Description

[Technical Field]

[0001] The present invention relates to a fire suppression system that automatically tracks the location of an ignition, and more specifically, to a fire suppression system that automatically tracks the location of an ignition while detecting in real time whether or not a fire has occurred in a monitored area, and can extinguish the fire by spraying a fire extinguishing agent. [Background technology]

[0002] Generally, most facilities, buildings, and other structures are equipped with fire suppression devices such as sprinklers and fire shutters to quickly respond to fires and protect property and human lives.

[0003] In sprinklers such as those described above, the soluble metal in the head melts due to the abnormally high temperature caused by a fire, and then the sprinklers automatically spray fire-extinguishing water to extinguish the fire.However, in the early stages of a fire, the abnormally high temperature caused by the fire is not transmitted to the sprinklers installed on the ceiling of the room, making it impossible to extinguish the fire.Not only that, by the time the sprinklers spray fire-extinguishing water, the fire has already progressed for a considerable amount of time, and the fire is extinguished when the damage caused by the fire is already very great.

[0004] As a result, in recent years, smart fire suppression devices have been introduced that automatically detect fires, spray water or fire-extinguishing liquid, and continue to operate until the fire is extinguished. However, these fire suppression devices only disclose technology for detecting the occurrence of a fire, detecting the fire area, and controlling the fire extinguishing unit to spray fire-extinguishing water into the fire area. There is no suggestion of a method for accurately determining whether or not a fire detected by the fire detection unit is actually a fire, tracking the point of ignition, and spraying fire-extinguishing liquid at the point of ignition in the early stages of the fire, thereby quickly extinguishing the fire.

[0005] [Patent Document 1] Republic of Korea Patent Publication No. 10-2236901 (March 31, 2021) Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide a fire suppression system that automatically tracks the ignition point, which can extinguish a fire that has broken out in the monitored area in the shortest possible time by detecting and tracking the occurrence of a fire within the monitored area in real time and accurately aiming and spraying a fire extinguishing agent at the ignition point in the early stages of the fire.

[0007] Other detailed objects of the present invention can be clearly understood by experts and researchers in this technical field from the specific content described below. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a fire suppression system that automatically tracks the point of ignition, including: a fire extinguishing agent injection module whose casing is installed within the monitored area so that it can rotate horizontally, and a waterproof nozzle that can spray fire extinguishing agent at the point of fire within the monitored area so that it can rotate vertically on the casing; an automatic fire point tracking detection module that is arranged close to the waterproof nozzle and detects whether a fire has occurred within the monitored area and calculates the coordinates of the ignition point; and a control unit that rotates the casing of the fire extinguishing agent injection module and the waterproof nozzle based on the coordinates of the ignition point calculated by the automatic fire point tracking detection module, aims the waterproof nozzle at the point of ignition, and then sprays fire extinguishing agent at the point of ignition.

[0009] For example, the extinguishant injection module may include: a casing installed in the monitored area so as to be rotatable horizontally by a first drive motor operated by the control unit; a waterproof nozzle installed in the casing so as to be rotatable vertically by a second drive motor operated by the control unit and for spraying the extinguishant; an extinguishant storage tank connected to the waterproof nozzle via an extinguishant supply line and for supplying the extinguishant stored therein to the waterproof nozzle via the extinguishant supply line; and an on-off valve installed on the extinguishant supply line so as to be opened by the control unit when a fire occurrence signal is transmitted from the fire point automatic tracking detection module to the control unit, so that the extinguishant stored in the extinguishant storage tank can be sprayed to the fire point via the extinguishant supply line and the waterproof nozzle.

[0010] For example, the automatic fire point tracking detection module may include an ultraviolet detection sensor arranged in close proximity to the waterproof nozzle, which detects ultraviolet rays emitted from a fire source in the monitored area and transmits a fire detection signal to a control unit; first and second infrared detection sensors which, when the fire detection signal is transmitted from the ultraviolet detection sensor to the control unit, detect infrared rays emitted from the fire source to perform dual detection of whether or not a fire has occurred and detect the infrared detection position; an ignition point coordinate calculation unit which calculates the coordinates of the ignition point based on the infrared detection positions detected by the first and second infrared detection sensors and transmits them to the control unit, and rotates the casing and the waterproof nozzle to correspond to the coordinates of the ignition point so that the waterproof nozzle can be aimed at the ignition point; and a thermal imaging camera arranged in close proximity to the waterproof nozzle, which can detect whether or not a fire has occurred in the monitored area by acquiring a thermal image of the monitored area and measuring the temperature.

