry out: the second process; and the third process for stopping the collection of the operation data.
Meanwhile, in order to notify the outside of the unsucess of the checking for both of the first identification information and the second identification information, a method described below may be employed, the method including: disposing a display part (not shown in the drawings) on the data collection device 5a, the display part being constituted of LEDs (Light emitting devices) and the like; and lighting the display part. When the display part is disposed on the data collection device 5a, it can be known just beside the data collection device 5a that the checking for both of the first identification information and the second identification information is unsuccessful, and thereby rapidly promote to carry out the process for protecting the data already stored in the collection data retention part 53a.
As described above, summarizing the operations of the control device 6, the data collection device 5, and the like in the first embodiment, the operations are shown in
In response to the request from the check part 55a (55b), the control device 6a (6b) outputs the agricultural machine identification information 61a (61b) to the data collection device 5a (5b) (S110).
The check part 55a (55b) obtains the agricultural machine identification information 61a (61b) (S120). The check part 55a (55b) obtains the second identification information from the identification information retention part 51a (51b), and compares (checks) the agricultural machine identification information 61a (61b) with the second identification information, the agricultural machine identification information 61a (61b) being obtained from the control device 6a (6b) at the step S120 (S130). In a case where the checking for both of the first identification information and the second identification information becomes successful after the check part 55a (55b) checks the first identification information and the second identification information with each other (success at S140), the data collection processing part 56b starts collecting the operation data (S160), and carries out the unsuccess process described above when the checking for both of the first identification information and the second identification information is unsuccessful (unsuccess at S140) (S150).
The collection data retention part 53a (53b) adds the hour meter on the collected operation data and retains the operation data and the hour meter (S170). When the data request part 32a (32b) of the mobile terminal 3a (3b) requests sending of the collected operation data from the data collection device 5a (5b) (S180), the data collection device 5a (5b) outputs the operation data to the mobile terminal 3a (3b) in response to the request from the data request part 32a (32b), the operation data being retained in the collection data retention part 53a (53b) (S190).
The mobile terminal 3a (3b) receives the operation data outputted from the data collection device 5a (5b), and sends the received operation data to the server 2. The server 2 receives the operation data from the mobile terminal 3a (3b), and accumulates the received operation data to the collection data accumulation part 21 (S200).
In a second embodiment, as shown in
Meanwhile, the control device 6b of the agricultural machine 4b also includes: a check part 55d; and the data collection processing part 56d configured to carry out a process for data collection on the basis of a result of the checking by the check part 55d; however, the check part 55d has a configuration approximately identical to the check part 55c, the data collection processing part 56d has a configuration approximately identical to the data collection processing part 56c, and accordingly explanations of the check part 55d and the data collection processing part 56d will be omitted. In addition, in the second embodiment, configurations different from the configurations of the first embodiment will be explained.
The check part 55c checks the agricultural machine identification information 61a and the second identification information with each other, the agricultural machine identification information 61a being the first identification information retained in the control device 6a of the tractor 4a, the second identification information being retained in the identification information retention part 51a. In particular, the check part 55c obtains the second identification information from the data collection device 5a, and checks (compares) the agricultural machine identification information 61a and the second identification information with each other, the agricultural machine identification information 61a being the first identification information stored in the control device 6a. According to the comparison, it can be judged whether the second identification information corresponds to the agricultural machine identification information 61a, for example, whether the second identification information is related to the agricultural machine identification information 61a, or whether the second identification information corresponds to the agricultural machine identification information 61a.
When the checking for both of the first identification information and the second identification information is successful, the data collection processing part 56c orders the data collection device 5a to start to collect the operation data flowing in the vehicle communication network as a process relating to the collection of data. The data collection device 5a starts to collect the operation data in accordance with the order to start the collection from the data collection processing part 56c. On the other hand, when the checking for both of the first identification information and the second identification information is unsuccessful, the data collection processing part 56c carries out the process in unsuccessful check (an unsuccess process) described below.
Next, exemplifying a case where the data collection device 5b is attached to the tractor 4a as with the first embodiment, the unsuccess process of the control device 6a (the data collection processing part 56c) will be explained, the unsuccess process being carried out when the checking for both of the first identification information and the second identification information is unsuccessful. Meanwhile, an operation of the unsuccess process of the control device 6b (the data collection processing part 56d) is approximately identical to the operation of the unsuccess process of the control device 6a (the data collection processing part 56c), and an explanation of the operation will be omitted.
The unsuccess process carried out by the data collection processing part 56c includes a plurality of processes, a first process to a sixth process.
In a primary process (the first process), an order is outputted to the data collection device 5b, the order ordering to forbid to write the operation data to the collection data retention part 53b. In this manner, the data collection device 5b, for example, is forbidden from writing the collection data group 230 shown in
In a secondary process (the second process), an order is outputted to the data collection device 5b, the order ordering to protect the operation data already stored in the collection data retention part 53b (the operation data at the successful checking) so as not to be lost by being overwritten. In this manner, the data collection processing part 56b saves the collection data group 230 and the collection data groups 220 and 221 separately in the collection data retention part 53b, and disenables the data regions of the collection data groups 220 and 221 to be overwritten, thereby protecting the collection data groups 220 and 221 so that the operation data of the collection data groups 220 and 221 are not erased by overwriting of and saving of the collection data group 230 newly collected.
In a tertiary process (the third process), an order is outputted to the data collection device 5b, the order ordering to output the data already stored in the collection data retention part 53b (the operation data at the successful checking) to an outside such as the server 3 and the mobile terminals 3a and 3b. In this manner, the data collection device 5b sends the operation data of the collection data groups 220 and 221 to the server 2 and the mobile terminals 3a and 3b, the operation data being already stored in the collection data retention part 53b.
In a quaternary process (the fourth process), an order is outputted to the data collection device 5b, the order ordering to stop the collecting of the operation data by the data collection device 5b after the checking for both the first identification information and the second identification information is unsuccessful. In this manner, the data collection device 5b does not carry out the collecting of the collection data group 230 after the checking for both the first identification information and the second identification information is unsuccessful.
In a quinary process (the fifth process), an order is outputted to the data collection device 5b, the order ordering to relate the result of the checking for both of the first identification information and the second identification information to the operation data, and saving the operation data and the result of the checking in the collection data retention part 53b. In response to that, the data collection device 5b adds an unsucess flag F to the collection data group 230 collected after the checking is unsuccessful, the unsucess flag F indicating that the checking for both the first identification information and the second identification information is unsuccessful, and saves the unsuccess flag F and the collection data group 230 to the collection data retention part 53b.
Additionally, in a senary process (the sixth process), an order is outputted to the data collection device 5b, the order ordering to stop the hour meter of the data collection device 5b. In this manner, as shown in
Meanwhile, the control device 6a (the data collection processing part 56c) carries out any one of the first process to the sixth process described above at the unsuccess process; however, the control device 6a may carry out the first process to the sixth process in combination.
As described above, summarizing the operations of the control device 6, the data collection device 5, and the like in the second embodiment, the operations are shown in
In response to the request from the check part 55c (55d), the data collection device 5a (5b) outputs the second identification information to the control device 6a (6b) (S310).
The check part 55c (55d) obtains the second identification information (S320). The check part 55c (55d) compares (checks) the agricultural machine identification information 61a (61b) with the second identification information, the second identification information being obtained from the data collection device 5a (5b) at the step S320 (S330). In a case where the checking for both of the first identification information and the second identification information becomes successful (success at S340), the data collection processing part 56c (56d) outputs an order to the data collection device, the order ordering to start collecting the operation data (S360), and the data collection device 5a (5b) starts to collect the data (S370). The data collection processing part 56c (56d) carries out the unsuccess process described above when the checking for both of the first identification information and the second identification information is unsuccessful (unsuccess at S340) (S350).
