摘要
叙述了一种基于可编程控制器、人机界面和伺服控制技术的磁性编码检测系统,介绍了其工作原理及系统的软、硬件设计,着重讲述了如何利用PLC的串口控制伺服电机,以及触摸屏画面的设计。该系统将从纸币上检测得到的磁性编码信息与合格产品的编码特征进行比较来判断产品是否合格,具有操作简便、自动化程度高、运行平稳、可靠性高等优点。
A magnetic code detection system based on PLC, HMI and servo controlled technology was described. The operating .principles and soft-hardware design of the detection system were introduced. It elaborated the methods of using PLCS serial port to control the servo motor,and the touch screen design. The system can judge the products qualified or not through comparing the mag- netic code detected from the bank notes with normal code features of qualified products. It has the special characteristics of simplicity of operator, running smoothly, high automated level and high reliability.
