摘　　要：在单车道路段交通系统中利用车辆的磁特性,使用基于微磁传感器的自动检测系统,可以方便、快捷地获取和处理机动车辆的流量和速度信息。本文提出了一种基于微磁传感器的SOP(Sys-tem on PCB)自动检测系统,能可靠地完成机动车辆弱磁信号的检测、信号处理、数据存储等功能。经过实验验证,真正实现了交通管理中车辆检测的无人化和智能化。In terms of the magnetic characters of motor vehicles in single - driveway traffic system, it can obtain and deal with the information of motor vehicles＇flux and speed conveniently and quickly, via using the automatic detecting system based on micro - magnetic sensors. This paper puts forward a kind of automatic detecting system based on SOP （ system on PCB） of micro - magnetic sensor, it can reliably finish the detecting of feeble magnetism signal, signal processing, and data memorizing. By experiment validating, it really realizes unmanned and intelligent manage of motor vehicles＂ detecting in traffic system.
