汽车数字化标准信源系统识读距离仿真

Simulation on Read Range of Vehicle Digital Standard Information Source System

为实现汽车数字化标准信源系统的采集基站建设和标签安装的最优配置,对无源射频识别(RFID)车辆身份管理系统的识读距离进行了仿真计算。在读写器天线与标签天线远场图确定的条件下,对采集基站的架设参数,例如天线的安装倾角,仿真计算得到目标车辆通过固定式龙门架无源RFID采集基站时的可识读距离,并进行比较分析。为汽车数字化标准信源系统不同车型的标签安装位置以及采集基站的架设提供了参考依据。

This paper describes a simulation calculation of the read range of passive RFID tag in vehicle management system,this system could ensure the optimized configuration in construction of information base station and installation of RFID tag of the vehicle digital standard information resource system.The read distance when the object vehicle passes bythe fixed RFID information capturing systems installed on portal frames is simulated.The read distance for variable structural physical parameters of information capturing base station,the inclination angle of reader antenna for example,in condition of the confirmed farfield pattern of reader and tag antenna iscompared andanalyzed.It provides the referencesupport for the attachment positions of RFID tags on different types of vehicles and the installation of RFID information capturing system devices for the vehicle digital standard information resource system.
