Abstract

In recent years, technological advancement in the railway sector and speeding up of logistics transportation have been achieved. The newly constructed high-speed railway and the newly constructed or improved general railway are being applied at the maximum speed of 200 km / h or more, It is classified as high-speed railway. According to the national railway network construction plan (2011 ~ 2020, the second), domestic railways are promoting the speeding up of many railway pioneers. Therefore, to secure safety facilities for high-speed operation, a tunnel alarm control box (TACS), an optical intrusion detector (OID), a rail status control panel (RSCP), a dragging detector, a safety switch (SS), a meteorological detector , Earthquake Alert System (EAS), Maintenance Crew Cross Railroad Device (MCCRD) and Train Approach Indicator (TAI). In recent years, there has been an ongoing accident involving train operators, For this purpose, many functions must be secured to secure the safety of the operator. In this paper, we review the additional functions of the tunnel alarm system for operator safety in the tunnel section. It is necessary to secure the function to protect the dangerous situation from the accidental entry of the tunnel alarm device by the operator's mistake. We investigated the monitoring and warning methods for unauthorized persons, In addition, due to the increase in the speed of the railway, an increase in the destructive power caused by collision with animals in the tunnel can lead to derailment of the train. As a safety function to prepare for dangerous situations, The study was conducted. Further, the high speed of the railway can cause derailment of train due to collision with animals in the tunnel. In order to prevent train derailment accident, we monitored the entrance of the animal to the railway tunnel and studied ways to prevent it.
