Referring to FIG. 2, first, in step S201, a signal including field data generated through the sensor 100 and information on the area where the sensor is located is transmitted through an RF communication module installed in the sensor 100 to a signal of a disaster communication frequency band. may be transmitted to the gateway 200.

Specifically, the sensor 100 may include an embedded system, is normally in a sleep mode, and may generate field data including a sensor value when a preset condition is satisfied by an input system. In addition, when field data is generated, the sensor 100 converts a signal including the generated field data and information of the area where the sensor is located into a signal of a disaster communication frequency band through an RF communication module installed in the sensor 100 to the gateway 200. ) can be transmitted. Here, the disaster communication frequency band may include 447 MHz and 700 MHz bands, and may include other UHF bands of 300 to 3,000 MHz.

At this time, the sensor 100 may transmit a signal of a disaster communication frequency band in the process of transmitting to the gateway 200, but is not limited thereto, and may be transmitted using a different frequency.

Here, the information of the region where the sensor is located may include location data pre-stored in the sensor to check the remaining battery capacity, and the information of the region where the sensor is located may include the serial number of the sensor. In addition, the management server 300 may transmit and receive battery remaining amount data from the sensor 100 at predetermined intervals in order to check the remaining battery amount of the sensor. It can be confirmed that there is In addition, the management server 300 may test the corresponding sensor to check the remaining battery capacity of the sensor, and may check whether the sensor has errors or defects through the test. In this case, the test may be a communication test, a function test, or a peripheral communication equipment test. In addition, the management server 300 may check defects and errors of the sensor by dispatching a sensor manager to check the remaining battery capacity of the sensor.

In step S202, the signal transmitted to the gateway 200 may be transmitted to the control server 300 through a router.

Specifically, the control server 300 may transmit a signal request to the gateway 200 at each preset period, and the gateway 200 sends the sensor 100 in response to the signal request received from the control server 300 at each period. Through this, a signal including battery remaining amount data, transmitted field data, and information on a region where a sensor is located may be transmitted to the control server 300 through a router. Here, the router is a wireless router that provides an Internet connection using a cellular network (LTE), and although the router is not described in the text, it can perform tasks normally performed by routers.

In step S203, the control server 300 analyzes the field data, reflects the field data in real time to the dashboard built in the district office or management center, and performs disaster management and disaster notification. At this time, the control server 300 may communicate with at least one server of the district office and the management center through wired or wireless communication.

3 is a flowchart illustrating a process of arranging a safety manager for a disaster area based on the type of sensor and the number of sensors generating data of a standard or higher according to an embodiment.

Referring to FIG. 3 , first, in step S301, the control server 300 may check the type of sensor that transmits a signal among sensors installed in an area.

Specifically, the control server 300 checks the type of sensor that transmits the signal based on field data generated from the sensor 100 installed in the area, and determines whether a signal from any sensor among a fire sensor, a gas sensor, and a submersion sensor is detected. you can check if it was created

In step S302, the control server 300 may check whether there is one type of sensor that has transmitted a signal among sensors installed in the area.

If it is confirmed in step S302 that the type of sensor transmitting the signal is one among the sensors installed in the region, in step S303, the control server 300 may generate a disaster complexity of the region as low.

Specifically, the control server 300 checks the type of sensor that transmits the signal based on the field data generated from the sensor 100 installed in the area, and if it is confirmed that the type of sensor is one, the disaster complex in the area You can create a low degree.

For example, if the type of sensor that transmits a signal among the sensors installed in the area is confirmed only by the gas sensor, the control server 300 determines the type of sensor based on the field data generated from the sensor 100 installed in the area. Confirm that it is a single sensor, and create a disaster complexity of the area as low.

If it is confirmed in step S302 that there is not one but at least two types of sensors that have transmitted signals among the sensors installed in the region, in step S304, the control server 300 may generate high disaster complexity of the region.

Specifically, the control server 300 checks the type of sensor that transmits the signal based on the field data generated from the sensor 100 installed in the area, and if it is confirmed that the type of sensor is not one but at least two types , the disaster complexity of the region can be created as high.

For example, if the type of sensor that transmits a signal among the sensors installed in the region is identified as a gas sensor and a fire sensor, the control server 300 determines the number of sensors based on field data generated from the sensor 100 installed in the region. You can confirm that there are two types of gas sensor and fire sensor, and create a disaster complexity of the area as high.

When the disaster complexity of the region is generated as high in step S304, in step S305, the control server 300 may determine whether the number of sensors that have transmitted data equal to or greater than the reference number is less than the reference number. Here, the reference number is a preset value and may vary according to embodiments. In addition, data above the standard may vary depending on the type of sensor and may vary depending on the sensor value.

Specifically, the sensor 100 may be a composite detection sensor, and may have an embedded system.

