基于RFID技术的小区车辆无线管控系统中，RFID技术作用距离短，需要停车刷卡验证，而基于Zigbee等无线技术的小区车辆无线管控系统，作用距离相对较远，但无线电波的无向性不便于判断车辆的进出状态。针对该矛盾，给出了基于定向天线技术的小区车辆无线管控系统，通过定向天线的指向性，合理设置出入口无线检测器的安装位置，可以使得出检测器和入检测器独立、互不干扰地分别检测车辆的出和入，实现车辆身份的验证、停车费用管理等功能。
基于RFID技術的小區車輛無線管控繫統中，RFID技術作用距離短，需要停車刷卡驗證，而基于Zigbee等無線技術的小區車輛無線管控繫統，作用距離相對較遠，但無線電波的無嚮性不便于判斷車輛的進齣狀態。針對該矛盾，給齣瞭基于定嚮天線技術的小區車輛無線管控繫統，通過定嚮天線的指嚮性，閤理設置齣入口無線檢測器的安裝位置，可以使得齣檢測器和入檢測器獨立、互不榦擾地分彆檢測車輛的齣和入，實現車輛身份的驗證、停車費用管理等功能。

In the wireless management system of residential district vehicles based on RFID technology,the distance covered by RFID is relatively short,car owners have to stop for identity authentication.Though the radio coverage of the management system of residential district vehicles based on wireless technologies such as Zigbee,etc.is comparatively long,it is inconvenient to judge the vehicles’ states due to the isotropy of radio wave.Considering this contradiction,a wireless management system of residential district vehicles based on directional antenna technology is proposed in this paper.If the wireless entrance-detector and exit-detector are fixed properly,they will detect vehicles entering or leaving independently as a result of the directivity of directional antennas.The identity authentication of each vehicle and management of parking fee can be achieved.
