基于RFID技术的动态数据采集系统设计

Design of Dynamic Data Acquisition System Based on RFID Technology

为了实现汽车车门生产过程的可追溯性,以便对汽车车门的质量和数量进行有效监测,以某汽车厂车门生产线为研究对象,根据射频识别(RFID)技术设计了动态数据采集系统。首先,设计了上位机管理系统。然后,采用应用于过程控制的对象连接与嵌入(OPC)协议建立Kepserver与可编程逻辑控制器(PLC)之间数据联系,并利用西门子S7-1200 PLC控制欧姆龙V680S读写器对标签数据的读写。最后,将实时数据反馈给上位机。动态数据采集系统融合了OPC协议与Modbus协议,实现了西门子PLC与欧姆龙V680S读写器和上位机之间的通信。系统测试表明,该数据采集系统实时性较好,运行稳定,定位精准度较高。该系统操作简便、实用性强,对实现工业生产自动化有着重要的意义。

To achieve traceability of the automotive door production process for effective monitoring of the quality and quantity of automotive doors, a dynamic data acquisition system is designed based on radio frequency identification(RFID) technology for the door production line of an automotive plant as the research object. Firstly, the host computer management system is designed, and then the object linking and embedding for process control(OPC) protocol is used to establish the data connection between Kepserver and programmable logic controller(PLC), and the Siemens S7-1200 PLC is used to control the Omron V680 S reader to read and write tag data. Finally, the real-time data is returned to the host computer. The dynamic data acquisition system combines OPC protocol and Modbus protocol to realize the communication between Siemens PLC and Omron V680 S reader and the upper computer. The system test shows that the data acquisition system has good real-time performance, stable operation and high positioning accuracy. The system is easy to operate, practical, and has important significance to realize industrial production automation.
