[0011] (Embodiment 1) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, work management system 1000 includes work management apparatus 100, work apparatus 200, and terminal 300. Work management apparatus 100 is communicably connected to work apparatus 200 and terminal 300 via network 20, for example, the Internet.

[0012] The work management apparatus 100 stores work performance information related to work that has been previously performed in a field by the work apparatus 200. For example, the work management apparatus 100 acquires operation information on the field from the work apparatus 200, and estimates and stores work performance information, such as the field where the work was performed, the work period, the work type, and the work area, based on the acquired operation information. The work type indicates the type of work performed in the field, such as plowing, leveling, fertilizing, or planting. The work area indicates the area where the work was performed, such as the area within the field where the work was performed, or the entire area of ​​the field where the work was performed.

[0013] Furthermore, when the work device 200 starts work in the field, the work management device 100 transmits work performance information regarding past work performed in the field to the terminal 300. The terminal 300 notifies the user of the received work performance information. For example, as shown in FIG. 2, the terminal 300 displays work performance information regarding work performed in the field 10 in the past. In the example shown in FIG. 2, the terminal 300 displays the work date on which the work was performed in the field 10, the work type, and the amount of pesticide sprayed at each position in the field 10 during the work. For example, the terminal 300 indicates that the amount of pesticide sprayed in the first performance area 11 of the field 10 is less than the amount of pesticide sprayed in the second performance area 12. The terminal 300 also indicates that the amount of pesticide sprayed in the second performance area 12 is less than the amount of pesticide sprayed in the third performance area 13.

[0014] The user can check the work history information displayed on the terminal 300 to confirm work that has been previously performed in the field 10. When the work history information includes work that the work device 200 is to start in the field 10, the user can know that work is already being performed in the field 10. Therefore, the work management system 1000 can reduce the number of times the same work is performed twice. The work management system 1000 is particularly effective in reducing the number of times work is performed repeatedly, such as fertilizing or spraying pesticides, which is difficult to determine from the appearance of the field 10. Furthermore, when multiple workers are working together, the work management system 1000 can prevent other workers from mistakenly repeating the same work in the field 10 after the work has been completed.

[0015] The operation information acquired from the work implement 200 includes information that indicates the state of the work implement 200 when work is being performed in the field 10, such as the speed, steering angle, engine RPM, ON / OFF status of various clutches, position information of the work implement 200 at each time, and work period. When the work implement 200 is a vehicle that tows a work machine, such as a tractor, the operation information may also include information such as the PTO (power take-off) RPM when transmitting power to the work machine, and the hitch height and lift arm angle that indicate the attitude of the work machine.

[0016] (Work management system configuration) The configuration of the task device 200 shown in FIG. 1 will be described. The task device 200 moves within a field to perform various tasks, and includes, for example, a tractor, a rice transplanter, a fertilizer applicator, and a drone. In particular, the task device 200 includes equipment for fertilizing and spraying pesticides. The task device 200 is equipped with a task control device 205. The task control device 205 controls the operation of the task device 200, such as the speed, steering angle, and amount of pesticide sprayed by the task device 200. The task control device 205 also transmits operation information indicating the status of the task device 200 to the task management device 100. As shown in FIG. 3, the task control device 205 includes an input / output device 210, a calculation device 220, a communication device 230, a storage device 240, and a positioning device 245.

[0017] Information for the arithmetic unit 220 to execute processing is input to the input / output device 210. The input / output device 210 also outputs the results of processing executed by the arithmetic unit 220. The input / output device 210 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel.

[0018] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 230 transfers signals acquired from the work management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the work management device 100. The communication device 230 includes various interfaces, such as a wireless LAN (Local Area Network) transceiver, a NIC (Network Interface Card), and a USB (Universal Serial Bus).

[0019] The positioning device 245 measures the position of the task device 200 at each time, for example, the latitude and longitude. Position information indicating the measured position is transmitted to the calculation device 220. The positioning device 245 measures the position of the task device 200 at each time by incorporating the work control device 205 into the task device 200. The positioning device 245 is, for example, a GNSS (Global Navigation Satellite System) receiver.

