基于51单片机的八路抢答器设计(任务书,开题报告,外文翻译,论文13000字)
摘要
我们所生活的时代在不停的前进与发展,与时代的快速发展相对应,相应与电子有联系的技术也发展的十分迅速。在这些技术中,集成电路的发展是十分突出的,由于其技术的进步,加快了人们步入新时代的进度。日新月异的电子产品的更新换代,使人类的生活的更好。与计算机技术的提高相对应,电子也有对应的提高。计算机领域在不断的发展中取得了很多里程碑式的进步。在通信交流这个模块,取得了巨大的进步,使人们进入了高度一体化的社会。通过这次设计,可以将我们在学校中获得的知识运用到具体的任务中,通过将理论与现实联系,就可以将我们的能力提升到一个新的更高的水平。
抢答器在我们日常生活中的应用可以说非常广泛,在很多需要有竞争性的答题中,都需要使用抢答器来更加客观的进行判断来保证比赛的公平性。有多种方法可以实现我们所需要的功能,比如以电路为核心的模拟电路和数字电路相结合的方法。但这些方法的缺点较多,如生产过程复杂,在精度方面的可靠性低,占用了过大的面积,在实际中很难进行相应的安放和更新。基于上述的原因,我们不使用以电路作为核心的设计,而使用以单片机为核心设计的八路抢答器,用于控制逻辑和产生信号。在当今这个逐渐普及数字化用品的时代,由于单片机的类型逐渐丰富,可以实现的功能也越来越多,单片机的地位已经不可取代。单片机应用技术现在已经成为一种全新的应用在工程方面的技术。 [来源:http://www.doc163.com]

Abstract
Electronic closely related to our lives has also been rapid development. Especially with the development of large scale integrated circuits, we have entered the electronic age more quickly. The improve the quality of life. Especially with the development of computer, there has been a significant improvement.Corresponding to the improvement of computer technology, there is a corresponding improvement in electronics. Through it, we can not only cultivate our ability in practice, but also further develop our thinking ability and understanding of knowledge. By linking theory with reality, we can raise our ability to a new and higher level.
Responder is a priority judgment circuit designed for contestants to answer questions in a wide variety of competitions. Its application is very extensive, such as in various knowledge contests, entertainment contests and other occasions. There are many ways to realize the function of answering device,For example, a circuit-based circuit and a digital circuit are combined. . But these methods have many shortcomings, such as complex production process, low reliability in accuracy, large area of finished products, difficult installation and maintenance. We adopt an eight-way answering device with single-chip computer as the core, which is used to control logic and generate signals. types and functions of SCM, its application technology has become more mature, and its application field has been expanding.The status of the microcontroller is irreplaceable. MCU application technology has now become a new application in engineering technology. [资料来源:Doc163.com]
