Underwater terrain monitoring and big data analysis under digital channel conditions

Since the quality of underwater topographic survey of waterway affects the safety production in many fields, researchers put forward an underwater topographic monitoring method based on wireless sensor network (WSN) on the basis of understanding the defects of traditional methods. Combined with practical case analysis shows that this method is used to design the wireless node of bathymetric survey, select a two-dimensional plane coordinates of the node localization algorithm analysis, and ultrasonic sensors are used to obtain the vertical depth coordinates, and then use 3 d coordinates of all the nodes to surface fitting, eventually to build underwater terrain. Finally, the experimental results show that this method is feasible and meets the operation requirements under the current digital channel conditions.
