Description

[Technical field]

[0001] The present invention relates to an agricultural work support system that provides a work plan in a farm field for agricultural work that is time-limited. [Background technology]

[0002] In agriculture, there are some tasks whose effectiveness is limited due to the growth of crops and weeds. In addition, large-scale agricultural corporations in mountainous areas must manage many plots of land, each with different conditions, even if they are the same crop and variety, because they are located on sloping land and each plot is small. For this reason, it is necessary to define agricultural information utilization methods that contribute to the operation planning of appropriate work by collecting and utilizing work information for each individual field, and further, to manage the common provision of data in order to operate these, so that effective field management work can be carried out despite uncertainties such as delays in work due to weather and changes in crop development due to weather. In agricultural work, it is common to indicate the optimum time for work based on the developmental stage of a plant, and this is used as a method to express the optimum time for work regardless of the weather conditions or cultivation season of each region. In addition, research into methods for predicting the developmental stage of a plant based on the sowing date or a specific known developmental stage using a numerical model that incorporates weather data and other factors has been conducted for many crops such as rice, wheat, and soybeans. Specifically, research is being conducted into the use of this method for predicting the flowering period of wheat, which serves as a guide for the optimum time to control Fusarium head blight in wheat, and technology is being developed to indicate the optimum time for work based on this data. Systems that calculate and display the flowering period according to the sowing date on a website are also available. Incidentally, Patent Document 1 discloses a farm work support device having farm field information and a spraying plan creation unit. Moreover, Patent Document 2 discloses a support system for planning agricultural work in multiple fields. Furthermore, Patent Document 3 discloses a system that creates a plan for carrying out another task by another machine in the same farm field, based on data obtained during the task by the machine. Furthermore, Patent Document 4 discloses a device that outputs the name of a pesticide and the date of application of the pesticide based on the predicted period of pest occurrence.

[0004] For the control of Fusarium head blight in wheat, the sowing date and cultivation area are specified, and the flowering of wheat is predicted using a weather model, with the optimum control period being one week after flowering, for the control of difficult-to-control weeds in soybeans, the optimum control periods are the 2-leaf and 5-leaf stages, and for the control of barnyard grass in dry-sown rice, the optimum control period is when the barnyard grass has 5 leaves, but the information presented is the date indicating the optimum period.However, a system that only provides dates can be a guide for the work period for agricultural producers who have accumulated farmland and need to manage many fields, but it is not possible to grasp the corresponding date and location (field). In other words, systems that provide only dates have problems such as not storing the location (field) and the date related to that location (variety and sowing date or flowering period calculated therefrom) in association with each other; while the location (field) and the date when sowing was done at that location are stored in association with each other, the predicted flowering period, which is affected by weather conditions (which differ for each field), is not stored in association with the location; and it is not possible to understand the relationship between the requirements of the location (field) (for example, position, area, field shape, etc.) and the date. Therefore, this information is not sufficient at the stage of actually using specific machinery, allocating personnel, and proceeding with specific work. In proceeding with specific work, it is necessary to specify the field and work time, specify the work method, and then clarify the feasibility of the work.

[0005] Therefore, an object of the present invention is to provide an agricultural work support system capable of calculating a work plan for a multi-plot field, particularly in a hilly and mountainous region. [Means for solving the problem]

EXAMPLES

[0020] An agricultural work support system according to an embodiment of the present invention will now be described. FIG. 1 is a flow diagram showing the farm work support system according to this embodiment. The agricultural work support system of this embodiment provides work plans in the field for agricultural work that is limited to a certain period of time, and appropriately uses the data stored in the field information database 11, the cultivation information database 12, the cultivated crop information database 13, the work machine / work method information database 14, and the meteorological information database 15, and stores data necessary for the agricultural work support system in the database 10.

