Abstract

CETTE INVENTION CONCERNE UN PROCEDE ET UN SYSTEME DE SECURITE PAR DETECTION DE LA VARIATION D'UNE CONDITION D'UN ENSEMBLE COMPRENANT UN FIL CONDUCTEUR. ON MESURE UNE CARACTERISTIQUE ELECTRIQUE DE CE FIL CONDUCTEUR, ON LA COMPARE A UNE VALEUR ETALON, ON DETECTE UN DESEQUILIBRE EVENTUEL ENTRE LA VALEUR MESUREE ET LA VALEUR ETALON, ET ON EXPLOITE LA GRANDEUR RESULTANT DE CE DESEQUILIBRE POUR DECLENCHER UNE ALARME OU UNE INTERVENTION. ON PEUT PREVOIR UNE COMPENSATION DES VARIATIONS CLIMATIQUES AUXQUELLES LE FIL CONDUCTEUR EST SOUMIS. UN TEL SYSTEME EST UTILISABLE NOTAMMENT POUR DETECTER LES TENTATIVES D'EFFRACTION SUR UNE CLOTURE, LE VOL DE VEHICULES, UN DEBUT D'INCENDIE OU POUR DE NOMBREUSES AUTRES APPLICATIONS.
