摘要:: 为了加快工业生产中对数据信息的采集与处理，该文设计了一个运用欧姆龙CJ1W-SCU22模块与RFID设备通信的数据处理系统，兼顾采集、处理、存储等过程，通过该串行通信模块上的RS-232端口采用无协议通信方式与RFID设备进行数据的交换。主设备为NJ控制器，从设备为RFID读卡设备，主设备向从设备发送命令帧，从设备向主设备返回响应帧，数据转换为用户需要的字符型数据。同时上位机程序CX-Supervisor实时接收处理完的数据，并存储到ACCESS数据库中。

Abstract:: In order to accelerate the industrial production data acquisition and processing of information, using a paper designed OMRON CJ1W-SCU22 communication module and the data processing system of the RFID device, taking into account the collection, processing, storing and other processes, through the serial communication module The RS-232 port uses protocol-free communication to exchange data with RFID devices. NJ controller as the master device from the slave device sends a command frame as an RFID reader device, the master device returns a response frame to the master device from the device, the data is converted into character data user needs. Meanwhile, the host computer program CX-Supervisor is real-time Receive the processed data and store it in the ACCESS database.
