Abstract

The invention belongs to the field of intelligent agricultural equipment and provides a self-propelled caterpillar band chassis vehicle remote control system which is used for remotely controlling a self-propelled caterpillar band chassis vehicle. The system comprises an execution unit, a pneumatic unit and a control unit. The execution unit comprises a left turning air cylinder (14), a right turning air cylinder (13), a clutch air cylinder (6), a high and low gear shifting air cylinder (19), a transverse multi-gear shifting air cylinder (22) and a longitudinal multi-gear shifting air cylinder (24). The pneumatic unit comprises an air pump (26), a one-way valve (27), an air storage tank (28), a pneumatic three-piece unit (29), a pressure controller (30), an overflow valve (31), a hand slide valve (32), a compensated flow control valve (33), an electromagnetic valve (34) and a position sensor (35). The control unit comprises a signal receiving device, a signal transmitting device and a programmable logic controller. The remote control system is quite suitable for working under the conditions of the limited working space, the complex road condition and the severe environment, man-machine separation is achieved, and working safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of intelligent agricultural equipment, and in particular relates to a remote control system and a control method for a self-propelled crawler chassis vehicle. Background technique [0002] Agricultural mechanization, automation, and intelligence are the central links of my country's agricultural modernization, the basic means to increase production, and the necessary conditions and fundamental ways to increase labor productivity, reduce labor intensity, and ensure operational safety. The self-propelled crawler chassis has the characteristics of large load, strong off-road performance, and small turning radius. It plays an important role in the development of agricultural mechanization and plays an important role in high-intensity operations such as pesticide application, harvesting, and transportation. role. However, in some specific terrain environments, especially in mountainous or hilly areas, the terrain is undul...
