| With the design goal of low power consumption, multi-parameter measurement, safety and reliability, a design of marine multi-element observation system based on Beidou satellite communication is proposed. Designed with embedded microcontroller STM32F103RET6 as the core, it realizes marine environmental noise measurement with drifting buoy as carrier, and realizes multi-element observation of ocean temperature, air pressure, wind speed, wind direction and surface sea temperature. Power supply is composed with rechargeable lithium battery pack and solar energy. And 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 higher safety. Experiments 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 carrier. |