[0021] In the field information database 11, a field identification code is assigned to each field, and the position coordinates of the center point and representative points, as well as the field area and field shape are stored for each field. The representative point is, for example, the position where the work machine is brought in and out, and using the position where the work machine is brought in and out as the representative point in the field is suitable for calculating the movement route. For the field shape, a field map using at least two-dimensional data is suitable. The cultivation information database 12 stores the type, variety, sowing date (planting date) of the crop in each field, and the date of the actual pest control work. It is linked to the data in the field information database 11 by the field identification code. It is preferable to have past cultivation performance data for each field, but at least for the work target fields targeted by the agricultural work support system, the type, variety, sowing date (planting date), and pest control date are stored for crops that are to be newly planted or that have already been planted and are being cultivated. The cultivated crop information database 13 stores growth and cultivation models for each type and variety of crop. The work machine / work method information database 14 stores the type, number, and work method of work machines that can be used for a task. The work method includes the work item name, work efficiency by item, the number of workers, necessary materials, and the like as elements. The weather information database 15 stores past weather data records and future weather forecasts. It is preferable that the database 10 stores the planned optimum work timings for the cultivated crops calculated using the sowing dates stored in the cultivation information database 12 and the weather data stored in the weather information database 15, and the growth and cultivation models stored in the cultivated crop information database 13. Storing the planned optimum work timings in the database 10 in advance for each farm field makes it easy to extract agricultural works that have optimum work timings.

[0022] In the farm work support system according to this embodiment, the computer performs the following processes. In the optimum timing calculation step 21, target fields for work that need to be performed are extracted, and the optimum timing for work is calculated for each target field. The optimum timing for work for each field is calculated by calculating the scheduled start date when agricultural work such as pest control work can be performed, and the scheduled final date when agricultural work such as pest control work can be performed before it becomes impossible. For example, the optimum time for work in controlling Fusarium head blight in wheat is one week from the flowering stage, with the planned start date for work being possible being the flowering stage and the planned final date for work being possible being six days after the flowering stage. Incidentally, the "flowering stage" of wheat is the day when approximately 50% of the ears in the field have flowered, and if even one ear has a flower in bloom, that ear is considered to be flowering. Therefore, the flowering stage refers to a specific day rather than a period of time. In addition, for the control of difficult-to-control weeds in soybeans, the optimum times for control (optimum time for work) are the 2-leaf and 5-leaf stages of the soybean crop, and for the control of barnyard grass in dry-sown rice, the optimum time for control (optimum time for work) is until the barnyard grass reaches the 5-leaf stage. In the optimal calculation step 21, it is preferable to use meteorological information for calculation. If weather forecast data is available for the period from the scheduled start date to the scheduled final date, the weather forecast data is used. If weather forecast data is not available, past weather data is used. Whether to use weather forecast data or past weather data can also be calculated based on whether the scheduled start date or the scheduled final date is within a predetermined number of days from the output date of the work plan. For example, forecast values ​​provided by the mesh agricultural meteorological data system (The Agro-Meteorological Grid Square Data, NARO) can be used as the weather forecast data. Note that the forecast values ​​provided by the system are for 26 days, so from the 27th day onwards, when there are no forecast values, average values ​​using past weather data are used as forecast values.

[0023] In the agricultural work extraction step 22, agricultural works that have an optimum period within a predetermined period are extracted. Here, agricultural works that have an optimum period include, for example, pest control work, top dressing, water filling in paddy fields, harvesting, etc., which occur from sowing or planting to harvesting and have an optimum period for work. The predetermined period is a period from the present, for example, one month or three months from the present. The extraction can be performed, for example, using the type, variety, and sowing date (planting date) of the crop in each field stored in the cultivation information database 12, and the growth and cultivation model for each type and variety of the crop stored in the cultivated crop information database 13. If the database 10 has previously stored the scheduled optimum period for work for the cultivated crop in each field, this scheduled optimum period can be used.

