Description

Evacuation facility management system for firefighting in case of apartment fire

The present invention relates to an evacuation facility management system for firefighting in the event of a fire in an apartment house, and more particularly, not only provides an evacuation facility for residents to safely evacuate in the event of a fire, but in particular, in the event of a fire, the elevator is burnt out despite the fact that it cannot be used Firefighting evacuation in the event of a fire in an improved apartment house to prevent inadvertent human accidents that occur while trying to use it in advance to reliably protect residents from fire, as well as to prevent communication failure by establishing a Wi-Fi network using satellite communication in an emergency. It relates to a facility management system.

In general, an apartment house is equipped with an entrance door, a veranda is installed inside the living room, and a safety railing for fall prevention is installed on the veranda.

However, the recent high-rise (over 30 stories) and residential-commercial complexes of apartment buildings have the advantage of being able to look down on the surrounding landscape from the inside and having various convenience facilities inside one building. If suppression is difficult, it has the disadvantage of leading to not only great property damage but also human casualties.

Of course, if the main door and the emergency exit are open when the first fire occurs, you may try to escape through the main entrance and the emergency exit.

However, if the emergency exit and the main entrance are blocked with flames, there is a problem that the resident trapped in the apartment building has to wait for death while trapped or jump over the safety railing for fall prevention as a desperate measure.

On the other hand, in order to solve this problem, there is a method of avoiding the body from a fire by using a stiffener installed on the veranda. Due to the burden of carrying the user's weight, there is a limit in that it is impossible to shake off the fear of fire as well as the anxiety caused by the use of the stiffener.

In addition, when a fire occurs in a building such as an apartment house, a fire fighting system for detecting and extinguishing the fire is provided.

The conventional fire fighting system as described above includes a detector for detecting the occurrence of a fire, a controller for operating an alarm system or a sprinkler and a fire shutter, etc. when the occurrence of a fire is detected by the detector, and a sprinkler operated by the controller It is composed of firefighting equipment, etc.

These are to extinguish the fire by spraying fire extinguishing water at a set position when a fire occurs.

With such a system, in each household in the apartment house, there is no information on the vulnerability to fire in each household in the apartment house, so when a fire occurs, it is difficult to quickly extinguish it.

In particular, various types of fire detectors are provided in households, but there is no means to detect fires occurring at stair landings other than households, so countermeasures are required.

In addition, in the event of a fire, there is no way to check whether the inside of the elevator is burned out, so if you make a mistake, a large-scale accident may occur during the elevator boarding process.

In addition, in an emergency such as a natural disaster, the communication network is cut off, and there is a high risk of more safety accidents and casualties.

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

The system according to the present invention can monitor both the inside of the apartment building as well as the outside stair landing and the fire that occurs outside each building. Evacuate, but provide an evacuation facility system that can safely evacuate until the final rescue.

Accordingly, the system according to the present invention implements a sensing structure to have sensing characteristics including a fire detector installed in each household as well as a fire detector installed outside the household, and implements an evacuation route in conjunction with the sensing structure, and an evacuation facility is provided. It is characterized in that it is configured to be driven.

More specifically, as illustrated in FIGS. 1 to 3 , a fire alarm detector 100 installed in each household fire hydrant of an apartment house, an alarm 110 mounted to the fire alarm detector 100 , and the fire alarm detector A heat detector 120 connected to 100 and installed in each household, a smoke detector 130 connected to the fire alarm detector 100 and installed in each household, and a memory mounted on the fire alarm detector 100 A built-in alarm controller (CTR), a sound detector 140 that is controlled by the alarm controller (CTR) and recognizes a specific frequency, is installed at the stair landing for each household and the sound detector 140 can detect a fire A detection alarm 700 that outputs a bell sound, a management server 300 that is connected to the alarm controller (CTR) and operates the fire alarm detector 100 through the alarm controller (CTR) when a fire occurs, and the rooftop of each building The roof door electronic lock 200 installed on the door and opened according to the control signal of the management server 300 when a fire occurs, and the shelter 400 provided on the roof of each building according to the control signal of the management server 300 when a fire occurs. It includes a shelter-in-place lock 400 for switching to a drivable state.

