摘 要
目前家用的数字电子钟,多数只能显示小时、分钟等信息,功能单一,而且大都采用LED数码管作为显示器件,功耗大,不能令消费者满意.为此,本文设计了一款多功能数字式电子钟,它以AT89S52单片机为控制核心,通过实时时钟芯片DS1307和数字温度传感器DS18B20构成了一个多功能的数字时钟系统.通过按钮,向单片机输入信息,用来调节时间.再由单片机向实时时钟芯片传输数据.时钟芯片将数据再传送给单片机处理后,由显示器输出.温度传感器将采集的信息传给单片机处理后,由显示器输出温度数值.
软件程序均采用C语言编写,便于移植与升级.它可以显示年、月、日、小时、分钟等时间信息,同时可以显示环境的温度信息.还具有按键调时、设定闹铃等功能,而且通过一块3.18V的备用电池,在单片机断电后让时钟芯片DS1307独立工作,因此每次给单片机上电即可显示当前时间,无需调整.时钟采用液晶LCD128*64作为显示器,界面友好,功耗低.
关键词：单片机 数据采集 温度控制

Abstract
At present the number of household electronic bell,the majority can only display hours,minutes and other information,features a single,and mostly used as the LED digital display,power consumption,so that consumers can not be satisfied.To this end,we designed a multi-functional digital electronic clock,it has AT89S52 SCM for the control of the core,through real-time clock chip DS1307 and digital temperature sensor DS18B20 form a multi-function digital clock system.Through the button,enter information to the microcontroller,is used to adjust the time.By the real-time clock chip microcontroller to transmit data.Clock chip MCU will be given to processing data longer,by the display output.Temperature sensors will collect the information to the SCM processed,the temperature output value by the display.
Software programs are written using C,for transplantation and upgrades.It can show year,month,day,hours,minutes,hours and other information,and can display the temperature information.Also a key tune,set an alarm function,but also through a 3.18 V backup battery power in the microcontroller chip DS1307 after the clock to work independently,each to the MCU power to display the current time,Without adjustment.Clock used as a liquid crystal display LCD128 * 64,user-friendly,low power consumption.
