Abstract

The invention discloses a system for integrally, synchronously and comprehensively observing lightning electromagnetic signals, wherein the system comprises an integrated detection antenna device, a receiver and a data collection control device, wherein the integrated detection antenna device is used for detecting the electromagnetic field change generated by lightning, the time information and the space information of a detection position, and transmitting the electromagnetic field change signal and the time and space position information to the receiver; the receiver is used for receiving the electromagnetic field change signal and the time and space position information transmitted by the integrated detection antenna device, processing and transmitting the information to the data collection control device; and the data collection control device is used for real-time collecting the data processed by the receive, performing waveform display and storing the data. The system for integrally, synchronously and comprehensively observing lightning electromagnetic signals disclosed by the invention can synchronously and comprehensively detect the electric field speed change information and three-dimensional magnetic information of lightning; simultaneously, by the application of integration technology, the time and space consistency of the detection data is relatively high; and the observation system has the advantages of integration and portability.

Description

technical field [0001] The invention relates to the technical field of meteorological observation, in particular to an integrated synchronous comprehensive observation system for lightning electromagnetic signals. 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. . [0003] The characteristics of lightning electromagnetic field can reflec...
