Multi-fire-source identification method based on automatic tracking and positioning jet fire extinguishing device

Abstract

The invention discloses a multi-fire-source identification method based on an automatic tracking and positioning jet fire extinguishing device. The method comprises the steps: firstly, fire alarm conditions in a protected scope are real-timely monitored by an ultraviolet fire disaster detector in the jet fire extinguishing device, under triggering of fire disaster early warning signals, a video image acquisition module in the fire extinguishing device is started to identify and confirm fire disaster signals, and all flame targets and maximum ignition points thereof are accurately identified through target fusion and segmentation and other ways; and fire disaster positions are accurately positioned by using a computer vision technology, and finally a multi-target fire extinguishing path is planned. The invention aims to provide the method which can automatically identify fire disasters when the fire disasters break out, so as to achieve the purpose of real-time extinguishing of all the fire disasters in the protected region in the one-time scanning working process.

Description

technical field [0001] The invention relates to the technical field of fire detection, in particular to a multi-fire source identification method based on an automatic tracking and positioning jet fire extinguishing device. Background technique [0002] In recent years, my country has achieved certain results in the research of fire monitoring in tall and large spaces. Among them, automatic fire monitors, as an intelligent fire extinguishing system integrating detection, positioning, and fire fighting, have broad development prospects. In some unguarded key protection areas, the technical requirements for fire monitors are getting higher and higher. Finding an efficient automatic fire extinguishing method will become an important direction for the development of fire monitors in the future. [0003] In recent years, with the development of various fire sensor technologies, most of the automatic tracking and positioning jet fire extinguishing devices on the market are based ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, with the development of various fire sensor technologies, most of the automatic tracking and positioning jet fire extinguishing devices on the market are based on ultraviolet flame sensors and infrared flame sensors. These sensors are generally sensitive to sound, electromagnetic waves and vibrations. There is a certain false alarm rate, and the use environment is subject to certain restrictions

When the fire extinguishing device is close to the flame or there are multiple fire sources in the protected area, there are defects that the fire source cannot be accurately detected and located, and the size of the fire cannot be judged at the same time.

This is mainly due to the fact that most of these devices use infrared energy pyroelectric method for positioning detection, but when the flame energy is too strong, the infrared pyroelectric device is oversaturated and cannot accurately locate the flame energy
