가선구간 신호기 LED모듈 설계에 관한 연구

Abstract

The signaling device is installed on the left side of the track to present the conditions of the train to the engineer. Due to the nature of the installation, it is necessary to install it in the section of the cable line. Therefore, when the signaling device fails, the operator must perform the maintenance work up to the top of the signaling device In accordance with the railway signaling system design guidelines, the car lines and signaling devices should be installed at a sufficient distance from each other. However, there is a case where the induction voltage is induced from the high-voltage electric wire (25,000V) to the signal device depending on the installation position, the weather environment, and the grounding condition. In order to prevent safety accidents such as worker's electric shock, We will do more efficient maintenance work by improving the operation method of LED module which is the main cause of failure. In this study, we analyzed the history of the railway signaling equipment in Korea, the problem of the maintenance of the signaling device and the signaling device of the signaling line, and the cause of the main failure situation of the signaling device, In this paper, we propose the direction of improvement of the signaling device so as to ensure the safety of the operator with quick failure recovery.
