If the result is larger than the threshold value, the information of the event analysis result is provided to each slave gas detection device An IOT-based traditional market that can prevent fire escalation by operating a fire hydrant through a gas-generated slave gas sensing device to perform an initial fire suppression and providing a fire alarm through the remaining slave gas sensing devices. ≪ / RTI >

Traditional markets and underground shopping malls can be seen as energy dense areas where several gas appliances or electric devices are installed in a narrow area.

In such an energy-dense region, a simple failure in one device can cause serious problems in the heterogeneous device, leading to an accident.

In addition, when a failure occurs in an energy-intensive area in which an electric device does not lead to a serious accident, it sometimes occurs in an adjacent energy-intensive area even if an accident does not occur in the energy-denied area .

However, at present, such an integrated safety management system has become necessary since an apparatus or system for managing the safety of gas devices or electric devices is not installed in such an energy dense region.

In the last five years (2013 ~ 2017), there are about 50 fires in the traditional market, and the damage is significant. In the case of fire in the traditional market, it is highly likely to suffer great damage due to aged facilities, And it is difficult to effectively suppress the fire because the fire truck can not enter the market due to the narrow market passage even after the fire occurs.

The characteristic of the traditional market is that each shop of merchants is directly next to each other, and it is common to display merchandise in such a way that a car passes in front of stores.

And, in the case of the facility state, the wiring of the distribution board is not well organized, and most of the wires that are exposed to the outside are still considerable.

In addition, since the aged wires need to be replaced by individuals, it is extremely vulnerable to the occurrence of the fire by the aged wires. However, there is a problem that the fire can not be effectively suppressed.

In order to overcome the above-mentioned problem, the prior art is to block the overcurrent. This is because even if the overcurrent flows, the environment of the cable may be different depending on the external temperature, humidity and the electric wire room, And installation and replacement costs are also high, so it is difficult to introduce them in reality.

Therefore, it is necessary to construct a system that can detect signs and effectively prevent fire before the occurrence of a fire while being cheap. In the present invention, a slave gas sensing device is configured for each booth in each traditional market, When the generated gas or organic compound (VOC) is detected, the master fire prediction apparatus obtains a plurality of gas detection information through wireless communication and compares it with a critical slope value of the gas concentration for each gas type, By providing the event analysis result information to the sensing device, the fire alarm is operated through the slave gas sensing device in which the gas is generated to perform the initial fire suppression, and the fire alarm is provided through the remaining slave gas sensing devices. IOT-based conventional fire prevention system that can prevent fire The.

At this time, the slave gas sensing device (100)

And is formed in an electric distribution board (10) or a distribution board that is installed for each store in each traditional market.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of an IOT-based traditional market fire prevention system according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall configuration diagram of an IOT-based traditional market fire prevention system according to a first embodiment of the present invention.

As shown in FIG. 1, the IOT-based traditional market fire prevention system according to the first embodiment of the present invention includes at least one slave gas sensing device 100 and a master fire prediction device 200 .

In the case of the traditional market, a switchboard is installed in a plurality of places in a traditional market to supply power to each store, and a switchboard is installed in each store to receive power from the switchboard.

The slave gas sensing apparatuses 100A, 100B, 100C, 100D, 100E, ..., 100N of the present invention are constituted in the switchboard or the distribution board installed in the traditional market, The prediction apparatus 200 exchanges information with each other through communication.

At this time, RF communication is applied to the communication between the master fire prediction apparatus 200 and the slave gas sensing apparatus 100 of at least one (100A to 100N) installed on the distribution board or the distribution board, which is preferable.

Of course, Wi-Fi communication can be used, but due to the characteristics of the traditional market, Wi-Fi penetration is low, so RF communication is applied.

In addition, the master fire prediction apparatus 200 of the present invention extracts a plurality of pieces of gas detection information included in the gas detection information for event analysis, when acquiring event detection gas detection information from a slave gas detection apparatus The slope value of the gas concentration is calculated for each gas type and compared with the critical slope value of the gas concentration for each gas type.

