Fire hazard probe system and its fire hazard detection method

Abstract

The invention provides a fire detection system and a method thereof. The system comprises a video collection module, a flame judging module that extracts flame characteristic parameters from video images collected and carries out statistical analysis according to the flame characteristic parameters so as to calculate the flame probability of occurrence of a detection area, a smoke judging module used for extracting smoke characteristic parameters and carrying out statistical analysis according to the smoke characteristic parameters so as to calculate the smoke probability of occurrence of a detection area, a fire judging module that carries out fusion calculation according to the flame probability of occurrence and the smoke probability of occurrence so as to determine fire probability ofoccurrence, a fault judging module used for identifying fault information and an alerting module used for making a comparison between the probability of occurrence of flame, smoke and fire and a preset threshold value and sending out alerting information according to a comparison result. The fire detection system and the method of the invention can simultaneously realize the detection and alerting of flame and smoke, especially has very good identifying capability of the smoke at the initial period of fire and has the function of early alerting.

Description

technical field [0001] The invention relates to fire safety monitoring technology, in particular to a fire detection system and a fire detection method thereof. Background technique [0002] Over the years, large spaces (convention centers, stadiums, hangars, large warehouses, large factories, etc.), special buildings (traffic tunnels, petroleum and petrochemical production areas, explosive storage areas, museums, subways, train stations, hospitals, etc.) and Fire detectors in large outdoor venues (forests, parks and other public communities, etc.) have always been a problem of continuous exploration and research in the fire protection industry. [0003] The characteristics of a large space are: large space, generally as high as 20m or more, and a large floor area of ​​a single building; it is difficult to detect fires in the early stage. Concentration, temperature, etc. are difficult to respond quickly. For example, it takes a long time for smoke to reach a certain height ...

AI Technical Summary

Problems solved by technology

[0012] The principle is basically similar to the linear beam smoke detector, which is not suitable for places with high heights, and it is difficult to detect the rising smoke generated in the early stage of the fire;

[0013] Infrared light-emitting array installation is very inconvenient
