Abstract

L'invention concerne un procédé et un système d'ajustement de la plage de couverture réseau d'un nœud d'accès à l'Internet des objets. Le procédé comprend les étapes suivantes : un nœud d'accès à l'Internet des objets reçoit une instruction de détection de signal envoyée par une unité de convergence; le nœud d'accès à l'Internet des objets détecte des dispositifs terminaux connectés à l'accès à l'Internet des objets à l'intérieur d'une zone désignée comme étant des dispositifs terminaux cible; le nœud d'accès à l'Internet des objets acquiert la RSSI des dispositifs terminaux cible; le nœud d'accès à l'Internet des objets conditionne le nombre de dispositifs terminaux cible et la RSSI de chaque dispositif terminal cible dans un paquet de données qu'il envoie à l'unité de convergence; sur la base du paquet de données, l'unité de convergence ajuste le poids de faisceau de l'antenne du nœud d'accès à l'Internet des objets et envoie le poids de faisceau au nœud d'accès à l'Internet des objets; et, sur la base du poids de faisceau, le nœud d'accès à l'Internet des objets ajuste l'intensité de transmission de signal de l'antenne correspondante. La présente invention est utilisée pour ajuster de manière flexible la portée de couverture réseau sans fil du nœud d'accès à l'Internet des objets afin de mettre en œuvre une surveillance et une gestion intelligentes de l'Internet des objets.