The collection data retention part 53a (53b) adds the hour meter on the collected operation data and retains the operation data and the hour meter (S380). When the data request part 32a (32b) of the mobile terminal 3a (3b) requests sending of the collected operation data from the data collection device 5a (5b) (S390), the data collection device 5a (5b) outputs the operation data to the mobile terminal 3a (3b) in response to the request from the data request part 32a (32b), the operation data being retained in the collection data retention part 53a (53b) (S400).
The mobile terminal 3a (3b) receives the operation data outputted from the data collection device 5a (5b), and sends the received operation data to the server 2. The server 2 receives the operation data from the mobile terminal 3a (3b), and accumulates the received operation data to the collection data accumulation part 21 (S410).
Meanwhile, in the first embodiment and the second embodiment each described above. the mobile terminals 3a and 3b and the server 2 are capable of receiving the operation data sent from the data collection device 5; however, the mobile terminals 3a and 3b and the server 2 do not accept the operation data sent while the checking of the first identification information with the second identification information is unsuccessful (the operation data being collected by the data collection device 5 while the checking of the first identification information with the second identification information is unsuccessful). In particular, the mobile terminals 3a and 3b and the server 2 do not receive the operation data of the collection data group 230 among the collection data groups 220 and 221 and the collection data group 230 each shown in
Meanwhile, the mobile terminals 3a and 3b and the server 2 may carry out a process to erase the operation data sent while the checking of the first identification information with the second identification information is unsuccessful (the operation data being collected by the data collection device 5 while the checking of the first identification information with the second identification information is unsuccessful). For example, the mobile terminals 3a and 3b and the server 2 receive the collection data groups 220 and 221 and the collection data group 230 once, and automatically erase only the collection data group 230 after saving the operation data of the collection data groups 220 and 221 and of the collection data group 230.
As shown in
The data collection device 603 includes a communication part (an input-output part) 605 and a control part 606. The communication part 605 communicates with an outside in wireless, and carries out a communication in wireless, for example, in the Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series that is a communication standard. In particular, the communication part 605 converts the data received from the outside into a communication system of the data collection device 603 to output the data to the control part 606, and converts the data sent from the control part 606 into a communication system of the IEEE802.11 series to output the data to the outside. That is, the communication part 605 outputs the data (the signals) received from the outside to the control part 606, and sends, to the outside, the data (the signals) outputted from the control part 606.
The control part 606 is constituted of a CPU and the like, and carries out various types of processes relating to data outputted to the in-vehicle network N1. The control part 606, for example, obtains the parameter (the parameter value) in units of group (a unit collectively including the plurality of parameters), the parameter being outputted to the in-vehicle network N1, or obtains the parameter individually.
<Parameter Group (PG), and Obtaining the Parameter in Units of PG>
The obtaining of the parameter (the data) by the control part 606 will be explained below.
As shown in
In particular, as shown in
To be detailed, the parameter group is data defining a group mane, a communication speed, a data size, first identification information of the parameter group (PGN), a parameter name of the parameter belonging to the group, and the like, and is data determining, for each of the groups, the group name, the communication speed, the data size, the first identification information, the parameter name of the parameter belong to the group.
In this manner, referring to the parameter group, it can be judged which group does the parameter belong to. For example, as shown in
As shown in
A frame is sequentially inputted to the data collection device 603 in a broadcasting communication under a state where the working machine 602 operates, the frame having the parameters flowing in the in-vehicle network N1 (the frame preliminarily set in the in-vehicle network). The frame includes a plurality of the parameters belonging to a predetermined group, and includes the first identification information (the PGN) used for identifying the group.
Under a state where the frame is inputted to the data collection device 603, the obtaining part 611 monitors the PGN included in the frame. Here, the first obtaining part 611 obtains (receives) the frame when the frame is inputted to the data collection device 603, the frame including the PGN defined by the parameter group, the parameter group being stored in the definition storage part 610. That is, the first obtaining part 611 receives the frame when the PGN included in the frame is identical to the PGN of the parameter group.
For example, consider that three frames are inputted to the data collection device 603. At that time, in a case where the PGNs included in a first frame (1st frame) and a second frame (2nd frame) are not set to the parameter group stored in the definition storage part 610, the first obtaining part 611 does not receive the first frame and the second frame. On the other hand, in a case where the PGN included in a third frame (3rd frame) is preliminarily set to the parameter group, the first obtaining part 611 receives the third frame.
<Saving the Parameter in Units of PG>
Meanwhile, as shown in
As shown in
The group save condition includes a current state save condition and a log save condition (a history save condition), the current state save condition showing a condition to temporarily save the parameter group having been obtained (the group obtaining table), the log save condition showing a condition to save the save the parameter group having been obtained (the group obtaining table) for a long term.
To be detailed, the information storage part 612 includes: a RAM 612a constituted of a nonvolatile memory; and an EEPROM 612b constituted of a nonvolatile memory. The current state save condition is a condition to save the parameter group to the RAM 612a, and the log save condition is a condition to save the parameter group to the EEPROM 612b.
The current state save condition is a condition suitable to temporarily save the latest parameter group (save the parameter to the RAM 612a), and three conditions, “every n times of receiving”, “at changing of a particular par”, and “at changing of a PG unit”, are prepared as the current state save condition.
Here, the condition “every n times of receiving” shows that the parameter group (the group obtaining table) obtained by the first obtaining part 611 is saved to the RAM 612a every n times of receiving (obtaining) an identical parameter group (the group obtaining table of an identical PGN). In that case, the first obtaining part 611 counts the number of obtaining (the number of receiving) a predetermined parameter group (the group obtaining table of an identical PGN), and saves, to the RAM 612a, only the parameter group obtained n times. The number of the obtaining (the number of the receiving) is reset (to an initial value) every n times. Meanwhile, the first obtaining part 611 may save the parameter group to the RAM 612a when the number of the obtaining reaches a multiple of n.
The “at changing of a particular par” shows that the parameter group is saved to the RAM 612a only when the parameter (a target parameter) preliminarily set is changed in the parameter group (the group obtaining table) having been obtained. In that case, the first obtaining part 611 judges whether the parameter showing the “error existence” is changed from the parameter previously obtained, when the parameter “error existence” is determined as a target parameter, for example. Then, the first obtaining part 611 saves, to the RAM 612a, all of the parameters (for example, the error existence, the engine revolution speed, and the coolant temperature) of the group including the “error existence” when the parameter showing the “error existence” is changed.
The “at changing of a PG unit” shows that in a case where the parameter group is obtained, the parameter group (the group obtaining table) is saved when at least one of the parameters of the parameter group is changed in the parameter group having been obtained. In that case, the first obtaining part 611 judges whether any one of the parameters, the “error existence”, the “engine revolution speed”, and the coolant temperature, is changed from the parameters previously obtained, when the parameter “error existence” is determined as a target parameter, for example. Then, the first obtaining part 611 saves the parameter group (the group obtaining table) when at least one of the parameters, the “error existence”, the “engine revolution speed”, and the coolant temperature, is changed.
As described above, after obtaining the parameter group, the first obtaining part 611 saves the parameter group (the group obtaining table) having been obtained is saved to the RAM 612a when at least one of the save conditions, the “every n times of receiving”, the “at changing of a particular par”, and the “at changing of a PG unit”, is satisfied; however, the definition storage part 610 may save any one of the save conditions, the “every n times of receiving”, the “at changing of a particular par”, and the “at changing of a PG unit”, and additionally the first obtaining part 611 may carry out the saving of the parameter group (the group obtaining table). Meanwhile, the current state save condition is not limited to the example described above.
The log save condition is suitable for saving the parameters for a long term (saving the parameters to the EEPROM 612b), and three conditions, that is, “every n times of saving current value”, the “every t hours”, and the “at Key Off”, are prepared as the log save condition.