[0020] The storage device 240 stores various data for controlling the work device 200, such as the work control program 400. The storage device 240 is used as a non-transitory tangible storage medium for storing the work control program 400. The work control program 400 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 downloadable from a server.

[0021] The arithmetic device 220 reads and executes the work control program 400 to implement the work control unit 250 as shown in Figure 4. The work control unit 250 controls the operation of the work device 200. The work control unit 250 also transmits position information of the work device 200 to the work management device 100.

[0022] Next, the configuration of the work management device 100 will be described. As shown in FIG. 5, the work management device 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. Information used by the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 also outputs the results of processing executed by the calculation device 120. The input / output device 110 includes various input and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. The input / output device 110 may be omitted.

[0023] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 130 transfers operation information acquired from the maintenance device 200 to the calculation device 120. The communication device 130 also transfers signals generated by the calculation device 120 to the terminal 300. The communication device 130 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0024] The storage device 140 stores various data for managing work performed in the field 10, such as performance data 410, plan data 420, and a work management program 430. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 430. The work management program 430 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 downloadable from a server. The work management program 430 may also be provided by being recorded on the storage medium 1 shown in FIG. 3.

[0025] The performance data 410 shown in FIG. 5 includes data on work previously performed in the field 10, such as data calculated from operation information from the work device 200. For example, the performance data 410 includes information that associates a work period, a work area, and a work type. The work period indicates the time when work in the field 10 started and ended. The work area indicates the area in the field 10 where work was performed, such as the first performance area 11 shown in FIG. 2. The work type indicates the type of work performed in the field 10, such as plowing, leveling, fertilizing, or planting. The performance data 410 also includes information that indicates the amount of materials used at each position in the field 10, such as the amount of pesticide or fertilizer applied.

[0026] The plan data 420 includes data for controlling the implement 200 to perform work in the field 10. For example, as shown in FIG. 6 , the plan data 420 includes information representing the field 10 where work will be performed, the area of ​​the field 10, the type of work, and the planned path 18 of the implement 200 when performing the work. The plan data 420 also includes information representing the amount of materials to be used at each position in the field 10. For example, the plan data 420 includes information representing the amount of pesticide to be sprayed by the implement 200 in each of the first plan area 15, the second plan area 16, and the third plan area 17 of the field 10. The plan data 420 may also include a work ID representing the identifier of the recorded work plan.

[0027] 5 reads performance data 410 and performs various data processing to output performance information related to work that has been previously performed in the field 10. The calculation device 120 also reads plan data 420 and transmits work plan information represented in the plan data 420 to the work control device 205 so that the work control device 205 controls the work device 200. For example, the calculation device 120 includes a central processing unit (CPU) and the like.

[0028] By reading and executing the work management program 430, the arithmetic device 120 realizes a data storage unit 150, a start determination unit 160, and an output unit 170, as shown in FIG. 4. The data storage unit 150 stores performance data 410 and plan data 420. The start determination unit 160 determines whether or not the work device 200 will start work in the field 10. When the work device 200 starts work in the field 10, the output unit 170 outputs work performance information related to work that has been previously performed in the field 10.

[0029] Next, the configuration of the terminal 300 will be described. As shown in Fig. 7, the terminal 300 includes an input / output device 310, an arithmetic device 320, a communication device 330, and a storage device 340. The terminal 300 includes, for example, a computer, a tablet, a mobile phone, etc. Information used by the arithmetic device 320 to execute processing is input to the input / output device 310. The input / output device 310 also outputs the results of processing executed by the arithmetic device 320. The input / output device 310 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel.

[0030] The communication device 330 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 330 transfers work performance information acquired from the work management device 100 to the calculation device 320. The communication device 330 also transfers signals generated by the calculation device 320 to the work management device 100. The communication device 330 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0031] The storage device 340 stores various data for notifying the user of work performance information, for example, a notification program 440. The storage device 340 is used as a non-transitory tangible storage medium for storing the notification program 440. The notification program 440 may be provided as a computer program product recorded on a computer-readable storage medium 3, or may be provided as a computer program product downloadable from a server. The notification program 440 may be provided by being recorded on the storage medium 1 shown in FIG. 3.

