Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle fire monitoring system for a parking lot.

[0002]

2. Description of the Related Art In recent years, a three-dimensional mechanical parking lot has been constructed from the viewpoint of effective use of land. In this parking lot, vehicles are automatically taken in and out of a parking section of a parking stage arranged in multiple stages by using a transportation means such as an elevator or a traveling carriage, but with a high density without people. It can be parked, so it is attracting attention.

This parking lot is provided with a fire extinguishing system, but in view of the fact that there is no room for people to enter the parking lot, this system is all automatic. That is,
In this system, fire detectors are installed on the ceiling of each parking stage at appropriate intervals, and when the detector detects a fire, the sprinkler head or foam head within the range covered by the fire detector operates. The fire is extinguished automatically.

[0004]

A fire in a mechanical parking lot usually occurs inside a vehicle, and most of them are caused by mischief of cigarette butts. However, in the initial state of the fire that occurred inside the vehicle, only a small amount of smoke and a small amount of heat change occur, so it is difficult to detect this state early by external fire monitoring in the conventional fire extinguishing system. Is. Therefore, since the discovery of the fire is delayed, the fire may spread and the fire may spread to other vehicles, or the control device such as the elevator or the traveling vehicle may break down, and the parking lot may malfunction.

Further, in a conventional parking lot, it is difficult to know exactly which vehicle in which parking space has a fire, so it is not possible to quickly extinguish the fire.

In view of the above circumstances, an object of the present invention is to detect a fire that has occurred in a vehicle at an early stage and to know in which vehicle the fire has occurred.

According to the present invention, a parking address of each parking portion of a parking lot, a wireless fire detector provided in the vehicle of the parking portion and having a self address, the parking address and the self address are stored. The in-vehicle fire monitoring system for a parking lot, which comprises:

[0008]

When a fire occurs in a parked vehicle, a wireless fire detector installed in the vehicle is activated to wirelessly send a fire signal and a self-address to a fire receiver. Since the parking address of the parking section and the self-address of the fire detector are entered in advance in this fire reception section as a comparison table, which parking section of the vehicle has the fire caused by the fire signal. Can know.
