摘要
阐述了基于磁道钉导航的车辆定位原理;利用磁道钉磁感应强度公式计算磁道钉周围磁场,生成以磁感应强度X和Z方向分量为横、纵轴的横向偏差等值线方程;基于此等值线方程,得到磁感应强度X,Z方向分量数据对所对应的横向偏差的计算方法,并给出实例验证.
The principle of vehicle positioning based on magnetic markers guidance is introduced in this paper. In the positioning process, earth field and other background disturbances must be removed from sensor signals. Using the analytical expression system computing the magnetic induction with Matlab, it is easy to get the distribution of X, Y, Z component of magnetic induction, and gain the lateral deflection isoline equations based on X and Z component which are the horizontal and vertical axis in reference system. Based on the isoline equations, the lateral deflection computation method is put forward. At last, an example is used to validate the method.