[0024] In the optimum timing list display step 23, agricultural works that have optimum times for work are displayed. In step 23 of displaying a list of suitable work times, by displaying the work type of agricultural work that has an appropriate work time and at least one of the scheduled start date and the scheduled final date for work regarding the appropriate work time, the appropriate work time can be grasped together with the work type, making it easy to create a work schedule. In addition, in the optimum timing list display step 23, by displaying the number of fields and total field area of ​​work target fields that have the same optimum timing for the same work type, the number of fields and total field area can be grasped by optimum timing, which makes it easy to grasp the overall situation, particularly in fields with multiple plots. To this end, the computer adds up the number of fields and total field area of ​​work target fields that have the same optimum timing for the same work type. In addition, in the optimum timing list display step 23, by displaying the number of fields and the total area of ​​fields for each optimum timing for work target fields with the same work type but different optimum timings, work target fields with different optimum timings can also be grasped for each optimum timing for work target fields, making it easier to grasp the overall situation, particularly in the case of cultivation of multiple varieties in multiple plots of fields or cultivation with different sowing dates. To this end, the computer adds up the number of fields and the total area of ​​fields for each optimum timing for work target fields with the same work type but different optimum timings. In addition, in the optimum timing list display step 23, for work target fields with the same optimum timing for different work types, the number of fields and the total field area are displayed for each optimum timing for each work type, making it possible to grasp work target fields with different work types for each optimum timing, and making it easy to grasp the overall situation, particularly when cultivating multiple items in a multi-plot field. To this end, the computer adds up the number of fields and the total field area for each optimum timing for each work type for work target fields with the same optimum timing for different work types. In the optimal time list display step 23, the user is prompted to select an agricultural work. That is, the user can select some of the agricultural works displayed in the optimal time list display step 23 (S24). The selection of the agricultural work can be performed by inputting an input in the check box shown in FIG. 4. The computer extracts farm field information on the farm work selected in the work selection step 24 (S25).

[0025] If the user wishes to check the field (Yes in S26), the computer displays a field map (S27). In the farm field map display step 27, the extracted work target farm field is displayed as a farm field map. If the user does not need to check the field (No in S26) and wishes to calculate a work plan (Yes in S28), the computer prompts the user to input conditions (S29). In the condition input step 29, the computer prompts the user to input the start date or end date of the farm work, and the farm work method. When conditions are input in the condition input step 29, a process of calculating a work plan for the extracted work target field is performed in the work plan calculation step 30. For the work plan calculated in the work plan calculation step 30, if the work start date is input as a condition, the work end date is displayed, and if the work end date is input as a condition, the work start date is displayed (S31). If the calculated work end date is later than the scheduled available work end date, or if the calculated work start date is earlier than the scheduled available work start date, or if it is the current day (the date the work plan was output) or a day earlier than yesterday, it is determined to be ineligible (No in S32), and a warning is displayed (S33) and the user is prompted to re-enter the conditions (S29). If the calculated work end date is before the scheduled workable end date, or if the calculated work start date is after the scheduled workable start date, it is determined to be eligible (Yes in S32). If the user wishes to display the work plan map (Yes in S34), the computer displays the work plan map (S35). In the work plan map display step 35, the work plan calculated in the work plan calculation step 30 is displayed.

[0026] If the user does not need to display the work plan map (No in S34), the process ends with the work plan saved (S36). If the calculation of the work plan is not requested by the user (No in S28), the computer ends the process without prompting the user to input conditions (S37).

[0027] FIG. 2 is a flow diagram showing the work plan calculation process (S30) in the farm work support system. The process of calculating a daily work plan is carried out from S41 to S57.

[0028] In step 41 of calculating the fixed outside-field work time, the work required for each day, such as preparation before the start of work that can be predicted in advance and cleaning after work is completed, is calculated. The fixed outside-field work time is calculated according to the type and number of working machines to be used and the number of machines, with standard times set in advance according to the type and number of working machines. Here, the standard times set in advance are stored in the working machine / working method information database 14 of the database 10 and are called up as necessary.

