摘要: CTCS3-300T列控车载系统核心控制模块采用双套冗余方式, 但在列车接口环节,系统使用单套DX/DI接口单元,形成单一失效节点,容易导致黏著性故障。为解决单套DX/DI对CTCS3-300T系统可用性的影响,提出使用冗余列车接口的优化设计方案,使用双套冗余DX-TH替代单套DX/DI模块。该方案不占用额外安装空间,不破坏既有CTCS3-300T其他子模块的安装空间完整性。可靠性模型分析表明, 使用冗余DX-TH模块可有效提升CTCS3-300T系统的可靠性。

Abstract: The core control module of CTCS3-300T train control on-board system adopts double sets of redundancy. However, in the train interface link, the system uses a single set of DX/DI interface unit, forms a single failure point, which is easy to cause adhesive failure. In order to solve the impact of a single set of DX/DI on the availability of the CTCS3-300T system, an optimized design scheme using redundant train interfaces is proposed, double redundant DX-TH modules are used instead of single DX/DI modules. This solution does not take up additional installation space and does not jeopardize the integrity of the installation space of other sub-modules of the existing CTCS3-300T. Reliability model analysis shows that the use of redundant DX-TH modules can effectively improve the reliability of the CTCS3-300T system.

Key words: CTCS3-300T, train interfaces, redundancy, single point of failure
