Abstract

UN SISTEMA DE DETECCION DE INTRUSION MULTISENSOR, QUE TIENE INMUNIDAD CONSIDERABLEMENTE PERFECCIONADA A FALSAS ALARMAS, EMPLEA UN PRIMER SENSOR (66) PARA DETECTAR UNA INTRUSION EN UN VOLUMEN DE ESPACIO, MEDIANTE UN PRIMER FENOMENO FISICO, Y UN SEGUNDO SENSOR (500) PARA DETECTAR UNA INTRUSION EN EL VOLUMEN DE ESPACIO MEDIANTE UN SEGUNDO FENOMENO FISICO DIFERENTE DEL PRIMER FENOMENO FISICO. EL PRIMER SENSOR (66) GENERA UNA PRIMERA SEÑAL EN RESPUESTA A LA DETECCION DE UNA INTRUSION DENTRO DEL VOLUMEN DE ESPACIO, Y EL SEGUNDO SENSOR GENERA UNA SEGUNDA SEÑAL EN RESPUESTA A UNA DETECCION DE UNA INTRUSION. UN MICROCONTROLADOR (12) GENERA UNA SEÑAL DE ALARMA AL PRODUCIRSE UNA PRIMERA SEÑAL Y UNA SEGUNDA SEÑAL DENTRO DE UN PRIMER INTERVALO, LA PRESENCIA DE OTRA PRIMERA SEÑAL Y UNA SEGUNDA SEÑAL DENTRO DE UN POSTERIOR SEGUNDO INTERVALO, Y LA PRESENCIA DE OTRA SEGUNDA SEÑAL DENTRO DE UN TERCER INTERVALO POSTERIOR, EL MICROCONTROLADOR (12) ESPERA (A) EN ESTADO 0 HASTA QUE SE PRODUCEN UNA PRIMERA SEÑALY UNA SEGUNDA SEÑAL DENTRO DEL PRIMER INTERVALO, DESPUES DE LO CUAL CAMBIA SU ESTADO (B) A ESTADO 1, DESDE EL CUAL RETORNA (C) A ESTADO 0, SALVO QUE SE PRODUZCA OTRA PRIMERA SEÑAL DENTRO DEL POSTERIOR SEGUNDO INTERVALO, CON LO QUE CAMBIA DE NUEVO (D) A ESTADO 2, DESDE EL CUAL RETORNA (E) A ESTADO 0, SALVO QUE SE PRODUZCA OTRA SEGUNDA SEÑAL DENTRO DEL TERCER INTERVALO POSTERIOR, DESPUES DE LO CUAL CAMBIA AL ESTADO DE ALARMA. RETORNA (G) AL ESTADO 0 DESDE EL ESTADO DE ALARMA DESPUES DE UN CUARTO INTERVALO PREDETERMINADO.
