摘　　要：针对海洋环境监测系统中供电电池组有限储能与仪器长期工作之间的矛盾,进行了自治式海洋环境监测系统的低功耗研究。从节能降耗、充分利用水体能源出发,将定点锚泊潜标和浮标技术相结合,采用双浮体技术,基于能量守恒,研制了一种储能型的传动装置;在分析了影响系统功耗的各种因素的基础上,对单片机数据采集控制存储系统进行了低功耗设计,为海洋环境监测系统长期在位作业提供了有力的能源保证,很好地解决了海洋环境监测系统的能源供应问题,使得该系统可以依靠单一的传感器组完成深达55 m以上的水体次表层海洋要素的长期连续垂直剖面观测。The work durability of a battery powered marine environment monitoring system is limited by the battery volume. Research on low-power consuming, autonomous ocean environment monitoring system had been carried out. To save energy and make full use of the water energy, this profiler adopted the technique of two-float assem- blies by incorporating a small, instrumented profiling buoy with a fixed-point mooring main submersible buoy. An energy-conserving transmission had been developed under the energy conservation principle. Based on the analysis of the factors affecting power consumption, low-power design of the microcontroller data acquisition and control system had been completed. These designs could satisfy the abundant energy need for the long-term inplace operation of the ocean environment monitoring system. The prominent advantage of the system is not limited by the battery capacity and can provide 55 meters ocean elements continuous profiles relying on a single sensor group.