The “every n times of saving current value” shows that the parameter group (the group obtaining table) is saved to the EEPROM 612b every time when the parameter group (the group obtaining table) has been saved n times on the basis of the current state save condition (every time when the group obtaining table of an identical PGN has been saved n times to the RAM 612a). In that case, the first obtaining part 611 counts the number of saving a predetermined parameter group (the group obtaining table of an identical PGN) to the RAM 612a, reads, from the RAM 612a, only the parameter group (the group obtaining table) obtained at a timing when the number of saving reaches n, and saves the parameter group to the EEPROM 612b. The number of the saving is reset (to an initial value) when the number of saving a predetermined parameter group to the RAM 612a reaches n. Meanwhile, the first obtaining part 611 may save the parameter group to the EEPROM 612b when the number of the saving reaches a multiple of n.
The “every t hours” shows that the parameter group (the group obtaining table) obtained by the first obtaining part 611 is saved to the EEPROM 612b every time when t hours have passed. In that case, the first obtaining part 611 counts time by using a counter or the like, and saves the parameter group every time when t hours have passed after completion of the saving to the EEPROM 612b.
The “at Key Off” shows that the parameter group (the group obtaining table) obtained by the first obtaining part 611 is saved to the EEPROM 612b when an engine key (for example, an ignition key) for driving a power source (an engine or the like) is turned off, the power source being mounted on the working machine 602. In that case, the first obtaining part 611 monitors the ignition key in collecting the parameters; thus when the ignition key is turned on, the first obtaining part 611 does not save the parameter group (the group obtaining table) having been obtained, and when the ignition key is turned off, the first obtaining part 611 saves the parameter group to the EEPROM 612b.
As described above, after the parameter group is obtained, the first obtaining part 611 saves, to the EEPROM 612b, the parameter group (the group obtaining table) having been obtained, when any one of the save conditions, the “every n times of saving current value”, the “every t hours”, and the “at Key Off”, is satisfied; however, the definition storage part 610 may save any one of the save conditions, the “every n times of saving current value”, the “every t hours”, and the “at Key Off”, and additionally the first obtaining part 611 may carry out the saving of the parameter group (the group obtaining table). Meanwhile, the log save condition is not limited to the example described above.
As described above, the definition storage part 610 stores the group save conditions (for example, the current state save conditions and the log save conditions) under which the parameter group is saved to the information storage part 612 (for example, the RAM 612a and the EEPROM 612b), and the first obtaining part 611 saves the parameter group (the group obtaining table) to the information storage part 612 on the basis of the group save conditions; thereby, useless saving of the parameters is prevented, and the information storage part 612 is efficiently used.
<Obtaining the Parameter (Par) in Individual Units>
Then, as described above, the data collection device 603 obtains the parameters (the parameter values) in units of group; however, in addition to that, the data collection device 603 obtains the parameter also in individual units.
A process of obtaining the parameters in individual units is carried out by a second obtaining part 613 included in the control part 606. The second obtaining part 613 is constituted of a computer program or the like stored in the control part 606.
As shown in
The second obtaining part 613 relates the parameter showing an error existence to the second identification information (referred to as ParN) in the error obtaining table, the second identification information being used for identifying that the parameter is the “error existence”. Additionally, in the same manner, the second obtaining part 613 relates the parameter showing an engine revolution speed to the Par N also in the engine obtaining table, the Par N being used for identifying that the parameter is the “engine revolution speed”, and relates the parameter showing a coolant temperature to the Par N also in the coolant temperature obtaining table, the Par N being used for identifying that the parameter is the “coolant temperature”.
That is, the second obtaining part 613 is capable of sequentially and individually obtaining the parameters showing the “error existence” (the error obtaining table), sequentially obtaining the parameters showing the “engine revolution speed” (the engine obtaining table), and sequentially obtaining the parameters showing the “coolant temperature” (the coolant temperature obtaining table). To be summarized, the second obtaining part 613 is capable of obtaining the individual parameters by dividing the parameters in individual units, the parameters being obtained in units of the group obtained by the first obtaining part 611.
Hereinafter, the parameter in individual units is referred to as an individual parameter; the parameter showing the “error existence” is a first parameter, the parameter showing the “engine revolution speed” is a second parameter, and the parameter showing the “coolant temperature” is a third parameter, in the following explanations. Moreover, each of the error obtaining table, the engine obtaining table, and the coolant temperature obtaining table is referred to as an individual obtaining table in the following explanations.
<Saving the Parameter, the Par>
The individual parameter is saved to the information storage part 612. A process of saving the individual parameter to the information storage part 612 is also carried out on the basis of the save conditions preliminarily determined.
As shown in
As shown in
The current state save condition is a condition suitable to temporarily save the latest individual parameter (save the individual parameter to the RAM 612a), and two conditions, “every n times of receiving” and “at changing of a particular par”, are prepared as the current state save condition.
Here, the condition “every n times of receiving” shows that the individual parameter (the engine obtaining table) obtained by the second obtaining part 613 is saved to the RAM 612a every n times of receiving (obtaining) an identical individual parameter (the engine obtaining table).
In that case, the second obtaining part 613 counts the number of obtaining (the number of receiving) a predetermined individual parameter (the engine obtaining table), and saves, to the RAM 612a, only the individual parameter (the engine obtaining table) obtained n times. The number of the obtaining (the number of the receiving) is reset (to an initial value) every n times. Meanwhile, the second obtaining part 613 may save the individual parameter (the engine obtaining table) to the RAM 612a when the number of the obtaining reaches a multiple of n.
The “at changing of a particular par” shows that the individual parameter (the engine obtaining table) is saved to the RAM 612a only when the parameter (a target parameter) preliminarily set is changed in the individual parameter having been obtained. In that case, the second obtaining part 613 judges whether a second parameter showing the “engine revolution speed” is changed from the parameter previously obtained, when the second parameter “engine revolution speed” is determined as a target parameter, for example. Then, the second obtaining part 613 saves, to the RAM 612a, the second parameter, that is, the engine obtaining table when the second parameter is changed.
As described above, after obtaining the individual parameter (the engine obtaining table), the second obtaining part 613 saves the individual parameter (the engine obtaining table) having been obtained is saved to the RAM 612a when at least one of the save conditions, the “every n times of receiving” and the “at changing of a particular par” is satisfied; however, the definition storage part 610 may save any one of the save conditions, the “every n times of receiving” and the “at changing of a particular par”, and additionally the second obtaining part 613 may carry out the saving of the individual parameter (the engine obtaining table). Meanwhile, the current state save condition is not limited to the example described above. In addition, the log save condition is suitable for saving the individual parameter for a long term (saving to the EEPROM 612b), and three conditions, “every n times of saving current value”, the “every t hours”, and the “at Key Off”, are prepared as the log save condition.
The “every n times of saving current value” shows that the individual parameter (the engine obtaining table) is saved to the EEPROM 612b every time when the individual parameter has been saved n times on the basis of the current state save condition (every time when the engine obtaining table has been saved n times to the RAM 612a). In that case, the second obtaining part 613 counts the number of saving a predetermined individual parameter group (the engine obtaining table) to the RAM 612a, reads, from the RAM 612a, only the individual parameter (the engine obtaining table) obtained at a timing when the number of saving reaches n, and saves the individual parameter to the EEPROM 612b. The number of the saving is reset (to an initial value) when the number of the saving reaches n. Meanwhile, the second obtaining part 613 may save the individual parameter (the engine obtaining table) to the EEPROM 612b when the number of the saving reaches a multiple of n.
The “every t hours” shows that the individual parameter (the engine obtaining table) obtained by the second obtaining part 613 is saved to the EEPROM 612b every time when t hours have passed. In that case, the second obtaining part 613 counts time by using a counter or the like, and saves the individual parameter every time when t hours have passed after completion of the saving to the EEPROM 612b.
