Description

  The present invention relates to a fire fighting activity support system that enables a safe entry into a fire room at a fire site.

Conventionally, as a system to support the activities of firefighters, the firefighters are equipped with an acceleration sensor, the attitude data of the firefighters are transmitted wirelessly to a predetermined remote location, and the firefighter's work abnormality is confirmed at that remote location. What is to be confirmed is known (for example, see Patent Document 1).
By the way, fire fighting activities at the time of a fire in a building are mainly carried out through an approach route extending from ancillary rooms, corridors, and living rooms. Generally, there are not only fire extinguishing but also exploration and rescue of evacuees. It plays an important role as well as and sprinklers. Especially in buildings such as skyscrapers and hospitals, the importance of firefighting is greatly increased because the speed of fire fighting activities greatly affects the rescue of residents. As a factor that determines the speed of fire fighting activities, there is information grasping of the fire room.

However, conventional fire fighting activities have the following problems.
In other words, a general room in a building is surrounded by doors and walls, making it difficult to see the state of the room. There is a problem that it is difficult to know whether it is difficult to enter in fire fighting. In particular, a room that is strong against a fire external force composed of fire prevention equipment such as a fire prevention wall or a fire door of an iron door is in a state in which it is difficult to capture accurate fire information inside.
For this reason, if the door of the fire room close to the location of the fire was opened, the hot thermal air flowed out of the room as soon as it was opened, and the fire brigade could be exposed. Therefore, the fire brigade gathers information on the location of the fire in the fire room and the location of the high heat generation prior to entering the fire room, and after carefully examining it, it takes time to do so. There was a problem that the speed of fire fighting activities declined.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a fire fighting activity support system capable of grasping temperature information on the fire side and performing fire fighting activities safely and quickly.

  In order to achieve the above object, in the fire fighting activity support system according to the present invention, the fire fighting activity support for supporting the approach of a fire brigade from a non-fire room that becomes an evacuation route in the event of a fire to a fire room having a plurality of fire-proof doors The system includes a supply air pressurizing means provided in a non-fire room, a smoke exhaust means provided in the fire room, a smoke detection means for detecting smoke generated in the fire room, and a plurality of fireproof doors. Provided with a temperature display means for displaying temperature information of the fireproof door on the non-fire room side door surface, and when the smoke detection means detects smoke in the fire room, the supply air pressurization means detects the non-fire room. The pressurized air supply is performed, and the smoke is exhausted by the smoke exhausting means.

In the present invention, when a fire occurs in the fire chamber and smoke is detected by the smoke detection means, pressurized air supply to the non-fire chamber is performed by the supply air pressurization means based on this detection information, and the smoke discharge means As a result, smoke is discharged from the fire chamber, thereby forming a forced air flow from the non-fire chamber toward the fire chamber.
And since the temperature display means is each provided in the non-fire side door surface of the some fireproof door of a fire room, the fire brigade can confirm the temperature information of each fireproof door visually. Here, the temperature displayed by the temperature display means is the temperature of the fireproof door, and indicates the ambient temperature of the fireproof door of the fire room. Therefore, visually check the temperature display means of each fireproof door from the non-fire room side, select a fireproof door with a low temperature and enter the fire room, so that it enters a position away from the fire occurrence place in the fire room Can secure a safe fire-fighting route. At this time, as described above, since the air is pressurized from the non-fire room to the fire room by forced air supply, even if the fire-proof door of the fire room is opened from the non-fire room side due to fire fighting activities, Smoke does not flow from the room to the non-fire room.

  In addition, since only the work for checking the temperature display means of the fireproof door is required, it is possible to reduce the time taken to consider the route when entering the fire room, and the fire brigade can quickly enter. It becomes possible to promote.

  According to the fire fighting activity support system of the present invention, the temperature information on the fire room side is visually confirmed by the temperature display means of the fireproof door, thereby opening the appropriate fireproof door having a low temperature and entering the fire room. It is possible to suggest the optimal route to the fire brigade, and by forming an air flow based on the air supply pressurizing means and the smoke exhausting means, smoke can be sent to the non-fire room side even when the fireproof door is opened. Spills can be suppressed, which enables safe and quick fire fighting.
