| 摘要: |
| 针对极区冰基拖曳式海洋剖面浮标长期稳定获取极区水文和气象数据的工作需求, 进行了浮标系统的低功耗方案设计。该方案基于超低功耗51系列微处理器, 根据最低功耗工作模式与最短工作时间原则, 采用高效的电源管理机制对浮标系统各个部分的能量消耗进行合理的分配与管理, 并应用了Argos卫星通讯模块ARGOS-3 PMT-RFM的BPSK调制低速数据传输模式, 可有效降低浮标系统的整体能耗。该浮标在北极冰站上长达1 年的运行情况表明该系统工作稳定, 所采用的低功耗能量管理方案实现了浮标系统长期连续观测的需求。该浮标的成功试验和推广应用有助于极地研究人员更准确地分析海冰变化过程。 |

| Abstract: |
| The polar drift-towing ocean profiler is required to work for a long time in order to obtain more hydro-meteorological information about the polar region. Therefore, to address this, a low-power scheme for the buoy system is designed in this paper. The application of efficient energy management with the 51 series micro control unit at its core contributes to reasonable power distribution which is in accordance with the principle of the minimum-power operation mode and the shortest possible working time. The Argos module (ARGOS-3 PMT-RFM) is used to provide low-speed data transmission by BPSK modulation. Consequently, the overall power consumption of the buoy system is reduced effectively. The operation of the buoy system for one year in the floating ice of the Arctic shows that the system has been working with stability, and that the low-power management scheme has fulfilled the requirements of long-term observation for the buoy system. The successful testing and application of the buoy is useful for polar researchers making more accurate analyses of the change processes of sea ice. |
