基于仿真技术的信号平面布置验证

传统的城市轨道交通信号系统轨旁设备的布置,主要依赖于系统设计人员的个人经验,其准确度和效率都不能得到有效保障,更多地依赖于后期的现场测试。本文主要针对信号系统设计工作中存在的问题,立足于信号系统设计的完备性和兼容性,建立合肥轨道交通1号线信号系统仿真模型,设计信号系统检验规则库,对1号线信号系统平面布置图进行验证,找出设计方案中潜在的危及行车安全或影响效率的因素,保障信号系统的设计质量,提高系统运营的安全性、可靠性及可用性。

Verification of Signal Layout Based on Simulation Model

The traditional arrangement of wayside equipment of the signalling system in urban rail transit relies on the designers own experience. Thus, the accuracy and efficiency of the design cannot be assured and depends on later field test. To deal with the problems in the design of the signalling system, a simulation model for the signalling system of Hefei rail transit Line 1 has been established for verifying the completeness and compatibility of system design. Meanwhile, a rule base for verifying the design of signalling system is set up. Then, the layout of the signalling system has been verified to seek out potential risks in the design that would compromise the safety of train operation or factors that would impact the efficiency, hence ensuring the design quality of the signalling system and enhancing the safety, reliability and availability of system operation.
