The invention discloses a control device and an operation method of a power unit of a road-rail dual-purpose vehicle. The control device comprises a hydraulic system and an electrical system, and further comprises an electrical control panel and a remote controller, wherein a control button on the electrical control panel can simultaneously control a plurality of oil cylinders to work, so that debugging is convenient; and a remote control button on the remote controller can only control the related oil cylinders to work simultaneously, so that safety is guaranteed. A reversing valve a is arranged on the hydraulic system, and the electrical control panel is electrically connected with the reversing valve a, so that the electrical system can be controlled by the remote controller to indirectly or directly control the oil cylinders, and therefore, lifting synchronism of the oil cylinders can be guaranteed, a vehicle side-tipping phenomenon caused by asynchronous lifting of the oil cylinders is prevented; and an alarm can be given when pressure is abnormal in a lifting process of the oil cylinders, and therefore, safety of an operator and the vehicle is protected.

    本发明公开了一种公铁两用车的动力单元的控制装置及操作方法,包括液压系统和电气系统,还包括电气控制面板和遥控器;电气控制面板上的控制按钮可以同时控制多个油缸工作,方便调试;遥控器上的遥控按钮只能控制相关的油缸同时工作,保证安全。液压系统上有换向阀a,电气控制面板与换向阀a之间存在电连接,可通过遥控器控制电气系统间接或电气控制面板直接对油缸控制,保证通过本方案能实现油缸升降的同步性,防止油缸升降不同步而使车辆侧倾现象,并且能在油缸升降过程中出现压力异常时进行报警,保护操作人员和车辆的安全。
