Description

Tilting Train Vehicle Signal Angle Receiving Angle Corrector {The Device of CAB Signaling Correction Antenna for Tilting Train}

The present invention relates to a tilting train onboard signal antenna receiving angle correction device, and more particularly, to a tilting train onboard vehicle to ensure stable signal reception through the horizontal acquisition between the ATP onboard antenna and the ATP ground antenna regardless of the tilting operation. The present invention relates to a signal antenna reception angle correction device.

A tilting train is a train that can operate a curved section at high speed by tilting the body toward the center of the curve to offset the centrifugal force of the train. The tilting train developed in Korea is designed to pass through the curved section at high speed by tilting up to 8 degrees toward the center of the curve according to the curve size when the curved section runs.

The ATP ground antenna is installed before the occlusion of the ground and is a safety facility to secure safety from the speeding of the train by receiving the authorization of movement of the train according to the signal status and the geographic information of the operating section.

Automatic train protection (ATP) car antenna receives information for safe operation of trains, such as the location of the preceding train and the speed limit of the train, through the ATP ground antennas installed in certain areas of the ground. The maximum allowable angle of tilting direction of ATP vehicle antenna for receiving information of ATP ground equipment installed between domestic steel tools is allowed up to 3 degrees including installation error during construction.

As described above, the ATP device uses information transmission between the ATP ground antenna and the ATP onboard antenna to receive information from the ground to the vehicle. As soon as a train with ATP onboard antenna passes through the ATP ground antenna, a telepowering signal is transmitted from the ATP onboard antenna to activate the ATP ground antenna, and the ATP ground antenna activated by the telepowering signal is used for train operation. The information is sent to the ATP onboard antenna.

If a train operating at about 200km / h passes the section where the ATP ground antenna is installed, it fails to receive information because the ATP car antenna and ATP ground antenna are not horizontally secured from the ground by the ATP car antenna. The braking is configured to be performed by the safe side operation.

As well as the tilting train, the ATP vehicle antenna installed in the general train is installed at the lower part of the front head vehicle of the train as shown in FIG. However, as shown in FIG. 2, in the case of the tilting train, the train inclines to a maximum of 8 degrees, and thus the angle between the ATP vehicle antenna and the ATP ground antenna is out of 3 degrees for the normal signal transmission of the ATP vehicle antenna and the ATP ground antenna. Stable information transmission is not guaranteed.

Therefore, the information transmission failure of the ATP vehicle antenna and the ATP ground antenna due to the tilting operation when the tilting train passes the high speed of the curved portion has a problem that causes the train operation efficiency to be greatly reduced.

The present invention has been made to solve the above problems, the tilting train vehicle signal correction angle correction to ensure stable signal reception through the horizontal acquisition between the ATP vehicle antenna and the ATP ground antenna regardless of the tilting operation The object is to provide a device.

Reverse tilting control motor driven by the reverse, the reverse for transmitting the driving power by connecting the first pulley mounted on the shaft of the reverse tilting control motor and the second pulley connected to the end of the fixed support located in the lower center of the controller fixing plate It is fixed to the tilting driving belt and one surface of the second pulley so that it is horizontal with the ATP ground antenna. That is characterized in that comprising an ATP-board antenna angle that varies as the second pulley is driven by a drive motor of the tilting control station.

In addition, when the tilt angle information is not input to the reverse tilting controller from the vehicle tilting control device, the reverse tilting signal is arithmetic processing in the reverse tilting controller received a signal output from the inertial sensor attached to the train And output to the reverse tilting control motor.

In addition, the reverse tilting controller is characterized in that to maintain the angle between the ATP vehicle antenna and the ATP ground antenna within -3 degrees to +3 degrees.

According to the tilt angle of the on-vehicle signal antenna receiving angle correction device according to the present invention, stable information transmission is possible by maintaining the horizontal between the ATP on-vehicle antenna and the ATP ground antenna, which is essential for the safe train protection of the tilting train operating the curved section.

The present invention provides a tilting train in order to prevent an error in information transmission due to exceeding a maximum allowable angle of 3 degrees, which is the maximum allowable angle of information transmission between the ATP vehicle antenna 90 and the ATP ground antenna 60 according to the tilting operation during the curve section of the tilting train. By back compensating the angle of the ATP onboard antenna 90 according to the tilting angle, the ATP onboard antenna 90 maintains the angle correction means 100 that is horizontal with the ATP ground antenna 60 regardless of the tilting motion of the tilting train.
