Abstract

La présente invention se rapporte au domaine technique de l'Internet des objets. Dans ses modes de réalisation elle concerne un procédé et un système de détection d'une intensité de signal dans un Internet des objets. Le procédé comprend les étapes suivantes : un nœud d'accès reçoit des informations d'indication de signalisation de signal émises par une unité de convergence, détecte des dispositifs terminaux connectés au nœud d'accès dans une zone spécifiée pour servir de dispositifs terminaux cible, obtient périodiquement des valeurs d'indication d'intensité de signal reçu (RSSI) des dispositifs terminaux cible, obtient une valeur RSSI moyenne de la zone spécifiée sur la base des valeurs RSSI, et conditionne le nombre de dispositifs terminaux cible et la valeur RSSI moyenne dans un paquet de données qu'il envoie à l'unité de convergence lorsque la valeur RSSI moyenne est inférieure à un seuil de signal des informations d'indication de signalisation de signal ; l'unité de convergence ajuste un poids de faisceau d'une antenne du nœud d'accès d'après le paquet de données, et envoie le poids de faisceau au nœud d'accès ; et le nœud d'accès ajuste l'intensité de transmission de signal de l'antenne d'après le poids du faisceau d'ondes. La présente invention est utilisée pour ajuster périodiquement une intensité de signal de sorte à garantir la stabilité de signal d'un Internet des objets ainsi que la fiabilité de transmission de données.
