Hereinafter, the process will be described in detail.

First, the train system control step S100 will be described.

When the train 1 starts to operate, the train control unit 150 detects train operation information such as train position, train speed, and the like, as shown in FIG. 12, and at least one terminal system through the mobile communication network 2. The train information transmission step (S110) for transmitting to the train system and the situation room system 300 of the other trains through the mobile communication network (2) and transmits the emergency situation information such as a train accident and the train operation information (2). do.

That is, the GPS system 111 and the automatic navigation device 112 of the train position detecting unit 110 and the speed detecting unit 180 detect the train position and the speed through the train mobile communication unit 164 and the corresponding terminal system 200. ) And the situation room system 300, and detects whether a collision, collision, or derailment through the emergency situation detection unit 120, or a signal indicating that an emergency situation has occurred through the train operation switch unit 140 Detects whether or not is input and transmits emergency information indicating this to other trains and the situation room system 300.

The corresponding terminal system refers to a terminal system carried by a track worker in a track work section located on a train 1 traveling path.

Whether or not the track work section located on the progress path is determined by the track work information transmitted from the terminal system 200 or the track work information input to the situation room system 300.

Techniques for detecting train position and speed using the GPS receiver 111, or a method for detecting train speed through a speed detector (not shown) pre-installed in a train, are well known, and thus detailed description thereof will be omitted. Since the collision detection unit 121 or the derailment detection unit 122 of the emergency situation detection unit 120 detects whether the train collides, collides, or derails, the detailed description thereof is omitted.

The speed detected by the speed detector 180 is given priority among the train speeds detected by the train position detector 110 and the speed detector 180, and the speed detected by the GPS receiver 111 is the speed detector 180. It is used when the operation of the speed detector which constitutes) is not normal.

After performing the train information transmitting step (S110), the train control unit 150 performs the train information receiving step (S120) to transmit the track work information transmitted from one or more terminal systems 200 and other train systems Receive emergency information.

Thereafter, the train control unit 150 continuously calculates the distance between the train and the track work position from the train position and the track work position detected by performing the train information transmission step S110 and the train information receiving step S120. When it is determined that the track work alarm signal generation position indicating that the train is close to the track work position is reached, a work position approach alarm step (S130) of generating the track work alarm signal is performed.

That is, the distance between the train and the track work position from the information on the train position and speed detected by performing the train information transmission step (S110) and the track work position detected by performing the train information receiving step (S120) and It calculates the arrival time, and determines whether the distance and the arrival time is the predetermined position of the line work alarm signal generation, and if it is determined that the line work alarm signal is generated, an alarm signal (voice guidance, warning sound, or screen) indicating this. Display, etc.) is generated through the train display alarm unit 170.
