A work management system 1000 according to an embodiment of the present disclosure will be described with reference to the drawings. In this embodiment, as illustrated in
The work vehicle 30 moves in a field 500 and thus performs agricultural work. The work device 30 includes, for example, a harvester, such as a tractor, a combine, or the like, to which various work machines are attached, a spraying machine, such as a drone or the like, that sprays an agricultural chemical, or the like.
The work device 30 outputs operation information at each time to the work management device 100. For example, the operation information includes position information representing a position of the first work device 30 at each time. The work device 30 includes a positioning device, such as, for example, a receiver of a global navigation satellite system (GNSS), a quantum compass, or the like, that measures the position at each time. For example, the work device 30 measures the position of the work device 30 itself at predetermined intervals, that is, for example, at intervals of 10 seconds, and acquires position information representing a time of the measurement and the position of the work device 30 itself in association with each other.
The operation information also includes state information representing a state of the first work device 30, such as, for example, a speed, a steering angle, an engine speed, an ON/OFF status of each of various clutches, or the like of the first work device 30 at each time while the work device 30 is performing work in the field 500. When the work device 30 is a vehicle, that is, for example, a tractor, that tows a work machine, the operation information may include information, such as a power take-off (PTO) rotation speed at a time of transmitting power to the work machine, a hitch height and a lift arm angle indicating a posture of the work machine, or the like. For example, the work device 30 measures a state of the work device 30 itself at predetermined intervals, that is, for example, at intervals of 10 seconds, and acquires state information representing a time of the measurement and the state of the work device 30 itself in association with each other.
The work management device 100 determines an operation status of the work device 30 at each time, that is, for example, working, moving, stopped, not operating, or the like, based on the operation information of the work device 30. The work management device 100 also determines a ridge on which the work device 30 is performing work at each time, based on the position information of the work device 30. Note that the operation status represents an overview of a status in which the work device 30 is operating, and represents, for example, a classification in accordance with whether the work device 30 is operating and the speed of the work device 30. For example, “working” represents that the work device 30 was performing agricultural work, and “moving” represents that the work device 30 was moving without performing agricultural work. “Stopped” represents that the work device 30 was stopped with a drive device, such as, for example, an engine, of the work device 30 running, and “not operating” represents that the drive device of the work device 30 was stopped.
The terminal 200 displays the operation status of the work device 30 in association with the ridge on which the work device 30 is performing work at each time. For example, as illustrated in
A configuration of the work management device 100 included in the work management system 1000 will be described. As illustrated in
The storage device 140 stores various data, that is, for example, field data 310 and a work management program 320, used for determining the operation status of the work device 30 and the ridge 510 on which work was performed at each time. The storage device 140 is used as a non-transitory tangible storage medium that stores the work management program 320. The work management program 320 may be provided as a computer program product recorded on a computer-readable storage medium 1 or may be provided as a computer program product that can be downloaded from a server.
The field data 310 stores ridge information related to the ridge 510 provided in the field 500. For example, the ridge information represents a position of the ridge 510. For example, the ridge information may represent a line connecting both ends of the ridge 510, may represent, for example, a straight line segment, or may represent an area of the ridge 510.
The arithmetic operation device 120 reads and executes the work management program 320 from the storage device 140 to perform various kinds of data processing to determine the operation status of the work device 30 and the ridge 510 on which work was performed. Examples of the arithmetic operation device 120 include, for example, a central processing unit (CPU) or the like.
By reading and executing the work management program 320, as illustrated in
Next, a configuration of the terminal 200 will be described. As illustrated in
The communication device 230 is electrically coupled to the network 20 and performs communication with each of the devices via the network 20. The communication device 230 transfers information acquired from the work management device 100 to the arithmetic operation device 220. The communication device 230 transfers a signal generated by the arithmetic operation device 220 to the work management device 100. The communication device 230 includes, for example, various interfaces, such as a network interface card (NIC), a universal serial bus (USB), or the like.
The storage device 240 stores various data, that is, for example, a display program 330, used for displaying the work information representing the operation status of the work device 30 and the ridge 510 on which work was performed in association with each other on the input/output device 210 of the terminal 200. The storage device 240 is used as a non-transitory tangible storage medium that stores the display program 330. The display program 330 may be provided as a computer program product recorded on a computer-readable storage medium 2, or may be provided as a computer program product that can be downloaded from a server.
The arithmetic operation device 220 reads and executes the display program 330, and thus, performs various kinds of data processing to display the work information that is acquired from the work management device 100. Examples of the arithmetic operation device 220 include, for example, a central processing unit (CPU) or the like.
