It emits a laser light having a straightness (S33). The light emitted from the laser pointer 270 serves to guide the entrance and exit direction when it is difficult to determine the entrance and exit direction due to the smoke generated during the fire.

If it is determined that the fire did not occur in the process of detecting whether the fire occurs (S31), it is determined whether the earthquake is generated by the earthquake detector 250 (S34).

When it is determined that a fire or earthquake has occurred in the above process, the alarm device 230 operates to transmit a disaster situation to the train user (S35).

 When it is determined that the fire and earthquake occurs, the alarm device 230 operates to check whether the screen door in the landing is currently open (S36), and when the screen door is closed, transmitting an open signal to each screen door. The process follows (S37).

In the process of detecting whether the earthquake is generated (S34), if it is determined that the earthquake has not occurred, the central control unit 130 checks whether the operation of each screen door and various safety devices (S38), the screen in the process If it is determined that there is an error in the operation of the door is made, including the process of transmitting the error history to the system management center 300 (S39).
