Abstract

The invention discloses a lightning detection and positioning system and method, which relate to the technical field of meteorological detection. The system comprises an antenna unit, a receiver unit, a waveform characteristic extracting and processing unit and a monitoring and controlling unit, wherein the antenna unit is used for detecting an electromagnetic field variation signal while lightning happens, detecting a GPS satellite signal and transmitting the electromagnetic field variation signal and the GPS satellite signal to the receiver unit; the receiver unit is used for receiving the electromagnetic field variation signal and the GPS satellite signal; the waveform characteristic extracting and processing unit is used for extracting electromagnetic field variation signal waveform characteristic parameters in real time and analyzing the parameters to obtain a cloud ground flash identification result and a ground flash positioning result; and the monitoring and controlling unit is used for collecting and storing the waveform of the electromagnetic field variation signal in real time, marking the time of collecting the lightning waveform and displaying the position of the ground flash in a geographical information system in real time. The system and method disclosed by the invention, multifunctional single-station lightning detection and positioning of the lightning waveform collection and lightning strike-back positioning can be carried out.

Description

technical field [0001] The invention relates to the technical field of meteorological observation, in particular to a lightning detection and positioning system and method. Background technique [0002] Lightning is one of the most serious natural disasters in my country. Due to its characteristics of high current and strong electromagnetic radiation, it often causes forest fires, oil depot explosions, power supply interruptions, communication failures, equipment damage and other accidents, and it is easy to cause casualties. According to conservative estimates, thousands of casualties are caused by lightning disasters in my country every year, and direct economic losses exceed hundreds of millions of yuan. The resulting indirect economic losses and impacts are difficult to estimate. Lightning disasters have affected all walks of life and all aspects of life. . The way of being struck by lightning has also expanded from direct lightning strikes and overvoltage wave transmiss...
