基于MSP430超低功耗海洋漂流浮标采集器的设计

摘要

为了满足远海气象水文监测需要,设计一种基于MSP430MCU海洋气象水文漂流浮标采集器;重点研究采集器电路设计及程序设计.为了最大限度提高采集器运行时长,采用超低功耗微处理器,供电系统采用锂电池与太阳能电池板,充电控制采用最大功率点跟踪(MPPT),并为所有部件设置独立电源控制;采集器运用国内自主研发的北斗通信方式,实现深远海气象水文数据采集.实际测试结果验证了系统的合理性和实用性,对于深远海洋气象水文观测意义重大.%In order to meet the requirements of meteorology and hydrology monitoring of high sea,an ocean meteorology and hydrology drifting buoy collector based on MSP430MCU was designed. The circuit design and program design of the collec-tor are studied emphatically. In order to prolong the operation time of the collector to the maximum extent,the ultra-low power consumption microprocessor is adopted in the collector,the lithium battery and solar panel are used in its power supply system, the maximum power point tracking(MPPT)is used for charging control,and all components are set with the independent power supply control. The Beidou communication mode researched and developed independently by China is employed in the collector to acquire the meteorology and hydrology data of high sea. The practical test results verify that the system is rational and practi-cal,and has great significance in meteorology and hydrology observation of high sea.
