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.
本发明涉及无人驾驶矿用车线控制动系统,空气压缩机与发动机相连,通过发动机动力为制动系统提供压缩空气;干燥器与空气压缩机相连,通过干燥器进行压缩空气的干燥;四回路保护阀与干燥器连接,四回路保护阀的各出气口分别连接至各自的储气筒,以便将压缩空气形成四条独立回路;在无人驾驶状态下,将指令发送给EBS中央控制器,EBS中央控制器识别外部发来指令,控制单通道桥控模块和双通道桥控模块,单通道桥控模块和双通道桥控模块接收到指令后控制电磁调节阀,电磁调节阀进行动作,控制制动气路通断,轮速传感器反馈车速信号给EBS中央控制器,EBS中央控制器通过轮速传感器反馈信号,下发指令控制通过单通道桥控模块和双通道桥控模块气压。
