[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 Figure 1, the agricultural information management system 1000 comprises an agricultural information management device 100 and a terminal 200. The agricultural information management device 100 is communicated with the terminal 200 and at least one or more agricultural machinery 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 harvesting machine 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) 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 more accurately grasp the working status of each agricultural work machine 30.

[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, it 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] The agricultural data 300 includes evaluation indicators 301 associated with each agricultural machine 30, as shown in Figure 3. The evaluation indicators 301 include operational information 302, track information 303, operating time information 304, environmental information 305, and work volume information 306. The operational information 302 represents each piece of information obtained from the agricultural machine 30. For example, the operational information 302 includes the speed of the agricultural machine 30, steering angle, engine load rate, etc.

[0021] The trajectory information 303 represents the trajectory of the agricultural machinery 30, calculated based on the operational information 302. The agricultural machinery 30 is equipped with a positioning device, such as a GNSS (Global Navigation Satellite System) receiver, and acquires position information representing its position at each time it moves. The trajectory information 303 is calculated based on the position information.

[0022] The operating time information 304 represents the time the agricultural machinery 30 was in operation, for example, the time from when the engine was started until it was stopped. The operating time information 304 also represents the time spent in one of several working states, such as working, stopped, moving, or not operating, based on the operating information 302. For example, the operating time information 304 represents the working state of the agricultural machinery 30 at each given time.

[0023] Environmental information 305 represents the condition of the field where the agricultural machinery 30 performed its work. For example, environmental information 305 represents the size of the field where the agricultural machinery 30 performed its work, the hardness of the soil, and the soil type, such as sandy or clayey, as represented by the soil particle size composition. Environmental information 305 may also represent the amount of rainfall in the field and the lodging status of the crops.

[0024] The work volume information 306 represents the amount of work performed by the agricultural machinery 30. For example, the work volume information 306 includes area information 307 relating to the area where work was performed, and material information 308 representing the amount of materials used and the harvest yield. The area information 307 includes, for example, the work area of ​​the area where work was performed, the work area performed per unit time, and the distance traveled by the transport vehicle to transport materials, etc. The material information 308 includes the harvest yield of crops, the amount of fertilizer and pesticides applied, the amount of crops planted, the amount of seeds sown, etc. The material information 308 may also include the amount of fuel consumed during the work. The material information 308 may also include the amount of materials used per unit area, the harvest yield per unit area, and the work area per unit of fuel consumption.

[0025] The field data 310 shown in Figure 1 represents information about the field where the agricultural machinery 30 operates. For example, the field data 310 includes the size of the field, the field area, the soil hardness in the field, the soil type in the field, the lodging status of crops in the field, and the amount of rainfall in the field. The field data 310 may also represent the degree of drainage, for example, whether it is a wet or 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 processing to calculate information representing the amount of work for each agricultural machine 30. For example, the arithmetic unit 120 includes a central processing unit (CPU).

[0027] The arithmetic unit 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 Figure 4. The data storage unit 150 stores 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 terminal 200 will be described. As shown in Figure 1, terminal 200 comprises an input / output device 210, an arithmetic unit 220, a communication device 230, and a storage device 240. Terminal 200 includes, for example, a computer, a tablet, a mobile phone, etc. Information for the arithmetic unit 220 to perform processing is input to the input / output device 210. The input / output device 210 also outputs the results of the processing performed by the arithmetic unit 220. The input / output device 210 includes various input and output devices, such as a keyboard, mouse, microphone, display, speaker, 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 information acquired from the agricultural information management device 100 to the computing device 220. It also transfers signals generated by the computing device 220 to the agricultural information management device 100. The communication device 230 includes various interfaces such as a NIC (Network Interface Card) and a USB (Universal Serial Bus).

[0030] The storage device 240 stores various data, such as a display program 330, for displaying the evaluation index 301 on the input / output device 210 of the terminal 200. 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 as a computer program product downloadable from a server. The display program 330 may also be provided recorded on storage medium 1.

[0031] The arithmetic unit 220 reads and executes the display program 330, performing various data processing to display the evaluation indicators 301 obtained from the agricultural information management device 100. 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 works in cooperation with the input / output device 210 to realize the display unit 250 as shown in Figure 4. The display unit 250 acquires the evaluation index 301 from the agricultural information management device 100 and displays a display image that includes the evaluation index 301.

