中低速磁浮交通运行控制系统车地双向通信设备的研究

介绍中低速磁浮交通运行控制系统（MATC）的构成,阐明ATP子系统关键设备——对称交叉感应环线的结构和主要功能、对称交叉感应环线地面和车载关键设备的工作实现原理以及对称交叉感应环线和车载天线的特殊安装方式。通过车地双向信息的收/发及环线检测滤波,实现中低速磁浮列车车地双向通信、绝对定位和相对位置校正,构建基于对称交叉感应环线车地双向通信的MATC系统,MATC系统已在唐山运行试验示范线完成基于移动闭塞的中低速磁浮列车的运行控制试验。

Train-Ground Two-way Communication Equipment of Low-Medium Speed MATC System

The paper introduces the composition of low-medium speed maglev automatic train control system（MATC）, elaborates the structure and main functions of the symmetrical cross induction loop which is key equipment of its ATP subsystem, working principle of ground and onboard key equipment of symmetrical cross induction loops, and special installation methods of both symmetrical cross induction loops and onboard antenna. Train-ground two-way communication, absolute positioning and relative position correction of low-medium speed maglev can be realized through train-ground two-way message receive/sending and loop detection filter, and the train-ground two-way communication MATC system is constructed based on symmetric cross induction loops, and the MATC system for low-medium speed maglev based on moving block has been tested in a trial demonstration line in Tangshan train factory.
