Smart fire suppression method and system {SMART FIRE SUPPRESSION METHOD AND SYSTEM}

The present invention relates to an automatic fire suppression system, and more particularly, to a smart fire suppression method and system capable of minimizing human life and property damage through initial fire suppression through mist-type extinguishing material injection, and a smart scan fire suppression device therefor It is about.

Disasters caused by fire are the disasters that occur most frequently in the surrounding area, and in the case of large-scale fires, most of them occur because an initial response is not made.

In other words, a fire is a disaster that inevitably accompanies material property damage and even loss of life if the initial response is not properly performed.

When such fires are classified by combustion object, they can be classified into general fires (Class A fires), flammable liquid and gas fires (Class B fires), electrical fires (Class C fires), and metal fires (Class D fires). Here, fires caused by combustion of combustibles containing hydrocarbons, such as Class A, Class B, and Class C fires, are called hydrocarbon fires, and Class D fires are called non-hydrocarbon fires. do.

At this time, a hydrocarbon-based fire is a disaster that can be commonly encountered during fire accidents, and smoke and flames are generated as paper, wood, synthetic resin, or flammable liquid is burned.

In addition, non-hydrocarbon-based fires do not have flame shimmer and wavelength, do not maintain a natural combustion state, and have characteristics of rapid transition.

Detection devices (sensor sensor ) has been developed.

However, even if a fire is detected using the above-mentioned detection device and an employee of the jurisdiction is mobilized by notifying it, there is a problem in that it is difficult to avoid a large-scale fire because the progress of the fire has already been made considerably.

Meanwhile, in order to solve the above problems, Korean Patent Registration No. 10-1178927 discloses a video monitoring fire extinguishing system, and Korean Patent Registration No. 10-1281494 discloses an intelligent camera automatic control system using a smartphone. there is.

However, the systems described above have a problem in that they cannot accurately spray or fire the extinguishing material injected from the fire extinguishing device to the fire area.

In addition, Korean Registered Patent Publication No. 10-09354480 discloses a remote fire monitoring device that operates to enable initial extinguishment when a fire occurs while enabling a remote location to check whether or not a fire has occurred. However, the remote fire monitoring device includes a video capture unit and a fire detection unit in a body case, and a fire extinguishing unit capable of spraying an extinguishing material in the direction of the video capture unit and the fire detection unit, but the area where the fire occurs through the fire extinguishing unit. There is a disadvantage that the fire extinguishing material cannot be sprayed accurately.

In addition, Korean Patent Registration No. 10-1450823 (May 23, 2014) discloses a camera-linked remote fire extinguishing system that detects a fire through a CCTV camera and extinguishes the detected fire by spraying an extinguishing material through a provided fire extinguishing device. This has been disclosed. In particular, the camera-linked remote fire extinguishing system is characterized in that it is possible to control the spraying and firing strength of the extinguishing material by creating an aiming point at the center where the extinguishing material is sprayed or fired and adjusting the pressure.

However, the camera-linked remote fire extinguishing system has a problem in that it cannot identify the cause of fire and cannot adaptively extinguish the fire according to the identified cause of fire.

In addition, the conventional fire suppression system injects a large amount of water or other extinguishing materials when a fire is detected, so there is a problem in that property damage due to fire suppression is great regardless of the scale of the fire.

1 is a block diagram for explaining the structure of a smart fire suppression system according to an embodiment of the present invention.

For convenience of explanation, the smart fire suppression system 100 will be simply named “system” and described below.

Referring to FIG. 1, the system 100 includes first through nth smart scan fire suppression devices 10, a smart home control device 20, a control server 30, a statistics and analysis server 40, a manufacturer server ( 50), a subscriber server 60, a government office server 70, and other servers 80.

All of the components of the system 100 described above are not necessarily essential, and may be configured to include more or less components.

Components of the system 100 may mutually exchange information through a communication network. The communication network may be a wired communication network—for example, an internet network, an intranet, etc.—but is not limited thereto, and some components may mutually exchange information through a wireless network.

The first to nth smart scan fire suppression devices 10 may be interlocked with each other. For example, the first to nth smart scan fire suppression devices 10 may be interoperated through the control server 30, but this is only one embodiment, and the first to nth smart scan fire suppression devices ( 10) may perform Machine-To-Machine (M2M) communication by being directly connected by wire or wirelessly.

