Full-lightning positioning system with combination of very-low frequency and very-high frequency

Abstract

The invention relates to a full-lightning positioning system with combination of very-low frequency and very-high frequency (VHF). The full-lightning positioning system is characterized by comprising at least four lightning positioning monitoring stations which are respectively provided with a very-low frequency lightning radiation receiver, a very-high frequency lightning radiation receiver, a GPS receiver and an industrial computer; the station utilizes time reference provided by the GPS receiver and obtains the time and waveform that the change pulse of a lightning electric field and VHF radiation pulse reach all the stations, utilizes the industrial computer to preprocess the obtained waveform data, then transmits the obtained data in real time to the industrial computer for analyzing and processing the pulse waveform by an internet, and realizes real-time monitoring and three-dimensional positioning to lightning discharge events. Under the matching of the above hardware and software, the system can be used for determining the quantity, types, characteristic parameters and statistical characteristics of lightning discharge events occurring in a specified area, and carries out monitoring and early warning to the activities of thunder and lightning.

Description

technical field [0001] The invention relates to meteorological observation equipment, in particular to a very low frequency and very high frequency full lightning positioning system. Background technique [0002] Lightning is one of the most serious natural disasters, which can cause fires in forests and oil depots, cause failure or damage to power supply and communication information systems, and pose a major threat to aerospace, mines, and some important and sensitive high-tech equipment. After the 1980s, the damage caused by lightning has increased significantly, especially in fields closely related to high-tech, such as aerospace, national defense, communications, electric power, computers, and electronics industries. VLSI has greatly increased the probability of being struck by lightning; according to conservative estimates, the direct economic loss caused by lightning damage in my country exceeds hundreds of millions of yuan each year, and the indirect economic loss and...