At this time, as a result of the comparison, if the number of slopes of the gas concentration exceeding the threshold slope value for each gas type and exceeding the threshold slope value preset in advance, which is the event determination condition information, or the slope value of the gas concentration exceeding the critical slope value When the number information of the VOC gas sensor is violated, unique ID information included in the gas detection information for event analysis is extracted to generate event analysis result information including the unique ID information, and is generated by at least one slave gas sensing device Event analysis result information.

Accordingly, in the case of the slave gas sensing apparatus having the unique ID information, the fire hydrant is operated to prevent the fire from occurring. At the same time, the fire alarm information is provided to the slave fire alarm unit 160, .

The remaining slave gas sensing devices provide fire alarm information through the slave fire alarm unit 160 and output alarm information.

For example, if the gas detection information for event analysis is acquired from the slave gas sensing device of '100A', the fire alarm is operated in the case of the '100A' slave gas sensing device to prevent the occurrence of fire , And '100N', '100C', '100D', '100E', ... '100N' at the same time, fire alarm information is provided through the slave fire alarm unit 160, .

As a result, according to the present invention, various gas generated just before a fire is detected in a complicated switchboard and a power line formed in a distribution board to supply power to each store in a traditional market by the above operation, So that it is possible to prevent the spread of the fire.

More specifically, in the early stage of a fire, electric wires formed in the switchboard and the distribution panel start to ignite by an arc, and the ignition is continued, resulting in a serious fire.

The present invention is characterized in that various kinds of noxious gas generated at the time of initial ignition of an electric wire or the like formed in an electric distribution board and a distribution board are detected and the fire is suppressed at the beginning before it is led to a full fire.

The components and operation of the slave gas sensing apparatus 100 according to the first embodiment will now be described in detail with reference to FIG.

2 is a block diagram of a slave gas sensing apparatus 100 of an IOT-based traditional market fire prevention system according to the first embodiment of the present invention.

2, the slave gas sensing apparatus 100 includes a VOC gas sensor array 110, a slave memory unit 120, a slave wireless communication unit 130, a slave digestive fluid injection command execution unit 140 A fire hydrant 150, a slave fire alarm unit 160, an alarm output device 170, and a slave control unit 180.

The VOC gas sensor array 110 may include a plurality of VOC gas sensors for detecting gas or organic compounds (VOC) generated during ignition in a wire.

Generally, in the case of the traditional market fire, the ignition starts on the electric wires in the switchboard or the panel board. When the electric wires are ignited, the electric wires are burnt by the heat and the chemicals are induced into the air.

Accordingly, in the present invention, the slave gas sensing device 100 is formed in an electric or electric distribution panel installed in each traditional market. Accordingly, when a fire occurs in the electric distribution panel or the distribution panel, .

Specifically, in the conventional fire prevention system, there is a disadvantage that it is difficult to detect a fire sign to use the gas sensor simply.

It is because of the nature of the gas that it is difficult to pinpoint the signs of the fire when the environment is well controlled and the environment is not controlled, such as by diffusion into the air and the inflow of outside air.

Accordingly, in the present invention, a slave gas sensing device is constructed in an enclosed space called an electric distribution board (10) or a distribution panel, thereby enhancing the sensing efficiency of the gas sensors in a closed space.

In addition, analyzing the gas concentration itself provides a system that can operate in various environments by analyzing the gradient change, which is the concentration change, rather than the concentration analysis, because there is a difference in concentration depending on the material and humidity of the wire.

At this time, the VOC gas sensor array 110 of the present invention,

A first VOC gas sensor 111 for detecting NOx, NH3, NOx, alcohol, benzene, smoke and CO ₂ ; a second VOC gas sensor 112 for detecting LPG, propane and H ₂ ; A first VOC gas sensor group 110A including a third VOC gas sensor 113 for detecting the first VOC gas sensor 113,

a fifth VOC gas sensor 115 for detecting CH4, LNG, and natural gas, and a sixth VOC gas sensor 116 for detecting LPG, natural gas, and town gas. A seventh VOC gas sensor 117 for detecting LPG, iso-butane, propane and LNG, an eighth VOC gas sensor 118 for detecting CO and a ninth VOC gas sensor 119 for detecting H ₂ And a second VOC gas sensor group including at least one VOC gas sensor group including at least one VOC gas sensor group.