The fire sensor includes a composite detection function, and can perform partial operation or full operation through the composite detection function and sensor value. If all is working, it can be seen that there is a fire and that the fire is serious. In addition, when the fire sensor is partially operated to generate field data, the control server 300 may determine that data higher than the standard is not generated, and when the fire sensor is fully operated to generate field data, the control server ( 300) may determine that more than standard data has been generated. Here, information on whether the fire sensor partially operates to generate field data or whether all fire sensors operate to generate field data may be included in the field data generated from the fire sensor.

That is, data above the standard corresponding to the fire sensor may be all field data generated through operation, and the control server 300 generates field data by operating all the fire sensors based on the field data generated by the fire sensor. and if it is confirmed that the field data generated by all operations has been transmitted, it can be determined that the fire sensor has transmitted field data above the standard, and the control server 300 based on the field data generated by the fire sensor, the fire sensor is partially If it is confirmed that the field data was generated by operating and the field data generated by partial operation was transmitted, it can be determined that the fire sensor did not transmit field data beyond the standard.

The submersion sensor can generate field data by dividing the steps into step 1 and step 2 according to the sensor value. If the field data were generated in step 2, it would be known that it was completely submerged. In addition, when the submersion sensor generates field data in the first step, the control server 300 may determine that data higher than the standard is not generated, and when the submersion sensor generates the field data in the second step, the control server 300 ) can be determined to have generated more than standard data. Here, information on whether the submersion sensor generated field data in one step or the submersion sensor generated field data in two steps may be included in the field data generated from the submersion sensor. Meanwhile, the control server 300 may determine the severity of the damage by calculating the time from step 1 to step 2 generated by the submersion sensor, that is, the time when the received data changes.

That is, the standard or higher data corresponding to the submersion sensor may be field data generated in two steps, and the control server 300 based on the field data generated by the submersion sensor, the submersion sensor generated field data in two steps, , If it is confirmed that the field data generated in step 2 has been transmitted, it can be determined that the submersion sensor has transmitted field data of a standard or higher, and the control server 300, based on the field data transmitted from the submersion sensor, If it is confirmed that the field data was generated in step 1 and the field data generated in step 1 was transmitted, it can be determined that the submersion sensor did not transmit field data beyond the standard.

The gas sensor can generate field data by dividing the stages into forecast, occurrence, urgency, and emergency according to the sensor value. If the field data is generated with , it can be known that the gas has leaked, and if the gas sensor has generated field data as an emergency, it can be known that the gas has leaked and is now urgent, and the gas sensor generates field data as an emergency. In one case, you know that gas has leaked and is now critical. In addition, when the gas sensor generates on-site data due to a forecast or occurrence, the control server 300 may determine that data higher than the standard is not generated, and when the gas sensor generates on-site data due to an emergency or emergency, the control server 300 (300) may determine that more than standard data has been generated. Here, information on whether the gas sensor generated field data as a forecast, generated field data, generated field data as an emergency, or generated field data as an emergency may be included in the field data generated from the gas sensor. . Meanwhile, the control server 300 may determine the severity of the damage by calculating the time from step 1 to step 2 generated by the submersion sensor, that is, the time when the received data changes.

That is, the standard or higher data corresponding to the gas sensor may be field data generated in an emergency or emergency, and the control server 300 generates field data in an emergency based on the field data generated by the gas sensor and , If it is confirmed that the field data generated in an emergency has been transmitted, it can be determined that the gas sensor has transmitted field data that exceeds the standard, and the control server 300 determines that the gas sensor is an emergency based on the field data generated by the gas sensor. If it is confirmed that the field data has been generated and the field data generated due to an emergency has been transmitted, it may be determined that the gas sensor has transmitted field data that exceeds the standard. In addition, the control server 300, based on the field data transmitted from the gas sensor, when it is confirmed that the gas sensor has generated field data as a forecast and has transmitted the field data generated as a forecast, the gas sensor generates field data that exceeds the standard. If it can be determined that it is not transmitted, and the control server 300 determines that the gas sensor has generated field data based on the field data transmitted from the gas sensor and has transmitted the field data generated by the occurrence, the gas sensor 300 It can be determined that did not transmit field data higher than the standard.

Specifically, the control server 300 may further determine the severity of a disaster in a region when the disaster complexity of the region is generated as high. The control server 300 has a sensor installed in the region to determine the severity of the disaster It is possible to determine whether the number of sensors generating data equal to or greater than the reference number is less than the reference number by checking the number of sensors that have transmitted data equal to or greater than the reference number.

If it is determined in step S305 that the number of sensors generating data equal to or greater than the reference number is less than the reference number, in step S306, the control server 300 may generate a local disaster severity as low.

