基于单片机的自动打铃控制器摘要单片机正不断成为科技社会应用中的新浪潮，正是单片机的加入，推动了自动化行业的发展，给生活带来极大的便利。然而单片机仅仅是微控制器，只有结合系统的硬件电路与软件算法控制才能完成目标的任务。简易自动打铃系统主要为学校服务，旨在减轻学校工作量、提高学校工作效率，避免因打铃不及时产生的大量不守时情况。本课题基于单片机 STC89C52 芯片搭建的自动打铃系统，简单方便，操作简单，易于实现。自动打铃系统应用广泛，在工业自动化中有广泛应该用，能够实时监控并精准定时报警，该设计加入了时钟显示，便于观察，更加人性化，更满足生产需要。经过调试，本课题实时性、可操作性都已达到了要求。关键词：单片机 自动打铃 时钟显示Single Chip Microcomputer Automatic Ring SystemAbstractMCU is becoming a new wave in the application of science and technology society. It is the joining of MCU that promotes the development of automation industry and brings great convenience to life.However, MCU is only a microcontroller, only the combination of the system's hardware circuit and software algorithm control to complete the target task.The simple automatic bell ringing system mainly serves for the school, aiming to reduce the school workload, improve the school work efficiency, and avoid the large amount of unpunctuality caused by the late bell ringing.This subject is based on the microcontroller STC89C52 chip set up automatic ringing system, simple and convenient, simple operation, easy to achieve.Automatic bell ringing system is widely used, which should be widely used in industrial automation. It can be used for real-time monitoring and accurate timing alarm. The design adds clock display, which is convenient for observation, more humanized and more satisfying for production needs.After debugging, the project has reached the real-time, operable requirements.Key Words：single chip microcomputer; Automatic ringing ...
