Abstract

The invention discloses a safe running method and a safe running system based on an intelligent optical fiber sensing technology and E-shaped and reverse E-shaped leaky coaxial cables. By the method, the running safety is improved by a vehicle-ground bidirectional communication system (the bit error rate is less than and equal to 10<-6>) formed by the intelligent optical fiber sensing technology, an intelligent judgment processing center (a train control center), the E-shaped and reverse E-shaped leaky coaxial cables, a vehicle-mounted antenna and the like; train positioning information, positions of all trains in the whole running command interval, distances, running speeds, and the optimal running speeds of the trains can be accurately acquired; and the distance between front and rear trains, real-time speeds and the optimal running speed of the train can be displayed by the train-ground communication system, so that the safety of vehicles running on subways, railways and high-speed railways can be improved, the transportation efficiency of the vehicles running on the subways, the railways and the high-speed railways is improved. Besides, the intelligent optical fiber sensing technology is free from external electromagnetic interference, so that the critical technical problem that railway signals are thunder-struck can be completely solved; and the cost of the trains in each kilometer is only 20 percent that of the C3 system of the conventional high-speed trains, so that extremely great social benefits and economic benefits are gained.

Description

technical field

[0001] The invention relates to a safe driving method and system based on intelligent optical fiber sensing and positive and negative E-shaped leaky cables, belongs to the technical field of combining information communication, optical fiber technology and driving control, and is especially suitable for the integration of communication signals of subways, railways and high-speed railways Advanced driving control system. Background technique

[0002] The optical fiber sensor network will be an important part of the Internet of Things, but the vehicle-to-ground communication system (bit error rate less than 10 -6 ) combined to improve traffic safety method, has not yet seen the relevant reports.

[0003] Since the second half of the 19th century, the safe operation of railways has been determined by electromagnetic induction devices such as track circuits and track transponders to determine the position of the train. All positioning devices that use electromag...
