A Distributed Agricultural Machinery Operation Auxiliary Linear Tracking Control System

Abstract

The invention relates to a distributed agricultural machinery operation auxiliary linear tracking control system, the system includes: a GPS receiver for receiving coordinate information of the current operation position of the agricultural machinery; a control terminal for calculating the distance between the agricultural machinery and the current operation navigation line according to the position coordinates The yaw distance between them, and the information of the yaw distance is sent to the navigation indication controller; the navigation indication controller includes a two-color light-emitting diode and several single-color light-emitting diodes, according to the size of the yaw distance, control all The two-color light-emitting diode and the single-color light-emitting diode are in different light-emitting states. Based on the digital design of the tractor operation navigation target route, GPS navigation and embedded control technology, the present invention realizes the straight-line tracking auxiliary control of the tractor operation process, which is more accurate than traditional tractor operation navigation technologies such as markers and foam spraying, and is not affected by the farmland operation environment. Limits, work quality and efficiency are improved.

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...
