Description

Technology Field

[0001] The present invention relates to a fire safety management system for multi-unit residential buildings, and more specifically, to an improved fire safety management system for multi-unit residential buildings that utilizes an IoT server based on the Internet of Things to increase the accuracy of monitoring and managing fires occurring within households in multi-unit residential buildings, establishes a management system to prevent the loss of fire equipment stored in fire equipment cabinets so that it can be utilized as an immediately available asset in the event of an actual fire, and also buries fire extinguishing pipes on all four sides of load-bearing columns provided in underground parking lots for constant inspection, and sprays water in the event of a fire to protect firefighters from flames when they enter, thereby increasing the effectiveness of fire suppression. Background Technology

[0002] The Internet of Things (IoT) is based on the idea that everyday objects, rather than computers and computer networks, are readable, recognizable, localizable, addressable, and controllable through IoT communication networks (e.g., ad-hoc systems or the Internet).

[0003] In other words, the Internet of Things (IoT) is a new information and communication infrastructure that connects existing objects to the internet, enabling humans and objects, and objects and objects, to communicate with each other anytime and anywhere.

[0004] Meanwhile, fire safety management systems installed in multi-unit dwellings are limited to generating alarm sounds. In other words, they only sound an alarm and lack the capability to extinguish a fire.

[0005] Furthermore, in the event of a fire, people may attempt to board the elevator out of urgency; however, since a power outage immediately causes a safety accident, boarding itself must be blocked, yet such measures are not provided. Additionally, there is a need to resolve the problem where evacuation becomes difficult and safety accidents occur if smoke and high temperatures fill the stair landing, even though people must evacuate via it.

[0006] In particular, in the case of fire hydrants, since it is impossible for the general public to open them and supply water while evacuating in an emergency, they are, in a sense, virtually useless.

[0007] It is intended for use by firefighters upon arrival, but it is practically difficult for the general public to utilize it for initial firefighting.

[0008] Furthermore, firefighting equipment stored in firefighting cabinets—such as fire extinguishers, hand axes, lanterns, gas masks, medical kits, fire suits, fire gloves, and fire boots—is easily lost and poorly managed, leading to a limitation where it becomes completely unusable in the event of an actual fire.

[0009] In addition, the recent trend is that most multi-unit buildings are converting the ground level into parks, so parking lots are all being located underground.

[0010] Therefore, it is difficult for fire trucks to enter in the event of a fire, and even when firefighters attempt to enter, they cannot easily do so because flames rise within the enclosed space, which could potentially lead to casualties.

[0011] Therefore, measures to resolve these problems must also be sought. Prior art literature

Specific details for implementing the invention

[0021] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0022] Prior to a detailed description of the present invention, the present invention is a technology improved using the configuration of Registered Patent No. 10-2369691, and parts of the configuration will be cited as is.

[0023] That is, the system according to the present invention includes a plurality of fire detectors (100) installed in each household of a multi-unit building as shown in the example of FIG. 1, a fire alarm (200) installed outdoors, a fire equipment box (300) provided on the stairs of each floor of the multi-unit building, and an IoT server (ISV) installed in a management room that is wired to the fire detectors (100), the fire alarm (200), and the fire equipment box (300) to monitor and control the fire situation of the multi-unit building and to constantly check whether the fire equipment box (300) is open.

[0024] Here, IoT (Internet of Things) refers to the Internet of Things.

[0025] In addition, the IoT server (ISV) is a server equipped with artificial intelligence (AI) capabilities, and in particular, it has the feature of immediately determining whether there is a fire by learning feature points of an image using a known deep learning technique.

[0026] And, the fire detector (100) and the fire alarm (200) both have a unique identification number, and this unique identification number is identified by the IoT server (ISV).

[0027] To this end, the fire detector (100) and fire alarm (200) are controlled to transmit their own unique identification number together when outputting a detection signal.

[0028] Therefore, when a fire occurs, the IoT server (ISV) can immediately determine where in the apartment building the fire has occurred, so it can control the alarms to sound only in the vicinity of that location.

[0029] The reason for doing this is to avoid exacerbating confusion by sending unnecessary alarms to residents of distant apartment buildings where no fire has occurred, and also to prevent casualties resulting from large-scale evacuations.

[0030] In addition, the fire fighting equipment box (300) is configured so that the IoT server (ISV) can detect the opening and closing of the door.