Specifically, the control server 300 checks the type of sensor that transmits a signal among the sensors 100 installed in the area based on the field data generated from the sensor 100 installed in the area, and if at least two types of sensors are detected. If the type or more is confirmed, the disaster complexity of the region is generated as high, and if the disaster complexity of the region is generated as high, the number of sensors 100 installed in the region that generate data greater than or equal to the standard is greater than the standard number. When it is determined whether the number of sensors 100 installed in the region is small and the number of sensors generating data equal to or higher than the standard is small, the disaster severity of the corresponding region may be set to low. That is, the control server 300 has at least two types of sensors that transmit signals among the sensors 100 installed in the region, and the number of sensors that generate data equal to or higher than the standard among the sensors 100 installed in the region is the standard number. If it is determined that the number is less than that, the control server 300 may generate a disaster complexity of the corresponding region as high, and generate a disaster severity of the corresponding region as low.

For example, if the type of sensor that transmitted a signal among the sensors installed in the area is identified as a gas sensor or a fire sensor, and the number of sensors installed in the area that generated data above the standard is 1, and the standard number is 3 Based on the field data generated from sensors installed in the region, the control server 300 confirms that there are two types of sensors, a gas sensor and a fire sensor, and determines the number of sensors installed in the region that generate data greater than or equal to the standard. By confirming that 1 is less than the standard number of 3, the disaster complexity of the region can be created as high, and the disaster severity of the region can be created as low.

When it is determined in step S305 that the number of sensors generating data equal to or greater than the reference number is not less than the reference number, in step S307, the control server 300 may generate a local disaster severity as high.

Specifically, the control server 300 checks the type of sensor that transmits a signal among the sensors 100 installed in the area based on the field data generated from the sensor 100 installed in the area, and if at least two types of sensors are detected. If the type or more is confirmed, the disaster complexity of the region is generated as high, and if the disaster complexity of the region is generated as high, the number of sensors 100 installed in the region that generate data greater than or equal to the standard is greater than the standard number. If it is determined whether or not the number of sensors 100 installed in the region is not small and the number of sensors generating data equal to or higher than the standard is not small, the disaster severity of the region may be set to high. That is, the control server 300 has at least two types of sensors that transmit signals among the sensors 100 installed in the region, and the number of sensors that generate data equal to or higher than the standard among the sensors 100 installed in the region is the standard number. If it is determined that the number is not less than, the control server 300 may generate a disaster complexity of the corresponding region as high, and generate a disaster severity of the corresponding region as high.

For example, if the type of sensor that transmitted a signal is identified as a gas sensor or a fire sensor among sensors installed in the area, the number of sensors that generated data higher than the standard among sensors installed in the area is 10, and the standard number is 3 Based on the field data generated from sensors installed in the region, the control server 300 confirms that there are two types of sensors, a gas sensor and a fire sensor, and determines the number of sensors installed in the region that generate data greater than or equal to the standard. By confirming that 10 is more than the standard number of 3, the disaster complexity of the region can be created as high, and the disaster severity of the region can be created as high.

In step S308, the control server 300 may differently arrange the number of safety managers according to the disaster complexity and disaster severity of the region.

Specifically, the control server 300 may arrange the number of safety managers differently according to the disaster complexity of the region and the severity of the disaster in the region, and when it is confirmed that the region's disaster complexity is low, N safety managers may be placed. If the disaster complexity of the region is confirmed to be high and the disaster severity of the region is confirmed to be low, more M safety managers than N can be assigned. If confirmed, it is possible to assign L more safety managers than M.

In addition, the control server 300 may guide the evacuation of users at the site and transmit a notification to support the site to a terminal of a safety manager disposed in the area, that is, at the site. Here, the database provided in the control server 300 may match and store information on a region and a safety manager who manages the safety of the region. It can be a person or facility that manages the safety of other areas. In addition, the control server 300 may communicate with the terminal of the safety manager by wire or wireless.

In addition, the control server 300 can recognize the user's terminal included within a preset reference range with the corresponding sensor 100 through the sensor 100, and can transmit a notification requesting emergency preparation to the user's terminal. . Here, the preset reference range may vary according to embodiments, and may vary according to regional disaster complexity and regional disaster severity. Specifically, the reference range may be narrower as the disaster complexity of a region is lower, and the reference range may be wider as the disaster complexity of a region is higher. In addition, the standard range may be narrower as the severity of a disaster in a region is low, and the standard range may be wider as the severity of a disaster in a region is higher.

Due to this, the control server 300 may generate a disaster complexity of the site as high when it is confirmed that a complex accident such as fire, gas accident, flooding, etc. has occurred at the same time at the same site, and if the disaster complexity is high In addition, the number of safety managers to be deployed in the area can be selected by further checking the disaster severity of the site through the number of sensors that generated data above the standard.

