[0012] (Embodiment 1) An agricultural information 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, the agricultural information management system 1000 includes an agricultural information management device 100 and a terminal 200. The agricultural information management device 100 is communicatively connected to the terminal 200 and at least one agricultural machine 30 via a network 20, for example the Internet.

[0013] The agricultural work machines 30 perform agricultural work by moving within a farm field. The agricultural information management device 100 acquires operation information in the farm field from the agricultural work machines 30, and stores agricultural data 300 indicating the work area, planting amount, amount of pesticide applied, harvest amount, etc. based on the acquired operation information. The agricultural work machines 30 include, for example, tractors, rice planters, harvesters such as combines, and sprayers that spray pesticides such as drones. The agricultural work machines 30 may also include transport vehicles that transport harvested products, materials, etc.

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

[0015] The agricultural information management device 100 outputs information related to 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 showing the amount of work, such as the harvest amount, the work area, the amount of seedlings planted, and the amount of fertilizer applied, for each agricultural 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. This allows the user to grasp the work 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, a calculation 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 calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 outputs the results of the processing executed by the calculation device 120. The input / output device 110 includes various input devices and output devices, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, etc. 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 operation information acquired from the agricultural machine 30 to the arithmetic device 120. The communication device 130 also transfers signals generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0019] The storage device 140 stores various data for calculating information representing the amount of work for each agricultural machine 30, such as 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] 3, the agricultural data 300 includes evaluation indexes 301 associated with each agricultural work machine 30. The evaluation indexes 301 include operation information 302, trajectory information 303, operation time information 304, environmental information 305, and workload information 306. The operation information 302 represents each piece of information acquired from the agricultural work machine 30. For example, the operation information 302 includes the speed, steering angle, engine load factor, etc. of the agricultural work machine 30.

[0021] The trajectory information 303 indicates the trajectory along which the agricultural work machine 30 has moved, which is calculated based on the operation information 302. The agricultural work machine 30 is equipped with a positioning device, for example a GNSS (Global Navigation Satellite System) receiver, and acquires position information indicating the position at each time of movement. The trajectory information 303 is calculated based on the position information.

[0022] The operation time information 304 indicates the time during which the agricultural work machine 30 has been operating, for example, the time from when the engine starts to when it stops. The operation time information 304 also indicates a number of work states into which the state of the agricultural work machine 30 at each time point has been classified based on the operation information 302, for example, times during which the agricultural work machine 30 is working, stopped, moving, not operating, etc. For example, the operation time information 304 indicates the work state of the agricultural work machine 30 at each time point.

[0023] The environmental information 305 represents the state of the field where the agricultural work machine 30 has worked. For example, the environmental information 305 represents the size of the field where the agricultural work machine 30 has worked, the hardness of the soil, and the soil texture such as sand or clay represented by the soil particle size composition. The environmental information 305 may also represent the amount of precipitation in the field, the lodging state of the crops, and the like.

[0024] The work amount information 306 indicates the amount of work performed by the agricultural work machine 30. For example, the work amount information 306 includes area information 307 related to the area where the work was performed, and material information 308 indicating the amount of materials used in the work and the harvest amount. The area information 307 includes, for example, the work area of ​​the area where the work was performed, the work area where the work was performed per unit time, and the travel distance traveled by the transport vehicle to transport materials and the like. The material information 308 includes the yield of the harvested crops, the amount of fertilizer and pesticides sprayed, the amount of crops planted, the amount of seeds sown, and the like. The material information 308 may also include the amount of fuel consumed in the work. The material information 308 may also include the amount of materials used per unit area, the harvest amount per unit area, and the work area per fuel consumption amount.

[0025] 1 represents information about a field in which the agricultural work machine 30 works. For example, the field data 310 includes the size of the field, the area of ​​the field, the hardness of the soil in the field, the soil texture in the field, the lodging state of crops in the field, the amount of precipitation in the field, etc. The field data 310 may also represent the degree of drainage, for example, whether the field is wet or dry.

