Description

The present invention relates to an agricultural work support system that is a system for supporting agricultural work using agricultural machines.

Traditionally, agricultural work has often been carried out based on know-how, empirical rules, etc., and those who are new to it need support. As support, for example, a method of acquiring know-how and empirical rules through inheritance from existing business operators can be considered. However, the reality is that there are many cases that require a great deal of time and cost, and 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 disclosed in Patent Document 1 that includes a spraying drone and a drone management terminal is known. In the system of Patent Document 1, a normalized difference vegetation index (NDVI) in a field is inputted to a drone management terminal, and an optimal value of the spray amount of a spray agent is estimated according to a learning model. The spraying drone is configured to spray the applicable amount of spraying agent onto the target field.

Furthermore, even if it were possible to obtain information using agricultural machines, there is no function to collect information using the above system. For this reason, it is extremely difficult to obtain and collect a wide range of information from many implementation patterns. Therefore, in the system of Patent Document 1, even when a learning model is utilized, it is difficult to actually derive an optimal value, and it cannot be said that support for agricultural work is appropriate. In view of the above, there is a need for a system that allows users to receive optimal support when carrying out agricultural work without the need to acquire know-how or empirical rules.

As shown in FIG. 5, when the first agricultural working machine 10 performs agricultural work in the first field F1, the first agricultural working machine 10 acquires field information. In this embodiment, as the field information, the contour of the first field F1 and the state of the area to which the first field F1 belongs are respectively acquired. Here, the local conditions include, for example, the temperature Tm1, the humidity Hm1, and the like. The temperature Tm1, the humidity Hm1, etc. are detected by the detection device 11e included in the traveling vehicle 11 when the first agricultural machine 10 travels in the first field F1.

The outline of the first field F1 may be acquired as follows, for example. The first agricultural working machine 10 enters the first field F1, and the first agricultural working machine 10 goes around along the edge of the first agricultural field F1 before performing agricultural work. At this time, the positioning device 11d of the traveling vehicle 11 detects the vehicle body position. Specifically, an inflection point K1 (latitude, longitude, etc.) is detected in the travel trajectory K of the first agricultural machine 10 in the first field F1. The inflection point K1 is a point at which a change occurs in the traveling direction of the traveling vehicle 11. For example, when the first field F1 is substantially square, the inflection point K1 is a position corresponding to the four corners of the first field F1. 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 determined by the communication device 11g (first information transmitting unit 11h1) of the traveling vehicle 11. ) is transmitted to the server 30.

In this embodiment, the driving mode corresponding to agricultural work in the first field F1 is acquired as the driving information. Here, examples of the driving mode include a driving 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, or may be detected by the positioning device 11d provided in the traveling vehicle 11, when the first agricultural machine 10 travels in the first field F1. may be detected.

The travel route L1 in the first field F1 may be acquired as follows, for example. After the contour O1 of the first field F1 is determined as described above, the first agricultural machine 10 moves to one of the positions corresponding to the inflection point K1 (the four corners of the first field F1) in the first field F1. From then on, they started driving and farming. The first agricultural machine 10 starts from the inflection point K1 and moves straight approximately parallel to the ridgeline of the first field F1. Thereby, a straight route length L1a is formed. In the first field F1, when the first agricultural working machine 10 reaches the turning position T1 near the end, the first agricultural working machine 10 turns 180 degrees and moves straight in the opposite direction to L1a. Thereby, the straight route length L1b is formed. This running mode is repeated, and the running route L1 becomes a meandering route as a whole. At this time, the positioning device 11d of the traveling vehicle 11 detects a plurality of turning positions T1 (latitude, longitude, etc.). The straight lines obtained by connecting the detected turning positions T1 are 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 lengths L1a, L1b, and route width W1) of the first farm field F1 determined as described above and the vehicle speed V1 of the first agricultural machine 10 are based on the speed of the traveling vehicle 11. The information is transmitted to the server 30 by the communication device 11g (first information transmitter 11h1).

Here, the operation mode includes, for example, an interval D1a for planting seedlings S1 on the ground of the first field F1 using the agricultural equipment 12, and a depth D1b for planting the seedlings S1 toward the ground of the first field F1 using the agricultural equipment 12. etc. can be mentioned. Either or both of the distance 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 agricultural 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). Here, the rotation speed of the planting mechanism 12b may be determined based on an operation signal of the operating tool 11f (rotation speed changeover switch of the planting mechanism 12b), or may be detected by a rotation speed sensor of the planting mechanism 12b. good.

The depth D1b may be determined based on the position of the coupling machine 11c in the vertical direction and the radius vector of the planting mechanism 12b when the first agricultural machine 10 travels in the first field F1.