The “at Key Off” shows that the individual parameter obtained by the second obtaining part 613 is saved to the EEPROM 612b when the engine key (for example, the ignition key) for driving the power source (the engine or the like) is turned off, the power source being mounted on the working machine 602. In that case, the second obtaining part 613 monitors the ignition key in collecting the parameters; thus when the ignition key is turned on, the second obtaining part 613 does not save the individual parameter (the engine obtaining table) having been obtained, and when the ignition key is turned off, the second obtaining part 613 saves the individual parameter to the EEPROM 612b.
As described above, after the individual parameter (the engine obtaining table) is obtained, the second obtaining part 613 saves, to the EEPROM 612b, the individual parameter (the engine obtaining table) having been obtained, when any one of the save conditions, the “every n times of saving current value”, the “every t hours”, and the “at Key Off”, is satisfied; however, the definition storage part 610 may save any one of the save conditions, the “every n times of saving current value”, the “every t hours”, and the “at Key Off”, and additionally the second obtaining part 613 may carry out the saving of the individual parameter (the engine obtaining table). Meanwhile, the log save condition is not limited to the example described above.
In the above descried explanation of the individual save condition, the “engine obtaining table” is exemplified and explained, however, the “error obtaining table” and the “coolant temperature obtaining table” are also saved on the basis of the individual save condition.
As described above, the individual save conditions (for example, the current state save conditions and the log save conditions) under which the individual parameter is saved to the information storage part 612 (for example, the RAM 612a and the EEPROM 612b) are stored, and the second obtaining part 613 saves the individual parameter (the individual obtaining table) to the information storage part 612 on the basis of the individual save conditions; thereby, useless saving of the individual parameters (the individual obtaining table) is prevented, and the information storage part 612 is efficiently used.
<First Condition (the Individual Save Condition) of the Definition File>
Meanwhile, the individual save condition described above is shown in the definition file showing: information relating to the group obtaining table; and information relating to the individual obtaining table. The definition file is determined for each of the machine types of the working machines 602, and is stored in the definition storage part 610.
As shown in
The second obtaining part 613 firstly refers to the ParN corresponding to the individual parameter being to be saved, to the PGN of the group including the individual parameter, and to the definition file, in saving the individual parameter having been obtained, and the second obtaining part 613 extracts the individual save condition from the definition file. For example, as shown in
That is, the second obtaining part 613 extracts the individual save condition of the individual parameter on the basis of: the first identification information of the group to which the individual parameter belonged; the second identification information of the parameter corresponding to the individual parameter; and the definition file, and saves the individual parameter to the information storage part 612 on the basis of the individual save condition having been extracted. In particular, the second obtaining part 613 divides the parameters (the parameter group) into the individual parameters, the parameters (the parameter group) being obtained by the first obtaining part 611 in units of the group, and saves the individual parameter satisfying the save condition defined in the definition file from among the individual parameters having been divided.
<Outputting (Sending) the Parameter>
Then, the parameters saved in the RAM 612a and in the EEPROM 612b are outputted to an outside through the communication part (the input-output part) 605. In particular, the communication part (the input-output part) 605 sends the parameter to a mobile terminal 604 constituted of a smartphone (multifunctional mobile phone) or a mobile computer such as a tablet PC, which has a relatively high computing capability. The mobile terminal 604 carries out the wireless communication with the communication part 605 in the Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series that is a communication standard; for example, when the mobile terminal 604 requests the parameter, the communication part 605 reads, through the control part 606, the parameter group (the group obtaining table) and the individual parameters (the individual obtaining table) each saved in the EEPROM 612b, and sends the parameter having been read to the mobile terminal 604.
In addition, under a state where the wireless communication between the mobile terminal 604 and the communication part 605 is established, the communication part 605 reads the parameter group (the group obtaining table) and the individual parameters (the individual obtaining table) each saved in the RAM 612a, and sequentially sends the parameter to the mobile terminal 604. That is, the communication part 605 sends the parameter saved in the RAM 612a toward the mobile terminal 604 in a push sending manner.
As described above, the first obtaining part 611 and the second obtaining part 613 are capable of obtaining the parameters in units of group, the parameters belonging to the group, and also capable of obtaining the parameters in individual units.
For this reason, watching the parameters obtained in units of group, that is, the group obtaining table, it is possible to immediately know how the parameters are configured at a certain timing. For example, the parameter of the error existence, the parameter of the engine revolution speed, and the parameter of the coolant temperature are obtained as a group, and accordingly values of the engine revolution speed and the coolant temperature, especially the values at occurrence of the error, can be immediately known on the basis of the group obtaining table.
On the other hand, watching the parameters in individual units, that is, the individual obtaining table, change and trend of a predetermined parameter can be immediately known. For example, since the parameter of the engine revolution speed is obtained individually, the change of the engine revolution speed and the trend of the engine revolution speed for a predetermined period can be immediately known on the b basis of the engine obtaining table.
In addition, the first obtaining part 611 and the second obtaining part 613 are capable of saving, to the RAM 612a and the EEPROM 612b, the parameters obtained in units of group; and the parameters obtained in individual units, on the basis of the save conditions. Accordingly, though a large number of the parameters are outputted to the in-vehicle network for a short period, necessary parameters can be obtained at a necessary interval on the basis of the save conditions. For example, the information relating to the error is needed when the error occurs, and thus an interval of the saving is not required to be shorter than an interval of the saving of the engine revolution speed. On the other hand, since the engine revolution speed is needed during an operation of the working machine 602, the engine revolution speed is required to be saved frequently than the information relating to the error.
As described above, the parameters saved in the information storage part 612 (for example, the RAM 612a and the EEPROM 612b) are sent to the outside such as the mobile terminal 604 through the communication part 605, and thereby the mobile terminal 604 obtains the parameters of the working machine 602. And, a state of operations having been carried out by the working machine 602 can be analyzed by sorting the parameters obtained by the mobile terminal 604 and the like. In addition, the parameter of the operations having been carried out by the working machine 602 can be obtained as operation information on a side of the mobile terminal 604.
<Calculation Condition>
In the embodiment described above, the second obtaining part 613 obtains and saves the individual parameter (the individual obtaining table); however, it is preferred to calculate the individual parameter before the individual parameter is saved to the information storage part 612 (the RAM 612a and the EEPROM 612b) and then to save the calculation result to the information storage part 612. Next, a case of the calculation and the saving of the individual parameter (an modified example) will be explained.
The calculation of the individual parameter is carried out by a calculation part 614 disposed on the control part 606. The calculation part 614 is constituted of a computer program or the like stored in the control part 606. The calculation part 614 calculates the individual parameter on the basis of a calculation condition preliminarily determined.
Four conditions, that is, “accumulation”, “counting”, “statistics”, and “frequency”, are prepared as the calculation conditions. The “accumulation” shows calculation of a time length where an identical individual parameter (the individual obtaining table of an identical ParN) meets a value preliminarily specified (a specified value) in a predetermined time. The specified value is preliminarily determined for each of the individual parameters. For example, assume that the engine revolution speed “800 rpm” is set as the specified value. In that case, under a state where the second obtaining part 613 continuously obtains the parameter (the second parameter) showing the engine revolution speed, the calculation part 614 calculates the time length where the second parameter meets the “800 rpm” in a predetermined time.
The “counting” shows calculation of the number where an identical individual parameter (the individual obtaining table of an identical ParN) meets a value within a range preliminarily specified (a specified range) in a predetermined time. For example, a range “600 rpm to 800 rpm” (a first specified range), a range “801 rpm to 1000 rpm” (a second specified range”, a range “1001 rpm to 1500 rpm” (a third specified range), and a range “1501 rpm or more” (a fourth specified range) are set as the specified range of the engine revolution speed.
In that case, under a state where the second obtaining part 613 continuously obtains the second parameter (the engine revolution speed), the calculation part 614 calculates the number of meeting the first specified range in a predetermined time, the number of meeting the second specified range in a predetermined time, the number of meeting the third specified range in a predetermined time, and the number of meeting the fourth specified range in a predetermined time.
