城市轨道交通信号联锁系统数字模拟盘研究

Research on digital analog disk of urban rail transit signal interlocking system

针对轨道交通信号联锁系统测试工作的需求,设计了一种分布式数字信号模拟盘系统。该系统在硬件上采用上位机与下位机分布式设计,提升了系统容量和可靠性;模块化的设计便于用户根据现场情况灵活选配板卡。在软件上采用了注册码+MAC地址验证双重保护机制,具备站场图绘制、CAD图纸转换等功能。该系统在新建轨道交通信号工程施工中提升了模拟试验的覆盖度,简化了操作流程、节省了人工、材料等费用,为模拟盘研究提供了新的探索方向。

Aiming at the requirements of rail traffic signal interlocking system test work,a distributed digital signal simulation panel system is designed.The system adopts the distributed design of the upper computer and the lower computer in the hardware,which improves the system capacity and reliability;the modular design is convenient for users to flexibly select boards according to the site conditions.In terms of software,the dual protection mechanism of registration code+MAC address verification is adopted,and it has functions such as station yard drawing and CAD drawing conversion.In the construction of the new rail traffic signal project,the system improves the coverage of the simulation test,simplifies the operation process,saves labor,material and other costs,and provides a new exploration direction for the simulation disk research.
