田间作业机组激光导引系统设计与试验
Design and Test of Laser Guidance System for Field Work Units
摘要
Abstract
In order to improve the straightness of the field work,the laser guidance system was designed based on its good directivity, small divergence angle, high resolution, no electromagnetic interference and no accumulative error. This system is mainly composed of a laser emitting device, leveling device, laser receiving device etc. Laser emitter emitted the red light laser, which was received by the laser receiver installed on the tractor and converted into electric signal by demodulation,the LED indicated the direction deviation and assisted the driver in adjusting the direction and moving straightly. The system structure, working principle and the key parts design have been elaborated. The primary test showed the guidance accuracy of the laser guidance system was less affected by the external light, the distance deviation was about 3.18 cm in the range of 200m.Compared with the row maker, the system improved the operation accuracy.关键词
