A system for solving poor branching of track circuit sections in stations based on ranging sensors

Abstract

The invention discloses a system for solving poor branching of a track circuit section in a station based on a distance measuring sensor, which includes at least two distance measuring sensors for real-time detection and output of the distance value from a sleeper in the track circuit section to the bottom of the train; control The board is used to receive the distance value output by the at least two ranging sensors, judge whether the train occupies the track circuit section according to the distance value, and if so, the control board outputs a control signal to the electric control switch to make the electric control switch act Turn on the branch line, if not, the control board outputs a control signal to the electric control switch to make the electric control switch act to disconnect the branch line; the branch line is located outside the left and right ends of the track circuit section, and the two ends behind the electric control switch are connected in series The parts are respectively connected to the steel rails in the track circuit section, and are used for conducting or disconnecting the two steel rails when the electric control switch is actuated. The invention adopts a technical scheme different from the existing mainstream scheme, has high reliability and safety, low cost, and is simple and easy to implement.

Description

[0001] This application claims the Chinese priority right of the patent with application number 201410223003.1 submitted on May 23, 2014. technical field [0002] The invention relates to the field of detection of bad branching of railway track circuits, in particular to a system for solving bad branching of track circuit sections in stations based on distance measuring sensors. Background technique [0003] Signals are the "eyes" of railway trains, and an important means to ensure traffic safety, realize centralized and unified command, and improve transportation efficiency. With the development of the railway, signal blocking has also developed from semi-automatic blocking to fully automatic blocking, and the driving intervals or sections have been shortened. At the same time, after 6 speed increases, only one train can run on each interval or section. Therefore , the safety of driving is even more prominent. Judging whether a section or section is occupied by a car is cu...

Problems solved by technology

[0006] The present invention assists the existing track circuit to complete the track occupancy judgment. It aims at the problem of poor track branching and utilizes the principle that the distance from the bottom of the train to the sleeper box is limited when the train occupies the track circuit section in the station. The distance from the sleeper box to the bottom of the train in the track circuit section is monitored in real time, and the track occupancy situation is obtained through the processing of the control panel, and then the rail line is connected by the method of controlling the branch line through the electric control switch according to the occupancy situation, so as to realize effective branching. Achieve the effect similar to the formation of train axles