[0029] In the field information extraction step 42, at least the field position coordinates and the field area are extracted from the field information database 11 as field information for the work target fields where the agricultural work selected by the user in S25 will be carried out.

[0030] The position coordinates of the hangar for the work machine are set in the start point setting step 43. When there are multiple hangars for different work machines, the position coordinates of the hangar are set by specifying the work machine. In the pre-processing step 44, a provisional field work sequence is calculated from the field position coordinates and the movement route between the fields, and further taking into account the field area, on the condition that the cultivation information indicates that the work type is the same. For fields whose field position coordinates are within a specified range, the field work sequence is calculated so that the fields are continuous on the same work day. The movement route between the fields is calculated so that the movement time is minimized. When calculating the field work sequence, the field area is integrated to calculate so that the number of times materials need to be replenished is reduced. Note that if the field to be worked on is the same or nearly the same as the target field for work that has been done in the past or work that has already been calculated, and if past route data for the same work type is stored in the database 10, the stored route data can be used.

[0031] A first work field is selected in a first work field selection step 45. The first work field may be, for example, a field located at the closest position coordinates to the work implement hangar set in the start point setting step 43, or a field that has the shortest travel time along a travel route from the work implement hangar.

[0032] In step 46 of calculating the travel route between the (N-1)th work field and the Nth work field, when there are multiple routes from the (N-1)th work field to the Nth field, the optimal travel route is calculated. When the currently selected field is the first field (N=1), the route from the work machine hangar (start point) to the first work field is calculated. When the travel route differs depending on the type of work machine, the travel route according to the work machine is calculated. The calculated travel route may also differ depending on the size of the vehicle transporting the work machine. For example, in the case of a multicopter, the travel route can be calculated regardless of steps, so the shortest distance between the fields can be calculated as the travel route, but in the case of a boom sprayer, the travel route is calculated depending on the size of the vehicle, etc., since it is possible to calculate the travel route regardless of steps.

[0033] In the travel time calculation step 47, the travel time on the travel route calculated in the travel route calculation step 46 between the (N-1)th work field and the Nth work field is calculated. The travel time is calculated according to the type of work machine, and the travel time is calculated according to the travel method of the work machine, for example, travel by vehicle or travel by self-propelled. For example, in the case of a boom sprayer, the time for the distance is different between short-distance travel by self-propelled and long-distance travel by vehicle. Also, in the case of a multicopter, the travel route and travel time are different between travel by flying to an adjacent field and travel by vehicle. The travel time can also be calculated by determining whether to apply the speed for long-distance travel or the speed for short-distance travel using the travel distance as a threshold value.

[0034] In S48, it is determined whether or not supplies need to be replenished. Here, the supplies are those necessary for agricultural work, and for example, in the case of a multicopter or a boom sprayer, the supplies include batteries, chemicals, water, and fuel. The amount of supplies to be replenished is calculated based on the type of farm work and the area of ​​the field. When the multicopter is moved by flight, the power consumption required for the movement is also calculated. If material replenishment is necessary (Yes in S48), a material replenishment time calculation step 49 calculates the material replenishment time required depending on the material. If material replenishment is not required (No in S48), the material replenishment time calculation step 49 is not performed.

[0035] In the field work time calculation step 50, the field work time is calculated based on the area and shape of each field to be worked on and the work method. In particular, in fields with many plots in mountainous areas, the area of ​​each field is small, and the shape of the field has a large effect on the work time. The field work time based on the area and shape of the field and the work method may be calculated using categorized data, past performance data, or work times in similar fields.

[0036] In step 51 of calculating the return route and time from the Nth work field, a movement route from the Nth work field to an end point (for example, the storage shed at the start) is tentatively calculated, and the return time is calculated.

