本科毕业设计基于单片机的作息时间控制器
基于单片机的作息时间控制器
摘要
单片机应用技术飞速发展，纵观我们现在生活的各个领域，而STC89C52RC 单片机在其中表现得很出色。本系统是由STC89C52RC单片机为控制核心，辅以必要的外围电路，设计了一个结构简单，功能齐全的作息时间控制器，采用DS1302时钟芯片来对计算时间，显示采用LCD1602液晶模块进行数字显示，设计出了更准确定时、更省电的控制系统。它具有设置时间、日期、星期的基本功能，并且能够显示年、月、日、时、分、秒、星期。能够设置多个闹钟时间，并能检测温度。系统选用单片机最小系统应用程序,添加比较程序、时间调整程序及蜂鸣程序，通过时间比较程序触发蜂鸣，实现闹钟功能，完成设计所需求的软件环境。测试程序的可行性并用Proteus进行仿真。
系统读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点，具有广阔的市场前景。

(College of Engineering, South China Agricultural University, Guangzhou 510642, China) Abstract: The rapid development of microcomputer application technology, in all areas of life we are now, and STC89C52RC single chip microcomputer in which did very well. This system is composed of STC89C52RC single chip microcomputer as control core, with the necessary peripheral circuits, design a simple structure, time controller with complete functions, using the clock chip DS1302 to calculate time, shows the use of LCD1602 liquid crystal module for digital display, design a more accurate timing control system, the more energy. It has set the time, date, week basic functions, and can display year, month, day, time, minutes and seconds, week. To set a number of alarm clocks, and can detect temperature. The system choose the smallest SCM system applications, add comparison program, time to adjust the procedure and buzzer procedures, through the time comparison procedures triggered buzzer, alarm clock function, completed the design needs of the software environment. Feasibility test program with the Proteus simulation.
The system is easy to read, intuitive display, functional diversity, simple circuit, low cost and many other advantages, has broad market prospects.