[0033] (Operation of the agricultural information management system) When the agricultural machinery 30 shown in Figure 1 stops, for example when the engine is stopped, it transmits operation information 302 to the agricultural information management device 100. The agricultural machinery 30 may also transmit operation information 302 to the agricultural information management device 100 sequentially while it is in operation.

[0034] When the arithmetic unit 120 of the agricultural information management device 100 receives operation information 302 from the agricultural machinery 30, it reads and executes the agricultural information management program 320 and starts the process shown in Figure 5, which is the agricultural information management method. In step S110, the data storage unit 150 implemented by the arithmetic unit 120 identifies the agricultural machinery 30 that transmitted the operation information 302 based on information about the source of the operation information 302. Information representing the source agricultural machinery 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 machinery 30, such as harvest yield, pesticide application amount, and fertilizer application amount, from measuring instruments not included in the agricultural information management system 1000. For example, the measuring instrument may be installed in a harvesting facility (e.g., a sugar factory). The measuring instrument measures the harvest yield of the crops brought to the harvesting facility and transmits information relating the measured harvest yield and the agricultural machinery 30 that harvested the crops to the data storage unit 150. Alternatively, information representing the work performed by the agricultural machinery 30 may be input by the user into a 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, relating it to the agricultural machinery 30.

[0036] In step S120, the evaluation index calculation unit 160 calculates each piece of information for 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 representing the trajectory of the agricultural machinery 30 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 machinery 30 at each time point into several work states based on the operation information 302. For example, when the engine is stopped, the state of the agricultural machinery 30 is classified as "off-duty". Also, when the engine is started and the agricultural machinery 30 is not located in the field, the state of the agricultural machinery 30 is classified as "moving". Also, when the engine is started and the agricultural machinery 30 is moving in a location not included in the field, the state of the agricultural machinery 30 may be classified as "moving". When the engine is started and the agricultural machinery 30 is not moving, the state of the agricultural machinery 30 is classified as "idling". When the engine is started, the agricultural machinery 30 is moving in a location included in the field, and the agricultural machinery 30 is not working, for example, when the agricultural machinery 30 is turning, the state of the agricultural machinery 30 may be classified as "idling". Furthermore, when the agricultural machinery 30 is working in the field, for example, when the working mechanism is being driven, the state of the agricultural machinery 30 is classified as "working".

[0038] The evaluation index calculation unit 160 calculates environmental information 305 of the field where the agricultural machinery 30 worked, based on the location information of the agricultural machinery 30 and the field data 310. For example, the evaluation index calculation unit 160 identifies the soil type in which the agricultural machinery 30 worked at each time point. Specifically, the evaluation index calculation unit 160 identifies the field in which the agricultural machinery 30 worked, based on the location information of the agricultural machinery 30. Based on the field data 310, it obtains the soil type of the identified field and identifies the soil type in which the agricultural machinery 30 worked. Similarly, the evaluation index calculation unit 160 calculates the soil hardness, crop lodging status, and drainage degree of the field in which the agricultural machinery 30 worked, based on the location information of the agricultural machinery 30 and the field data 310. Furthermore, the evaluation index calculation unit 160 obtains rainfall data for the area, including the field, from a server located outside the agricultural information management system 1000. Based on the obtained rainfall data, the evaluation index calculation unit 160 may also obtain rainfall data for a predetermined period prior to when the agricultural machinery 30 performs its work.

[0039] The evaluation index calculation unit 160 calculates area information 307 based on the location information of the agricultural machinery 30 and the period during which the agricultural machinery 30 performed work. For example, the evaluation index calculation unit 160 calculates the area surrounding the location information of the agricultural machinery 30 during the period during which work was performed as the work area. Alternatively, the evaluation index calculation unit 160 may 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 material information 308 based on the operational information 302. For example, the evaluation index calculation unit 160 calculates the total harvest by aggregating the harvest amounts associated with location information. Alternatively, the harvest amount per unit area may be calculated by dividing the total harvest by the work area. The evaluation index calculation unit 160 also calculates the total amount of pesticides sprayed by aggregating the amount of pesticides sprayed associated with 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 pesticides sprayed per unit area. The evaluation index calculation unit 160 may also calculate fuel consumption by obtaining the fuel consumed from the operational information 302. The agricultural information management device 100 may obtain the consumed fuel from a refueling machine connected to the network 20, or from 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 display information in response to a display operation input to the input / output device 210 of the terminal 200 in order to display 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 implemented by the arithmetic unit 220 generates a request signal to request 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 from the evaluation index 301 to be displayed on the input / output device 210.