When the arithmetic operation device 220 reads and executes the display program 330, the arithmetic operation device 220 realizes a display section 250 in cooperation with the input/output device 210, as illustrated in
A method by which the work management system 1000 determines work information will be described. As illustrated in
When the arithmetic operation device 120 of the work management device 100 receives the operation information from the work device 30, the arithmetic operation device 120 reads and executes the work management program 320 to start processing illustrated in
For example, the operation status determination section 150 determines the operation status of the work device 30 at each time, based on a speed of the work device 30 represented in the operation information. For example, the operation status determination section 150 determines, when the speed of the work device 30 is higher than a first threshold, that the work device 30 was moving (moving) at a time represented in the operation information, that is, for example, at a time when the speed of the work device 30 was measured. Moreover, the operation status determination section 150 determines, when the speed of the work device 30 is equal to or lower than the first threshold and is higher than a second threshold, that the work device 30 was working (working) at a time represented in the operation information. The operation status determination section 150 determines, when the speed of the work device 30 is equal to or lower than the second threshold, that the work device 30 was stopped (stopped) at a time represented in the operation information. The operation status determination section 150 determines, at a time when the operation information is not acquired by the work device 30, that the work device 30 was not operating (not operating). The speed of the work device 30 may be included in the state information of the work device 30, and may be determined from the position information of the work device 30. For example, the speed of the work device 30 may be determined based on a distance between two measured positions and an interval between measurement times in two pieces of position information whose measurement times are adjacent to each other.
In Step S120, the ridge determination section 160 determines the ridge 510 on which work is being performed at each time, based on the position information included in the operation information of the work device 30. For example, the ridge determination section 160 acquires ridge information representing a position of the ridge 510 in the field 500 from the field data 310.
The ridge determination section 160 determines that work is being performed on the ridge 510 that is located at a predetermined distance, that is, for example, 20 cm, or less from the position of the work device 30 at each time. Moreover, the ridge determination section 160 may be configured to determine the ridge 510 located at the predetermined distance or less from the position of the work device 30 continuously for a predetermined time, that is, for example, one minute or more, as the ridge 510 on which the work device 30 is performing work. The ridge determination section 160 may be configured to, when the ridge information represents an area of the ride 510, determine the ridge 510 including the position of the work device 30 as the ridge 510 on which work is being performed at each time. Furthermore, the ridge determination section 160 may be configured to determine the ridge 510 including the position of the work device 30 continuously for the predetermined time or more as the ridge 510 on which work is being performed at each time.
In Step S130, the output section 170 outputs the work information representing the operation status of the work device 30 and the ridge 510 on which work is being performed to the terminal 200 at each time. For example, as illustrated in
In the work information display area 410, information including the operation status of the work device 30 and the ridge 510 on which work is being performed in association with each other is represented at each time. For example, in the work information display area 410, each time is represented in a strip shape, the operation status of the work device 30 at each time and the ridge 510 on which work is being performed are represented in a position corresponding to a position in which the corresponding each time is represented. The work information display area 410 includes, for example, a time display area 420 representing each time, an operation status display area 430 representing the operation status of the work device 30, and a work ridge display area 440 representing the ridge 510 on which the work device is working.
In an example illustrated in
In accordance with a position in which a time is represented in the time display area 420, the ridge 510 on which work was performed at the time is represented in the work ridge display area 440. In the work ridge display area 440, for example, work time information 441 representing a period in which work was performed on the ridge 510, ridge identification information 442 representing the ridge 510 on which the work is performed, and, for example, an identifier representing the ridge 510 are represented. For example, the work time information 441 is represented as an area in a display format in which the ridge 510 is represented below the position in which the time at which work on the ridge 510 was performed is represented in the time display area 420. For example, when work was performed in a period from 7:10 to 8:15 on a first ridge 510-1, an area in which the first ridge 510-1 is represented is represented as the work time information 441 below a position in which a period from 7:10 to 8:15 is represented in the time display area 420. Furthermore, the ridge identification information 442 representing the ridge 510 on which the work was performed, that is, for example, a number representing the ridge 510, is represented in a position corresponding to the work time information 441. For example, the ridge identification information 442 is represented so as to be adjacent to a position in which the work time information 441 is represented. For example, the ridge identification information 442 is represented below the position in which the work time information 441 is represented.
