Description

The present invention relates to an agricultural work support system, which is a system for supporting agricultural work with an agricultural work machine.

Conventionally, agricultural work is often carried out based on know-how, rules of thumb, etc., and support is required for those who newly carry out the work. As support, for example, a method of acquiring know-how and rules of thumb by inheriting from a past business operator can be considered. However, there are many cases where a large amount of time and cost are required, and the fact is that succession does not proceed smoothly. In view of these circumstances, systems using information and communication technology have been developed in recent years.

As a system for supporting agricultural work, for example, a system of Patent Document 1 including a drone for spraying and a drone management terminal is known. In the system of Patent Document 1, the normalized difference vegetation index (NDVI) in the field is input by the drone management terminal, and the optimum value of the spraying amount of the spraying agent is estimated according to the learning model. The spraying drone is designed to spray the spraying agent in the spraying amount to the target field.

Japanese Unexamined Patent Publication No. 2021-142771 (Claim 1, paragraph 0034, etc.)

In the system in Patent Document 1, the learning model is based on vegetation big data, and represents the relationship and regularity between various data related to vegetation. As the vegetation big data, the data stored in advance in the server is used. That is, apart from the above system, for example, it is necessary to generate vegetation big data before constructing the system.

In general, this kind of big data can be generated by acquiring and collecting information for each of a large number of agricultural implementation patterns. However, many agricultural work machines are not supposed to acquire information for big data generation. Moreover, even if the information can be acquired by the agricultural work machine, the function of collecting the information by the above system is not found. Therefore, it is extremely difficult to acquire and collect a wide range of information from many implementation patterns. Therefore, in the system of Patent Document 1, it is difficult to actually derive the optimum value even when the learning model is used, and it cannot be said that the support for agricultural work is appropriate. From the above, there is a demand for a system that can receive optimal support when carrying out agricultural work without having to know know-how and rules of thumb.

Therefore, in view of the above request, an object of the present invention is to provide a system capable of receiving optimum support when carrying out farm work in a farm work support system which is a system for supporting farm work with a farm work machine. do.

As shown in FIG. 5, when the first farm work machine 10 carries out farm work in the first field F1, the first farm work machine 10 acquires the field information.

The temperature Tm1, the humidity Hm1, and the like are detected by the detection device 11e included in the traveling vehicle 11 when the first agricultural work machine 10 travels in the first field F1.

Specifically, the inflection point K1 (latitude, longitude, etc.) is detected in the traveling locus K of the first agricultural work machine 10 in the first field F1. The inflection point K1 is a point where the traveling vehicle 11 changes in the traveling direction. For example, when the first field F1 is a substantially quadrangle, the inflection point K1 is a position corresponding to the four corners thereof. The shape obtained by connecting the detected inflection points K1 is determined as the contour O1 of the first field F1.

The contour O1 of the first field F1 determined as described above and the state of the area to which the first field F1 belongs (temperature Tm1, humidity Hm1, etc.) are the communication device 11g (first information transmission unit 11h1) of the traveling vehicle 11. ) Is to be transmitted to the server 30.

In the present embodiment, as the traveling information, the traveling mode corresponding to the farm work in the first field F1 is acquired. Here, examples of the traveling mode include a traveling route L1, a vehicle speed V1, and the like. The vehicle speed V1 may be detected based on the rotation speed sensor of the prime mover 11a included in the traveling vehicle 11 when the first agricultural work machine 10 travels in the first field F1, or may be detected by the positioning device 11d provided in the traveling vehicle 11. It may be detected.

The traveling route L1 in the first field F1 may be acquired, for example, as follows. After the contour O1 of the first field F1 is determined as described above, in the first field F1, the first agricultural work machine 10 is one of the positions (four corners of the first field F1) corresponding to the inflection point K1. From, we will start running and farming work. The first agricultural work machine 10 starts from the inflection point K1 and goes straight in substantially parallel to the ridgeline of the first field F1. As a result, the straight route length L1a is formed. In the first field F1, when the first agricultural work machine 10 reaches the turning position T1 near the end, the first agricultural work machine 10 turns 180 degrees and goes straight in the direction opposite to L1a. As a result, the straight route length L1b is formed. This traveling mode is repeated, and the traveling route L1 becomes a meandering route as a whole. At this time, a plurality of turning positions T1 (latitude, longitude, etc.) are detected by the positioning device 11d of the traveling vehicle 11. The straight line obtained by connecting the detected turning positions T1 is determined as the straight route lengths L1a and L1b, and the route width W1 between the straight route lengths L1a and L1b is determined.

The traveling route L1 (turning position T1, straight route length L1a, L1b, and route width W1) of the first field F1 determined as described above, and the vehicle speed V1 of the first agricultural work machine 10 are the traveling vehicle 11. It is transmitted to the server 30 by the communication device 11g (first information transmission unit 11h1).

In the present embodiment, as the operation information, the operation mode of the farm work device 12 corresponding to the farm work in the first field F1 is acquired. Here, as an operation mode, for example, the interval D1a for planting the seedling S1 on the ground of the first field F1 with the agricultural work device 12, and the depth D1b for planting the seedling S1 toward the ground of the first field F1 with the agricultural work device 12. And so on. Either one or both of the interval D1a and the depth D1b may be acquired.

The interval D1a may be determined based on the vehicle speed of the traveling vehicle 11 and the rotation speed of the planting mechanism 12b when the first farm work machine 10 travels in the first field F1. More specifically, when the vehicle speed of the traveling vehicle 11 is V1 (m / s) and the rotation speed of the planting mechanism 12b is Vr (1 / s), V1 / Vr = D1a (m) may be set. Here, the rotation speed of the planting mechanism 12b may be determined based on the operation signal of the operating tool 11f (rotation speed changeover switch of the planting mechanism 12b), or may be detected by the rotation speed sensor of the planting mechanism 12b. good.

The depth D1b may be determined based on the vertical position of the coupling machine 11c and the radius of the planting mechanism 12b when the first farm work machine 10 travels in the first field F1. More specifically, the height of the coupler 11c from the ground is H1a (m), the separation distance between the support shafts of the coupler 11c and the planting mechanism 12b is H1b (m), and the radius of the planting mechanism 12b is H1c (m). ) May be set as H1c- (H1a-H1b) = D1b (m).