[0011] Here, the thermal imaging camera acquires a thermal image of the ignition point when the casing of the extinguishing agent injection module and the waterproof nozzle rotate based on the coordinates of the ignition point detected by the first and second infrared detection sensors and the waterproof nozzle is aimed at the ignition point, and determines that there is an actual fire only when the temperature of the ignition point is detected to be above a critical temperature, and transmits a signal to emit the extinguishing agent to the control unit.

[0012] Meanwhile, when an ignition point is detected that is above the critical temperature in the thermal image video acquired in the monitoring area while no fire is detected by the ultraviolet detection sensor and the first and second infrared detection sensors, the thermal imaging camera calculates the coordinates of the ignition point and transmits them to the control unit, rotates the casing and the waterproof nozzle to correspond to the coordinates of the ignition point, aims the waterproof nozzle at the ignition point, and then sprays the fire extinguishing agent at the ignition point through the waterproof nozzle.

[0013] In addition, the automatic fire tracking and detection module may further include an AI camera that is placed close to the waterproof nozzle and can acquire images within the monitored area and detect whether or not a fire has occurred in the monitored area using actual images.

[0014] Here, when an ignition point detected as exceeding a critical temperature is detected by the thermal image video acquired by the thermal imaging camera in the monitoring area while no fire is detected by the ultraviolet detection sensor and the first and second infrared detection sensors, the AI camera acquires an actual image video of the ignition point and determines whether or not there is an actual fire. If it determines that there is an actual fire, it calculates the coordinates of the ignition point and transmits them to the control unit. When the coordinates of the ignition point are transmitted from the AI camera, the control unit activates the ultraviolet detection sensor and the first and second infrared detection sensors to re-detect whether or not there is a fire at the ignition point. The infrared detection position detected by the operation of the first and second infrared detection sensors is transmitted to the ignition point coordinate calculation unit, which recalculates the coordinates of the ignition point and transmits them to the control unit. The control unit then rotates the casing and the waterproof nozzle to correspond to the recalculated coordinates of the ignition point, aims the waterproof nozzle at the ignition point, and the thermal imaging camera further acquires a thermal image of the monitored area to remeasure the temperature of the ignition point. Only when the temperature of the ignition point is detected to be above the critical temperature, is it determined to be an actual fire and a fire extinguishing agent discharge signal is transmitted to the control unit so that the fire extinguishing agent can be discharged at the ignition point.

[0015] In addition, when a fire is detected by an actual image acquired in the monitoring area while no fire is detected by the ultraviolet detection sensor, the first and second infrared detection sensors, and the thermal imaging camera, the AI camera analyzes the actual image of the ignition point to determine whether or not there is an actual fire, and when it determines that there is an actual fire, calculates the coordinates of the ignition point and transmits them to the control unit. When the control unit receives the coordinates of the ignition point from the AI camera, it activates the ultraviolet detection sensor and the first and second infrared detection sensors to re-detect whether or not there is an occurrence of a fire at the ignition point, and The infrared detection position detected by the operation of the infrared detection sensor is transmitted to the ignition point coordinate calculation unit, which calculates the coordinates of the ignition point and transmits them to the control unit.The control unit then rotates the casing and the waterproof nozzle to correspond to the coordinates of the ignition point that have been re-detected by the control unit, aims the waterproof nozzle at the ignition point, and further obtains a thermal image of the monitoring area using the thermal imaging camera to re-measure the temperature of the ignition point.Only when the temperature of the ignition point is detected to be above the critical temperature, it is determined to be an actual fire, and a fire extinguishing agent discharge signal is transmitted to the control unit so that the fire extinguishing agent can be discharged at the ignition point.

[0016] On the other hand, when the control unit determines that the ignition point is located within a set distance from the waterproof nozzle, it controls the waterproof nozzle to spray extinguishing agent at the ignition point, and when it determines that the ignition point is beyond the set distance, it controls the waterproof nozzle to spray extinguishing agent directly at the ignition point.