Meanwhile, when the signal generated by the sensor 100 cannot be transmitted to the control server 300 through the gateway 200, the sensor 100 transmits the signal using the mesh network, and the control server 300 through the mesh network. ) can be transmitted as a signal.

In addition, the control server 300 considers the sensor 100 that cannot transmit signals using the mesh network and when it is determined that the gateway 200 that has failed to transmit signal information is located in a specific region, the information in the specific region A collection vehicle can be dispatched.

4 is a flowchart illustrating a process of receiving a signal through an information collection vehicle when the control server fails to receive a signal according to an embodiment.

Referring to FIG. 4 , first, in step S401, the control server 300 may check the region where the gateway 200 that has not received signal information during the reference time is located. Here, the reference period is a preset period and may vary according to embodiments.

Specifically, the control server 300 may obtain information on signals from the gateway 200 at preset intervals. Here, the information about the signal is when the gateway 200 receives the signal from the sensor 100, the information about the signal may be the signal received from the sensor 100, and the gateway 200 receives the signal from the sensor 100. If not received, information on the signal may be information indicating that the signal has not been received from the sensor 100 . Also, when the control server 300 does not receive signal information from the gateway 200 during the reference time, it may check the region where the corresponding gateway 200 is located.

That is, the control server 300 may receive information about a signal from the gateway 200 at preset intervals, check whether or not information about a signal is received during a reference period, and information about a signal during a reference period. If not received, the control server 300 may check the region where the gateway 200 is located in order to determine whether there is a problem in the operation of the gateway 200 due to a current disaster in the region including the gateway 200.

In step S402, the control server 300 may check whether the gateway 200 exists in a specific area.

Specifically, the control server 300 checks the region where the gateway 200 that has not received signal information during the reference time is located, and the gateway 200 that has not received signal information for the reference time is located in a specific region. You can check whether it exists or not.

That is, the control server 300 transmits signal information during the reference time to check whether the gateway 200, which has failed to transmit signal information to the control server 300, has a problem in operation due to a current disaster. It is possible to check whether the gateway 200 that failed to transmit to the control server 300 exists in a specific area.

If it is confirmed in step S402 that the gateway 200 that has not received signal information for the reference time exists in a specific area, in step S403, the control server 300 can check whether there is disaster-related information in the specific area. .

Specifically, when the control server 300 determines that the gateway 200 that has not received signal information for a reference time exists in a specific area, the control server 300 uses Twitter, Instagram, blog, cafe, disaster It is possible to check whether there is disaster-related information in a specific area through SNS or articles including reports, and computerized inquiry of related institutions. At this time, the control server 300 communicates with the website and the computer server including the SNS and articles by wire or wireless, and can access the website and the computer server, and the control server 300 connects to the website and sends the SNS to a specific area. It is possible to check whether there is disaster-related information related to , and the control server 300 may check whether there is disaster-related information related to a specific region by accessing a computer server of a related institution.

On the other hand, if the control server 300 determines that the gateway 200 that has not received information about the signal during the reference time does not exist in a specific area, it returns to step S501, and the control server 300 responds to the signal during the reference time. It is possible to check whether there is a gateway 200 that has not received signal information, and to check an area where the gateway 200 that has not received signal information for a reference time is located.

If it is confirmed that there is disaster-related information in a specific area in step S403, in step S504, the control server 300 may directly receive a signal of the disaster communication frequency band from the sensor 100 located in the specific area, and transmit the received signal to Information collection vehicles that can be transmitted to the control server 300 may be checked and dispatched to a specific area may be requested.

Specifically, when the control server 300 confirms that there is disaster-related information in a specific area, the control server 300 may directly receive a signal of the disaster communication frequency band from the sensor 100 located in the specific area, and the received Information on an information collection vehicle capable of transmitting a signal to the control server 300 may be obtained, and an dispatch request to dispatch to a specific area may be transmitted to the information collection vehicle. Here, the control server 300 may communicate with the information collection vehicle by wire or wireless.

On the other hand, if the control server 300 determines that there is no disaster-related information in a specific area, it returns to step S401, and the control server 300 determines whether there is a gateway 200 that has not received signal information during the reference time. and the area where the gateway 200 has not received signal information during the reference time is located.

That is, the control server 300 may directly receive a signal from the sensor 100 when it is confirmed that there is a problem in the operation of the gateway 200 due to a disaster in the area including the current gateway 200, and the received signal A signal may be received through the information collection vehicle instead of the gateway 200 by checking an information collection vehicle capable of transmitting to the control server 300 .

At this time, the sensor 100 may obtain information on whether the control server 300 receives the signal transmitted from the sensor 100 by the embedded system, and the sensor 100 may obtain the control server 300 receives the signal. If information is not received, signals can be additionally transmitted by a preset number of times, and if information is not received that additionally transmitted signals are received, the control server 300 switches to a transmission method using a mesh network. signal can be transmitted.

