The invention discloses a parking brake control protection system. The parking brake control protection system involves pressure regulating valves, electromagnetic valves, pressure switches and a contactor; the inlet ends of the pressure regulating valves are connected with main air pipes, and the inlet ends of the electromagnetic valves are connected with the outlet ends of the pressure regulating valves; the inlet end of the pressure switches are connected with the outlet ends of the electromagnetic valves, and the outlet ends of the pressure switches are connected with a unit brake parkingcylinder; and the contactor is electrically connected with the pressure switches and is electrically connected with an engine or a gearbox controller. By arranging the contactor, the contactor is electrically connected with the pressure switches and electrically connected with the engine or the gearbox controller, and therefore an engineering vehicle can be automatically controlled to return to the idle speed when the engineering vehicle parks and brakes accidentally during operation; by arranging an indicator lamp, a driver is reminded during parking brake work; and by arranging the second pressure regulating valve, the second electromagnetic valve, a second cock and a reversing valve, redundancy of parking brake control is achieved.

    本发明公开了一种停车制动控制保护系统,包括:调压阀、电磁阀、压力开关和接触器;调压阀的入口端与总风连接;电磁阀的入口端与调压阀的出口端连接;压力开关的入口端与电磁阀的出口端连接,压力开关的出口端与单元制动器停放缸连接;接触器与压力开关电连接,且和发动机或者变速箱控制器电连接。通过设置接触器,电连接压力开关,且电连接发动机或者变速箱控制器,实现当工程车运行中停车制动意外工作时,能够自动控制工程车回怠速;通过设置指示灯,实现在停车制动工作时提醒司机;通过设置第二调压阀、第二电磁阀、第二塞门和换向阀,实现停车制动控制的冗余。
