Le compteur d'indice de v\u00e9g\u00e9tation enti\u00e8rement automatique XST-VINet produit par Beijing StarView Technology Co., Ltd. se compose de plusieurs sous-n\u0153uds et n\u0153uds de convergence avec 6 canaux d'absorption spectrale sur les c\u00f4t\u00e9s sup\u00e9rieur et inf\u00e9rieur, et c'est un instrument de surveillance de l'indice de v\u00e9g\u00e9tation en r\u00e9seau bas\u00e9 sur l'architecture de l'Internet des objets (IoT). Il est capable d'effectuer une surveillance automatique par r\u00e9seau sans fil multi-n\u0153uds, d'obtenir de longues s\u00e9ries temporelles de l'indice de v\u00e9g\u00e9tation et de t\u00e9l\u00e9charger les donn\u00e9es agr\u00e9g\u00e9es vers le serveur.<\/p><\/p>\n\n\n\n

Bas\u00e9 sur des algorithmes d\u00e9velopp\u00e9s par ses soins, il enregistre des donn\u00e9es brutes et calcule automatiquement plusieurs indices de v\u00e9g\u00e9tation :<\/p><\/p>\n\n\n\n
