Problems solved by technology

But today's computers, audio, and video equipment basically use DVI and HDMI digital transmission interfaces, and their electromagnetic radiation characteristics are completely different from those of VGA. larger
In addition, the existing equipment has a single function except that it cannot perform electromagnetic protection on the DVI and HDMI digital interfaces, which is inconvenient to use and difficult to comprehensively protect.

Abstract

The invention discloses an intelligent electromagnetic information protection system. The system comprises a main control module, a state detection module, a network communication module, a broadbandinterference information source generation module, a targeted comb-shaped information source generation module, a VGA interface module, a DVI interface module, an HDMI interface module, a power supplymodule, an output efficiency detection module, a power output control module, a multi-channel broadband power amplifier and an antenna. The power supply module, the network communication module, thestate detection module, the output efficiency detection module, the power output control module, the broadband interference information source generation module and the targeted comb-shaped information source generation module are all connected with the main control module. According to the system, interface electromagnetic information such as VGA, DVI, HDMI and the like can be automatically and respectively selected to be effectively protected, the interference modes of VGA, DVI and HDMI can be automatically and simultaneously started at high power, and effective electromagnetic protection can be implemented on important secret-related places, large-scale comprehensive display platforms and high-density interconnection interfaces.

Description

technical field [0001] The invention belongs to the technical field of information security, in particular to an intelligent electromagnetic information protection system. Background technique [0002] At present, domestic electromagnetic information protection equipment is mainly divided into two categories, namely, computer video-related jammers and electronic information protectors. The interference methods are based on the electromagnetic radiation characteristics of the VGA video interface, and are designed according to the technical specifications of the national standard BMB4-2000. Yes, in fact, the technical principle and technical implementation are basically the same, both based on electromagnetic spectrum suppression, but the power output is different. But today's computers, audio, and video equipment basically use DVI and HDMI digital transmission interfaces, and their electromagnetic radiation characteristics are completely different from those of VGA. larger. ...