That is, in the case of a VOC gas sensor, a gas sensor capable of detecting the presence or absence of a chemical substance ranging from a gaseous compound to a metal compound should be introduced.

Accordingly, a first VOC gas sensor 111 for detecting NH 3, NO x, alcohol, benzene, smoke, and CO ₂ , a second VOC gas sensor 112 for detecting LPG, propane, and H ₂ , , and a third VOC gas sensor 113 for sensing propane.

All VOC gas sensors were used, and as a result, all of the nine VOC gas sensors were able to detect gas generated from the melted wire just before the fire occurred.

However, the VOC gas sensors capable of satisfying both the reasonable price and the reliability, although it is possible to introduce all of the nine VOC gas sensors, were selected as the first VOC gas sensor group 110A.

As shown in FIG. 5, the first VOC gas sensor 111 is shown in purple, the second VOC gas sensor 112 is shown in green, the third VOC gas sensor 113 is shown in red, It can be seen that the slope of the graph of the three gas sensors tends to be abrupt before actual fire.

Therefore, in the present invention, the first VOC gas sensor group 110A is basically configured.

At this time, alcohol, CO ₂ , propene, hydrogen, CO, methane gas can be detected through the gas sensor constituting the first VOC gas sensor group 110A. In the gas components, These are the most common components.

However, if necessary, a fourth VOC gas sensor 114 for detecting alcohol, benzene, CH4, LNG, a fifth VOC gas sensor 115 for detecting natural gas, LPG, natural gas, the 6VOC gas sensor (116), LPG, iso- butane, propane, the 7VOC gas sensor 117 for sensing the LNG, the 8VOC gas sensor 118 for detecting CO, H ₂ for detecting the Town gas The second VOC gas sensor group 110B including the ninth VOC gas sensor 119 for detecting the second VOC gas sensor group.

As a result, at least one of the first VOC gas sensor group 110A and the second VOC gas sensor group 110B is installed in the present invention.

The slave memory unit 120 stores unique ID information and a plurality of gas sensing information sensed from the VOC gas sensor array.

For example, in the case of a slave gas sensor of '100A', unique ID information such as' ID- # 100A ',' # 1 VOC-30 ',' # 2 VOC-25 ',' # 3 VOC- And stores sensing information.

When the slave controller 180 acquires a plurality of pieces of gas detection information from the VOC gas sensor array 110, the slave controller 180 generates gas detection information for event analysis by matching the unique ID information and the plurality of pieces of gas detection information, And provides gas analysis information for event analysis to the slave wireless communication unit 130.

For example, when a plurality of gas sensing information is acquired from the VOC gas sensor array 110, the ID information is stored in the slave memory unit 120. At this time, the unique ID information 'ID- # 100A' And the event analysis gas such as' request_ID- # 100A_ # 1 VOC-30_ # 2 VOC-25 # 3 VOC-35 'by matching detection information' # 1 VOC-30 ',' # 2 VOC-25 ', and' # 3 VOC- Generates the detection information, and provides it to the slave wireless communication unit 130 to request an event analysis result.

When acquiring event analysis result information transmitted from the slave wireless communication unit 130 from the master fire prediction apparatus 200, the unique ID information included in the event analysis result information and the unique ID information stored in the slave memory unit 120 If the ID information matches, the fire extinguishing agent injection command execution unit 140 provides the fire extinguisher injection command information to operate the fire hydrant. At the same time, the slave fire alarm unit 160 To provide fire alarm information and output alarm information.

For example, when acquiring the event analysis result information 'result_ID- # 100A_ # action_2018 / 3/3/10', 'ID- # 100A' which is the unique ID information included in the event analysis result information, ID-# 100A 'stored in the slave fire extinguisher command execution unit 140. Since the unique ID information is identical, the fire extinguisher injection command information is provided to the slave fire extinguishing liquid injection command execution unit 140 to operate the fire hydrant, And outputs the alarm information.

If the unique ID information does not match, the slave fire alarm unit 160 provides fire alarm information and outputs alarm information.

