Research on the Automatic Electronic Map Generation Algorithm for the Train Supervision System

GPS是近年来得到广泛应用的定位系统,将先进的定位技术应用于铁路站场可实现调车的可视化、智能化监控,有利调车安全,提高调车效率。但是车站股道密集的特点决定了对定位数据高精度的要求,生成一张精确的电子站场图成为实现列车智能化监控的一个必要环节。本文针对调车作业产生大量重复轨迹的特点提出多轨迹融合的方法实现地图自动精确化和更新,并且对定位测量方法及弯轨的表示进行了讨论。初步的实验结果证明了算法的有效性。

GPS is the positioning system with powerful function widely used in recent years. Applying the advanced positioning technology to railway marshalling yards can realize the visual and intelligent surveillance over train dispatching, eliminate the potential problems in the safety of running trains and improve the dispatching efficiency remarkably. For the trains to run among the dense tracks in marshalling yards, utmost accurate positioning is required. To generate an accurate electronic map of a marshalling yard becomes an essential link to realize intelligent surveillance over the train dispatching process. A multi-track fusion algorithm to realize the automatic refinement and update of the electronic map is proposed by utilizing the repetitive and redundancy track data of the running trains. The method of positioning survey and presentation of track curves are also discussed. Preliminary experimental results prove the effectiveness of the proposed algorithm.
