Working device, working control method and system thereof and unmanned vehicle

Abstract

The invention provides a working control method of a working device. The working control method includes following steps: acquiring profile feature information of a worked object; acquiring azimuth information of the working device working on the operated object relative to the worked object; acquiring swing angle W of the working device for the worked object according to the profile feature information of the worked object and the azimuth information; controlling the working device to work on the worked object according to the swing angle W. By the method, when the working device works for spraying, accurate coverage of a sprayed material to branches and leaves of the worked object is realized, and the problem that vehicle-mounted spraying is prone to causing waste in the prior art is solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular, the invention relates to an operation control method and system of an operation device, an operation device and an unmanned vehicle. Background technique [0002] The use of operating devices for crop planting operations is becoming more and more popular among fruit farmers. Due to the high intensity of farmland and forestry operations and the greater impact of the natural environment, traditional artificial pesticide spraying is gradually being replaced by vehicle-mounted spraying and unmanned vehicle spraying. The way or drone spraying and other ways to replace. Among them, when using the vehicle-mounted spraying method, it is necessary to continuously spray pesticides outward while the vehicle is moving forward, which easily causes a waste of pesticides. Therefore, at present, more methods of spraying pesticides by unmanned vehicles or drones are used. However, the exist...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing vehicle-mounted spraying method causes pesticide waste and environmental pollution due to spraying in all directions;

[0004] 2. When using drones to work, since it is sprayed from top to bottom, it is difficult to penetrate thick leaves, and when spraying from top to bottom, it is difficult to spray pesticides on the back of leaves with relatively serious insect damage. lead to poor spraying effect;

[0005] 3. For large crops with large height and crown width, such as large fruit trees, it is impossible to completely cover the whole crop with pesticides when spraying, and the spraying is not comprehensive;

[0006] 1. For tall plants and crops with narrow crowns, the switching of spraying directions is not flexible enough, and the efficiency of spraying is low

[0007] In summary, in the existing technology, spraying is wasteful, the spraying effect is not good, the spraying accuracy is not high, the scope of application is not wide, and the efficiency is low
