多天线空分定位RFID阅读器的设计

RFID是近年来发展迅速的非接触式自动识别技术,为使基于RFID技术的智能管理系统具有定位识别的功能,本文提出了多天线空分定位RFID阅读器的设计方案,即采用阅读器与多个检测天线的分离式装置,使每个天线仅识别自己工作区域内的标签,天线的地址码与标签的数据共同构成传送的信息,从而使阅读器具有定位识别标签的功能。基于本文提出的RFID阅读器的智能战备药箱管理系统可以为战备药品提供安全、准确、实时的信息收集、处理和查询,该管理系统不仅可以提供定位识别,还可以节约系统的成本,具有广阔的应用前景。

Design Of RFID Reader Using Multi-Antennas of Difference Space Location

Radio- Frequency Identification (RFID) is contactless automatic identification technology which is rapidly development lately. In order to intelligent management systems using RFID technology have the ability of location identification, design scheme of RFID reader using multi antennas of difference space location is presented in this paper. It is a separated setting of reader and more de- tected antennas, each detected antenna only identifies tags in its own area. The receiving information from tags contain antenna code and data in tag's IC. Hence the reader can point the tags position through different antenna code. The managing system of intelli- gent box of combat readiness medicine with RFID reader presented in this paper can provide information collection, processing and query with safety, nicety and real time for combat readiness medicine. The system not only can provide location identification, but al- so can debase system cost. It will have wide application in future.
