精密无级减光器控制系统的上位机实现

The Implementation of the Control System of Precision Stepless Dimmer on the Upper Stage Computer

本文介绍了一种新型减光器的控制系统的上位机实现策略 ,包括通信原理、软件结构。该系统采用VisualC ++6.0提供的串行通信控件MSComm实现上位机与PLC的通信。

In this paper,the realization strategy of the control system of a new type stepless dimmer is proposed,which includes the principle of communication and the software structure.The communications function between PLC and the Upper stage Computer is developed with Microsoft Communications Control-MSComm that provides by Visual C++6.0.In addition,the method may also be used for other similar system and it is a fairly practical and common technology.
