RFID Integrated Production Line Control System Based on Field-bus

提出基于现场总线的无线射频识别技术(RFID)与生产线控制系统的集成架构,分析了该架构中RFID数据采集单元的功能组成,开发了具有CAN总线接口的RFID数据采集单元,建立了一个基于CAN总线的RFID生产线集成控制实验系统。与现有的RFID在生产线上的应用相比,该系统结构简单,RFID标签所承载的信息更加丰富,信息交互更为直接、快捷,具有更高的可靠性和实时性。

This paper presents a field-bus based architecture of RFID integration with production line control system, and analyzes functions of the RFID acquisition processor in the architecture. Then a RFID acquisition processor with CAN（Control Area Network） interface is developed. After that, a production line control system which integrates RFID by CAN bus is built. Compared with traditional RFID applications in production line control, the system architecture is simpler, the information carried on tag is more abundant, and the data exchange is more direct and quicker. The experimental results show that the RFID integrated production line control system based on field-bus possesses high reliability and good real-time performance.
