Research on Vehicles Detecting System Based on Geomagnetic Sensor

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 detecting 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.
