Abstract

An optical acoustic thunder and lightning detecting process and a detector. The method comprises following steps: setting an optical acoustic thunder and lightning detector to make a lens of an image collector of the optical acoustic thunder and lightning detector face to the sky and the lens light axis of the image collector vertical to the horizontal plane; collecting the image with thunder and lightning image with the image collector, displaying on the image collector; detecting the azimuth of the thunder and lightning from the image based on the position of the thunder and lightning in the image. The detector can detect the distance and orientation of the thunder and lightning in the detecting visual range, acquire the image of the thunder and lightning and acquire the thundering sound by the sound collector with high detecting and positioning accuracy. The detecting steps are simple, detecting result is accurate and the thunder and lightning positioning problem is solves with low costs.

Description

technical field [0001] The invention relates to a device and a detection method for detecting lightning distance and azimuth within visual range. Background technique [0002] When lightning occurs, a huge return current and electric pulse radiation will be generated. Therefore, lightning location detection is directly related to the safety of air vehicles, and is an important reference data for aircraft flight and spacecraft launch. In addition, for people who are often outdoors, it is also a key to correctly assess the distance between lightning and lightning. very important thing. Traditional lightning locating equipment includes magnetic direction detectors and time difference detectors, which have a range of hundreds of kilometers and can record lightning occurrence time, location, intensity, polarity and other indicators, but the above-mentioned measuring devices need to be equipped with multiple Only the instrument can complete the measurement, which has the disadva...
