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。

Abstract:

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 components 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,AGCautomatic gain adjustment,stop watch,countdown and voice prompt functionswere realized.The clock can enter sleep according to key settings and lighting conditions,also support the key wake up and light wake,and showthe signal intensity,plus the voice prompts.

Key words: single chip microcomputer, radio controlled intelligent clock, radio controlled timing, solar power supply
