Unmanned aerial vehicle device and method for monitoring fire point of coal gangue mountain

Abstract

An unmanned aerial vehicle device and a method for monitoring a fire point of a coal gangue mountain. The UAV device includes a flight control unit, a ground base station, a UAV carrier, a UAV-mountedinfrared thermal-imaging module, a UAV-mounted visible light camera module, a fire hazard recognition software module, a synchronous trigger software module, an image processing module, an image transmission software module, a data storage module, a positioning module, a battery, and a wireless communication module. The UAV device can overcome defects in single technology. The device can gradually shrink a range from large to small and accurately determines the center and temperature value of a fire point, thus supplying an evidence for fire extinguishing work. The device has important significance in the field of monitoring fire point of the coal gangue mountain and has excellent commercial prospect.

Description

technical field [0001] The invention relates to the field of coal gangue hill ignition point monitoring and management equipment, in particular to an unmanned aerial vehicle device and method for monitoring the coal gangue hill ignition point. Background technique [0002] As the most important energy source, coal has always been valued, and a large amount of mining is maintained. Coal gangue is an associated combustible material in coal mining, and its output accounts for about 10% to 20% of coal output, with an annual output of about 350 to 700 million tons. . Due to the low comprehensive utilization rate of coal gangue in my country, the accumulation of coal gangue is inevitable. At present, there is a large amount of gangue dumps in my country, with an accumulation of 5 billion tons. The accumulation of coal gangue has not only caused serious pollution to the environment of the mining area, but also is prone to ecological disasters such as spontaneous combustion, explo...

AI Technical Summary

Problems solved by technology

[0004] First, rely on experience to roughly determine the scope of the fire. This kind of construction often leads to serious waste of materials, the fire point cannot be accurately determined, and it is very easy to cause "blowout" accidents during the grouting process; second, surface temperature measurement. The method can only preliminarily determine the abnormal high temperature area, but cannot determine the location of the ignition point; third, the internal temperature measurement, the temperature measurement depth of this method is not accurate, and can only determine the ignition range, but cannot determine the center of the ignition point

The currently used temperature measurement method is single, the detection efficiency is low, and the determination accuracy of the ignition point is low.

[0005] Aiming at the disadvantages and insufficiencies of the above technologies that cannot accurately determine the center position of the ignition point and the ignition range, a comprehensive temperature measurement method is studied, including surface "point temperature measurement method", "panoramic temperature measurement method" and "comprehensive determination method of ignition point", etc. , it is particularly necessary to accurately determine the central position of the ignition point, the ignition range, and the temperature gradient
