Railway and subway cars are facilities used by a large number of passengers and have the characteristic of moving at a high speed, which can lead to a large personnel accident when a fire occurs.

Conventionally, passengers passively detect and evacuate passengers or automatically detect a fire to prevent passengers from being injured by flame, heat, smoke or toxic gas in the event of a fire in a train vehicle, I was evacuated.

In addition, as a system for suppressing a fire, a fire extinguisher which is disposed at a predetermined position inside the vehicle and can suppress a small fire by a passenger manually, a facility capable of manually opening the door of the vehicle as a means of evacuation, Facilities that can make calls (interphone _, etc. are provided.

Also, since a large number of passengers are aboard the railway and subway cars, the space inside the vehicle is narrow, so that the movement of the passengers for suppressing them in the event of a fire is not free, and it becomes difficult to operate the fire extinguisher or manually open the door of the vehicle There is a problem in that it can occur.

In order to solve such a problem, the prior art Patent Registration No. 10-0637846 discloses a train automatic fire suppression device.

The train automatic fire suppression apparatus includes a fire detection unit provided in each vehicle of a train to detect a fire occurrence and to be assigned a fire detection identification number matching the vehicle number of each vehicle.

A nozzle unit provided in each of the vehicles for spraying the extinguishing medium when it is determined by the control unit that a fire has occurred;

A valve for selectively opening and closing the housing and the nozzle unit, an actuator for driving the valve by the control unit, and a control unit for controlling the filling pressure of the extinguishing medium in the housing, A fire extinguishing medium discharging part including a filling pressure sensor part for detecting a fire sensing ID number and matching the fire sensing identification number; And

A fire detection unit for receiving a signal from the fire detection unit to determine a fire detection identification number and driving the actuator of the fire extinguishing medium discharge unit to which the fire detection identification number is assigned to discharge the fire extinguishing medium, A controller for determining that the extinguishing medium in the housing is exhausted when the pressure value is lower than a predetermined pressure; .

However, the automatic fire suppression device of the above-mentioned train can transmit an occurrence of an emergency situation to a cab or history room through a communication terminal such as an interphone installed in each train car while performing an automatic or manual fire extinguishing operation in case of an emergency such as a fire , It is not suitable to apply to unmanned railway vehicles where unmanned operation without an engineer should be controlled by the general command room in case of an emergency situation.

As such, recently, a fire suppression device is mounted on a railway vehicle to secure passenger safety by suppressing the fire in the event of a fire, and to minimize vehicle loss.

However, the current railway vehicles are increasingly used for unmanned driving systems, and the commuter type electric trains have been changed from the existing large-sized vehicles to the unmanned operation mode, and are being controlled at the general command room.

Therefore, the vehicle of the unmanned operation system is less stable than the vehicle of the incentive driving system having the engine, which causes a problem of stability, which is also a problem in the occurrence of fire.
