铁路集装箱定位数据转换关键技术研究

A Study on the Key Technologies of Data Transformation in Railway Container Location

采用有源定位追踪器对铁路运输集装箱进行追踪已经被越来越广泛地应用。为解决有源定位追踪器所采集的定位数据的转换问题,阐述集装箱定位数据采集及转换流程,研究集装箱定位数据转换关键技术,提出采用有源定位器采集位置信息和第三方基站库基站信息结合的本地基站定位解析库创建方案,采用二次动态纠偏算法提高基站定位数据纠偏的成功率,并通过进路搜索优化算法解决了在交叉或相邻线路区域容易出现纠偏错误的问题,有效地改善了铁路集装箱追踪定位数据的转换和显示效果。

The active location of tracker in railway transportation container tracking is applied widely. To solve the conversion problem of location data collected by active location tracker, this paper expounds the process of collection and conversion of container location data, studies the key technologies of container location data conversion, and puts forward a scheme of creating a local base station location analysis library which combines the acquisition of positioning information by active positioning tracker and the base station information of third party base station database. The secondary dynamic rectification algorithm is used to improve the success rate of base station positioning data rectification, and the route search optimization algorithm is used to solve the problem of error correction in cross or adjacent line areas, which effectively improves the conversion and display effect of railway container tracking and positioning data.
