摘　　要：提出了一种基于PXA270平台支持多现场总线的RFID中间件系统,论述了硬件系统和软件框架的设计方案。通过标准串口和网口连接前端多种类型的RFID读写器,在获取数据之后,利用中间件技术对其进行规范化处理,最后经多现场总线(CAN、PROFIBUS、RS485、RS232、Ethernet)与上层设备相连,从而屏蔽了不同读写器数据格式的差异。在实际RFID工业系统中的应用表明,该设计系统具有良好的适应性。Based on PXA270 platform supporting multi-fieldbus, a new radio frequency identification （RFID） middleware is designed. The architecture of the hardware system and the framework of its software system are discussed. The RFID middleware links various readers by using standard serial ports and Ethernet, normalized the data receiving from the readers based on the middleware technology and connects upper devices by using multi-fieldbus such as controller area network （CAN）, process field bus （PROFIBUS）, RS485, RS232 and Ethernet finally. Consequently, the RFID middleware shades the differences between data formats receiving from all kinds of Readers. Application result in RFID industry system shows that the middleware system designed has good adaptability.