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

[0027] The arithmetic device 120 reads and executes the agricultural information management program 320, thereby realizing a data storage unit 150, an evaluation index calculation unit 160, and an output unit 170, as shown in Fig. 4. The data storage unit 150 stores agricultural data 300. The evaluation index calculation unit 160 calculates various information included in an evaluation index 301 based on the agricultural data 300. The output unit 170 outputs display information indicating 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, a calculation device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the calculation device 220 to execute processing is input to the input / output device 210. In addition, the input / output device 210 outputs the result of the calculation device 220 executing the processing. 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, and the like.

[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 information acquired from the agricultural information management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the agricultural information management device 100. The communication device 230 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[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 in 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 provided by being recorded in a storage medium 1.

[0031] The arithmetic device 220 reads and executes the display program 330 to perform various data processing for displaying the evaluation index 301 acquired from the agricultural information management device 100. The arithmetic device 220 includes, for example, a central processing unit (CPU; Central Processing Unit) and the like.

[0032] When the arithmetic device 220 reads and executes the display program 330, it cooperates with the input / output device 210 to realize a 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) 1, when it stops, for example when its engine is stopped, it transmits operation information 302 to the agricultural information management device 100. The agricultural machine 30 may successively transmit the operation information 302 to the agricultural information management device 100 while it is operating.

[0034] When the calculation device 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 agricultural information management method shown in Fig. 5. In step S110, the data storage unit 150 realized by the calculation device 120 identifies the agricultural machine 30 that transmitted the operation information 302, based on information related to the source of the operation information 302. Information indicating the 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 work machine 30, such as information representing the harvest volume, the amount of pesticide sprayed, the amount of fertilizer sprayed, etc., from a measuring device not included in the agricultural information management system 1000. For example, the measuring device is provided in a harvest work facility (e.g., a sugar factory). The measuring device measures the harvest volume of the harvested crop brought to the harvest work facility, and transmits information associating the measured harvest volume with the agricultural work machine 30 that harvested the crop to the data storage unit 150. In addition, information representing the work performed by the agricultural work machine 30 may be input by a 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 work 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 trajectory information 303 that indicates the trajectory along which the agricultural machine 30 has moved, based on the position information included in the operation information 302.

[0037] Furthermore, the evaluation index calculation unit 160 classifies the state of the agricultural work machine 30 at each time into a plurality of work states based on the operation information 302. For example, when the engine is stopped, the state of the agricultural work machine 30 is classified as "off-duty". Furthermore, 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". Furthermore, 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". Furthermore, when the agricultural work machine 30 is performing work in a field, for example when a mechanism that performs the work is driving, the state of the agricultural work machine 30 is classified as "working."

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

[0039] The evaluation index calculation unit 160 calculates the area information 307 based on the position information of the agricultural work machine 30 and the period during which the agricultural work machine 30 performed work. For example, the evaluation index calculation unit 160 calculates the area surrounding the position information of the agricultural work machine 30 during the period during which work was performed as the work area. The evaluation index calculation unit 160 may also calculate the work area per unit time by dividing the work area by the period during which work was performed.

[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 tallying up the harvest amount associated with the location information. Also, the harvest amount per unit area may be calculated by dividing the total harvest amount by the work area. Also, the evaluation index calculation unit 160 calculates the total amount of pesticide sprayed by tallying up the amount of pesticide sprayed associated with the location information. Similarly, the evaluation index calculation unit 160 may calculate the total amount of fertilizer sprayed, the amount of fertilizer sprayed per unit area, and the amount of pesticide sprayed per unit area. Also, the evaluation index calculation unit 160 may obtain the fuel consumed from the operation information 302 and calculate the fuel consumption amount. Note that the agricultural information management device 100 may obtain the consumed fuel from a fuel tanker connected to the network 20, or may obtain the consumed fuel from an input by a 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 to display the evaluation index 301. Specifically, when a display operation is input to the input / output device 210, the arithmetic device 220 of the terminal 200 executes a display program 330. The display unit 250 realized by the arithmetic device 220 generates a request signal for requesting 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 display information of the evaluation index 301 to be displayed on the input / output device 210.

