基于单片机的电动执行器控制系统的开发

Control System of Valve Electric Actuating Equipments based on the AT89S52

电动执行器广泛应用于现代工业控制系统中,对阀门进行控制和调节,控制器是电动执行器的核心部件。本文完成了以AT89S52单片机和CDMA无线数传模块DTGS-800为核心的电动执行器硬软件的开发工作。最后对阀门的位置控制以及流量控制都提出了先进、可行的策略。

Valve electric actuating equipments are widely used to operate and regulate valves in modern control system, and the valve electric controller is a main section of the valve electric actuating equipment. The studying and developing of the control system has been made also. And the bus controlling system and the CDMA communicating network are brought to the scheme of the intelligent electronic actuator. Besides, in detail the author analyzed the valve the valve position locating and the compensating of flux characteristic. The whole design is adjusting and running of the instrument feasibly and reliably and the presumed function has been realized.
