摘 要
铃声作为学校必不可少的基础设施，起到提醒老师和学生的进行正常工作和学习的作用。然而，传统的铃声设备已经满足不了智能校园的需求，为了解决此类问题，设计一款智能铃声控制系统势在必行。本系统采用STC89C52单片机主控芯片，通过DS1302同步上下课时间；通过按键设置并修正上下课时间，共设置8个时间段，表示8节课，通过LCD1602显示屏对上下课时间进行显示，通过音乐播放电路模块进行上下课铃声播报。通过实物进行测试，此次设计的学校智能铃声系统，可以按照预定的上下课时间进行音乐播报提醒上下课，有效解决学校铃声播报不准时等现象发生，并维护了学校的正常生活和学习次序，促进教育行业的持续发展，为我国科学社会的发展奠定良好基础。

Abstract
As an essential school infrastructure, the bell serves as a reminder to teachers and students to carry out normal work and study. However, the traditional ringtone equipment has been unable to meet the needs of the intelligent campus, in order to solve such problems, it is imperative to design an intelligent ringtone control system. The system uses STC89C52 microcontroller chip, through DS1302 synchronous class time; Set and correct the start-and-end time by pressing the button, and set 8 time periods, indicating 8 classes. Display the start-and-end time through the LCD1602 display screen, and broadcast the start-and-end bell through the music playing circuit module. Through the kind of test, the design of the school intelligent ringtone system, can be in accordance with the scheduled time of the school bell broadcast music to remind up and down the class, effectively solve the school ringtone broadcast is not on time phenomenon, and maintain the normal school life and learning order, promote the sustainable development of education industry, laying a good foundation for the development of our science society.
