Abstract: In the Chengdu-Chongqing high-speed railway upgrading project, skylight times are used for tests by sections without affecting the transportation. In this paper, through analysis and discussion of train control data table and permitted speed table of engineering line provided by design, the train control software, RBC software, temporary speed restriction software and balise telegram that need to be modified in this project are sorted out. The tests are performed using the temporary speed restriction scope, and the whole system is put into operation at once finally. The operation speed of Chengdu-Chongqing high-speed railway has been increased to 350 km/h after the project. It provides reference for the follow-up high-speed railway upgrading projects.

Key words: high-speed railway, interlocking, train control system, track circuit, signaling system

摘要： 成渝高铁提质达速工程，在不影响运输下，利用天窗点分段试验。利用设计出具的列控数据表及工程线路允许速度表，通过分析讨论，梳理工程需要修改的列控软件、RBC软件、临时限速软件、应答器报文。在临时限速管辖范围内进行分段插入试验，最后一次性开通。工程改造后成渝高铁运营时速将提高到350 km，为后续高速铁路提质达速改造工程提供借鉴作用。
