摘要
依靠成熟的RFID读写技术,通过与光电开关的结合,巧妙地避免了两个RFID读写头对一个标签进行同时读写,需要实现数据在两套PLC间的交互问题。该方法整个结构简单,控制方便,系统通讯可靠稳定,并可变换成多种结构。
Depended on the mature RFID technology and combined with photoelectric switches, simultaneous reading and writing on one label by two RFID read-write head was avoided intelligently, which needs real-time data interaction between two PLC processors. The system has simple structure and is easy to control. Its communication is reliable and stable, and can change into different structure.
