Embodiment Construction
[0015] Specific embodiments of the present invention will be discussed in detail below in conjunction with the accompanying drawings.
[0016] The principle of the present invention is to adopt PLC as the core of the control system. Tilt sensor, liquid temperature sensor, liquid level sensor, etc. are used as PLC analog alarm input; emergency stop button and pressure relay are used as PLC switch alarm input; buttons and selection switches on the main control box (local) and remote control button box (remote) As the PLC switching value action input; through the logic program in the PLC, the switching value output controls the action of the motor and solenoid valve to realize the lifting and lowering of the frame, the vertical and horizontal travel, the opening and closing of the upper working frame, and the clamping of the clamping device on the working frame Or relax; the switching value outputs sound and light alarms for various faults.

The invention provides an electric control system for a multifunctional hydraulic working platform for large ships. A PLC module of a PLC main control box of the electric control system consists of amain operating unit, an analog input and output module, a switching quantity input module, and a switching quantity output module. Safety monitoring signals are connected to the analog input and output module and the switching quantity input module and control button signals of the main control box and button signals of a remote control button box are connected to the switching quantity output module. The switching quantity output of the PLC controls a motor, an electromagnetic valve and a sound-light alarm device separately via an intermediate relay. The electric control system has the advantages of simple operation, safety, reliability and convenient maintenance.
