Description

Intelligent Fire Evacuation Leader {Smart Fire Evacuation Leader}

The present invention relates to an intelligent fire evacuation guidance system, and more particularly, to an intelligent fire evacuation guidance system that can quickly and safely evacuate the evacuator by actively securing an optimal evacuation route in the event of a fire.

In general, in the form of a fire, the smoke generation rate is slow during the initial fire, while the gas generated due to incomplete combustion is generated in a small amount, so the fire monitoring is performed through heat and gas as a medium.

Currently used fire sensor is composed of ion-chemical or photoelectric smoke detection sensor mounted to the ceiling in the building, the smoke detection sensor recognizes the fire when a large amount of smoke due to incomplete combustion occurs.

In other words, the general smoke sensor responds to a high concentration of smoke of 20-30%, and warns of a fire based on this. Therefore, in recent years, when a smoke occurs due to a fire in a building in which a fire door is installed, smoke or gas does not spread to the surroundings, and a fire sensor spaced apart from an ignition area does not exhibit its function.

In order to solve this problem, in recent years, the fire signal detected by the fire sensor is mounted on the network to provide a warning message for evacuation, a fire suppression warning message, a fire prevention warning message, etc. In addition, it is equipped with a number of CCTVs as an additional facility to monitor the ignition zone and the ignition zone in real time.

However, even if a system or network for fire protection is implemented, the best way to prevent fires in advance is to find a fire detection sensor that can recognize and notify the initial ignition zone quickly. It should be detected based on responsiveness and reliability.

Nevertheless, the current fire sensor recognizes whether or not a fire occurs due to the smoke detection, it is recognized that a large amount of smoke after the fire. Therefore, a general fire sensor has been criticized for its extremely low responsiveness, and a fire protection system designed based on such a fire sensor causes a problem that a fire cannot be prevented in advance.

In order to solve the above problems, Patent Document 1 is a detection sensor consisting of a plurality of types of sensors for complex fire detection; A signal amplifier for amplifying each detected signal recognized by the detection sensor to a predetermined level; A signal converter for converting each output signal of the signal amplifier into a digital signal; A program memory in which a measurement value calculating program for converting the measurement value information detected from the detection sensor and the measurement value information into standard value information is mounted; A system control unit for receiving measurement value information of the digital signal provided by the signal conversion unit and calculating a standard value of measurement value information currently detected based on a reception result and the detection value calculation program; A display unit connected to an output port of the system control unit to display the standard value information; It is connected to the input port of the system control unit to provide a fire-signal composite detection device consisting of an address setting switch for setting a unique address of the system to measure the gas, humidity, temperature complex and maximize the accuracy of the gas sensor, In case of overload, short circuit, contact overheat, product defect fire, static electricity due to high temperature and low humidity, which may occur in communication and electrical cabinet (rack), narrow space, fire, etc. Fire prevention can be performed more accurately by detecting fire factors in advance.

On the other hand, the most important thing to do when preventing fire is to minimize the damage to life.

In this regard, Patent Document 1 has a problem of not only securing the safety and evacuation route of the evacuator but also expecting the purpose and effect in preventing fire.

Patent Literature 2, on the other hand, detects a fire in stages and transmits an image to generate a control signal. Human safety can be minimized by securing an evacuation route.

However, in case of fire, the biggest culprit of human life damage is not direct flame, but patent document 2 secures escape route to avoid flame in that poisonous gas and carbon monoxide caused by incomplete combustion greatly increase the fatality in fire. An unfortunate situation could arise where evacuators would pass through a place where carbon monoxide is saturated.

That is, Patent Document 2 concentrates only on the occurrence of smoke, gas, flame, and the like, and based on such fragmentary information, it does not adequately reflect a rapidly changing fire situation on the site.

In other words, as social structures become more urbanized, higher, and denser, the types of fires become more complex, resulting in a steadily increasing number of casualties and property damages.In 2016, 43,413 fires occurred. 2,024 people.

