基于单片机的校园自动打铃器设计

Design of campus automatic bell ringer based on MCU

基于单片机的校园自动打铃器可以替代手动打铃,降低人工成本,非常适用于学校、企业等环境。电子产品的自动化是科学技术发展的趋势,通过单片机程序自动控制每个时间段的打铃,既可以保证打铃时间的准确性,又具有方便性和实用性。文章主要介绍一种基于AT89C52单片机的校园自动打铃器,通过AT24C02断电保存多个时间点,并根据设定好的时间点自动准确地响铃,具有一定的实用性。

Campus automatic bell ringer based on MCU can replace manual bell ringing and reduce labor cost, which is very conducive to schools, enterprises and other environments. The automation of electronic products is also the development trend of science and technology. The ringing of each time period can be automatically controlled by MCU program, which can ensure the accuracy of ringing time, and has convenience and practicability at the same time. This paper mainly introduces a campus automatic ringer based on AT89C52 MCU. The ringer can save multiple time points through AT24C02 power failure, and ring automatically and accurately according to the set time points, which has certain practicability.