At this time, it is preferable that the fire alarm detector 100 has water resistance, waterproofness, and antifouling properties to enhance corrosion resistance, thereby achieving a longer lifespan, and furthermore, having heat resistance and fire resistance so as not to be vulnerable to fire.

To this end, the outer surface is based on 100 parts by weight of the liquid melamine resin, aluminum hydroxide 25 parts by weight, zirconium 10 parts by weight, boron nitride 15 parts by weight, sericite powder 10 parts by weight, isocyanurate 5 parts by weight, decarburization 15 parts by weight of lithium powder, 15 parts by weight of silicon carbide powder, and 10 parts by weight of pyrometric acid are coated with a mixed coating solution.

In this case, the liquid melamine resin is added to strongly suppress the surface peeling of the coating layer by maximizing the adhesive force and to strengthen the fire resistance, and the aluminum hydroxide prevents hydrophobicity of the polymer and induces hydrophilicity to increase the bonding strength and enhance incombustibility. Zirconium is added to increase fire resistance, corrosion resistance, and non-combustibility by forming a protective film made of oxide or nitrogen oxide by combining with oxygen in the air during a fire.

In addition, boron nitride is added to enhance the heat resistance by increasing the thermal conductivity of the brick, effectively reflecting heat and maintaining heat dissipation through this, and sericite is a hydrophilic mineral that increases the adhesion area to the surface and doubles the adhesion. It is added to enhance binding properties and increase durability.

In addition, isocyanurate is added to minimize foaming of the dough and remove air bubbles, and to increase impact resistance and weather resistance; Tantalum is a transition metal and has acid resistance, which enhances anti-pollution and corrosion resistance.

In particular, silicon carbide is added to enhance heat dissipation and adhesiveness and, above all, to suppress shrinkage deformation during molding; Pyromethic acid is added to suppress heat shrinkage and strengthen slip properties to improve moldability and improve durability during raw material molding.

On the other hand, as in the example of FIG. 4 , the detection alarm 700 is configured as a portable type so that it can be operated without commercial power.

The detection alarm 700 shown in FIG. 4 includes an alarm case 710 having an enclosure shape, a flame detection unit 720 protruding from the center of the lower end surface of the alarm case 710, and the alarm case 710. A fixing block 730 fixed to the inner ceiling surface, a square bar 740 hinged to the center of the lower end surface of the fixing block 730, and a spring (SP) bound to the lower end of the square bar 740 and , The wire 750 fixed to the end of the spring (SP), the striking weight 760 bound to the lower end of the wire 750, and the striking weight 760 are disposed on both sides within the rotation radius of the alarm A pair of alarm bells 770 fixed to the inner bottom surface of the case 710 and the striking weight 760 are bound to the center of the lower end and extended to penetrate the flame detection unit 720 and then are bound to the striking weight ( A binding chamber 780 arranged and fixed in the direction of gravity so that the 760 is not moved, and a pair of first and second pairs arranged in an N-pole-S pole shape on the square bar 740 and fixed at intervals up and down Magnets 790 and 792 and the third magnet M3, which is disposed to be opposed to the N pole of the first magnet 790, is arranged to act as a repulsive force and is fixed to the inner wall surface of the alarm case 710; The third magnet M3 and the fourth magnet M4 and the S pole opposite to the S pole of the second magnet 792 are located below the third magnet M4 and fixed in the same form, so that a repulsive force is applied to each other. and a fifth magnet (M5) arranged to be arranged and fixed to the inner wall surface of the alarm case 710, and a sixth magnet (M6) fixed in the same form on the upper side in parallel with the fifth magnet (M5) do.

At this time, it is preferable that a plurality of through holes 722 are formed on the peripheral surface of the flame detection unit 720 .

This is to transfer heat directly to the binding chamber 780 as much as possible when heat is transferred by the flame so that the binding chamber 780 is easily broken.

