摘要: 青藏铁路格尔木南站改造,其列控车载系统需实现Y型股道列车精确定位功能。阐述基于国产化增强型列车控制系统(ITCS)车载系统的仿真测试平台,针对车载定位功能的升级变更,结合车载系统/软件架构实现的关联性,提出完整、有效的影响分析和回归测试方案,对产品质量的提高起到积极推动作用。

关键词: Y型股道列车定位, 卫星导航, 回归测试, 增强型列车控制系统

Abstract: With the retrofitting of Golmud South Station, the train control onboard system of the Qinghai Tibet Railway needs to achieve precise train positioning in Y-shaped track. This paper elaborates on the simulation testing platform for the localized Incremental Train Control System (ITCS) onboard system, aiming at upgrading and changing the onboard positioning function. In view of the correlation between the onboard system/software architecture implementation, a complete and effective impact analysis and regression testing plan is proposed, which plays a positive role in promoting the improvement of product quality.

Key words: train location on Y-shaped track, satellite navigation, regression test, incremental train control system
