Passive millimeter wave invisible fire source detection system

Abstract

The invention relates to a passive millimeter wave radiation detection-based invisible fire source detection system, which detects invisible fire sources in a target area by detecting passive millimeter wave radiation in the area and can be used for urban firefighting and forest fire prevention. In the invention, based on the characteristics of the non-electrolyte material penetrability of millimeter waves and the difference between millimeter wave radiation intensities of fire sources and non-fire sources, radiation intensity is acquired and the actual average temperature range in the target area is inversed by detecting the millimeter wave radiation in the target area; a temperature sensor acquires on-site temperature and on-site temperature parameter, and the normal average temperature range of the target area without any fire source is calculated by a preset model; and the actual temperature range detected in the target area and the normal average temperature range calculated by the model are compared, and the detection of the invisible fire sources in the detected target area can be realized at last.

Description

technical field [0001] The invention mainly relates to a hidden fire source detection system based on passive millimeter-wave radiation detection, especially a detection system for fire sources, especially hidden fire sources, by using the millimeter-wave radiation characteristics and penetrating properties of fire sources. Wave radiation detection and application fields. Background technique [0002] Fire source detection technology is one of the effective means for humans to rely on science and technology to fight against fire. From the 1840s to the 1940s, in the long 100 years, heat detectors dominated, and the automatic fire alarm system was in its infancy. The earliest fire source detection technology was the heat detector developed by the British in 1890, which created a precedent for fire source detection technology in history. The fire detection technology in this period is mainly based on the temperature signal collected by the temperature detector to determine wh...

Problems solved by technology

[0005] In the above-mentioned infrared fire source detection system, visible light video surveillance system, or smoke detection system, it is difficult to detect the concealed fire source that was once blocked

In the forest fire source detection system, since neither infrared rays nor visible light can penetrate tall and dense forests, it is impossible to effectively detect tiny fire sources in them.

But in the city, due to various walls, panels, windows, indoor furniture, etc., we cannot find the fire source behind it, especially when firefighters are extinguishing the fire source, because the hidden fire source cannot be found in time. , can lead to very serious consequences
