The invention discloses a power-saving control system of a double housing planer, which comprises a cabinet body, a main loop unit, a frequency converter VVVF control unit, a programmable controller (PLC) input and output unit, a cutter lifting and indicating lamp unit and a relay protection unit, wherein all the units are arranged in the cabinet body; a main circuit is connected with a lubricating motor RB, a vertical turret motor C, a right turret motor Y, a left turret motor Z, a cross beam lifting motor H and a cross beam clamping motor J through circuit breakers 1QF-7QF and contactors 1KM respectively; the frequency converter VVVF output is connected to a main motor M; and the PLC input and output unit consists of an input part and an output part. The power-saving control system of the double housing planer has the advantages of simple structure, strong reliability, convenient speed adjustment, energy conservation, running speed improvement and cutting efficiency improvement, andcan be widely applied to cutting mechanical equipment.

The invention relates to a ship propulsion and power equipment large-scale vibration isolation system centering monitoring device. 7 vertical displacement sensors, 3 horizontal displacement sensors, 2 longitudinal displacement sensors and rotation speed and temperature sensors are arranged between a propulsion and power equipment large-scale vibration isolation device raft frame and a hull; a programmable controller, an A / D module, a communication module and a power supply module and the like are integrated in a controller unit; and the communication module has a PC communication interface. A touch display screen, indicating lamps and a switch and the like are integrated on a panel. All of the sensors are connected with the A / D module; the A / D module converts analog signals output by the sensors into digital signals; and the programmable controller calculates the centering state of a propulsion engine under a running status and pose of the raft frame, and the state data is displayed on a touch display screen. The ship propulsion and power equipment large-scale vibration isolation system centering monitoring device is good in real-time performance, high in measurement accuracy, convenient to use and high in intelligent degree, and can realize real-time high-precision monitoring of the ship propulsion and power equipment large-scale vibration isolation device centering state and raft frame pose.
