Abstract

La présente invention concerne un système de surveillance de dispositifs de protection de signal, un procédé pour système de surveillance de dispositifs de protection de signal, et un dispositif et un support de stockage lisible. Un dispositif de protection de signal est disposé dans une première zone, et un concentrateur est disposé dans une seconde zone. La seconde zone se trouve à l'extérieur de la première zone, la première zone est une zone de rayonnement de protection de signal du dispositif de protection de signal, et le concentrateur ne se trouve pas dans la zone de rayonnement de protection de signal. Par conséquent, le concentrateur peut réaliser normalement une communication. Lorsque le dispositif de protection de signal fonctionne, des informations de protection de signal sont transmises au concentrateur au moyen d'un signal sans fil cible, qui présente une bande de fréquences différente de celle d'un signal à protéger. Par conséquent, le dispositif de protection de signal peut transmettre les informations de protection de signal à un serveur de surveillance de protection au moyen du concentrateur.
