Fire flame video monitoring and early warning system and fire flame detection method

Abstract

The invention discloses a fire flame video monitoring and early warning system and a fire flame detection method. The fire flame video monitoring and early warning system comprises a network video CCD (Charge Coupled Device) camera, a video management module, a fire flame detection subsystem and an early warning subsystem. The fire flame detection method performs information integration of the static and dynamic features of fire flames and provides a fire judgment algorithm based on a neural network and D-S (Dempster-Shafer) evidence judgment, the algorithm can provide three early warning threshold values according to the magnitude of a fire, and the three early warning threshold values correspond to three levels of early warning modes, i.e. on-scene sound and light warning, remote short message warning and network warning. The invention provides the fire flame video monitoring system which monitors early small fire sources and judges the fire flame level on the basis of multi-feature information integration, and has the advantages of strong anti-interference capability, high space adaptability, high fire early warning accuracy and low false warning rate.

Description

technical field [0001] The invention belongs to the field of public safety and relates to a fire monitoring and early warning system, in particular to a fire flame video monitoring and early warning system and a fire flame detection method. Background technique [0002] Fire is a major hidden danger that threatens human existence. Especially in recent years, frequent fires have caused great loss of life and property to people. According to statistics, a total of 125,402 fires occurred in my country in 2011, resulting in 1,106 deaths and a direct economic loss of 1.98 billion yuan. In June 2011, a huge fire broke out in Shanghai, killing 58 people and causing a direct economic loss of 158 million yuan. Finding the fire source in time and taking effective fire-fighting measures to extinguish the initial flame can greatly reduce various losses. [0003] As the core component of the fire warning system, the fire detector has roughly experienced the development process from tem...

Problems solved by technology

In the video fire early warning technology, the fire flame detection method is the core. Although domestic experts have carried out some research and development work on the video fire flame detection method in recent years, the mature technology is rarely applied, and the corresponding products are rarely available.
