KR950008263A - Track circuit fault detection device - Google Patents

Abstract

The present invention relates to a failure detection device of the track circuit device of the signal equipment used in railways and subways, in the current technology, when the track circuit device that is the device for detecting the presence or absence of the train occupied or moved on the track In the present invention, it takes a long time to detect a faulty part. According to the present invention, the transmitter and the receiver 202 input and receive levels are respectively received and compared with the reference value for each line section. By displaying the level status, it is possible to easily grasp the current train operation status and classify the transmitting side, the receiving side, or the track (rail) side at the time of fixation, and display the cause of failure on the attached monitor. In addition, it is an invention that enables safe train operation by shortening the working time for troubleshooting.
