摘要
为解决城市车辆拥有量大、停车位资源稀少、居民停车难等问题,基于地磁测量的停车位检测与管理是当前研究的热点问题。车辆对地磁场的扰动及其地磁场的变化特点,是解决该问题的基础和关键问题。本文通过磁阻传感器完整测试了不同车型底部及其周围地磁场三轴分量的分布与变化情况,并通过MATLAB软件分别绘制出不同车辆底部及其周围地磁场变化的三维图,直观地显示了车辆不同位置对周围地磁场的扰动情况,其结果对研究停车位检测具有重要参考价值。
In order to solve the problems of large ownership of vehicles,scarce parking spaces,and difficulty in parking for residents in the cities,geomagnetic measurements based parking space detection and management is a hot topic of current research.The disturbance on the geomagnetic field by the vehicles and the characteristics of geomagnetic changes are the basis and key issues to resolve the problem.In this article,magneto-resistive sensors are used to fully test the distribution and changes of the bottom of different model of vehicles and the three-axis component of their surrounding geomagnetic field,We can obtain three-dimensional views using Matlab about the geomagnetic field variation of different vehicles＇ bottom and surrounding,visually demonstrating the disturbance of the magnetic caused by the different regions of the vehicle,which has important reference value for research on detecting parking spaces.
