Excavator engine start-stop control system and method
The invention provides an excavator engine start-stop control system and method.The excavator engine start-stop control system comprises a switch assembly, a power source control unit, a power source relay, a main controller, a start control unit and an engine controller; one end of the one-key starting switch is respectively connected with the power supply control unit, the main controller and the normally open contact output end of the power supply relay, and the other end of the one-key starting switch is respectively connected with the positive electrode of the excavator system power supply and the input end of the normally open contact of the power supply relay; the coil end of the power supply relay is connected with the main controller through a diode, and the main controller is respectively connected with the starting control unit and the engine controller. According to the invention, control of power-on and power-off of the whole machine and start-stop of the engine is realized through multi-stage safety redundancy control, the function safety design requirement of the system under coupling start-stop control can be effectively ensured, and the system reliability is enhanced while the intelligent degree of the system is improved.
本申请提供了一种挖掘机发动机启停控制系统及方法，包括开关组件、电源控制单元、电源继电器、主控制器、启动控制单元和发动机控制器，所述开关组件包括一键启动开关，所述一键启动开关的一端分别连接电源控制单元、主控制器和电源继电器常开触点输出端，所述一键启动开关的另一端分别连接挖掘机系统电源正极和电源继电器常开触点输入端，所述电源继电器的线圈端与所述主控制器通过二极管连接，所述主控制器分别与启动控制单元和发动机控制器连接。本申请通过多级安全冗余控制实现整机上断电与发动机启停的控制，能有效保证耦合启停控制下的系统功能安全设计要求，提升了系统智能化程度的同时增强了系统的可靠性。
