MODE FOR CARRYING OUT THE INVENTION

[0012] (Embodiment 1) The agricultural information management system 1000 according to the present embodiment of the present invention will be described with reference to the drawings. In the present embodiment, as shown in FIG. 1, the agricultural information management system 1000 includes an agricultural information management device 100 and a terminal 200. The agricultural information management device 100 is communicably connected to the terminal 200 and at least one or more agricultural working machines 30 via a network 20, for example, the Internet.

[0013] The agricultural work machine 30 performs agricultural work by moving within the field. The agricultural information management device 100 acquires operation information in the field from the agricultural work machine 30 and stores agricultural data 300 representing a work area, a planting amount, an amount of pesticide sprayed, a harvest amount, etc. based on the acquired operation information. The agricultural work machine 30 includes, for example, a tractor, a rice transplanter, a harvester such as a combine, a spraying machine for spraying pesticides such as a drone, etc. Further, the agricultural work machine 30 may include a transport vehicle for transporting harvested products, materials, etc.

[0014] The operation information includes information representing the state of the agricultural work machine 30 when working in the field, and includes, for example, information representing the speed, steering angle, engine speed, ON / OFF status of various clutches, position information of the agricultural work machine 30 at each time, etc. When the agricultural work machine 30 is a vehicle that pulls a working device, for example, a tractor, the operation information may include information such as the PTO (power take-off) rotation speed when transmitting power to the working device, the hitch height and lift arm angle indicating the attitude of the working device.

[0015] The agricultural information management device 100 outputs information regarding the stored agricultural data 300 in response to a request from the terminal 200. The terminal 200 displays the output information. For example, as shown in FIG. 2, the terminal 200 displays a list image 500 representing the amount of work, for example, the harvest amount, the work area, the amount of seedling planting, the amount of fertilizer spraying, etc. for each agricultural work machine 30.

[0016] In this way, the agricultural information management system 1000 can provide the user with the amount of work for each agricultural work machine 30. Thereby, the user can grasp the working status of each agricultural work machine 30 more accurately.

[0017] (Configuration of Agricultural Information Management System) The configuration of the agricultural information management device 100 included in the agricultural information management system 1000 will be described. As shown in FIG. 1, the agricultural information management device 100 includes an input / output device 110, an arithmetic device 120, a communication device 130, and a storage device 140. The agricultural information management device 100 is, for example, a computer. Information for the arithmetic device 120 to execute processing is input to the input / output device 110. Also, the input / output device 110 outputs the result of the processing executed by the arithmetic device 120. The input / output device 110 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like. The input / output device 110 may be omitted.

[0018] 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 the operation information acquired from the agricultural work machine 30 to the arithmetic device 120. Also, the communication device 130 transfers the signal generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces such as, for example, a NIC (Network Interface Card), a USB (Universal Serial Bus), and the like.

[0019] The storage device 140 stores various data for calculating information representing the work amount for each agricultural work machine 30, for example, agricultural data 300, and an agricultural information management program 320. The storage device 140 is used as a non-transitory tangible storage medium for storing the agricultural information management program 320. The agricultural information 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 downloadable from a server.

[0020] As shown in Fig. 3, the agricultural data 300 includes evaluation indicators 301 associated with each agricultural working machine 30. The evaluation indicators 301 include operation information 302, trajectory information 303, operation time information 304, environmental information 305, and work volume information 306. The operation information 302 represents each piece of information obtained from the agricultural working machine 30. For example, the operation information 302 includes the speed, steering angle, engine load rate, etc. of the agricultural working machine 30.

[0021] The trajectory information 303 represents the trajectory along which the agricultural working machine 30 has moved, calculated based on the operation information 302. The agricultural working machine 30 is equipped with a positioning device, such as a receiver of GNSS (Global Navigation Satellite System), and acquires position information representing the position at each moment of movement. The trajectory information 303 is calculated based on the position information.

[0022] The operation time information 304 represents the time during which the agricultural working machine 30 has been operating, for example, the time from when the engine is started until it stops. Also, the operation time information 304 represents the time of a plurality of working states in which the state of the agricultural working machine 30 at each moment is classified based on the operation information 302, such as during work, stopped, moving, non-operating, etc. For example, the operation time information 304 represents the working state of the agricultural working machine 30 at each moment.

