The present invention relates to a tunnel alarm device. More particularly, a tunnel alarm system detects the speed of a train when the train enters a certain area in order to protect an inspector in a tunnel, calculates the time when the train arrives at a tunnel entrance, and provides alarm by securing an evacuation time (30 seconds) so that the inspector in the tunnel can evacuate. In addition, the tunnel alarm system has a function to alert the inspector when the inspector enters the tunnel without approval and handling of a handling button (inspector present).

    본 발명은 터널 경보 장치에 관한 것으로서, 보다 상세하게는 터널경보장치 시스템은 터널내 점검자를 보호하기 위해 열차가 일정구역에 진입시 열차의 속도를 검지하여 열차가 터널 입구에 도착하는 시간을 계산하여 터널내 점검자가 대피할 수 있도록 대피시간(30초)을 확보하여 경보하는 시스템이며, 또한 터널내 점검자가 승인 및 취급버튼(점검자 있음)의 취급 없이 터널내 진입시 경보하는 기능을 갖는 터널경보장치 시스템이다.
