Explosive TNT equivalent measuring system and measuring method based on unmanned aerial vehicle

Abstract

The invention discloses an explosive TNT equivalent measurement system and measurement method based on an unmanned aerial vehicle, and aims to solve the problems of complex erection process and poor measurement precision of an optical measurement method and the problems of electromagnetic interference, difficult wiring and the like of an electrical measurement method. The measuring system is composed of background cloth, a platform, to-be-measured explosives, an unmanned aerial vehicle, nails and a remote control exploder. The background cloth is marked with scales, the platform is arranged in the center of the background cloth, and the explosive to be tested is placed on the platform. The unmanned aerial vehicle is provided with a camera and hovers over the explosive to be tested. The background cloth is marked with measuring scales and direction lines. The method for measuring the TNT equivalent of the explosive comprises the following steps: firstly, assembling the measuring system, recording an image by the camera, and igniting the explosive to be measured; reading a picture in the camera after the explosion is finished; and processing the picture to obtain a TNT equivalent test result. The device is simple, does not need power supply, is convenient to arrange and can be repeatedly used; by adopting the method disclosed by the invention, the accurate equivalent TNT equivalent of the explosive to be detected can be quickly and conveniently obtained.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a measurement system for measuring the TNT equivalent of explosives to be tested through aerial photography of an unmanned aerial vehicle. Background technique [0002] TNT equivalent is an important parameter of explosives, which plays an important role in the prediction and evaluation of explosive damage effects and the protection of explosive shock. For many self-made explosives and improved explosives, the TNT equivalent can only be given after the explosion experiment is measured. Therefore, it is of great significance to establish a new type of explosive TNT equivalent measurement system. [0003] When the explosive explodes in the air, high-temperature, high-pressure, and high-speed explosion products are generated instantly, and the surrounding air is directly affected by the explosion products, which will be strongly compressed to form an initial shock wave and pr...
