Probability-based base station position anomaly detection and relocation method

The invention relates to the technical field of indoor positioning, in particular to a base station position anomaly detection and repositioning method. The invention aims at all base stations of a system. The method comprises the following steps: firstly, distance information between base stations is acquired by using a routing table and a time difference method; then the base station is detectedby using a probability-based method, the base station with abnormal position is determined, and finally the abnormal base station is repositioned by using the cosine law, so that the base station with abnormal position capable of improving the label positioning accuracy is detected and repositioned. 本发明涉及室内定位技术领域，特别是一种基站位置异常检测及重定位方法。本发明针对系统所有基站，首先使用路由表和时间差的方法来获取各基站之间的距离信息，然后使用基于概率的方法对基站进行检测，确定位置异常基站，最后使用余弦定理对异常基站进行重新定位，实现了能够提高标签定位准确度的位置异常的基站检测与重定位。
