英语翻译摘 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

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。Key words:MCU data acquisition temperature control
