Description

FIELD OF THE INVENTION [0001] The present invention relates to a fire-

The present invention relates to fire fighting equipment. More particularly, the present invention relates to a fire support apparatus capable of detecting the position of a person in a fire scene before a fire is suppressed.

Firefighting means to protect the life, body or property of a person by preventing or suppressing a fire and carrying out rescue or rescue activities in emergency situations such as fire, disaster or disaster. And life-saving means saving lives or bodies of people in emergency situations such as fire, disaster or disaster.

In general, the fire scene is dark due to the interruption of the electricity supply in the building, and it is filled with smoke generated by combustion. In addition, the fire scene is accompanied by a sound of a fire alarm in the building, an explosion sound of the object due to the heating expansion, and other sound of fire.

Therefore, it is difficult to visually distinguish the shapes of living and non - living bodies, and it is also difficult to perceive the sound of living things only audibly. Because of this, there is a limit to firefighters' discovery of fire and immediate rescue operations at fire sites.

However, if firefighters can preemptively acquire the location of ignition points and persons before they extinguish the fire, effective firefighting activities such as concentrated suppression of ignition points and life-saving structures bypassing the ignition points become possible.

Therefore, various solutions are required to detect the ignition point and the position of the human life before the fire is suppressed.

Hereinafter, the construction and operation of the fire fighting support apparatus 100 according to various embodiments of the present invention will be described in more detail.

3 is a logical block diagram of a fire fighting support apparatus according to an embodiment of the present invention.

3, the fire fighting assistance apparatus 100 according to an embodiment of the present invention includes a communication unit 105, an input / output unit 110, a fire control unit 115, and a structure control unit 120 . Since the components of the fire support apparatus 100 are merely functionally distinguished elements, one or more of the components may be integrated with each other in an actual physical environment.

The communication unit 105 can transmit and receive signals to and from the network hub 20, the fire center server 200, and the building management server 300, respectively. Specifically, the communication unit 105 can transmit and receive signals to / from the network hub 20. The communication unit 105 can transmit and receive signals to / from the electronic device 30 via the network hub 20. [ The communication unit 105 can transmit and receive signals to and from the fire department server 200. The communication unit 105 can transmit and receive signals to and from the building management server 300. [

Particularly, the communication unit 105 can transmit and receive signals to / from the network hub 20 or the electronic device 30 through ICMP (Internet Control Message Protocol). Specifically, the communication unit 105 determines whether a signal arrives at the network hub 20 or the electronic device 30 through the Ping (Packet Internet Grouper) of the ICMP protocol, or if the signal reaches the network hub 20 or the electronic device 30 It is possible to check whether a failure has occurred.

The input / output unit 110 can input and output a signal for an interface between the fire fighting support apparatus 100 and a user. Specifically, the input / output unit 110 can receive the location of the network hub 20 from the user. The input / output unit 110 may receive a period for detecting whether a fire has occurred from the user. The input / output unit 110 can receive a threshold distance and a critical grade as a reference for performing supply or exhaust in the building 1 from the user. The input / output unit 110 can output information on the occurrence of the fire, the ignition point, and the diffusion direction of the fire.

The fire control unit 115 can detect the occurrence of the fire 10 in the building 1, detect the ignition point 11 and detect the diffusion direction of the fire 10. The fire control unit 115 may include the building structure identification unit 116, the ignition reference generation unit 117, the ignition point detection unit 118, and the fire diffusion management unit 119.

Describing the components of the fire control unit 115, the building structure identification unit 116 can identify the structure of the building 1. [ The building structure identification unit 116 can identify the location of the network hub 20 existing in the building 1. [ The building structure identification unit 116 can identify the location of the electronic device 30 existing in the building 1. [

Specifically, the building structure identification unit 116 extracts a design drawing of the building 1 from a database. The building structure identification unit 116 determines the positions of three or more network hubs 20 in the extracted design drawing. The location of the network hub 20 may be input at the time of designing the building 1, received from the user, or received via the communication unit 105, but is not limited thereto. The building structure identification unit 116 maps the determined location of the network hub 20 to the design drawing.