[0017] In addition, the automatic fire tracking detection module may further include a dust prevention means that operates periodically at intervals set by the control unit and removes dust accumulated on the surfaces of the ultraviolet detection sensor and the first and second infrared detection sensors, and on the surfaces of the thermal imaging camera and AI camera lens. [Effects of the Invention]

[0018] As described above, the fire suppression system for automatically tracking ignition points according to one embodiment of the present invention detects whether or not a fire has occurred in a monitored area in real time through the automatic fire point tracking detection module, tracks the ignition point, and very quickly and accurately determines whether or not a fire has actually occurred at the detected ignition point. Then, it accurately aims and sprays a fire extinguishing agent at the ignition point, thereby quickly suppressing the fire in an early stage.

[0019] In addition, the fire suppression system for automatically tracking the ignition point according to one embodiment of the present invention is capable of detecting the presence or absence of a fire in the monitored area in multiple overlapping manners in response to various initial fire occurrence conditions. Therefore, even in the early stages of a fire when it is difficult to detect the presence or absence of a fire, the system can quickly and accurately detect and track the ignition point, and if it determines that a fire has actually occurred, it can aim a waterproof nozzle at the ignition point and spray a fire extinguishing agent, thereby quickly suppressing the fire in the early stages of the fire.

[0020] Therefore, the fire suppression system for automatically tracking the ignition point according to one embodiment of the present invention can not only very quickly and accurately detect whether or not there is an actual fire within the monitored area at an early stage of the fire, but also track the ignition point in real time, and if it determines that there is an actual fire, it can suppress the fire at the ignition point within the shortest time possible. This prevents a fire that has started within the detected area from spreading into a large-scale fire, thereby significantly improving the reliability and safety of fire detection and fire suppression, and minimizing the loss of life and damage to property due to the start of a fire and its suppression.

[0021] In addition, the advantages of the present invention can be clearly grasped and understood by experts and researchers in this technical field from the specific content described below or during the process of implementing the present invention. [Brief explanation of the drawings]

[0028] Preferred embodiments of the present invention will now be described in more detail with reference to the drawings.

[0029] FIG. 1 is a diagram showing an installation state of a fire suppression system for automatically tracking ignition points according to one embodiment of the present invention, FIG. 2 is a diagram showing an installation state of an automatic ignition point tracking detection module in a fire extinguishing agent injection module, and FIG. 3 is a block diagram for explaining a fire suppression system for automatically tracking ignition points according to one embodiment of the present invention.

[0030] 1 to 3, a fire suppression system 100 for automatically tracking a fire point according to an embodiment of the present invention may include a fire extinguishing agent injection module 110, a fire point automatic tracking detection module 120, and a control unit 130.

[0031] The extinguishing agent injection module 110 may be installed within the monitored area so that the casing 111 can rotate horizontally, and the casing 111 may be installed with a waterproof nozzle 112 that can rotate vertically and can spray the extinguishing agent at the point of fire within the monitored area.

[0032] Here, a plurality of the extinguishing agent injection modules 110 may be installed at predetermined intervals, and it is preferable that adjacent extinguishing agent injection modules 110 are installed at predetermined intervals so that the adjacent monitoring areas from which the extinguishing agent can be sprayed overlap with each other at a predetermined interval.

[0033] For example, the extinguishing agent injection module 110 may include a casing 111 , a waterproof nozzle 112 , an extinguishing agent storage tank 113 , and an on-off valve 114 .

[0034] The casing 111 may be installed in the monitoring area so as to be rotatable in the horizontal direction by a first driving motor (M1) operated by the control unit .

[0035] Here, the first driving motor (M1) operates periodically at intervals set by the control unit 130, rotating the casing 111 at a predetermined angle, thereby detecting whether or not a fire has occurred within the monitored area through the automatic fire tracking detection module 120 installed in the casing 111.

[0036] The waterproof nozzle 112 is installed in the casing 111 so as to be vertically rotatable by a second driving motor (M2) operated by the control unit 130, and sprays the extinguishing agent at the ignition point (S).

[0037] Here, the waterproof nozzle 112 may be manufactured so that the waterproof form of the fire extinguishing agent can be adjusted between spraying and direct spraying, and the waterproof form of the fire extinguishing agent may be controlled by a control unit depending on the distance from the waterproof nozzle 112 to the ignition point.

[0038] For example, when the control unit 130 determines that the ignition point (S) is located within a set distance from the waterproof nozzle 112, it controls the waterproof nozzle 112 so that the fire extinguishing agent can be sprayed in the form of a shower onto the ignition point (S), and when the control unit 130 determines that the ignition point (S) is beyond the set distance from the waterproof nozzle 112, it controls the waterproof nozzle (S) so that the fire extinguishing agent can be sprayed directly onto the ignition point (S).

