Very-low frequency all-lightning positioning system

Abstract

The invention relates to a very-low frequency all-lightning positioning system comprising at least four lightning positioning monitoring sites. A very-low frequency lightning radiation receiver, a computer and a GPS clock module are arranged in each lightning positioning monitoring site. The lightning positioning monitoring site continuously catches lightning pulse wave shapes and arrival absolute time thereof without intervals; the Internet realizes the transmission of each site data, a lightning electric field is utilized to change time difference that the radiation pulse arrives at each site, and computer software used for analyzing and processing the pulse is utilized to carry out two-dimension positioning and three-dimension positioning on a lightning discharge event and identify a discharge type. Under the cooperation of the hardware and the software, the system can be used for accurately determining the statistical properties of lightning frequency, discharge type and lightning parameter in an area and can carry out prewarning on thunder activities.

Description

technical field [0001] The invention relates to meteorological observation equipment, in particular to a very low frequency full lightning positioning system. Background technique [0002] Lightning is one of the 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 impact caused by it are diff...

Problems solved by technology

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 impact caused by it are difficult to estimate. It has brought great difficulties to its research, forecast and prevention

In the existing technology, more attention is paid to the detection of flashback strikes, and there is no effective technology for the detection of lightning activity in the cloud and the identification method of lightning discharge events
