Multi-path gateway electromagnetic pulse protection module for Ethernet

Abstract

The invention belongs to the technical field of strong electromagnetic pulse protection, and particularly relates to a multi-path gateway electromagnetic pulse protection module for the Ethernet. Theprotection module comprises a first transient suppression circuit, a decoupling resistor, a second transient suppression circuit and a shielding shell. The first transient suppression circuit and thesecond transient suppression circuit are connected in series. The output end of the first transient suppression circuit is connected with the input end of the decoupling resistor in series, the outputend of the decoupling resistor is connected with the input end of the second transient suppression circuit in series, and the first transient suppression circuit, the decoupling resistor and the second transient suppression circuit are fixed in the shielding shell. Compared with the prior art, a two-stage protection circuit of a gas discharge tube and a transient voltage suppressor is adopted, and strong electromagnetic pulses with shorter rising front edges can be filtered out more reliably. A standard RJ45 type Ethernet port is adopted, so that the compatibility is improved, and the installation and the use are more convenient.

Description

technical field [0001] The invention belongs to the technical field of strong electromagnetic pulse protection, and in particular relates to a multi-channel network port electromagnetic pulse protection module for Ethernet. Background technique [0002] On the modern military battlefield, the wide application of electronic warfare systems and electromagnetic pulse weapons, such as the emergence of high-power microwave weapons, ultra-wideband weapons, electromagnetic bombs, electromagnetic missiles, etc., coupled with electromagnetic sources such as natural lightning and electrostatic discharge, make automation intelligent The environment in which the system and associated communications systems operate has become more hostile. Communication systems play a pivotal role in modern warfare. In a strong electromagnetic pulse environment, the performance of sensitive equipment such as signal receivers may be reduced or failed, and the internal electronic circuits, components, and...

AI Technical Summary

Problems solved by technology

In a strong electromagnetic pulse environment, it may lead to the degradation or failure of the performance of sensitive equipment such as signal receivers, the misoperation of electronic circuits, components, and communication transmission inside communication equipment, and even burn or break down components.

[0003] At present, the Ethernet data lines of military electronic equipment and systems have been designed for electromagnetic compatibility, but none of them has been designed for electromagnetic pulse protection. The Ethernet data lines of military electronic equipment and systems are under the threat of strong electromagnetic pulse attacks at any time. Suffers damage from surges and interference voltages