[0039] The extinguishing agent storage tank 113 is connected to the waterproof nozzle 112 via an extinguishing agent supply line 115 so that the extinguishing agent stored therein can be supplied to the waterproof nozzle 112 via the extinguishing agent supply line 115.

[0040] The on-off valve 114 may be installed on the fire extinguishing agent supply line 115 so that when a fire occurrence signal is transmitted from the fire point automatic tracking detection module 120 to the control unit 130, the on-off valve 114 is operated to be opened by the control unit 130, and the fire extinguishing agent stored in the fire extinguishing agent storage tank 113 is sprayed onto the fire point through the fire extinguishing agent supply line 115 and the waterproof nozzle 112.

[0041] The automatic fire point tracking detection module 120 is installed in each fire extinguishing agent spray module 110 so as to be positioned close to the waterproof nozzle 112, and detects whether or not a fire has occurred within the monitored area, calculates the coordinates of the ignition point (S), and transmits them to the control unit 130.

[0042] For example, the automatic ignition point tracking and sensing module 120 may include an ultraviolet sensor 121 , first and second infrared sensors 122 and 123 , an ignition point coordinate calculation unit 124 , and a thermal imaging camera 125 .

[0043] The ultraviolet light detection sensor 121 is installed in the casing 111 so as to be positioned close to the waterproof nozzle 112, and detects ultraviolet light emitted from a fire source in the monitored area and transmits a fire detection signal to the control unit 130.

[0044] When a fire detection signal is transmitted from the ultraviolet sensor 121 to the control unit 130, the first and second infrared sensors 122 and 123 detect the infrared rays generated by the fire source to perform dual detection of whether or not a fire has occurred, and detect the infrared detection position to transmit the position to the coordinate calculation unit 124 of the ignition point (S).

[0045] For example, the first infrared detection sensor 122 can detect the infrared detection position in the horizontal direction and transmit it to the coordinate calculation unit 124 of the ignition point, and the second infrared detection sensor 123 can detect the infrared detection position in the vertical direction and transmit it to the coordinate calculation unit 124 of the ignition point.

[0046] The ignition point coordinate calculation unit 124 calculates the X-axis and Y-axis coordinates of the ignition point (S) based on the horizontal and vertical infrared sensing positions detected by the first and second infrared sensing sensors 122 and 123, and transmits them to the control unit 130.

[0047] Meanwhile, when the X-axis and Y-axis coordinates of the ignition point (S) are transmitted from the ignition point coordinate calculation unit 124, the control unit 130 rotates the casing 111 horizontally to correspond to the X-axis coordinate of the ignition point (S), and rotates the waterproof nozzle 112 vertically to correspond to the Y-axis coordinate of the ignition point (S), thereby aiming the waterproof nozzle 112 at the ignition point (S).

[0048] The thermal imaging camera 125 is disposed adjacent to the waterproof nozzle 112 and acquires a thermal image of the monitored area to measure the temperature, thereby detecting whether or not a fire has occurred within the monitored area.

[0049] The control unit 130 rotates the casing 111 and the waterproof nozzle 112 of the extinguishing agent injection module 110 based on the coordinates of the ignition point (S) calculated by the automatic fire point tracking module 120, aims the waterproof nozzle 112 at the ignition point (S), and then sprays the extinguishing agent at the ignition point (S).

[0050] Meanwhile, the thermal imaging camera 125 acquires a thermal image of the ignition point (S) when the casing 111 and waterproof nozzle 112 of the extinguishing agent injection module 110 rotates and the waterproof nozzle 112 is aimed at the ignition point (S) based on the coordinates of the ignition point (S) detected by the first and second infrared detection sensors 122, 123, and determines that there is an actual fire only when the temperature of the ignition point is detected to be above the critical temperature, and transmits an extinguishing agent discharge signal to the control unit 130, so that the control unit 130 opens the on-off valve 114 of the extinguishing agent injection module 110 and allows the extinguishing agent to be sprayed at the ignition point (S) through the waterproof nozzle 112.

