摘要
利用射频识别技术,采用RS485协议,通过PLC CP341模块与射频识别装置之间的串行通信,实现了对焦炉炉号的准确识别。该方法同样也可以运用到PLC与采用RS485总线的现场智能仪表之间的通讯。
Taking the technique of RFID and RS485 protocol, through serial communication between PLC CP341 model and RFID appliance, oven-number identifying precisely on coke oven is accomplished. The method can also be applied to communication between PLC and field intellective instrument which adopts RS485 bus.
