基于图像识别与OPC通讯的伺服控制系统

Servo Control System Based on Image Recognition and OPC

本伺服控制系统采用Rockwell公司的Controllogix5550型PLC控制器,通过伺服驱动器控制伺服电机的运转,进而控制实验平台的运动。通过图像识别技术实时采集平台运动信息,通过OPC建立VC开发环境与PLC之间的通讯,构成闭环控制系统,完成对实验平台位置和运动速度的实时精确控制。通过本伺服系统可以使学生了解现代伺服控制系统的构成与应用,在实验室建设与教学方面具有很大的意义。主要讨论基于图像识别与OPC通讯的伺服控制系统的构建,并给出一个球体运动定点控制的实例具体说明本系统的实验意义。

The servo control system is based on PLC of Rockwell Controllogix5550,in which servo driver module and servo motor can control the movement of experiment board.Through the technology of image recognition the information of movement is collected.Communication between VC and PLC is established by OPC.The closed loop control system can precisely control the position and velocity of experiment board in time.The servo control system can make students understand the structure and application of modern servo contr...
