Description

This invention is a movable booth that meets the requirements shown in Fire Prevention Prediction No. 622 notified by the Fire and Disaster Management Agency on November 2, 2018, and Fire Prevention Prediction No. 420 notified by the Fire and Disaster Management Agency on December 28, 2020. The present invention relates to a communication system having a movable booth.

In order to simplify the structure and construction of conventional movable booths, a mechanical fire extinguishing system (downward discharge type automatic fire extinguishing system for residential use) that operates without the use of piping or electrical wiring is used (patent document) (see 1).

That is, a conventional movable booth (such as a soundproof room) includes a housing and a door coupled to the housing, and an automatic fire extinguishing device is provided on the ceiling of the housing. The automatic fire extinguishing system is equipped with a heat sensing part that senses the heat caused by the occurrence of a fire, a fire extinguishing agent container filled with extinguishing agent, and a discharge nozzle that can discharge the extinguishing agent into the room when detected by the heat sensing part. It consists of Then, when the temperature inside the housing rises due to an outbreak of fire or the like, extinguishing agent is released from the release nozzle.

Patent No. 6764107

By the way, in conventional movable booths, it is possible to extinguish a fire inside the housing using an automatic fire extinguishing system, but if the automatic fire extinguishing system is mechanical, it cannot generate an electrical signal indicating the occurrence of a fire. . If you install detectors under the Fire Service Act (smoke detectors, heat detectors, flame detectors, etc.), there is a risk that you will not be able to receive special exemptions from the Fire Service Act (Fire Service Preliminary No. 622) for conventional movable booths. be.

Therefore, in order to generate an electrical signal indicating the occurrence of a fire, it is conceivable to install a pressure switch in the automatic fire extinguishing system, which opens and closes contacts depending on the drop in pressure inside the container during operation. However, there is a risk of inconveniences such as a complicated structure and an increase in pressure leakage factors, and it is not possible to issue a pre-alarm to notify of a temperature rise before a fire occurs.

Additionally, if a movable booth is connected to external equipment through wiring work, it may be considered part of a building outside the definition of "movable booth" as specified in the Fire and Disaster Management Agency notice, and cannot be protected by an automatic fire extinguishing system. It may be determined that there is.

To explain further, alarm systems that require wiring lose the freedom of installation that is an advantage of movable booths, and require wiring and piping for automatic fire extinguishing equipment, making installation work and equipment expensive. There is a risk that this may occur. Additionally, by performing wiring work, the movable booth is no longer something that can be easily removed with tools, etc., and the handling of the movable booth in terms of fire protection changes, and automatic fire extinguishing protection may no longer be possible.

When an automatic fire extinguishing system is provided with a transmitting function, the structure becomes complicated and reliability decreases. Furthermore, even if provided, it would be difficult to issue a pre-alarm due to the structure. It is difficult to remotely detect abnormalities within the movable booth and send signals by simply installing the current downward-discharging automatic fire extinguishing system for residential use.

An object of the present invention is to provide a movable booth or the like that can extinguish a fire that occurs inside the booth, as well as transmit a fire alarm and a pre-alarm. In addition, without compromising the conditions for a movable booth (conditions shown in the Fire and Disaster Management Agency notification) or complicating the configuration, it is possible to notify external equipment installed at a distance when the internal temperature has risen. The purpose is to provide a movable booth etc. that can transmit information.

The nozzle 23 is provided in the fire extinguishing agent container 19 near the heat sensing section 21 and below the fire extinguishing agent container 19, and when the heat sensing section 21 senses heat, the nozzle 23 discharges the extinguishing agent in the extinguishing agent container 19. It is released into the movable booth main body 3.

Note that the heat detection by the heat sensing section 21 and the discharge of the extinguishing agent from the nozzle 23 are performed by mechanical means that do not use electric power. That is, in the automatic fire extinguishing system 5, a low melting point metal is used for the heat sensing part, as in the automatic fire extinguishing system described in Japanese Patent No. 6764107, and a low melting point metal is used in the heat sensing part, and the temperature rise inside the movable booth main body 3 causes As the metal melts, extinguishing agent is released. As a result, the automatic fire extinguishing system 5 does not use any electrical elements, and the automatic fire extinguishing system 5 changes its mechanical configuration only when the temperature inside the movable booth main body 3 exceeds a predetermined value. and release extinguishing agent. It should be noted that an automatic fire extinguishing system that operates not by mechanical means but by electrical signals may also be used.

Furthermore, in the movable booth 1, the temperature detector 7 and the wireless transmitter 9 are separated and connected to each other by a wire (signal line) 26.