[0042] In response to a request signal from the display unit 250 of the terminal 200, the output unit 170 calculates the evaluation index 301 to be displayed on the input / output device 210, among the evaluation indexes 301. For example, when the evaluation index 301 for a collection period, for example, one day, is displayed on the input / output device 210, the request signal includes a signal representing the collection period. The output unit 170 calculates the evaluation index 301 for the collection period represented by the request signal. For example, as shown in FIG. 2, when the harvest amount included in the material information 308 of the evaluation index 301 is displayed, the output unit 170 acquires the harvest amount for the collection period from the material information 308 of the corresponding agricultural work machine 30. The output unit 170 calculates the harvest amount harvested by the agricultural work machine 30 during the collection period by tallying up the acquired harvest amounts.

[0043] Furthermore, when a work area included in the area information 307 of the evaluation index 301 is displayed, the output unit 170 acquires the work area during the aggregation period from the area information 307 of the corresponding agricultural work machine 30. The output unit 170 calculates the work area on which the agricultural work machine 30 performed work during the aggregation period by aggregating the acquired work areas.

[0044] When the working time included in the operation time information 304 of the evaluation index 301 is displayed, the output unit 170 calculates the working time during which work was performed during the aggregation period from the operation time information 304 of the corresponding agricultural machine 30, for example, the working time corresponding to “working”.

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

[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 display information output from the output unit 170 of the agricultural information management device 100. For example, the display unit 250 displays a list image 500 showing the evaluation indexes 301 of a plurality of agricultural machines 30, as shown in Fig. 2. The list image 500 has device display areas 501 corresponding to each agricultural machine 30. The evaluation indexes 301 of different agricultural 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 index list image 500 has an evaluation index display area 503 that visually displays 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 that display a plurality of scales, and the evaluation index 301 is displayed by filling in the scales according to its ratio. When the number of scales is five and the ratio of the evaluation index 301 is 20% or less, the evaluation index 301 is displayed by filling in the leftmost scale. When the ratio of the evaluation index 301 is 40% or less, the evaluation index 301 is displayed by filling in the two scales from the left. When the ratio of the evaluation index 301 is 60% or less, the evaluation index 301 is displayed by filling in the three scales from the left. When the ratio of the evaluation index 301 is 80% or less, the evaluation index 301 is displayed by filling in the four scales from the left. When the proportion of the evaluation index 301 is greater than 80%, the evaluation index 301 is displayed with all the scales filled in. When the evaluation index 301 is displayed based on the maximum value of the displayed evaluation index 301 as the reference, the display unit 250 displays the relative evaluation index 301 of the agricultural work machine 30 that is less affected by external factors, for example, weather, etc. This allows the user to evaluate the agricultural work machine 30 relatively.

[0049] The evaluation index display area 503 determines the display form for filling in the scale, for example, 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 statistical amount of the evaluation index 301 for the displayed agricultural work machine 30, for example, an average value. For example, the display form when the evaluation index 301 is equal to or greater than 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 a statistical amount of the evaluation index 301 for all agricultural work machines 30. This enables the user to easily identify agricultural work machines 30 with relatively small evaluation indexes 301.

[0050] The list image 500 also 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 in which the device display areas 501 are displayed according to the value of the evaluation index 301. For example, the display unit 250 changes the list image 500 so that the position of each device display area 501 corresponding to the selected sort selection area 504 is displayed higher as the evaluation index 301 corresponding to the selected sort selection area 504 is larger. The display unit 250 may also change the list image 500 so that the position of each device display area 501 corresponding to the selected sort selection area 504 is displayed higher as the evaluation index 301 corresponding to the selected sort selection area 504 is smaller. 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 machine 30 with the larger harvest amount per unit time is displayed higher. When the sorting selection area 504 corresponding to the harvest volume per unit time is selected again, the display unit 250 changes the list image 500 so that the position of the equipment display area 501 corresponding to the agricultural machine 30 with the smallest harvest volume per unit time is displayed at the top.

