Description

FIRE DETECTION SYSTEM THAT CAN PREVENT UNWANTED ALARM

The present invention relates to a fire detection system that detects the occurrence of a fire and outputs a fire alarm, and more particularly, to a fire detection system capable of automatically limiting the output of a fire alarm by temporarily generated dust or cigarette smoke. will be.

Recently, the form of buildings is becoming super-high-rise, underground, and large-scale due to the improvement of land efficiency and the tendency of landmarks, etc., and this trend is becoming a trend of buildings not only in Korea but also around the world. In addition, it is developing into a multiplex-type complex where commercial facilities for various purposes such as theaters, restaurants, shopping centers, karaoke rooms, and danran bars coexist.

However, due to the increase of high-rise, underground, large-scale, and commercial facilities in buildings, the use of various interior materials for splendid interiors along with the increase of internal divisions, the scale of damage to life and property in the event of a fire is unimaginably large. .

As a result, the importance of a firefighting system capable of preventing, alerting and suppressing fires is growing. Among them, the automatic fire detection facility conducts the initial fire extinguishing and early suppression of fires through the control of fire extinguishing facilities and smoke control facilities linked together with safe evacuation guidance through primary detection and early warning of fires, and determines the scale of fire damage. It is a firefighting system that plays a central role.

According to the definition of terms in Article 3 of the Fire Safety Standards for Automatic Fire Detection Facilities (NFSC 203), receivers, repeaters, detectors and transmitters are defined as representative devices of automatic fire detection facilities as follows.

The receiver refers to a device that directly receives fire information emitted from a detector or a transmitter or receives it through a repeater to display and alert the occurrence of a fire.

The repeater refers to a device that receives a signal according to the operation of a detector, a transmitter, or an electrical contact and transmits it to a control panel of a receiver.

The detector refers to a device that automatically detects heat, smoke, flame or combustion products generated during a fire and transmits it to a receiver.

The transmitter refers to a device that manually transmits a fire occurrence signal to a receiver. Currently, domestic transmitters have a 4-wire system of circuit (input) line, common line, answer line, and telephone line, which has a PUSH button switch, answer indicator light, and telephone jack. The operation method is a one-dimensional method that transmits ON/OFF type contact signals by simply pressing the PUSH button switch. The response line can check the operation of the transmitter even without the response line due to the development of power line communication technology, and the response indicator lamp can be turned on and the lighting state can be continued. In addition, the current telephone function using the handset of the transmitter was introduced in the 1980s for facility maintenance and is currently not used due to the widespread use of mobile phones. In addition, a handset must be provided for the telephone function, but it is not provided anywhere in the building, so it is a function that is practically unnecessary.

On the other hand, in recent years, smoke detectors characterized by the speed of fire detection are mainly adopted as fire detectors, and among smoke detectors, a scattering type photoelectric type having a simple configuration and excellent sensitivity is generally used. However, photoelectric fire detectors that use the scattering of light by smoke particles have sensitive detection sensitivity, so non-fire alarms are a problem. Here, the non-fire alarm means that the fire detection device is operated by factors other than heat, smoke, and flame caused by a fire to generate a fire alarm. In other words, it refers to the false detection of a fire due to a cause other than a fire while the fire detector is operating normally.

The main causes of such non-fire alarms are malfunctions due to increased humidity in the air during the rainy season, and smoke detectors due to cigarette smoke or automobile exhaust.

According to the National Fire Information Center of the National Fire Service, the number of non-fire alarms (misidentified) dispatches occurred in July, August, and December. In summer, there is a lot of precipitation compared to other seasons, so it is affected by moisture. In December, as the winter season enters, the demand for heating increases and condensation occurs due to the external temperature difference.

There is a problem in that there is a cost for dispatching a fire engine due to such a non-fire report and checking the cause of the person concerned, and there is a problem in that a large loss occurs that cannot quickly respond to a real fire due to the dispatch of a fire engine due to a non-fire report.

Republic of Korea Patent Registration No. 10-2020-0082823 (Announcement on Jul. 8, 2020) Republic of Korea Patent Registration No. 10-1720410 (2017.03.27 Announcement) Republic of Korea Patent Registration No. 10-2054935 (Notice on Dec. 12, 2019) Republic of Korea Patent Registration No. 10-1963111 (published on July 31, 2019)

Therefore, an object of the present invention is to analyze the fire information collected through the fire detector and determine that it is a non-fire if it falls within a preset standard so as not to output a fire alarm, thereby preventing non-fire information caused by factors other than fire. To provide a fire detection system.

