摘 要
单片机自20世纪70年代问世以来，以其极高的性能价格比，受到人们的重视和关注，应用很广、发展很快。单片机体积小、重量轻、抗干扰能力强、环境要求不高、价格低廉、可靠性高、灵活性好、开发较为容易。由于具有上述优点，在我国，单片机已广泛地应用在工业自动化控制、自动检测、智能仪器仪表、家用电器、电力电子、机电一体化设备等各个方面，而51单片机是各单片机中最为典型和最有代表性的一种。这次毕业设计通过对它的学习、应用，以AT89S51芯片为核心，辅以必要的电路，设计了一个简易的电子时钟，它由4.5V直流电源供电，通过数码管能够准确显示时间，调整时间，从而到达学习、设计、开发软、硬件的能力。
Design of the singlechip electronics clock
Abstract
Single slice machine from published in 70's for 20 centuries, is compare with its very high function price, is value by people and pay attention to, apply very widely, develop very quickly. Single slice the machine physical volume is small,the weight is light,the anti- interference ability is strong,the environment haven't high request,the price is cheap,the credibility is high,vivid good,develop more easy. In order to having an above-mentioned advantage, at the our country, single slice the machine is broadly applied already to turn an equipment at industrial automation control,automatic examination,intelligence instrument appearance,home appliances,electric power electronics,the machine electricity integral whole etc. each aspect, but 51 machines is is a typical model most and have a representative most in each machine of a kind. This graduation design passes to its study and application, Take the AT89S51 chips as core, assist with the electric circuit of the necessity, design a simple electronics clock, it from the 4.5 V direct current power supply power supply, pass the figures tube can accurate manifestation time, adjust time。Arrive a study and design, develop thus soft,the ability of the hardware .
