基于串行数据接口的摄像机控制系统设计

Design of the Control System of Vidicon Based on Serial Port

提出了运用计算机串行口发送指定信号来控制步进电动机的方法,并设计出相应的摄像机控制系统,运用VB语言编制出计算机与摄像机的通信程序,并在通信过程中实现了CRC校验,利用VB程序所提供的MSComm控件实现了通过串行通信口控制数字摄像机的缩放、变焦等功能。

This paper put forward a method of controlling stepper motor through computer serial port, and designed a control system of vidicon. Using Visual Basic to achieve the communication program between computer and vidicon, also function of vidicon zoom ＆ focus and CRC verifying were completed by the program.
