Design of low power consumption marine environment monitoring system based on STM32F407

A mobile buoy-type low-power marine environment monitoring system is designed. The STM32F407 single-chip microcomputer is used as the control core of the ocean buoy, and the other two single-chip microcomputers are used to complete the data acquisition and forwarding between the various parts. Under the design requirements of rich and scalable interfaces, this embedded architecture greatly reduces power consumption. The buoy is innovatively divided into two parts: dry cabin and wet cabin in terms of mechanical structure. The corresponding entire observation system is divided into two main parts: the state perception system and the underwater detection system. Combined with the photovoltaic panel above the buoy, it controls the buoy. While the diameter is as low as 1.15 meters, the power generation efficiency is effectively guaranteed. The system has been optimized for low power consumption from the aspects of mechanical structure and software and hardware design. The system has achieved the expected goal through power consumption analysis and intersystem joint debugging test. It is a new system integration framework and is worthy of application and promotion.