A detector and a fire information database in which a boundary value for each fire element and a prior correction value are stored, a real-time correction value is generated based on the measured value of the preceding correction value and real-time measurement information, and the fire element having the same real-time correction value A fire information analyzer that generates and transmits fire occurrence information when reaching the threshold value of , a fire alarm that outputs a fire alarm signal, and a fire detector that is connected to the fire detector, the fire information analyzer, and the fire alarm provide real-time measurement information and fire occurrence information A fire detection system capable of preventing non-fire alarms, including a fire receiver that receives, provides the real-time measurement information to a fire information analyzer, and generates a fire alarm signal as the fire occurrence information is received and provides it to a fire alarm do.

According to the present invention, even if fire information is collected by instantaneous dust or cigarette smoke, the fire information is collected by factors other than fire by analyzing the fire information using the average value weighted to the past data instead of directly applying the fire information. Fire information can be excluded from the occurrence of fire alarms.

As described above, since the present invention can prevent non-fire reports caused by factors other than fire, it fundamentally blocks the occurrence of costs such as dispatch of fire trucks and identification of the cause of persons concerned, and prevents fire trucks from dispatching due to non-fire reports to prevent a real fire. can respond quickly to

In addition, since the present invention can prevent a non-fire alarm through the fire information analysis function of the receiver even if a general fire detector is used, there is no need to replace the existing fire detector, and accurate fire detection performance with minimal environmental impact can be obtained. can

In addition, according to the present invention, when the fire information collected through the fire detector is analyzed according to the surrounding environment of the area where the fire detector is installed, it is possible to select a target to be given a high weight among recent data and past data, so that the installation environment of the fire detector Fire information can be analyzed through different criteria depending on the

Referring to FIG. 1 , the automatic fire extinguishing system according to the present invention includes a plurality of fire detectors 100 .

The fire detector 100 is distributed for each monitoring area in order to monitor fires generated in each monitoring area, and transmits the generated real-time measurement information to the fire receiver 400 . In this case, the fire detector 100 may use an analog detector that detects heat, smoke, or both.

In this way, if an analog detector is used instead of a digital detector, fire factors related to fire such as temperature or smoke concentration can be continuously monitored, and the cable connecting the fire detector 100 by non-fire causes rather than fire. It can be managed so that the fire alarm is not output even if it is cut.

More specifically, the analog detector detects the first fire element, generates real-time measurement information including the measured value of the fire element and address information, and transmits the real-time address information to the fire receiver 400 through a communication loop. . In other words, an address-type detector providing address information may be used as the fire detector 100 . In this way, if the address information is set for each fire detector 100, the location of the fire can be accurately specified and the fire extinguisher installed at the specified location of the fire can be operated, thereby minimizing the range of damage caused by the operation of the fire extinguisher. and early fire extinguishing is possible.

As a specific aspect, the fire detector 100 according to the present invention detects a fire element and generates a fire detection module for generating real-time measurement information including a measurement value of the fire element, and the real-time measurement information generated from the fire detection module. and a controller 120 that transmits to the receiver 400 .

2 is a block diagram showing a fire detector according to the present invention.

The fire detection module constituting the fire detector 100 according to the present invention includes at least one of a smoke sensor 112, a temperature sensor 114, a gas sensor 116, and a fine dust sensor 118 as shown in FIG. Although possible, preferably a smoke sensor 112 or a temperature sensor 114 is included. This is because temperature and smoke concentration are best suited to distinguish fire occurrence.

The smoke sensor 112 may sense the smoke concentration through a photoelectric method. Such a smoke sensor 112 may increase or decrease the sensitivity to smoke concentration.

The temperature sensor 114 is a sensor that measures heat (temperature), and may sense heat (temperature) through a constant temperature method using a thermistor. In addition, the thermal sensor combines the two temperature sensors 114 to increase the thermal time constant of one side, decrease the thermal time constant of the other side, and detect the temperature increase rate from the detected temperature difference. Heat (temperature) can be detected through

The gas sensor 116 may sense the gas concentration of the organic material generated by heat generation through an electrochemical method. Here, the organic material generated by heat generation may be any one of carbon monoxide, carbon dioxide, hydrogen chloride, BHT gas, chlorine and ethylene.

