摘要:
故障-持续运行”是对城市轨道交通信号系统的最高要求，也是基于运营高度对系统安全的理解。在自动化系统不断扩展其功能边界的趋势下，人员介入不再被认为是安全可靠的手段，系统本身应能处理更多的异常。分析了与系统可靠性相关的容错、安全完整性和韧性的概念；将系统韧性理论引入城市轨道交通信号系统设计，采用系统能力损失对系统韧性进行量化计算；建立了韧性系统设计模型，并将该模型应用于智能调度系统设计，使用韧性度量来作为最优化控制目标。仿真验证证明了系统韧性理论和方法在城市轨道交通信号系统设计中的有效性。
Abstracts:
′Fail-operational′ is the highest requirement for urban rail transit signaling system, and also an understanding of system safety from the high-level operation. With the trend of automatic systems expanding their function boundaries, human intervention is no longer considered a safe and reliable means, and the system itself should be capable of treating more anomalies. Concepts such as fault tolerance, safety integrity level and resilience related to system reliability are analyzed. System resilience theory is introduced into the design of urban rail transit signaling system, and system resilience is quantitatively calculated using system ability loss. A design model of the resilience system is established, and is then applied to the design of intelligent scheduling system with resilience measurement as the optimal control target. Simulation verification proves that the system resilience theory and method are effective in urban rail transit signaling system design.