[0051] That is, in the fire suppression system 100 for automatically tracking an ignition point according to an embodiment of the present invention, the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123 detect the occurrence of a fire in a monitoring area, and the casing 111 and the waterproof nozzle 112 of the fire extinguishing agent injection module 110 rotate based on the coordinates of the ignition point (S) detected by the first and second infrared detection sensors 122 and 123, and even if the waterproof nozzle 112 is aimed at the ignition point (S), the ignition point acquired by the thermal image camera 125 is automatically tracked. When the temperature of the ignition point (S) is no longer detected as being above the critical temperature in the thermal image of the ignition point (S), it is determined that there is no fire in the monitored area, and only when the temperature of the ignition point (S) is detected as being above the critical temperature in the thermal image of the ignition point (S) acquired by the thermal imaging camera 125, it is determined that there is an actual fire, and a fire extinguishing agent discharge signal is transmitted from the thermal imaging camera 125 to the control unit 130, and the control unit 130 activates the fire extinguishing agent spray module 110 to spray the fire extinguishing agent to the ignition point (S) through the waterproof nozzle 112.

[0052] In addition, even if the ultraviolet detection sensor 121 does not detect ultraviolet rays emitted from the fire and the first and second infrared detection sensors 122 and 123 do not detect infrared rays generated from the fire, if an ignition point (S) that is detected to be above the critical temperature is detected in the thermal image video acquired in the monitored area, the thermal imaging camera 125 calculates the coordinates of the ignition point (S) and transmits them to the control unit 130.

[0053] At this time, when the coordinates of the ignition point (S) are transmitted from the thermal imaging camera 125, the control unit 130 determines that a fire has occurred within the monitored area, and rotates the casing 111 horizontally and rotates the waterproof nozzle 112 vertically to correspond to the coordinates of the ignition point (S) transmitted from the thermal imaging camera 125, aiming the waterproof nozzle 112 at the ignition point (S), and then opens the on-off valve 114 to spray the fire extinguishing agent at the ignition point (S) through the waterproof nozzle 112.

[0054] In addition, the fire spot auto-tracking sensing module 120 may further include an AI camera 126 .

[0055] The AI camera 126 is installed in the casing 111 so as to be positioned close to the waterproof nozzle 112, and acquires images within the monitored area, enabling the presence or absence of a fire in the monitored area to be detected from actual images.

[0056] Here, when the thermal imaging camera 125 detects an ignition point (S) that is detected to be above the critical temperature in the thermal image video acquired in the monitoring area while no fire is detected by the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123, the AI camera 126 acquires and analyzes the actual image video of the ignition point (S) to determine whether or not there is an actual fire. If it determines that an actual fire has occurred, it calculates the coordinates of the ignition point (S) and transmits them to the control unit 130.

[0057] When the coordinates of the fire point (S) are calculated from the AI camera 126 and transmitted to the control unit 130, the control unit 130 activates the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123 to re-detect whether or not a fire has occurred at the fire point (S).

[0058] In addition, the infrared detection position detected by the operation of the first and second infrared detection sensors 122, 123 is transmitted to the ignition point coordinate calculation unit 124, which recalculates the coordinates of the ignition point (S) and transmits them to the control unit 130. The control unit 130 then rotates the casing 111 and the waterproof nozzle 112 to correspond to the recalculated coordinates of the ignition point (S), and aims the waterproof nozzle 112 at the ignition point (S).

[0059] Thereafter, the thermal imaging camera 125 acquires further thermal images of the monitored area, remeasures the temperature of the ignition point (S), and determines that there is an actual fire only when the temperature of the ignition point (S) is detected to be above the critical temperature, and transmits a fire extinguishing agent discharge signal to the control unit 130, thereby allowing the control unit 130 to open the on-off valve 114 and spray the fire extinguishing agent at the ignition point (S) through the waterproof nozzle 112.

[0060] In addition, when the ultraviolet detection sensor 121 does not detect ultraviolet rays emitted from the fire, the first and second infrared detection sensors 122 and 123 do not detect infrared rays generated from the fire, and the thermal image acquired by the thermal imaging camera 125 does not detect a temperature above the critical temperature, and no fire is detected, if a fire is detected by the actual image acquired by the AI camera 126 in the monitored area, the AI camera 126 analyzes the actual image of the ignition point (S) to determine whether or not there is an actual fire, and if it determines that a fire has actually occurred, it calculates the coordinates of the ignition point (S) and transmits them to the control unit 130.

[0061] When the coordinates of the ignition point are calculated from the AI camera 126 and transmitted to the control unit 130, the control unit 130 activates the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123 to re-detect whether or not a fire has occurred at the ignition point (S).

