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, 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 has occurred inside the vehicle, only a small amount of smoke and a small amount of heat change occur, so it is not possible to detect this state early in external fire monitoring in the conventional fire monitoring system. Have difficulty. 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, it is an object of the present invention to detect a fire that has occurred inside or outside a vehicle at an early stage and to know in which vehicle the fire has occurred.

The present invention is: 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. A vehicle fire monitoring system for a parking lot, which comprises an outside air sampling pipe for communicating with the outside of the vehicle, and B: a parking address of each parking portion of the parking lot and a vehicle provided in the parking portion. And a transportable wireless fire detector having a self-address, an inside air sampling pipe for communicating the fire detector with the inside of the vehicle, and an outside air for connecting the fire detector with the outside of the vehicle A vehicle fire monitoring system for a parking lot, which comprises 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 section, smoke in the vehicle compartment is forcibly sucked through the inside air sampling tube and comes into contact with the wireless fire detector. Further, smoke outside the vehicle is forcibly sucked through the outside air sampling tube and comes into contact with the sensor. Then, even if the detector outputs, the fire signal and the self-address are wirelessly transmitted to the 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.

The operation of this embodiment will be described. When the vehicle G arrives at the entrance of the mechanical parking lot 1, the driver receives the mounting plate 101 having the wireless smoke detector W _{1 and the} like from the manager. The mounting plate 1 is attached to the surface of the roof 100 of the vehicle G.
Fix 01. Open the glass window 63 and the window 63 and the window frame 6
The suction port 104 is inserted into the room R from between 5 and 5. Then, when the glass window 63 is raised in the A63 direction, the tube 105 is sandwiched between the glass window 63 and the window frame 65. In this state, when the vehicle G is automatically moved to the vacant parking part 2a via the elevator 8 and the traveling carriage 5, the outside air sampling pipe 201 causes the ceiling 20 of the parking part 2a to move.
Located near 3

As shown in FIG. 5, when there is an entry (S1),
The manager inputs the self-address of the wireless smoke detector W ₁ mounted using the bar code or the numeric keypad of the manager M, reads the self-address of the sensor W from the interface I / F 22, and reads the self-address of the RAM 22. It is stored in a predetermined position (S2). Then, after the management unit M of the parking lot system conveys the vehicle and receives the signal of the position of the vacant parking unit 2a, that is, the parking address (S4), the parking address is read from the interface I / F 22, and the RAM 22 is read. The self-address and the parking address are stored so as to be a comparison table (S5).

The sensor W operates according to a program stored in the ROM 11, and normally reads the output of the detection unit FS through the interface I / F 11 and compares the value with the fire discrimination standard. At this time, the valve 10
Since 3 is opened and the pump P is started, the air (inside air) A in the room R is forcedly detected through the pipe 105.
The air (outside air) B outside the room D is blown into the tube 2 as well.
It is forcedly blown into the detection box 102 via 01. When a fire occurs in the vehicle interior R of the parking portion 2a and smoke is emitted, the smoke is forcibly blown into the inside air sampling tube 105 and comes into contact with the smoke sensor W ₁ . When a fire occurs in the outdoor space D of the vehicle in the parking portion 2a and smoke is emitted, the smoke is forcibly blown into the outside air sampling tube 201 and comes into contact with the smoke sensor W ₁ .

[0016] Smoke detectors W ₁ in this manner is in contact with the smoke, the sensing device W ₁ is the output of the detection portion FS detects the fire exceeds the fire discrimination reference, interface I / F
The fire signal and the self-address are wirelessly transmitted from the transmission unit PG to the fire reception unit RE via 12. When the fire signal enters the receiver AT (F1), it reads the own address of the sensing device W ₁ via the interface I / F21, reads the parking address corresponding to the address from the RAM22 the control table (F2). After that, the display section DP and the alarm section AM are operated via the interfaces I / F23 and I / F24 (F4).

When confirming whether the fire that occurred is indoor R or outdoor D, the valve 1 of the inside air sampling pipe 105 is used.
03 is closed and the outside air B is sucked only from the outside air sampling tube 201. At this time, if the detector W ₁ does not output a fire signal, it can be seen that a fire has occurred in the room R. The valve 103 may be provided in the connecting pipe 200 instead of being provided in the pipe 105.

When the parked vehicle G exits, the driver moves the window glass 63 in the direction opposite to the arrow A63 to pull out the inside air sampling tube 105 and then removes the mounting plate 101 from the roof 100 to detect smoke. Mounting plate 1 with container W ₁ etc.
Pass 01 to the manager. In this way, when there is a departure (D1), the fire reception part RE receives the interface I / F22 from the management part M.
Read the parking address of the vehicle G carried out via the vehicle or the self-address of the smoke sensor W ₁ removed, and RA
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 tip portion 105a of the cylindrical inside air sampling tube 105 may be flattened. In this way, it is possible to minimize the gap between the glass window 63 and the window frame 65 that occurs when the inside air sampling tube 105 is held. Further, the fire detector is not limited to the wireless smoke detector, but may be a wireless heat detector, for example.

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 drawing hole used for installing an antenna or arranging an electric wire, or may be directly sandwiched between the doors and held. Further, although the outside air sampling tube is connected to the detection box via the inside air sampling tube in the above-described embodiment, the same effect as above can be obtained by connecting the inside air sampling tube and the outside air sampling tube to the detection tube independently. .. Further, a fire extinguishing device, for example, a CO ₂ gas cylinder may be connected to the inside air sampling pipe, and when a fire is detected, a fire extinguishing gas may be injected into the vehicle interior through the inside air sampling pipe to extinguish the fire. The present invention can be used not only in the above mechanical parking lot but also in a general self-propelled parking lot.

[0021]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, when a fire is generated inside or outside a vehicle placed in a parking lot and smoke is emitted, the smoke is forcibly sucked into the sampling pipe and fire. Touch the sensor. Therefore, it is possible to detect the fire 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 sent from the detector to the fire receiver, so that the fire can be detected in the initial stage of the fire occurrence. , It is possible to know which parking vehicle has a fire. Therefore, the fire extinguishing work can be performed earlier and more accurately than in the conventional example.