On the other hand, a plurality of sensors may be installed in one disaster area, and when the sensor values installed in the disaster area are received differently, the control server 300 prioritizes a user close to a sensor with a high sensor value for safety. The location of the user may be transmitted to the terminal of the safety manager by matching with the manager.

5 is a flowchart illustrating a process of arranging a safety manager when there are several disaster occurrence areas in the same area according to an embodiment.

Referring to FIG. 5 , first, in step S501 , the control server 300 may check information on the area where the sensor transmitting the signal is located and select the confirmed area as a disaster area.

Specifically, the control server 300 may check the information of the area where the sensor transmitting the signal is located through the received signal and select the confirmed area as a disaster area. At this time, the control server 300 Considering the possibility of sensor error, the number of sensors that have transmitted signals among the sensors included in the area may be checked, and an area that has transmitted more than a standard number may be selected as a disaster area. That is, a plurality of sensors may be included in one region.

For example, the control server 300 receives a first signal transmitted from a first sensor included in a first region from the plurality of gateways 200, a second signal transmitted from a second sensor included in the first region, and a second signal transmitted from a second sensor included in the first region. A third signal transmitted from a third sensor included in the first region, a fourth signal transmitted from a fourth sensor included in the first region, a fifth signal transmitted from a fifth sensor included in the first region, and a first region A sixth signal transmitted from a sixth sensor included in , a seventh signal transmitted from a seventh sensor included in the first region, an eighth signal transmitted from an eighth sensor included in the second region, included in the second region When the ninth signal transmitted from the ninth sensor and the tenth signal transmitted from the tenth sensor included in the third region are received, and the reference number is three, the control server 300 controls the sensor included in the first region. By confirming that seven of the sensors sent signals, by confirming that two of the sensors included in the second region sent signals, and by confirming that one of the sensors included in the third region sent a signal, A first area to which signals are sent by more than three sensors, which is the reference number, may be selected as a disaster occurrence area.

In step S502, the control server 300 may check whether or not there are at least two areas selected as disaster occurrence areas in the same area. Here, the area may include at least one area. For example, a district may be a city unit and a region may be a district unit. A district may be a ward unit, and a region may be a dong unit. In addition, the database provided in the control server 300 may match and store a region and a region included in the corresponding region.

That is, the control server 300 may check whether at least two areas selected as disaster occurrence areas exist in the same area through the database.

When it is determined in step S502 that there are at least two regions selected as disaster occurrence regions within the same region, in step S503, the control server 300 may check the severity of disaster occurrence in each disaster occurrence region.

Specifically, the control server 300, when it is confirmed that at least two regions selected as disaster occurrence regions exist in the same region, prioritizes them through the severity of disaster occurrence in each disaster occurrence region, and prioritizes the selected priorities. In order to match the safety manager, the severity of disaster damage in the disaster area can be checked. At this time, the disaster area and the severity of disaster damage may be matched and stored in the database provided in the control server 300, and a process of selecting the disaster damage severity of the disaster area will be referred to FIG. 6 .

In step S504, the control server 300 may check whether the severity of disaster damage is greater than a threshold value. Here, the threshold value is a preset value and may vary according to embodiments.

When it is confirmed that the severity of damage caused by disaster is greater than the threshold value in step S504, in step S505, the control server 300 selects the disaster area as a priority area for damage recovery, checks the area to which the priority area for damage recovery belongs, and matches it to the area. The designated safety manager may be preferentially placed in the damage recovery priority area, and a damage recovery request message in the damage recovery priority area may be transmitted to the terminal of the safety manager. Here, the damage recovery request message may include a message requesting damage recovery in a disaster area, or may include a message requesting that a user located in a disaster area evacuate to a safe area.

Specifically, the control server 300 determines whether the disaster damage severity in the disaster area is greater than a preset threshold value, and when it is determined that the disaster damage severity in the disaster area is greater than the threshold value, the disaster area Selecting a damage recovery priority area, checking the area to which the damage recovery priority area belongs, placing a safety manager matched to the area with priority in the damage recovery priority area, and requesting damage recovery in the damage recovery priority area through the safety manager's terminal A damage recovery request message can be sent. Here, in the database provided in the control server 300, information of a zone and a safety manager who manages the safety of the zone may be matched and stored, and the safety manager includes the fire station, emergency rescue team, police, hospital, etc. It can be a person or facility that manages the safety of other areas. In addition, the control server 300 may communicate with the terminal of the safety manager by wire or wireless. Meanwhile, the control server 300 may differently arrange the number of safety managers disposed in a disaster area according to embodiments.