[0023] The environmental information 305 represents the state of the field where the agricultural working machine 30 has performed work. For example, the environmental information 305 represents the size of the field where the agricultural working machine 30 has performed work, the hardness of the soil, and the soil properties such as sandy or clayey represented by the particle size composition of the soil. Also, the environmental information 305 may represent the precipitation in the field, the lodging state of the crops, etc.

[0024] The work amount information 306 represents the work amount performed by the agricultural machine 30. For example, the work amount information 306 includes area information 307 regarding the area where the work was performed and material information 308 representing the amount of materials used in the work and the harvest amount. The area information 307 includes, for example, the working area of the area where the work was performed, the working area where the work was performed per unit time, the traveling distance that the transport vehicle transported materials, etc. The material information 308 includes the harvest amount of the harvested crops, the amount of fertilizers and pesticides sprayed, the amount of planted crops, the seeding amount, etc. Further, the material information 308 may include the amount of fuel consumed in the work. The material information 308 may include the material usage amount per unit area, the harvest amount per unit area, and the working area per fuel consumption amount.

[0025] The field data 310 shown in FIG. 1 represents information regarding the field where the agricultural machine 30 performs work. For example, the field data 310 includes the size of the field, the field area, the hardness of the soil in the field, the soil properties in the field, the lodging state of the crops in the field, the precipitation amount in the field, etc. Further, the field data 310 may represent the degree of drainage, for example, whether it is a paddy field or a dry field.

[0026] The arithmetic unit 120 reads and executes the agricultural information management program 320 from the storage device 140 and performs various data processes for calculating information representing the work amount for each agricultural machine 30. For example, the arithmetic unit 120 includes a central processing unit (CPU; Central Processing Unit), etc.

[0027] By reading and executing the agricultural information management program 320, the arithmetic unit 120 realizes, as shown in FIG. 4, a data storage unit 150, an evaluation index calculation unit 160, and an output unit 170. The data storage unit 150 stores the agricultural data 300. The evaluation index calculation unit 160 calculates various information included in the evaluation index 301 based on the agricultural data 300. The output unit 170 outputs display information representing the calculated evaluation index 301.

[0028] Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, the terminal 200 includes an input / output device 210, an arithmetic device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, etc. Information for the arithmetic device 220 to execute processing is input to the input / output device 210. Further, the input / output device 210 outputs the result of the processing executed by the arithmetic device 220. The input / output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, etc.

[0029] 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 the information acquired from the agricultural information management device 100 to the arithmetic device 220. Further, it transfers the signal generated by the arithmetic device 220 to the agricultural information management device 100. The communication device 230 includes various interfaces such as, for example, a NIC (Network Interface Card), a USB (Universal Serial Bus).

[0030] The storage device 240 stores various data for displaying the evaluation index 301 on the input / output device 210 of the terminal 200, for example, a display program 330. The storage device 240 is used as a non-transitory tangible storage medium for storing 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 downloadable from a server. The display program 330 may be recorded and provided on the storage medium 1.

[0031] The arithmetic unit 220 performs various data processes for displaying the evaluation index 301 acquired from the agricultural information management device 100 by reading and executing the display program 330. The arithmetic unit 220 includes, for example, a central processing unit (CPU).

[0032] When the arithmetic unit 220 reads and executes the display program 330, it cooperates with the input / output device 210 to realize the display unit 250 as shown in FIG. 4. The display unit 250 acquires the evaluation index 301 from the agricultural information management device 100 and displays a display image including the evaluation index 301.

[0033] (Operation of the agricultural information management system) When the agricultural machine 30 shown in FIG. 1 stops, for example, when the engine stops, it transmits the operation information 302 to the agricultural information management device 100. When the agricultural machine 30 is operating, it may sequentially transmit the operation information 302 to the agricultural information management device 100.

[0034] When the arithmetic unit 120 of the agricultural information management device 100 receives the operation information 302 from the agricultural machine 30, it reads and executes the agricultural information management program 320 and starts the process shown in FIG. 5, which is an agricultural information management method. In step S110, the data storage unit 150 realized by the arithmetic unit 120 identifies the agricultural machine 30 that transmitted the operation information 302 based on the information regarding the transmission source of the operation information 302. The information representing the transmitting source agricultural machine 30 may be included in the operation information 302.

