摘　　要：以MSP430超低功耗单片机为核心,针对现有计时设备使用传统电池、具有累积误差等缺点,设计了一种太阳能低频时码接收装置。使用太阳能电池为系统供电,采用超级电容器作为储能介质。同时,加入了低功耗低频时码接收模块,并设计了一套解码算法用于校正系统时间。系统能自动校正系统时间至标准北京时间且不存在累计误差,对太阳能电池的最大功率点进行跟踪以达到最高转换效率,并可保证在阴雨天气等弱光环境中连续工作。This paper approaches a design of solar-powered radio-controlled clock based on the MSP430 ultra-low power microcontroller.It uses solar panel and super capacitor as its power source and storage.And a RX model was involved in the clock for receiving low-frequency time-code signal.A simple algorithm of decoding is in charge of decoding time-code and setting the clock to the correct time.The system time could automatically set the time to Beijing standard time with no accumulative error.It could track the max power point of the solar panel to ensure the highest harvesting efficiency.In low-light situation such as rainy day the clock could still perform well.