For example, area A and area B included in area A are identified as disaster occurrence areas, the severity of disaster damage in area A is 7, the severity of disaster damage in area B is 3, the threshold value is 5, If the safety managers matched to zone A are the first safety manager and the second safety manager, the control server 300 determines the disaster damage severity of zone A and zone B included in zone A as 7 and 3, respectively; Area A, where the severity of disaster damage is greater than the critical value of 5, is selected as a priority area for damage recovery, and the first safety manager matched to area A, which is a priority area for damage recovery, is assigned to Area A, A damage restoration request message may be transmitted to the terminal of the first safety manager to request damage restoration in the area.

If it is determined in step S504 that the severity of damage caused by the disaster is not greater than the threshold value, in step S506, the control server 300 checks the zone to which the disaster occurred area belongs and controls the safety manager preferentially placed in the damage recovery priority area. A manager may be arranged, and a damage recovery request message may be transmitted to the terminal of the safety manager in a damage recovery priority area.

Specifically, the control server 300 determines whether the disaster damage severity in the disaster area is greater than a preset threshold value, and if it is determined that the disaster damage severity in the disaster area is not greater than the threshold value, the disaster area The area to which the zone belongs is checked, and a safety manager excluding the safety manager preferentially disposed in the damage recovery priority area is disposed, and a damage recovery request message requesting damage recovery in the disaster area may be transmitted to the terminal of the safety manager. Here, in the database provided in the control server 300, information of a zone and a safety manager who manages the safety of the zone may be matched and stored, and the safety manager includes a fire station, emergency rescue team, police, hospital, etc. It can be a person or facility that manages the safety of other areas. In addition, the control server 300 may communicate with the terminal of the safety manager by wire or wireless. Meanwhile, the control server 300 may differently arrange the number of safety managers disposed in a disaster area according to embodiments.

For example, area A and area B included in area A are identified as disaster occurrence areas, the severity of disaster damage in area A is 7, the severity of disaster damage in area B is 3, the threshold value is 5, When the safety managers matched to area A are the first safety manager and the second safety manager, and the first safety manager is preferentially placed in area A, the control server 300 is included in area A and area B After confirming the severity of disaster damage as 7 and 3, respectively, and confirming that the severity of disaster damage in area B is smaller than the threshold value, the first safety manager assigned to area A with priority among the safety managers matched to area B or area Except for the safety manager, a second safety manager may be disposed in area Na, and a damage recovery request message requesting damage recovery in area Na may be transmitted to a terminal of the second safety manager.

If it is confirmed in step S502 that there is only one area selected as a disaster area in the same area, in step S507, the control server 300 checks the area to which the disaster area belongs, and transmits the terminal of the safety manager matched to the area. A damage recovery request message can be transmitted in a disaster area.

Specifically, when it is confirmed that there is only one area selected as a disaster area in the same area, the control server 300 checks the area to which the disaster area belongs in order to place a safety manager in that area without considering the priority. Accordingly, a damage recovery request message requesting damage recovery in a disaster area may be transmitted to a terminal of a safety manager matched to an area. In addition, the control server 300 may communicate with the terminal of the safety manager by wire or wireless.

For example, if only area A among areas included in area A is identified as a disaster area, and the safety manager matched to area A is a third safety manager, the control server 300 selects area A as a disaster area. It is confirmed that only area A exists, and a damage restoration request message requesting damage recovery of area A may be transmitted to the terminal of the third safety manager matched to area A, which is the area to which area A belongs.

For this reason, the control server 300, when a disaster occurs in several areas in the same area at the same time, preferentially places a safety manager in an area with a high severity of disaster damage, that is, a damage recovery priority area, so that the severity of disaster damage is high. Damage to the area can be minimized, and safety managers can be appropriately placed by arranging safety managers in the disaster area remaining after excluding the safety manager deployed in the damage recovery priority area.

6 is a flowchart for explaining a process of generating a disaster damage severity according to an embodiment.

Referring to FIG. 6, first, in step S601, the control server 300 determines the number of times disasters occur in a disaster area from a server of a public institution including at least one of a fire department, the Ministry of Public Administration and Security, a district office, and a city hall, and damage caused by a disaster. size can be obtained.

Specifically, the control server 300 may communicate with a server of a public institution including at least one of a fire department, the Ministry of Public Administration and Security, a district office, and a city hall through wired or wireless communication, and the number of times disasters have occurred and disasters in a disaster area from a server of a public institution It is possible to obtain the scale of damage caused by

In step S602 , the control server 300 may predict the severity of disaster damage based on the number of times disasters occur in the disaster area and the scale of damage caused by disasters. Here, the severity of disaster damage may be classified from 1 to 10, and may be classified in other ways. In addition, the severity of damage from a disaster is the degree to predict the scale and severity of damage when a disaster occurs. The smaller the damage severity of a disaster, the smaller the scale and severity of damage can be predicted when a disaster occurs in the area.

