基于SI4421和GPRS技术的车辆身份识别系统

Research of vehicles ID system based on SI4421 CMOS chip and GPRS techniques

针对校园小区门口、高速公路收费站等处车辆通过缓慢的问题,结合射频识别(RFID)技术的特点,分析了车辆识别并快速通过的方法,提出了一种以远距离有源射频识别和GPRS技术为基础的车辆身份识别系统的实现方法.主要给出了相关硬件和部分软件实现方法.经测试有很好的效果,应用前景较好.

In view of the problem that the vehicles go through the at the campus gate or the highway toll station too slowly,combining characteristics of the radio frequency identification（RFID） techniques,this paper analyzed the methods that the vehicles identified and go through the gate quickly,and presented a new realization method of the vehicle could be identification system based on the long-distance active RFID and the GPRS techniques.The implement method of the hardware and the partial software were given in this paper.The system had given the good performance in the test.
