DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fire monitoring system for 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, the sprinkler head or foam head within the area covered by the fire detector operates. The fire is automatically extinguished.

[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 this vehicle, only a small amount of smoke and a small change in heat occur, so it is not possible to detect this state early with the external fire monitoring in the conventional fire monitoring system. Have difficulty. 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.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to detect a fire that has occurred inside and outside a vehicle at an early stage and to know which vehicle has a fire.

[0007] The present invention provides: A: a portable fire detector installed in a vehicle in a parking lot, an inside air sampling pipe for communicating the fire detector with the interior of the vehicle, the fire detector and the vehicle. And B: a parking address of each parking section of the parking lot, and a vehicle provided with the parking section, which comprises: an outside air sampling pipe that communicates with the outside of the parking lot. A portable wireless fire detector having a self-address, an inside air sampling pipe for communicating the fire detector with the interior of the vehicle, and an outside air for communicating the fire detector with the exterior of the vehicle. A system for monitoring a vehicle fire in a parking lot, comprising a sampling pipe and a fire receiving unit in which the parking address and the self address are stored. A.

[0008]

When a fire occurs in the parking area, the smoke in the vehicle compartment is forcibly sucked through the inside air sampling pipe and comes into contact with the wireless fire detector. Also, the smoke outside the vehicle is forcibly sucked through the outside air sampling pipe and comes into contact with the sensor. Then, even if the sensor outputs, the fire signal and the self address are wirelessly transmitted to the 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 parking address and the corresponding self address in M22 are deleted (D2).

The embodiment of the present invention is not limited to the above. For example, as shown in FIGS. 5 and 6, the distal end portion 105a of the cylindrical inside air sampling tube 105 may be flattened. By doing so, the gap between the glass window 63 and the window frame 65 generated when the inside air sampling tube 105 is sandwiched can be minimized. Further, the fire detector is not limited to the wireless smoke detector, but may be, for example, a wireless heat detector.

Further, instead of sandwiching the inside air sampling tube between the glass window and the window frame, the inside air sampling tube may be inserted into a drawer hole used for installing an antenna or arranging electric wires, or may be held directly by being sandwiched between doors. In the above embodiment, the outside air sampling tube is connected to the detection box via the inside air sampling tube. However, the same effect as described above can be obtained even if the inside air sampling tube and the outside air sampling tube are connected to the detection tubes independently. . Furthermore, a fire extinguishing device, for example, a CO ₂ gas cylinder, may be connected to the inside air sampling pipe, and a fire extinguishing gas may be blown out into the interior of the vehicle through the inside air sampling pipe to extinguish the fire when a fire is detected. The present invention can be used not only in the mechanical parking lot described above but also in a general self-propelled parking lot.

[0021]

As described above, the present invention is configured as described above. When a fire occurs inside and outside a vehicle placed in a parking lot and smoke is generated, the smoke is forcibly sucked into the sampling pipe and the fire is generated. Touch the detector. Therefore, the fire can be detected earlier and more reliably than when the smoke naturally approaches the fire detector. Further, when the wireless fire detector detects a fire, the fire signal and the self-address are wirelessly transmitted from the detector to the fire receiving unit, so that the fire can be detected at the initial stage of fire occurrence. It is possible to know which parking section of the vehicle has a fire. Therefore, the fire extinguishing operation can be performed earlier and more accurately than in the conventional example.