[0062] In addition, the infrared detection position detected by the operation of the first and second infrared detection sensors 122, 123 is transmitted to the ignition point coordinate calculation unit 124, which recalculates the coordinates of the ignition point (S) and transmits them to the control unit 130. The control unit 130 then rotates the casing 111 and the waterproof nozzle 112 to correspond to the recalculated coordinates of the ignition point (S), and aims the waterproof nozzle 112 at the ignition point (S).

[0063] Thereafter, the thermal imaging camera 125 acquires further thermal images of the monitored area, remeasures the temperature of the ignition point (S), and determines that there is an actual fire only when the temperature of the ignition point (S) is detected to be above the critical temperature, and transmits a fire extinguishing agent discharge signal to the control unit 130, thereby allowing the control unit 130 to open the on-off valve 114 and spray the fire extinguishing agent at the ignition point (S) through the waterproof nozzle 112.

[0064] In addition, the automatic fire tracking detection module 120 may further include a dust prevention means 127 that operates periodically at intervals set by the control unit 130 and removes dust accumulated on the surfaces of the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122, 123, and on the surfaces of the thermal imaging camera 125 and the AI camera lens 126.

[0065] For example, the dust prevention means 127 may be an air injection nozzle that is operated by the control unit 130 at set intervals to inject air onto the surfaces of the ultraviolet sensor 121 and the first and second infrared sensors 122 and 123, and onto the lenses of the thermal imaging camera 125 and the AI camera 126 to remove dust.

[0066] In this way, the fire suppression system 100 for automatically tracking the ignition point according to one embodiment of the present invention periodically removes dust accumulated on the surfaces of the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122, 123 that detect whether or not a fire has occurred, and on the thermal imaging camera 125 and the AI camera lens 126 using the dust prevention means 127, thereby preventing the ultraviolet detection sensor 121, the first and second infrared detection sensors 122, 123, the thermal imaging camera 125, and the AI camera 126 from not working when a fire occurs.

[0067] Meanwhile, it is preferable that the ultraviolet sensor 121, the first and second infrared sensors 122 and 123, the thermal imaging camera 125, and the AI camera 126 have waterproof and dustproof functions.

[0068] In addition, the fire suppression system 100 for automatically tracking the fire point according to one embodiment of the present invention may further include a communication unit 140 that can transmit a fire detection signal or a danger detection signal from the control unit 130 to the government control center 210 or the manager terminal 220 via wireless communication.

[0069] 1 to 7, a process and effects of detecting and suppressing a fire in a monitoring area using a fire suppression system for automatically tracking a fire point according to an embodiment of the present invention will be described.

[0070] FIG. 4 is a flow chart illustrating a process of suppressing a fire when ultraviolet rays emitted from a fire source in a monitored area are detected by an ultraviolet sensor.

[0071] Referring to FIG. 4, when the fire suppression system 100 for automatically tracking the ignition point according to one embodiment of the present invention is activated and the ultraviolet detection sensor 121 of the automatic fire point tracking detection module 120 detects ultraviolet rays emitted from the fire in the monitored area, the ultraviolet rays 121 transmits a fire detection signal to the control unit 130.

[0072] When a fire detection signal is transmitted from the ultraviolet sensor 121 to the control unit 130, the control unit 130 activates the first and second ultraviolet rays to detect infrared rays generated by the fire, thereby doubly detecting whether or not a fire has occurred.

[0073] When ultraviolet rays are detected by the ultraviolet sensor 121 and infrared rays are detected by the first and second infrared sensors 122, 123, the control unit 130 transmits a danger detection signal to the control center 210 or the manager terminal 220 via the communication unit 140, thereby enabling the manager to monitor whether or not a fire has occurred within the monitored area.

[0074] At this time, the first infrared detection sensor 122 detects the infrared detection position in the horizontal direction and transmits it to the coordinate calculation unit 124 of the ignition point, and the second infrared detection sensor 123 detects the infrared detection position in the vertical direction and transmits it to the coordinate calculation unit 124 of the ignition point.

[0075] In addition, the ignition point coordinate calculation unit 124 calculates the coordinates of the ignition point (s) based on the infrared detection positions detected and transmitted from the first and second ultraviolet detection sensors 122, 123, and transmits them to the control unit 130. The control unit 130 then rotates the casing 111 horizontally to correspond to the coordinates of the ignition point (s) and rotates the waterproof nozzle 112 vertically so that the waterproof nozzle 112 can be aimed at the ignition point (S).

[0076] As described above, when the waterproof nozzle 112 is aimed at the ignition point (S), the thermal imaging camera 125 acquires a thermal image of the monitored area and measures the temperature of the ignition point (S), thereby enabling the presence or absence of a fire in the monitored area to be re-detected.

