ASTROHN automatic fire detection system
Early fire detection is a key objective of modern fire protection systems. One of the most promising areas for the development of fire detection tools is continuous monitoring of territories in several spectral ranges. The advantages of such monitoring are the possibility of detecting a fire in open extended objects, in its initial stage with the exact determination of the coordinates of the fire source.
The engineers of ASTROHN Technology Ltd have developed a hardware-software complex for remote automatic fire detection. The complex has a built-in unit that analyzes the multispectral image from the sensors in the visible range (0.5-0.8 µm) and thermal imaging ranges (3-5 µm and 8-12 µm). The complex provides continuous surveillance and automatic fire detection in a radius of up to 5 km with a 360-degree all-round visibility. After receiving confirmation of fire, data is transmitted via fiber optic channels, or via mobile communications. The multispectral complex consists of a color digital video camera and matrix microbolometric uncooled thermal imaging photodetectors on ASTROHN-64017D detectors developed by ASTROHN Technology Ltd and installed in a common case. The images in the visible and thermal ranges are combined for analysis.
Testing ASTROHN complex
In October 2019, the complex was tested. The ability to detect open flames of 2×2 meters at distances of 5000 meters or more was confirmed.
During field tests of the system, open fire (temperature above 1500 K) was confidently detected at a distance of up to 5000 meters.
The complex is designed for early fire detection at long facilities, industrial enterprises, transport infrastructure facilities, in forestry and agriculture.
