The invention discloses an urban rail transit train positioning method based on distributed optical cables, belongs to the technical field of traffic train positioning, and aims to solve the problems that in an existing urban rail transit train positioning mode, due to the fact that the position of a transponder is discontinuously arranged, continuous positioning is difficult, and a train cannot be accurately positioned. Comprising the following steps: step 1, arranging train positioning equipment including light source equipment, OTDR (Optical Time Domain Reflectometer) equipment, optical detection equipment, a distributed optical cable and an intelligent analysis host at each signal concentration station and section site of a subway; and step 2, the distributed optical cables are laid to the rail-mounted area from the signal equipment rooms of the signal concentration stations and the signal equipment rooms of the signal concentration stations and the signal equipment rooms of the signal concentration stations and the signal equipment rooms of the signal concentration stations and the signal equipment rooms of the signal concentration stations and the signal equipment rooms of the signal concentration stations. According to the invention, real-time positioning of the train is realized by laying the distributed optical cables under the train operation track, and accurate positioning of the urban rail transit train can be realized.
本发明公开了一种基于分布式光缆的城市轨道交通列车定位方法,属于交通列车定位技术领域,旨在解决目前城市轨道交通列车定位方式由于应答器的位置是非连续设置,难以连续定位,列车无法精确定位的问题。包括如下步骤:步骤1:在地铁各信号集中车站、段场处所设置列车定位设备,包括光源设备、OTDR设备、光探测设备、分布式光缆、智能分析主机;步骤2:分布式光缆分别由各信号集中车站及段场信号设备室敷设至轨行区,信号集中车站/段场敷设的分布式光缆覆盖范围仅包括本信号集中车站/段场的管辖范围。本发明通过在列车运行轨道下敷设分布式光缆实现列车实时定位,能够实现城市轨道交通列车精确定位。