[0031] To this end, the fire fighting equipment box (300) includes a controller (310), which is a type of microprocessor that communicates with the IoT server (ISV), as shown in the example of FIG. 2, a limit switch (320) connected to the controller (310) and detecting the opening and closing of the equipment box door, and a plurality of detection sensors (330) installed on a tray provided inside the fire fighting equipment box (300) to detect whether the fire fighting equipment stored in the tray is attached or detached.

[0032] At this time, the controller (310) checks whether the mechanism door is open or closed according to the on / off state of the limit switch (320), and when it is open, transmits a signal to the IoT server (ISV) indicating that it is open.

[0033] In this case, a surveillance camera (CMR) may be additionally installed on one side wall of the stairs where the fire extinguisher box (300) is positioned at a distance from the fire extinguisher box (300), and the surveillance camera (CMR) is registered with an IoT server (ISV) with a unique number assigned to it and is electrically connected to the controller (310) so that when the fire extinguisher box door is opened, it immediately photographs the fire extinguisher box door side according to the control signal of the controller (310) and transmits the photographic information to the IoT server (ISV).

[0034] In addition, the controller (310) and the surveillance camera (CMR) can use commercial power.

[0035] Then, the IoT server (ISV) analyzes the video using deep learning techniques to determine whether it is unauthorized opening, forced damage, or opening by an authorized person (using a door key), and controls the system to issue an alarm in the case of unauthorized opening or forced damage.

[0036] To this end, an alarm (ARM) registered with an IoT server (ISV) and assigned a unique number is installed next to the aforementioned surveillance camera (CMR) and is directly controlled.

[0037] In addition, the detection sensor (330) includes a first proximity sensor (331) for detecting the detachment of a fire extinguisher, a second proximity sensor (332) for detecting the detachment of a hand axe, a third proximity sensor (333) for detecting the detachment of a lantern, a fourth proximity sensor (334) for detecting the detachment of a gas mask, a fifth proximity sensor (335) for detecting the detachment of a medical box, a sixth proximity sensor (336) for detecting the detachment of a fireproof suit, a seventh proximity sensor (337) for detecting the detachment of fireproof gloves, and an eighth proximity sensor (338) for detecting the detachment of fireproof boots.

[0038] In addition, these first, second, third, fourth, fifth, sixth, seventh, and eighth proximity sensors (331, 332, 333, 334, 335, 336, 337, 338) are each connected to the controller (310) with a unique number assigned to each, so the controller (310) checks which sensor sent the signal and transmits to the IoT server (ISV) that the item is lost, thereby allowing the IoT server (ISV) to verify the lost item in real time without having to go to the site, thus increasing management convenience.

[0039] Additionally, a square slit (410) of a certain width is formed on each side of the column (400) provided in the underground parking lot of the above-mentioned multi-unit building.

[0040] And, a square tube (420) is embedded in the square slit (410), and a plurality of spray nozzles (600) are installed in the square tube (420). Additionally, the square tube (420) is connected to a fire extinguishing water branch pipe (520) branched from the fire extinguishing water pipe (530), and a solenoid valve (522) is installed in the fire extinguishing water branch pipe (520), and the solenoid valve (522) is connected to and controlled by the IoT server (ISV).

[0041] In particular, a fire detector (100) with a unique number assigned is installed on the ceiling surface of each column (400) so that the IoT server (ISV) can easily identify the point of origin of the fire, and it is preferable to configure it so that fire extinguishing water is discharged only from the column (400) at the point of origin by opening a solenoid valve (522) on a pipe connected to the column (400) at the point of origin that is managed with a unique number assigned based on that information.

[0042] At this time, in order to fix the square tube (420), a plurality of fixing grooves (412) are formed indented around the square slit (410) of the column (400), and an insertion groove (422) is formed indented on the front surface of the square tube (420) at a position corresponding to the fixing grooves (412).

[0043] Here, the length of the square pipe (420) is formed to be shorter than the length of the square slit (410). This is because there must be sufficient space to connect the fire extinguishing water pipe (520), etc.

[0044] And, a fixing plate (430) is fitted into the insertion groove (422) and the fixing groove (412), and in that state, the anchor bolt (432) firmly fixes the fixing plate (430) to the column (400), thereby allowing the square tube (420) to be tightly fixed.