[0077] At this time, if the temperature of the ignition point (S) is detected to be below the critical temperature through the thermal image image acquired by the thermal imaging camera 125, the thermal imaging camera 125 determines that no fire has occurred, transmits a fire re-detection signal to the control unit 130, and repeats the above process to detect whether or not a fire has occurred in the monitored area.

[0078] Meanwhile, when the temperature of the ignition point (S) is detected to be above the critical temperature through the thermal image video acquired by the thermal imaging camera 125, the thermal imaging camera 125 determines that there is an actual fire and transmits a fire extinguishing agent discharge signal to the control unit 130, which then opens the on-off valve 114, thereby discharging the fire extinguishing agent to the ignition point (S) through the waterproof nozzle 112, thereby quickly extinguishing the fire.

[0079] In addition, the thermal image captured by the thermal image camera 125 is transmitted to the control center 210 or the manager's terminal 220 through the communication unit 140 so that the manager can monitor it.

[0080] Figure 5 is a flowchart illustrating the process of extinguishing a fire when it is detected within the monitoring area by an AI camera.

[0081] Referring to Figure 5, when a fire is detected by the actual image video of the monitoring area acquired by the AI camera 126 while no fire is detected by the ultraviolet detection sensor 121, the first and second ultraviolet detection sensors 122 and 123, and the thermal imaging camera 125, the AI camera 126 analyzes the actual image video of the ignition point to determine whether or not there is an actual fire. If it determines that a fire has actually occurred, it calculates the coordinates of the ignition point (S) and transmits them to the control unit 130.

[0082] At this time, the control unit 130 transmits a danger detection signal to the control center 210 or the administrator terminal 220 via the communication unit 140, and the AI camera 126 transmits actual images of the monitored area to the control center 210 or the administrator terminal 220 via the communication unit, so that the administrator can monitor.

[0083] When the coordinates of the ignition point are transmitted from the AI camera 126 to the control unit 130, the control unit 130 activates the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122, 123 to re-detect whether or not a fire has occurred at the ignition point (S).

[0084] At this time, the infrared detection position detected by the operation of the first and second infrared detection sensors 122, 123 is transmitted to the ignition point coordinate calculation unit 124, and the ignition point coordinate calculation unit 124 calculates the coordinates of the ignition point (S) and transmits them to the control unit 130.The casing 111 and the waterproof nozzle 112 are rotated to correspond to the coordinates of the ignition point (S) recalculated by the control unit 130, and the waterproof nozzle is aimed at the ignition point (S).

[0085] Thereafter, the thermal imaging camera 125 further acquires a thermal image of the monitored area, re-measures the temperature of the ignition point (S), and only when the temperature of the ignition point (S) is detected to be above the critical temperature, it is determined to be a real fire, and transmits a fire extinguishing agent discharge signal to the control unit 130, which controls the opening and closing valve 114 to open, thereby discharging the fire extinguishing agent at the ignition point (S) through the waterproof nozzle 112, thereby quickly putting out the fire.

[0086] FIG. 6 is a flow chart illustrating a process of suppressing a fire when the fire is detected in the monitoring area by the thermal imaging camera.

[0087] Referring to FIG. 6, when no fire is detected by the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123, and an ignition point (S) is detected at a temperature above the critical temperature in the thermal image video acquired by the thermal imaging camera 125 in the monitoring area, the AI camera 126 acquires an actual image video of the ignition point and determines whether or not there is an actual fire. If it determines that an actual fire has occurred, it calculates the coordinates of the ignition point (S) and transmits them to the control unit 130.

[0088] At this time, when the control unit 130 transmits a danger detection signal to the control center 210 or the administrator terminal 220 via the communication unit 140, the thermal image video acquired by the thermal imaging camera 125 and the actual image video acquired by the AI camera 126 are also transmitted to the control center 210 or the administrator terminal 220 via the communication unit 140, allowing the administrator to monitor them.

[0089] Meanwhile, when the coordinates of the fire point (S) are transmitted from the AI camera 126, the control unit 130 activates the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123 to re-detect whether or not a fire has occurred at the fire point (S).

[0090] At this time, the infrared detection position detected by the operation of the first and second infrared detection sensors 122, 123 is transmitted to the ignition point coordinate calculation unit 124, which recalculates the coordinates of the ignition point (S) and transmits them to the control unit 130.The casing 111 and the waterproof nozzle 112 are rotated to correspond to the coordinates of the ignition point (S) recalculated by the control unit 130, and the waterproof nozzle 112 is aimed at the ignition point (S).

