Description

System for detecting fire using smart fire detector based on IoT and the smart fire detector

The present invention relates to a fire detector and a fire detection system using the same, and in particular, by providing a fire safety management service platform incorporating indoor location-based technologies, fire detection and personnel in a building are simultaneously monitored to provide emergency evacuation within golden time. It relates to a smart fire detector based on the Internet of Things capable of extinguishing a fire at the first ignition point and a fire detection system using the same.

Fire is a great disaster that takes everything away in an instant. In addition to the economic loss that goes away with fire in the event of a fire, recovery is costly and time consuming.

In particular, fires not only result in economic losses, but also human lives that cannot be changed for anything and cannot be restored forever.

If you look at the recent fire events (Jecheon, Miryang, etc.) that occur continuously, even a place with good fire protection facilities can lead to a big fire in a moment if you are a little vigilant. This is because there is no control tower in the center of the accident where the initial small fire spreads into a large fire to control the fire in the building.

Therefore, it is most important to try to prevent fire, but in the event of a fire, it is important to identify the ignition point and the cause of the fire within the shortest time to quickly extinguish the fire and minimize human damage.

Looking at the existing prior art documents, Korean Patent Registration No. 10-0971623 (Prior Art 1) relates to an automatic disaster warning and evacuation guidance device for high-rise buildings, and automatically alerts when an emergency situation such as a disaster or disaster occurs. An apparatus for issuing and inducing evacuation is disclosed. Prior art 1 receives the signal from the sensor unit that detects disasters, disasters, etc. in each building section and delivers it to the central server through the repeater. The alarm is notified by voice, and each evacuation guidance lamp is configured to indicate the evacuation direction and to deliver text messages through a mobile phone.

However, since the prior art 1 only transmits a fire text message to the user's mobile phone, it does not help anyone who is not familiar with the interior of the building in an emergency situation in which a fire occurs, and even a person who resides in the building can use his There is a problem in that it is difficult to evacuate to a safe emergency exit or evacuation site using only text because it cannot accurately judge the lakes of other offices.

On the other hand, Korean Patent Application Publication No. 10-2019-0040887 (Advanced Technology 2) relates to the Internet of Things (IoT) smart fire detection guidance system using the existing fire detection sensor, and utilizes the existing fire detection sensor. When a fire is notified, a drawing or web image containing the location, emergency exit location, entry location (evacuation direction), etc. registered in the fire detector as a registered contact information is sent to the SMS text or the push function of the application so that evacuation and rescue is possible in a short time. An IoT smart fire detection guidance system has been disclosed.

However, the above prior art 2 also only provides information necessary for evacuation to personnel in the fire-prone area, and there is a problem in that it is not helpful at all in terms of actively suppressing fire and saving lives.

Therefore, it is desperately necessary to have a control system capable of urgently evacuating personnel in the building and performing rapid rescue of humans who have not been evacuated by grasping the exact fire situation in the building.

Referring first to FIG. 11, the operation server 310 of the fire detection system using the Internet of Things-based smart fire detection according to the present invention receives the data packet of FIG. 10c from the fire detector 200 and stores it in the database 320. (501), when a fire is confirmed by checking the fire alarm field in the received packet (503), the coordinate value (x,y) where the fire is detected is checked, and the coordinate (x,y) is mapped to the map array (Array). ) (505). The map array is a coordinated monitoring area indicated by a map, and individual positions of the plurality of fire detectors 200 installed at regular intervals in the monitoring area become one coordinate (x,y). In addition, each coordinate is initially set to a display value that is classified according to each state, for example, initialization (0), fire (1), rescuer (2), exit or emergency exit (3), evacuation route ( 4), can be optimally divided into progress indicators (5) and the like.

Subsequently, the operation server 301 stores the coordinates (x,y) in which the fire occurred in a separate fire array (507), checks the location of the rescued person, and displays the coordinates of the rescued person on the map array (509) The coordinates are stored (511). Subsequently, the operation server 310 executes an optimal recursive function that calculates an optimal path from the rescuer's location by referring to the stored fire occurrence location and the location of the rescuer, and monitors the optimal path generated by the optimal recursive function and the emergency screen.

In one embodiment, optimally, the recursive function executes step 601 for the left direction (x-1, y), and first determines whether the coordinates (x,y) are outside the preset range of the map array (603). If it is out of range, it is determined whether the evacuation route is correct (605).

If the direction in which the optimal recursive function is executed does not deviate from the range of the map array and the evacuation route (4) is correct according to the coordinate division display value, the coordinates are stored in the route array (607), and the division of the coordinates is displayed. After changing the value to the optimal progress indication (5), the optimal progress indication is displayed in the map array coordinates.

Subsequently, when the optimal recursive function execution result arrives at the doorway (611), the optimal path from the rescuer's location to the doorway is stored in the optimal array (613), and to the rescuer's original position to create another optimal path. After returning and returning the map array coordinates changed to the optimal progress display 5 to the evacuation route 4, optimally recursive functions (x+1, y) are sequentially executed.

On the other hand, if it is determined that all the entrances have been found (617) after the operation 615 is performed, the operation server 310 optimally ends the execution of the recursive function.
