Fire-fighting reporting system for fire suppression in apartment houses}

The present invention relates to a firefighting reporting system for extinguishing a fire in an apartment building in the field of firefighting technology. In addition, when a fire occurs, the fire is quickly detected through analysis and judgment of artificial intelligence, and the first extinguishment is started immediately at the beginning of the fire by the heat generated during the fire so that it can be extinguished immediately according to the detection result. It is possible to minimize fire damage, prevent human casualties in advance, and enable continuous management, monitoring and supervision through accurate and error-free information transmission and reception through wireless communication rather than wired communication. It is about a fire reporting system for

It is essential to respond to the risk of fire outbreaks in apartment buildings, including high-rise residential and commercial buildings, and to provide accurate and prompt fire alarm notification.

Everyone agrees on the need for a fire alarm and management system, and the conventional alarm method using a home device or fire receiver notifies a fire by a simple method of turning on an alarm or a lamp in response to a fire signal transmitted from a fire detector.

Then, firefighting work is performed according to the fire alarm. At this time, the fact that a fire has occurred is notified to the local fire station, and fire engines are dispatched immediately.

However, only information on the apartment where the fire occurred is delivered, and it is not known exactly at what point the fire occurred, so after arriving at the apartment, information is re-obtained from the managers and then moved to the point of ignition, so the initial suppression There is a problem with time delay.

In addition, since sprinklers are installed only on the ceiling of the kitchen where cooking utensils are located in each apartment unit, it is necessary to use a powder fire extinguisher provided for each household to extinguish the fire in the first place. It is difficult to find and even if it is found, it takes time to move to the ignition point and spray.

In addition, in the case of a stair landing, since it is not a structure capable of spraying fire extinguishing water capable of extinguishing a fire, initial fire suppression may be inefficient.

Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

1 and 2, a household fire detector 10 installed in each household of an apartment house, a fire hydrant controller 20 connected to the household fire detector 10 and installed at a fire hydrant, and installed at the fire hydrant, A household alarm 12 that is controlled by the fire hydrant controller 20 and sounds an alarm when a fire is detected, and a CCD camera 14 that is set at the landing where the fire hydrant is installed and transmits an image captured in real time to the fire hydrant controller 20 And, an automatic fire extinguisher 500 installed at the landing and connected to the fire hydrant controller 20 to perform a fire extinguishing operation according to a fire detection signal transmitted by the fire hydrant controller 20, and the fire hydrant controller 20 and wireless A management server 400 that is connected to and identifies which household a fire has occurred in, and a fire engine by sharing fire detection information transmitted by the management server 400 in real time and connected to the management server 400 by wire. It includes a competent fire server 30 to mobilize.

At this time, the fire hose 22 provided in the fire hydrant is connected through the fire water pipe 24 to receive fire water. At this time, the fire water pipe 24 includes a solenoid valve 26 and a water detection sensor (2400, see FIG. 3) is further installed, and the solenoid valve 26 is configured such that the opening and closing operation is controlled by the hydrant controller 20.

This is an urgent situation because the fire hose 22 is not filled with water through the fire water pipe 24 to prevent children from playing with the fire hose 22 or abused by juvenile delinquents. It is to overcome the problem that it is difficult to extinguish the fire in the early stage because it is not possible to spray fire extinguishing water immediately.

Therefore, when a fire is detected through the household fire detector 10 installed in the household, when the fire hydrant controller 20 transmits fire detection information to the management server 400, the number detection signal is detected through the number detection sensor 2400. It is configured to first detect whether there is water in the fire water pipe 24 or not, and transmit whether or not fire extinguishing water can be used immediately by confirming this.

Thus, when the firefighters are dispatched, if the solenoid valve 26 is opened by pressing the valve opening/closing switch 28 assigned to the fire hydrant controller 20, the fire extinguishing water can be used immediately, so that the fire can be immediately responded to.

On the other hand, if the fire extinguishing water is not detected, the line for supplying the fire extinguishing water is checked first, or a method for supplying the fire extinguishing water in another way is reviewed in advance, and then it helps to establish a plan to participate in the firefighting operation.

