The invention provides a towed engineering machinery start-stop control system and method, the control system provided by the invention comprises a start switch, a power supply relay, a controller and an electric control cabinet, the start switch is connected with a constant power supply through a first safety piece, and the start switch comprises a first port C1 and a second port C2; the first port C1 is electrically connected with the positive pole of a coil of the power supply relay, one end of a contact terminal of the power supply relay is connected with a constant power supply, and the other end outputs key power; the second port C2 is electrically connected with the controller, the controller is electrically connected with the electric control cabinet and connected with a key through a second safety piece, and the electric control cabinet is electrically connected with the main motor. The basic starting function is achieved through the first port and the second port of the starting switch, the flexibility that the main motor can be independently controlled at the cab end and the electric control cabinet end is achieved, and meanwhile the requirement for continuous power supply of a whole vehicle power source after the main motor is turned off is met.

    本公开提供了一种拖电式工程机械启停控制系统及方法,本公开提供的控制系统包括:启动开关、电源继电器、控制器和电控柜,所述启动开关通过第一保险片与常电电源连接,包括第一端口C1和第二端口C2;所述第一端口C1与所述电源继电器的线圈正极电连接,所述电源继电器的触点端子一端接常电电源,另一端输出钥匙电;所述第二端口C2与所述控制器电连接,所述控制器与所述电控柜电连接,并通过第二保险片连接钥匙电,所述电控柜与主电机电连接。通过启动开关的第一和第二端口实现基础的启动功能,实现了主电机在驾驶室端和电控柜端均可独立控制的灵活性,同时,满足了主电机关闭后整车电源持续供电的需求。
