摘要
车辆管理自动识别中常常会遇到“邻道干扰”问题。所谓“邻道干扰”,指一个车道上的RFID读写器除了读到本车道上的电子标签外,还误读到了邻车道上的电子标签,影响到鉴别各自归属。当有多个并行车道需要安装多个RFID读写器时,若仅仅各自直接读取电子标签,就很难避免这样的“邻道干扰”和“误读”。本文提出了UHFRFID技术在车辆管理应用中所遇到“邻道干扰”问题的解决方法,并在实际工程中取得了良好的效果,对其它应用也可供参考。
Automobile aotu-ID always runs into problem of 'disturbance between neighboring traces' . The so-called 'disturbance between neighboring traces' refers to RFID' s reader not only reads information stored within the e-tag of one trace but also mistakenly read information of e-tag of its neighboring trace, directly causing it not to work normally, not distinguishing information what belongs to. When many parallel traces need to set up many RFID readers, and if they directly read their own e-tags, it is rather difficult to avoid disturbances. This article mentions how UHF RFID technology solves the problem of 'disturbance between neighboring traces' in automobile aoto-ID management and glorious achievements in the application, and give references for other applications.
