[0012] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0013] Prior to the explanation, the present invention adopts the configuration of Registered Patent No. 10-2488378 as is. Therefore, some configurations in the following description will be cited verbatim from the content of the aforementioned registered patent, and the improved parts will be described in a supplementary manner.

[0014] Before explaining the method of operating the fire extinguishing device for an underground parking lot of a multi-unit building according to the present invention, the fire extinguishing device is first described.

[0015] A firefighting device to which the operation method according to the present invention is applied comprises, as illustrated in the examples of FIGS. 1 to 3, a fire detector (1) installed to move along the ceiling of an underground parking lot of a multi-unit dwelling, a CCD camera (100) mounted on the fire detector (1), an alarm (110) mounted on the CCD camera (100), a heat detector (120) mounted on the CCD camera (100), a smoke detector (130) mounted on the CCD camera (100), a controller (102) mounted on the CCD camera (100) and having a built-in memory, a wireless communicator (104) mounted on the CCD camera (100) and controlled by the controller (102), a repeater (2) installed on the ground at the location of the underground parking lot to communicate with the wireless communicator (104), and an image received from the repeater (2) is read using a deep learning technique to check for the presence of fire, and when it is determined that a fire has occurred, the It includes a management server (400) provided in the management office to transmit a control signal to the controller (102) so that an alarm can be given through the alarm (110).

[0016] At this time, the management server (400) is equipped with an image reading unit and uses artificial intelligence based on deep learning techniques to continuously accumulate and learn image data regarding flames (size, temperature by color, etc.), and based on the learned content, makes a comparative judgment to quickly determine whether or not a fire has occurred.

[0017] The image analysis unit of this management server (400) has a deep learning-based artificial intelligence that learns more as the accuracy and reliability of its recognition of fire situations in the building increase, so ultimately, early fire detection and alarm can be performed unmanned without a separate manager.

[0018] For example, the deep learning-based artificial intelligence being performed can operate by learning images of flames or smoke, storing a large amount of flame and smoke images in a database, and the deep learning-based artificial intelligence of the image reading unit can improve its ability to recognize flames and smoke through the flame and smoke images stored in this database.

[0019] And, the above CCD camera (100) is a miniature and is installed at the center of the front end surface of the cylindrical main body housing (10).

[0020] In addition, clamps (12) capable of being fixed to a fire detector (1) are provided on both sides of the rear end of the main body housing (10). In some cases, these clamps may not be provided, and the main body housing (10) may be fixed directly to the fire detector (1) by being inserted and fixed.

[0021] In addition, a controller (102) is mounted inside the main body housing (10), and a wireless communication device (104) is connected to the controller (102). Each controller (102) is assigned a unique number, so that when communicating with the management server (400), the management server (400) can know where the controller (102) is located.

[0022] This is configured so that location information regarding which fire detector (1) is installed for each unique number of the controller (102) is entered into the database of the management server (400) in advance, thereby enabling immediate verification.

[0023] In addition, alarms (110) are installed on both sides of the perimeter of the main body housing (10) and are connected to and controlled by the controller (102).

[0024] In addition, a heat detector (120) and a smoke detector (130) are installed on each side of the CCD camera (100) and are connected to and controlled by a controller (102).

[0025] In addition, since the above CCD camera (100), heat detector (120), smoke detector (130), and controller (102) are installed in the fire detector (1), they use commercial power supplied to the underground parking lot as a power source by adapting it.

[0026] In this way, if a CCD camera (100) is installed in all fire detectors (1) of a multi-unit dwelling, it is possible to detect all fires that may occur outside the unit in real time, and if a fire is confirmed, an immediate warning can be issued, thereby contributing to the initial suppression of the fire.

[0027] Meanwhile, the fire detector (1) is configured to move periodically along a plurality of racks (310) installed in the ceiling of the underground parking lot in accordance with the volume of the underground parking lot, as shown in the example of FIG. 3.

[0028] At this time, the rack (310) is fixed across a plurality of suppressor (500) pipes, and the fire detector (1) is equipped with a CCD camera (100) having a wide shooting radius and is configured to slide by having a pinion (340) driven by a motor (330) and engaged with the rack (310).

