本发明公开的基于天线隔离阵列的车辆定位射频识别系统,包括:若干间隔预埋在道路地面内的无源射频识别标签,每一无源射频识别标签包括射频识别标签芯片、标签天线线圈、辅助天线线圈以及连接控制器;以及一固定安装在车辆上的车载阅读器,所述车载阅读器包括射频识别阅读器、阅读器调谐模块、阅读器天线线圈、标签激励阵列单元、激励阵列单元调谐模块以及激励阵列单元控制器。还公开了一种上述的基于天线隔离阵列的车辆定位射频识别系统的定位方法。本发明在采用相同的无源射频识别磁耦合信号频率下,可以使用大尺寸的激励和数据通信天线,从而实现更远的访问距离。

    The invention discloses a vehicle positioning radio frequency identification system based on an antenna isolation array, and the system comprises a plurality of passive radio frequency identificationtags which are pre-buried in the road ground at intervals, and each passive radio frequency identification tag comprises a radio frequency identification tag chip, a tag antenna coil, an auxiliary antenna coil, and a connection controller. The vehicle-mounted reader is fixedly mounted on the vehicle and comprises a radio frequency identification reader, a reader tuning module, a reader antenna coil, a label excitation array unit, an excitation array unit tuning module and an excitation array unit controller. The invention also discloses a positioning method of the vehicle positioning radio frequency identification system based on the antenna isolation array. Under the condition that the same passive radio frequency identification magnetic coupling signal frequency is adopted, a large-sizeexcitation and data communication antenna can be used, so that a longer access distance is realized.
