In view of the saturation tendency of ships in the Yangtze Estuary deepwater channel,we carry out a preliminary study on the construction of the Yangtze Estuary intelligent waterway.Adopting IOT monitoring and safety early-warning technologies,and adding some sensor facilities,space-time information data system and information cloud platform based on existing conditions,we construct the Yangtze Estuary intelligent waterway,which is of great significance for the improvement of the traffic efficiency and capacity of the Yangtze Estuary deep-water channel.
