摘　　要：基于地磁传感器的车辆检测系统通过检测道路车辆通行情况,可以用于城市道路交通的控制与管理,以提高城市道路的通行能力、缓和城市交通拥挤状况。整个系统分为计算机、中继器和检测节点3个部分,采用新型的地磁传感器监测道路上车辆通行信息,通过串行方式进行模块间的通信。模型实验结果表明:利用该系统,可以实现车辆通行状况的检测,并将信息传输至计算机进行存储和路况模拟。The traffic situation is detected by the vehicles detecting system based on geomagnetic sensors, which can be used in control and management of the road transportation. That urban road＇s traffic capability is sharpened and the municipal transportation crowded condition is relaxed. The Overall system was divided into the computer, the repeater and the detecting nodes. In the detec- ting nodes, the geomagnetic sensor was used to monitor the traffic information, and serial communications mode was adopted between modules. The model experimental result indicates that this system can be used to detect the traffic condition, and the information transmitted tO computer can be used to store or simulate the road states.
