Abstract

The invention relates to a remote-control driving assist system for high-clearance plant protection machinery and an application method thereof, and belongs to the technical field of plant protectionmachinery. The remote-control driving assist system for high-clearance plant protection machinery comprises a chassis, a steering closed-loop control system and a speed closed-loop control system; thesteering closed-loop control system and the speed closed-loop control system are installed on the chassis; the steering closed-loop control system controls steering angle of the chassis; the speed closed-loop control system controls traveling speed of the chassis; an industrial camera mounted in the front of the chassis acquires information of front environment in real time; the traveling predicted path of the chassis is calculated through a steering angle math model, the predicted path is loaded to an environment video acquired by the industrial camera in real time to form assist video information; network bridge B is arranged on the chassis and is wirelessly connected with external network bridge A; the network bridge A is connected with a PC (personal computer) main board to allow remote assist video information and feedback command high-speed propagation. The remote-control driving assist system for high-clearance plant protection machinery and the application method thereof havethe advantages that environment information can be acquired in real time, the traveling path is preloaded, remote operation is precise, operation safety is high, and plant protection efficiency and effect are good.

Description

technical field [0001] The invention belongs to the field of plant protection machines, and more specifically relates to a remote control auxiliary driving system for high ground clearance plant protection machines and a method for using the same. Background technique [0002] The high-gap chassis is mainly used for field plant protection. The driver controls the high-gap plant protection machine to spray pesticides in the field. Due to the drift of pesticide droplets, the driver's body is vulnerable to damage from pesticide chemicals, and even poisoning accidents occur. In addition, the driver is exposed to the harsh environment of the field for a long time, and is prone to premature fatigue, which seriously affects the physical and mental health of the driver. Remote control technology can realize long-distance machine operation control, and has been widely used in military, industrial, medical and other fields. Combining remote control technology with agricultural produc...