[0045] In addition, the square tube (420) is a hollow tube body as shown in the examples of FIGS. 3 and 4, and a connector (422) protrudes from the upper surface, and a fixed hook ring (424) is formed in the form of a double tube around the connector (422), and an O-ring (426) is interposed between the connector (422) and the fixed hook ring (424).

[0046] Additionally, a connection connector (500) is connected to the connection port (422), the connection port (422) is fitted into the inner diameter of the connection connector (500), the tip of the connection connector (500) is sealed by pressing an O-ring (426), and a binding hook (510) is formed on the outer circumference of the connection connector (500) to which the fixing hook ring (424) is hook-fixed.

[0047] Therefore, by simply pushing the above connection port (500) into the above connection port (422), the connection can be automatically, easily, and quickly established.

[0048] In addition, a fire extinguishing water distribution pipe (520) is connected to the above connection port (500), and the fire extinguishing water distribution pipe (520) branches off from the fire extinguishing water pipe (530), and the fire extinguishing water pipe (530) is piped while fixed to the ceiling surface of the underground parking lot, and a solenoid valve (522) is installed on the fire extinguishing water distribution pipe (520) to automatically control the supply of fire extinguishing water.

[0049] Meanwhile, a plurality of spray nozzles (600) of the shape shown in Fig. 5 are assembled on the front of the square tube (420).

[0050] The above spray nozzle (600) comprises a nozzle body (610) having a screw fastening part (612) that is screw-fastened to the front of a square tube (420) for uniform spraying of fire extinguishing water, a water dispersion plate (620) having an inner screw fastening part (622) that is screw-coupled to the inner diameter of the screw fastening part (612) and a water outflow hole (624), and a cover body (630) that is screw-fastened to the nozzle body (610) so that the water dispersion plate (620) is embedded therein and has a plurality of spray holes (632) formed radially.

[0051] At this time, the water dispersion plate (620) is a means for guiding the extinguishing water collected inside the cover body (630) to be sprayed through the spray hole (632) with uniform pressure by ejecting the incoming extinguishing water in the reverse direction through the water outlet hole (624) in the form of a disc with curvature.

[0052] If the water dispersion plate (620) is not present, high-pressure rapid-fire water (a stream of water shot quickly) is ejected through the central spray hole (632) facing the place where the fire extinguishing water flows in, but low-pressure slow-fire water (a stream of water shot slowly) is ejected through the spray hole on the perimeter surface, making it difficult to achieve uniform spraying, so this is intended to prevent that.

[0053] In particular, since the reason for installing the square tube (420) of the present invention is to protect firefighters entering while engulfed in flames, it helps in suppressing the fire, but the most important purpose is to protect the firefighters, so uniform spraying is required.

[0054] In addition, in the present invention, the square tube (420) and the spray nozzle (600) are spray-coated with an anti-erosion agent.

[0055] At this time, the anti-erosion agent is composed by mixing 10 parts by weight of mesophase pitch, 5.5 parts by weight of pyromellitic dianhydride, 5.5 parts by weight of zinc powder, 5 parts by weight of petrolatum, 5 parts by weight of glutaryl concentrate, 5 parts by weight of phosphite, and 5.5 parts by weight of sodium borohydride, based on 100 parts by weight of polycarbonate resin.

[0056] Here, it is a base resin that firmly maintains the durability, corrosion resistance, and adhesion of the polycarbonate resin.

[0057] In addition, the mesophase pitch enhances corrosion resistance by increasing its bonding with zinc powder through a molten liquid pitch phase and changing into a solid carbon phase. In particular, the mesophase pitch can be manufactured from petroleum-based heavy oil or coal-based tar, or synthesized from other organic materials.

[0058] In addition, pyromellitic dianhydride is a substance corresponding to CAS number 89-32-7, which enhances slip properties to increase antifouling properties and increases corrosion resistance.

[0059] In addition, zinc powder is an inorganic material that significantly increases corrosion resistance and salt resistance through combination with mesophase pitch.

[0060] In addition, petrolatum enhances corrosion resistance and strength characteristics, while glutaryl concentrate, phosphite, and sodium borohydride block even the formation of microbubbles and strengthen bonding and fixation stability during molding, thereby contributing to the realization of corrosion resistance and high strength.