[0091] Thereafter, the thermal imaging camera 125 further acquires a thermal image of the monitored area, re-measures the temperature of the ignition point (S), and only when the temperature of the ignition point (S) is detected to be above the critical temperature, it is determined to be a real fire and transmits a fire extinguishing agent discharge signal to the control unit 130, which then opens the on-off valve 114 and discharges the fire extinguishing agent to the ignition point (S) through the waterproof nozzle 112, thereby quickly extinguishing the fire.

[0092] FIG. 7 is another flowchart illustrating a process of suppressing a fire when the fire is detected in the monitoring area by the thermal imaging camera.

[0093] Referring to FIG. 7, when no fire is detected by the ultraviolet detection sensor 121 and the first and second infrared detection sensors 122 and 123, if an ignition point (S) is detected at a temperature above the critical temperature in the thermal image image of the monitoring area acquired by the thermal imaging camera 125, the thermal imaging camera 125 calculates the coordinates of the ignition point (S) and transmits them to the control unit 150.

[0094] At this time, when the control unit 130 transmits a danger detection signal to the control center 210 or the manager terminal 220 through the communication unit 140, the thermal image video acquired by the thermal imaging camera 125 is also transmitted to the control center 210 or the manager terminal 220 through the communication unit 140 so that the manager can monitor it.

[0095] When the coordinates of the ignition point (S) are transmitted to the control unit 130, the control unit 130 rotates the casing 111 and the waterproof nozzle 112 to correspond to the coordinates of the ignition point (S), aims the waterproof nozzle 112 at the ignition point (S), and then opens the open / close nozzle 114 to spray the extinguishing agent at the ignition point (S) through the waterproof nozzle 112, thereby quickly extinguishing the fire.

[0096] As described above, the fire suppression system 100 for automatically tracking ignition points according to one embodiment of the present invention detects whether or not a fire has occurred in the monitored area in real time through the automatic fire point tracking detection module 120, tracks the ignition point (S), and very quickly and accurately determines whether or not a fire has actually occurred at the detected ignition point (S), and accurately aims and sprays a fire extinguishing agent at the ignition point (S), thereby quickly suppressing the fire at an early stage.

[0097] For example, in the case of an early ignition point of a fire where there is no flame or smoke and only a small spark is alive, smoke and ultraviolet or infrared rays are not detected, so a fire monitoring system using a normal camera or an ultraviolet or infrared sensor cannot detect the fire, which makes it difficult to extinguish the fire in its early stages.

[0098] However, the fire suppression system 100 for automatically tracking the ignition point according to one embodiment of the present invention can quickly extinguish the fire in an early stage by tracking the ignition point (S) detected by the thermal imaging camera 125 as exceeding the critical temperature, even in the early stage of a fire when the fire is not detected by the ultraviolet detection sensor 121 or the first and second infrared detection sensors 122 and 123, no flames or smoke are generated, and only small sparks are alive, and then aiming at the ignition point (S) and spraying a fire extinguishing agent.

[0099] In addition, even in the case of an ignition point (S) in the early stage of a fire where the ultraviolet detection sensor 121, the first and second infrared detection sensors 122, 123, and the thermal imaging camera 125 do not detect a fire or a flame above the critical temperature and only smoke is burning, the AI camera 126 can detect smoke using actual images acquired by the AI camera 126, quickly detect and track the ignition point (S), and then aim at the ignition point (S) and spray a fire extinguishing agent to quickly extinguish the fire in the early stage.

[0100] In this way, the fire suppression system 100 for automatically tracking the ignition point according to one embodiment of the present invention detects the presence or absence of a fire in the monitored area in multiple overlapping manners in response to various initial fire occurrence conditions, and quickly and accurately detects and tracks the ignition point (S) at the initial stage of the fire. If it determines that a fire has actually occurred, it aims the waterproof nozzle 112 at the ignition point (S) and sprays a fire extinguishing agent, thereby quickly suppressing the fire at the initial stage of the fire.

[0101] In the above detailed description of the present invention, reference has been made to preferred embodiments of the present invention, but it will be understood that a person skilled in the art or having ordinary knowledge in the art can make various modifications and changes to the present invention without departing from the spirit and technical scope of the present invention as set forth in the claims below.
