摘　　要：文章简述了系统各模块方案的论证与选择的相关内容。文中在对本系统的各个模块的方案进行论证与实际应用相比较的基础上,最终方案选用AT89C52作为主控制系统来控制时钟的准时运转,采用独立式按键控制本设计系统将要实现的全部功能,选用LCD液晶动态扫描来显示时间。并对系统的硬件设计与实现进行分析,同时,对系统的软件设计进行分析。This article briefly describes the related content about the choice and the demonstration of system＇s each module scheme. On the basis of comparing these demonstrations with practical application, AT89C52 is finally chosen as the main control system to control the punctual operation of the clock, and independent buttons are adopted to control all functions that the system will realize. Moreover, LCD dynamic scanning is chosen to display time. And the article analyzes the design and implementation of the hardware design, as well as the software design of the system.
