Although one terminal device 2 is illustrated in
<Work Area>
The lawn area 51 is an area where a lawn is planted. For example, the landscaper performs lawn mowing work using a ride-on lawn mower 61, a walking lawn mower (not illustrated), or the like. Alternatively, the lawn mowing work may be performed by an autonomous robot lawn mower or the like. In the present embodiment, a tree 58 is planted in the lawn area 51, and the landscaper performs the work while avoiding the tree 58 and its surroundings. That is, the tree 58 and its surrounding region are non-entry regions for a working machine.
The grass area 52 is an area where grass is growing. For example, the landscaper performs grass mowing work using a ride-on grass mower 62, a walking grass mower, or the like. Alternatively, the grass mowing work may be performed by an autonomous robot grass mower or the like. In the present embodiment, a pond 55 is arranged in the grass area 52, and the landscaper performs the work while avoiding the pond 55 and its surroundings.
The handheld area 53 is an area where the landscaper performs manual work. In the present embodiment, since the work by the ride-on lawn mower 61, the ride-on grass mower 62, or the like is difficult in a portion adjacent to a building 56 or a passage 57, the landscaper manually performs the work using a handheld working machine 63 such as an edger.
The hedge area 54 is an area where a hedge is planted. For example, the landscaper adjusts an outer shape of the hedge using a trimmer 64.
Note that the method of dividing the work area 5 is expedient according to the work content, and can be appropriately set.
<Data Configuration>
The area information regarding the past work area includes a work division, a size of the work area, and a coefficient. The work division is obtained by dividing regions in the work area according to the work performed by the landscaper. In
The size of the work area is indicated for each work division. For the lawn, the grass, and the handheld, respective areas are indicated. In addition, a surface area of a portion to be a work target is indicated for the hedge. Note that the size of the hedge may be indicated by, for example, an area of a region where the hedge is planted. However, a work amount can be more appropriately grasped by representing the size of the hedge by the surface area.
The coefficient is a value multiplied by the size of the work area. In the present embodiment, each coefficient is set to a value between 1 and 2. The coefficient is used to consider not only the size of the work area but also easiness of work in the work area in identifying a degree of association of the work area to be described later. For example, when there is an inclination in the work area or when it is necessary to perform work while avoiding a waterside of the work area, the work may take more time due to the need to reduce the movement speed of the working machine or the like. Therefore, when an element that causes an increase in work time is present in the work area, a numerical value obtained by multiplying the size of the work area by a predetermined coefficient is used to identify the degree of association of the work area, so that the degree of association of the work area can be identified in consideration of easiness of work in the work area. That is, the value of size×coefficient here can be said to be information used to identify the degree of association of the work area in consideration of the easiness of work in the work area.
In the present embodiment, the area information regarding the past work area includes coefficients regarding an inclination, a waterside, an object, and a plant. That is, in a case where there is an inclination in the work area, in a case where there is a waterside, in a case where there is an object that needs to be avoided, and the like, it is considered that more time is required for work. Therefore, these factors are set as coefficients. In addition, depending on the type of plant to be cut in the work area, it is considered that more time is required for work due to reasons such as hardness and difficulty in cutting. Therefore, the type of plant is also set as a coefficient. Note that a target for which the coefficient is set is not limited to these, and can be set as appropriate.
In the present embodiment, workability information regarding the easiness of work in the work area includes coefficients related to an inclination, a waterside, an object, and a plant, but the workability information may be information other than the coefficients. For example, the workability information may be various types of information regarding workability, such as an average obliquity of the work area, an area of the waterside or the object, and an outer peripheral length of the waterside or the object. Further, for example, the workability information may be information regarding weather such as sunlight, sunlight hours, temperature, humidity, and precipitation in the work area. For example, even in the same plant, since a degree of growth varies depending on the sunlight, the precipitation, and the like, these may affect the work time. Further, for example, when it rains on the day of work or the day before work, the mud in the work area or the like may affect the work time. Therefore, the coefficients described above may be set for these pieces of information.
