摘要:: 铁路信号机作为指示列车运行状态的重要联锁设备，其点灯系统的运行状态、产生故障时处理的效率对列车的运营十分重要。传统对信号机的分析停留在点灯电路的分析，无论是运营维护人员还是信号设计人员，均未在系统的角度上分析信号机，使得信号机在系统层面的不安全因素易被忽视。为在系统层面分析信号机点灯系统，本文提出一种基于系统论的层次分析法，通过建立定量与定性相结合的分析模型，对信号机点灯系统的构成性与整体性进行分析。并以高速铁路进站信号机为例，验证了所提方法。结果表明，系统层级的影响因素往往容易被忽视。文末利用层次分析法判断矩阵得到权值向量，根据权值向量分别对点灯系统运营维护与设计所应注重的因素进行了说明。

Abstract:: Railway signals are important interlocking devices for indicating the running status of a train. The operation status of their lighting system and the efficiency of fault handling are very important to the operation of trains. The traditional analysis of the signals focuses on the lighting circuit. Neither the operation and maintenance personnel nor the signal designer analyzes the signals from the perspective of a system, which makes the unsafe factors of the signals at the system level be ignored easily. In order to analyze the signal lighting system at the system level, this paper proposes an analytic hierarchy process based on the system theory and analyzes the composition and integrity of the signal lighting system by establishing a model combining quantitative analysis and qualitative analysis. In addition, the proposed method is verified with the home signal of the high-speed railway station as an example. The results show that the influencing factors at the system level are easily ignored. At the end of the paper, the weight vector is obtained using the judgment matrix of the analytic hierarchy process, and the factors which shall be paid attention to in the operation, maintenance and design of the lighting system are explained according to the weight vector.