The building structure identification unit 116 instructs the three or more network hubs 20 to transmit signals to the electronic device 30 through the communication unit 105. [ The electronic device 30 may be connected to or connected to the network hub 20. The building structure identification unit 116 instructs the three or more network hubs 20 to measure the quality of the response signal received from the electronic device 30 through the communication unit 105, respectively. The building structure identification unit 116 receives the quality of the response signal measured by each of the three or more network hubs 20 via the communication unit 105. The building structure identification unit 116 performs triangulation based on the strength of the signals included in the quality of the received signals of the three or more response signals to determine the position of the electronic device 30. [ The building structure identification unit 116 maps the determined position of the electronic device 30 to the design drawing.

Here, the quality of a signal may include, but is not limited to, a signal strength, a response speed, a data communication speed, or an error rate. Also, the strength of a signal can be measured by any one of Received Signal Strength Indication (RSSI), Reference Signals Received Power (RSRP), and Reference Signal Received Quality (RSRQ).

In particular, the building structure identification section 116 can correct the quality of the response signal attenuated by the wall of the building 1. Specifically, the building structure identification unit 116 performs triangulation based on the intensity of the response signal received from the electronic device 30, thereby determining a temporary position of the electronic device 30. [ The building structure identification section 116 identifies the wall located between the temporary location of the determined electronic device 30 and the network hub 20 based on the design drawing of the building 1. The building structure identification unit 116 extracts the property of the identified wall from the database. Here, the properties of the wall may include, but are not limited to, a material constituting the wall, a structure embedded in the wall, and thickness of the wall. The building structure identification unit 116 corrects the quality of the response signal received from the electronic device 30 by the network hub 20 based on the extracted property of the wall. For example, the building structure identification unit 116 may increase the strength of the response signal by 20% when the strength of the response signal is determined to be attenuated by 20% due to the property of the wall. Then, the building structure identification unit 116 can perform the triangulation again based on the intensity of the corrected response signal, thereby determining the true position of the electronic device 30. [

The ignition reference generation unit 117 may generate an ignition reference for determining whether a fire occurs before a fire occurs. Here, the ignition criterion is a quality standard of a typical signal that can be received from the network hub 20 or the electronic device 30 when an event such as a fire does not occur in the building 1. Specifically, the ignition reference generation section 117 transmits a signal to all the network hub 20 and the electronic device 30 identified by the building structure identification section 116, and receives a response signal. The ignition reference generation unit 117 measures the quality of the received response signal. The ignition reference generation unit 117 generates the ignition reference for each of the network hub 20 and the electronic device 30 based on the measured quality of the response signal.

At this time, the ignition reference generation unit 117 can transmit the Ping signal of the ICMP protocol and receive the response signal of the Ping. Therefore, all of the network hub 20 or the electronic device 30, which is supplied with power, can respond to the signal transmission of the ignition reference generation section 117 by the property of the ICMP protocol. The network hub 20 or the electronic device 30 can respond to the signal transmission of the ignition reference generation section 117 with the same performance regardless of the amount of the communication load loaded on the network hub 20 or the electronic device 30 can do.

The ignition point detection unit 118 can detect the occurrence of a fire in the building 1 and the ignition point. Specifically, the ignition point detecting section 118 performs communication with all of the network hub 20 and the electronic device 30 identified by the building structure identifying section 116 according to a predetermined period. At this time, the ignition point detecting section 118 can transmit the Ping signal of the ICMP protocol and receive the response signal of the Ping every predetermined period.

Here, the period is a time interval for detecting whether a fire occurs or not. The shorter the period, the higher the sensitivity to detect the occurrence of a fire, but the communication load of the network hub 20 and the electronic device 30 may increase. The longer the period, the lower the sensitivity to detect the occurrence of a fire, but the communication load of the network hub 20 and the electronic device 30 can be reduced. The cycle may be input at the time of installation of the fire fighting support apparatus 100, input from the user, or received through the communication unit 105, but is not limited thereto.

The firing point detection unit 118 determines whether a signal has been received from all the network hub 20 and the electronic device 30 identified by the building structure identification unit 116. [ The firing point detector 118 determines that a fire has occurred when there is a network hub 20 or an electronic device 30 that does not receive a response signal. The ignition point detecting unit 118 can determine the position of the network hub 20 or the electronic device 30 to which the response signal is not received as the ignition point.

