摘要
针对现代数字化车辆信息检测的要求,提出了一种采用各向异性磁阻传感器(AMR)进行车辆检测的方法,利用2个各向异性磁阻传感器组成的三轴测试电路,应用基于阈值的车辆判别方法,在地球弱磁场下进行车辆检测试验.通过对磁阻传感器采集的数据进行分析和处理,结果说明AMR传感器应用在停车场车位检测等领域具有一定的优势.
For the purpose of requirements of the modern digital vehicle information detection,this article proposed a use of anisotropic magnetoresistive sensor （AMR） for vehicle detection. The triaxial test circuit was composed by two anisotropic magnetoresistive sensors. Vehicles distinction method which based on threshold value was applied,and the vehides experiment was carried on in the Earth＇s weak magnetic field. Through the analysed and processed of the data collected by magnetoresistive sensor,it indicated that AMR sensors have advantage in many fields such as parking spaces detection.
