Description
The present invention relates to a wheel detecting system and a control method thereof, and more particularly, to a wheel detecting system and a control method thereof, which can minimize installation, operation cost and failure rate by minimizing the on-site facilities, thereby greatly improving the quality and reliability of the system. It satisfies the needs (needs) so that it can give a good image.
As is known, a track circuit, a loop line, an excel counter, and the like are widely used as a method of confirming the presence of a train (vehicle) traveling on a track.
In the track circuit system, an electric circuit is formed on a rail to apply a current, and the presence of a train (vehicle) is detected by electrical shorting of both rails by an axle.
Also, in the loop line method, a cable is installed inside both rails, a frequency is passed, and a change in inductance is detected according to the physical characteristics of a train to determine the presence or absence of a train (vehicle).
On the other hand, the wheel sensor (accelerator counter) has a function of detecting the presence of the wheel by a special sensor attached to the rail. The method of the wheel detector is an electromagnet method for detecting the approach of the metal body and a magnetic field method for detecting the interruption of the magnetic field.
As described above, the technique of detecting the presence or absence of a train is used as a technique for preventing a collision or collision between trains running on a railway line, and also provides information necessary for understanding the position and flow of a train in a control room And is used as an important device for performing an operation.
On the other hand, when the train travels the track, a transmission coil (in the transmission head) is disposed on one side of the rail and a reception coil (in the reception head) is disposed on the other side of the rail on one side of the rail. Normally, And generates a current by magnetic induction in the closed loop at the receiving coil on the opposite side of the rail. In this structure, when the wheels of the train are placed between the transmission head and the reception head, the magnetic field is cut off by the wheels as shown in FIG. The magnetic induction current becomes small due to the reduction of the magnetic field in the receiving coil. Using this state, the sub rack (signal comparison detecting section) judges that there is a " wheel exists ". When induction current normally occurs in the receiving coil, it is judged as "no wheel" in the sub rack.
As described above, it is the basis of train operation to accurately ascertain the presence or absence of a train on a specific trajectory.
2A schematically shows the principle of the most used closed-loop type orbit circuit.
When a train occupies a track, the track circuit is short-circuited, and the current flowing in the track relay is disconnected. However, its use is restricted in situations where electrical separation of the track is difficult, such as a line switch, or where insulation between tracks, such as steel bridges, can not be adequately maintained.
An axle counter that detects the axle of a passing train is used as an alternative. If the number of axles counted from both sides of the axle detecting device is set at the entrance and exit of a specific line section, there is no more train within the line section It is a principle to judge it as not.
The axle counter does not need to electrically isolate the trajectory, and it works only by fixing the detecting device to the track and it is very easy to install.
And Fig. 2B shows a general installation configuration of the track vehicle position detecting system of the axle counter principle.
The detector is attached to the track and connected to the detector which is housed in the structure installed on the track side, and the signal is processed and sent to the controller installed in the nearby reverse signal equipment room to operate the track relay.
In order to use the actual axle counter, it is necessary to build such a complicated multi-stage system, so that installation and maintenance costs are increased.
The following prior art documents have been developed in order to solve the problems of the prior art, but the following problems have not yet been solved.