To this end, as shown in the example of FIG. 3, a water detection sensor 2400 is further installed on a part of the length of the fire hydrant pipe 24, and the water detection sensor 2400 is electrically connected to the fire hydrant controller 20 to fire the fire water pipe ( 24) It is configured to detect in real time whether water is filled or not inside.

The water detection sensor 2400 passes through the fire extinguishing water pipe 24 and is screwed to communicate with the inside.

In addition, the water detection sensor 2400 includes a sensor housing 2412 having an empty interior and an open upper end and a screwed lower end, a locking jaw 2414 protruding from the inner diameter of the sensor housing 2412, and the A fluidizer 2418 having a sensor flange 2416 caught on the locking jaw 2414 and flowing according to water pressure, and a pressure inducing groove formed in a concave shape on the lower surface of the fluidizer 2418 so that the water pressure is concentrated ( 2420), a semicircular protrusion 2422 convexly protruding from the top surface of the fluidizer 2418, a sensor cover 2424 fastened to seal the open top of the sensor housing 2412, and the sensor cover A pressure sensor 2426 that is in close contact with the inner surface of the 2424 and transmits a pressure detection signal when the semicircular protrusion 2422 is in contact, and a lead wire electrically connecting the pressure sensor 2426 and the fire hydrant controller 20 ( 2428) and a coil spring 2430 interposed between the sensor flange 2416 and the sensor cover 2424 to elastically move the fluid element 2418.

Thus, when water is filled on the fire hydrant pipe 24, the semicircular protrusion 2422 of the fluidizer 2418 receives water pressure and pressurizes the pressure sensor 2426, and transmits the pressure signal to the fire hydrant controller 20, judge that there is no

However, since the fluidizer 2418 is not pressurized when the water is not filled, the pressure sensor 2426 is not pressurized while being pushed by the coil spring 2430, so the hydrant controller 20 recognizes that there is no pressure signal. It makes you aware that this has happened.

Accordingly, it is possible to automatically check firefighting facilities at all times.

On the other hand, the CCD camera 14 is controlled to capture images in real time, compress and store images captured in a predetermined time unit, and transmit the stored compressed images to the fire hydrant controller 20.

In this case, the captured compressed image is transmitted to the management server 400 under the control of the fire hydrant controller 20, and is decompressed in the management server 400 and then read by artificial intelligence. This captured image is inside the landing, When an unusual situation is created inside the stair landing, the management server 400 primarily sees that there is a feature point and analyzes whether there is a possibility of a fire by comparing and analyzing it with an image related to a learned fire.

This analysis can be performed by artificial intelligence using deep learning techniques.

In addition, in the case of the automatic fire extinguisher 500 installed at the landing, it can be designed to be electrically connected to the fire hydrant controller 20 and operated together when transmitting a fire detection signal, and they are designed to receive commercial power. do.

Of course, in the case of the automatic fire extinguisher 500, even before it is controlled to be operated by the fire hydrant controller 20, it may be operated in advance by high heat generated due to a fire.

Such an automatic fire extinguisher 500 may have the same structure as the example of FIG. 4 .

The automatic fire extinguisher 500 is disposed in front of a box-shaped unit housing 510 with one side open, a rectangular first tube 520 built in the unit housing 510, and the first tube 520. pressure plate 530, the extinguishing powder 540 charged in front of the pressure plate 530, the rectangular second tube 550 disposed in front of the extinguishing powder 540, and the front side of the second tube 550. A grate cover 560 hooked to the open portion of the unit housing 510 to cover the lattice cover 560, and a heat transfer pipe 570 passing heat through the lattice cover 560 to the first tube 520 And, a heater 580 connected to the heat transfer pipe 570, and a heater controller fixed to the outer wall of the unit housing 510 to operate the heater 580 at the same time as the detection signal of the fire detector 200 is transmitted ( 590).

At this time, methane gas is injected into the first and second tubes 520 and 550 in a compressed state, and when heated and reached a temperature above a certain level, it explodes and destroys structures in front, such as the grate cover 560 and fire extinguishing powder 540. ), the pressure plate 530 is scattered through the open portion.

