基于沙盘的城轨控制实验室集中站联锁仿真系统

在城轨控制实验室仿真平台中,集中站联锁系统是保障列车各种作业安全的重要子系统.本文运用UML建模方法和Visio工具,对系统的需求、设计、编程实现和测试过程进行了描述和分析,建立了系统不同设计阶段的可视化模型.选取沙盘上2个典型集中站进行编程实现和测试,验证了运用UML方法对系统建模的正确性,且能够与沙盘联动控制.此外,系统还设计并实现了保护区段和侧面防护,这是地铁联锁系统的独有特点.

Central Station Interlocking Simulation System for Urban Transit Control Laboratory based on sand table

In the Urban Transit Control Laboratory＇s simulation platform, Central Station Interlocking System was a vital subsystem to ensure the safety of train operation. In this paper, UML modeling and Visio were utilized to describe and analyze the demand analysis, frame design, detailed design, programming and testing of the system, visual model for different design phases were built up. Two typical central station in the sand table were selected to program and test, the validity of the System by UML modeling was verified, and the System could be linked with the sand table. Additionally, the overlap and flank protection were designed and implemented, which were unique features for Interlocking System in subway.
