DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing system in a parking lot.

[0002]

2. Description of the Related Art In recent years, three-dimensional mechanical parking lots have been constructed from the viewpoint of effective use of land. In this parking lot, vehicles are automatically moved in and out of the parking section of the multi-stage parking stage using transport means such as elevators and traveling trolleys. It's getting attention because you can park.

[0003] Although a fire extinguishing system is provided in this parking lot, in view of the fact that there is no room for humans in the parking lot, this system is all automatic. That is,
In this system, a fire detector is installed at an appropriate interval on the ceiling of each parking stage, and when the fire detector detects a fire, a sprinkler head or a foam head within the area covered by the fire detector is activated. The fire is extinguished automatically.

[0004]

[0003] Fires in mechanical parking lots usually originate from inside the vehicle, most of which are caused by mismanagement of cigarette butts. However, in the initial state of a fire that occurred in the vehicle, only a small amount of smoke and a small change in heat are generated, so it is difficult to detect this state early with the external fire monitoring in the conventional fire extinguishing system. It is. As a result, the discovery of a fire is delayed, and the fire may spread and spread to other vehicles, or a control device such as an elevator or a traveling vehicle may break down and the function of the parking lot may be reduced.

In a conventional parking lot, it is difficult to know exactly which parking section of a vehicle has a fire. Further, in the conventional fire extinguishing system, the fire extinguishing agent is ejected toward the outer surface of the vehicle, so that the fire in the vehicle cannot be directly extinguished. Therefore, it is difficult to extinguish the fire at the initial fire stage.

[0006] In view of the above circumstances, it is an object of the present invention to detect a fire that has occurred in a vehicle at an early stage and to know which vehicle has a fire. Another purpose is
This is to enable direct fire extinguishing in the car.

According to the present invention, a parking address of each parking section of a parking lot, a wireless fire detector provided in a vehicle of the parking section and having a self address, and the parking address and the self address are stored. It is an object of the present invention to achieve the above object by an in-vehicle fire extinguishing system for a parking lot, comprising: a fire receiving unit to be provided; and a fire extinguishing device provided in the vehicle.

[0008]

When a fire occurs in a parked vehicle, a wireless fire detector installed in the vehicle operates to transmit a fire signal and a self address wirelessly to a fire receiving unit. In this fire receiving unit, since the parking address of the parking unit and the self address of the fire detector are input in advance as a comparison table, the fire signal indicates which vehicle in the parking unit caused the fire by the fire signal. You can know. The fire extinguisher in the vehicle is activated by the signal of the fire detector, and the fire extinguishing is started.
