摘要
数字轨道电路是城市轨道交通准移动闭塞中的基础设备,是自动列车保护(ATP)系统中的基本组成部分,和基于无线通信的信号系统相比,具有稳定可靠、对维护人员要求低的特点。列车自动控制系统(CBTC)移动闭塞没有出现前,它在轨道交通信号系统中占有很大比重。文章以哈尔滨1号线采用的日本株式会社京三制作所的数字轨道电路为例,介绍ATP子系统架构、ATP子系统主要功能、数字轨道电路的工作原理、轨道电路的发送信息和检测距离。
The digital track circuit is urban rail transit quasi moving block in infrastructure,is the basic composition of ATP system.Compared with the signal system based on wireless communication,it has the characteristics of being stable and reliable,low requirements for maintenance,and has a large proportion in the railway traffic signal system before CBTC moving block appear.Harbin Metro Line 1adapts the Kyosan Companys track circuit system in Japan.This paper introduces ATP subsystem architecture,ATP subsystem main function,digital track circuit working principle,and the distance track circuit receives and sends information.
