| 摘 要： | 基于某既有CTCS-3级列控系统高速铁路GSM-R系统动态检测工作,阐述检测中发现的主要问题及其调整优化。为恢复按设计速度运营而进行的高速铁路GSM-R动态检测,能够发现并解决的主要问题是列控运行控制类电路交换数据业务(CSD)服务质量检测指标劣化;探讨检测列车在不同运行方向、不同车体朝向时检测数据存在的差异,并设置专项试验场景分析数据差异的规律,提出改进检测方案的合理化建议。

| Abstract: | In line with systematically dynamic inspection of existing high speed railway (HSR) GSM-R controlled by CTCS-3, the paper introduces main problems found during the inspection and corresponding adjustment and optimization. Dynamic inspection of existing HSR GSM-R aims to make train operate at design speed, through which the main problem found is the degradation of service quality inspection index of train operation control combined service drawing (CSD);the paper also discusses the data deference of detected train at different operation directions as well as different car-body orientations, analyses the rules of the deference in special test scenarios and puts forward reasonable suggestions to improve detecting schemes. |