[0042] The output unit 170 calculates an evaluation index 301 from the evaluation index 301 to be displayed on the input / output device 210 in response to a request signal from the display unit 250 of the terminal 200. For example, when the input / output device 210 displays an evaluation index 301 for an aggregation period, for example, one day, the request signal includes a signal representing the aggregation period. The output unit 170 calculates the evaluation index 301 for the aggregation period represented by the request signal. For example, as shown in Figure 2, when the harvest amount included in the material information 308 is displayed among the evaluation index 301, the output unit 170 obtains the harvest amount for the aggregation period from the material information 308 of the corresponding agricultural machinery 30. The output unit 170 calculates the harvest amount harvested by the agricultural machinery 30 during the aggregation period by aggregating the obtained harvest amounts.

[0043] Furthermore, when the work area included in the area information 307 of the evaluation index 301 is displayed, the output unit 170 obtains the work area for the aggregation period from the area information 307 of the corresponding agricultural machinery 30. The output unit 170 calculates the work area performed by the agricultural machinery 30 during the aggregation period by aggregating the obtained work areas.

[0044] When the work time included in the operating time information 304 of the evaluation index 301 is displayed, the output unit 170 calculates the work time performed during the aggregation period, for example, the work time corresponding to "in operation," from the operating time information 304 of the corresponding agricultural machinery 30.

[0045] The output unit 170 calculates display information representing the calculated evaluation index 301, according to the format to be displayed on the input / output device 210 of the terminal 200, based on the calculated evaluation index 301. For example, as shown in Figure 2, the calculated evaluation index 301 is displayed in the evaluation index display area 503 with filled-in scales according to the value of the evaluation index 301. 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. Also, when displaying the evaluation index 301 of multiple agricultural machines 30, the predetermined value may be the maximum value of the displayed evaluation index 301. The ratio of the evaluation index 301 to the predetermined value may represent the number of filled-in scales.

[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 Figure 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 Figure 2, the display unit 250 displays a list image 500 representing the evaluation indicators 301 of multiple agricultural machinery 30. The list image 500 has a device display area 501 corresponding to each agricultural machinery 30. The first device display area 501-1, the second device display area 501-2, and the third device display area 501-3 display different evaluation indicators 301 of agricultural machinery 30.

[0048] The list image 500 has an evaluation index display area 503 that visually represents the evaluation index 301 according to its ratio to a predetermined value. For example, the evaluation index display area 503 is divided into areas representing multiple scales, and the evaluation index 301 is represented by filling in the scales according to its ratio. When there are 5 scales and the ratio of the evaluation index 301 is 20% or less, the evaluation index 301 is represented by filling in the leftmost scale. When the ratio of the evaluation index 301 is 40% or less, the evaluation index 301 is represented 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 represented 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 represented by filling in the four scales from the left. When the percentage of the evaluation index 301 is greater than 80%, the evaluation index 301 is represented by filling in all the divisions on the scale. The display unit 250 displays the relative evaluation index 301 of the agricultural machinery 30 that is less affected by external factors, such as weather, when the evaluation index 301 is displayed based on the maximum value of the displayed evaluation index 301. This allows the user to evaluate the agricultural machinery 30 relatively.

[0049] The evaluation index display area 503 determines a display format, such as color or hatching, for filling the scale according to the value of the evaluation index 301. For example, the display format may be determined based on a comparison between the evaluation index 301 and a statistical value of the evaluation index 301 for the displayed agricultural machinery 30, such as the average value. For example, the display format when the evaluation index 301 is above the average value may differ from the display format when the evaluation index 301 is below the average value. The display format may also be determined based on a comparison between the evaluation index 301 and its median value. Furthermore, the display format may be determined based on a comparison between the evaluation index 301 and a statistical value of the evaluation index 301 for all agricultural machinery 30. This allows the user to easily identify agricultural machinery 30 with a relatively small evaluation index 301.

[0050] Furthermore, 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 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 higher the evaluation index 301 corresponding to the selected sort selection area 504, the higher each device display area 501 is displayed. Alternatively, the display unit 250 may change the list image 500 so that the lower the evaluation index 301 corresponding to the selected sort selection area 504, the higher each device display area 501 is displayed. For example, when the sort selection area 504 corresponding to the yield per unit time is selected once, the display unit 250 changes the list image 500 so that the device display area 501 corresponding to the agricultural machinery 30 with a high yield per unit time is displayed at the top. When the sort selection area 504 corresponding to the yield 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 machinery 30 with a small yield per unit time is displayed at the top.