[0035] The data storage unit 150 may acquire information representing the work performed by the agricultural machine 30, such as information representing the harvest amount, the amount of pesticide spraying, the amount of fertilizer spraying, etc., from a measuring instrument not included in the agricultural information management system 1000. For example, the measuring instrument is provided in a harvesting work facility (such as a sugar factory). The measuring instrument measures the harvest amount of the harvested product brought into the harvesting work facility, and transmits information associating the measured harvest amount with the agricultural machine 30 that harvested the harvested product to the data storage unit 150. Also, the information representing the work performed by the agricultural machine 30 may be input by the user to the terminal 200 and transmitted from the terminal 200 to the data storage unit 150. The data storage unit 150 stores the acquired information in the operation information 302 in association with the agricultural machine 30.

[0036] In step S120, the evaluation index calculation unit 160 calculates each piece of information of the evaluation index 301 based on the operation information 302. The calculated evaluation index 301 is stored in the agricultural data 300 by the data storage unit 150. For example, the evaluation index calculation unit 160 calculates track information 303 representing the track along which the agricultural machine 30 has moved based on the position information included in the operation information 302.

[0037] Further, based on the operation information 302, the evaluation index calculation unit 160 classifies the state of the agricultural work machine 30 at each time into a plurality of working states. For example, when the engine is stopped, the state of the agricultural work machine 30 is classified as "off-duty". Also, when the engine is started and the position of the agricultural work machine 30 is not included in the field, the state of the agricultural work machine 30 is classified as "moving". Also, when the engine is started and the agricultural work machine 30 is moving at a position not included in the field, the state of the agricultural work machine 30 may be classified as "moving". When the engine is started and the agricultural work machine 30 is not moving, the state of the agricultural work machine 30 is classified as "idling". When the engine is started, the agricultural work machine 30 is moving at a position included in the field, and the agricultural work machine 30 is not working, for example, when the agricultural work machine 30 is turning, the state of the agricultural work machine 30 may be classified as "idling". Also, when the agricultural work machine 30 is working in the field, for example, when the mechanism performing the work is driven, the state of the agricultural work machine 30 is classified as "working".

[0038] Based on the position information of the agricultural work machine 30 and the field data 310, the evaluation index calculation unit 160 calculates the environmental information 305 of the field where the agricultural work machine 30 has been. For example, the evaluation index calculation unit 160 specifies the soil property where the agricultural work machine 30 has worked at each time. Specifically, the evaluation index calculation unit 160 specifies the field where the agricultural work machine 30 has worked based on the position information of the agricultural work machine 30. Based on the field data 310, the soil property of the specified field is acquired, and the evaluation index calculation unit 160 specifies the soil property where the agricultural work machine 30 has worked. Similarly, the evaluation index calculation unit 160 calculates the hardness of the soil, the lodging state of the crops, the degree of drainage, etc. of the field where the agricultural work machine 30 has been based on the position information of the agricultural work machine 30 and the field data 310. Also, the evaluation index calculation unit 160 acquires the precipitation amount of the area including the field from a server provided outside the agricultural information management system 1000. The evaluation index calculation unit 160 may acquire the precipitation amount that fell in a predetermined period before the agricultural work machine 30 performs the work based on the acquired precipitation amount.

[0039] Based on the position information of the agricultural work machine 30 and the period during which the agricultural work machine 30 performs operations, the evaluation index calculation unit 160 calculates the area information 307. For example, the evaluation index calculation unit 160 calculates the area surrounding the position information of the agricultural work machine 30 during the operation period as the working area. Further, the evaluation index calculation unit 160 may calculate the working area per unit time by dividing the working area by the operation period.

[0040] Furthermore, the evaluation index calculation unit 160 calculates the material information 308 based on the operation information 302. For example, the evaluation index calculation unit 160 calculates the total harvest amount by aggregating the harvest amounts associated with the position information. Also, the harvest amount per unit area may be calculated by dividing the total harvest amount by the working area. In addition, the evaluation index calculation unit 160 calculates the total pesticide spraying amount by aggregating the pesticide spraying amounts associated with the position information. Similarly, the evaluation index calculation unit 160 may calculate the total fertilizer spraying amount, the fertilizer spraying amount per unit area, and the pesticide spraying amount per unit area. Moreover, the evaluation index calculation unit 160 may obtain the consumed fuel from the operation information 302 and calculate the fuel consumption. Note that the agricultural information management device 100 may obtain the consumed fuel from a fuel dispenser connected to the network 20 or from an input by the user to the terminal 200.

