基于STC12C5A60S2多功能数字电子钟的设计与创新1.docVIP

摘 要 20世纪末，电子技术获得了飞速的发展。在其推动下，现代电子产品几乎渗透到了社会的各个领域，并且产品的性能越来越高，更新的节奏越来越快。 与此同时，人们越来越重视时间观念，可以说是时间和金钱划上了等号。对于那些对时间把握非常严格和准确的人或事来说，时间的不准确会带来非常大的麻烦，所以对于时间的简单明了而且认读速度快、精准度高这些方面有了很多要求。因此，研究数字电子钟，有着非常现实的意义。 在智能化仪器仪表中，控制核心均为微处理器。单片机以其高性能、高速度、体积小、价格低廉、稳定可靠而得到广泛应用，而单片机结合简单的接口电路即可构成电子钟。 因此，本设计采用单片机技术实现多功能电子钟。特色是基于STC12C5A60S2作为核心，数码管显示时、分、秒，发光二极管做流水灯装饰，采用创新设计——逆向思维进行光控实现多功能数字电子钟。这种设计的优点是电路简单，显示直观，性能稳定，实时性好，时间精度高，性价比高，并且操作方便，可以在实际中广泛应用。此设计是顺延钟表的一个发展方向，具有一定的实用价值和研究意义。 关键字：电子钟，单片机，数码管，光控，多功能 Abstract In the 20th century, electronic technology has been developed rapidly. Modern electronic products are almost permeated each social fields in its driven, and the products performance is getting higher and higher, update speed becomes more and more quickly. At the same time, people pay more and more attention to the concept of time, as to say that time and money off equals. Someone or something grasps time very strict and accurate,time inaccurate will bring great trouble,so it has a lot of requirements of the simple and clear and the high precision accuracy about time.Therefore, to study digital electric clock has very realistic significance. Control core are microprocessors in the intelligent instrumentation, MCU is widely used by its high performance, high speed, small volume, low prices, stable and reliable,and MCU combined with the simple interface circuit can constitute electric clock. Therefore,this design use MCU-technology to achieve multi-function electronic clock.Kemel is based on STC12C5A60S2, Nixie tube show time, light-emitting diodes as water lamp, and using innovative design which is by reverse thinking to realize light-operated for Multi-function digital electric clock. Simple circuit,visual display, stable performance,good instantaneity,high precision, cost-effective,and easy operation all these advantages can be widely used in practice. This design is a development trend of postpone clocks and has certain practical value and significance of the research. Keywords:
