摘要
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,该方法具有不受温度、风雨等自然条件影响的优点。文章给出了实际测量电路,进行地球弱磁场下车辆检测试验。实验数据表明AMR传感器应用在停车场车位检测等领域具有一定的优势。
A method based on anisotropic magnetic resistance sensor (AMR) for vehicle detection is put forward in this paper. This method can work from the influence of temperature, wind and other natural conditions. A practical measuring circuit is presented and the vehicles tests under the condition of weak magnetic field are completed. Experimental data show the superiority of AMR sensor in parking detection application.
