摘要
目的:设计多天线空分定位RFID阅读器,使基于RFID技术的智能管理系统具有定位识别的功能。方法: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,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。结果:将基于多天线空分定位阅读器的RFID系统应用于战备药品的管理,可以为战备药品提供安全、准确、实时的信息收集、处理和查询等功能。结论:该多天线空分定位阅读器不仅可以提供定位识别功能,还可以节约RFID系统的成本,具有广阔的应用前景。
Objective To design Radio-Frequency Identification （RFID） reader with multi-antennas of different spatial location. Methods Design scheme of RFID reader with multi-antennas of difference spatial location was presented, i.e. a separated setting with a reader and multiple detected antennas was adopted. Each antenna only identified tags in its own area. The receiving information from tags contains antenna code and data in tag＇s IC. Hence the reader can point the tags position through different antenna code. Results The application of RFID with multi-antennas of different spatial location to management system of combat readiness medicine can provide safe, exact and real-time information collection, processing and query for combat readiness medicine. Conclusion The system can not only provide location identification, but also reduce system cost. It will have wide application in future.