In the case of fires in fireproof buildings, even if there is no direct flame, many people can be damaged in a short time, such as poisoning by toxic gas or asphyxiation by carbon monoxide. There is an urgent need for a system that can respond intelligently to ensure maximum security.

In order to solve the above problems, the present invention is an intelligent fire that can quickly and safely evacuate evacuators by actively securing an optimal evacuation route through a logical analysis of an algorithm combining a real-time carbon monoxide concentration and various evacuation logics when a fire occurs.

In order to achieve the above object, the present invention is a sensor unit having a carbon monoxide concentration sensor for detecting the concentration of carbon monoxide and disposed at appropriate intervals along the evacuation path and a temperature sensor for sensing the temperature; A server configured to logically analyze real-time information of the sensor unit and a preset algorithm to set a real-time evacuation route; A communication unit which transmits the information of the sensor unit to a server and transmits the evacuation route set in the server to the sensor unit; It is intermittently arranged in the evacuation path provides an intelligent fire evacuation guidance system comprising a central monitor for displaying the evacuation route set by the server to the naked eye.

Here, the sensor unit may further include a direction indicating that a prohibition mark or an arrow is displayed so as to check whether the evacuation route is safely entered and the evacuation direction under the control of the server, or whether the evacuation route is safely entered under the control of the server. It characterized in that it further comprises a wall pad displaying a prohibition mark or an arrow so that the evacuation direction can be confirmed.

On the other hand, the communication unit and a data logger for storing the real-time information of the sensor unit; It characterized in that it comprises a wireless or wired communication device to enable the mutual transmission and reception of the real-time information of the data logger and the evacuation path of the server.

By providing the present invention configured as described above, there is an effect that can ensure an optimal evacuation route to evacuate the evacuator quickly and safely in the event of a fire.

Figure 2 is an exemplary diagram to secure the evacuation route through the intelligent fire evacuation guidance system according to the present invention.
3 is a flow chart showing the logic structure of the intelligent fire evacuation guidance system according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

The intelligent fire evacuation guidance system of the present invention is largely a display such as a sensor unit 100, a communication unit 300 having a data logger 310, a server 200 having SFEL software, and a monitor or wall pad 140. It consists of a device.

That is, as shown in Figures 1 to 3, the sensor unit 100 is attached to the ceiling or the wall to continuously measure the change in carbon monoxide concentration and temperature.

The sensor unit 100 is disposed at appropriate intervals along the evacuation path 500 and has a carbon monoxide concentration sensor 110 for detecting the concentration of carbon monoxide and a temperature sensor 120 for sensing the temperature.

The measured information is transmitted to the server through the data logger and the optimal evacuation route can be analyzed through the SFEL software.

Here, the server 200 may set a real-time evacuation path by logically analyzing the real-time information of the sensor unit 100 and a predetermined algorithm.

In this case, the communication unit 300 may transmit the information of the sensor unit 100 to the server 200, and transmit the evacuation path set in the server 200 to the sensor unit 100.

The derived evacuation route is guided to the direction indicator of the sensor unit, the wall pad 140 installed on the wall, and the central monitor 400 installed on the main evacuation passage. In order to secure the clock in case of fire, the direction indicator, the wall pad 140, and the central monitor 400 are preferably different in installation height.

In other words, the evacuation route 500 may have a central monitor 400 intermittently arranged to display the evacuation route set by the server 200 so that the evacuator can visually check the evacuation route.

In addition, the sensor unit 100 may have a direction indicator 130 in which a prohibition mark or an arrow is displayed so as to check whether the evacuation path is entered and the evacuation direction under the control of the server 200.

In addition, the sensor unit 100 may further include a wall pad 140 displaying a prohibition mark or an arrow so as to check whether the evacuation route is entered and the evacuation direction under the control of the server 200.

Therefore, it is most effective to use the direction indicators 130, the wall pads 140, and the central monitor 400 appropriately arranged at each position of the evacuation path 500.