The predetermined temperature detected by the temperature detector 7 is at least lower than the temperature at which the automatic fire extinguishing device 5 releases the extinguishing agent into the movable booth 1 (movable booth main body 3) and higher than room temperature. One predetermined temperature. Note that the temperature at which the automatic fire extinguishing device 5 releases the extinguishing agent into the movable booth 1 (the movable booth main body 3) may be adopted as the predetermined temperature detected by the temperature detector 7.

In addition, when viewed in the vertical direction, the automatic fire extinguishing device 5 and the temperature detector 7 are installed in the center of the movable booth main body 3, and the heat sensing section 21 and the nozzle 23 are installed in the center of the automatic fire extinguishing device 5. It is located in

As the temperature detector 7, for example, a small and simple bimetallic temperature sensor (see FIGS. 5 and 6) is employed. The temperature sensor 7 can select the alarm temperature (the temperature at which the wireless transmitter 9 wirelessly transmits a predetermined signal) depending on the application. That is, the alarm temperature can be changed by replacing the temperature sensor 7 with a temperature sensor 7 having a different alarm temperature.

The bimetallic a-contact temperature sensor (temperature detector) 7 will be explained. As shown in FIG. 5, the bimetallic temperature sensor 7 is formed, for example, in a cylindrical shape. Furthermore, a wiring (wired) 26 extends from the bimetallic temperature sensor 7.

As shown in FIG. 6(a), the bimetallic temperature sensor 7 includes a housing 47, a pair of terminals 49 (49A, 49B), a bimetal 51, and a pair of contacts 53 (53A, 53B). configured. FIG. 6(a) shows a state at room temperature, and in the state shown in FIG. 6(a), the pair of contacts 53A and 53B are separated from each other.

FIG. 6(b) shows a high temperature state, and in the state shown in FIG. 6(b), the pair of contacts 53A and 53B are in contact with each other. As a result, the pair of terminals 49A and 49B are electrically connected to each other, and the wireless transmitter 9 wirelessly transmits a predetermined signal (transmits a fire occurrence signal) in the state shown in FIG. 6(b), for example.

Next, the operation of the transfer system 27 will be explained with reference to FIG. 4.

In the initial state, the a-contact temperature detector 7 monitors whether a fire has occurred within the movable booth body 3.

In the above initial state, when the temperature detector 7 detects that a fire has occurred within the movable booth body 3 (S1), the temperature detector 7 outputs a non-voltage contact signal to the wireless transmitter 9 (S3). At this time, the automatic fire extinguishing device 5 releases a fire extinguishing agent into the movable booth main body 3.

Next, the wireless transmitter 9 transmits a predetermined signal (fire information) to the wireless receiver (S5), the wireless receiver 29 receives the fire information, and transmits the signal to the external device (control panel or monitoring panel) 11. (S7).

Subsequently, when the external device (control panel or monitoring panel) 11 receives the signal (S9), the alarm section 31 of the external device (control panel or monitoring panel) 11 issues fire information (S11). . Note that the alarm unit 31 issues fire information using at least one of sound and light.

The movable booth 1 includes a movable booth body 3 that is connected to an external power supply only by electric wires, and an automatic fire extinguisher that releases extinguishing agent into the movable booth body 3 according to the temperature inside the movable booth body 3. The device 5 is configured to include a device 5. The movable booth 1 includes a temperature detector 7 that is provided separately from the automatic fire extinguishing device 5 and detects the temperature inside the movable booth body 3. Furthermore, when the temperature detector 7 detects that the temperature inside the movable booth body 3 exceeds a predetermined value, the movable booth 1 transmits a predetermined signal to an external signal using the electric power supplied by the electric wire. It is configured to include a wireless transmitter 9 that wirelessly transmits data to the device 11 and a wireless receiver 29 .

Thereby, in the movable booth 1, a fire occurring within the movable booth main body 3 can be extinguished. In addition, in the movable booth 1, electric wires extend from the movable booth main body 3, and power can be supplied by simply inserting the electric wire plug into an outlet, or by a method that can be easily removed with a tool etc. Electric power may be supplied by connecting the electric wire to an external power source, and the conditions for the movable booth 1 (conditions shown in the Fire and Disaster Management Agency notification) can be maintained. In other words, the movable booth 1 can be installed without compromising the fire protection regulations of the movable booth 1, and without any complicated construction work (no need for wiring or installation work for sensors under the Fire Service Act). 1 can be installed at low cost.

Further, in the movable booth 1, as shown in FIG. 6, the automatic fire extinguishing device 5 is provided with a temperature sensor 7, thereby preventing the configuration from becoming complicated. Furthermore, the fact that the temperature inside the movable booth body 3 has increased can be transmitted to the external equipment 11 installed at a remote location.