In addition, the extinguishing powder 540 is charged in a sealed state wrapped in a thin vinyl, and the pressure plate 530 exists to uniformly push and scatter the extinguishing powder 540 when the first tube 520 explodes.

In addition, as shown in an enlarged view of the grate cover 560, a portion of the circumferential end is coupled to the unit housing 510 with a hook 562, and ribs 564 and segments 566 are continuously formed in the horizontal and vertical directions. It consists of a relatively thin rib 564 is configured to fall well during explosion.

In particular, since holes are formed between the ribs 564, heat can be easily and quickly transferred toward the second tube 550 in case of fire.

In addition, the heat transfer pipe 570 is a means for quickly expanding the first tube 520 by forming a space so that the heat received in the event of a fire is rapidly transferred to the first tube 520 .

Thus, fire extinguishing powder 540 is poured forward by the first and second tubes 520 and 550, which receive heat at the beginning of the fire and explode after expansion, thereby immediately suppressing the fire origin, thereby preventing the fire from increasing and preventing safety accidents.

In addition, since the heater 580 and the heater controller 590 may not expand and explode at the beginning of a fire, the heater controller 590 operates the heater 580 by receiving a control signal from the fire hydrant controller 20, and the heater ( 580), the heat transfer pipe 570 is heated while heating up, and can be induced to cause an explosion forcibly.

Here, the unit housing 510 is based on 100 parts by weight of ABS (acrylonitrile-butadiene-styrene copolymer) resin, 5 parts by weight of lithium silicate, 30 parts by weight of silicone resin, 10 parts by weight of ammonium persulfate, 5 parts by weight of silicon nitride, It is preferably prepared by molding a mixture of 10 parts by weight of chondroitin-sulfuric acid, 5 parts by weight of silicon carbide, 5 parts by weight of calcium methyl silanetriate, and 5 parts by weight of titanium dioxide.

At this time, the ABS resin is a resin material with high heat resistance and high durability; Silicone resin is added to provide cushioning and elasticity; Lithium silicate contributes to the formation of a waterproof coating film and enhances stain resistance; Ammonium Persulfate is added to increase preservation by controlling acidity to prevent oxidation; Silicon nitride is light and has a low thermal expansion rate, and is excellent in strength at room temperature or high temperature, toughness against fracture, thermal shock resistance, oxidation resistance, and corrosion resistance; Chondroitin-sulfuric acid is added to prevent drying and to keep the adhesiveness stable for a long period of time; Silicon carbide has high thermal conductivity in addition to resistance to dissolution, resistance to melting, and resistance to oxidation.

And, calcium methyl silane trioate increases chemical resistance and chemical resistance; Titanium dioxide is added to increase heat dissipation efficiency and increase the heat transfer area; Petrolatum provides longevity, that is, durability by suppressing corrosion resistance, its erosion resistance and crack generation.

In addition, as shown in the examples of FIGS. 5 and 6, it is mounted on the fire hydrant controller 20 to prevent wireless communication errors, improve transmission quality, and increase reception sensitivity by minimizing transmission errors, noise, and failure during wireless communication. The transmit antenna module is an antenna module that oscillates circular polarization, and the rotation direction of circular polarization can be arbitrarily selected as either left or right.

In this case, the reason for limiting the use of circular polarization is to realize the reception antenna 3000 installed in the management server 400 as a patch antenna, and above all, two or more channels at one frequency by timing control. This is because it can transmit/receive, is strong against obstacle noise, has high building permeability, is strong against multiple reflection interference, and has low polarization loss.

For this reason, in the present invention, the transmitting antenna module mounted on each fire hydrant controller 20 intentionally uses a module that generates circular polarization.

Also, the receiving antenna 3000 is a patch antenna, and has a form in which power is supplied in various forms after a metal pattern having a specific shape is formed on a microstrip substrate.

In particular, since signal reception for RF circular polarization is excellent, it is possible to increase antenna gain (gain), so that accurate control signal reception is possible and error occurrence is reduced.

To this end, the receiving antenna 3000 is installed on the roof of the management office equipped with the management server 400 and then connected to the management server 400 .

