Abstract

SE DESARROLLA UN DETECTOR PARA SU EMPLEO EN SISTEMAS DE SEGURIDAD EN UNA ZONA DE CONTROL. EL DISPOSITIVO COMPRENDE UN CONJUNTO DE CIRCUITOS PARA FORMAR UN SISTEMA INICIAL DE CIRCUITO DE RESONANCIA (14) CON UNA FRECUENCIA DE RESONANCIA PRINCIPAL, EN UNA BANDA DE SECUENCIA PRIMARIA, FUERA DE LA BANDA DE DETECCION DE FRECUENCIA DEL SISTEMA ELECTRONICO DE SEGURIDAD. EL DETECTOR ES ACTIVADO, AL CAMBIAR LA FRECUENCIA RESONANTE DEL CIRCUITO DE RESONANCIA (14), A UNA FRECUENCIA SECUNDARIA, DENTRO DE LA BANDA DE DETECCION DE FRECUENCIA, MEDIANTE LA EXPOSICION DEL CIRCUITO RESONANTE, CON UNA FUERZA ELECTROMAGNETICA EN LA PRIMERA BANDA DE FRECUENCIA EN UN PREDETERMINADO NIVEL MINIMO DE ENERGIA, PARA PROVOCAR UN CORTOCIRCUITO EN UN COMPONENTE DE CIRCUITO PRIMARIO (C4). EL DETECTOR SE DESACTIVA CAMBIANDO DE NUEVO LA FRECUENCIA RESONANTE DEL CIRCUITO DE RESONANCIA (14) A UNA TERCERA FRECUENCIA RESONANTE DENTRO DE UNA BANDA DE TERCERA FRECUENCIA QUE SE ENCUENTRA ASI MISMO FUERA DE LA BANDA DE FRECUENCIA DE DETECCION MEDIANTE LA EXPOSICION DEL CIRCUITO DE RESONANCIA (14) CON UNA FUERZA ELECTROMAGNETICA DENTRO DE LA BANDA DE DETECCION DE FRECUENCIA O UN MINIMO NIVEL DE ENERGIA PREDETERMINADO, PARA LA PUESTA EN DE UN SEGUNDO COMPONENTE DEL CIRCUITO.