The ignition point detection unit 118 detects the quality of the received signal and the ignition reference generation unit 117 when a signal is received from all the network hub 20 and the electronic equipment 30 identified by the building structure identification unit 116. [ It is determined that a fire has occurred when the quality of a signal received from two or more network hubs 20 or electronic devices 30 is different from the ignition reference. This is because, if the quality of a signal received from one of the network hub 20 or the electronic device 30 is different from the ignition reference, it may be a failure of the corresponding network hub 20 or the electronic device 30. [ The ignition point detecting unit 118 can determine the position of the network hub 20 or the electronic device 30 that has transmitted the signal with the highest quality difference as the ignition point, in comparison with the ignition reference.

More specifically, if the temperature in the building 1 suddenly rises due to fire, the quality of the received signal can also be drastically changed. For example, if the temperature suddenly rises, a failure may occur in the network hub 20 or the electronic device 30, so that the signal may not be normally transmitted. Alternatively, the network hub 20 or the electronic device 30 normally transmits a signal, but an error may occur in the signal being transmitted due to a rapidly changing temperature.

There is a high possibility that the fire fighting support apparatus 100 can not receive any signal from the network hub 20 or the electronic device 30 when the temperature suddenly changes to such an extent that the failure occurs in the network hub 20 or the electronic device 30. [ Accordingly, when the network hub 20 or the electronic device 30 normally transmits a signal but an error occurs in the signal being transmitted due to the suddenly changing temperature, the fire support apparatus 100 according to the embodiment of the present invention .

Accordingly, the ignition point detecting unit 118 detects the ignition point of the signal received from the network hub 20 or the electronic device 30 by comparing the phase of the reference signal with the phase of the reference signal, The location of the network hub 20 or the electronic device 30 that has transmitted the signal having the delayed phase may be determined as a firing point. This is because the signal transmitted from the first device can be delayed in phase due to a change in temperature and can be received by the second device. Here, the reference signal is a signal for judging whether or not a signal transmitted from the first apparatus is received by the second apparatus in a seamless manner. The reference signal may be included in a part of a data packet to be transmitted and may be transmitted in advance before a data packet to be transmitted is transmitted.

Alternatively, the ignition point detector 118 may detect that the error rate generated by the white gauss noise among the signals received from the network hub 20 or the electronic device 30 exceeds the total error rate included in the ignition criterion If there is a signal, the position of the network hub 20 or the electronic device 30 that has transmitted a signal exceeding the total error rate can be determined as a firing point. The signal transmitted from the first device is increased in white Gaussian noise due to the change in temperature and can be received by the second device. Here, white Gaussian noise is a noise according to a Gaussian distribution (normal distribution) included in all frequency bands of a signal, and is a noise sensitively increased by a temperature rise.

The fire spread management section 119 can detect the diffusion direction of the fire generated in the building 1. [ Specifically, after the ignition point is detected by the ignition point detection unit 118, the fire spread management unit 119 detects all the network hubs 20 identified by the building structure identification unit 116, And the electronic device (30). At this time, the fire spread management section 119 can transmit the Ping signal of the ICMP protocol and receive the response signal of the Ping every predetermined period.

The fire propagation management unit 119 compares the quality of a plurality of signals received from the network hub 20 or the electronic device 30 to determine the position of the network hub 20 or the electronic device 30 . The fire diffusion management unit 119 can determine the direction of diffusion of the fire relative to the position of the network hub 20 or the electronic device 30 whose signal quality is further lowered at the ignition point.

The structure control unit 120 can detect the presence of life in the building 1, detect the location 41 of the life, and evaluate the risk of the life. The structure control unit 120 may include a human presence detection unit 121, a human location detection unit 122, a risk assessment unit 123, and a firefighting facility control unit 124.

Describing the constituent elements of the structure control unit 120, the person presence detection unit 121 can detect whether or not the personal information in the building 1 exists. The presence detection unit 121 detects presence or absence of a person's life on the assumption that the user of the portable terminal 40 possesses or grasps the portable terminal 40. [

Specifically, the presence detection unit 121 determines whether there is a portable terminal 40 connected to three or more network hubs 20 existing in the building 1 through the communication unit 105. [ The presence detection unit 121 instructs the corresponding hub 20 to transmit the first signal to the portable terminal 40 when the portable terminal 40 connected to the specific network hub 20 exists. The presence detection unit 121 instructs the network hub 20 to measure the quality of the first response signal received from the portable terminal 40. [ The presence detection unit 121 receives the quality of the first response signal measured by the network hub 20. The presence detection unit 121 instructs the network hub 20 to transmit the second signal to the portable terminal 40. [ The presence detection unit 121 instructs the network hub 20 to measure the quality of the second response signal received from the portable terminal 40. [ The human presence detection unit 121 receives the quality of the second response signal measured by the network hub 20. Based on the amount of change between the quality of the first response signal and the quality of the second response signal, the presence detection unit 121 determines whether the position of the portable terminal 40 has changed, That is, it is possible to determine whether a person lives in the building 1. At this time, the signal transmitted / received between the network hub 20 and the portable terminal 40 may be a ping signal of the ICMP protocol and a ping response signal.

