Fire monitoring system for buildings

Abstract

A fire monitoring system for a building includes a video acquisition system, a monitoring center and a control module; the video acquisition system is used for acquiring video images in a building inreal time and transmitting the video images to the monitoring center; the monitoring center is used for filtering the received video images and performing flame target image detection according to theprocessed images, extracting image features in the detected flame target image and performing identifying, comprehensively determining whether the image is a flame, and allowing the control module tocontrol alarms in the building to alert and allow a sprinkling device to sprinkle water to put out the fire when it is determined that the image is the flame. The invention has the beneficial effectsthat the background subtraction method and the color feature based smoke pixel judgment method are combined to extract the smoke target image from the acquired video images; the accuracy of smoke target image extraction is improved; and a foundation is laid for the subsequent image feature extraction and recognition.

Description

technical field [0001] The invention relates to the field of forest building safety monitoring, in particular to a fire monitoring system for buildings. Background technique [0002] With the continuous increase of China's population and the continuous development of China's urbanization, centralized housing has become the trend of urban development. Due to people's lack of fire safety awareness and the existence of some flammable materials, fires occur frequently, and fires have become an incidence rate. Disasters with high risk, great harm and heavy loss. For fires, people began to shift from passive fire fighting to active monitoring and prevention, which greatly reduced casualties and property losses. [0003] Aiming at the shortcomings of traditional building fire detection and prevention, the present invention provides a building fire monitoring system based on image processing, which collects video images in the building in real time through cameras installed in the ...
