高速铁路运行试验列车追踪间隔测试体系研究

Study on the Headway Test System for Operation Test of High Speed Railway

高速铁路列车追踪间隔测试是在联调联试及运行试验阶段,验证新建高速铁路是否满足线路通过能力设计的一个重要测试项目。借鉴以往追踪测试实践经验,剖析追踪测试场景设计的影响因素,分析采用TAX箱通讯卡和高精度GPS进行运行数据采集的有效性。从列车出发追踪间隔卡控、列车运行速度控制、列车区间追踪间隔调控、测试项点分析等方面,研究列车追踪间隔测试过程控制。在此基础上,研究二分查找与信号影响时间补偿相结合的测试分析方法,提出一套完整的高速铁路运行试验列车追踪间隔测试体系,为列车追踪测试提供参考和依据。

The headway test for high speed train is an important test item to verify whether the newly-built high speed railway meets the design requirement of track carrying capacity in the phases of integration test and commissioning as well as trial operation. This paper analyzes the validity of the data collection via TAX box communication card and high precision GPS by referring to the previous test experience and discussing the influencing factors of scenario design for headway test. The paper studies the headway test process control from the aspects of headway control for train departure, control of train operation speed, headway regulation related with sections, and test item analysis, etc. Based on what is mentioned above, this paper analyzes the test analysis method combining binary search and signal influence time compensation and proposes a complete headway test system for the operation test of high speed railway, providing references and evidence for headway test.
