摘　　要：介绍了一种单片机控制的能实现高同步的电波时钟的设计。该系统以16位单片机MSP430G2553为控制核心,采用LCD5110作为显示模块,自制天线分立元件搭建时钟信号接收、选频、滤波、放大、检波,AGC及比较电路提取电波授时信号,实现了自动授时、手动授时、AGC增益自动调节、秒表、倒计时与语音提示等功能,可根据按键设置及光照情况进入睡眠,支持键唤醒以及光唤醒,并显示信号强度,外加了语音提示功能。In this paper,the design of a radio controlled clock was presented.The clock controlled by a single chip microcomputer can achieve high synchronization. 16 bit single chip microcomputer MSP430G2553 was used as the control core in the system.LCD5110 was utilized as a display module. The system was powered by TPS61040 chip with solar panel.The self -made antenna discrete compo-nents were set up for clock signal reception,frequency selection,filtering,amplification,detection, AGC and compare circuit extraction radio timing signals.The automatic timing,manual timing,AGC au-tomatic gain adjustment,stopwatch,countdown and voice prompt functions were realized.The clock can enter sleep according to key settings and lighting conditions,also support the key wake -up and light wake,and show the signal intensity,plus the voice prompts.
