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 extinguishing 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 the parking section of the parking stage arranged in multiple stages by using transportation means such as elevators and traveling carts. 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 is activated. 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. Further, in the conventional fire extinguishing system, since the extinguishing agent is jetted toward the outer surface of the vehicle, it is not possible to directly extinguish the fire inside the vehicle. Therefore, it is difficult to extinguish the fire at the stage of the initial fire. Furthermore, even though the conventional fire extinguishing system is not in a fire condition,
For example, even if smoke is emitted from the cigarette husk that disappears naturally, if the smoke is caught, it may be immediately judged as a fire and a fire alarm may be issued.

In view of the above circumstances, the present invention is capable of early and accurately detecting a fire that has occurred inside a vehicle, and
The purpose is to know which vehicle has a fire. Another object is to allow the fire extinguishing in the vehicle directly.

The present invention includes: A: Extinguishing a vehicle fire in a parking lot characterized by comprising an inside air sampling pipe for communicating with the interior of the vehicle and a heat sensor provided at the tip of the inside air sampling pipe. Depending on the system, also B:
A portable smoke detector installed in a vehicle in a parking lot, an inside air sampling pipe for communicating the detector with the inside of the vehicle, a heat detector provided at the tip of the inside air sampling pipe, and the inside air A vehicle fire extinguishing system in a parking lot, which is connected to a sampling pipe and is activated based on the detection of a fire by the detector, and

Further, C: a transportable wireless smoke detector having a parking address of each parking portion of the parking lot and a vehicle of the parking portion and having its own address, the detector and the vehicle. The interior air sampling pipe for communicating with the interior of the room, a heat sensor provided at the tip of the interior air sampling pipe, and a fire reception unit in which the parking address and the self address are stored. By the vehicle fire extinguishing system of the parking lot, or D: the parking address of each parking part of the parking lot, and the vehicle installed in the parking part, and
A transportable wireless smoke detector having a self-address, an inside air sampling pipe for communicating the detector with the interior of the vehicle, a heat detector provided at a tip of the inside air sampling pipe, and the inside air sampling pipe A fire extinguishing system for a parking lot, characterized by comprising: a fire extinguishing device that is activated based on the detection of a fire by the detector, and a fire receiving unit in which the parking address and the self address are stored.
Therefore, the above-mentioned object is to be achieved.

[0009]

When a fire occurs inside the parked vehicle, smoke in the room is sucked through the inside air sampling pipe and comes into contact with the fire detector. Then, the fire detector outputs and the fire signal and the self address are wirelessly transmitted to the fire receiver. Furthermore, if the temperature in the room rises due to a fire,
The heat detector detects a fire and a fire signal is sent to the fire receiver. In this way, when the fire receiving unit receives the fire signals from both the sensors, the fire alarm is issued and the fire extinguishing device is activated, so that the fire extinguishing gas or the like is discharged into the vehicle cabin through the inside air sampling pipe. Since the parking address of the parking section and the self-address of the fire detector are entered in advance in the fire receiving section as a comparison table, which parking section of the vehicle has the fire generated by the fire signal? Can know.

Department.

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. Then, outside the vehicle of the vehicle G, for example, the roof 1
The mounting plate 101 is fixed to the upper surface of the base plate 00. The glass window 63 is opened, and the nozzle 104 is inserted into the vehicle interior R from between the window 63 and the window frame 65. Then, the glass window 63 is set to A63.
When the tube 105 is raised in the direction, the tube 105 is sandwiched between the glass window 63 and the window frame 65. In this state, the vehicle G automatically moves to the empty parking portion 2a via the elevator 8 and the traveling carriage 5.

As shown in FIG. 6, when there is an entry (S1),
The administrator inputs the self-address of the wireless smoke sensor W ₁ mounted by utilizing the bar code and the numeric keypad of the management unit M, the interface I / F22 the own address of the sensing device W ₁ read RAM22 from 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 (S3, S4), the parking address is read from the interface I / F 22 and stored in the RAM 22. The self address and the parking address are stored so as to be a comparison table (S5).

The detector 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. In this state, the valve 103 is opened and the pump P is activated, so that the air in the room R is forcibly blown into the detection box 102 through the pipe 105. Then, the air is discharged to the outside of the box 102 after coming into contact with the smoke sensor W ₁ . At this time, since the valve 106 is closed, the sucked air in the room R does not reach the fire extinguisher 108. When a smoke is generated in the room R due to the cigarette smoke 120 or the like and smoke S is emitted, the smoke S is emitted from the nozzle 10
4 is forcibly blown into the tube 105 and comes into contact with the smoke sensor W ₁ . Therefore, the detector W ₁ detects a fire, and the detection unit FS outputs a fire signal.

