城轨CBTC系统与联锁系统功能及接口初步分析

Analysis of Functions and Interface between CBTC System and Interlocking System for Urban Rail Transit

联锁系统作为基础信号设备使用多年,它通过驱动信号机显示来表示可否进入信号机后方防护区段。在高密度、高速度的运营需求下,列控系统得到大量装备,它对列车的安全运行速度与安全运行距离进行防护。对CBTC系统与计算机联锁系统之间的接口进行了初步分析。

As basic signal equipment in railways, the interlocking system has been applied in railways for many years. It is used to drive signals to give signal aspect and indication for trains running in protected section in rear of a signal. Under the demands of high density and high speed operation, train control systems are greatly equipped to protect train operation with a safe speed and safety distance. This paper gives a preliminary analysis of the interface between CBTC system and computer-based interlocking （CBI） system.