[0041] In step S130, the output unit 170 outputs display information representing the evaluation index 301 to be displayed on the terminal 200. For example, the output unit 170 outputs the display information in response to a display operation input to the input / output device 210 of the terminal 200 for displaying the evaluation index 301. Specifically, when a display operation is input to the input / output device 210, the arithmetic unit 220 of the terminal 200 executes the display program 330. The display unit 250 realized by the arithmetic unit 220 generates a request signal for requesting the display information from the output unit 170 of the agricultural information management device 100 based on the display operation. For example, the request signal represents the display information to be displayed on the input / output device 210 among the evaluation indexes 301.

[0042] The output unit 170 calculates, according to a request signal from the display unit 250 of the terminal 200, among the evaluation indicators 301, the evaluation indicators 301 to be displayed on the input / output device 210. For example, when the evaluation indicator 301 for a certain period, such as one day, is to be displayed on the input / output device 210, the request signal includes a signal representing the period. The output unit 170 calculates the evaluation indicator 301 for the period represented by the request signal. For example, as shown in FIG. 2, when the yield included in the material information 308 among the evaluation indicators 301 is to be displayed, the output unit 170 acquires the yield for the period from the material information 308 of the corresponding agricultural working machine 30. The output unit 170 calculates the yield harvested by the agricultural working machine 30 during the period by aggregating the acquired yields.

[0043] Also, when the working area included in the area information 307 among the evaluation indicators 301 is to be displayed, the output unit 170 acquires the working area for the period from the area information 307 of the corresponding agricultural working machine 30. The output unit 170 calculates the working area on which the agricultural working machine 30 has worked during the period by aggregating the acquired working areas.

[0044] When the working time included in the operation time information 304 among the evaluation indicators 301 is to be displayed, the output unit 170 calculates the working time for the period during which work has been performed, for example, the working time corresponding to "working", from the operation time information 304 of the corresponding agricultural working machine 30.

[0045] Based on the calculated evaluation indicator 301, the output unit 170 calculates display information representing the evaluation indicator 301 according to the format to be displayed on the input / output device 210 of the terminal 200. For example, as shown in FIG. 2, the calculated evaluation indicator 301 displays a scale with the inside filled according to the value of the evaluation indicator 301 in the evaluation indicator display area 503. In this case, the display information is represented by the ratio of the evaluation indicator 301 to a predetermined value. Here, the predetermined value may be a value determined in advance. Also, when displaying the evaluation indicators 301 of a plurality of agricultural working machines 30, the predetermined value may be the maximum value of the displayed evaluation indicators 301. The ratio of the evaluation indicator 301 to the predetermined value may represent the number of scales to be filled.

[0046] The output unit 170 transmits the calculated display information to the display unit 250 of the terminal 200.

[0047] In step S140 shown in FIG. 5, the display unit 250 of the terminal 200 displays the display information output from the output unit 170 of the agricultural information management device 100. For example, as shown in FIG. 2, the display unit 250 displays a list image 500 representing the evaluation indexes 301 of a plurality of agricultural working machines 30. The list image 500 has device display areas 501 corresponding to the respective agricultural working machines 30. The evaluation indexes 301 of different agricultural working machines 30 are displayed in the first device display area 501-1, the second device display area 501-2, and the third device display area 501-3.

[0048] The list image 500 has an evaluation index display area 503 that visually represents the evaluation index 301 according to the ratio of the evaluation index 301 to a predetermined value. For example, the evaluation index display area 503 is divided into areas representing a plurality of scales, and the evaluation index 301 is represented by filling the scale according to the ratio. When the number of scales is 5 and the ratio of the evaluation index 301 is 20% or less, the evaluation index 301 is represented by filling the leftmost scale. When the ratio of the evaluation index 301 is 40% or less, the evaluation index 301 is represented by filling the two leftmost scales. When the ratio of the evaluation index 301 is 60% or less, the evaluation index 301 is represented by filling the three leftmost scales. When the ratio of the evaluation index 301 is 80% or less, the evaluation index 301 is represented by filling the four leftmost scales. When the ratio of the evaluation index 301 is greater than 80%, the evaluation index 301 is represented by filling all the scales. When the evaluation index 301 is displayed with reference to the maximum value of the displayed evaluation index 301, the display unit 250 represents the relative evaluation index 301 of the agricultural working machine 30 with less influence of external factors such as weather. Thereby, the user can relatively evaluate the agricultural working machine 30.