[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 has been input. Display change operations include an index change operation for changing the displayed evaluation index 301, an equipment change operation for changing the displayed agricultural machine 30, a map display operation for displaying the evaluation index 301 on a map, etc. When a display change operation is input, the process returns to step S130 and is repeated.

[0052] For example, when a user inputs an index change operation to the input / output device 210, the display unit 250 generates a request signal indicating 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 to add evaluation indexes 301 such as the harvest volume per unit area, the operation rate indicating the proportion of the agricultural machine 30 performing work, the fuel consumption, and the harvest volume per fuel consumption. Upon receiving the request signal, the output unit 170 executes the process of step S130 and repeats the process.

[0053] Furthermore, 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, when the user selects the display selection area 510 in the list image 500 shown in FIG. 2, 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, for example, a tractor equipped with a work machine such as a transplanter, a seeding machine, a fertilizer applicator, or a chemical sprayer, a transporter, or a harvester. 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 the output unit 170 receives the request signal, it executes the process of step S130 and repeats the process. In this case, the display information calculated by the output unit 170 may include a planting distance indicating the distance the seedlings were planted, a seedling planting amount indicating the amount of seedlings planted, a seeding amount indicating the amount of seeds sown in the field, a fertilizer application amount indicating the amount of fertilizer applied, a pesticide application amount indicating the amount of pesticide applied, etc. In the list image 500 shown in FIG. 2, the first display selection area 510-1 indicates the agricultural work machine 30 displayed in the list image 500.

[0054] Furthermore, when a state display operation is input to indicate the working state of the agricultural work machine 30 during a counting period, for example, one day, for example, a state classified as working, idling, moving, and not operating, the display unit 250 generates a request signal indicating the working state of the agricultural work machine 30 at each time. In step S130, the output unit 170 outputs display information indicating the working state of the agricultural work machine 30 during the counting period based on the request signal. In step S140, the display unit 250 displays the working state of the agricultural work machine 30 during the counting period based on the display information. For example, as shown in FIG. 6, the display unit 250 displays a working time display area 520 indicating the working state of the agricultural work machine 30 at each time. The working time display area 520 indicates the working state at each time during the counting period, for example, one day, and displays, for example, a bar-shaped graph. In the working time display area 520, scales indicating each time are provided in the direction in which the bars extend, and the working state at the corresponding time is distinguishably indicated at the position of each scale. The work time display area 520 may display only a preset set time, for example, a time when work should be performed from 7:00 to 18:00. This allows the user to easily grasp the tendency of the agricultural work machine 30 to perform work.

[0055] Furthermore, the display unit 250 may display the proportion of the working state of the agricultural work machine 30 in a counting period, for example, one week. In this case, the display unit 250 generates a request signal representing the proportion of the working state in the counting period in response to an input by the user. In step S130, the output unit 170 outputs display information representing the proportion of the working state based on the request signal. In step S140, the display unit 250 displays the proportion of the working state for each agricultural work machine 30 based on the display information. For example, as shown in FIG. 7, the display unit 250 displays a work proportion display area 525 representing the proportion of the working state of the agricultural work machine 30 in the counting period. The work proportion display area 525 represents the proportion of the working state in the counting period, and displays, for example, a bar graph. The counting period may only cover a preset set time, for example, a time from 7:00 to 18:00 when work should be performed. For example, when representing the proportion of the working state in one week, the work proportion display area 525 may represent the proportion of the working state in 77 hours included in the period from 7:00 to 18:00 in one week. This enables the user to easily grasp the proportion of the working state for each agricultural work machine 30. For example, the user can analyze the cause of high fuel consumption of the agricultural work machine 30, such as the fact that the proportion during idling is relatively high, or the proportion during movement is relatively high, etc.

