摘要

鉴于目前在建及拟建的城轨交通项目中，信号系统绝大多数采用基于通信移动闭塞列车控制（CBTC）系统以及大部分城市的CBTC 系统都考虑了适当的后备模式，在结合具体工程实践的基础上，对IATP（Intermittent Automatic Train Protection）后备模式下速度码的分布及各种失效模式下对速度码的影响进行了深入研究，给出了速度码的分布方案并对其进行了详细设计。通过对速度码安全性分析，结果表明该方案满足设计要求。

Abstract

Aim to the present condition that signal system for urban rail transits project mostly was based on moving block train trafficcontrol system (CBTC) and appropriate fallback mode was taken into consideration for the CBTC systems in most cities, distributionprinciple of speed codes and speed codes changes in case of various failure modes under IATP fallback mode was studied with specificengineering practice, and detailed design was carried on for speed codes distribution scheme. With analysis of speed codes safety, the schemewas proved satisfy the design requirements.