[0051] When the display unit 250 displays a list image 500 representing the display information, it determines in step S150 whether a display change operation to change the display has been input. Display change operations include indicator change operations to change the displayed evaluation indicators 301, device change operations to change the displayed agricultural machinery 30, and map display operations to represent the evaluation indicators 301 on a map. If a display change operation is input, the process returns to step S130 and is repeated.

[0052] For example, when a user inputs an indicator change operation to the input / output device 210, the display unit 250 generates a request signal representing the changed evaluation indicator 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 indicators 301 such as yield per unit area, operating rate representing the percentage of time the agricultural machinery 30 is working, fuel consumption, and yield per unit of fuel consumption. When the output unit 170 receives the request signal, it executes the process in step S130 and repeats the process.

[0053] Furthermore, when a device change operation to change the agricultural machinery 30 is input to the display unit 250, it generates a request signal representing the agricultural machinery 30 to be displayed. For example, in the list image 500 shown in Figure 2, when the user selects a display selection area 510, the display unit 250 generates a request signal representing the agricultural machinery 30 corresponding to the selected display selection area 510. For example, the display selection area 510 represents the type of agricultural machinery 30, such as a tractor, transport vehicle, or harvester equipped with implements such as a transplanter, seeder, fertilizer spreader, or pesticide sprayer. Specifically, the second display selection area 510-2 may represent the display of the tractor's evaluation index 301. 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 machinery 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 in step S130 and repeats the process. In this case, the display information calculated by the output unit 170 may include the planting distance, the amount of seedlings planted, the amount of seeds sown in the field, the amount of fertilizer applied, and the amount of pesticide applied. In the list image 500 shown in Figure 2, the first display selection area 510-1 represents the agricultural machinery 30 displayed in the list image 500.

[0054] Furthermore, when the display unit 250 receives a status display operation that represents the working status of the agricultural machinery 30 during an aggregation period, for example, one day, classified into states such as working, idle, moving, and non-operating, it generates a request signal representing the working status of the agricultural machinery 30 at each time point. In step S130, the output unit 170 outputs display information representing the working status of the agricultural machinery 30 during the aggregation period based on the request signal. In step S140, the display unit 250 displays the working status of the agricultural machinery 30 during the aggregation period based on the display information. For example, as shown in Figure 6, the display unit 250 displays a working time display area 520 that represents the working status of the agricultural machinery 30 at each time point. The working time display area 520 represents the working status at each time point during the aggregation period, for example, one day, and displays, for example, a bar graph. The working time display area 520 has scales representing each time point in the direction the bars extend, and the working status of the corresponding time point is distinguishably represented at the position of each scale. The work time display area 520 may only show the pre-set time, for example, the time when work should be performed from 7:00 to 18:00. This allows the user to easily understand the tendency of the agricultural machinery 30 to perform work.

[0055] The display unit 250 may also display the percentage of work status of the agricultural machinery 30 during an aggregation period, for example, one week. In this case, the display unit 250 generates a request signal representing the percentage of work status during the aggregation period in response to user input. In step S130, the output unit 170 outputs display information representing the percentage of work status based on the request signal. In step S140, the display unit 250 displays the percentage of work status for each agricultural machinery 30 based on the display information. For example, as shown in Figure 7, the display unit 250 displays a work percentage display area 525 representing the percentage of work status of the agricultural machinery 30 during the aggregation period. The work percentage display area 525 represents the percentage of work status 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 during which work should be performed from 7:00 to 18:00. For example, when the work percentage display area 525 represents the percentage of work status over one week, it may represent the percentage of work status during the 77 hours included from 7:00 to 18:00 within one week. This allows users to easily understand the proportion of work status for each agricultural machine 30. For example, users can analyze the reasons why an agricultural machine 30 consumes a lot of fuel, such as a relatively large proportion of idle time or a relatively large proportion of movement time.

[0056] When the user inputs a map display operation to show the evaluation index 301 on the 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 the map information corresponding to the evaluation index 301, based on the request signal. In step S140, the display unit 250 displays an image of the evaluation index 301 on the map based on the display information. For example, as shown in Figure 8, the display unit 250 displays the work area 400 where the agricultural machinery 30 performed work and the agricultural machinery position 410 representing the location of the agricultural machinery 30 on the map. The display unit 250 also displays the evaluation index 301 of the agricultural machinery 30 in the detailed information display area 411. The display unit 250 may also display the trajectory of the agricultural machinery 30 and elevation lines on the map. For example, a user can determine whether the trajectory of the agricultural machinery 30 includes a section with a steep incline and then perform an analysis of the evaluation index 301.

