摘要
智能交通系统是缓解城市交通堵塞状况、提高交通效益的必由之路。以监测汽车闯红灯为实际出发点,提出一种基于无线电子身份证的汽车监测系统的总体设计方案。方案设计出一种安装在汽车上的无线ID装置,利用地面接收传感器探测汽车的车牌信息,并通过RS-485通信方式发送给以ARM处理器为核心的数据处理装置,从而高效、准确地识别出违规车辆。此外,系统还可通过以太网与城市的交通管理中心进行交互,实现城区交通自动化监测,同时也为扩展新的智能交通管理功能提供基础。
The intelligent transportation system is the necessary way to handle the problems of traffic jam and to improve the efficiency of transportation system.The paper put forwards a general design of transportation detecting system based on wireless electronic identification and shows its use in detecting the running red light vehicles.A wireless ID is fixed on each vehicle and the detectors on the ground can detect the signal and send it thrcugh RS-485 to the data processing system based on the ARM processor,thus it can pick out the illegal vehicles correctly and efficiently.In addition,the system can communicate with the city transport control center through Ethernet,thus can monitor the transportation automatically and provide a base for new intelligent functions.
