Abstract

EN UN SISTEMA DE SEGURIDAD PARA EQUIPO ELECTRICO Y ELECTRONICO, CADA PIEZA DEL EQUIPO DISPONE DE UNA UNIDAD DE SEGURIDAD (10) ACOPLADA A SU ENTRADA DE ENERGIA DE LA RED, Y ALMACENANDO UN CODIGO DE IDENTIDAD QUE ES UNICO PARA ESA PIEZA, Y CADA ENCHUFE (14) DE SALIDA DE LA RED INCLUYE UNA UNIDAD DE SEGURIDAD QUE ALMACENA UN CODIGO DE SEGURIDAD QUE ES UNICO PARA ESE ENCHUFE. UN ORDENADOR CENTRAL (30) SE ACTIVA DESDE LA RED, Y ESTA EN CONDICIONES DE ESCRUTAR LAS UNIDADES DE SEGURIDAD (10) DE LAS PIEZAS DEL EQUIPO SOBRE LA RED: LAS SEÑALES DE LA UNIDAD (10) DE SEGURIDAD ESCRUTADA ENVIAN HACIA ATRAS UN ACUSE DE RECIBO QUE ES DETECTADO POR LA UNIDAD DE SEGURIDAD DEL ENCHUFE (14) DE LA RED ASOCIADO, HACIENDO QUE LA UNIDAD DE SEGURIDAD ULTIMA ENVIE HACIA ATRAS SU CODIGO DE IDENTIDAD.IN A SECURITY SYSTEM FOR ELECTRICAL AND ELECTRONIC EQUIPMENT, EACH PART OF THE EQUIPMENT HAS A SECURITY UNIT (10) COUPLED TO ITS ENERGY INPUT FROM THE NETWORK, AND STORING AN IDENTITY CODE THAT IS UNIQUE FOR THAT PART, AND EACH PLUG (14) NETWORK OUTPUT INCLUDES A SECURITY UNIT THAT STORES A SECURITY CODE THAT IS UNIQUE FOR THAT PLUG. A CENTRAL COMPUTER (30) IS ACTIVATED FROM THE NETWORK, AND IS IN CONDITION TO SCRIPT THE SECURITY UNITS (10) OF THE EQUIPMENT PIECES ON THE NETWORK: THE SIGNALS OF THE SECURED UNIT (10) SEND BACK TO AN ACKNOWLEDGMENT RECEIVED THAT IT IS DETECTED BY THE SECURITY UNIT OF THE ASSOCIATED NETWORK PLUG (14), MAKING THE LAST SECURITY UNIT SEND BACK ITS IDENTITY CODE.
