Auxiliary linear tracking control system for operation of distributed agricultural machine

Abstract

The invention relates to an auxiliary linear tracking control system for operation of a distributed agricultural machine, which comprises a GPS receiver for receiving information on the current operation position coordinate of the agricultural machine, a control terminal for calculating the yawing distance between the agricultural machine and the current operation navigation line according to the position coordinate and transmitting the yawing distance information to a navigation indicating controller, and the navigation indicating controller comprises a two-color light-emitting diode and a plurality of single-color light-emitting diodes and controlling the different light-emitting states of the two-color light-emitting diode and the single-color light-emitting diodes according to the yawing distance. The auxiliary linear tracking control system achieves the linear tracking auxiliary control of a tractor in the operation process based on the digital design of an operation navigation target route of the tractor, the GPS navigation and an embedded control technique, is more precise than conventional tractor operation navigation techniques with a scriber, foam spraying and the like, is not limited by the farmland operating environment, and improves the operation quality and the efficiency.

Description

technical field [0001] The invention relates to a control system, in particular to a distributed agricultural machine operation auxiliary linear tracking control system. Background technique [0002] During tractor field operations, the operation unit has poor maneuverability, and it is easy to re-plow, miss plow, and travel more distances, which affects production efficiency. In order to reduce the rework and missed work between the working ridges, the traditional method of marking the field with a marker or spraying foam is used as the basis for the driver's work navigation. With the development of domestic precision agricultural technology research in recent years, researchers have developed an agricultural machinery navigation system, which includes GPS, PC104 computers and navigation light sticks, which can provide navigation instructions for agricultural machinery field operations. [0003] For the above two navigation and indication methods for agricultural machinery...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a distributed tractor operation auxiliary linear tracking control system to solve the problems of weak adaptability and poor navigation effect of traditional markers and foam spraying navigation methods, and improve the linear tracking control effect of tractor field operations. Reduce the overlap and omission rate between rows in the operation process, and improve the quality and efficiency of field operations

At the same time, from the system design and implementation method, the problems of complicated wiring, poor reliability and poor versatility of the existing agricultural machinery navigation and indication system are eliminated