In the ridge information display area 480, the work time information 441 and the position of the ridge 510 represented by the ridge identification information 442 are represented in the field 500. For example, in the ridge information display area 480, the field 500, the position of the ridge 510 in the field 500, and the ridge identifier 520 of the ridge 510 are displayed on a map. For example, the ridge 510 is represented in a display format, that is, for example, a color, a pattern, a line type, or the like, different from that of the other ridges 510. For example, the ridge 510 represented in the ridge information display area 480 is represented in a same display format as that of the work time information 441 in the work ridge display area 440. Moreover, the ridge identifier 520 represented in the ridge information display area 480 is represented in a same notation, that is, for example, a same character, as that of the ridge identification information 442 in the work ridge display area 440.
Therefore, the display image 400 illustrated in
As described above, the work information that is output from the output section 170 to the terminal 200 may represent the display image 400 representing the operation status of the work device 30 and the ridge 510 on which work is being performed in association with each other at each time.
In Step S140 illustrated in
The user can easily confirm the ridge 510 on which the work device 30 performed work and the operation status of the work device 30 then at each time by browsing the work information, that is, for example, the display image 400, displayed on the input/output device 210.
As illustrated in
As illustrated in
Herein, the following device 40 includes a positioning device, such as, for example, a receiver of a global navigation satellite system (GNSS), a quantum compass, or the like, that measures a position at each time. Position information representing the measured position of the following device 40 is output from the following device 40 to the work management device 100.
A configuration of the work management system 1000 is similar to that in the first embodiment, except that the work management device 100 executes the work management program 320 to realize a following device determination portion 180, as illustrated in
A method by which the work management system 1000 determines work information will be described. Similar to the first embodiment, the work device 30 outputs the operation information to the work management device 100. The following device 40 also outputs the position information to the work management device 100. For example, when the following device 40 is operating, the following device 40 successively outputs the position information to the work management device 100. The following device 40 may be configured to, when the drive device, that is, for example, an engine, a motor, or the like, is stopped, output the position information from a time when the drive device is started to a time when the drive device is stopped to the work management device 100.
When the arithmetic operation device 120 of the work management device 100 receives the operation information from the work device 30 and also receives the position information from the following device 40, the arithmetic operation device 120 reads and executes the work management program 320 to start processing illustrated in
In Step S125, the following device determination section 180 determines the following device 40 that follows the work device 30, based on the position information of the work device 30 and the position information of the following device 40, at each time. For example, the following device determination section 180 determines the following device 40 that is located at a predetermined distance, that is, for example, 3 m, or less from the position of the work device 30 as the following device 40 that follows the work device 30 at each time. In addition, the following device determination section 180 may be configured to determine the following device 40 that is located at the predetermined distance or less from the position of the work device 30 continuously for a predetermined time, that is, for example, one minute or more, as the following device 40 that follows the work device 30.
In Step S130B, the output section 170 outputs the work information representing the operation status of the work device 30, the ridge 510 on which work is being performed, and the following device 40 that follows the work device 30 to the terminal 200 at each time. For example, as illustrated in
In the work information display area 410B, information including the operation status of the work device 30, the ridge 510 on which work is being performed, and the following device 40 that follows the work device 30 in association with each other is represented at each time. For example, in the work information display area 410B, each time is represented in a strip shape, the operation status of the work device 30 at each time, the ridge 510 on which work is being performed, and the following device 40 that follows the work device 30 are identifiably represented in a position where a corresponding time is represented. The work information display area 410B includes, for example, a time display area 420, an operation status display area 430, a work ridge display area 440, and a following device display area 450. Since the time display area 420 and the operation status display area 430 are similar to those in the first embodiment, description thereon will be omitted.
In the following device display area 450, the following device 40 that follows the work device 30 is represented at each time. In an example illustrated in
When a plurality of following devices 40 follow the work device 30, the following devices 40 that follow the work device 30 are identifiably represented in the following device display area 450. For example, in an up and down direction, respective periods in which the following devices 40 follow the work device 30 are represented in different positions from each other. For example, below a position where a period in which a first following device 40, that is, for example, the first vehicle, follows the work device 30 is represented, represented is a period in which a second following device 40, that is, for example, a second vehicle, follows the work device 30.
As described above, the work information that is output from the output section 170 to the terminal 200 may represent the display image 400B representing the operation status of the work device 30, the ridge 510 on which work is being performed, and the following device 40 that follows the work device 30 in association with each other at each time. In Step S140 illustrated in
The user can easily confirm the ridge 510 on which the work device 30 performed work at each time and the following device 40 that followed the work device 30 then by browsing the work information, that is, for example, the display image 400B, displayed on the input/output device 210.
