应用于建筑设备物联网的超高频RFID读卡器设计

摘要

为在建筑设备物联网系统(BECPS)环境中实现人员信息的采集,设计了一个超高频RFID读卡器.首先简要描述了BECPS；其次给出了读卡器的硬件电路、器件选型、系统软件等的设计过程；最后在BECPS平台下对该RFID读卡器进行了实验测试,测试结果证实了该设计方案的有效性.与现有的超高频RFID读卡器相比,该读卡器不仅能够完成多标签识别,并且能够与BECPS完美结合,实现了人员信息的无线上传.%In order to achieve the personnel information acquisition in building equipment cyber physical sys-tems( BECPS), an UHF RFID reader is designed. Firstly, the BECPS is described briefly, and then, the design of hardware, device selection and design of system software are given in detail. At last, in order to validate the UHF RFID reader, a series of tests are performed. The test results show that the UHF RFID reader is feasible. Compared with the existing RFID reader, the proposed UHF RFID is not only able to complete the multi-tag i-dentification, but also can work and upload the personnel information by wireless networks perfectly in the BECPS environment.