The receiving antenna 3000 includes a first dielectric housing 3112 having a rectangular cylinder shape with an open top and a closed bottom, and a second dielectric housing 3114 having the same structure as the first dielectric housing 3112. It is seated on the top of the first dielectric housing 3112.

A 'TT'-shaped transmission terminal 3116 is fixed to the lower surface of the first dielectric housing 3112, and the transmission terminal 3116 is connected to the management server 400 through a transmission line.

In addition, the first and second dielectric housings 3112 and 3114 are composed of dielectric materials to reduce propagation loss, and 25 parts by weight of dimethylpolysiloxane, 10 parts by weight of barium titanate (BaTiO ₃ ), 4 parts by weight based on 100 parts by weight of epoxy resin. - It is prepared by mixing 5 parts by weight of 4-Diazodiphenylamine sulfate, 10 parts by weight of silicon dioxide, and 5 parts by weight of toluene diisocyanate and molding it into a square frame shape.

At this time, the epoxy resin is a base resin for implementing a non-conductive dielectric so as not to hinder antenna gain loss, dimethylpolysiloxane is added to increase antenna efficiency by interaction of electromagnetic waves occurring in the microstructure, and barium titanate is It is added to secure and maintain a high permittivity.

And, 4-Diazodiphenylamine sulfate is a substance corresponding to CAS number 4477-28-5, and it enhances corrosion resistance, heat resistance, and fatigue limit by strengthening chemical resistance and chemical resistance while preventing discoloration. maintain longevity through

In addition, silicon dioxide is added to increase antenna gain by reducing radio interference, and toluene diisocyanate is added to increase surface gloss and prevent contamination and deterioration.

In addition, an elevating motor 3118 is fixed to the inner bottom surface of the first dielectric housing 3112, and a ball screw 3120 is connected to a rotating shaft of the elevating motor 3118, and the ball screw 3120 They are vertically arranged passing through the inner bottom surface of the second dielectric housing 3114 .

Here, a screw bush 3122 is insert-molded at the center of the inner bottom surface of the second dielectric housing 3114, and the ball screw 3120 is screwed through the screw bush 3122.

In particular, the upper end of the ball screw 3120 occupies a position raised to about 1/2 of the upper and lower length of the second dielectric housing 3114, and the stopper 3124 is fixed to the upper end, so that the second dielectric housing (3114) is designed to limit the lift height.

In addition, lower pattern antennas 3200 having different shapes are fixed around four surfaces of the first dielectric housing 3112, and sliding grooves 3210 are formed inside the lower pattern antenna 3200.

In this case, the sliding groove 3210 has a shape in which an upper end is open and a lower end is blocked.

In addition, the lower pattern antenna 3200 has a structure in which a conductive metal is plated on the surface of an injection-molded body made of ABS resin in order to increase design freedom and facilitate installation position and operation.

At this time, the plating may be copper, silver, etc., and if the injection body is three-dimensional, all surfaces are plated.

In addition, the lower pattern antenna 3200 may have various shapes such as 'I' type, 'ㄹ' type, 'C' type, and 'ㅁ' type in order to increase reception sensitivity. It took this good shape.

In addition, the upper pattern antenna 3300 corresponding to the lower pattern antenna 3200 is fixed around the four surfaces of the second dielectric housing 3114, but has different lengths, and the upper pattern antenna 3300 Sliders 3310 inserted into the sliding grooves 3210 are integrally formed at the lower end of each.

In this case, all of their contact surfaces must be plated with a conductor so that the contact state can be maintained even during the sliding process so that current can always be maintained.

Accordingly, the second dielectric housing 3114 rises according to the rotation of the lifting motor 3118. At this time, the second dielectric housing 3114 does not rotate because of the pattern antennas and only rises in the vertical direction.

At this time, since the upper pattern antenna 3300 also rises, the slider part 3310 also rises, and the reception efficiency, that is, the antenna gain, is increased due to various height differences of the pattern antenna, thereby enabling stable communication.

This is operated by the management server 400 so that the lifting motor 3118 is connected to the management server 400 to be described later and moves up when the reception sensitivity decreases according to the control signal thereof.
