基于STC单片机的多功能电子钟的设计

Design of multi-function electronic clock based on STCsingle chip microcomputerAbstract With the development of society and the progress of human science andtechnology,people recognize time by observing the sun's rotation,hourglass,pendulum clock to electronic clock.The advent of electronic clocks has made it easierfor people to know time in the course of their development.Compared with thetraditional mechanical clock,it has the advantages of accurate walking time,visualdisplay,no mechanical transmission device,etc.,and is widely used in People's Dailylife.In life.However,some common electronic clocks on the market have a singlefunction,without time calibration,alarm clock,solar calendar,solar calendar andother functions.These functions cannot meet the needs of our life and work undercertain conditions.Therefore,it has become an urgent problem to develop amultifunctional clock that meets the above requirements and has high costperformance.This paper aims at the shortcomings of some common electronic clocksin the market,such as single function,insufficient time calibration,solar calendar andsolar term display.A multifunctional electronic clock based on STC microcontroller isdesigned and developed.The hardware circuit and software design of the system areintroduced.It can not only realize the year,month,day,week,time,minutes,secondsof the basic information,but also can display the solar calendar,solar terms,lunarcalendar information.Birthday setting,time calibration,alarm clock setting and otherfunctions.The test of the physical device shows that the clock has the advantages ofhigh precision,multiple functions,stable operation and simple circuit.Key words:STC single chip microcomputer;Multi-function electronic clock;The timecalibration
