摘　　要：数字时钟是我们生活中必需的计时工具,传统的数字时钟主要结构为石英晶体,其结构特性导致时钟易出现误差且受环境温度影响大。本次设计以单片机替代石英晶体完成时钟的正常工作,其走时更准确,运行更稳定,且可以通过编程实现更多的功能。相比于传统的数字时钟,本设计具备独立的按键控制方式和更好的显示效果,且设计简单、成本低、性能可靠,可更加广泛的应用于多种日常计时场景。通过实验验证,证明了其可行性和相比于传统数字时钟的优势。Digital clock is a necessary timing tool in our life,the main structure of the traditional digital clock is quartz crystal,which makes the clock prone to errors and greatly affected by the ambient temperature.This design decided to replace quartz crystal with single chip microcomputer to complete the normal work of the clock,which has more accurate travel time,more stable operation,and can achieve more functions through programming.Compared with the traditional digital clock,this design has independent key control mode and better display effect,and the design is simple,low cost,reliable performance,can be more widely used in a variety of daily timing scenes.Through experimental verification,the design proposed in this paper is feasible and has more advantages than the traditional digital clock.
