摘 要: | 为适应高速铁路列控系统接口需求,计算机联锁系统接入信号安全数据网[1]的同时,应用软件需要新增进路模块来实现接口的应用信息交互。进路模块利用原有联锁软件网络化结构的选路原理,实现了进路信息存储;利用进路中道岔的大号码特征,实现符合黄闪黄条件信号显示自动计算。软件采用模块化设计的同时,对软件需求、设计、结构、安全性进行全面分析,确保联锁子系统软件的兼容性和可持续开发性。基于升级的计算机联锁软件不仅满足高速铁路列车控制系统的需求,也提高了原有软件的安全性和可靠性。

Abstract: | To meet interface requirements for high speed railway train control system,the application software needs new route module to realize the interface application information interaction while the signal safety data network is being introduced into the computer interlocking system. The route module uses the routing principle of the network structure of the original interlocking software to fulfill route information storage and employs the characteristics of the large number switch in the route to conduct automatic calculation of the signal display in accordance with the condition of yellow-flashing-yellow.When software modular design is conducted,the requirement,design,structure and security of the software are analyzed in a comprehensive way to ensure the compatibility and sustainability of the interlocking subsystem software. The upgrading of computer interlocking software not only meets the requirements of train control system for high speed railway,but also improves the security and reliability of the original software. |