In addition, a plurality of through-holes 772 are also formed on the circumferential surface of the alarm case 710 at the position where the alarm bell 770 is installed, so that the sound of the bell spreads far and wide.

Thus, when the binding chamber 780 is cut due to fire, the spring SP, which has been pulled to some extent by the binding chamber 780 due to the impact, is restored and the wire 750 is shaken, which is a striking weight having a weight. The alarm sound is sounded while the alarm bell 770 is hit by making the 760 move like a pendulum motion.

In this process, since a repulsive force is generated between the magnets, the striking weight 760 after striking repeats the striking action while moving back and forth for a considerable time.

Due to this, an alarm sound is sufficiently issued, and this alarm sound is detected by the sound detector 140 of the fire alarm detector 100 installed in the fire hydrant located adjacent to the fire hydrant, and when the sound detection is completed, the alarm controller (CTR) is sent to the management server ( 300) to indicate that a fire has occurred.

At this time, since the alarm controller (CTR) and the management server 300 are connected by wire, it is possible to immediately check in which building the fire occurred, and by issuing the alarm 110, the residents are evacuated quickly. do.

In particular, since the rooftop door is mainly locked with an electronic lock to prevent the escape of teenagers, the management server 300 confirming the fire unlocks the electronic lock 200 of the roof door connected by wire with the alarm controller (CTR) of the corresponding agreement.

In this case, the roof door electronic lock 200 is connected in parallel with the alarm controller (CTR) for each household in the corresponding building and is configured to give an unlocking signal through the alarm controller anywhere in the building. in order to block

Therefore, in general, it is basic that the management server 300 controls to give a signal to open the roof door lock 200 through the alarm controller that has transmitted the emergency signal.

In addition, when a fire occurs, the management server 300 activates the shelter electronic lock 400 in a wireless communication method.

Of course, it is also activated by pressing the emergency power button (not shown) provided in the shelter 410 provided on the roof by people who have evacuated to the roof in case of an emergency.

Therefore, the shelter electronic lock 400 is equipped with a wireless communication module to enable wireless communication with the management server 300, and a unique code is assigned to each of them. The server 300 activates the shelter electronic lock 400 provided on the roof of the building.

At this time, the shelter electronic lock 400 is provided in the shelter 410 installed on the roof, as illustrated in FIG. 3 .

The shelter 410 is in the form of a lifting elevator, and is configured to be liftable along a ball screw 420 installed from the ground to the roof on one side of each building and a guide rod 430 installed in parallel with the ball screw 420 .

In this case, the outer surface of the shelter 410 is coated with a fire protection liquid, a door 440 is provided for boarding, and an emergency power source is installed in the basement of the building.

The emergency power is not an apartment commercial power, but an emergency power generation system, and is driven by an emergency power button switched by the evacuation shelter electronic lock 400 .

Therefore, even if the corresponding copper is lost, it can be safely driven.

In addition, when emergency power is applied to the operation of the shelter 410 , the control panel 450 exercises all control related to the control, and the driving motor M is driven by selecting one of the first floor and rooftop buttons after boarding and pressing the button similar to the elevator. As the gearbox (G) is operated, it is operated so that the shelter (410) can go up and down on the ball screw (420).

As such, according to the present invention, fire detection and evacuation can be performed together, thereby reducing human casualties.

In addition, the vanishing sensor 10 as in the example of FIGS. 5 and 6 is further installed inside the elevator, and the vanishing sensor 10 is equipped with a short-range wireless communication module as a heat sensor. is configured to output

Then, the shelter electronic lock 400 installed in the tower of the elevator is set to receive the specific signal, and as soon as it receives the signal, it recognizes that it is a fire and sends a signal to the management server 300 to respond immediately.

In this case, since the signal transmitted by the shelter electronic lock 400 includes a unique code, that is, an identification code, the management server 300 can immediately know which elevator has been burned down.

Here, the disappearance detector 10 sent a detection signal because it means that the inside of the elevator is overheated and burned due to a fire, it is determined that this is lost.