[0037] In the work time accumulation step 52, the outside-field work time calculated in the determined outside-field work time calculation step 41, the travel time calculated in the travel time calculation step 47, the material replenishment time calculated in the material replenishment time calculation step 49, the in-field work time calculated in the in-field work time calculation step 50, and the return time calculated in the return route and time calculation step 51 from the Nth work field are accumulated.

[0038] If the work time accumulated in the work time accumulation step 52 is less than the available work time for one day (Yes in S53), or if other target fields remain to be worked on (Yes in S54), the return time from the Nth field is subtracted from the accumulated time (S55), and a new Nth work field (indicating the order of the current target field to be worked on) is selected (S56). In the N+1th work field selection step 56, a new N+1th work target field is selected excluding the Nth work field and the fields up to the (N-1)th work target field that have already been selected as work target fields. For example, in addition to selecting the field located at the closest position coordinates to the Nth work target field, a field that takes the shortest travel time for the work machine along the travel route from the Nth work target field is selected. The first work field selection step 45 and the N+1 work field selection step 56 are work field selection steps. When the (N+1)th work target field is selected in the (N+1)th work field selection step 56, 1 is added to the value of N, and a travel route from the (N-1)th work field to the Nth work field is calculated in the (N-1)th work field to Nth work field travel route calculation step 46.

[0039] When the work time accumulated in the work time accumulation step 52 becomes equal to or exceeds the available work time for one day (No in S53), and there are no other fields to be worked on (No in S54), the fields up to the (N-1)th field to be worked on are calculated as the fields scheduled to be worked on for that day (S57). If work is completed for all of the work target fields in one day (No in S58), the work plan calculation process (S30) ends (S59). If the work cannot be completed for all the fields to be worked on in one day (Yes in S58), the process returns to S41 and performs the one-day work plan calculation process (S41 to S57) for the remaining fields to be worked on as the second day's work plan calculation process. If the work is still not complete for all the fields to be worked on, the process is repeated for the third day, and so on, until the work is completed for all the fields to be worked on, and the number of repetitions M is output as the number of days M required to complete the work.

[0040] In this way, the system calculates the fields to be worked on by accumulating the travel time and the work time in the field, and calculating the fields to be worked on so that the accumulated work time is within the possible work time in one day, which makes it possible to calculate a work plan especially for fields with many plots, such as those in mountainous areas. Furthermore, by adding the time spent working outside the field and the time spent replenishing materials to the calculation, a more accurate and efficient work plan can be calculated.

[0041] 3 to 14 are diagrams showing screen images of the farm work support system according to this embodiment. 3 and 4 show image diagrams of a suitable time list display screen displayed in the suitable time list display step. FIG. 3 shows, as types of agricultural work that have suitable periods, "Fascina head blight prevention" when the cultivated crop is "wheat" and "top dressing" when the cultivated crop is "XX." As shown in Figure 3, for the same work types, "Red mold disease control" and "top dressing," the number of fields and total field area of ​​fields that are the target of work and have the same suitable work period are displayed. That is, for example, for "Red mold disease control," in the suitable work period when the workable start date is 2020 / 04 / 22 and the workable end date is 2020 / 04 / 28, the number of fields that are the target of work is 52 and the total field area is 24 ha, and in the suitable work period when the workable start date is 2020 / 04 / 26 and the workable end date is 2020 / 05 / 02, the number of fields that are the target of work is 60 and the total field area is 32 ha. A "check box" is provided for each target field for which the same work type and the same suitable work period are applicable.

[0042] FIG. 4 shows a state in which a check has been entered in the "check box" for a work target field that is suitable for work when the planned work start date is 2020 / 04 / 22. Entering a check in this box selects the work target field that is suitable for work when the planned work start date is 2020 / 04 / 22, and the selected work target field is displayed in the "Field map display" or becomes a planned subject of the "Work plan". In this way, by displaying a field map or calculating a work plan for farm work selected from the farm work displayed on the suitable time list display screen, a work plan can be created that is suited to the user's situation. The timing list display screen displays the “Display field map,” “Work plan,” and “Finish” buttons, and when at least one check box has been filled in as shown in Figure 4, pressing the “Display field map” button will take you to the field map display screen shown in Figure 5, where you can view the field map. By pressing the "Work Plan" button, the screen will transition to the work plan condition input screen shown in FIG. 6, and by pressing the "Exit" button, the display of the suitable period list can be terminated.

