学校电子日历的研发

摘要

提出了一种针对学校的专用电子日历,除基本的时间显示功能外,还有温度显示和倒计时提醒功能.系统以AT89S51单片机和DS12C887实时时钟日历芯片作为核心,利用DS18B20数字温度传感器测量环境温度.系统电路简单,性能可靠,操作简单,实时性好,时间和温度精度高.该电子日历可应用于一般学校的办公室和教室中,给教师和学生带来更多的方便.%A special electronic calendar for school was presented in this paper.The electronic calendar not only has the basic time display function,and also have temperature display and countdown remind functions.In this system,Microcontroller (AT89S51) and real-time clock calendar chip (DS12C887) are the two cores,the digital temperature sensor (DS 18B20) is used to measurement environment temperature.The system is a simple circuit,reliable performance and simple operation.The time and temperature are measured accurately.This electronic calendar can be applied to general school office and the classroom,more convenients will be brought to the teachers and students.