[0049] The evaluation index display area 503 determines a filling display form, such as color, hatching, etc., according to the value of the evaluation index 301. For example, the display form may be determined based on a comparison between the evaluation index 301 and a statistic of the evaluation index 301 in the agricultural working machine 30 being displayed, such as an average value. For example, the display form when the evaluation index 301 is greater than or equal to the average value may be different from the display form when the evaluation index 301 is less than the average value. The display form may be determined based on a comparison between the evaluation index 301 and its median value. Note that the display form may be determined based on a comparison between the evaluation index 301 and the statistic of the evaluation index 301 in all the agricultural working machines 30. Thereby, the user can easily grasp the agricultural working machine 30 with a relatively small evaluation index 301.

[0050] In addition, the list image 500 has a sort selection area 504 that changes the order of the device display areas 501 according to the value of the evaluation index 301. When the sort selection area 504 is selected, the display unit 250 changes the order of displaying the device display areas 501 according to the value of the evaluation index 301. For example, the display unit 250 changes the list image 500 so that the higher the evaluation index 301 corresponding to the sort selection area 504 where the position of each device display area 501 is selected, the higher it is displayed. Also, the display unit 250 may change the list image 500 so that the lower the evaluation index 301 corresponding to the sort selection area 504 where the position of each device display area 501 is selected, the higher it is displayed. For example, when the sort selection area 504 corresponding to the harvest amount per unit time is selected once, the display unit 250 changes the list image 500 so that the position of the device display area 501 corresponding to the agricultural working machine 30 with a larger harvest amount per unit time is displayed higher. When the sort selection area 504 corresponding to the harvest amount per unit time is selected again, the display unit 250 changes the list image 500 so that the position of the device display area 501 corresponding to the agricultural working machine 30 with a smaller harvest amount per unit time is displayed higher.

[0051] When the display unit 250 displays the list image 500 representing the display information, in step S150, it determines whether a display change operation for changing the display is input. The display change operation includes an index change operation for changing the displayed evaluation index 301, a device change operation for changing the displayed agricultural machine 30, a map display operation for representing the evaluation index 301 on the map, and the like. When a display change operation is input, the process returns to step S130 and is repeated.

[0052] For example, when the user inputs an index change operation to the input / output device 210, the display unit 250 generates a request signal representing the changed evaluation index 301 and transmits the generated request signal to the output unit 170 of the agricultural information management device 100. For example, the output unit 170 generates a request signal for adding evaluation indexes 301 such as the yield per unit area, the operation rate representing the ratio of the agricultural machine 30 performing the operation, the fuel consumption, and the yield per fuel consumption. When the output unit 170 receives the request signal, it executes the process of step S130 and repeats the process.

[0053] Further, when a device change operation for changing the agricultural work machine 30 is input, the display unit 250 generates a request signal representing the agricultural work machine 30 to be displayed. For example, in the list image 500 shown in FIG. 2, when the user selects the display selection area 510, the display unit 250 generates a request signal representing the agricultural work machine 30 corresponding to the selected display selection area 510. For example, the display selection area 510 represents the type of the agricultural work machine 30, such as a tractor, a transport vehicle, a harvester, etc. equipped with a working machine such as a transplanter, a seeder, a fertilizer applicator, a chemical sprayer, etc. Specifically, the second display selection area 510-2 may represent that the evaluation index 301 of the tractor is displayed. In this case, when the user selects the second display selection area 510-2, the display unit 250 generates a request signal representing the agricultural work machine 30 corresponding to the tractor. The generated request signal is transmitted to the output unit 170. When receiving the request signal, the output unit 170 executes the process of step S130 and repeats the process. In this case, the display information calculated by the output unit 170 may include the planting distance representing the distance of planting seedlings, the seedling planting amount representing the amount of planted seedlings, the seeding amount representing the amount of seeds sown in the field, the fertilizer application amount representing the amount of applied fertilizer, the chemical application amount representing the amount of applied chemicals, etc. In the list image 500 shown in FIG. 2, the first display selection area 510-1 represents the agricultural work machine 30 displayed in the list image 500.

