Problems solved by technology

The invention improves the existing manned braking system, and solves the problem that the traditional mining vehicle uses a relay valve to realize the control of the braking system. The foot valve is controlled by the brake pedal, and the foot valve and the relay valve of the chassis pass through The gas pipeline is connected, and the brake function is realized by directly controlling the opening and closing of the relay valve through the foot valve. All the circuits in it are controlled by the gas circuit, and it is impossible to realize the problem of unmanned modification.

Abstract

The invention relates to a drive-by-wire brake system for an unmanned mine. An air compressor is connected with an engine, and compressed air is provided for the brake system through power of the engine; a dryer is connected with the air compressor, and compressed air is dried through the dryer; a four-loop protection valve is connected with the dryer, and each air outlet of the four-loop protection valve is connected with the corresponding air storage cylinder, so that compressed air forms four independent loops; in an unmanned driving state, an instruction is sent to an EBS central controller, the EBS central controller recognizes the instruction sent from the outside and controls a single-channel bridge control module and a double-channel bridge control module, the single-channel bridge control module and the double-channel bridge control module control an electromagnetic regulating valve after receiving the instruction, the electromagnetic regulating valve acts, a brake gas circuit is controlled to be connected or disconnected, a wheel speed sensor feeds back a vehicle speed signal to the EBS central controller, and the EBS central controller feeds back the signal through the wheel speed sensor and issues an instruction to control the air pressure passing through the single-channel bridge control module and the double-channel bridge control module.

Description

technical field [0001] The invention relates to the technical field of automatic control, and more specifically, the invention relates to a brake-by-wire braking system for an unmanned mining vehicle. Background technique [0002] Mining trucks are off-highway vehicles, mainly used in mines and engineering. They are more durable than ordinary trucks and carry more load. From a structural point of view, there seems to be no big difference between mining trucks and ordinary dump trucks, and the volume of knowledge is larger. But in fact, mining trucks are essentially different from ordinary dump trucks in terms of design concept. Ordinary dump trucks are used for road transportation, and mine trucks are used for mine construction operations. Therefore, the entire vehicle and parts of mine trucks are designed and manufactured for such users in consideration of the mine operating environment. . [0003] Traditional mining vehicles use relay valves to control the braking sys...