That is, the control server 300 may generate the severity of damage caused by a disaster through the number of times a disaster occurs in a disaster area and the scale of damage caused by a disaster acquired from a server of a public institution. Specifically, the control server 300 selects a disaster in which the damage caused by the disaster is greater than the threshold as a first disaster, and selects a disaster in which the damage caused by the disaster is not greater than the threshold as a second disaster, and the control server 300 determines that the first disaster is Both the number of occurrences and the number of second disasters generate the greatest disaster damage severity in a region that is greater than the limit number of times, and the control server 300 determines that the number of occurrences of the first disaster is greater than the number of thresholds, but the number of occurrences of the second disaster generates the next largest disaster damage severity in an area that is not more than the limit number, and the control server 300 has the first disaster occurrence number not greater than the limit number, but the second disaster number is greater than the limit number area The disaster damage severity of is generated next, and the control server 300 generates the smallest disaster damage severity in an area where both the number of occurrences of the first disaster and the number of occurrences of the second disaster are not more than the limit number. .

That is, the control server 300 may select the severity of disaster damage in the disaster area through the number of disasters and the scale of damage caused by the disaster, and preferentially place a safety manager according to the severity of disaster damage in the disaster area. can do.

On the other hand, the control server 300, in the process of generating the severity of disaster occurrence in the disaster area, not only the number of disasters and the scale of damage caused by disasters, but also the number of field data generated through sensors, the degree of aftereffects after disaster damage, The severity of disaster damage can be created by further considering the time of occurrence and the golden time.

7 is a flowchart illustrating a process of determining whether there is a risk of fire based on a thermal imaging camera according to an exemplary embodiment.

Specifically, the control server 300 may communicate with a thermal imaging camera installed in a region by wire or wirelessly, control the thermal imaging camera, and receive a thermal image from the thermal imaging camera. At this time, the thermal imaging camera is based on infrared rays. It may be a camera that displays the temperature of the space to be photographed in a predetermined color (red/yellow for a high-temperature region, purple for a low-temperature region, and blue-green for a central region). In this case, the infrared measurement/photography range may be 780 nm to 14 μm.

Next, detailed steps of determining whether there is a risk of fire based on the thermal image will be described.

Referring to FIG. 7 , first, in step S701, the control server 300 may extract a first image from a first viewpoint of a first thermal image.

Specifically, the control server 300 may control a first thermal image of the region to be captured through a thermal imaging camera installed in the region, receive the first thermal image in real time, and measure the first thermal image according to time. A first image, which is an image at any one time point (first time point) of an image image (video), may be captured and extracted as a still image image.

In step S702, the control server 300 may extract a second image at a second point in time after a predetermined time has elapsed from the first point in time of the first thermal image.

Specifically, the control server 300 may extract the second image in the same manner as extracting the first image at a second point in time that is later than the first point in time.

In this case, between the first and second viewpoints, the shooting range of the first thermal imaging camera may be fixed so as not to be adjusted. is marked as

In step S703, the control server 300 may generate a color spectrum from the second image from the lowest temperature to the highest temperature appearing in the second image.

Specifically, the control server 300 may generate a color spectrum bar in which the color changes continuously from purple, which is the color of the lowest temperature, to red, which is the color of the highest temperature, based on the temperature color appearing in the second image.

The color spectrum generated as described above is shown in FIG. 8 (a).

In step S704, the control server 300 may classify colors from the lowest temperature to the highest temperature appearing in the second image into at least five grades based on the color spectrum.

Specifically, the control server 300 may convert color spectrum bars of 'continuous' color changes into as many colors as the number of the classes.

FIG. 8(b) shows spectrum bars in the form of dividing the FIG. 8(a) into five levels.

In step S705, the control server 300 may convert the first color C1 appearing in the first image and the second image into a second color C2 according to each grade based on the grade.

Specifically, the control server 300 may convert various colors such as red-week-yellow-second-blue-southern-vio shown in the first image and the second image into colors for each grade. Therefore, only a total of 5 colors (as many as the number of the ratings) may be displayed in the converted final first image and second image.

In step S706, the control server 300 may count the number of first pixels in which the second colors C2 appear in the first image for each second color C2.

In step S707, the control server 300 may count the number of second pixels in which the second colors C2 appear in the second image for each second color C2.

In step S708, the control server 300 may count the number of third pixels that is the total number of pixels of the first image.

Specifically, the control server 300 may count the number of pixels constituting the first image and the second image.

For example, if the sizes of the first image and the second image are '1080*760', the control server 300 may count '1080*760 = 820,800' as the third pixel number.

Here, the first pixel number and the second pixel number may be counted as shown in Table 1 below.