[0029] In addition, the fire detector (1) is further provided with a touch bar (350) that contacts the fire suppressor (500), and since the number of fire suppressors (500) included in one rack (310) is fixed, when driven by the relay control unit (3) provided in the relay (2), the relay control unit (3) recognizes how many fire suppressors (500) have passed from the home position, thereby allowing the position to be known when periodically reciprocating.

[0030] At this time, the rack (310) is formed on the lower surface of a rack plate (312) in the shape of a 'T', and sliding surfaces (314) are formed on the upper surfaces of both sides of the rack plate (312) so that the fire detector (1) can move smoothly along the sliding surfaces (314) while suspended from the rack plate (312), and the method of fixing to the fire suppressor (500) is fixed with a ∩-shaped bolt (316) so as not to interfere with the sliding of the fire detector (1).

[0031] In addition, each of the above fire detectors (1) is assigned a unique code and configured to be recognized by the relay control unit (3), so the relay control unit (3) can accurately control the location of the fire detectors (1) installed in rows and columns.

[0032] And, when a fire is detected, the relay control unit (3) clearly recognizes the location, so the information is transmitted to the management server (400) through the relay (2) and used as data for fire suppression.

[0033] On the other hand, the above suppressor (500) is driven and controlled by a suppression controller (5) installed together with a relay (2).

[0034] At this time, the above-mentioned suppressor (500) is installed at regular intervals in the longitudinal direction so as to receive fire extinguishing water through a fire extinguishing resin pipe (P, see FIG. 4) branched from a fire extinguishing supply pipe (not shown) piped parallel to the rack (310), and as shown in the example of FIG. 4, it comprises a fixed body (510) connected and fixed to the fire extinguishing resin pipe (P), a movable body (520) rotatably assembled at the bottom of the fixed body (510) with a bearing (512) interposed therein, a bracket (530) fixed to the outside of the movable body (520), a driving gear (540) meshing with a gear formed on the upper outer surface of the bracket (530), a rotary motor (550) that rotates the driving gear (540), and a unique number assigned to control the rotation angle of the rotary motor (550) according to a control signal of the suppression controller (5). It includes a motor controller (560) equipped in a rotary motor (550).

[0035] Here, the rotary motor (550) is driven to reciprocate the fluid body (520) within a range of 180°.

[0036] That is, after detecting the origin of the fire, the fire suppressor (500) located closest to the origin is controlled to direct the spraying direction toward the origin, thereby concentrating the spraying of fire extinguishing water to enhance the initial suppression effect.

[0037] In the case of conventional sprinklers, fire extinguishing water is sprayed radially, resulting in a significant amount of water being sprayed in directions unrelated to the origin, which is highly inefficient.

[0038] Therefore, the focus of the present invention is on increasing the initial suppression effect by concentrating the spraying of extinguishing water toward the origin of the fire.

[0039] To this end, a sealing material (521) is configured to protrude radially from the top of the movable body (520) and be inserted into a part of the inner diameter of the fixed body (510).

[0040] Thus, it is configured to prevent leakage through the bearing joint when fire extinguishing water is supplied, and to allow for smooth, concentrated downward transport and spraying.

[0041] Additionally, an impeller motor (522) is mounted in the inner diameter of the above-mentioned fluid body (520), and is sealed with a waterproof seal (523) to increase watertightness, and fire extinguishing water passages (524) are formed at intervals on both sides of the impeller motor (522), and ribs (525) are formed intermittently in the fire extinguishing water passages (524) to fix the inner part where the impeller motor (522) is mounted.

[0042] In addition, an impeller (526) is mounted on the motor shaft of the impeller motor (522), and a semicircular discharge guide (527) is installed on a part of the circumference of the impeller (526) so that the fire extinguishing water discharged by the impeller (526) can be concentrated and sprayed in only one direction.