The fine dust sensor 118 may detect the atmospheric state in the measurement area through a light scattering method. Here, the light scattering method refers to a method of measuring the amount of scattered light using the principle that the collided light is scattered in various directions when light is irradiated on a material and obtaining the concentration of fine dust from the value. In addition, fine dust includes carbon compounds such as soil dust, plant pollen, soot generated from burning fossil fuels, methane, alcohol, benzene, and phenol generated when organic matter is burned, nitrogen oxides, and, It may be any one or more dust of any one of sulfur oxides.

Such particulate matter (PM) is classified into fine dust (PM10), ultrafine dust (PM2.5), and ultrafine dust (PM1.0) according to particle size. The particle size of PM10 is 10 μm or less in diameter, PM2.5 has a particle size of 2.5 μm or less in diameter, and PM1.0 has a particle size of 1.0 μm or less in diameter.

The controller 120 constituting the fire detector 100 according to the present invention is connected to the fire receiver 400 through a communication line or a communication loop, and transmits real-time measurement information to the fire receiver 400 .

The controller 120 stores the address information given to the fire detector 100 by itself, and when the measured value of the fire element is collected from the fire detection module, the address information is added to the measured value to generate real-time measurement information. provides And the controller 120 transmits the real-time measurement information including the address information and the measured value to the fire receiver 400 to determine where the fire detector 100 that detects the occurrence of a fire is installed. helps you to specify

If necessary, the address information may be coordinate information indicating a location where the fire detector 100 is installed, or may be identification information for matching coordinate information in the fire receiver 400 .

If necessary, the fire detector 100 installed in a single monitoring area may include a first analog detector and a second analog detector.

The first analog detector is installed in each monitoring area, detects the first fire element and generates first real-time measurement information including the measurement value and address information of the first fire element, and the first real-time measurement information It can be transmitted to the fire receiver 400 .

Each of the first analog sensors installed for each monitoring area may be connected in series to the first line, may be connected in series to the second line, or may be connected in series and in parallel through several lines. At this time, the first line and the second line may connect a plurality of first analog detectors in series, and not only serve as a communication line between each first analog detector and the fire receiver 400 but also each first analog detector It can also serve to supply power to the

The second analog detector is installed in each monitoring area, detects a second fire element, and generates second real-time measurement information including the measurement value and address information of the second fire element, the second real-time measurement information It can be transmitted to the fire receiver 400 .

Each of the second analog sensors installed for each monitoring area may be connected in series to the first line, may be connected in series to the second line, or may be connected in series and in parallel through several lines. In this case, the first line and the second line may connect a plurality of second analog detectors in series, and not only serve as a communication line between each second analog detector and the fire receiver 400 but also each second analog detector It can also serve to supply power to the

In other words, both the first analog detector and the second analog detector for detecting different fire elements may be installed in each monitoring area.

Referring to FIG. 1 , the automatic fire extinguishing system according to the present invention includes a fire information analyzer 200 .

The fire information analyzer 200 analyzes real-time measurement information transmitted from the fire detector 100 so as to track the monitoring area where a fire occurred, and the measured value of the fire element reaches a threshold value for determining the occurrence of a fire. Even so, in order to prevent the occurrence of non-fire alarms due to cigarette smoke, etc., instead of using the measured values as they are, real-time correction values are generated and used based on the measured values.

In other words, the fire information analyzer 200 does not generate fire occurrence information even if the measured value of the fire element reaches the boundary value of the same fire element, and uses the average value weighted to the past data, so that the average value is the boundary value. If it exceeds the value, fire information is generated.

More specifically, the fire information analyzer 200 is provided with a fire information database in which boundary values for each fire element and prior correction values are stored. And the fire information analyzer 200 generates a real-time correction value based on the measured value of the preceding correction value and real-time measurement information, and when the real-time correction value reaches the boundary value of the same fire element, the fire occurrence information is generated It is transmitted to the receiver 400 . Here, the prior correction value means a real-time correction value immediately before the real-time correction value is calculated.

3 is a graph showing a measured value of a fire element according to the present invention and a real-time correction value generated based thereon.

Referring to FIG. 3 , the real-time correction value is preferably calculated as an exponential weighted moving average value generated based on a weight α set by an administrator, a preceding correction value, and a real-time measurement value.

Here, the weight α may be set in the range of 0.05 to 0.25. These weights are set high when the reflection ratio of the near prior correction value is to be increased, and set low when the reflection ratio of the distant preceding correction value is to be increased.