For example, in the case of the slave gas sensing device of '100B', the unique ID information 'ID- # 100B' is stored. At this time, the unique ID information 'ID- # 100A ID-# 100B 'stored in the slave memory unit, the fire alarm information is provided to the slave fire alarm unit 160 without operating the fire hydrant because the unique ID information does not match, .

The slave wireless communication unit 130 transmits the event analysis gas detection information provided from the slave control unit 180 to the master fire prediction apparatus 200 and outputs the event analysis result information transmitted from the master fire prediction apparatus 200 And provides it to the slave control unit 180.

For example, it is possible to transmit the event detection gas detection information 'request_ID- # 100A_ # 1 VOC-30_ # 2 VOC-25_ # 3 VOC-35' to the master fire prediction apparatus 200, And obtains the transmitted event analysis result information 'result_ID- # 100A_ # action_2018 / 3/3/10' and provides it to the slave control unit 180.

The wireless communication method preferably uses an RF communication method. However, the wireless communication method may use a Wi-Fi method or a Zigbee communication method if necessary. It is obvious that the communication method of the present invention can be applied.

The slave fire hydrant injection command execution unit 140 provides an operation signal to the fire hydrant 150 when obtaining the fire hydrant injection command information from the slave control unit 180. [

That is, when the fire extinguisher 150 obtains the fire extinguishing command information '#action' from the slave controller 180, the fire extinguisher 150 provides an operation signal from the slave fire extinguisher injection command execution unit 140 In case of acquisition, the digestion liquid is sprayed around the electric wire.

In the case of the fire hydrant described above, preferably, a fire hydrant for injecting a carbon dioxide component is used, and it can be sufficiently extinguished because it is installed inside the switchboard or the distribution board.

When the slave fire alarm unit 160 obtains the fire alarm information from the slave control unit 180, the slave fire alarm unit 160 provides an alarm signal to the alarm output unit 170. In the slave control unit, The alarm output device 170 outputs the alarm sound to the surroundings when acquiring the alarm signal from the slave fire alarm unit 160. [

For example, the alarm output device may be a buzzer generating device for generating a buzzer sound or a speaker device for outputting alarm sound information, and a beacon may be additionally provided if necessary.

Therefore, a buzzer is output through the buzzer generating device, and an alarm sound is output through the speaker device, thereby informing that a fire has occurred in an audible manner, and notifying that a fire is visually generated through a warning light.

By this, it is possible to judge the current situation by preventing the second confirmation of the fire and informing the merchants that the fire has occurred.

Next, the components and operation of the slave gas sensing apparatus 100 according to the first embodiment will be described in detail with reference to FIG.

3 is a block diagram of a slave controller 180 of the IOT-based traditional market fire prevention system according to the first embodiment of the present invention.

3, the slave controller 180 includes an event analysis gas detection information generation module 181, a unique ID information comparison module 182, a fire hydrant operation module 183, a fire alarm operation module 184 ).

More specifically, the event analysis gas detection information generation module 181 extracts unique ID information stored in the slave memory unit 120 when acquiring a plurality of gas detection information from the VOC gas sensor array 110 And generates gas sensing information for event analysis by matching the extracted unique ID information with the plurality of gas sensing information and provides the generated gas sensing information for event analysis to the slave wireless communication unit 130.

For example, when acquiring a plurality of pieces of gas detection information from the VOC gas sensor array 110, the unique ID information 'ID- # 100A' stored in the slave memory unit 120 and the plurality of gas detection information '# - # 1VOC-30_ # 2VOC-25 # 3VOC-35 'by matching' 1VOC-30 ',' # 2VOC-25 'and' # 3VOC-35 ' And provides it to the slave wireless communication unit 130 to request the master fire prediction apparatus 200 for event analysis result information.

When the slave wireless communication unit 130 acquires the event analysis result information provided from the master fire prediction apparatus 200, the unique ID information comparison module 182 compares the unique ID information included in the corresponding event analysis result information with the slave The unique ID information stored in the memory unit 120 is compared.

