DEVICE FOR PC CONTROL AND GUARANTEED PREVENTION OF INFORMATION STEALING FROM ITS HARD DISK Russian patent published in 2019 - IPC G08B13/08 G08B21/18 

FIELD: physics.

SUBSTANCE: invention relates to the field of PC control equipment in a secure room and guaranteed prevention of information theft from its hard disk. Disclosed is a PC control device, comprising a power supply unit comprising a transformer, to which a diode bridge with a capacitor is connected; to the power supply unit the reed relay is installed, which is installed on the entrance door into the room with the personal computer and reacts to the door opening of the room with the personal computer, in series with parallel connection of LED signalling illegal infiltration into room with PC, and buzzer, which operates simultaneously with lighting of said light-emitting diode; to the power supply unit a reed switch is installed, which is installed on the PC system unit cover and reacts to the PC system unit opening, in series with the LED parallel connection, which signals the PC system unit opening, and buzzer, which operates simultaneously with lighting of said light-emitting diode; solenoid is connected to power supply unit in series with light-emitting diode, which indicates that information on hard disk is destroyed, and button for destroying information on hard disk, wherein solenoid is installed in PC over rigid disk and creates powerful magnetic field, which destroys information on hard disk, when button is pressed to destroy information on hard disk; microcontroller connected to power supply unit in series with parallel connection of LED, signalling illegal connection to PC along local area network, and a buzzer, which is activated simultaneously with lighting of said LED, wherein microcontroller monitors unauthorized connection to PC on LAN; wherein light-emitting diode, which signals illegal infiltration into room with PC, light-emitting diode, which signals illegal connection to personal computer via LAN, light-emitting diode, which signals opening of system unit of personal computer, are located on LED panel "DANGER OF HAZARD"; wherein all elements of the device, except for reed switches and solenoid, are located in the observation point, which differs from the room with the PC.

EFFECT: technical result is realization of light and sound alarm of illegal infiltration of malefactor into room with personal computer; performing light and sound alarm when connected to a PC over a local area network; performing light and sound alarm in unauthorized opening of a PC unit; possibility of remote destruction of information on a personal computer hard disk in case of attempted capture by an intruder.