As a specific embodiment, the real-time correction value according to the present invention may be calculated through [Equation 1] below.

[Equation 1]

Real-time correction value = (1-weight)*preceding correction value+(weight*real-time measurement)

Therefore, when the real-time measured value is higher than the preceding correction value, the real-time correction value is calculated to be higher than the preceding correction value between the preceding correction value and the real-time measured value, and when the real-time measured value is lower than the preceding correction value, the real-time correction value is preceded Between the correction value and the real-time measurement value, it is calculated lower than the previous correction value.

In addition, the fire information analyzer 200 may be configured to readjust the initially set weights by comparing and analyzing whether or not fire occurrence information is generated and the fire occurrence determination information transmitted from the fire receiver 400 .

Specifically, the fire information analyzer 200 generates fire occurrence information and transmits it to the fire receiver 400 , receives the fire occurrence determination information from the fire receiver 400 , and analyzes the fire occurrence determination information to initially set The weight α is readjusted.

For example, the fire information analyzer 200 generates fire occurrence information, transmits it to the fire receiver 400, analyzes the fire occurrence determination information provided from the fire receiver 400, and if a fire occurrence signal is included, the existing weight (α) keep as it is In addition, the fire information analyzer 200 generates fire occurrence information and transmits it to the fire receiver 400. If a non-fire alarm occurrence signal is included in the fire occurrence determination information provided from the fire receiver 400, the weight of recent data is given high. Therefore, a new weight is generated by reducing 0.005 to 0.02, preferably 0.01, from the existing weight α, and a real-time correction value is calculated using the new weight.

In addition, when the fire information analyzer 200 includes a fire occurrence signal in the fire occurrence determination information provided from the fire receiver 400 in a situation in which the fire occurrence information is not transmitted to the fire receiver 400, the weight of recent data is given low. Therefore, a new weight is generated by increasing 8% to 12%, preferably 10%, from the existing weight α, and a real-time correction value is calculated using the new weight. At this time, since the case in which fire occurrence information is not generated in a fire situation is a more dangerous situation than the case in which fire occurrence information is generated in a non-fire situation, instead of applying an increased weight of 0.005 to 0.02, 8% to apply a new weight increased by 12%.

In addition, if the fire information analyzer 200 includes a non-fire alarm occurrence signal in the fire occurrence determination information provided from the fire receiver 400 in a situation in which the fire occurrence information is not transmitted to the fire receiver 400, the existing weight α is maintained as it is. keep

On the other hand, the fire information analyzer 200 according to the present invention generates fire caution information including address information when the measured value of real-time measurement information reaches the threshold value of the same fire element and provides it to the fire receiver 400 . .

As an embodiment, the fire information analyzer 200 according to the present invention is a boundary value of one or less real-time correction values when there are two or more real-time measurement information having the same address information among the real-time measurement information collected at the same time. When reaching , fire occurrence information is not generated, and when two or more real-time correction values reach a threshold value, fire occurrence information including source information can be generated and provided to the fire receiver 400 . Here, the source information includes the fire element that is the detection target of the measured value such as smoke, temperature, gas, fine dust, etc.

As another embodiment, the fire information analyzer 200 according to the present invention provides a real-time correction value related to each real-time measurement information when there are two or more real-time measurement information having the same address information among the real-time measurement information collected at the same time. When the threshold value is reached, fire occurrence information including source information may be generated and provided to the fire receiver 400 .

Specifically, the fire receiver 400 generates a real-time correction value based on the measured value of the fire element included in the first real-time measurement information, and when the real-time correction value reaches a threshold value, the fire including source information and address information Generates occurrence information. And the fire receiver 400 generates a real-time correction value based on the measured value of the fire element included in the second real-time measurement information, and when the real-time correction value reaches a threshold value, fire occurrence information including source information and address information create

In addition, the fire information analyzer 200 may transmit the address information included in the fire caution information to the on-site inspector terminal. To this end, the fire information analyzer 200 may store the contact information of the on-site inspector's terminal, and when the fire caution information is generated, the inspection request information including the address information may be transmitted to the on-site inspector's terminal.

In this way, even if it is temporary, when the measured value exceeds the threshold, a fire occurrence or status check of the fire detector 100 may be requested by providing the address of the fire detector 100 that has transmitted the real-time measurement information to the on-site inspector.

If necessary, the fire information analyzer 200 may be formed to be built in the fire receiver 400 .

