Embodiment Construction

[0035] Below, the specific implementation manners of the present invention will be further described in conjunction with the accompanying drawings.

[0036] The lightning monitoring method that the photoelectric signal conforms to includes the following steps:

[0037] 1) The light signal radiated by the ground flash discharge is received by the photocell, and the signal is amplified and filtered and then transmitted to the data acquisition module;

[0038] 2) The very low frequency electromagnetic pulse signal radiated by the ground lightning discharge is sensed by the antenna, and the signal is amplified and filtered and then transmitted to the data acquisition module;

[0039] 3) Accurate time information and longitude, latitude and height spatial position information of the detection site are collected by the GPS module, and the information is transmitted to the data acquisition module;

[0040] 4) The light signal and electromagnetic signal of lightning become digitized ...

Abstract

The invention relates to a method and a device for monitoring a lightning coincident with photo-electric signals. The method comprises the steps of synchronously sampling a radiated optical signal and a very low frequency electromagnetic signal when a lightning occurs in the manner of multi-station detection, synchronously recording a lightning time and a detection station position, sending the lightning data to a system host machine through a network, identifying the lightning through the system host machine, removing an interference signal, positioning, computing the lightning time and position, establishing a lightning information database, and providing an inquiry and statistics function. The device of the invention comprises a plurality of probes and one system host machine, wherein the probes comprise an optical signal amplification module, an electromagnetic signal amplification module, a GPS module, an AD module and a DSP module and the system host machine comprises hardware and software. The method and device of the invention can synchronously record the lightning optical signal and electromagnetic signal, can synchronously analyze through the photo-electric signal, are in favor of removing the interference signal, and can promote the precision of lightning identification and positioning. The monitoring step is simple and the positioning is accurate.

Description

technical field [0001] The invention relates to the field of lightning monitoring, in particular to a method and device for lightning monitoring based on photoelectric signal coincidence. Background technique [0002] Lightning is a super-intensive and instantaneous discharge phenomenon in the natural atmosphere. It is one of the ten most serious natural disasters announced by the United Nations "International Decade for Disaster Reduction", and has always caused serious harm to human production and life. Fields that are often affected by lightning include construction, power grids, communications, forestry, transportation, military settings, etc., especially microelectronics technology, information networks, and wireless communication equipment, which are widely used now, are more and more likely to be struck by lightning and cause heavy losses . Therefore, how to accurately monitor and forecast lightning has increasingly become an urgent problem for human beings to solve....