For example, when the event analysis result information 'result_ID- # 100A_ # action_2018 / 3/3/10' transmitted from the master fire prediction apparatus 200 is acquired, the unique ID information 'ID- # 100A At the same time, the unique ID information stored in the slave memory unit 120 is extracted, and the unique ID information is compared.

Here, if the unique ID information matches, the fire alarm operation module 183 provides a result of the unique ID information comparison because the fire alarm is an instruction to operate the fire alarm configured in the slave gas sensing device 100.

At this time, the fire hydrant operation module 183 provides the fire extinguisher injection command information to the slave fire extinguishing agent injection command execution unit 140 when the unique ID information matches the unique ID information by the unique ID information comparison module 182 The fire hydrant 150 is operated, and at the same time, fire alarm information is provided to the slave fire alarm unit 160 to output alarm information.

For example, when the fire extinguisher 150 is operated, the slaving fire alarm unit 160 provides fire alarm information to the slaving fire injection command execution unit 140, And outputs alarm information, that is, an alarm sound.

That is, the slave fire alarm unit 160 provides fire alarm information through the fire alarm operation module 184 to output alarm information.

Meanwhile, when the unique ID information is not identical as a result of the unique ID information comparison by the unique ID information comparison module 182, the fire alarm operation module 184 provides fire alarm information to the slave fire alarm unit 160 And outputs the alarm information.

For example, when the unique ID information included in the event analysis result information transmitted from the master fire prediction apparatus 200 is 'ID- # 100A', a slave gas having unique ID information of 'ID- # 100B' The sensing apparatus 100 does not need to operate the fire hydrant because the unique ID information does not coincide with each other, but the fire alarm information is provided to inform that the fire has occurred from the slave gas sensing apparatus having the ID-# 100A will be.

Therefore, in-store merchants located at a distance from the place where the fire occurred can confirm this and quickly evacuate.

In summary, if the unique ID information provided from the master fire prediction unit matches the unique ID information stored in the slave memory unit 120, the fire alarm operation module 184 provides fire alarm information to the fire hydrant while simultaneously providing fire alarm information If the unique ID information does not match, only fire alarm information is provided.

Next, the components and operation of the master fire prediction apparatus 200 according to the first embodiment will be described in detail with reference to FIG.

4 is a block diagram of a master fire prediction apparatus 200 for an IOT-based traditional market fire extinction prevention system according to the first embodiment of the present invention.

4, the master fire prediction apparatus 200 includes a threshold type threshold value memory unit 210, a master wireless communication unit 220, a gas concentration gradient value calculation unit 230 for each gas type, A generation determining unit 240, and an event analysis result information generating unit 250.

Specifically, the gas type threshold slope value memory 210 stores threshold slope values for each gas type and event determination condition information.

The gas type threshold gradient value are, for example, 'NH3 - 1.5' storage the gas type threshold tilt value, such as _{- '2.0 CO 2', '} NOx - 1.0', 'benzene - - 1.0', 'smoke 1.5', .

The event determination condition information indicates the number of slope values of the gas concentration exceeding the threshold slope value. For example, when the number of slope values of the gas concentration exceeding the critical slope value is 1, 2, 3, ..., N, and so on, and stores the set number.

The event determination condition information is information on the number of VOC gas sensors having a slope of the gas concentration exceeding the threshold slope value. For example, if the first VOC gas sensor to the third VOC gas sensor are configured, The first VOC gas sensor and the second VOC gas sensor generate an event when they have a slope value of the gas concentration exceeding the critical slope value.

The master wireless communication unit 220 receives the gas analysis information for event analysis transmitted from at least one slave gas sensing apparatus 100 and provides the gas concentration information to the gas concentration gradient calculation unit 230 for each gas type, And provides the event analysis result information provided from the event analysis result information generation unit 250 to at least one slave gas sensing device 100. [

At this time, the RF communication method is preferably used in the present invention, but it is obvious that a Wi-Fi communication method, a Zigbee communication method, and an RS 232C communication method can be used as needed.

The gas concentration-based gas concentration gradient value calculation unit 230 includes the gas concentration-based gas concentration gradient value calculation unit 230 and the gas concentration-based gas concentration gradient value calculation unit 230. The gas concentration- And the slope value of the gas concentration is calculated for each gas type.

