地铁运营线路新旧信号系统过渡方案分析

Analysis of Signaling System Transition Plan for Subway Line in Operation

北京地铁2号线自试运行至2008年开通已跨过了36年的历史,早期投入运营的信号系统由于各方面原因已远远无法满足现代地铁高效、稳定、安全运营的需要,急需新的信号系统的取代。在不影响既有运营线路运营的前提下,工程实施中如何顺利过渡是一个值得研究的问题。

Beijing Metro has passed more than thirty years since its commissioning. Early signaling system into operation could not satisfy the need of efficient, stable, and safe operation of the modern subway due to various reasons. It was required that a new signal system should replace the old one. Under the premise of not affecting the operation of existing lines, how to achieve a successful and smooth transition during the replacement has become a worthwhile problem for research.
