基于C51单片机的多功能电子钟系统设计与仿真

Design and Simulation of Multifunctional Electronic Clock Based on C51 Microcontroller

以AT89C51单片机为核心,配合七段数码管显示模块、DS1302时钟模块、DS18B20数字温度传感器模块、蜂鸣器报时模块以及按键模块,设计具有显时、调时、测温、报时功能于一体的多功能电子钟。最后,利用Keil C51和Proteus软件进行C51编程与系统仿真,得到了预期效果。这种多功能电子钟由于成本低廉、操作简单,可以被大量推广到市场中。

This paper takes AT89 C51 Single Chip Microcomputer as the core and uses the seven-segment digital tube display module, the DS1302 clock module, the DS18 B20 digital temperature sensor module, the buzzer timing module and the key-press module to design a multifunctional electronic clock which can display time, adjust time, measure temperature and report time. Keil C51 and Proteus software is used to do C51 programming and system simulation and to get the desired effect finally. This kind of multifunctional electronic clock is extensively applied in the market because of its low cost and easy operation.
