摘要
为了安全、高效地实现城市轨道交通信号系统的升级改造,从信号系统改造面临的形势和任务、相关设计标准、总体技术原则、主要难点和制约因素等方面出发,为适应不同的项目情况制定了3个技术方案;针对信号系统升级改造过程中遇到的车载信号适应性难题,以及延伸线路与既有线路设备的寿命差异问题进行了剖析,指出需加快互联互通车载信号系统的研发和推广,以及信号系统升级改造标准的制定。
To conduct the upgrading and transformation of signal system of urban rail transit in a safe and efficient manner, three technical schemes applicable for the transformation of the signal system in different projects are proposed based on the present situation and tasks facing the transformation of signal systems in urban rail transit, involving relevant design standards,overall technical principles, major difficulties and constraints. Especially, the adaptability problems of on-board signal encountered during the process of project transformation and the discrepancies between the life span of the equipment in the extension line and that of the existing line are expounded. In addition, it is pointed out that the research and development as well as promotion of interconnected vehicle signal systems should be quickened and the establishment of the standards for upgrading and transformation of signal system in urban rail transit should also be speeded up.