Referring to FIG. 1 , the automatic fire extinguishing system according to the present invention includes a fire alarm 300 .

The fire alarm 300 is connected to the fire receiver 400, and outputs the fire alarm signal in sound or image so that the user can check the fire alarm signal through hearing or vision.

To this end, the fire alarm 300 may include a sound output device, an image output device, or both.

The sound output device may be configured to collect the fire occurrence information and output a warning sound when the fire information analyzer 200 determines that a fire has occurred and generates fire occurrence information. In addition, the sound output device may output a guide sound for a quick evacuation according to a fire. Here, the warning sound and the evacuation route guide sound may be output as voice output after voice recording by the voice chip.

The image output device is connected to the fire receiver 400 and may be configured in the form of a monitor. When the first fire alarm signal is provided from the fire receiver 400, the image output device outputs characters such as '**zone fire' as an image, and when the second fire alarm signal is provided from the fire receiver 400, ' **Fire occurrence confirmation in the area' is output as an image.

If necessary, the fire alarm 300 may be composed of a central alarm installed in the control center and a monitoring area alarm installed in each monitoring area.

Here, the central alarm outputs a fire alarm signal within the control center so that the manager working in the control center of the building can recognize the occurrence of a fire, and the monitoring area alarm allows residents or visitors of the monitoring area to recognize the occurrence of a fire. Outputs a fire alarm signal within the monitoring area.

The automatic fire extinguishing system according to the present invention may further include a fire extinguisher (not shown).

The fire extinguisher is installed in each monitoring area, and serves to spray the extinguishing agent under the control of the fire receiver 400 so as to extinguish a fire at an early stage. To this end, the fire extinguisher is connected to a fire receiver 400 .

As a specific aspect, the fire extinguisher according to the present invention includes a fire extinguishing container in which the extinguishing agent is accommodated, a fire extinguishing valve that turns on/off the passage through which the extinguishing agent is discharged from the fire extinguishing container, and is connected to the fire extinguishing valve to spray the extinguishing agent passing through the fire extinguishing valve. It may include a fire extinguishing nozzle and a driving device for controlling the fire extinguishing valve according to an operation signal transmitted from the fire receiver 400 .

Referring to FIG. 1 , the automatic fire extinguishing system according to the present invention includes a fire receiver 400 .

The fire receiver 400 is connected to the fire detector 100, the fire information analyzer 200, and the fire alarm 300 to receive real-time measurement information and fire occurrence information, and the real-time measurement information is converted into the fire information analyzer 200 ) is provided in

The fire receiver 400 generates a fire alarm signal as the fire occurrence information is received and provides it to the fire alarm 300 . In this case, the fire alarm signal refers to the first fire alarm signal to distinguish it from the second fire alarm signal generated by the fire receiver 400 when the fire caution information is received.

More specifically, when the fire occurrence information is received from the fire information analyzer 200, the fire receiver 400 extracts a monitoring area alarm matching the address information of the fire occurrence information, and uses the extracted monitoring area alarm and central alarm. Each of the first fire alarm signals is provided. This is to output a fire alarm in both the monitoring area where the fire occurred and the control center.

The fire receiver 400 generates a second fire alarm signal as the fire caution information is received from the fire information analyzer 200 , and provides the second fire alarm signal to the central alarm. This is because the fire caution information is highly likely to be generated by non-fires such as cigarette smoke, so that the measured value reaching the threshold does not output a fire alarm in the monitoring area detected by the fire detector 100, and fires only in the control center to output an alarm.

The fire receiver 400 may store address information of each fire extinguisher. In addition, when fire occurrence information including address information is provided from the fire information analyzer 200, the fire receiver 400 selects a fire extinguisher matching the address information and generates an operation signal of the fire extinguisher, and selects the operation signal from the selected fire extinguisher. sent to the fire extinguisher.

If necessary, the fire receiver 400 may transmit the address information included in the fire caution information to the on-site inspector terminal when the fire caution information is provided from the fire information analyzer 200 . To this end, the fire receiver 400 may store the contact information of the on-site inspector terminal for each address information, and the fire receiver 400 addresses the on-site inspector terminal matching the address information of the fire caution information as the fire caution information is received. Inspection request information including information can be transmitted.

As described above, in the present invention, the fire information analyzer 200 or the fire receiver 400 may be configured to transmit the inspection request information to the on-site inspector terminal.

