一种高速铁路衔接站点灭灯进路联锁软件实现方法

摘要

高速铁路信号机的显示采用了新的技术标准,信号机的常态为灭灯,其联锁逻辑与普速铁路有较大不同.尤其在衔接站,逻辑更为复杂.基于站场图形网络的软件架构,采用模块和消息方法,对信号机点灭灯办理进路的联锁软件进行设计,并分析通过进路和组合长进路的典型情况.该方法适用于衔接站常态灭灯和点灯信号机混合布置的情况.对于信号显示,采用基于布尔表达式方法构建显示逻辑并通过另一份软件和数据进行校核.从风险点和防御措施的角度分析软件安全性,认为采用的方法符合产品安全性要求,适合于工程推广应用.%The signal machine display of high speed railway adopts a new technology standard, the normal signal is off and the interlocking logic is quite different from that of the conventional speed railway. Particularly, the logic in the junction station is getting more complex. In this paper, a software architecture based on station field graphics network is adopted,the lighting and light route interlocking software is designed with module and message method, and the complex typical application of pass route and combined route is analyzed. The method is applicable to the junction station. For the signal display,Boolean-based expressions are employed to build the display logic,which is verified through another software and data. The analysis of software security from the point of risk and defense measures concludes that the method meets the requirements of product safety,and is suitable for engineering promotion and application.