Then, as shown in FIG. 5, when a fire occurs in the room R, the smoke detector W ₁ contacts the smoke to detect the fire, and the output of the detection unit FS exceeds the fire discrimination standard ( K1 YES), read self address from ROM 12 (K
2) Communication unit TX1 via interface I / F12
From 1 the fire signal and the self-address are wirelessly transmitted to the fire receiving unit RE (K3). Similarly, the control unit 109 stores the fire signal from the smoke detector W ₁ .

When the fire spreads and the temperature of the room R becomes high, the heat detector 300 detects the fire and sends a fire signal to the fire receiver RE through the communication unit TX12 as well as the smoke detector W _1. Send to sensor W ₁ . When the smoke detector W ₁ receives the fire signal from the heat detector 300 that is a pair, the smoke detector W ₁ sends the fire signal to the communication unit TX12 via the interface I / F 13 according to the AND condition of the smoke fire signal and the heat fire signal. Sending (K4) sends a signal to the control unit 109 to close the valve 103 and open the valve 106. Therefore, the fire extinguishing gas F, for example, CO ₂ gas is ejected from the nozzle 104 to start extinguishing the fire in the room R. At this time, both detectors display a fire on the display unit DS via the interface I / F 14 (K5), indicating that the room R is filled with gas.

When these fire signals enter the communication unit TX21 to the fire receiving unit RE, the self-address of the detector W, 300 is read through the interface I / F21 and RA
The parking address corresponding to the address is read from the comparison table of M22 (F2). After that, interface I / F
The display unit DP and the alarm unit AM are operated via the I / F 24 and the I / F 24 (F4) to display and warn the occurrence of a fire. When the fire signal from the smoke sensor W ₁ is not received from the heat sensor 300 to the fire receiving unit RE within a predetermined time, the manager needs to confirm the parking unit 2 at the parking address. ..

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 pipe 105, then removes the mounting plate 101 from the roof 100, and detects the smoke detector. Give the mounting plate 101 with W etc. to the manager. When there is such departure (D1), the fire reception unit RE reads the parking address of the vehicle G carried out from the management unit P via the interface I / F 22, and reads the parking address and the corresponding self address in the RAM 22. Erase (D2).

The embodiment of the present invention is not limited to the above, and may be configured as shown in FIG. 7, for example. The difference between this embodiment and the above embodiment is that, in addition to the inside air sampling pipe 105, an outside air sampling pipe 201 communicating with the outside D of the vehicle is connected to the smoke detector W _1, and the tip of the inside air sampling pipe 105 is connected. That is, 105a is flattened. Furthermore, the wireless smoke detector W ₁
Are arranged in a detection box 102 fixed to a mounting plate 101. The inlet of this detection box 102 is a valve (solenoid valve)
It is connected to the inside air sampling pipe 105 with 103, and
The outlet is connected to the pump P.

The tip portion 105a of the pipe 105 is flattened as shown in FIGS. 7 and 8, and the tip thereof has a suction port 104 and a heat detector 30 which are inserted into the interior R of the vehicle G.
A heat-sensitive section of 0 is provided. A control device 109 including a transmission unit and a driving unit is provided above the detection box 102. The inside air sampling pipe 105 is connected to the outside air sampling pipe 201 via a connecting pipe 200 with a check valve 301. Intake holes 201a for sucking the air B outside the room D are formed in the pipe 201 at intervals in the longitudinal direction. Both ends of the outside air sampling tube 201 are fixed to the mounting plate 101 via columns 202.

In this embodiment, since the valve 103 is opened and the pump P is started at the time of fire monitoring, the room R
The air (inside air) A is forcedly blown into the detection box 102 through the pipe 105, and the air (outside air) B outside D is also forcedly blown into the detection box 102 through the pipe 201. Be done. 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 . Further, when the fire spreads and the temperature inside the vehicle becomes high, the heat sensor 300 detects the fire and sends a fire signal to the fire receiving unit RE. In this way, when the fire signal is received from both detectors, the fire receiving unit RE determines that there is a fire and activates the fire extinguishing apparatus 108.

Further, since the tip portion 105a of the tube 105 is flat, it is possible to narrow the gap between the glass window 63 and the window frame 65 which occurs when the inside air sampling tube 105 is held. Further, instead of holding the tube 105 between the glass window 63 and the window frame 65, the tube 105 may be inserted and held in a pull-out hole used for installing an antenna or arranging an electric wire, or may be directly sandwiched and held by a door. Good.

Further, the fire extinguisher is not limited to the gas fire extinguisher, but it is also possible to use, for example, a foam fire extinguisher system. The present invention can be used not only in the above-mentioned indoor mechanical parking lot but also in a general self-propelled parking lot.
