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