[0056] When the user inputs a map display operation to display the evaluation index 301 on a map, the display unit 250 generates a request signal representing the evaluation index 301 to be displayed on the map. In step S130, the output unit 170 outputs display information representing the evaluation index 301 and 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 a map based on the display information. For example, as shown in FIG. 8, the display unit 250 displays on the map a work area 400 in which the agricultural work machine 30 has performed work, and an agricultural work machine position 410 representing the position of the agricultural work machine 30. In addition, 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 track along which the agricultural work machine 30 has moved, or an elevation line. For example, the user can analyze the evaluation index 301 by determining whether the trajectory of the agricultural machine 30 includes a position with a large incline.

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

[0058] When the display unit 250 displays a plurality of work areas 400 in which 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 performed the work. The display unit 250 displays the work areas 400 in a manner that allows distinction according to the agricultural work machines 30 that performed the work.

[0059] If the user inputs a display termination operation in step S150 without inputting a display change operation, the process ends.

[0060] In this way, the agricultural information management system 1000 supports the user in accurately understanding the situation by displaying the amount of work for each agricultural machine 30. This enables the user to easily analyze agricultural machine management and cultivation management.

[0061] For example, the agricultural information management system 1000 displays material information 308, such as the harvest volume per unit time, in association with environmental information 305, such as information on soil type (the ratio of sand to clay, information on lodging of crops in the field, etc.). This allows the user to understand the impact of the environment on harvesting work. Furthermore, by displaying the environmental information 305, the agricultural information management system 1000 supports the user in determining a maintenance schedule for the agricultural machine 30.

[0062] (Modification) The configurations described in the embodiments are merely examples, and the configurations can be changed as long as the functions are not impaired. The evaluation index 301 may be displayed in any format that represents the relative size between the agricultural machines 30, and may be displayed using a bar graph as shown in Fig. 10.

[0063] Furthermore, the display selection area 510 may represent any group for the user to switch between displays for analysis, and may represent, for example, a plurality of teams. Each team includes a plurality of workers and represents the agricultural work machines 30 used by the workers in the team. For example, the first display selection area 510-1 represents display of the evaluation indexes 301 of a plurality of agricultural work machines 30 used by workers of a first team. The second display selection area 510-2 represents display of the evaluation indexes 301 of a plurality of agricultural work machines 30 used by workers of a second team different from the first team. Furthermore, the display selection area 510 may represent display of the evaluation indexes 301 of the agricultural work machines 30 classified according to the environmental information 305.

[0064] Furthermore, the display selection area 510 may display the evaluation indexes 301 of agricultural machines 30 that are further classified into a plurality of groups. For example, the groups displayed in the display selection area 510 may be obtained by further classifying the agricultural machines 30 that are classified into teams according to the type of agricultural machine 30. In this case, the user selects the team to be displayed and the type of agricultural machine 30 to be displayed, and the evaluation index 301 of the corresponding agricultural machine 30 is displayed.

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

[0066] The above-described embodiment and modified examples are merely examples, and the configurations described in each embodiment and modified example may be arbitrarily modified and / or arbitrarily combined as long as the functions are not impaired. Furthermore, some of the functions described in the embodiment and modified examples may be omitted as long as the necessary functions can be realized. For example, the output unit 170 may be executed by the terminal 200. In this case, 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 a request signal from the display unit 250 of the terminal 200. The output unit 170 of the terminal 200 calculates each evaluation index 301 to be displayed based on the evaluation index 301 acquired from the agricultural information management device 100, and transmits the calculated evaluation index 301 to the display unit 250. In addition, a part or all of the agricultural information management device 100 may be executed by the terminal 200.

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

[0068] Furthermore, the agricultural information management system 1000 may not include the terminal 200, and may display the evaluation index 301 on an external terminal not included in the agricultural information management system 1000. Furthermore, the display unit 250 of the terminal 200 may obtain map information from an external server not included in the agricultural information management system 1000, and display the map information showing the evaluation index 301 on a map.
