Study on the Key Technology of Marine Environment Monitoring System Based on Underwater Three-dimensional Sensor Networks

The shortcoming and requirement of marine environment monitoring technology in China were summarized and a new system for marine environment monitoring based on underwater three-dimensional sensor networks was introduced.The constitution,system construction and key technologies were discussed and the automated lifting underwater sensor node was designed.The communication mode between underwater nodes,survey system and control center were discussed.At last,the application foreground of underwater three-dimensional sensor networks was prospected.