As an embodiment, at least one of the first to nth smart scan fire suppression devices 10 may be driven as a relay (or repeater) to relay communication between remotely arranged smart scan fire suppression devices.

For example, when the first smart scan fire suppression device cannot communicate with the control server 30 after detecting a fire, it communicates with the control server 30 through at least one smart scan fire suppression device among second to n adjacent ones. You can try connecting.

The first to nth smart scan fire suppression devices 10 may control utility supply control for each fire suppression stage, indoor ventilation, and transmission of a fire warning alarm in conjunction with the smart home control device 20 . As an example, utilities may include city gas and electricity.

When a fire is detected by any one of the first to n smart scan fire suppression devices 10, the smart scan fire device captures an image of a fire detection point (or ignition point) through a camera provided, It is possible to transmit real-time captured fire images to the control server 30 together with its own device identifier (or preset subscriber identifier corresponding to the corresponding device), coordinates (or location) information of a fire occurrence point, and fire suppression steps.

The control server 30 includes a statistics and analysis server 40, a manufacturer server 50, a subscriber terminal 60, a government office server 70 and The fire image received by at least one of the other servers 80 may be transmitted in real time.

For example, the fire suppression step may be divided into first to third fire suppression steps.

When the temperature of the ignition point exceeds the first threshold, the smart scan fire suppression device enters the first fire suppression stage, blocks the gas, and sprays water mist at the first speed to the ignition point to try to extinguish the fire. can do.

When the temperature of the ignition point exceeds the second threshold during fire suppression in the first fire suppression stage, the smart scan fire suppression device enters the second fire suppression stage, cuts off electricity, and sprays water mist at a second speed to the ignition point. You can try to extinguish the fire. Here, the second speed may be greater than the first speed of the first fire suppression step, and the second threshold may be set to a value greater than the first threshold.

In the second fire suppression step, the smart scan fire suppression apparatus may control a sprinkler to be operated when it is determined that fire suppression has failed because the temperature of an ignition point exceeds a third threshold during fire suppression in the second fire suppression step. Here, the third threshold may be set to a value greater than the second threshold for determining entry into the second fire suppression step.

The control server 30 may transmit fire state information and real-time video information only to the corresponding subscriber terminal 60 and the statistics and analysis server 40 when the smart scan fire suppression device enters the first fire suppression phase. Here, the fire state information may be transmitted at a certain period or when a specific event occurs, and includes current time information, spray head information being used for fire suppression, information on the type of extinguishing material being used for suppressing fire, usage by type of extinguishing material and (or accumulation). consumption) information, fire extinguishing material injection speed information, fire extinguishing material spray area information, harmful gas detection information, and the like.

The control server 30 may transmit the fire image received from the smart scan fire suppression device to the corresponding subscriber terminal 60 and the statistics and analysis server 40 through a real-time streaming service.

The statistics and analysis server 40 may calculate various types of statistical information and analysis information based on the fire image information and fire situation information received from the control server 30 .

For example, the statistical information includes statistical information on the frequency of occurrence of fires by year/quarter/month/day/time, statistical information on average fire suppression time, statistical information on the amount of extinguishing materials used in fire suppression, statistical information on average spray speed of fire extinguishing materials, and statistical information on fire suppression. Statistical information on the number of entries by stage may be included.

For example, the analysis information may include analysis information of an extinguishing substance having the highest effect for each fire type, analysis information of an extinguishing substance that can be mixed for each fire type, and the like.

The control server 30 may transmit a fire warning message including the fire image and the fire state information to the government office server 70 when the smart scan fire suppression device enters the second fire suppression step.

When the fire suppression is completed, the control server 30 may transmit related fire information to other servers 80 such as insurance companies.

The control server 30 maintains a device identifier corresponding to the smart scan fire suppression device, address information of the place where the smart scan fire suppression device is installed, subscriber information, subscriber contact information, and subscriber's fire insurance company information in a database (not shown) can manage

As an embodiment, when the smart scan fire suppression device is installed in a dense residential space, such as an apartment, building, multi-family house, or townhouse, the smart scan fire suppression device may cooperate with an adjacent smart scan fire suppression device to extinguish a fire.

According to an embodiment, when receiving a fire alarm message from the first smart scan fire suppression device, the control server 30 refers to the first smart scan fire suppression device and the smart scan fire suppression device disposed within a predetermined radius to the database. can be identified. The control server 30 may transmit a predetermined control command to at least one identified smart scan fire suppression device to control the fire extinguishing agent to be sprayed. Through the above embodiment, it is possible to effectively prevent a fire from spreading from a fire-occurring floor to another adjacent floor when an apartment fire occurs.