The “statistics” shows calculation of an average value, the maximum value, and the minimum value of an identical individual parameter (the individual obtaining table of an identical ParN). For example, under a state where the second obtaining part 613 continuously obtains the second parameter (the engine revolution speed), the calculation part 614 calculates an average value, the maximum value, and the minimum value of the engine revolution speed obtained in a predetermined time.
The “frequency” shows calculation of a time length where an identical individual parameter (the individual obtaining table of an identical ParN) meets a value within a range preliminarily specified (a specified range). For example, assume that a first specified range, a second specified range, a third specified range, and a fourth specified range are set as the specified range of the engine revolution speed, as in the “counting”. In that case, under a state where the second obtaining part 613 continuously obtains the parameter (the second parameter) showing the engine revolution speed, the calculation part 614 calculates a time length where the second parameter meets a value within the first specified range, a time length where the second parameter meets a value within the second specified range, a time length where the second parameter meets a value within the third specified range, and a time length where the second parameter meets a value within the fourth specified range. Meanwhile, it is preferred to stop the calculation when the second parameter has been out of the specified range preliminarily determined. For example, under a state where the calculation part 614 calculates, by using the second parameter, a time length satisfying the “801 rpm to 1000 rpm” (the second specified range), the calculation part 614 completes the calculation of the time length at a point of time when the second obtaining part 613 has obtained the second parameter (for example, 680 rpm) being out of the second specified range, the time length satisfying the second specified range.
Then, the individual parameters calculated under the calculation conditions, the “accumulation”, the “counting”, the “statistics”, and the “frequency” are sequentially saved to the RAM 612a after the completion of the calculation.
<Second Condition (the Calculation Condition) of the Definition File>
Meanwhile, the calculation condition described above is shown in the definition file.
As shown in
In calculating the individual parameter having been obtained, the second obtaining part 613 firstly refers to the ParN corresponding to the individual parameter being to be calculated, the PGN of the group to which the individual parameter belongs, and the definition file, and extracts the current state save condition and the calculation condition from the definition file. For example, as shown in
In addition, the second obtaining part 613 refers to the ParN, the PGN, and the definition file, extracts the log save condition, and stores the calculation result to the EEPROM 612b on the basis of the log save condition.
As described above, according to the calculation part 614 and the like, the calculation part 614 is capable of calculating the individual parameter on the basis of the calculation condition specified in the definition file, saving the calculation result of the individual parameter to the RAM 612a, the individual parameter being calculated by the calculation part 614, and saving the calculation result to the EEPROM 612b.
According to the data collection device 603 of the present invention, data (the parameters) flowing on the in-vehicle network N1 of the working machine 602 can be collected in units of group and in individual units, and further necessary data can be compacted and saved on the basis of the save condition and the calculation condition. The operation data relating to an agricultural operation can be easily obtained when the data collection device 603 is attached to a tractor, a combine, and a rice transplanter, for example.
For example, the parameters, a revolution speed of a rotary, a load of the rotary, an engine revolution speed, a vehicle speed, a depth of plowing, and the like are outputted to the in-vehicle network N1 in a case where a cultivator is coupled as an operation tool to a rear portion of the tractor, and then the tractor is operated. The first obtaining part 611 and the second obtaining part 613 are capable of obtaining the parameters (data), the revolution speed of the rotary, the load of the rotary, the engine revolution speed, the vehicle speed, the depth of plowing, and the like. Meanwhile, the revolution speed of the rotary, the load of the rotary, the engine revolution speed, the vehicle speed, the depth of plowing, and the like are detected by an electronic device (an electric component) 7 such as a sensor attached on the tractor and the cultivator.
Or, in a case where the operation tool coupled to the tractor is a fertilizer distributor, an agricultural chemicals distributor, and a seed distributor, the first obtaining part 611 and the second obtaining part 613 are capable of obtaining the parameters (data) such as the vehicle speed, the engine revolution speed, the distribution amounts (a fertilizer distribution amount, an agricultural chemicals distribution amount, and a seed distribution amount). Meanwhile, the distribution amounts (the fertilizer distribution amount, the agricultural chemicals distribution amount, and the seed distribution amount) are also detected by the electronic devices (the electric components) 7 attached on the tractor, the fertilizer distributor, the agricultural chemicals distributor, and the seed distributor.
In addition, in a case where the operation tool is a harvest machine, the data (the parameter) such as a vehicle speed, an engine revolution speed, a harvest amount are outputted to the in-vehicle network N1, and the vehicle speed, the engine revolution speed, and the harvest amount can be obtained. The harvest amount is also detected by the electronic devices (the electric components) 7 attached on the tractor and the harvest machine.
In this manner, the data collection device 603 is attached on the agricultural machine such as the tractor, and thereby obtaining, as the parameters, the revolution speed of the rotary, the load of the rotary, the engine speed, the vehicle speed, the depth of plowing, the distribution amounts, and the harvest amount.
Meanwhile, in the data collection device 603 described above, the definition storage part 610 saves the definition file including the parameter group, the save condition, the calculation condition, and the like in order to collect the data (the parameter) of the working machine 602; however, the definition file is written to the definition storage part 610 by a manufacturer at the manufacture of the working machine 602.
As shown in
As shown in
The computer 621 includes a plurality of the definition files configured of combinations of the PGN blocks A, the calculation blocks B, and the save blocks C each preliminarily prepared. When a machine type of the working machine 602 (a machine type of a working machine being to mount the data collection device 603) is chosen on a monitor of the computer 621, the computer 621 extracts the definition file having the PGN block A, the calculation block B, and the save block C each corresponding to the machine type having been chosen, and writes the definition file having been extracted to the data collection device 603 connected to the computer 621.
For example, in a case where the working machine 602 is a small-size tractor, the computer 621 extracts, from the plurality of definition files, a definition file (an arrowed line Q1) configured of the first PGN block A1, the third calculation block B3, and the second save block C2, and writes the definition file to the data collection device 603, the data collection device 603 being to be attached to the small-size tractor 2. In addition, in a case where the working machine 602 is a large-size tractor, the computer 621 chooses a definition file (an arrowed line Q2) configured of the first PGN block A1, the first calculation block B1, and second save block C3, and writes the definition file to the data collection device 603, the data collection device 603 being to be attached to the large-size tractor 2. In a case where the working machine 602 is a combine, the computer 621 extracts, from the plurality of definition files, a definition file (an arrowed line Q3) configured of the third PGN block A3, the second calculation block B2, and the third save block C3, and writes the definition file to the data collection device 603, the data collection device 603 being to be attached to the combine.
A tractor, a combine, a rice transplanter, and the like are employed as the working machine 602; however, as described above, output conditions of the parameters (for example, an output interval and a bit number of the parameter) outputted to the in-vehicle network N1 are different from each other in the small-size tractor and in the large-size tractor even when the small-size tractor and the large-size tractor are the same type of the working machine 602, that is, the tractor, and accordingly, the data (the parameter) after the calculation can be obtained in a similar form (configuration) by writing, to the data collection device 603, the definition files showing different calculation conditions for each of the machine types. In addition, output conditions of the parameters outputted to the in-vehicle network N1 may be different from each other in a tractor, in a combine, and in a rice transplanter even in agricultural machines, the same category; the definition file is arbitrarily changed corresponding to that, and thereby numerical values of the data collected by the data collection device 603 (the data after the calculation) are unified in a similar form between different machine types.
A fourth embodiment shows an modified examples of the writing system and of the data collection device 603 of the writing system. Configurations different from the configurations of the third embodiment will be explained.
As shown in
The data collection device 603 obtains various types of data outputted from the electronic device (the electric component), the electronic device being mounted on the working machine 602. The electronic device (the electric component) is a sensor, a switch, a CPU, an MPU, or the like as in the third embodiment; however, may be anything mounted on the working machine 602.