The time information regarding the past work time includes an actual work time, the number of workers, and the number of working machines. Further, the information regarding the estimation of the work cost includes a fuel consumption amount of the working machine and an actual cost. In the present embodiment, the time information regarding the past work time includes information regarding the work time, information regarding the number of workers, and information regarding the number of working machines for each work division.
In S1, the processing unit 201 executes input reception processing of area information regarding a current work area. The processing unit 201 instructs the input unit 205 to receive the user's input. Here,
Further, in the present embodiment, the input unit 205 can receive input of division information regarding a division of work as the area information. Then, the input unit 205 receives input of the area as the size information and the coefficient as the workability information for each division of each work. The work division may include at least one of lawn work, grass work, manual work, and hedge work. In the present embodiment, the input unit 205 receives a surface area of a work target portion as the size information for the hedge.
Further, in the present embodiment, the input unit 205 receives the number of workers, the number of working machines, and the number of past works to be referred to for each work division as information for displaying associated past work results.
Further, in the present embodiment, the workability information to be input includes information regarding the inclination of the work area, the non-entry region of the working machine in the work area, the object disposed in the work area, and the type of the plant in the work area. Specifically, the input unit 205 is configured to be able to receive coefficients of respective items. Note that the items of the coefficients to be input are not limited, and may include at least one of the exemplified items, or may include items other than the exemplified items.
In S2, the communication unit 203 transmits the area information acquired in S1 to the server device 1 on the basis of a command from the processing unit 201.
In S3, the processing unit 101 of the server device 1 executes reception processing of the area information transmitted from the terminal device 2. The processing unit 101 receives the area information transmitted from the terminal device 2 by the communication unit 103. That is, the processing unit 101 acquires area information regarding the current work area by receiving information from the terminal device 2. Moreover, the processing unit 101 acquires information input by the user to the terminal device 2 as the area information.
In S4, the processing unit 101 identifies a degree of association. The processing unit 101 identifies a degree of association between the area information acquired in S3 and the history information in which the area information regarding the past work area and the time information regarding the work time in the past work area are associated with each other. Details of this step will be described later. In addition, the degree of association here may be an index that can indicate a degree of association between the area information of the current work area and the history information of the past work area. For example, in an example to be described later, a difference between values of size×coefficient between the current work area and the past work area can be used as the degree of association.
In S5, the processing unit 101 identifies output content. Here, the processing unit 101 identifies the output content such that the information included in the history information is output with priority according to the degree of association identified in S4. For example, the processing unit 101 identifies the output content on the basis of the degree of association identified in S4 and the information such as the number of works to be referred to received in S1. For example, in the present embodiment, since the number of works to be referred to received is three, the processing unit 101 identifies three pieces of data as the output content in descending order of the degree of association for each work division. That is, the processing unit 101 may identify information included in the predetermined number of pieces of history information having a high degree of association with the area information of the current work area among the plurality of pieces of history information of the work areas as the output content. In the present embodiment, the information regarding the prescribed number of past work areas is identified as the output content, but the method of identifying the output content is not limited thereto. For example, a threshold value may be set for the degree of association, and all data having the degree of association equal to or more than the threshold value may be included in the output content. For example, as will be described later, in a case where the degree of association is identified by the value of the size of the work area×the coefficient, information regarding the past work area in which a difference in value from the current work area is within a predetermined value or within a predetermined ratio may be included in the output content.
In S6, the communication unit 103 outputs information on the basis of a command from the processing unit 101. That is, the processing unit 101 outputs the content identified in S5 to the terminal device 2 via the communication unit 103. Note that, in the present embodiment, the processing unit 101 outputs the content with priority according to the degree of association for each work division. More specifically, the processing unit 101 outputs a plurality of (three in this example) work results in the past work area having a high degree of association with the current work for each work division (see
In S7, the processing unit 201 of the terminal device 2 executes reception processing of the information transmitted from the server device 1. The processing unit 201 receives the information transmitted from the server device 1 by the communication unit 203.
