Abstract

The present invention provides an entry warning apparatus and an emergency stop apparatus at a branch point, comprising a transmitting unit installed at one side of the branch point to transmit a message containing the contents of no entering in an emergency driving mode in which an onboard signal security device does not operate; a receiving unit installed at one side of a train to receive the message from the transmitting unit and notify an engineer of an audio-visual warning signal; and an emergency stop device for controlling the train to be stopped just before the branch point if the engineer, who is not aware of the audio-visual warning signal, enters the branch point without stopping the train even after the audio-visual warning signal is received from the receiving unit. Therefore, if the engineer enters a wrong path in the emergency driving mode, the entry warning apparatus notifies the engineer of wrong entry with a beep for wrong entry from the branch point, and if the train do not stop, the emergency stop apparatus connects to a brake system just before the train enters the branch point to automatically stop the train, thereby preventing train accidents such as train collision and trailable moving.

본 발명은 열차안전사고를 예방할 수 있는 경고장치와 비상정지장치에 관한 것으로, 구체적으로는 비상운전모드에서 기관사가 잘못된 진로로 진입하는 경우, 분기부로부터 기관사에게 오진입 경고음을 알려주고 열차가 정지하지 않을 경우 분기부 진입 직전에 제동장치와 연동하여 열차를 자동으로 정지시킴으로서 열차추돌 및 할출 등의 열차안전사고를 예방할 수 있는 분기부 진입 경고장치와 분기부 비상정지장치에 관한 것이다.The present invention relates to a warning device and an emergency stop device that can prevent a train safety accident, specifically, when the engineer enters the wrong course in the emergency operation mode, the driver tells the driver to enter the warning alarm from the branch and the train does not stop. If not, it relates to a branch entry warning device and branch emergency stop device that can prevent train safety accidents such as train collision and runaway by automatically stopping a train in conjunction with a braking device just before entering a branch.

철도 운전자가 열차를 자동운전 혹은 수동운전 모드로 운행하다가 측선, 차량기지 등에 신호설비가 없거나 고장 혹은 오작동으로 인하여 인접 역, 대피 역 혹은 차량기지로 이동하기 위해 육안운전을 하는 경우에 운전자는 비상운전모드로 전환하기 위해 관제사(사령원)와의 열차무선으로 승인을 받고 운전하고 있다.When a railroad driver operates a train in automatic driving or manual driving mode and performs visual operation to move to an adjacent station, evacuation station or vehicle base due to a failure or malfunction due to lack of signaling equipment at the sideline, vehicle base, etc. In order to switch to the mode, he is approved by a train radio with a controller (Commander) and is driving.

우선, 도 1(a)에 도시된 바와 같이, 분기부(10)에 진로개통신호기(20)가 설치되어 열차 운전자는 진로개통신호기(20)의 신호에 따라 운전한다. 이때 도 1(b)에 도시된 바와 같이, 운전자가 상기 진로개통신호기(20)의 정지신호를 인식하지 못하고 진입하면 열차는 내부에 구비된 차상신호보안장치(도시되지 않음)의 작동으로 자동으로 제어되어 정지하게 된다.First, as shown in FIG. 1 (a), the career path communication unit 20 is installed in the branch unit 10 so that the train driver operates according to the signal of the career path communication unit 20. At this time, as shown in Figure 1 (b), when the driver does not recognize the stop signal of the career dog communication unit 20 enters the train is automatically operated by the operation of the on-board signal security device (not shown) provided therein Controlled to stop.

그러나, 종래에는 상기 비상운전모드에서 지정된 제한속도 이하로 운전자가 전방을 주시하고 서행으로 운전을 하지만 상기 차상신호보안장치가 작동하지 않기 때문에 상기 분기부(10)에서 상기 진로개통신호기(20)를 인식하지 못하고 잘못된 진로로 진입하는 경우에도 자동정지기능이 작동 하지 않아 할출 또는 할출 후 정지열차(30)와 추돌사고 등의 안전사고가 발생할 문제점이 있다.However, in the prior art, although the driver looks forward at a speed lower than the specified speed limit in the emergency operation mode and operates in a slow direction, since the on-vehicle signal security device does not operate, the branch opening unit communication unit 20 is disconnected from the branch unit 10. In case of entering the wrong course without recognizing, there is a problem that a safety accident, such as a stop train 30 and a collision accident, occurs after a runaway or a runout because the automatic stop function does not work.

또한, 비상운전모드로 상기 진로개통신호기(20)의 정지신호를 인식하지 못하고 분기부(10)에 진입하면 진로 개통과 불일치하는 방향으로 열차를 진입시키는 인적오류로 인한 열차추돌 및 분기부 할출 등의 안전사고가 발생할 문제점이 있다.In addition, when entering the branch unit 10 without recognizing the stop signal of the career open communication unit 20 in the emergency operation mode, train collision and branch runout due to human error that enters the train in a direction inconsistent with the opening of the course. There is a problem that a safety accident occurs.
