The invention discloses a redundant light transmission system for rail transit, and relates to the technical field of rail transit light communication systems. The system comprises a pull-in point controller, an intermediate controller, a pull-out point controller, a first photoelectric detector, a second photoelectric detector, an optical cable, a safety fixer and a signal stabilizer. The pull-inpoint controller is installed at the pull-in position of a rail transit station, the pull-out point controller is installed at the pull-out position of the rail transit station, and the intermediatecontroller is installed on one side of the midpoint position of a rail between the pull-in point controller and the intermediate controller; the first photoelectric detector is mounted on one side ofthe rail between the pull-in point controller and the intermediate controller, and the second photoelectric detector is mounted on one side of the midpoint position of the rail between the intermediate controller and the pull-out point controller; through butt joint with a rail transit control system, accurate control over the time and the running speed of a vehicle entering and leaving a stationis achieved, a standby auxiliary function is achieved, the braking operation of the rail transit vehicle is simplified, and the automation degree is improved.

    轨道交通用冗余光传输系统,它涉及轨道交通光通信系统技术领域。它包含进站点控制器、中间控制器、出站点控制器、第一光电检测器、第二光电检测器、光缆、安全固定器、信号稳定器;所述的进站点控制器安装在轨道交通站点的进站位置处,出站点控制器安装在轨道交通站点的出站位置处,中间控制器安装在进站点控制器、中间控制器之间的轨道中点位置一侧;进站点控制器与中间控制器之间的轨道一侧安装有第一光电检测器,中间控制器与出站点控制器之间的轨道中点位置一侧安装有第二光电检测器;它通过与轨道交通控制系统的对接,实现车辆进出站的时间及行驶速度精准控制,且具有备用辅助功能,简化轨道交通车辆的制动操作,提高自动化程度。