In S8, the processing unit 201 executes processing of displaying the received information. The processing unit 201 instructs the display unit 204 to display the information received in S7.
Specifically,
In S401, the processing unit 101 selects a prediction target division of the work time. For example, the processing unit 101 selects the lawn as the target division.
In S402, the processing unit 101 identifies a degree of association of past data.
For example, the processing unit 101 identifies a degree of association with the current work area for each piece of data having division IDs of A0001 to A0003. A method of identifying the degree of association can be set as appropriate. For example, the processing unit 101 may identify the degree of association on the basis of the closeness between the past work area size x coefficient value and the current work area size×coefficient value. In addition, the processing unit 101 may determine that the closer these values are, the higher the degree of association with the current work area is. In the present embodiment, the value of the size of the lawn in the current work area×the coefficient is
450(size)×1.3(inclination coefficient)×1.4(object coefficient)=819
(see
Further, for example, the processing unit 101 may identify the degree of association on the basis of the value of the coefficient of the past work area. For example, the processing unit 101 may use, as an index of the degree of association, a sum of absolute values of differences from the respective coefficients of the current work area, a sum of squares of the differences, or the like for the respective pieces of data with the division IDs of A0001 to A0003. Further, the processing unit 101 may determine that the degree of association with the current work area is high in ascending order of these values.
In S403, the processing unit 101 confirms whether or not there is a division for which the degree of association is not identified. When there is a division for which the degree of association is not identified, the processing unit returns to S401, and when there is no division, the processing unit ends the present flowchart.
As described above, according to the present embodiment, since the information included in the history information is output with the priority according to the degree of association with the area information of the current work area, it is possible to present information for the user to predict the work time. Therefore, since the user can predict the work time with reference to the history information in the past work area associated with the current work area, the prediction accuracy of the work time is improved as a result.
The image capturing device 3 is a device for capturing a captured image as information regarding a current work area. The image capturing device 3 may be, for example, a flying body such as a drone, or may be configured to be able to capture an image of the work area from above. Further, for example, the image capturing device 3 may be a moving body capable of traveling on the work area. The moving body may be, for example, a working machine such as an autonomous lawn mower, and a camera for peripheral detection provided in the working machine may function as an image capturing unit 304 described later. Further, for example, the image capturing device 3 may be a monitoring camera or the like. Note that the image capturing device 3 may be possessed by a landscaper, or may be possessed by a manager or the like of the work area. Alternatively, the image capturing device 3 may be a portable terminal such as a digital camera or a smartphone possessed by a general user such as a user in the work area. The image capturing device 3 includes a processing unit 301, a storage unit 302, a communication unit 303, an image capturing unit 304, and a moving unit 305. The processing unit 301, the storage unit 302, the communication unit 303, the image capturing unit 304, and the moving unit 305 are connected by a bus (not illustrated).
The processing unit 301 is a processor represented by a CPU, and executes a program stored in the storage unit 302 to implement various functions related to the image capturing device 3. The storage unit 302 is, for example, a read only memory (ROM), a random access memory (RAM), a hard disk drive (HDD), or a solid state drive (SSD), and stores various types of data in addition to the program executed by the processing unit 301. The communication unit 303 is a communication interface with an external device. The image capturing unit 304 is, for example, a camera, and is configured to be capable of capturing a still image or a moving image. The moving unit 305 moves the image capturing device 3. For example, in a case where the image capturing device 3 is a drone, the moving unit 305 can include a propeller, a motor that drives the propeller, and the like. When the image capturing device 3 is a portable terminal such as a monitoring camera or a digital camera installed in the work area, the moving unit 305 is omitted.