On the other hand, in the present invention, it is characterized in that it is configured to be detachable and can be installed without pulling commercial power through a replaceable battery usage method, so that it is not limited by the installation location.

To this end, in the present invention, a fixing unit 50 is included so that the loss detector 10 can be easily separated and mounted.

The fixing unit 50 includes an attachment sheet 51 fixed to the inner wall of the elevator, a cover 52 attached to the attachment sheet 51, and a base housing 53 covered with the cover 52 and , a protrusion 54 protruding in a rectangular shape from the opposite surface of the cover 52 of the base housing 53, a pin fixing part 55 protruding again at a distance from each other from the surface of the protrusion 54, and the pingo A fixing pin 56 fixed across the top 55, a 'C'-shaped insertion piece 57 fitted to and bound to the fixing pin 56, and the insertion piece 57 are integrally formed and lost A side base 58 screwed to the bottom surface of the sensor 10, and one side of the insertion piece 57 built into the base housing 53 and inserted into the fixing pin 56 when the insertion piece 57 is inserted into the fixing pin 56 It includes a locking hole 59 that is fitted into the lock and fixed.

At this time, the attachment sheet 51 is a gel-type sheet.

This attachment sheet 51 is not liquid, unlike general adhesives, has high fixing power, and has strong waterproof, heat resistance, antifouling, erosion resistance, weather resistance, and water resistance, so that it is not easily deteriorated even after long-term use in an external environment to achieve long life. It should be structured so that

Otherwise, it is easily deteriorated and is easily detached from the attachment surface, or cracks are generated and fall off.

In addition, if the adhesive force is hardened too strongly, for example, if it is hardened rigidly like an instant adhesive, the fixing force is very high, but there is a limit to damage the attachment surface, so there is a disadvantage that long life cannot be achieved.

To this end, the attachment sheet 51 is ethyl acetate 5 parts by weight, hydrocolloid 25 parts by weight, PEBAX (Polyether-block-amide) 10 parts by weight, triphenylphosphine 5 parts by weight, CZ based on 100 parts by weight of the epoxy resin. (N-cyclohexybenzothiazole-2-sulfenamide) 5 parts by weight, 5 parts by weight of sodium xylenesulfonate, 5 parts by weight of 2-phenylimidazole, 10 parts by weight of polytetrafluoroethylene, and 15 parts by weight of silicone resin After ringing, use the one molded into a sheet shape.

Here, ethyl acetate is added to prevent agglomeration or micro-dispersion of the mixture in the process of dispersing the mixture to secure surface and back uniformity.

In addition, hydrocolloid is added to make a gel-like sheet and maintain a wet state to confirm adhesiveness for a long time, so that flexibility as well as waterproofness can be secured.

In addition, PEBAX (Polyether-block-amide) has a small change in hardness even at low temperatures, has excellent fatigue resistance, increases deformation restraint while maintaining buffering properties, and has excellent molding processability due to its small specific gravity, low hygroscopicity, and bending resistance. Increases fatigue resistance, weather resistance, flexibility, creep resistance, and adhesion.

In addition, triphenylphosphine enhances weather resistance and enhances water pressure resistance and waterproofness through surface homogenization, and increases adhesion.

In addition, CZ (N-cyclohexybenzothiazole-2-sulfenamide) is to increase the antifouling function. And, sodium xylenesulfonate is added to increase adhesion stability and prevent fluffing. In addition, 2-phenylimidazole is added to reduce the drying shrinkage rate to prevent deformation of the gel-like sheet and to maintain a smooth surface in a smooth state to increase the ability to inhibit adhesion of foreign substances.

Furthermore, polytetrafluoroethylene is a polyfron PTFE-D (Dispersion) having a structural formula (-CF2-CF2-)n, and increases durability and adhesion because it increases lubricity as well as heat resistance. Lastly, silicone resin increases adhesion, fixation, and adhesion, and enhances stain resistance and water pressure resistance.