In addition, in the fire receiver 400, a fire detector 100 capable of detecting two or more types of fire elements is installed in the same monitoring area, or two fire detectors 100 capable of detecting different fire elements are installed, respectively. In this case, when a fire occurrence signal for two types of fire elements having the same address information is received, an operation signal of the fire extinguisher is generated and transmitted to the fire extinguisher having the same address information.

Specifically, the fire receiver 400 generates an operation signal of a fire extinguisher when both the fire occurrence information for the first real-time measurement information and the second real-time measurement information having the same address information are received from the fire information analyzer 200, The operation signal is transmitted to the fire extinguisher having the address information matched with the address information included in the generation information.

This is to control the operation of the fire extinguisher by cross-verifying the real-time measurement information received from the fire detectors installed in the fire monitoring area.

In this way, when two or more intersections of real-time measurement information collected from the fire detector 100 are verified for each monitoring area, the occurrence of a fire can be accurately determined, thereby preventing malfunction of the fire extinguisher.

If necessary, the fire receiver 400 transmits the fire occurrence information for the first real-time measurement information and the second real-time measurement information having the same first address information from the fire information analyzer 200 to the first address information. It may be configured to transmit an operation signal to a fire extinguisher installed within a radius of 10 to 50 m of the first fire extinguisher as well as the matched first fire extinguisher. This is to prevent the fire from spreading from the monitoring area where the fire occurred to the neighboring monitoring area.

As such a fire receiver 400, an R-type receiver may be used. In other words, unlike the P-type receiver, which controls the fire extinguisher by ON/OFF, the R-type receiver can continuously monitor fire-related fire factors such as temperature and smoke concentration. Even if it is cut, you can manage so that the fire extinguisher does not work.

As a specific aspect, the fire receiver 400 according to the present invention may include a communication module and a control module.

The communication module is wired or wirelessly connected to the fire extinguisher and the first analog detector and the second analog detector to receive the first real-time measurement information transmitted from each first analog detector and provide it to the fire information analyzer 200, each Receives the second real-time measurement information transmitted from the second analog detector of the and provides it to the fire information analyzer 200, and transmits an operation signal to the fire extinguisher.

In addition, the communication module receives the fire occurrence information provided from the fire information analyzer 200 and provides it to the control module, and transmits the fire alarm signal provided from the control module to the fire alarm 300 .

If necessary, the communication module may be connected to the on-site inspector terminal through a communication network. Examples of such communication networks include closed networks such as local area networks (LANs) and wide area networks (WANs), and open networks such as the Internet, as well as code division multiple access (CDMA) and wideband code division multiple access (WCDMA). ), Global System For Mobile Communication (GSM), Long Term Evolution (LTE), Evolved Packet Core (EPC), Wireless Fidelity (Wi-Fi, Wireless Lan (WLAN)), etc. may be used.

When the fire occurrence information transmitted from the fire information analyzer 200 is received, the control module may control the fire alarm 300 to output a fire alarm and an evacuation route notification. To this end, the control module generates a first fire alarm signal as the fire occurrence information is received, and transmits the first fire alarm signal to a monitoring area alarm having the same address information as the address information of the fire occurrence information, and the central alarm also sent to

In addition, when the fire caution information transmitted from the fire information analyzer 200 is received, the control module generates a second fire alarm signal and transmits the second fire alarm signal to the central alarm.

If necessary, the control module stores the address information of each fire extinguisher, and sends an operation signal not only to the fire extinguisher having address information matching the address information of the monitoring area where the fire occurred, but also to the fire extinguisher installed within a radius of 10 to 50 m of the fire extinguisher. may be configured to transmit. This is to prevent the fire from spreading from the monitoring area where the fire occurred to the neighboring monitoring area.

In addition, the control module analyzes the fire occurrence information to classify the fire occurrence information having the same address information, and if there are two or more fire occurrence information including different source information, it selects a fire extinguisher matching the address information and selects a fire extinguisher Generates an operation signal of, and transmits the operation signal to the selected fire extinguisher.

As described above, according to the present invention, it is possible to determine whether a fire has occurred by mutually analyzing the real-time measurement information transmitted from the fire detector 100 . That is, the control module outputs a fire signal when it is determined that two or more measured values of the fire elements are fire occurrence through real-time correction.

When it is analyzed that a fire has occurred in the first monitoring area through the analysis of the address information included in the fire occurrence information, the control module may generate an operation signal of the fire extinguishing equipment and transmit it to the fire extinguishing equipment installed in the first monitoring area. .
