Abstract
L'invention concerne un système d'émission sans fil comprenant une antenne d'émetteur, un capteur, un circuit de démodulation et un dispositif de commande d'émetteur. Le capteur est conçu pour détecter des informations électriques associées à des signaux sans fil CA, les informations électriques comprenant, au moins, une tension des signaux sans fil CA. Le circuit de démodulation est conçu pour recevoir les informations électriques provenant de l'au moins un capteur, détecter un changement dans les informations électriques, déterminer si le changement dans les informations électriques satisfait ou dépasse un seuil d'élévation ou un seuil de chute, si le changement dépasse l'un du seuil d'élévation ou du seuil de chute, générer une alerte et délivrer une pluralité d'alertes de données. Le dispositif de commande d'émetteur est conçu pour recevoir la pluralité d'alertes de données provenant du circuit de démodulation et décoder la pluralité d'alertes de données en signaux de données sans fil.