For example, as shown in FIG. 6, the gas concentration of NH3 detected at 10:00 am on March 3, 2018 from the first VOC gas sensor 111 is detected at 10:01 am on March 3, 2018 The calculated slope value was 'NH3 - 1.6', and the gas concentration of NOx detected at 10:00 am on March 3, 2018 and the concentration of NOx detected on March 3, 2018 The slope value between the gas concentration of NOx detected at 10:01 am is calculated, and the calculated slope value is 'NOx - 1.6'.

In the case of FIG. 6, a red solid line represents a point where a fire occurs, and a blue solid line represents a portion where a slope of a gas concentration before a fire suddenly increases.

At this time, the event analysis result generation determining unit 240 determines the event analysis result generation determining unit 240 based on the slope values of the gas concentrations for each gas type calculated from the gas concentration gradient value calculator 230 for each gas type, And compares the critical slope value for each gas type.

For example, when the slope value of NH3 detected from the first VOC gas sensor 111 is 'NH3 -1.6' and the threshold slope value of NH3 'NH3 -1.5' is compared from the threshold slope value memory unit 210 for each gas type .

At this time, when the slope value of the gas concentration for each gas type exceeds the threshold slope value for each gas type and at the same time, the event determination condition information stored in the threshold slope value memory unit for each gas type is violated, (Not shown).

For example, if the slope value of NH 3 is 'NH 3 -1.6' and the critical slope value of NH 3 is 'NH 3 -1.5', the threshold slope value is exceeded, so that the event determination condition information stored in the threshold slope value memory unit for each gas type It is judged whether or not it is contravened.

For example, if the number of slope values of the gas concentration exceeding the critical slope value is set to two or more when the event determination condition information is the number information of the slope value of the gas concentration exceeding the threshold slope value, The slope value of the NOx is 'NH3 -1.6', the slope value of the NH3 is 'NH3 -1.5', the slope value of the NOx is 'NOx-1.6' and the slope value of the NOx is 'NOx-1.0' The event analysis result information generation unit 250 provides the event analysis result generation information to the event analysis result information generation unit 250 because it violates the event determination condition information because it exceeds the threshold slope value.

The event determination condition information may be information on the number of VOC gas sensors having a gradient of gas concentration exceeding a threshold slope value.

For example, the number of VOC gas sensors having a slope value of the gas concentration exceeding the critical slope value is set to two or more, and the first VOC gas sensor 111, the second VOC gas sensor 112, When the first VOC gas sensor 111 is composed of the first VOC gas sensor 111 and the second VOC gas sensor 112 is composed of the first VOC gas sensor 111 and the second VOC gas sensor 112, the NH 3 detected by the first VOC gas sensor 111 is determined to be a slope value of the gas concentration exceeding the threshold slope value, If it is determined that the slope value of the gas concentration exceeds the slope value, the number of the VOC gas sensors having the slope value of the gas concentration exceeding the threshold slope value is two, which is contrary to the event judgment condition information. And provides the analysis result information to the information generating unit 250.

As described above, at least any one or more of the information of the number of the slope values of the gas concentration whose event judgment condition information exceeds the threshold slope value, and the information of the number of the VOC gas sensors having the slope value of the gas concentration exceeding the threshold slope value Is to set the sensitivity of the gas sensing.

For example, when the sensitivity is 'high', the number of slope values of the gas concentration exceeding the critical slope value is 3 or more, and when the sensitivity is 'middle', the slope value of the gas concentration exceeds the critical slope value The number of slope values of the gas concentration exceeding the critical slope value can be set to one or more when the number of the slopes is two or more and the sensitivity is low.

When the sensitivity is 'high', the number of VOC gas sensors having a slope of the gas concentration exceeding the critical slope value is 3 or more, and when the sensitivity is 'middle', the gas concentration exceeds the critical slope value It is possible to set the number of VOC gas sensors having a slope value of 2 or more and the sensitivity of the VOC gas sensor having a slope value of a gas concentration exceeding a critical slope value to 1 or more when the sensitivity is 'low'.

