车辆检测传感器可以准确实时获得各种交通数据(包括车流量、车速度、车辆密度、车头距离、占有率等),是智能交通系统(ITS,IntelligentTrafficSystem)中最重要的交通数据采集设备之一。针对道路上车辆检测存在的问题,结合国内外车辆检测器技术的发展状况,使用ARM磁阻传感器,将单片机控制技术和短距离无线传输技术引入到车辆传感器的设计中,从而有效地降低了设备安装的工程量,开发出了适用性更强的车辆传感器。
Vehicle detection sensor can accurately obtain all kinds of traffic data (including traffic flow, vehicle speed, vehicle density, head distance, occupancy, etc.) in real time and is one of the most important traffic data acquisition devices in Intelligent Transportation System (ITS). Aiming at the problem of vehicle detection on the road and the development of vehicle detector technology both at home and abroad, ARM magnetoresistive sensor is used to introduce the control technology of single-chip microcomputer and short-range wireless transmission technology into the design of vehicle sensor, so as to effectively reduce the equipment Installation of the project, developed a more applicable vehicle sensors.