In addition, the wall pad 140 has a built-in emergency call or emergency button that can be in direct contact with the central control room of the building, even if the evacuation is not secured by the proposed present technology, if the evacuator is isolated from the outside It is desirable to have an emergency contact function to carry out rescue activities.

On the other hand, the communication unit 300 includes a data logger 310 for storing real-time information of the sensor unit 100; It may include a communication unit 320 made of a wireless or wired so as to be able to transmit and receive the real-time information of the data logger 310 and the set evacuation path of the server 200 to each other.

The server 200 includes an information receiver 210 for receiving information transmitted through the communication unit 300; An information storage unit 220 storing information collection and algorithms received through the information receiving unit 210; The information analysis unit 220 may be configured as an information analysis unit 230 to logically analyze the algorithm and information to set a safe evacuation path.

In other words, the information analyzer 230 may have the following logical structure with SFEL software embedded in the server 200.

That is, the present invention uses an algorithm considering the change of carbon monoxide concentration and various situations in evacuation route analysis.

For example, as shown in Figure 3, considering the concentration of carbon monoxide, the viable time according to the concentration, the moving speed by walking in case of fire, the design of the building, the location of each safety device, the fire occurred in close proximity to the emergency exit Even if safety is ensured, you may be able to direct them to the final evacuation route.

First, the priority is analyzed by the carbon monoxide concentration for each region of the evacuation route by the information provided through the carbon monoxide concentration sensor 110 of the sensor unit 100 at each position.

Next, the priority of the temperature change to the next priority is analyzed by the information provided through the temperature sensor 120 of the sensor unit 100.

Therefore, when carbon monoxide has the same concentration at each position, the place where the temperature is relatively low is set as the priority of the evacuation route.

Then, the shortest evacuation route is established by applying it to the building plan.

According to the concentration of carbon monoxide, the optimal evacuation route should be established considering the survival time of the evacuator.

In consideration of the number of evacuees and the speed at which they are walking, set up and provide alternative emergency exits such as barriers and windows in case of danger.

The evacuation route should be guided to the location of safety equipment such as steel bars considering the vertical moving height between floors.

As described above, the algorithm applied to the SFEL software can be applied in consideration of various factors such as the structure of a building, the number of people accommodated, the devices in operation, and the law of fire response.

In other words, since carbon monoxide starts to be generated by incomplete combustion at the beginning of a fire, it is an important measure of fire recognition and first responding. This is the first item to consider when developing the system.

In addition, simply detecting the gas, smoke, temperature, flame, etc. in the ever-changing fire scene cannot adequately respond to the changing fire situation. Therefore, in order to analyze the real-time evacuation route and maximize the survival probability, It is very important to use time series data such as carbon monoxide concentration and temperature which can represent the change of fire condition over time as input data.

In addition, unlike existing products which recently use a display device such as a wall pad and wireless communication, wired communication and wireless communication may be used in combination.

No matter how advanced wireless communication technology is, the possibility of data transmission delay that can occur when using wireless communication cannot be ignored. In the case of using a fire sensor, wireless communication is available because it does not mean a slight data transmission delay itself.

In other words, the reliability of the evacuated route is analyzed logically when the evacuation route is analyzed according to the structure of the entire building by grasping the change in real-time carbon monoxide concentration. Since fatal injury can occur, it is desirable to enable both wired and wireless communication to minimize damage.

By providing such a configuration, social and technical side effects can be obtained.

First, in terms of social aspects, fireproof buildings have high airtightness, resulting in many casualties such as poisoning by toxic gas or asphyxiation due to lack of oxygen.

Second, in the technical aspect, the main competition technology is the sensor fire monitoring technology, and the blank technology is the fire response technology, and carbon monoxide is a good indicator for the fire detection because carbon monoxide is generated from the beginning of fire by incomplete combustion.

Therefore, considering the fact that carbon monoxide poisoning and asphyxiation of human life due to asphyxiation rather than damage due to fire, the survival rate can be improved by proposing a avoidance route corresponding to the change of carbon monoxide concentration.
