RFID是近年來(lái)發(fā)展迅速的非接觸式自動(dòng)識(shí)別技術(shù)，為使基于RFID技術(shù)的智能管理系統(tǒng)具有定位識(shí)別的功能，本文提出了多天線空分定位RFID閱讀器的設(shè)計(jì)方案，即采用閱讀器與多個(gè)檢測(cè)天線的分離式裝置，使每個(gè)天線僅識(shí)別自己工作區(qū)域內(nèi)的標(biāo)簽，天線的地
址碼與標(biāo)簽的數(shù)據(jù)共同構(gòu)成傳送的信息，從而使閱讀器具有定位識(shí)別標(biāo)簽的功能。基于本文提出的RFID閱讀器的智能戰(zhàn)備藥箱管理系統(tǒng)可以為戰(zhàn)備藥品提供安全、準(zhǔn)確、實(shí)時(shí)的信息收集、處理和查詢，該管理系統(tǒng)不僅可以提供定位識(shí)別，還可以節(jié)約系統(tǒng)的成本，具有廣闊的應(yīng)用前景。

Abstract: 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 detected 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 intelligent 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 also can debase
system cost. It will have wide application in future.