Meanwhile, in the third embodiment, the data collection device 603 obtains data through the in-vehicle network, the data being outputted to the in-vehicle network; however, the data collection device 603 according to the fourth embodiment may obtain the data through the in-vehicle network, and may directly obtain, from the electronic device, data outputted from the electronic device. That is, the data collection device 603 according to the embodiment is capable of being connected to the in-vehicle network of the working machine 602 or to the electronic device.
Additionally, in the third embodiment, the data is collected in units of group and in individual units by using a method (a first method) for obtaining the data (the parameter) in units of the data group (the parameter group) and dividing the data group (the parameters) into individual data (the individual parameter), the data group being obtained in units of group; however, in the fourth embodiment, not limited to the first method, a method for obtaining the data in units of group may be employed, and a method for obtaining the data in individual units may be employed, but the data collection may be carried out by using the first method shown in the third embodiment.
As shown in
The communication part 605 communicates with an outside in wireless, and carries out a communication in wireless, for example, in the Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series that is a communication standard. In particular, the communication part 605 converts the data received from the outside into a communication system of the data collection device 603 to output the data to the control part 606, and converts the data sent from the control part 606 into a communication system of the IEEE802.11 series to output the data to the outside. That is, the communication part 605 outputs the data (the signals) received from the outside to the control part 606, and sends, to the outside, the data (the signals) outputted from the control part 606.
The definition storage part 610 and the information storage part 612 are constituted of a nonvolatile memory, for example, an EEPROM. The definition storage part 610 stores a setting condition relating to the collection of data, and the information storage part 612 stores obtained data, a calculation result, and the like.
The control part 606 is constituted of a CPU and the like, and carries out various types of processes relating to data outputted to the electronic device or to the in-vehicle network N1. When the data inputted to the data collection device 603 is data being to be collected, the control part 606 receives the data having been inputted and stores the data to the information storage part 612, and carries out a calculation process by using the data having been inputted. The saving process of and the calculation process of the data are carried out on the basis of a setting condition stored in the definition storage part 610.
For example, when the data, for example, the error existence, the engine revolution speed, and the coolant temperature are inputted to the data collection device 603, the control part 606 sores, to the information storage part 612, the error existence, the engine revolution speed, and the coolant temperature on the basis of the setting condition. In addition, the control part 606 carries out the calculation on the basis of the setting condition by using the error existence, the engine revolution speed, the coolant temperature, and the like each having been obtained.
In addition, in a case where the data sent from an outside to the data collection device 603 is data for rewriting (for example, the definition file having the setting condition), the control part 60 rewrites the definition file stored in the definition storage part 610 when the communication part 605 or the like receives the data for rewriting.
Next, the setting condition will be explained in detail.
The setting condition relating to the collection of data is a condition (the save condition) relating to the data saving or is a condition (the calculation condition) relating to the data calculation. The save condition and the calculation condition are stored in the definition storage part 610 as the definition file.
As shown in
Here, the condition “every n times of receiving” shows that the data obtained by the control part 606 is saved to the information storage part 612 every n times when the control part 606 (the data collection device 603) receives the data. In that case, the control part 606 counts the number of obtaining (the number of receiving) a predetermined data (for example, the engine revolution speed), and saves, to the information storage part 612, only a predetermined data (for example, the engine revolution speed) obtained at appoint of time when the number of obtaining reaches n. The number of the obtaining (the number of the receiving) is reset (to an initial value) every n times. Meanwhile, the control part 606 may save, to the information storage part 612, obtained data at a point of time when the number of the obtaining reaches a multiple of n.
The condition “at changing” shows that the data is saved to the information storage part 612 only when the data is changed compared to data previously obtained. In that case, the control part 606 saves the engine revolution speed when the engine speed is changed, for example.
The “every t hours” shows that the data obtained by the control part 606 (the data collection device 603) is saved to the information storage part 612 every time when t hours have passed. In that case, the control part 606 counts time by using a counter or the like, and saves the data every time when t hours have passed after completion of the saving to the information storage part 612.
The “at Key Off” shows that the data obtained by the control part 606 (the data collection device 603) is saved to the information storage part 612 when an engine key (for example, an ignition key) for driving a power source (an engine or the like) is turned off, the power source being mounted on the working machine 602. In that case, the control part 606 monitors the ignition key in collecting the data; thus when the ignition key is turned on, the control part 606 does not save the data having been obtained, and when the ignition key is turned off, the control part 606 saves the data to the information storage part 612.
The four save conditions, that is, the “every n times of receiving”, the “at changing”, the “every t hours”, and the “at Key Off”, are shown; however, the save condition is not limited to the examples described above.
In addition, four conditions, that is, “accumulation”, “counting”, “statistics”, and “frequency”, are prepared as the calculation conditions in the definition file. Meanwhile, in the explanation of the calculation condition, the data of the engine revolution speed will be explained, for convenience in the explanation.
The “accumulation” shows calculation of a time length where a predetermined data meets a value preliminarily specified (a specified value) in a predetermined time. The specified value is preliminarily determined for each of the predetermined data. For example, assuming that the specified value “800 rpm” is set as the data of the engine revolution speed, the control part 606 calculates the time length where the second parameter meets the “800 rpm” in a predetermined time by using the engine speed having been obtained.
The “counting” shows calculation of the number where a predetermined data meets a value within a range preliminarily specified (a specified range) in a predetermined time. For example, a range “600 rpm to 800 rpm” (a first specified range), a range “801 rpm to 1000 rpm” (a second specified range”, a range “1001 rpm to 1500 rpm” (a third specified range), and a range “1501 rpm or more” (a fourth specified range) are set as the specified range of the engine revolution speed.
In that case, the control part 606 calculates the number of meeting the first specified range in a predetermined time, the number of meeting the second specified range in a predetermined time, the number of meeting the third specified range in a predetermined time, and the number of meeting the fourth specified range in a predetermined time by using the engine revolution speed having been obtained.
The “statistics” shows calculation of an average value, the maximum value, and the minimum value of a predetermined data. For example, the control part 606 calculates an average value, the maximum value, and the minimum value of the engine revolution speed obtained in a predetermined time by using the engine revolution speed having been obtained.
The “frequency” shows calculation of a time length where a predetermined data meets a value within a range preliminarily specified (a specified range). For example, assuming that a first specified range, a second specified range, a third specified range, and a fourth specified range are set as the specified range of the engine revolution speed, as in the “counting”. In that case, the control part 606 calculates a time length where the engine revolution speed meets a value within the first specified range, a time length where the engine revolution speed meets a value within the second specified range, a time length where the engine revolution speed meets a value within the third specified range, and a time length where the engine revolution speed meets a value within the fourth specified range. Meanwhile, it is preferred to stop the calculation when the second parameter has been out of the specified range preliminarily determined. For example, under a state where the control part 606 calculates a time length satisfying the “801 rpm to 1000 rpm” (the second specified range), the control part 606 completes the calculation of the time length at a point of time when the engine revolution speed having been obtained has been out of the second specified range, for example, 680 rpm, the time length satisfying the second specified range. In this manner, the calculation results calculated under the calculation conditions, the “accumulation”, the “counting”, the “statistics”, and the “frequency” are saved to the information storage part 612 after the completion of the calculation.
In particular, the identification information is set for each data, and the identification information and the conditions (the save condition and the calculation information) are related to each other, in the definition file. As shown in
Additionally, in the definition file, a number “12” is set as the identification information to the data of the “engine revolution speed”, the number “12” showing that the data is the “engine revolution speed”; the “every n times of receiving” is set as the save condition to the identification information of the “engine revolution speed”, and the “frequency” is set as the calculation condition.
Furthermore, in the definition file, a number “13” is set as the identification information to the data of the “coolant temperature”, the number “13” showing that the data is the “coolant temperature”; the “every t hours” is set as the save condition to the identification information of the “coolant temperature”, and the “statistics” is set as the calculation condition.
