According to the embodiments of the invention, a method and system for detecting the average electric field in atmosphere are provided. An unmanned aerial vehicle receives the unmanned aerial vehicle control command sent by an unmanned aerial vehicle control module at an operating platform and controls the unmanned aerial vehicle to reach a to-be-measured electric field. The metal tip that controls the unmanned aerial vehicle's atmosphere average electric field sensor is placed in the to-be-detected electric field. The voltage value and the threshold electric field intensity are obtained. The position, the time information of the unmanned aerial vehicle and the basic weather elements from an environment detection module are obtained. The voltage value, the threshold electric field intensity, and the position, the time information of the unmanned aerial vehicle as well as the basic weather elements experience analog-to-digital conversion to obtain their corresponding digital signals and to obtain the average electric field value of the atmosphere. The average electric field value of the atmosphere and the digital signals are transmitted to the signal receiving module at the operating platform. The signal receiving module receives the average electric field value of the atmosphere and the digital signals and transmits them to the display interface at the operating platform. The method of the invention raises the controllability, the stability and reliability of average electric field detection of air atmosphere.
Description
technical field [0001] The invention relates to the technical field of space environment detection, in particular to a method and system for detecting an airborne atmospheric average electric field. Background technique [0002] Lightning is a strong discharge phenomenon that occurs in the atmosphere. It can generate high current and strong electromagnetic radiation. It is one of the top ten electronic hazards in nature, often causing disasters such as forest fires and oil depot explosions. In order to conduct an in-depth study of the lightning phenomenon, it is necessary to understand the electrical characteristics of the thunderstorm cloud, and the average electric field intensity of the atmosphere is the most important parameter, which determines whether the lightning discharge can be initiated and transmitted. [0003] The traditional detection method of atmospheric average electric field in the air is to generate induced charges in the atmospheric electric field through...
