Abstract: With the design goal of achieving low-power consumption, multi-parameter measurement, safety and reliability, a design of marine multi-element observation system is proposed based on Beidou satellite communication. Designed with embedded microcontroller STM32F103RET6 as its core, it realizes marine environmental noise measurement with drifting buoy as the carrier, and achieves multi-element observation of ocean temperature, air pressure, wind speed, wind direction and surface sea temperature. Power supply is composed of rechargeable lithium battery packs and solar energy panels. The necessary power management is carried out at the same time to effectively improve the working life of the drifting buoy. The Beidou system with independent intellectual property rights in China is used for positioning and two-way communication, witch is of a higher safety level. Experiment results show that the marine multi-element observation system based on Beidou communication is feasible, meeting the requirements of low-power consumption, multi-parameter measurement,safe and reliable design. The design provides a new hardware design method for marine multi-parameter data acquisition control with surface drifting buoy as the carrier.
