I摘要摘要随着时间的推移，事物的发展越来越趋向于高科技，单片机的出现，受到了社会各界的广泛关注，这是由于单片机具备丰富的功能。单片机的特点为：尺寸小，价格低，抗干扰强，开发容易等。运用的范围也很广，如检测，仪表，电子，机电等设备的各方面都有不可或缺的作用。多功能电子钟是我们最常见的计时工具之一，用 STC89C52 单片机研究的多功能电子钟系统，加上必要电路，构成了一个能调整误差的多功能数字电子钟。本文论述了其工作原理，对各个功能模块进行了详细的分析和研究，此外还对系统的工作流程以及具备的各项功能进行详细的介绍，从而判断设计方案正确与否。使用 C 语言对系统的软件部分进行编程,再用 keil 进行调试分析，通过 PROTEL99SE 进行电路模拟，可以让单片机显示年、月、日、时、分、秒、周并具有校准功能和和闹钟提醒功能，除此之外还具有测量环境的温湿度功能。关键词 : 电子钟；STC89C52； 单片机IIAbstractAbstractWith the passage of time, the development of things tends to be more and more high-tech. The emergence of single-chip computers has attracted widespread attention from all walks of life, which is due to the rich functions of single-chip computers. The characteristics of MCU are: small size, low price, strong anti-interference, easy development and so on. The scope of application is also wide, such as detection, instrumentation, electronics, mechanical and electrical equipment in all aspects have an indispensable role. Multifunctional electronic clock is one of the most common timing tools. The multi-functional electronic clock system studied by STC89C52 microcontroller and the necessary circuit constitute a multi-functional digital clock that can adjust errors. In this paper, the working principle of the system is discussed, and the function modules are analyzed and studied in detail. In addition, the working flow and functions of the system are introduced in detail, so as to judge whether the design scheme is correct or not. ...
