摘　　要：在CCD技术的基础上,根据生产线在线检测的原理及误差,提出了在线检测的机械传动系统和计算机控制系统,并对检测系统的光源、执行机构和控制元件等进行了分析研究。控制系统采用的串口通信是工业控制中常用的通信方式,运用VB.NET编写上位机程序,并利用Serial Port类实现与下位机进行串口通信。通过对光电开关和步进电机控制原理进行研究,设计出一种合适的光电开关接线电路以实现精确控制。将实验室样机试验中出现的问题进行了分析总结。According to the principle and error of the production line detection, the on-line mechanical drive system and computer control system are proposed on the basis of CCD technology.And the light source, actuators and control element are analysed and studied.The serial port communication in this system is commonly used communication mode in the in-dustrial control. VB. NET is used to write PC program and the SerialPort class is applied to the implementation and fulfil ment of the communication. According to the control principle of the photoelectric switch and stepper motor, the circuit for the photoelecfric switch is desighed to realize the accurate control. The problems arising from the laboratory prototype test are analyzed and summarized.
