Abstract

L'invention concerne un procédé de contrôle automatique de lignes d'alimentation électriques aériennes (LA), qui consiste à recueillir des informations sur l'état du conducteur de la LA, à traiter les informations obtenues et les transmettre à un opérateur vers un serveur distant; le recueil des informations sur l'état du conducteur de la LA se fait à l'aide d'au moins trois dispositifs de lecture qui vont chacun générer et envoyer un signal d'interrogation dans une plage de fréquence sur un canal radio, à l'aide d'un antenne émettrice-réceptrice, vers au moins un capteur de température électroacoustique passif sans fil et radiofréquence disposé sur le conducteur de la LA. Chaque dispositif de lecture comprend au moins un capteur de température où on génère un signal de réponse, et on effectue une modulation du signal, comprenant les informations sur sa température. Le signal d'interrogation réfléchi par le capteur de température électroacoustique passif revient vers le dispositif de lecture correspondant qui va effectuer un traitement des informations obtenues en convertissant les informations de modulation du signal retour en informations sur le changement de tempéarture du conducteur de la LA. La transmission des informations traitées se fait par un système d'armoire dans laquelle un contrôleur intégré collecte les informations de température depuis chacun des trois dispositifs de lecture et transmet les données sur un réseau sans fil à un opérature vers un service distant.