[0032] By reading and executing the notification program 440, the arithmetic device 320 realizes a notification unit 350 that cooperates with the input / output device 310 to notify the user of the work performance information obtained from the work management device 100, as shown in FIG. 4.

[0033] (Work management system operation) When the work device 200 is started, for example when the engine is started, the arithmetic device 220 of the work control device 205 shown in Figure 3 reads and executes the work control program 400. By reading and executing the work control program 400, the arithmetic device 220 executes part of the processing shown in Figure 8, which is a work management method.

[0034] In step S110, the work control unit 250 implemented by the calculation device 220 acquires position information indicating the position of the work device 200 from the positioning device 245. The work control unit 250 transmits the acquired position information of the work device 200 to the calculation device 120 of the work management apparatus 100. For example, when the work device 200 is a vehicle, the work device 200 moves from a storage location to the field 10. When the work device 200 moves from the storage location to the field 10, the work control unit 250 transmits position information indicating the position of the work device 200 to the calculation device 120 of the work management apparatus 100.

[0035] In step S120, upon receiving position information from the work control unit 250 of the work control device 205, the calculation device 120 of the work management device 100 reads and executes the work management program 430. The start determination unit 160 implemented in the calculation device 120 determines whether or not the work device 200 will start work, based on the position of the work device 200. If it is determined that the work device 200 will not start work, the process returns to step S110 and is repeated. If it is determined that the work device 200 will start work, the process proceeds to step S130.

[0036] For example, when the distance from the work device 200 to the field 10 is smaller than a threshold value, the start determination unit 160 determines that the work device 200 will start work. Specifically, the start determination unit 160 extracts area information representing the area of ​​the field 10 from the plan data 420, and calculates the distance from the position of the work device 200 represented in the position information to the area of ​​the field 10 represented in the area information. The distance from the position of the work device 200 to the area of ​​the field 10 represents the distance from the position of the work device 200 to the point in the area of ​​the field 10 that is closest to the position of the work device 200. When the calculated distance is smaller than the threshold value, the start determination unit 160 determines that the work device 200 will start work.

[0037] In step S130, the output unit 170 outputs notification information representing at least a portion of the work performance information of work previously performed in the field 10 to the arithmetic device 320 of the terminal 300. For example, the output unit 170 extracts work performance information representing work previously performed in the field 10 from the performance data 410. The output unit 170 may also extract work performance information representing one or more works most recently performed in the field 10 from the works stored in the performance data 410. For example, the output unit 170 extracts work performance information representing one work most recently performed in the field 10 from the performance data 410. The output unit 170 may also extract work performance information representing work performed by a work device 200 that has started work in the field 10 from the works recorded in the performance data 410. The extracted work performance information is transmitted to the arithmetic device 320 of the terminal 300 as notification information. For example, the output unit 170 generates a notification signal representing the extracted work performance information, and transmits the generated notification signal to the arithmetic device 320 of the terminal 300.

[0038] In step S140, upon receiving the notification information, the arithmetic device 320 of the terminal 300 reads and executes the notification program 440. The notification unit 350 implemented by the arithmetic device 320 outputs the notification information to the input / output device 310. For example, the notification information indicates the amount of materials used in at least a portion of the field 10, for example, the first performance area 11, as shown in FIG.

[0039] In step S150, the work control unit 250 determines whether the user has input a command to start work. For example, in step S140, the user checks the notification information output to the input / output device 310 to confirm whether the work to be started by the work device 200 is already being performed in the field 10. When the work to be started by the work device 200 is already being performed, the user ends the work without inputting an operation to start the work by the work device 200 to the input / output device 210 of the work control device 205. This ends the processing of the work management method shown in FIG. 7.

[0040] On the other hand, when no work is being started by the work apparatus 200, the user inputs an operation to start work by the work apparatus 200 to the input / output device 210 of the work control device 205. When an operation to start work by the work apparatus 200 is input, the work control unit 250 executes the processing of step S160.

[0041] In step S160, the work control unit 250 controls the work device 200 to start work in the field 10. The work control unit 250 acquires work plan information for starting work in the field 10, as shown in FIG. 6, from the data stored in the plan data 420. Based on the acquired work plan information, the work control unit 250 controls the work device 200 to perform work in the field 10. When the work device 200 finishes work in the field 10, the work management method shown in FIG. 8 ends.

