RFID和Zigbee技术在实验室设备定位管理中的应用

Application of RFID and Zigbee Technology in Laboratory Equipment Positioning Management

针对高校生物实验室大多依靠人力管理的不足之处,和实验品频繁使用带来的巨大安全隐患问题,基于RFID技术和Zigbee自组网无线传输技术,设计了由RFID电子标签、RFID阅读器、Zigbee终端节点、Zigbee协调器网关等组成的实验品门禁管理和定位跟踪系统。重点阐述了基于RSSI接收信号强度的定位跟踪系统,搭建了Zigbee自组网无线网络,给每一个已知位置的RFID阅读器都配备一个Zigbee终端节点,以便把RFID阅读器识别定位到的待测电子标签数据通过Zigbee网络实时传到上位机。经测试,该系统可以实现实验品定位跟踪和门禁管理,为生物实验室安全管理提供了一种实用的技术管理手段。

As for those problems of most biological laboratories in universities, including the more dependence on human, the lack of institutional management as well as the huge safety hazards caused by the frequent use of experimental products, based on RFID technology and Zigbee self-organizing network wireless transmission, it designs access control management and positioning system for those experimental products, which are composed of RFID electronic tags, RFID reader, Zigbee terminal node and Zigbee coordinator gateway. This paper focuses on the locating and tracking system deprived from a received signal strength(RSSI). It builds a Zigbee self-organizing network wireless network to equip a Zigbee terminal node for each RFID reader with a known location, so as to upload the electronic tag data to be measured which is identified and located by RFID reader to the host computer in real time through the Zigbee network. According to verification test, this system can realize the automatic positioning and access control management of experimental products, providing a practical technical management means for the safety management of biological laboratories.
