摘　　要：漂流浮标具有结构简单、易布放、不需要额外动力等方面的优点,在海洋观测领域已经有了较为广泛的应用。然而现有的漂流浮标为了控制成本和整体功耗,搭载的传感器较少,在使用中能够采集到的数据种类较少,并且由于电子系统设计相对简单,一旦出现故障,无法解决,导致实际使用时长往往达不到设计使用时长。因此,本文以低功耗、高可靠性、多样化载荷为设计目标,提出一种具备扩展性的双系统漂流浮标的设计方案,能够尽可能地提高漂流浮标的可靠性,同时基于双系统设计了一种低功耗切换算法。该款漂流浮标系统可在主模块损坏时及时启用备用模块工作,并可对当前电池电量、工作环境状态及模块功能状况进行处理分析,根据分析结果实现对系统未来工作模式的决策,系统功耗降低了20%,同时实现了漂流浮标系统的长时序高效观测。The drifting buoy has the advantages of simple structure,easy distribution,no need for extra power,etc.,and has been widely used in the field of ocean observation.However,in order to control costs and overall power consumption,the existing drifting buoys are equipped with fewer sensors,resulting in less types of data that can be collected in use,and because the design of the electronic system is relatively simple,once the fault occurs,it cannot be solved,resulting in the actual use time often does not reach the design use time.Therefore,with the design goal of low power consumption,high reliability and diversified load,this paper proposes a design scheme of dualsystem drifting buoy with scalability,which can improve the reliability of drifting buoy as much as possible.Meanwhile,a low-power switching algorithm is designed based on the dual-system.The drifting buoy system can enable the standby module to work in time when the main module is damaged,and can process and analyze the current battery power,working environment status and module function status,and realize the decision of the future working mode of the system according to the analysis results,reducing the power consumption of the system by 20%,and realizing the long-term efficient observation of the drifting buoy system.
