Электромеханическое импульсное устройство ударно-механического и электромагнитного воздействия

Abstract

FIELD: information technology. SUBSTANCE: invention relates to information security, wherein destruction of information is carried out based on both obtaining signals on unauthorised intrusion, and at desire of user. Electromechanical pulse device of impact-mechanical and electromagnetic action consists of ferromagnetic frame, inside of which there are coaxially arranged inductor, electroconductive armature and ferromagnetic head. One flat surface of electroconductive armature is connected to power disc. Head is made with sharpened tempered end directed towards digital information storage. Inside frame there are multiple levers, each of which consists of two opposite arms, separated by support. Flat end of head interacts with arm of lever, and power disc interacts with arm of lever. Supports of levers are fixed relative to detachable cover of frame. Inductor coil is wound on guide sleeve of head. Portion of surface area of power disc interacting with arm of lever, protrudes. To increase height of protruding part of power disc is equipped with pusher made in form of a ring. When producing a signal inductor is excited from a charged capacitive storage. Flowing pulse current in inductor excites magnetic field, destroying information in storage. Magnetic field of inductor excites eddy currents in electroconductive armature. Electrodynamic force thus generated causes displacement of latter together with power disc from inductor. Power disc via pusher acts on arm of levers, end of which moves in direction from inductor. Levers turn relative to fixed supports and ends of opposite arms of levers move in direction of inductor to apply force action on flat end of head. Head moves in direction of inductor, punching with its sharpened end digital storage. EFFECT: technical result is improved efficiency of protecting information stored on digital media in case of leakage due to impact-mechanical and electromagnetic effects.
