All-in-view lightning event observation system and method

Abstract

The invention relates to an all-in-view lightning event observation system and an all-in-view lightning event observation method. The system may comprise a shooting device, a tank body, a temperature control device, a light shading device, a control module, a power module, a sensor, a data acquisition device, a global positioning system (GPS) antenna, a GPS time service module and a processing unit, wherein the shooting device can shoot an all-in-view digital image and directly transmit the all-in-view digital image to the processing unit; and the processing unit continuously acquire corona current by the data acquisition device, judges whether an observed range has thunderstorms or not, starts the light shading device to enter a lightning channel image shooting mode if the observed rangehas the thunderstorms, and stops the light shading device after the observation is finished to protect the shooting device when the observed range does not have the thunderstorms. The system simultaneously records the GPS time of a lightning event and the waveform information of corona current change produced by the lightning event, judges a lightning type and the polarity of cloud-to-ground lightning, can realize the automatic light shading of the shooting device and automatic control over the working environment temperature of the shooting device in the thunderstorms, and also can work in afield environment stably and reliably for long.

Description

technical field [0001] The present invention relates to lightning observation, and more particularly to an observation system and method for lightning events within a full field of view. Background technique [0002] Lightning (lightning) is a spectacular weather phenomenon that occurs in the atmosphere. Accompanied by transient high current, high voltage and strong electromagnetic radiation, it often causes major disasters and accidents, not only causing casualties, but also causing serious damage to aerospace, aerospace, National defense, communications, electronics industry, chemical petroleum, post and telecommunications, transportation, forestry and other industries have caused serious economic losses. According to incomplete statistics, the average annual casualties in China due to being struck by lightning exceeds 1,300, and there are about 50 accidents in which the disaster loss caused by lightning exceeds 1 million yuan. With the rapid development of social economy...

Problems solved by technology

However, so far, there is no equipment that can automatically simultaneously acquire digital images of lightning channels in the full field of view and information such as the time, type (cloud flash, ground lightning) and polarity of lightning in the image, and there is no suitable equipment that can Observations have accumulated rich data for evaluating the detection efficiency and positioning accuracy of existing lightning location systems, which greatly limits the effective application of lightning location data
