specific Embodiment approach

[0020] figure 1 A general block diagram of the invention is shown. The system of the invention is divided into four parts: atmospheric electric field detection device, data processing device, induction device and lightning protection circuit.

[0021] attached figure 2 The specific connection diagram of the whole system is given. The atmospheric electric field detection device is used for real-time detection of the analog quantity of the atmospheric electric field near the device, and its internal design is detailed in image 3 . After the atmospheric electric field detection device collects the analog value of the atmospheric electric field, it outputs the value to the data processing device. The data processing device has two main functions: one is to receive the analog quantity of the atmospheric electric field, and convert it into a digital quantity through the analog / digital converter, that is, the ADC module; the other is to send microwaves to the microwave transmit...

Abstract

The invention provides an active type microwave induction lightning protection system. The microwave is utilized to serve as uplink guide, and then the aim of actively guiding the lightning into the ground is achieved. The active type microwave induction lightning protection system is mainly composed of an atmospheric electric field detection device, a data processing device, an induction device and a thunder and lightning protection circuit. The atmospheric electric field detection device is mainly used for detecting the field intensity of an atmospheric electric field in real time; the data processing device is connected with the atmospheric electric field detection device and the induction device; the induction device comprises a lightning arrester, a microwave generation circuit, an antenna and a grounding device; the thunder and lightning protection circuit protects the system from being damaged by lightning currents. Compared with a traditional lightning protection mode, the system solves many problems existing in the traditional lightning protection process, and a lightning protection method which is more active, more reliable and wider in protection range is provided.

Description

technical field [0001] The invention relates to the field of lightning protection and lightning protection engineering, and particularly designs an active microwave lightning protection system. Background technique [0002] Lightning protection and lightning protection technology can be roughly divided into conventional lightning protection methods and unconventional lightning protection methods. [0003] The conventional lightning protection method is also called the traditional lightning protection device. It can be divided into anti-direct lightning, anti-inductive lightning and comprehensive lightning protection. The lightning protection device against direct lightning strike generally consists of three parts. That is, lightning receptors, down conductors and grounding bodies; among them, lightning receptors are divided into lightning rods, lightning conductors, and lightning protection nets. The most commonly used lightning protection device is the lightning rod that...