[0054] Furthermore, when a state display operation representing a state classified into the working state of the agricultural work machine 30 during an aggregation period, for example, one day, such as working, idling, moving, and non-operating, is input to the display unit 250, the display unit 250 generates a request signal representing the working state of the agricultural work machine 30 at each time. The output unit 170 outputs display information representing the working state of the agricultural work machine 30 during the aggregation period based on the request signal in step S130. The display unit 250 displays the working state of the agricultural work machine 30 during the aggregation period based on the display information in step S140. For example, as shown in FIG. 6, the display unit 250 displays a working time display area 520 representing the working state of the agricultural work machine 30 at each time. The working time display area 520 represents the working state at each time during the aggregation period, for example, one day, and displays, for example, a bar graph. The working time display area 520 is marked with scales representing each time in the extending direction of the bar, and the working state at the corresponding time is distinguishable at the position of each scale. The working time display area 520 may represent only the preset set time, for example, the time during which work should be performed from 7:00 to 18:00. Thereby, the user can easily grasp the tendency of the agricultural work machine 30 to perform work.

[0055] In addition, the display unit 250 may display the ratio of the working states of the agricultural work machine 30 during an aggregation period, for example, one week. In this case, the display unit 250 generates a request signal representing the ratio of the working states during the aggregation period according to an input by the user. The output unit 170 outputs display information representing the ratio of the working states based on the request signal in step S130. The display unit 250 displays the ratio of the working states for each agricultural work machine 30 based on the display information in step S140. For example, as shown in FIG. 7, the display unit 250 displays a work ratio display area 525 representing the ratio of the working states of the agricultural work machine 30 during the aggregation period. The work ratio display area 525 represents the ratio of the working states during the aggregation period and displays, for example, a bar graph. The aggregation period may be limited to a preset time, for example, only the time when work should be performed from 7:00 to 18:00. For example, when the work ratio display area 525 represents the ratio of the working states in one week, it may represent the ratio of the working states during 77 hours from 7:00 to 18:00 within one week. Thereby, the user can easily grasp the ratio of the working states for each agricultural work machine 30. For example, the user can analyze the reason for the large fuel consumption of the agricultural work machine 30, such as the relatively large ratio during idling or the relatively large ratio during movement.

[0056] When the display unit 250 receives an input of a map display operation in which the user represents the evaluation index 301 on the map, it generates a request signal representing the evaluation index 301 to be represented on the map. In step S130, the output unit 170 outputs display information representing the evaluation index 301 and the map information corresponding to the evaluation index 301 based on the request signal. In step S140, the display unit 250 displays an image representing the evaluation index 301 on the map based on the display information. For example, as shown in FIG. 8, the display unit 250 represents on the map the work area 400 where the agricultural work machine 30 has performed work and the agricultural work machine position 410 representing the position of the agricultural work machine 30. Further, the display unit 250 displays the evaluation index 301 of the agricultural work machine 30 in the detailed information display area 411. The display unit 250 may display on the map the trajectory along which the agricultural work machine 30 has moved and the elevation contour lines. For example, the user can grasp whether the trajectory of the agricultural work machine 30 includes a position with a large inclination and analyze the evaluation index 301.

[0057] Also, as shown in FIG. 9, the display unit 250 may display a plurality of work areas 400 where a plurality of agricultural work machines 30 have performed work. The work areas 400 are displayed in a display form that can distinguish the corresponding agricultural work machines 30. For example, as shown in FIG. 2, the list image 500 has a device identification display area 502 for distinguishing the agricultural work machines 30 displayed in the device display area 501. The display form, for example, the color, displayed in the device identification display area 502 distinguishes the work area 400 where the corresponding agricultural work machine 30 has performed work from other work areas 400. For example, the first work area 400-1 where the agricultural work machine 30 corresponding to the first device display area 501-1 has performed work is displayed in the display form displayed in the first device identification display area 502-1. The second work area 400-2 where the agricultural work machine 30 corresponding to the second device display area 501-2 has performed work is displayed in the display form displayed in the second device identification display area 502-2. The third work area 400-3 where the agricultural work machine 30 corresponding to the third device display area 501-3 has performed work is displayed in the display form displayed in the third device identification display area 502-3. Thereby, the user can easily grasp the areas where each agricultural work machine 30 has performed work.

[0058] When the display unit 250 displays a plurality of work areas 400 where a plurality of agricultural work machines 30 have performed work, the output unit 170 outputs area information 307 that represents the plurality of work areas 400 in association with the agricultural work machines 30 that have performed the work. The display unit 250 displays the work areas 400 so as to be distinguishable according to the agricultural work machines 30 that have performed the work.

[0059] In step S150, when the user inputs an end display operation without inputting a display change operation, the process ends.

