摘要
利用地磁车检器进行停车位检测时,车检器检测轴方向、停车位方向以及地磁场方向之间的角度关系会影响车检器不同轴向的峰值与灵敏度;为了减少因三向角度关系设置不当导致邻车位干扰或对磁场扰动的灵敏度低,该研究基于双轴向地磁车检器,在不同停车位方向下,针对车检器各个轴向进行实验测试;测试得出的最佳轴向保证正向轴高峰值高灵敏度,同时使侧向轴低峰值低灵敏度,可提高车检器检测精度,并减少邻车位干扰问题;研究给出了经验公式,在各地实践中均得到了良好的效果。
When the geomagnetic vehicle detector is carried out to detect the parking,the angular relationships between vehicle detector to detect the axial direction and the direction of the parking and the geomagnetic field,have an influence that the vehicle detector device with different axial have its different peak and sensitivity.In order to reduce the angular relationship between the three settings to the anti-interference of neighborhood parking or low sensitivity to magnetic field disturbances,this study is based on biaxial geomagnetic vehicle inspection,the parking in different directions for each axial vehicle inspection device for testing.It will find the best point to base on biaxial geomagnetic vehicle detector,a different direction of parking for each axial vehicle detector device for testing,and ensuring the positive axis peak and high sensitivity,while the lateral axis low peak and low sensitivity,improving detection accuracy while reducing the interference of neighborhood parking.It shows the empirical formula around the practice,and good results are obtained.