[0057] Furthermore, as shown in Figure 9, the display unit 250 may display multiple work areas 400 where multiple agricultural machinery 30 have performed work. The work areas 400 are displayed in a display format that allows for the distinction of the corresponding agricultural machinery 30. For example, as shown in Figure 2, the list image 500 has a device identification display area 502 for distinguishing the agricultural machinery 30 displayed in the device display area 501. The display format, such as color, displayed in the device identification display area 502 distinguishes the work area 400 where a corresponding agricultural machinery 30 has performed work from other work areas 400, as shown in Figure 9. For example, the first work area 400-1 where the agricultural machinery 30 corresponding to the first device display area 501-1 has performed work is displayed in the display format shown in the first device identification display area 502-1. The second work area 400-2 where the agricultural machinery 30 corresponding to the second device display area 501-2 has performed work is displayed in the display format shown in the second device identification display area 502-2. The third work area 400-3, where the agricultural machinery 30 working in the third device display area 501-3 has performed its work, is displayed in the same format as shown in the third device identification display area 502-3. This allows the user to easily understand the area in which each agricultural machinery 30 has performed its work.

[0058] When the display unit 250 displays multiple work areas 400 where multiple agricultural machinery 30 have performed work, the output unit 170 outputs area information 307 that associates the multiple work areas 400 with the agricultural machinery 30 that performed the work. The display unit 250 displays the work areas 400 in a way that allows them to be distinguished according to the agricultural machinery 30 that performed the work.

[0059] In step S150, if the user enters a display termination operation without entering a display change operation, the process is terminated.

[0060] In this way, the agricultural information management system 1000 supports users in accurately understanding the situation by displaying the workload for each agricultural machine 30. This allows users to easily perform agricultural machine management and cultivation management analysis.

[0061] For example, the agricultural information management system 1000 displays material information 308, such as yield per unit time, in association with environmental information 305, such as information on soil properties (ratio of sandy to clayey soil, lodging information of crops in the field, etc.). This allows the user to understand the impact of the environment on harvesting operations. Furthermore, by displaying the environmental information 305, the agricultural information management system 1000 assists the user in deciding on maintenance schedules for agricultural machinery 30.

[0062] (modified version) The configuration described in the embodiment is just one example, and the configuration can be changed as long as it does not impede the function. The evaluation index 301 may be displayed in any format that represents the relative size of the agricultural machinery 30, and may be displayed using a bar graph as shown in Figure 10.

[0063] Furthermore, the display selection area 510 may represent any group for the user to switch the display for analysis, for example, multiple teams. Each team includes multiple workers and represents the agricultural machinery 30 used by the workers in the team. For example, the first display selection area 510-1 represents displaying the evaluation indicators 301 for multiple agricultural machinery 30 used by workers in the first team. The second display selection area 510-2 represents displaying the evaluation indicators 301 for multiple agricultural machinery 30 used by workers in a second team, which is different from the first team. The display selection area 510 may also represent displaying the evaluation indicators 301 for agricultural machinery 30 classified according to environmental information 305.

[0064] Furthermore, the display selection area 510 may indicate that it will display evaluation indicators 301 for agricultural machinery 30 that have been further classified into multiple groups. For example, the groups displayed in the display selection area 510 may be agricultural machinery 30 classified into teams, and then further classified according to the type of agricultural machinery 30. In this case, by selecting the team to display and the type of agricultural machinery 30 to display, the evaluation indicators 301 for the corresponding agricultural machinery 30 will be displayed.

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

[0066] The embodiments and modifications described above are examples, and the configurations described in each embodiment and modification may be arbitrarily changed and / or combined as long as they do not impede the function. Furthermore, some of the functions described in the embodiments and modifications may be omitted if 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 the request signal from the display unit 250 of the terminal 200. The output unit 170 of the terminal 200 calculates each evaluation index 301 for display based on the evaluation index 301 obtained from the agricultural information management device 100 and transmits the calculated evaluation index 301 to the display unit 250. Alternatively, the terminal 200 may execute some or all of the functions of the agricultural information management device 100.

[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 Figure 2 and the map image representing map information shown in Figure 8. In this case, the generated images are transmitted to the display unit 250 as display information. The display unit 250 displays the images represented in the display information.

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