On the other hand, the base housing 53 has an empty interior, and a hole is formed in the protrusion 54 so that the locking hole 59 is retractable and retractable.

At this time, the locking hole 59 is a locking block (59a) that slides inside the base housing 53, and protrudes from one side of the locking block (59a) and is formed on one side of the outer surface of the insertion piece (57). A locking hook 59b caught in the locking groove 57a, a spring bar 59c protruding on the opposite side of the locking hook 59b, and the spring bar 59c fitted to the inner wall of the base housing 53 A coil spring 59d for elastically supporting the locking block 59a, and an operating bar 59e protruding from the upper surface of the locking block 59a and exposed through one side of the base housing 53 include

Thus, when the insertion piece 57 is inserted into the fixing pin 56, the locking hook 59b is caught in the locking groove 57a and is fixed so that the insertion piece 57 is not separated, and when you want to separate it, the operation bar ( 59e) is removed, the coil spring 59d is compressed and the locking hook 59b comes out of the locking groove 57a, so that the insertion piece 57 can be separated.

In this way, it can be easily assembled, fixed, separated, disassembled, so it is convenient to install and use, and there is an advantage that it can be freely installed in a vulnerable area such as inside an elevator to monitor a fire.

In addition, in the present invention, as illustrated in FIG. 7 , the satellite antenna 70 controlled by the controller 13 is connected to the shelter electronic lock 400 .

A plurality of the satellite antennas 70 are installed at intervals on the wall of each wing of the apartment house.

In addition, the Wi-Fi module 14 is mounted on the support of the satellite antenna 70, and includes a radiation antenna.

Thus, when an emergency situation occurs and a specific signal is received from the management server 300, the controller 13 turns on the Wi-Fi module 14, and through the signal received from the satellite antenna 70, within a certain radius, freely through the mobile phone By enabling communication, safety is strengthened by preventing residents from losing communication in an emergency when wireless communication base stations cannot be used due to natural disasters such as fire, earthquake, heavy rain, etc.

In particular, the satellite antenna according to the present invention receives a low-orbit satellite signal and converts it to be connectable to the Internet network through a gateway, and is usually used in a shaded area or vulnerable area of the Internet.

In the present invention, such a satellite antenna is used to allow residents within a certain radius to freely use the Wi-Fi network through the Wi-Fi module 14. Above all, in order to increase the satellite signal reception sensitivity, that is, to increase the antenna gain, the satellite antenna (70) is configured to have a special structure.

Although the satellite antenna 70 according to the present invention is a general dish-shaped antenna, it is characterized in that a plurality of leakage slots 73 are formed on its surface.

In other words, a leaky slot array antenna is implemented.

The leakage slot 73 allows the main beam to be scanned by changing the phase constant, thereby obtaining a higher antenna gain.

Here, in order to change the phase constant, the present invention specifies the tube wall of the leakage slot (73).

For example, when the interval of the leakage slots 73 is periodically arranged as s, the main beam direction θ of the satellite antenna is,

로 주어지고,

is given as

The correct main beam direction θ according to the arrangement theory is,

가 되게 된다.

will become

Therefore, if s is adjusted so that a grating lobe does not appear, it is possible to increase the antenna gain.

Here, λ is the wavelength of radio waves in free space, and λ _s is the wavelength of radio waves within the antenna body, that is, the wavelength of radio waves moving along the transmission line 72 .

Accordingly, in order to obtain the maximum antenna gain, a dielectric reflective wall 74 is built in front of the leakage slot 73, the width of the leakage slot 73 is 0.5-0.8 mm, and the interval s between the leakage slots 73 is 3.0. -3.4mm is maintained, and the reflective wall 74 is preferably formed vertically to a height of 1.3-1.5mm.

In addition, the leakage slot 73 must be communicated with the transmission line 72 of course, and the dielectric for making the reflective wall 74 may be made of the same material as the antenna body 71, preferably, an epoxy resin.

In this way, it is possible to obtain the maximum antenna gain within the range where the grating lobe does not appear, thereby maximizing the satellite signal reception efficiency.
