Abstract

L'invention concerne un système d'antennes, un procédé de commande, un processeur, un système de prises de vues et un support de stockage. Le système d'antennes comprend une pluralité d'antennes directionnelles à orientations variables. Une ou plusieurs antennes directionnelles sont sélectionnées par utilisation d'un processeur, selon l'intensité de signaux des antennes directionnelles, parmi la pluralité d'antennes directionnelles en tant qu'antenne de réception, laquelle reçoit un signal de données de service d'une source de signaux, de manière à éviter les problèmes de dépenses inutiles et de faible précision dus à un réglage manuel de la direction, de l'angle et de paramètres analogues d'un système d'antennes ; et par réglage de la direction, de l'angle et de paramètres analogues dudit système à l'aide d'un moteur, ce qui permet de mettre en œuvre les effets techniques d'économie de coûts de moteur et d'amélioration de la précision. De plus, sélectionner une antenne de réception selon l'intensité de signaux équivaut à la sélectionner par combinaison des performances de transmission de signaux entre un système d'antennes et une source de signaux et l'effet technique d'amélioration des performances et de l'efficacité de transmission est donc mis en œuvre.