In particular, the presence detection unit 121 can determine whether the quality of the response signal received from the portable terminal 40 has changed due to the positional change of the portable terminal 40 or has changed due to the temperature rise due to the fire. Generally, the closer the position of the transmitter that transmits the signal and the position of the receiver that receives the signal, the greater the strength of the signal and the lower the error rate of the signal. Conversely, the farther the position of the transmitter that transmits the signal and the position of the receiver that receives the signal become, the less the strength of the signal and the higher the error rate of the signal. Therefore, if the strength of the signal received from the portable terminal 40 increases but the error rate of the received signal also increases, the presence detector 121 may determine that the position of the portable terminal 40 has changed. That is, although the strength of a signal received from the portable terminal 40 is increased due to a distance between the network hub 20 and the portable terminal 40, the presence detector 121 may increase the strength of the signal received from the portable terminal 40 40 is increased.

The life position detecting unit 122 can detect the position of a person in the building 1 when the position of the portable terminal 40 is changed and it is determined that a person's name exists in the building 1. [ Specifically, the personal name position detection unit 122 instructs the three or more network hubs 20 to transmit signals to the portable terminal 40 through the communication unit 105. The personal name position detection unit 122 instructs three or more network hubs 20 to measure the quality of the response signal received from the portable terminal 40 through the communication unit 105, The personal position detecting unit 122 receives the quality of the response signal measured by each of the three or more network hubs 20 through the communication unit 150. The personal position detecting unit 122 performs triangulation based on the intensity of the signals included in the quality of the received three or more response signals to determine the position of the portable terminal 40. [ Then, the life position detection unit 122 maps the determined position of the portable terminal 40 to the design drawing.

Particularly, the life position detection unit 122 can correct the quality of the response signal attenuated by the wall of the building 1. Specifically, the life position detection unit 122 performs a first triangulation based on the strength of the response signal received from the portable terminal 40, thereby determining a temporary position of the portable terminal 40. [ Based on the design drawing of the building 1, the life position detection unit 122 identifies a wall positioned between the temporary position of the portable terminal 40 and the network hub 20. [ The personal name position detection unit 122 extracts the attribute of the identified wall from the database. Here, the properties of the wall may include, but are not limited to, a material constituting the wall, a structure embedded in the wall, and thickness of the wall. The life position detection unit 122 corrects the quality of the response signal received from the portable terminal 40 by the network hub 20 based on the extracted property of the wall. Then, the life structure detector 122 may perform a second triangulation based on the strength of the corrected response signal to determine the true position of the portable terminal 40.

The risk evaluation unit 123 can evaluate the risk of life in the building 1. Specifically, the risk evaluation unit 123 calculates a position of the portable terminal 40 based on the relative position between the position 11 of the ignition point determined through the ignition point detection unit 118 and the position of the portable terminal 40 determined through the life position detection unit 122, The risk of the portable terminal 40 to fire can be evaluated. Here, the risk refers to the probability that a person living in the building 1 is rescued without losing a fire. The risk can be represented by an integer class between a minimum value and a maximum value, but not limited thereto, and can be expressed in a predefined character class. For example, it is possible to express the degree of risk as an integer grade of 0 to 10, assuming that a person who lives in the building 1 must lose 0, and 10 if it is to be built.

More specifically, the risk evaluation unit 123 can evaluate the risk of the portable terminal 40 according to the position of the ignition point 11. For example, the risk evaluation unit 123 evaluates the risk as the distance between the ignition point 11 and the portable terminal 40 is higher, and the distance between the ignition point 11 and the portable terminal 40 is higher The risk can be evaluated in a low level.

