Description

FIELD OF THE INVENTION [0001] The present invention relates to a position detection device for a magnetic levitation train using a magnetic bar and an RFID tag,

[0001] The present invention relates to a magnetic locus detection apparatus for a magnetic levitation train using a magnetic bar and an RFID tag, and more particularly, to a magnetic locator having N poles and S poles along a line and counting a magnetic bar through a magnetic reader RFID tag which can detect the relative position, detect the traveling direction according to the detection waveform comparison, and can detect the absolute coordinates at every predetermined interval, can be installed separately to provide a magnetic bar having a high precision and low installation cost, And more particularly to a train position detecting apparatus for a floating train.

As is well known, in a general railway system, the position and speed detection of a high-speed floating train (steel wheel type) can be detected by using a track circuit installed on the ground and a tachometer or otometer installed on the train.

That is, by using the tachometer or otometer installed on the iron wheel of the train, the moving distance and speed of the train are counted by counting the number of voltage pulses outputted at the time of wheel rotation, and by using the track circuit installed on the ground, And the position of the train is possible by the short of the iron wheel.

Thus, the position and speed information of the trains obtained by using the trajectory circuit and tachometer or otometer is utilized as key information for train control such as train control, route locking, and interval adjustment of trains.

However, in the case of a magnetic levitation train in which the rotation of the wheel does not come into contact with the track, it is impossible to check the position and speed of the train based on the existing tachometer and track circuit. .

1A and 1B are views showing a conventional contactless position sensing device for a magnetic levitation train.

Referring to this, a conventional non-contact position sensing device for a magnetic levitation train includes an on-vehicle equipment of a magnetic levitation train 2 including a vehicle signal generator 4 and a vehicle antenna 6; A cross loop coil 8, and a terrestrial detection signal information processing device 10. [

First, when a magnetic levitation train 2 equipped with an on-board facility passes a high frequency signal from a vehicle signal generator 4 of a magnetically levitated train 2 through a vehicle antenna 6 on an orbit When the induced voltage is induced in the loop coil 8, the grounded detection signal information processing device 10 receives and processes the induced voltage signal to determine the exact position and speed of the train in the orbit section provided with the crossed loop coil on the ground .

The voltage induced in the crossing loop coil 8 by the vehicle antenna 6 has a characteristic proportional to the area size of the crossing loop coil 8 that meets the vehicle antenna 6 and the cross- When the vehicle antenna is located at a large point, the voltage induced in the cross loop coil 8 becomes the maximum, and when the vehicle antenna is located at the point where the area of the cross loop coil is the smallest, the voltage induced in the cross loop coil 8 Is minimized.

The ground detection signal information processing apparatus 10 processes the high frequency voltage signal induced by the passage of the vehicle antenna 6 over the crossing loop coil 8 to grasp the position. Therefore, since the relationship between the vehicle antenna 6 and the crossed loop coil 8 affects the quality of the induced high frequency voltage signal, the size of the vehicle antenna 6 must be smaller than the alternating distance of the crossed loop coil 8 do.

At this time, the vehicle antenna induces the high frequency voltage only at the alternating interval of the cross loop coils, and the alternating interval corresponds to the resolution of the position information.

Therefore, when the vehicle antenna 6 mounted on the vehicle passes through the upper portion of the cross loop coil 8, a voltage similar to that of the cross loop coil 8 shown in FIG. 1B is detected, The wavelength of the + component remains. When the digital processing is performed, the pulse waveform is converted to count the number of pulses so that the actual travel distance can be calculated.

The calculation of mileage will ultimately be used to determine the current position of the vehicle to sense its current position and speed.

However, the conventional non-contact position sensing device for a magnetic levitation train has a disadvantage in that the installation cost is very large because the cross-loop coil 8 must be buried along the line. In addition, there is a problem that a method of inducing the intersecting loop coil 8 through the vehicle antenna 6 causes an error.

In addition, the conventional non-contact position sensing apparatus for a magnetic levitation train is a relative position detecting apparatus through a pulse wave counter. When a small error is accumulated, an error occurs in the position of a magnetic levitation train requiring high precision, There is a risk that there is a risk of.

Further, the conventional non-contact position sensing device for a magnetic levitation train described above is a relative position detecting device through a pulse wave counter. When the magnetic levitation train is reversed, there is a problem that it is difficult to detect the running direction in a short distance travel.
