Automatic positioning flame detection system for three-dimensional space

Abstract

The invention discloses an automatic positioning flame detection system for a three-dimensional space. The automatic positioning flame detection system comprises a front-end monitoring unit connected with a fire scene, a control center connected with the front-end monitoring unit as well as a firefighting linking unit connected with the control center. According to the automatic positioning flame detection system, image acquisition is carried out on the scene at different orientations by adopting more than two sensors in high-resolution infrared CCD (Charge Coupled Device) image type flame detectors; and intelligent fire identification processors are used for analyzing a video image by using a fire flame image identification algorithm and an image three-dimensional algorithm, capturing fire flame information of the scene, analyzing flame position, fire alarm information, the positions of the flame detectors and the flame orientation, transmitting the analysis result to a fire monitoring and managing platform and outputting a signal to an automatic fire alarming control host to the firefighting linking unit. The automatic positioning flame detection system has the characteristics of high positioning precision, long monitoring distance, great protection area and quick speed response and can better meet the requirement of great-space occasions on fire monitoring.

Description

technical field [0001] The invention relates to a fire extinguishing system, in particular to an automatic positioning flame detection system. Background technique [0002] With the rapid development of China's economic construction, the urban space is expanding more to the three-dimensional space, and large buildings are everywhere. At present, there are large public gathering buildings such as large exhibition halls, gymnasiums, large shopping malls, and passenger transport halls. Large factory buildings, warehouses, oil depots and other industrial buildings often have various types of large internal spaces. The ceiling of such large-space buildings can often be as high as 20-60 meters, and the internal diameter can reach hundreds of meters, which can accommodate tens of thousands of people. Although this type of building has the advantages of grandeur, small footprint, and many internal functions, its internal personnel are densely populated and the facilities are compli...

AI Technical Summary

Problems solved by technology

[0005] (1) The pipe network of the sprinkler device is complex, which will affect the aesthetics of the entire building

[0006] (2) The height of the water spray device is limited. If a large-scale fire occurs, the sprayed water will fall from a high place and often cannot reach the burning surface

[0007] (3) The sprinkler device cannot realize fixed-point firefighting, and sprays water to the protection area in an all-round way during firefighting, thus causing unnecessary water damage loss