As described above, in order to set the sensitivity, the event analysis result generation and determination unit 240 determines whether or not the VOC gas sensor has a slope value of the gas concentration exceeding the threshold slope value or the number of slope values of the gas concentration exceeding the threshold slope value And a sensitivity setting unit for setting the number of pixels.

The event analysis result information generation unit 250 extracts unique ID information included in the event analysis gas detection information when acquiring event analysis result generation request information from the event analysis result generation determination unit 240 .

For example, it extracts the unique ID information included in the gas detection information for event analysis 'ID- # 100A'.

Then, event analysis result information including the extracted unique ID information is generated and provided to the master wireless communication unit.

For example, the event analysis result information includes text information indicating that a fire occurrence is predicted, date information, and unique ID information of the slave gas sensing device.

That is, event analysis result information 'result_ID- # 100A_ # action_2018 / 3/3/10' is generated and provided to the master wireless communication unit.

In this case, the user terminal 3000 receives monitoring information from the monitoring server 2000 or the master fire prediction device 200.

In addition, the monitoring application 3500 may display the provided monitoring information on the screen of the user terminal 3000,

The monitoring information includes:

The unique ID information of the slave gas sensing apparatus 100 providing the gas sensing information for event analysis, the gas concentration information for each gas type, the slope value of the gas concentration for each gas type exceeding the critical slope value for each gas type, And the fire hydrant operation result information provided from the slave fire hydrant injection command execution unit 140 of the slave gas sensing apparatus.

In general, monitoring information is obtained from the master fire prediction apparatus 200 through the monitoring server 2000 according to a manual for fire detection.

In addition, monitoring information is provided from the monitoring server 2000 or the master fire prediction apparatus 200 by additionally configuring the user terminal 3000.

The user terminal may be a manager that manages a fire in a traditional market, or may be a merchant who operates each store.

In order to acquire the monitoring information, a user terminal 3000 capable of network communication with the monitoring server 2000 or the master fire prediction device 200 is configured, and a monitoring app 3500 is mounted on the user terminal.

Accordingly, the user terminal 3000 that acquires the monitoring information from the monitoring server 2000 or the master fire prediction device 200 outputs the monitoring information acquired through the installed monitoring application 3500 to the screen.

That is, when the monitoring application 3500 is executed, a communication network is formed between the user terminal 3000 and the monitoring server 2000 or the master fire prediction device 200, and the monitoring server 2000 or the master fire prediction device 200 The monitoring information is obtained and outputted to the screen.

In this case, when the user terminal desires to acquire the monitoring information from the monitoring server 2000 or the master fire prediction device 200, the user terminal and the monitoring server 2000 or the master fire prediction device 200 are connected to a general mobile communication network If the user terminal desires to acquire the monitoring information from the general fire control room, the user terminal and the monitoring server of the general fire control room are connected to the in-house network or other wireless communication network.

The monitoring information includes unique ID information of the slave gas sensing apparatus 100 providing the gas sensing information for the event analysis, gas concentration information of each gas type, a slope value of the gas concentration for each gas type exceeding the critical slope value for each gas type, Event analysis result information, and fire hydrant operation result information provided from the slave fire hydrant injection command execution unit 140 of the slave gas sensing apparatus.

For example, if the unique ID information 'ID- # 100A' of the slave gas sensing apparatus 100, 'NH3 -20', 'NOx-40' 'NH3-1.6', 'NOx-1.6', 'event_ID- # 100A_ # action_2018 / 3/3/10' which is the event analysis result information, and the slave gas sensor ID-# 100A_clear ', which is the fire hydrant operation result information provided from the slave fire-fighting injection command execution unit 140, and provides information to the user terminal, the monitoring application 3500 ) Is driven to output the information on the screen of the user terminal.

Meanwhile, in order to provide the fire alarm operation result information to the monitoring server 2000 or the master fire predicting device 200, the slave fire hydrant injection command execution unit 140 obtains fire hydrant operation result information indicating that the fire was ejected from the fire hydrant And provides the obtained fire hydrant operation result information to the master fire predicting device or the monitoring server 2000.