[0060] In this way, the agricultural information management system 1000 supports the user in accurately grasping the situation by displaying the work amount for each agricultural work machine 30. As a result, the user can easily perform analysis of agricultural work machine management and cultivation management.

[0061] For example, the agricultural information management system 1000 displays the material information 308, such as the harvest amount per unit time, in association with the environmental information 305, such as information regarding soil properties (the ratio of sandy and clayey soil, the lodging information of the crops in the field, etc.). As a result, the user can grasp the influence of the environment on the harvest work. Further, the agricultural information management system 1000 supports the user in determining the maintenance schedule of the agricultural work machine 30 by displaying the environmental information 305.

[0062] (Modification example) The configuration described in the embodiment is an example, and the configuration can be changed as long as the function is not impaired. The evaluation index 301 may be displayed in any format representing the relative size among the agricultural work machines 30, and may be displayed using a bar graph as shown in FIG. 10.

[0063] Also, the display selection area 510 may represent any group for the user to switch and analyze the display. For example, it may represent a plurality of teams. Each team includes a plurality of workers and represents the agricultural machinery 30 used by the workers within the team. For example, the first display selection area 510-1 represents displaying the evaluation indicators 301 of a plurality of agricultural machinery 30 used by the workers of the first team. The second display selection area 510-2 represents displaying the evaluation indicators 301 of a plurality of agricultural machinery 30 used by the workers of a second team different from the first team. Also, the display selection area 510 may represent displaying the evaluation indicators 301 of the agricultural machinery 30 classified according to the environmental information 305.

[0064] Also, the display selection area 510 may represent displaying the evaluation indicators 301 of the agricultural machinery 30 further classified into a plurality of groups. For example, the groups represented in the display selection area 510 may further classify the agricultural machinery 30 classified into teams according to the type of the agricultural machinery 30. In this case, by selecting the team to be displayed by the user and the type of the agricultural machinery 30 to be displayed, the evaluation indicators 301 of the corresponding agricultural machinery 30 are displayed.

[0065] The display form for displaying the evaluation indicator 301 in the evaluation indicator display area 503, such as color and hatching, may be determined to be distinguishable according to any conditions. For example, the display unit 250 may display the evaluation indicator 301 with a difference from the average value less than the threshold, the evaluation indicator 301 with a value less than the average value by more than the threshold, and the evaluation indicator 301 with a value greater than the average value by more than the threshold in a distinguishable display form. For example, when the evaluation indicator 301 is greater than the average value by more than the threshold, the evaluation indicator 301 is displayed in blue. When the difference between the evaluation indicator 301 and the average value is less than the threshold, the evaluation indicator 301 is displayed in yellow. When the evaluation indicator 301 is less than the average value by more than the threshold, the evaluation indicator 301 is displayed in red. Also, the display unit 250 may display the evaluation indicator 301 in a distinguishable display form according to the difference between the evaluation indicator 301 and the average value.

[0066] The embodiments and modification examples described above are merely examples, and the configurations described in each embodiment and modification example may be arbitrarily changed or / and arbitrarily combined within the range that does not inhibit the functions. Furthermore, if the necessary functions can be realized, some of the functions described in the embodiments and modification examples may be omitted. For example, the output unit 170 may be executed on the terminal 200. In this case, based on a request signal from the display unit 250 of the terminal 200, the data storage unit 150 of the agricultural information management device 100 outputs the corresponding evaluation index 301 to the output unit 170 of the terminal 200. Based on the evaluation index 301 acquired from the agricultural information management device 100, the output unit 170 of the terminal 200 calculates each evaluation index 301 for display and transmits the calculated evaluation index 301 to the display unit 250. Also, part or all of the agricultural information management device 100 may be executed by the terminal 200.

[0067] Also, the output unit 170 of the agricultural information management device 100 may generate various images displayed by the display unit 250, such as the list image 500 shown in FIG. 2, the map image representing the map information shown in FIG. 8, etc. In this case, the generated image is transmitted to the display unit 250 as display information. The display unit 250 displays the image represented by the display information.

[0068] Also, the agricultural information management system 1000 may display the evaluation index 301 on an external terminal that does not include the terminal 200 and is not included in the agricultural information management system 1000. Also, the display unit 250 of the terminal 200 may acquire map information from an external server not included in the agricultural information management system 1000 and display map information representing the evaluation index 301 on the map.