As described above, the save condition preliminarily set is related to the definition file for each of the identification information of data, and the calculation condition preliminarily set is also related to the definition file. Accordingly, when obtaining the data, the data collection device 603, that is, the control part 606 carries out the saving of and the calculating of obtained data to save the data to the information storage part 612 on the basis of the save condition and the calculation condition each related to the data.
Meanwhile, a relationship between the identification information of the data, the save condition, and the calculation condition, that is, the setting condition varies for each of the definition files; as shown in
Next, the definition files having different setting conditions will be explained in detail.
As shown in
A 2nd definition file (a second definition file) sets the calculation conditions identical to the calculation conditions of the first definition file, and sets not the save condition “every t hours” of the plurality of save conditions but the save condition “every n times of receiving” to the data “coolant temperature”.
A 3rd definition file (a third definition file) sets the save conditions identical to the save conditions of the first definition file, and sets not the calculation condition “frequency” of the plurality of calculation conditions but the calculation condition “statistics” to the data “engine revolution speed”.
As described above, the storage part 630 of the computer 621 stores the definition files each having different combinations of data types and the setting conditions (the save condition and the calculation condition).
The computer 621 carries out a process of writing the definition file to the data collection device 603 (the definition storage part 610), the definition file corresponding to a machine type of the working machine 602. That is, the storage part 630 of the computer 621 stores the plurality of definition files each having different setting conditions (the save condition and the calculation condition), and the computer 621 carries out a process of writing the definition file corresponding to a machine type of the working machine 602 to the data collection device 603, from among the plurality of definition files.
Next, the computer 621 will be explained in detail.
The computer 621 writes the definition file to the data collection device 603, and is constituted of a personal computer, for example. Meanwhile, the computer 621 may be constituted of a smart phone (a multifunctional mobile phone), a tablet computer, or the like.
The computer 621 is capable of communicating with the data collection device 603 in wired or in wireless. In particular, the computer 621 includes a communication part 634 configured to carry out a wireless communication. The communication part 634 carries out a wireless communication with the communication part 605 of the data collection device 603, that is, carries out a wireless communication in the Wi-Fi (Wireless Fidelity, registered trademark) of the IEEE802.11 series that is a communication standard, and is capable of sending the definition files and the like in wireless to the data collection device 603 (the communication part 605). Or, the computer 621 includes a communication part 635 configured to carry out a communication in wired. The communication part 635 carries out a data communication in wired with the communication part 605 of the data collection device 603, and is capable of sending the definition files and the like to the data collection device 603 (the communication part 605) by connecting the communication part 605 and the communication part 635 to each other with a cable. Meanwhile, in a case where the computer 621 is connected to the data collection device 603 by wire, the communication part 605 (an input-output part) of the data collection device 603 is configured as not only a device for wireless communication but also a device for connecting a LAN, a USB, an RS232C, and the like.
The computer 621 includes an extraction part 631 and a writing part 632. The extraction part 631 and the writing part 632 are constituted of a computer program and the like stored in the computer 621.
The extraction part 631 extracts the definition file corresponding to the working machine 602 from among the plurality of definition files stored in the storage part 630. In particular, the computer 621 is connected to the data collection device 603 in wired or in wireless, and the computer 621 firstly displays a machine type setting screen in writing the definition file to the definition storage part 610 of the data collection device 603, the machine type setting screen being provided for specifying (inputting) the working machine 602. When the machine type is inputted to the machine type setting screen, the extraction part 631 extracts the definition file corresponding to the machine type on the basis of the machine type (a machine type name) inputted to the machine type setting screen.
To be detailed, as shown in
The writing part 632 writes the definition file to the data collection device 603 being to be attached to the working machine 602, the definition file being extracted by the extraction part 631. For example, as described above, after the extraction part 631 extracts the third definition file corresponding to the “M100G”, the writing part 632 sends the third definition file having been extracted to the data collection device 603 connected to the computer 621, and writes the third definition file to the definition storage part 610 of the data collection device 603.
As described above, the writing system 620 according to the fourth embodiment is a system for writing, to the data collection device 603, the setting condition relating to the collection of data, the data collection device 603 being configured to obtain data relating to the working machine, the data being outputted from the working machine 602, and includes the storage part 630 configured to store the plurality of definition files having different setting conditions, the setting conditions being determined for each of data being to be collected. In addition, the writing system 620 includes the extraction part 631 and the writing part 632, the extraction part 631 being configured to extract the definition file corresponding to the working machine 602 from among the plurality of definition files stored in the storage part 630, the writing part 632 being configured to write the definition file to the data collection device 603 being to be attached to the working machine 602, the definition file having been extracted.
Thus, a condition for collection of data corresponding to the working machine 602, that is, the save condition of and the calculation condition of the data can be easily written to the data collection device 603 only by connecting the computer 621 to the data collection device 603 in manufacturing the working machine 602 in a factory or the like, the data collection device 603 being to be mounted on the working machine 602 being to be manufactured.
In particular, the extraction part 631 extracts the definition file corresponding to a machine type of the working machine 602 from among the plurality of definition files. Accordingly, a maker manufacturing the working machine 602, for example, manufactures various types of the working machine 602 such as a tractor, a combine, and a rice transplanter, and the working machines 602 each employ different output intervals of data and different data configurations (a bit number of a signal showing the data); however, the definition files are set for each of machine types of the working machines 602, the definition file corresponding to a machine type is written to the data collection device 603 by using the computer 621, and thereby the data after the collection are shared.
As described above, the data collection device 603 is mounted on the working machine 602, the data collection device 603 having the definition file corresponding to the machine type of the working machine 602, and thereby the data in operation (operation data) of the working machine 602 are easily collected. For example, in a case where the working machine 602 is an agricultural machine such as a tractor, a combine, and the rice transplanter, the operation data generated in an operation of the agricultural machine can be collected.
For example, the operation data such as a revolution speed of a rotary, a load of the rotary, an engine revolution speed, a vehicle speed, a depth of plowing are outputted to the vehicle communication network in a case where a cultivator is coupled as an operation tool to a rear portion of a tractor, and the tractor is operated. The control part 606 is capable of obtaining the operation data such as a revolution speed of a rotary, a load of the rotary, an engine revolution speed, a vehicle speed, a depth of plowing. Meanwhile, the operation data such as a revolution speed of a rotary, a load of the rotary, an engine revolution speed, a vehicle speed, a depth of plowing are detected by an electronic device (an electric component) such as a sensor attached on a tractor and a cultivator.
Or, in a case where the operation tool coupled to the tractor is a fertilizer distributor, an agricultural chemicals distributor, or the seed distributor, the control part 606 is capable of obtaining the operation data such as a vehicle speed, an engine revolution speed, and distribution amounts (a fertilizer distribution amount, the agricultural chemicals distribution amount, and the seed distribution amount). Meanwhile, the distribution amounts (a fertilizer distribution amount, the agricultural chemicals distribution amount, and the seed distribution amount) are also detected by an electronic device (an electric component) attached on a tractor, the fertilizer distributor, the agricultural chemicals distributor, and the seed distributor.
In addition, in a case were the operation tool is a harvest machine, the data such as a vehicle speed, an engine rotation speed, a harvest amount are outputted to the in-vehicle network N1, and the vehicle speed, the engine rotation speed, and the harvest amount can be obtained as the operation data. The harvest amount also can be detected by an electronic device (an electric component) attached on a tractor and a harvest machine.
Meanwhile, it is sometimes required to change: an interval (the save condition in the data collection device 603) of collecting various types of operation data described above (a revolution speed of a rotary, a load of the rotary, an engine revolution speed, a vehicle speed, a depth of plowing, a fertilizer distribution amount, an agricultural chemicals distribution amount, a seed distribution amount, and a harvest amount); and contents (the calculation condition in the data collection device 603) of calculation of the operation data. For example, it is sometimes required to change the save condition of the engine revolution speed from the “every n times of receiving” to the “every t hours”.