A smart scan fire suppression device according to another embodiment sends a fire warning alarm message to the adjacent smart scan fire suppression device(s) connected wirelessly and/or wired when the fire suppression step enters a certain level or higher after detecting a fire. can be broadcast. At this time, the smart scan fire suppression device(s) receiving the broadcasting warning alarm signal may start spraying the extinguishing material to build a firewall.

The smart scan fire suppression device according to the embodiment is not only major buildings such as cultural properties, museums, art galleries, and data centers, but also high-end residential spaces, hospitals, smart factories, broadcasting stations, hotels, VIP rooms, mobile buildings, air domes, and container objects. It has the advantage that it can be installed and used in various ways such as rooms.

The smart scan fire suppression device according to the embodiment can not only extinguish a fire using a very small amount of water - about 10% - compared to a conventional sprinkler, but also spray a small amount of water at high pressure to reduce fine water particles of 1000 μm or less. Since it supports the mist method, which is a method of suppressing fire with a fire, it has the advantage of minimizing damage to buildings, electronic devices, and furniture.

The high-pressure hose connected to the spray head of the smart scan fire suppression device according to the embodiment has the advantage of being dry and free from leakage, and can be easily installed using a general water supply pipe rather than a separate fire pipe by using a small amount of water.

A smart scan fire suppression device according to an embodiment may include a plurality of spraying units, and each spraying unit may include a spraying head and a camera. The smart scan fire suppression device can control a plurality of cameras to perform time-division or simultaneous fire scans. Through this, the fire detection blind spot can be effectively solved.

The smart scan fire suppression device 200 has an advantage of excellent initial fire suppression performance because it controls the fire extinguishing material to be sprayed immediately even when the temperature of the ignition point is low at 60 degrees or less after detecting the occurrence of fire.

The pyrolysis process occurs when the fuel at a certain point begins to decompose into combustible gases (eg CH4 = methane) and energy (heat) is applied to the fuel surface. The oxidation process occurs when more energy (heat) is applied to the atmosphere and combustible gases. At this point, the oxygen molecules found in the atmosphere are separated and travel with the combustible gas molecules. This process releases energy and is seen in the form of fire, flames and heat. Since fire entry using water mist according to an embodiment of the present invention can interfere with both the pyrolysis process and the oxidation process, it has the advantage of being very effective in suppressing fire.

Here, the spray head mode may largely include a direct mode in which the extinguishing material is sprayed in a straight line, a radiation mode in which the extinguishing material is sprayed in a radial manner, and a beam mode in which the extinguishing material is sprayed in a beam form.

For example, the main control unit 220 may calculate an area of a region having a temperature equal to or higher than a predetermined temperature around the ignition point, and determine a jetting head mode based on the calculated area.

In addition, the main control unit 220 determines the cause of the fire based on the identified ignition point coordinates and the detailed map of the fire suppression target area previously stored in the memory 209 after detecting the fire, and the fire extinguishing material corresponding to the determined cause of the fire. , the spray pattern and spray density, etc. can be determined.

For example, the image generation module may include a microbolometer-type focal plane array that responds to infrared radiation having a specific wavelength range.

For example, a specific wavelength range may be 8-12 microns, but is not limited thereto.

In this case, the main controller 230 may determine whether or not a fire occurs based on the pixel stream of the focal plane array.

In addition, among the video signals input through the optical element 201 , a UV signal having a specific wavelength may be filtered and then provided to the smoke detector 206 .

To this end, filters (not shown) may be provided between the optical element 201 and the heat detection unit 205 and between the optical element 201 and the smoke detection unit 206, respectively.

The optical lens according to the embodiment may be equipped with a night vision function capable of detecting a fire phenomenon—for example, flame and smoke—even in low light conditions.

The heat detection unit 205 may detect a flame, which is a potential risk factor for a fire, based on an image signal from which long-wavelength infrared rays are filtered. When the flame is sensed, the heat detection unit 205 may drive the image generating module of the image capturing unit 204 .

Since the image generation module according to the embodiment is automatically driven only when infrared rays of a specific wavelength are detected, standby power consumption of the device 200 can be minimized.

The smoke detection unit 206 may detect smoke, which is a potential risk factor for fire, based on an image signal from which ultraviolet rays of a specific wavelength are filtered.
