Developed Based On Dsp-rel Inverter Electric Actuator

Electric actuator is important equipment in valve control and an indispensable basic unit to constitute the control system. To realize the intellectualized electric actuator is the trend development of valve control system. But the most of our country used is inports. It is very important to design electric actuator ourselves because of high price.This text according to system total design request put forward the design plan of modular. The different functional requirement that aims at each modular and consider system applied bad work condition, carrying on the analysis of the system and designing. This topic began to develop double CPU electrically operated implementing agency section which based on the technical as DSP, frequency conversion, infrared remote control and so on. This control system not only increased control precision, the stability and the reliability of the electrically operated implementing agency greatly, Also causes the operation of the system simply, to be safe.The power supply module provides the control circuit, the drive of frequency conversion circuit, transaction circuit and DSP with different power supply. The mode choice module makes the conversion of long-distance, on the sport and stop and the switch of the direction of the electromotor come true. The opening detecting and transaction module, the moment detecting and transaction module detect system at any moment. It assures that operate of system security and calm. The remote control module controls the opening of valve by simulant signal. It also controls the open and the close of the valve by on-off signal. The LCD module shows parameters and the state signal of system.