Secondary Color (Rating) One 2 3 4 5 Total (number of third pixels) first number of pixels 205167 246130 246129 81932 41442 820800 Second number of pixels 123481 123013 205121 205025 164160 820800

In Table 1, a higher grade (from 1 to 5) may mean a color (red) representing a higher temperature. For example, in the example of FIG. 8 (b) , purple may represent 1st grade, cyan green 2nd grade, green 3rd grade, yellow 4th grade, and red 5th grade. In step S709, the control server 300 ) may calculate [number of first pixels / number of third pixels = first ratio] and [number of second pixels / number of third pixels = second ratio] for each second color.

That is, the control server 300 may calculate the percentage of each second color in each of the first image and the second image.

An example of calculating the first ratio and the second ratio according to the example of Table 1 is shown in Table 2.

Grade (Second Color) One 2 3 4 5 total first rate 0.24996 0.299866 0.299865 0.09982 0.05049 One second rate 0.15044 0.14987 0.249904 0.249787 0.2 One

As shown in Table 2, the sum of the first ratios and the sum of the second ratios each become 1. In step S710, the control server 300 selects a second color C2 that differs by at least four grades. At least one check group that is a combination of colors C2 may be extracted.

That is, the control server 300 may extract a combination of second colors C2 whose grades differ by more than four grades.

In the example of Table 2, since the grades are 5 steps from 1 to 5, only one pair of grades 1 and 5 can be extracted from the inspection group.

As another example, if the ranks are 6 steps from 1 to 6, three combinations of 6C2 that extract two out of the six ranks differ by four or more ranks [(1, 5), (1, 6) , (2, 6)] can be extracted as a check group.

In step S711, the control server 300 performs [(first ratio - second ratio) / first ratio of [third color that is a second color (C2) of a relatively low grade in the inspection group] for each inspection group. first increase/decrease rate] can be calculated.

That is, the control server 300 may calculate a first increase/decrease rate for each combination of inspection groups.

For example, if [(1, 5), (1, 6), (2, 6)] is the inspection group, the control server 300 selects the second color C2 with a relatively low grade in each of the three inspection groups. 1, 1, and 2 are designated as the third color, and a first change rate may be calculated for 1, 1, and 2.

The first change rate for grade 1 may be calculated as '(0.24996 - 0.15044) / 0.24996 = 0.3981' based on Table 2.

In step S712, the control server 300 performs [(second ratio - first ratio) / first ratio of [fourth color that is a second color (C2) of a relatively high rank among the inspection groups] for each inspection group. second increase/decrease rate] can be calculated.

Specifically, the control server 300 calculates the second change rate in the same way as the first change rate calculation process, but calculates the second change rate based on the second color C2 of a relatively high grade in each of the three inspection groups. can

For example, if [(1, 5), (1, 6), (2, 6)] is the inspection group, the control server 300 obtains a relatively high grade of the second color C2 in each of the three inspection groups. 5, 6, and 6 are designated as the fourth color, and a second increase/decrease rate may be calculated for 5, 6, and 6.

The second increase/decrease rate for grade 5 may be calculated as '(0.20000 - 0.05049) / 0.20000 = 2.961' based on Table 2.

In step S713 , the control server 300 may calculate [(second increase rate - first increase rate) * difference in grades between the second colors C2 = first increase index] for each inspection group.

That is, the control server 300 may calculate the first increase index by reflecting the grade difference between the second colors C2 based on the calculated first increase and decrease rates and the second increase and decrease rates.

Based on Table 2, the first change rate is 0.3981, the second change rate is 2.961, and the grade difference between the second colors C2 (the grade difference between the third color and the fourth color) is 4, so the control server 300 may calculate (2.961 - 0.3981) * 4 = 10.2516 as the first incremental exponent.

In addition, when there are several combinations of inspection groups, the control server 300 may calculate several first increase indices.

In step S714, the control server 300 returns the first increase factor to the second increase factor when there is one inspection group, and if there are two or more inspection groups, the average value of the first increase factor of the inspection groups is converted into a second increase factor. can be returned as

That is, the control server 300 may calculate a second increase factor as a final value based on the first increase factor(s).

For example, when the first incremental index is 10.2516, the control server 300 calculates (returns) 10.2516 as the second incremental index, and the control server 300 calculates (returns) the second incremental index as 10.2516 and 12.4518. In this case, the average value of 11.3517 can be calculated as the second increase index.

In addition, the control server 300 may determine that there is a risk of fire when the second increase index is greater than or equal to a predetermined value, and thus, the control server 300 may determine the risk of fire based on the first thermal image. can determine whether

For example, the control server 300 may designate a case in which the second increase index is 15 or more as a risk of fire, and determine that there is a risk of fire when the temperature change is rapid.