Moreover, according to the movable booth 1, by providing the temperature detector 7 and the wireless transmitter 9, the movable booth body has a simple structure that does not affect the operation or reliability of the mechanical automatic fire extinguishing system 5. It is possible to send a predetermined signal to indicate that the temperature within 3 exceeds a predetermined arbitrary value. Furthermore, it is possible to wirelessly transmit signals indicating the occurrence of a fire or the danger of a fire from a movable booth where wiring work for sensors is difficult under the Fire Service Act. As a result, a movable booth capable of fire monitoring can be installed with simple construction.

Furthermore, unlike a residential fire alarm, the movable booth 1 is provided with a wireless transmitter 9 separate from the temperature detector 7. This increases the degree of freedom in the installation location of the temperature sensor 7, and allows flexible response to user requests.

Furthermore, since the wireless transmitter 9 is of the LPWA type and is capable of long-distance transmission with low power, it is possible to communicate over a longer distance than with a residential fire alarm. Therefore, it is possible to reduce the number of terminals (external devices) used, and the installation space and cost can be reduced.

Furthermore, by separating the temperature detector 7 and the wireless transmitter 9, even if the environment in which it is used is worse than that of a home (for example, high or low temperatures), the sensor can withstand this environment. can be selected.

Further, in the movable booth 1, the automatic fire extinguishing device 5 does not include any electrical elements. Since the automatic fire extinguishing device 5 releases extinguishing agent only when the temperature inside the movable booth body 3 exceeds a predetermined value, the fire inside the movable booth body 3 can be accurately extinguished even during a power outage. can do.

In addition, in the movable booth 1, the predetermined temperature detected by the temperature detector 7 is set to a temperature lower than the temperature at which the automatic fire extinguishing device 5 releases the extinguishing agent into the movable booth main body 3 and higher than room temperature. at least one predetermined temperature. This makes it possible to send a so-called pre-alarm before a fire occurs.

That is, by appropriately selecting the temperature sensor of the temperature detector 7, it is possible to notify the administrator of the occurrence of a fire within the movable booth main body 3, the risk of a fire occurrence, or the extinguishment of a fire.

Note that two types of temperature detectors 7 may be provided to transmit a message indicating that a fire has occurred and to transmit a so-called pre-alarm before a disaster occurs. Further, instead of or in addition to the temperature detector 7, a detector (smoke detector) for detecting smoke within the movable booth main body 3 may be provided. Similarly to the temperature detector 7, the smoke detector also sends an alarm to the wireless transmitter 9 when the concentration of smoke within the movable booth main body 3 exceeds a predetermined threshold. By providing a smoke detector, it is possible to more reliably detect the occurrence of a fire in the movable booth body 3, and to take appropriate measures against smoking inside the movable booth body 3, where smoking is prohibited. can do.

Further, in the movable booth 1, as shown in FIG. 2(a), by providing the temperature sensor 7 on the decorative board 25, the degree of freedom in selecting the installation location of the temperature sensor 7 is increased. Further, as shown in FIG. 2(b), by providing the temperature detector 7 in the automatic fire extinguishing device 5, the number of steps required for installing the temperature detector 7 can be reduced.

In the transmission system 27, when the radio reception section 29 receives a predetermined signal wirelessly transmitted from the radio transmission section 9, the alarm section 31 issues an alarm. Thereby, it is possible to notify a person who is far away from the movable booth 1 that a fire has occurred in the movable booth 1 or that there is a risk of a fire occurring. The external shape of the movable booth 1 is not limited to a rectangular parallelepiped shape, but may be egg-shaped, cylindrical, or conical, and the automatic fire extinguishing device 5 and temperature detector 7 are installed above the movable booth. It will be done.

Note that in the movable booth 1, the electric wire may be eliminated and the wireless transmitter 9 may be driven by a battery provided in the movable booth 1. In addition, the wireless transmitter 9 is installed in a separate location that is not integrated with the movable booth 1, and the wiring between the wireless transmitter 9 and the temperature detector 7 can be easily removed using a tool or the like. May be connected.

In addition, as a reference example, as shown in FIG. 8, the wireless transmitter 9 and the wireless receiver 29 are deleted, and the temperature detector 7 detects that the temperature inside the movable booth body 3 exceeds a predetermined value. A predetermined signal may be transmitted by wire when the In FIG. 8, for example, a predetermined signal is transmitted from the transmitting section 57 (corresponding to the wireless transmitting section 9) to the receiving section 59 (corresponding to the wireless receiving section 29) via the in-house LAN 55 which can be easily removed. You can. In addition, in the configuration shown in FIG. 8, instead of using wiring that connects the in-house LAN 55 in a way that can be easily removed with a tool, the transmitting section 57 and the receiving section 59 are connected by wiring, and a predetermined signal is transmitted.
