Design and Experimental Study of Monitoring Buoys for Rapid Flow Unmanned Areas

Monitoring buoys are one of the important means to obtain environmental parameters of marine water resources. However, in some rapids, shallow waters, rocky areas, and areas where personnel cannot reach, existing buoys cannot meet the requirements for water environment monitoring. Resulting in a lack of water environment information in the aforementioned unmanned areas. Based on the characteristics of unmanned areas, this article lists the key technologies of water environment monitoring buoys in unmanned areas. From a practical perspective, a water environment monitoring buoy that can be used in rapids and shallow water unmanned areas has been designed. Field simulation environmental tests have been conducted in rapids, shallow water, rocky, and canyon river sections. The test results show that the buoy structure strength meets the design requirements, and the buoy can transmit coordinates and other information in real-time under weak satellite signals.
