Embodiment Construction

[0015] see figure 1 and figure 2 , The through-beam laser tractor auxiliary navigation control system involved in the present invention mainly includes a laser sensor transmitting terminal 1, a laser sensor receiving terminal 2, a navigation indicating terminal 4 and a control core 3.

[0016] In order to describe the implementation process of the present invention more clearly, take Dongfanghong-LX754 tractor as an example here. The laser sensor transmitter 1 is installed on the steering kingpin of the front wheel of the tractor. It consists of a through-beam laser transmitter, a laser transmitter bracket, an independent power supply, a stepper motor, a stepper motor driver and a mounting bracket. The laser transmitter is powered by 12V The independent power supply is powered, and the independent power supply and the laser emitter are fixed on the rotating shaft of the stepping motor through the laser emitter bracket, and the stepping motor is connected with the steering ki...

Abstract

The invention relates to an opposite-type laser tractor aided navigation control system which comprises a laser sensor emitting end, a laser sensor receiving end, a navigation indicating terminal and a control core. A laser emitter used by the laser sensor emitting end and a laser receiver used by the laser receiving end are arranged on the same horizontal plane. The laser receiver points to the laser emitter. The emitting end deflects synchronously along with front wheels of a tractor, and meanwhile the laser emitter rotates at a constant speed with a stepping motor. The navigation indicating terminal is used for indicating tractor off-course information. STM32 is used as a main control chip of the control core, the tractor off-course information is judged by obtaining the time interval between two-time level signal changing of the laser receiver, and the navigation indicating terminal is controlled to display an off-course angle in a pointer-deflection mode. Based on a laser sensor and a single chip microcomputer control technology, straight line navigation auxiliary control during a tractor running process is achieved, compared with navigation control systems such as a GPS, cost is lower, and tractor working accuracy and efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the field of control systems, in particular to a through-beam laser tractor auxiliary navigation control system. Background technique [0002] Nowadays, exploring and establishing a precision agricultural operation mode that is in line with my country's national conditions has become the only way for my country's agricultural sustainable development. Precision agricultural mechanization technology involves various links such as arable land, sowing, fertilization, irrigation and harvesting, and whether the agricultural machinery can run in a straight line during operation has a direct impact on the implementation of the above links. Straight-line driving of the tractor can reduce land re-cultivation and missing tillage, ensure that the rows of crops are kept parallel when sowing, and provide prerequisites for mechanical topdressing and weeding in the mid-term of crops. During tractor field operations, the driving path of the op...
