Apparatus and method for controlling fire at railway vehicle

The present invention relates to fire monitoring of a railroad car, and more particularly, a fiber optic sensor of a wireless sensor network type is attached to a ceiling and a seat inside a vehicle, and the temperature is monitored in real time to quickly extinguish a fire and voice a fire. The present invention relates to a fire control apparatus and method for a railroad car that quickly and safely responds to a fire by processing an alarm and a guide broadcast of passengers.

Wireless Sensor Network (WSN) is a network that transmits the information sensed by the sensor to wireless communication. Unlike the existing network, the Wireless Sensor Network (WSN) is not a means of communication but the purpose of automated remote information collection. It is widely used in various application developments such as commercial and commercial use.

A fire suppression apparatus for a conventional railway vehicle will be described below.

Prevention of fire is important because fires in public transportation, such as subways and electric cars, can generate flames, smoke and toxic gases and lead to major accidents. In addition, when the fire of a passenger car is small, the interior space is narrow and the installed chemical fiber chair and the plastic floor interior material are burned, which can cause toxic gas to further increase the casualties. In addition, subways that run on underground tracks do not have separate evacuation spaces, so a faster and faster fire evolution is the safest way to minimize casualties.

The conventional method of extinguishing a subway electric car is a method of extinguishing by hand, and a manual fire extinguisher provided in an inside of a passenger car is operated by a passenger to directly extinguish a fire. Conventionally, there is no sprinkler or fire detection device that operates automatically inside a subway car, and a 3.3 kg manual powder fire extinguisher is provided on the side of a carriage and a door connecting passage. After extinguishing a fire extinguisher, the fire extinguisher is to be extinguished according to the operation of the fire extinguisher.

However, in the conventional fire fighting methods, when many passengers are in a narrow space inside the vehicle, the movement of the passengers is inconvenient. Therefore, a fire cannot be controlled by fire extinguishing using only a fire extinguisher.

In addition, when a fire breaks out in the subway, passengers are embarrassed, so the use of fire extinguishers and fire extinguishing methods through firefighting training can easily become obsolete, and a serious problem that causes human accidents due to failure to extinguish a fire is necessary. .

In addition, the gateway provides the sensing data and the fire occurrence signal to the passenger carriage system and the central control system using Ethernet or WLAN, and the gateway stores and provides the position information and the sensing data of the optical fiber sensor.

The fire detection suppression unit includes a fire determination unit that determines whether a fire occurs by determining the temperature from the sensing data, and the passenger car operating system stops the train when receiving the fire occurrence signal and provides an announcement of a fire alarm and evacuation of passengers. And controlling the doorway to evacuate the passengers.

The method of the present invention for achieving the above object, the first step of providing a sensing data that periodically senses the heat in the optical fiber sensor installed in the train, and by detecting the temperature when receiving the sensing data from the fire detection suppression unit The second step of extinguishing the fire by determining whether the fire has occurred and operating the sprinkler at the fire occurrence point, and providing a fire occurrence signal from the fire detection suppression unit to the passenger car operating system and the central control system and operating the passenger car. The system includes a third step of generating a fire alarm, stopping the train, controlling the doorway, and guiding the passengers to evacuate.

In addition, in the second step, the sensing data is detected by the fire detection suppression unit, and if the temperature is 60 degrees or more, it is determined as a fire. The sensing data includes temperature and position information of the optical fiber sensor, and the second step is the fire detection suppression unit. If it is determined that the fire is in the train display board in the train is characterized in that it provides a fire occurrence guidance and alarm.

The present invention pinpoints and responds to the location of fires occurring in subways and railcars, thereby increasing the safety of railcars and protecting passengers from fires that can cause large-scale human accidents.
