Heavy -duty car air pressure brake assists gas supply system

Heavy -duty car air pressure brake assists gas supply system is become by gas pressure sensor, singlechip, motor and supplementary air compressor unit, and in the gas holder, the signal of gas pressure sensor end links to each other with the singlechip in the car in the sense terminal setting of gas pressure sensor, and the singlechip links to each other with the motor, and the motor links to eachother with supplementary air compressor machine, and air compressor machine parallel connection in supplementary air compressor machine and the car is to the car in the gas holder. The utility modeldiscloses utilize singlechip receiving pressure sensor signal and judge the pressure state in the air braking system gas receiver, during hypotony when the gas receiver in, in time to providing additional atmospheric pressure in the gas receiver, make the automobile keep better brake performance, prevent the incident emergence. 重型汽车气压制动辅助供气系统，由气体压力传感器、单片机、电动机和辅助空压机组成，气体压力传感器的检测端设置在车内储气罐中，气体压力传感器的信号端与单片机相连，单片机与电动机相连，电动机与辅助空