[0043] FIG. 5 shows an image of the farm field map display screen displayed in the farm field map display step. As shown in Fig. 5, fields to be worked on that are suitable for work are displayed in color on a map. The location information of each field recorded in the field information database 11 is associated in advance with the location information of each field displayed on the map, and display on the map can be performed using the location coordinates of the fields to be worked on and the coordinate information held by the map. The map is created based on the field information and cultivation information that are associated and recorded in advance in the database 10. The map includes road information that can be used for route planning. When displaying fields to be worked on that have different optimum work times, the fields to be worked on can be displayed differently for each optimum work time, making it possible to grasp the fields to be worked on for each optimum work time, which makes it easy to grasp the overall picture, especially in cases of fields with multiple plots. In Figure 4, when input is made into multiple check boxes, fields to be worked on with different optimum work times are displayed, and the "different displays" can be distinguished, for example, by color coding or pattern coding. By pressing the "return to suitable timing list" button on the farm field map display screen shown in FIG. 5, the screen will transition to the screen shown in FIG. 3 or FIG. By pressing the “Work Plan” button on the farm field map display screen shown in FIG. 5, the screen transitions to the work plan condition input screen shown in FIG.

[0044] FIG. 6 shows an image of the work plan condition input screen displayed in the condition input step. As shown in Figure 6, for the optimal work period selected as the target of the work plan, the type of agricultural work, the planned start date when work can be started, the planned end date when work can be ended, the number of fields to be worked on, and the total area of ​​fields are displayed. In the work plan condition input screen shown in FIG. 6, conditions for the work plan are input. Either the "work start date" or the "work end date" is entered as a condition. Figure 6 shows the state where the "work start date" has been entered. In this way, by using the work start date or work end date as a condition instead of simply the number of work days, it is possible to create a work plan that uses past weather records and weather forecasts. Also, the type of "work method (work equipment and personnel composition)" and "number of groups" to be used for the work are entered.

[0045] The "work method" is set in the work machine / work method information database 14, and the contents can be confirmed by pressing the "Confirm" button shown in FIG. 6 (FIG. 7). As shown in Figure 7, when "Multicopter A" is selected as the work method, detailed information such as the number of workers, tank capacity, spraying speed, discharge amount, flight time, and work time can be confirmed. In addition, the detailed information shown in Figure 7 can be modified or changed as necessary. In this manner, in the work plan calculation step 30, by calculating the work start date or work end date of the farm work and the farm work method as input conditions, it is possible to create a work plan suited to the user's situation. Pressing the "Back" button on the detailed display screen shown in FIG. 7 causes the screen to transition to that of FIG. By pressing the "Execute" button on the screen shown in FIG. 6, a work plan calculation process is performed (S30), and the screen transitions to a work result display screen shown in FIG.

[0046] FIG. 8 shows an image diagram of the work plan result screen displayed in the work plan result display step. As shown in Figure 8, if the "Work start date" is entered as a condition, the "Work end date" is displayed as the work plan result. Note that if the "Work end date" is entered as a condition, the "Work start date" is displayed as the work plan result. If the "Work end date" falls after the optimal work period (the planned end date when work can be completed), a warning is displayed to the effect that the work will not be completed by the optimal work period, and the user is prompted to re-enter the conditions. At this point, by pressing the "Work plan map display" button, the fields that cannot be worked on at their appropriate time will be identified and displayed. Figure 11(b) shows an image of the map display where fields that cannot be worked on at their appropriate time have been identified. As will be described later, Figure 11(a) is an image of the map display where all fields scheduled for work that are the subject of all work plans are displayed, and fields that cannot be worked on at their appropriate time are displayed in a different color or pattern from the fields scheduled for work. For ease of explanation, the arrows shown in Figure 11(b) point to fields that cannot be worked on at their appropriate time.