[0043] In addition, an impeller controller (528) is installed on one side of the above-mentioned fluid body (520) and connected via a lead wire that passes through the above-mentioned rib (525). The impeller controller (528) is electrically connected to the suppression controller (5) and installed to be driven and controlled. To this end, the impeller controller (528) is also assigned a unique number so that it can be easily and accurately controlled.

[0044] In particular, unlike conventional simple rotary cutting type sprinklers, the fire extinguishing water spraying method using an impeller (526) can rapidly concentrate water in a specific direction while rotating at high speed, so the fire suppression effect increases rapidly.

[0045] On the other hand, a smoke control unit (6) is installed in conjunction with the above relay unit (2), and the smoke control unit (6) is electrically connected to a management server (400).

[0046] At this time, the smoke control unit (6) also has the advantage of being assigned a unique number and can be directly controlled individually through the management server (400).

[0047] And, a smoke exhaust duct (610) is installed parallel to the rack (310) on the ceiling surface of the underground parking lot, and an internal smoke exhaust fan (600) is installed in a plurality of branch ducts branched from the smoke exhaust duct (610) at a position and number corresponding to the suppressor (500), and an external smoke exhaust fan (620) is installed outside the underground parking lot for each smoke exhaust duct (610) to which the internal smoke exhaust fan (600) is connected, and the internal smoke exhaust fan (600) and the external smoke exhaust fan (620) are each configured to be connected to and controlled by a smoke exhaust controller (6).

[0048] The method of operating the fire extinguishing device according to the present invention, which is configured as such, is as follows.

[0049] First, a first step is performed in which a fire detector (1) periodically moves within a defined area of ​​the underground parking lot to detect a fire.

[0050] The first step above involves the fire detector (1) moving periodically to detect according to a control signal from the management server (400), and the management server (400) recognizes the location of the fire detector (1) in real time based on the distance traveled during detection.

[0051] This is because the unique number assigned to each suppressor (500) is known, so when moving to a location, the location is recognized when passing through the corresponding suppressor (500).

[0052] Afterwards, when the fire detector (1) detects the occurrence of a fire, the management server (400) performs a second step of identifying the origin of the fire by checking the current location of the fire detector (1).

[0053] That is, the second step above is a step in which the movement of the fire detector (1) stops the moment the fire detector (1) detects a fire, and the location is recognized as the origin of the fire.

[0054] Next, after the second stage, the management server (400) performs a third stage in which it operates the internal smoke exhaust fan (600) and the external smoke exhaust fan (620) arranged on both sides centered on the origin of the fire to discharge smoke around the origin to the outside.

[0055] In this case, it is desirable to operate other smoke exhaust fans while the above third step is in progress to prevent smoke from spreading throughout the entire underground parking lot.

[0056] In addition, the management server (400) controls the motor controller (560) of the suppression device (500) closest to the location of the fire detector (1) to drive the rotary motor (550) so that the direction of discharge of fire extinguishing water through the impeller (526) is directed toward the origin of the fire, thereby performing a fourth step of rotating the fluid body (520) constituting the suppression device (500).

[0057] In this way, it becomes possible to spray concentrated firefighting water towards the origin of the fire.

[0058] In addition, the management server (400) may further perform the step of rotating and positioning the opposite fire suppressor, which is located between the currently rotating fire suppressor (500) and the fire detector (1), toward the origin of the fire.

[0059] By doing this, intensive spraying of fire extinguishing water is possible from both sides, which can double the fire suppression effect.

[0060] Afterwards, as the impeller (526) rotates, fire extinguishing water is supplied, and a fifth stage is performed in which fire suppression operation occurs through concentrated spraying of fire extinguishing water.

[0061] Next, when the fire is extinguished, the sixth step of returning the fire suppression device (500), including the fire detector (1), to the home position is performed, thereby ending the method of operating the fire extinguishing device.

[0062] In this way, the present invention enhances the monitoring function for fires occurring in underground parking lots of multi-unit housing, and when a fire occurs, not only quickly locates the source of the fire and discharges smoke generated around the source to the outside, but also manages and controls the fire to allow firefighting equipment to immediately suppress the fire towards the source, thereby preventing the fire from spreading significantly into a secondary fire.
