Abstract

La présente invention se rapporte à un système de collecte de données (1). Dans le système selon l'invention, une pluralité de nœuds (2) sont connectés en cascade dans un réseau à plusieurs bonds d'une structure en arborescence. Les nœuds (2) exécutent des opérations de transmission de données en tant que des nœuds de niveau inférieur, et ils exécutent des opérations de réception de données en tant que des nœuds de niveau supérieur, alternativement, sur une base de division dans le temps. Quand il fonctionne en tant qu'un nœud de niveau supérieur, un nœud (2) exécute une opération d'interrogation dans le but de recevoir des données en provenance de nœuds (2) qui se trouvent un niveau en dessous. Quand il fonctionne en tant qu'un nœud de niveau inférieur, un nœud (2) transmet des données de signalisation de fin de transmission qui indiquent la fin de la transmission des données collectées par le nœud (2) en question (le nœud lui-même). Quand des données de signalisation de fin de transmission ont été collectées à partir de tous les nœuds (2) qui se trouvent un niveau en dessous du nœud (2) en question, et que la transmission des données collectées par le nœud (2) en question est terminée, les données de signalisation de fin de transmission du nœud (2) en question sont transmises. De cette manière, des données peuvent être collectées avec une grande efficacité à partir de l'ensemble des nœuds. En outre, le nombre de trames d'interrogation inutiles peut être réduit.