In the present embodiment, the image capturing device 3 can be connected to a terminal device 2 in a wired or wireless manner by the communication unit 303. For example, an image of the work area captured by the image capturing unit 304 is transmitted to the terminal device 2 by the communication unit 303. As a communication method here, known technology can be appropriately adopted, but the terminal device 2 and the image capturing device 3 may be communicable by, for example, wireless fidelity (Wi-Fi), Bluetooth (registered trademark), or the like. Alternatively, the image capturing device 3 may be able to communicate with the server device 1 or the terminal device 2 via a network NW such as the Internet. Note that, although one image capturing device 3 is illustrated in
In S21, the processing unit 301 controls the image capturing unit 304 and the moving unit 305 to capture an image of the work area. Note that the captured image obtained in this step may be a still image or a moving image. For example, in a case where the image capturing device 3 is a drone, an autonomous lawn mower, or the like, the image capturing device 3 starts image capturing of the work area on the basis of reception of an area image capturing instruction or the like from the terminal device 2.
In S22, the communication unit 303 transmits the captured image acquired in S21 to the terminal device 2 on the basis of a command from the processing unit 301.
Note that, although the captured image is transmitted from the image capturing device 3 to the terminal device 2 in the present embodiment, the captured image may be transmitted from the image capturing device 3 to the server device 1. In this case, when the server device 1 receives a transmission request of the captured image from the terminal device 2, the server device 1 may transmit the captured image to the terminal device 2. That is, it is also possible to adopt a configuration in which the captured image of the image capturing device 3 is accumulated in the server device 1, and the terminal device 2 acquires the accumulated captured image from the server device 1 as necessary. Note that the server device 1 may transmit the captured image received from the image capturing device 3 to the terminal device 2 as it is, or may transmit the captured image to the terminal device 2 after the terminal device 2 extracts the captured image required for subsequent processing or performs predetermined image processing.
In S23, the processing unit 201 of the terminal device 2 executes processing of receiving the captured image transmitted from the image capturing device 3. The processing unit 201 receives the captured image transmitted from the image capturing device 3 by the communication unit 203.
In S24, the processing unit 201 executes area determination processing using the received captured image. This processing is processing for dividing the image-captured work area into work divisions. Known image processing technology can be appropriately adopted for the division of the work area.
In S25, the processing unit 201 executes processing for confirming a determination result in S24.
In S26, the processing unit 201 executes area information input reception processing.
Since S2 and subsequent steps are similar to those in
In the present embodiment, the terminal device 2 executes the area determination processing in S24, but the server device 1 may execute the area determination processing. The server device 1 executes the area determination processing, so that it is possible to reduce the processing load on the side of the terminal device 2. In this case, in S22, the captured image of the image capturing device 3 may be transmitted to the server device 1. Then, after executing the area determination processing, the server device 1 may transmit, to the terminal device 2, information necessary for the terminal device 2 to execute the determination result confirmation processing in S25.
In the above embodiment, the server device 1 functions as an information processing device that identifies the degree of association between the current work area and the past work area and outputs information with the priority according to the degree of association. However, the terminal device 2 may function as such an information processing device. In this case, the terminal device 2 may acquire the information regarding the current work area by receiving the user's input by the input unit 205. Alternatively, the terminal device 2 may acquire information regarding the current work area by receiving the captured image from the image capturing device 3 and performing area determination processing or the like on the image. Further, in such a case, for example, a database for storing history information of past works may be constructed in the storage unit 202 of the terminal device 2. Then, the processing unit 201 may identify the degree of association on the basis of the information of the database stored in the storage unit 202. Further, in the server device 1 of the above embodiment, information is transmitted to the terminal device 2 as output of information with the priority according to the degree of association. On the other hand, in the present embodiment, the processing unit 201 of the terminal device 2 may display information on the display unit 204 as output of information with the priority according to the degree of association.
Further, in the above embodiment, information is output for predicting the work time when the landscaper performs work such as lawn mowing or grass mowing in a park, a garden, or the like, but the configuration of the above embodiment can also be applied to other types of works. For example, the configuration of the above embodiment can also be applied to snow removal work by a snow removal machine, cultivation work by an agricultural machine, ground leveling work by a construction machine, and the like.
The above embodiments disclose at least the following work time prediction device, information processing device, terminal device, information processing method, and program.