[0047] FIG. 9 shows the re-input of conditions on the work plan result screen image diagram. As shown in Figure 9, change the "Work start date" to "2020 / 04 / 23" and click the "Recalculate" button to transition to the work plan result screen shown in Figure 10.

[0048] Figure 10 shows an image of the work plan results screen after recalculation. As shown in Figure 10, the "Work Plan Results" are displayed again. By changing the "Work Start Date" to "2020 / 04 / 23", the "Work End Date" is displayed as "2020 / 04 / 25". In addition, since the "Work End Date" is before the due date for work, the "Grace period until the due date" is displayed. If the actual weather information or weather forecast information indicates that there is a high possibility of rain during the work period, it is preferable to display a message indicating that the grace period should be increased. For example, if the work start date is set to three days after the scheduled work start date, the grace period can be increased by two days by setting the work start date to the scheduled work start date. On the work plan result screen shown in FIG. 10, by instructing the "work plan map display" instruction button, the screen transitions to a work plan map screen shown in FIG.

[0049] 11 to 13 show work plan map screen images displayed in the work plan map display step. FIG. 11(a) shows all fields scheduled for work that are the subject of all work plans, and FIG. 11(b) shows specific fields that cannot be worked at the appropriate time. In FIG. 11(a), the three days from "2020 / 04 / 23" to "2020 / 04 / 25" are displayed differently for each work day. The different displays are achieved, for example, by coloring or pattern division. In this way, all calculated fields scheduled for work are displayed as a total field map, and the fields scheduled for work are displayed differently on a work day basis on the total field map, making it possible to grasp the distribution of fields scheduled for work on a work day basis on the total field map. It is also preferable to show the work sequence on a daily basis, and further to display the routes for moving between fields, work time within a field, material replenishment locations, material replenishment times, etc. When the "Daily display" button is pressed on the work plan map screen shown in FIG. 11, the screen transitions to a work map screen shown in FIG.

[0050] FIG. 12 shows a daily field map. Figure 12 shows the work plan for the work start date, "2020 / 04 / 23," and illustrates the fields to be worked on "2020 / 04 / 23" and the work sequence. The work sequence is displayed above or next to each field on the screen. It is preferable that the daily field map shown in FIG. 12 also display the travel route between fields, work time within the field, material replenishment locations, material replenishment times, and the like. In the daily field map shown in Figure 12, by pressing the "Display entire" button, the entire field map shown in Figure 11 is displayed, and by pressing the "Display next day" button, the daily field map for the next day shown in Figure 13 is displayed.

[0051] FIG. 13 shows the work plan for "2020 / 04 / 24", illustrating the fields to be worked on "2020 / 04 / 24" and the work sequence. In the daily field map shown in Figure 13, by pressing the ``Display previous day'' button, the daily field map shown in Figure 12 can be displayed, and by pressing the ``Display next day'' button, the daily field map for the next day, ``2020 / 04 / 25'', can be displayed.

[0052] In this way, the work plan map display screen displays the fields scheduled for work on a work day basis as a daily field map, and the daily field map displays travel routes, etc., so that the daily field map allows the user to understand the travel routes between the fields scheduled for work. In this way, in the field map display step 27 and the work plan map display step 35, the field to be worked on is displayed differently for each type of agricultural work, so that the field to be worked on can be grasped for each type of work, which makes it easy to grasp the overall picture, especially in fields with multiple plots. In addition, in the work plan map display step 35, by displaying the daily field map together with the total field map, it becomes easy to grasp the overall situation, and it becomes easy to grasp the fields scheduled for work on a work day basis.
