Method and system for overcoming poor branches of track circuit by using axle counting equipment

Abstract

The invention discloses a method and system for overcoming poor branches of a track circuit by using axle counting equipment. An axle counting sensor is respectively arranged on a main circuit of a straight rail and a branch rail at a turnout; output signals of the two axle counting sensors respectively act together with an output signal of a reverse table relay; when the reverse table relay and the axle counting sensor output high levels simultaneously, the axle counting sensor counts; and when the axle counting sensor or the axle counting sensor outputs a low level, the axle counting sensor does not count. According to the invention, the vehicle at the turnout can be counted via two axle counting sensors so that the cost and the complexity of an axle counting system are greatly reduced.

Description

[0001] technical field [0002] The invention discloses a method and system for solving problems in rail application, in particular a method and system for solving poor branching of track circuits by using axle counting equipment. Background technique [0003] Rail transport occupies a pivotal position in people's daily life, and occupies a large proportion in land transport. Since rail transportation belongs to rail transportation, due to its special operation mode, the requirements for its operating environment are also very high. What is especially important is that at the same time, only one train can exist on the same section of the rail route. Currently, the most widely used means for detecting the presence of trains on rails is track circuits. The track circuit is a circuit composed of the rail of a section of rail line as a conductor, which is used to automatically and continuously detect whether this section of line is occupied by rolling stock, and is also...

Problems solved by technology

However, a common problem in the current track circuit is that it is prone to poor shunting at the turnout.

Poor track circuit shunting means that the track circuit track surface is affected by bad conductors and the track relay that controls the track section cannot fall normally when the train or train occupies the track, resulting in signal interlock failure.

This may lead to receiving and dispatching trains or shunting trains to the section occupied by cars, and the serious consequence is a car crash

In the prior art, the method used to solve the problem of shunting is mainly to use the track circuit to cooperate with the axle counting system. Please refer to the attached figure 1 , the axle counting system installed at the turnout usually needs to install an axle counting sensor on the straight rails on the front and rear sides of the turnout, and install an axle counting sensor on the branch track at the turnout. Such an axle counting system needs to cooperate with The use of three axle counting sensors, whether it is the difficulty of system design or the complexity of installation
