Optical fiber distributed train monitoring system

Abstract

The invention discloses an optical fiber distributed train monitoring system. The system comprises a rail roadbed and a main railway track arranged at the top of the rail roadbed, wherein a first branch railway track and a second branch railway track are connected with two sides of the main railway track respectively, the main railway track is provided with an interval detecting optical cable outside a station, a station area detecting optical cable with one end connected with the interval detecting optical cable is arranged between the first branch railway track and the second branch railway track, station area annular detecting optical cables are arranged on the station area detecting optical cable and located at the main railway track, the first branch railway track and the second branch railway track, and an interval running train runs on the main railway track. The system has the advantages that a detection front-end device is passive and resists electromagnetic interference, so that the system can still work normally and guarantee running safety of the train under the condition that other electric train control systems cannot work due to outage faults.

Description

technical field [0001] The invention relates to the technical field of train monitoring, in particular to an optical fiber distributed train monitoring system. Background technique [0002] At present, in the railway system, the single-track railway mainly controls the operation of the train and ensures the safe operation of the train through the relay semi-automatic block train control system. However, the relay semi-automatic block train control system can only manually control the entry or exit of the train in the operating interval, and cannot obtain the specific position and operating status information of the train in the operating interval in real time. Therefore, once the train enters the running section, important information such as its specific location and running status cannot be grasped. This is a huge safety hazard for single-track railways, and it is easy to cause major safety hazards such as train rear-end collisions and collisions due to human scheduling er...

Problems solved by technology

However, the relay semi-automatic block train control system can only manually control the entry or exit of the train in the operating area, and cannot obtain the specific position and operating status information of the train in the operating area in real time.

Therefore, once the train enters the running section, important information such as its specific location and running status cannot be grasped. This is a huge safety hazard for single-track railways, and it is easy to cause major safety hazards such as train rear-end collisions and collisions due to human scheduling errors. ACCIDENT