[0042] In this way, before the work device 200 starts work in the field 10, the work management system 1000 notifies the user of notification information indicating work that has been previously performed in the field 10. The user can check based on the notification information whether the work to be started has already been performed, thereby reducing the chance of accidentally repeating the same work.

[0043] (Variation) The configuration described in the embodiment is an example, and the configuration can be changed as long as it does not impair functionality. The start determination unit 160 may determine in step S120 that the task device 200 is about to start work in the field 10, and may use any method to determine that work will start. For example, when the work control unit 250 of the work control device 205 controls the task device 200 to start work in the field 10, the work control unit 250 may generate a work start signal indicating that work in the field 10 will start, and transmit the signal to the start determination unit 160 of the work management device 100. Upon receiving the work start signal from the work control unit 250, the start determination unit 160 determines that the task device 200 will start work in the field 10. In this case, the process of step S110, in which the start determination unit 160 acquires position information from the work control unit 250, may be omitted.

[0044] In step S150, the work control unit 250 may output, from the plan data 420, a plurality of pieces of work plan information representing work in the field 10 at which the work device 200 is to start work, to the input / output device 210. The user inputs the start of work by selecting the work that the work device 200 is to start from the plurality of pieces of output work plan information.

[0045] Furthermore, when outputting multiple pieces of work plan information to the input / output device 210, the work control unit 250 may send to the work management apparatus 100 a work start signal indicating that work is about to start in the field 10. When the calculation device 120 of the work management apparatus 100 receives the work start signal, it determines that the work device 200 will start work in the field 10, and performs the processes from step S130 onwards shown in Figure 8.

[0046] In step S130, the output unit 170 may transmit notification information indicating an identifier corresponding to the work stored in the performance data 410 to the work control unit 250 of the work control device 205. In this case, the work control unit 250 extracts the work identifier from the notification information, and obtains work plan information indicating the work corresponding to the extracted identifier from the plan data 420. The work control unit 250 displays the obtained work plan information on the input / output device 210, and notifies the user of the notification information.

[0047] Furthermore, when the user selects a task to be started in the field 10 from multiple pieces of work plan information stored in the plan data 420, the work control unit 250 may extract a task identifier from the notification information and output multiple pieces of work plan information excluding the task corresponding to the extracted identifier. In this case, work plan information for tasks that have already been performed is not displayed on the input / output device 210 and therefore cannot be selected by the user. This reduces the chance of accidentally repeating the same task.

[0048] Furthermore, the work control unit 250 may output multiple pieces of work plan information so that work plan information corresponding to the work identifier extracted from the notification information can be distinguished from other work plan information. For example, the work control unit 250 displays work plan information corresponding to the extracted work identifier in a color different from that of other work plan information. This reduces the chance of the user selecting work plan information corresponding to work that has already been performed when selecting work plan information corresponding to work to be started in the field 10.

[0049] The work control device 205 shown in FIG. 1 may acquire the plan data 420 from the work management device 100 using any method. For example, the work control device 205 may acquire the plan data 420 from the work management device 100 via the terminal 300. Specifically, the terminal 300 acquires the plan data 420 from the work management device 100 via the network 20 and stores the acquired plan data 420 on a storage medium, such as a USB memory stick. The storage medium on which the plan data 420 is stored is connected to the work control device 205, and transfers the plan data 420 to the work control device 205. The work control unit 250 of the work control device 205 may also acquire the plan data 420 from the work management device 100 in step S160 shown in FIG. 8.

[0050] The above-described embodiments and modifications are merely examples. The configurations described in each embodiment and modification may be modified and / or combined as desired without impairing functionality. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the necessary functionality is achieved. For example, the notification unit 350 may be implemented by the work control device 205. Furthermore, all or part of the data storage unit 150, start determination unit 160, and output unit 170 may be implemented by the work control device 205 or the terminal 300. In this case, the work management program 430 may include all or part of the notification program 440 and the work control program 400, and the work management program 430 may be stored in the work control device 205 or the terminal 300.
