Apron thunder and lightning security protection system and method

Abstract

The invention provides an apron thunder and lightning security protection system and method. The apron thunder and lightning security protection system comprises an information collection module, an information processing module, a thunder and lightning early warning module and an information release module which mutually communicate, wherein the information collection module is used for collecting atmospheric electric field intensity data information and thunder and lightning positioning data information of a target apron; the information processing module is used for obtaining a first thunder and lightning prediction result according to the atmospheric electric field intensity data information, the thunder and lightning positioning data information and a preset graded early warning model; the thunder and lightning early warning model is used for outputting the first thunder and lightning prediction result, displaying a thunderstorm cloud cluster data set and auxiliary data corresponding to the first thunder and lightning prediction result, judging whether to generate a thunder and lightning early warning instruction or not according to the first thunder and lightning prediction result, the thunderstorm cloud cluster data set and the auxiliary data, and if so, sending the thunder and lightning early warning instruction to the information release module; and the information release module is used for releasing the thunder and lightning early warning instruction. The apron thunder and lightning security protection system can perform accurate and reliable thunder and lightning security protection on the apron.

Description

technical field [0001] The invention relates to the technical field of lightning early warning, in particular to an apron lightning safety protection system and method. Background technique [0002] Lightning is a strong discharge phenomenon in nature, and its occurrence is inevitable. Lightning is the weather phenomenon that has the greatest impact on the safe operation of civil aviation. It will seriously threaten the personal safety of personnel on the ramp, affect flight take-off and landing, and the efficiency of airport operations. The working environment of apron workers is exposed, especially those who work in an open environment. If they do not take correct and effective lightning protection measures when encountering lightning weather, lightning strike death accidents may occur. In August 2013, the cleanliness personnel of the business apron of Capital International Airport were struck by lightning while working on site, and died after rescue efforts failed. In t...

Problems solved by technology

[0004] However, the "30 / 30 rule" relies too much on the judgment of the field personnel

Weather radar data will have strong echoes only after the formation of precipitation particles, but the relationship between precipitation and lightning is not a simple correlation, and the probability of misjudgment is high. Although the safety of employees has been guaranteed to a certain extent, due to Prolonged shutdown impacts airline operations

The spatial scale of satellite data is very large, up to thousands of meters, but the temporal and spatial resolution of satellite data currently available is relatively coarse, and its role in lightning nowcasting is still limited. Another type of lightning protection for aircraft apron operations The technical solution of the method mainly relies on the installation of lightning rods for protection, and lacks the trigger conditions for executing the pre-planned actions, and at the same time, it will cause safety hazards for the take-off and landing of the aircraft

Moreover, the harm of lightning to ground operations is divided into two types: direct lightning strikes and induced lightning strikes. The actual principle of the lightning rod is to "attract" lightning and directly hit the lightning rod. In the process, a large amount of induced lightning will be released. In practice, outdoor workers Most of them are injured by induction lightning, that is to say, none of the existing technologies can provide accurate and reliable lightning safety protection for the apron
