摘要
故障占用是计轴系统的故障模式之一,在移动闭塞信号系统中,对运营效率的影响较大。在CBTC系统中,通过ARB的判定来减小计轴区段故障占用对运营效率的影响。ARB判定本身是一个安全关键功能,如果误判ARB,可能导致列车追尾的严重后果。因此,该功能在很大程度上影响着CBTC系统的安全性和可用性。介绍了CBTC系统中ARB判定的一种方法。
Failure occupation is one of the failure modes of axle counting system with substantial affects on the efficiency of operational greatly in the mobile signal system. In CBTC system, ARB function can be used to reduce the effect of operational efficiency from failure occupation. ARB justification is a key safety related function, if the function fails, the consequence maybe crash between trains. So, ARB func- tion greatly affects the safety and availability of CBTC. In this paper, an ARB justification method is in- troduced.
