Abstract

UN METODO Y UN APARATO PARA DETECTAR LAS FALLAS DE UN SISTEMA DETECTOR DE IMPACTOS DE PUNTO UNICO QUE TIENE UNAS PLACAS DE AUTOVERIFICACION ELECTRICAMENTE CONDUCTORAS COLOCADAS DENTRO DEL DETECTOR PARA DESVIAR ELECTROSTATICAMENTE EL ELEMENTO DETECTOR DURANTE LA SECUENCIA DE AUTOVERIFICACION. LA DESVIACION DEL ELEMENTO DETECTOR ES IDENTICA A LA DESVIACION QUE TENDRIA LUGAR DURANTE UN CASO DE IMPACTO DIGNO DE UNA ACTIVACION REAL. EL TIEMPO DE RESPUESTA DESDE LA DESVIACION DEL ELEMENTO DETECTOR HASTA EL CAMBIO DE ESTADO DE UN INDICADOR DE ACTIVACION SE REGISTRA Y COMPARA CON UN TIEMPO DE RESPUESTA PREESTABLECIDO QUE HAY ALMACENADO EN UNA MEMORIA NO VOLATIL. LAS DIFERENCIAS ENTRE EL TIEMPO DE VERIFICACION Y EL TIEMPO PREESTABLECIDO INDICAN BIEN UNA FALLA DEBIDO A LA CIRCUITERIA TAL COMO UN MAL FUNCIONAMIENTO O UNA FUNCION REDUCIDA DE LOS COMPONENTES DEL SISTEMA DETECTOR O BIEN FALLAS PASAJERAS TAL COMO UNA PERDIDA DE LA CALIBRACION. ESTE TIPO DE AUTOVERIFICACION DE DIAGNOSTICO NO SOLO VERIFICALA CONTINUIDAD ELECTRICA DEL SISTEMA DETECTOR DE IMPACTOS SINO TAMBIEN LA INTEGRIDAD MECANICA Y LA CALIBRACION DEL SISTEMA DETECTOR.