The risk evaluation unit 123 can evaluate the risk of the portable terminal 40 according to the position or the attribute of the wall existing between the ignition point 11 and the portable terminal 40. [ For example, the risk assessment unit 123 may evaluate the risk as the number of walls existing between the ignition point 11 and the portable terminal 40 increases. The risk assessment unit 123 can evaluate the risk based on the wall material, the internal structure, and the thickness of the wall existing between the ignition point 11 and the portable terminal 40. [

The risk evaluation unit 123 can evaluate the risk of the portable terminal 40 according to the position of the exit of the building 1. [ For example, the risk assessment unit 123 evaluates the risk to be lower as the distance between the position of the exit of the emergency exit and the distance between the portable terminal 40 is lower and increases as the distance between the position of the exit of the emergency exit and the portable terminal 40 increases. Can be evaluated.

The risk evaluation unit 123 can evaluate the risk of the portable terminal 40 according to the location or property of the room or the room where the portable terminal 40 is located. For example, the risk assessment unit 123 evaluates the risk with a high degree when the room or the room where the portable terminal 40 is located is located in a higher layer in the building 1, Or if the yarn is present in a lower layer within the building 1, the risk can be evaluated to be lower. The risk assessment unit 123 evaluates the degree of risk as the number of windows in the room where the portable terminal 40 is located or the number of windows in the room is low, The lower the number, the higher the risk.

In particular, when the communication between the portable terminal 40 and the network hub 20, which is the subject of risk assessment, is disconnected, the risk evaluation unit 123 may change the evaluated risk to the highest rating. For example, if the risk is represented by an integer between 0 and 10, the risk assessment unit 123 may perform a preliminary evaluation for the portable terminal 40 when the communication with the portable terminal 40, The risk can be changed to 10.

The fire fighting facility control unit 124 can control the fire fighting facilities in the building 1 through the building management server 300 based on the risk evaluated by the risk evaluation unit 123. [ Specifically, the fire-fighting facility control unit 124 can instruct the building management server 300 to perform supply to the portable terminal 40 on the basis of the risk. The fire fighting facility control unit 124 may command the building management server 300 to perform the evacuation to the ignition point 11 based on the risk. When the relative distance between the ignition point 11 and the portable terminal 40 is greater than the critical distance and the risk level is equal to or higher than the critical level, the fire fighting facility control unit 124 performs the supply of air to the position of the portable terminal 40, It is possible to instruct the building management server 300 to perform the exhaust to the point.

Here, the critical distance is a distance at which the air supplied to the position of the portable terminal 40 is not supplied to the ignition point 11. In addition, the critical grade is a rating that represents a degree of risk that the user of the portable terminal 40 will suffer permanent damage to the body unless promptly supplying the position of the portable terminal 40. When the air supply is performed in order to increase the residence rate of human life, the fire can be further diffused, and when the exhaust is performed to prevent the spread of the fire, the structure rate of the life can be lowered, And to perform the supply and exhaust within the limits of distance and critical grade.

However, even if the relative distance between the ignition point 11 and the portable terminal 40 is longer than the critical distance and the risk is higher than the critical grade, the ignition point 11 and the portable terminal 40 are placed in the same room, The air supplied to the position of the portable terminal 40 can be supplied to the ignition point 11. [ Therefore, the fire fighting facility control unit 124 can instruct the building management server 300 to perform the supply or exhaust only when there is a variant between the ignition point 11 and the portable terminal 40. [

The fire fighting facility control unit 124 blocks the fire wall existing between the ignition point 11 and the portable terminal 40 and controls the building management server 300 so that the fire wall existing between the portable terminal 40 and the exit is not blocked. . ≪ / RTI > In addition, the fire-fighting facility control unit 124 controls the fire-fighting facility control unit 124 so that, even if the distance between the ignition point 11 and the portable terminal 40 is long, The server 300 may be instructed.

The fire information propagation unit 125 may transmit information related to the fire to the fire department server 200. [ Specifically, the fire information propagation unit 125 transmits a fire occurrence detected by the fire detection point detector 118, an ignition point, and a fire diffusion direction determined by the fire diffusion management unit 119 to the fire department server 200 . The fire information propagation unit 125 can transmit information related to fire through the network hub 20 to the fire department server 200. However, when communication with the fire department 200 can not be performed through the network hub 20, the fire information propagation unit 125 may use the line directly connected to the fire department server 200 to transmit information related to the fire .