Accordingly, as shown in
The setting change part 633 changes the setting condition corresponding to a predetermined data, and stores, to the storage part 630, the definition file having been changed. Concretely, in a case where the setting condition is changed, the setting change part 633 firstly displays a setting screen M1 on the computer 621 as shown in
As shown in
The unchanged display part 635b and the changed display part 635c display the save condition and the calculation condition for each of the data (the identification information), and the changed display part 635c is capable of choosing the save condition and the calculation condition.
To be detailed, the unchanged display part 635b and the changed display part 635c display a check box (a choice part) 638 provided for choosing a condition (an item) for each of the save conditions, and display the check box 638 provided for choosing a condition (an item) for each of the calculation conditions. When the check box 638 is filled in by a check, the save condition and the calculation condition are chosen corresponding to the check box 638.
In a case where a combination of: the data (the identification information) displayed in the unchanged display part 635b; and the setting condition (the save condition or the calculation condition) is different from a combination of: the data (the identification information) displayed in the changed display part 635c; and the setting condition (the save condition or the calculation condition) in the setting screen M1, the setting change part 633 determines that the definition file inputted to the input part 635a is changed, and stores the definition file having a combination of: the data (the identification information) chosen in the changed display part 635c; and the setting condition (the save condition or the calculation condition) to the storage part 630.
For example, as shown in
As described above, when the definition file is changed, the definition file after changed, that is, the setting condition can be written corresponding to the working machine 602. For example, assuming that the a machine type name “M110C” is inputted to a machine type setting screen M2 shown in
As described above, the writing system 620 includes the setting change part 633 configured to change the setting condition relating to a predetermined data and to store the definition file having been changed to the storage part 630, the extraction part 631 extracts the definition file after changed corresponding to the working machine from among the plurality of definition files stored in the storage part 630, the writing part 632 writes the definition file after changed to the data collection device 603 being to be attached to the working machine 602, the definition file being extracted b the extraction part 631, and thereby the setting condition is changed even after the setting condition has been written to the data collection device 603 once.
Meanwhile, in the above described example, in a case where there are a plurality of definition files corresponding to an identical machine type, the extraction part 631 displays the plurality of definition files on the machine type setting screen M2; however, instead of that, the extraction part 631 may extract only the latest definition file from the storage part 630 in a case where there are the plurality of definition files corresponding to the identical machine type.
And, the fourth embodiment described above displays the plurality of definition files on the machine type setting screen M2 in a case where there are the plurality of definition files corresponding to the identical machine type, thereby choosing the definition file being to be written, and further the definition file having been chosen is written or only the latest definition file is written; however, information may be added to the definition file, the information showing whether the definition file is allowed to be written, and the definition file allowed to be written may be written.
As shown in
In a case where there are the plurality of definition files corresponding to the identical machine type, the allowance setting part 636 displays a writing setting screen M3 as shown in
In this manner, in a case where the definition file is related to the information showing allowance of the writing of file and is stored in the storage part 630, the extraction part 631 firstly refers to the definition file corresponding to the working machine from among the plurality of definition file stored in the storage part 630. Then, the extraction part 631 extracts only the definition file allowing the writing from among the definition files having been referred to. The writing part 632 sends the definition file allowing the writing to the data collection device 603 being to be attached to the working machine 602, the definition file having been extracted by the extraction part 631, and writes the definition file.
As described above, even in a case where the allowance setting part 636 is disposed to repeatedly change the definition file, thereby creating the plurality of definition flies corresponding to an identical machine type, only a necessary definition file can be written to the data collection device 603 on the basis of various situations by setting allowance of the writing of the definition file on the basis of specifications of data and of a purpose of collecting the data.
Meanwhile, in the embodiment described above, a method of writing the definition file to the data collection device 603 is explained; however, a computer program (a computer program for changing the setting condition) may be written instead of the definition file. That is, the computer program can be written to the data collection device 603 by reading the computer program as the definition file described above.
That is, the writing system 620 may include the storage part 630 configured to store a plurality of computer programs each having different setting conditions determined for each of data being to be collected. In addition, the writing system 620 may include the extraction part 631 and the writing part 632, the extraction part 631 being configured to extract a program corresponding to the working machine from among a plurality of programs stored in the storage part 630, the writing part 632 being configured to write the program extracted by the extraction part 631 to the data collection device 603 being to be attached to the working machine 602. Moreover, the extraction part 631 may extract the program corresponding to a machine type of the working machine 602 from among the plurality of programs.
Furthermore, the writing system 620 may include the setting change part 633 configured to change the setting condition corresponding to a predetermined data and to store the program having been changed to the storage part 630. The extraction part 631 may extract the program having been changed corresponding to the working machine from among the plurality of programs stored in the storage part 630, and the writing part 632 may write the program after changed to the data collection device 603 being to be attached to the working machine 602, the program being extracted by the extraction part 631. In addition, the writing system 620 may include the allowance setting part 636 configured to set information showing whether the program can be written.
Meanwhile, all the features of the embodiments disclosed in this application should be considered just as examples, and the embodiments do not restrict the present invention accordingly. A scope of the present invention is shown not in the above-described embodiments but in claims, and is intended to include all modifications within and equivalent to a scope of the claims.
In the embodiments described above, the operation data sent from the mobile terminal 3a to the server 2 is accumulated in the collection data accumulation part 21 of the server 2, and the operation data sent from the mobile terminal 3b to the server 2 is also accumulated in the collection data accumulation part 21 of the server 2. Modifying the configuration, the mobile terminal 3a may include the collection data accumulation part 21, and the mobile terminal 3b may include the collection data accumulation part 21; also in this manner, consistency of the operation data accumulated in the collection data accumulation part 21 can be ensured certainly.
Additionally, in the embodiments described above, the working machine includes the hour meter that is a total operation time; however, the present invention can be applied to a working machine including no hour meter. In the embodiments described above, the data collection device 5 collects the operation data after relating the hour meter to the operation data; however, the data collection device 5 may collect the operation data after relating index information (for example, an index number) to the operation data instead of the hour meter, the index information being used for sorting the operation data having been collected. In that case, the data collection processing part 56 stops updating the index information when a checking between the first identification information and the second identification information is unsuccessful.
In the embodiments described above, items showing different modes (methods) of the save conditions are exemplified, for example; in a case where contents shown in the save conditions are slightly different, the save conditions may be considered to be different conditions even when the modes (methods) of the save conditions are identical.
For example, in the save conditions, the “every n times of receiving” and the “at changing” each apparently show different modes (methods) of the save conditions; however, in the “every n times of receiving”, the save condition may be considered to be different conditions when “n” has different numerical values. That is, since the intervals of the saving are different in “every 3 times of receiving” and in “every 10 times of receiving”, the save conditions are considered to be different conditions, and thus the save conditions each having different numerical values “n” may be prepared for each of the machine types. Meanwhile, in the save condition, it is preferred to change, on the setting screen M1, the numerical value of “n” showing the number of receiving; and the numerical value of “t” showing a time.
Similarly, in a case where contents shown in the calculation conditions are slightly different, the calculation conditions may be considered to be different conditions even when the modes (methods) of the calculation conditions are identical. For example, in the calculation conditions, the “accumulation” and the “frequency” each apparently show different modes (methods) of the calculation conditions; however, in the “frequency”, the calculation condition may be considered to be different conditions when the “specified range” has different numerical values. That is, since the ranges are different in the first specified range “600 rpm to 800 rpm” and in the first specified range “580 rpm to 800 rpm”, the calculation conditions are considered to be different conditions, and thus the calculation conditions each having different specified ranges of numerical values may be prepared for each of the machine types. Meanwhile, in the calculation condition, it is preferred to change, on the setting screen M1, the numerical values of the specified ranges shown in the “counting” and the “frequency”; and the specified value shown in the “counting”.
