Description

Real-time automatic fire extinguishing system and fire suppression method using the same}

This applied invention relates to a real-time fire extinguishing system, and more specifically, to a system that detects fire at all times with an unmanned system and automatically sprays fire extinguishing agent to the ignition point when a fire occurs to suppress the fire at an early stage.

Fire damage increases exponentially over time. Therefore, it is very important to extinguish the fire in the early stage of the fire.

Accordingly, it is desirable and required to provide fire extinguishers in preparation for fire outbreaks. However, in the case of a general fire extinguisher, not only does the user have to purchase and keep the fire extinguisher separately, but the extinguishing agent must be sprayed only by a person operating the extinguisher, so the user must take risks in the event of a fire, and it is useless if the fire extinguisher is difficult to access due to the flame. There is a downside to this.

Recently, extinguishing objects are not limited to simple existing buildings or their internal devices and records, but are increasingly becoming more diverse. This is due to the diversification and integration of auxiliary facilities due to the enlargement of buildings and high-rise buildings. As auxiliary facilities become more diversified and integrated, it is difficult to quickly suppress fires that occur with conventional fire extinguishing facilities.

Conventional fire detection systems often use differential detectors that detect heat through air expansion due to heat, but when the temperature around the detector increases, the fire has already spread to some extent, so it has the disadvantage of being vulnerable to initial fire detection. .

In addition, smoke detectors such as photoelectric detectors or ionization detectors are being used, but it is difficult to generalize them due to economic problems. Smoke may not be detected in cases where ventilation is good or the diffusion of external air is difficult, and it is very sensitive to humidity. It is sensitive and has the problem of malfunctioning due to dew, etc.

In the case of flame detection sensors, since they use an ultraviolet detection method, there is a disadvantage that the sensitivity may decrease due to ultraviolet rays being absorbed by other floating substances, and there is a high possibility of false detection, such as reacting to welding light.

Accordingly, the need for a system that can detect a fire at the very early stage and quickly extinguish the fire while reducing malfunctions by solving the problems of these prior technologies has increased.

The present invention seeks to provide a fire extinguishing system designed to detect a fire in the very early stage using a plurality of sensors, accurately determine whether a fire has occurred using an artificial intelligence algorithm, and automatically extinguish the fire in real time.

The present invention is intended to achieve the above-mentioned object, and the fire extinguishing system according to an embodiment of the present invention includes at least one infrared sensor, a thermal imaging camera, and a visible light camera, and detects a fire in an area of interest through the sensor and camera. A monitoring unit that monitors the fire, a fire extinguishing unit that includes a nozzle that sprays fire extinguishing agents and extinguishes the fire, a judgment unit that determines whether a fire has occurred and the ignition point based on data obtained from the monitoring unit, and a control unit for transmitting and receiving to the manager terminal. It includes a control unit that controls the operation of the communication unit and the fire extinguishing unit, and the fire extinguishing unit is connected to the nozzle and further includes a storage unit in which fire extinguishing agent is stored. The control unit, when it is determined that a fire has occurred by the determination unit, moves to the ignition point detected by the monitoring unit. The up and down and left and right angles of the nozzle can be controlled so that fire extinguishing agent is sprayed.

According to the fire extinguishing system according to this invention, it has the advantage of reducing damage from fire by more accurately determining whether a fire has occurred in the very early stages, accurately determining the ignition point, and automatically extinguishing the fire in the early stage of the fire. .

Accordingly, fire can be detected in a variety of ways, such as heat, gas, and smoke, in addition to flame or flame.

If necessary, the monitoring unit 110 may include a two-wavelength infrared sensor and a three-wavelength infrared sensor. The monitoring unit 110 uses a 2-wavelength infrared sensor and a 3-wavelength infrared sensor simultaneously to more accurately determine whether there is a fire or the point of ignition. A two-wavelength infrared sensor is a sensor that detects a fire using two different wavelengths, and a three-wavelength infrared sensor is a sensor that detects a fire using three different wavelengths. Since these infrared sensors can use various previously disclosed sensors, a detailed description thereof will be omitted.

The fire extinguishing unit 120 is a component for extinguishing a fire and may include at least one of a water extinguisher, a carbon dioxide extinguisher, a powder extinguisher, a foam extinguisher, and a Halon extinguisher, and is configured to extinguish the fire by spraying extinguishing material. corresponds to If necessary, the fire extinguishing unit 120 includes a nozzle that sprays fire extinguishing agent.

In other words, a flame is detected based on information obtained from sensors and cameras, and the type of flame and whether the flame is a fire are determined. More specifically, the determination unit 130 may determine that the flame detected by the monitoring unit 110 is a flame generated from welding, and through this, the determination unit 130 may determine that a fire has not occurred.

If necessary, the determination unit 130 can predict the direction of fire progress through an AI algorithm. The determination unit 130 can predict the direction of fire progress and extinguish the fire early by spraying fire extinguishing agent in the direction of fire progress.

Artificial neural network models include Deep Feedforward Network (DFN), Recurrent Neural Network (RNN), Convolutional Neural Network (CNN), Deep Residual Network (DRN), Examples include Long Short-Term Memory (LSTM) neural network, Bidirectional Long Short-Term Memory (biLSTM) neural network, and transformer neural network.

The artificial intelligence model of the determination unit 130 may be implemented as a bidirectional LSTM neural network among the exemplified artificial neural network models. While the LSTM neural network includes only one LSTM layer, the bidirectional LSTM neural network includes two LSTM layers. Here, one LSTM layer uses the input in the forward direction, and the other LSTM layer uses the input in the reverse direction. Bidirectional LSTM neural networks have higher prediction accuracy than LSTM neural networks because they learn bidirectionally rather than unidirectionally.

The communication unit 140 of the fire extinguishing system can communicate with any external device and internal server, and more specifically, the communication unit 140 can perform transmission and reception with the administrator terminal. For example, the fire extinguishing system 10 may transmit fire information to the manager terminal 500-n through the communication unit 140 and obtain a manual control signal from the manager terminal 500-n.
