摘要
介绍了一种基于轨道电路固定闭塞模式,在不改变原有系统地面设备的情况下,采用增量更新方式,升级为目标-距离模式列车自动防护ATP信号系统;介绍了目标距离模式ATP系统原理,与固定闭塞模式的区别,实现增量更新升级的改造方式;最后阐述采用此模式进行系统升级改造,在节省投资,减少对运营影响方面的积极作用。
This paper introduces a kind of fixed block model based track circuit,which adopts incremental updating mode to upgrade into target-distance ATP signaling system without changing existing wayside equipment.This paper introduces the principle of target-distance mode of ATP system and the differences from fixed block mode and the way of how to achieve incremental updates.Finally,it elaborates how to upgrade a system using this mode to save investment and reduce the effect of upgrading on operation.
