本文设计了一款基于单片机的实时时钟同步系统.该系统各个普通的时钟模块通过无线数据传输接收以提取G PS时间信息为时钟源的精准时钟模块的广播报时,可自动修改自身时间常数,以适应晶振频率的变化,最终能达到与时钟源同步.本文对该设计的基本原理和关键技术作出了一定的阐述,并给出了可行的软、硬件设计方法.

T his paper has designed a real-tim e clock synchronization system based on single chip m icrocom-puter.Each ordinary clock m odule ofthe system through w ireless data transm ission and receiving,the G PS tim e inform ation is extracted to broadcast the tim e clock source precision clock m odule. C om pared w ith their ow n tim e, the ordinary clock m odule autom atically m odify its tim e constant, in order to adapt to changes in the crystal fre-quency and eventually to achieve synchronization w ith the clock source. In this paper, the basic principle and key technology of the design has been expounded,and a feasible m ethod of softw are and hardw are design is presented.
