摘要:
城市轨道交通信号的联锁系统是保障列车运行安全的核心设备，根据安全防护条件和时序实现进路、信号和道岔之间联锁控制，满足列车安全运行的需求。分析了在大客流、高密度及超大网络的形势下，联锁系统作为信号系统安全最后一道防线所面临的发展需求。基于安全防护机理，结合当前信号系统故障安全持续运行的发展方向，从联锁系统的安全效率平衡、全自动化运行适配及互联互通等方面分析了联锁系统的未来发展趋势。从联锁系统的安全理念、功能、形式和控制方式等方面阐述其演变要求，即：从“小联锁”向“大联锁”转变，从“硬联锁”向“软联锁”转变。
Abstracts:
Urban rail transit signal interlocking system is the core equipment ensuring train safe operation by realizing interlocking control among routes, signals and switches according to safety protection conditions and sequences, fulfilling requirements of train safe operation. Under the situation of massive passenger flow, high operation density and super-large-scale network, the development requirement faced by interlocking system as the last defense of signaling system safety is analyzed. On the basis of safe protection mechanism, considering the development direction of current signaling system of fault-safety-operation, the future development trend of interlocking system is analyzed from perspectives including safety-efficiency balance, automatic operation adaption and interoperability. The development requirements are illustrated from the perspective of safety concept, functionality, format and control method, also as Narrow-sense Interlocking to Broad-sense Interlocking, from Hardware-based Interlocking to Software-based Interlocking.
