A control method for path planning of an automatic navigation system

Abstract

The invention relates to a path planning control method for an automatic navigation system. Signal communication between a control terminal, an electronically controlled steering wheel and a GPS satellite signal receiver is established, and then based on the positioning information of the GPS satellite signal receiver, users can select After setting the information of point A, point B and line distance of the planned route on the control terminal, the control terminal automatically generates the operation path. Finally, the control terminal calculates the agricultural machinery and operation in real time based on the set operation path and the positioning data of the GPS satellite signal receiver. The position deviation of the path, the calculated deviation data is used as the control signal of the electronically controlled steering wheel, and the electronically controlled steering wheel can accurately track the working path of the agricultural machinery according to the control signal. The invention simplifies the control program for automatic navigation path planning and the planning program for optimizing the path path, and at the same time, it can realize the automatic line wrapping operation of agricultural machinery, accurately track the set operation path for operation, and make the agricultural machinery operation more automatic.

Description

technical field [0001] The invention relates to the technical field of automatic navigation control of agricultural machinery, in particular to a path planning control method for an automatic navigation system. Background technique [0002] my country's agricultural automatic navigation technology has developed rapidly with the support of precision agricultural technology, and is widely used in various processes of agricultural production. The path planning function of the automatic navigation system can make the tractor work area cover the entire farmland, reduce overlapping paths, and improve work efficiency. and job quality. As one of the core control technologies in the agricultural machinery automatic navigation system, the agricultural machinery operation path planning control technology designs a navigation route with high operation efficiency based on the actual situation of the farmland plot, and the agricultural machinery completes the agricultural production work b...
