As a result, the management computer 21 can store the electronic data of the pesticide application certificate. In addition, the management computer 21 may perform procedures related to pesticides by transmitting electronic data of the pesticide spraying certificate to a public institution or the like.

As described above, for example, if the worker performs the spraying work according to the spraying plan and then transmits the spraying information and the position information at the time of spraying on the server 30 side, the spraying work is performed in the field where the spraying work is performed. Certificate management A pesticide spraying certificate can be easily created using a computer 22 or the like.
Various operations of the certificate creation unit 39 are performed by the field identification unit 39A, the calculation unit 39B, and the issuing unit 39C provided in the certificate creation unit 39. The field identification unit 39A, the calculation unit 39B, and the issuing unit 39C are composed of a program and the like stored in the server 30.

The field identification unit 39A performs a process of identifying the field from the position information included in the spraying record (sixth process S6) in creating the certificate. In the calculation process 39B, in the certificate creation, the numerical values required for the certificate are calculated from the spraying results, and at least the processing related to the calculation of the sprayed liquid amount for each field (7th process S7, 9th process S9, 11th process). S11, thirteenth process S13) is performed.
The issuing unit 39C automatically allocates the data of the spraying results to the items shown in the description parts F1, F2, F3, and F4 of the pesticide spraying certificate (first processing S1 to fifth processing S5, The dispersion certificate is issued by performing the 8th process S8, the 10th process S10, the 12th process S12, and the 14th process S14).

Next, the flow of specifying the field from the spraying results and calculating the spray liquid amount will be described in detail.
When calculating the amount of spray liquid, the field identification unit 39A specifies the field (field name) for which the amount of spray liquid is calculated from the position information stored in the actual storage unit 35 (S6: 6th process). In the sixth treatment, the field identification unit 39A estimates the spraying start position and the spraying end position from the spraying amount and position information indicated by the spraying information. For example, as shown in FIG. 9, at the position P1, the spray amount (instantaneous spray amount) is larger than zero, and after the position P1, the instantaneous spray amount is a continuous value, so that the position P1 is sprayed. Estimated to be the starting position. Further, since the spraying amount (instantaneous spraying amount) is continuously zero at the position next to the position P2, the position P2 is estimated to be the position where the spraying ends.

In FIG. 9, the position of the start of spraying and the position of the end of spraying are estimated by using the relationship between the instantaneous spraying amount and the position information. For example, the relationship between the spraying pressure and the position information is estimated. It may be estimated based on the relationship between the total amount of spraying and the position information, or it may be estimated by acquiring signals indicating the start and end of spraying from the spraying device 1, or other methods. It is not limited to going by.

Identify from. Alternatively, the field identification unit 39A specifies from the field registration database the field name corresponding to the field in which the plurality of referenced position information overlaps most among the fields shown in the map data. Further, the field identification unit 39A may specify the field name by obtaining the position of the center of gravity from the position information during spraying and comparing the obtained position of the center of gravity with the position information of the field shown on the map data. It should be noted that the field name is specified by the field specifying unit 39A as an example, and is not limited to the above-mentioned method.

The calculation unit 39B calculates the amount of spraying in the field corresponding to the field name specified by the field identification unit 39A (7th process). In the seventh process, the calculation unit 39B obtains the spraying amount (spraying amount per field) from the vehicle speed, the instantaneous spraying amount, and the spraying pressure from the spraying start position to the spraying end position. The spraying amount is calculated from the relationship between the vehicle speed, the instantaneous spraying amount, and the spraying pressure, but the spraying amount per field may be calculated by integrating the instantaneous spraying amount, or the total spraying amount and spraying at the position where the spraying ends. The amount of spraying per field may be determined by the difference from the total amount of spraying at the starting position, or may be determined by other methods, and is not limited.

The issuing unit 39C associates the field name specified by the field specifying unit 39A with the spraying amount calculated by the calculation unit 39B to obtain a spraying certificate (8th process). For example, as shown in FIG. 8A, in the eighth treatment S8, when the field name specified by the field specifying unit 39A is "field A" and the spray amount of the field A is "1000L", the issuing unit 39C The issuing unit 39C associates the "1000L" calculated by the calculation unit 39B with the "spraying liquid amount" column in which the "field name" in the pesticide spraying work history is "field A".
