摘　　要：计数器在人们日常生活中应用越来越多,已成为不可缺少的必需品。本文介绍了红外计数器的发展前景和现状,设计了一种由数字电路来实现的红外计数器,详细阐述了红外计数器的工作原理和构成,讨论了各模块的实现方法,并对它们进行了严格的理论逻辑推敲和实验测试,以达到设计要求。它可以解决计数中的增减问题,对任意流水线产品及来往客流自动计数。因此,研究红外计数器及扩大其应用,有着非常现实的意义。Counters are widely used in our daily life and gradually become a necessity. Here we introduce the current status and also the future of infrared counters, then present a design on top of digital circuit. And the working theory and construct are described and implementation of each module is discussed here. Strict logical reasoning and real experiments have approved each step is correct in the process which have fulfilled the design specifications. To summarize, infrared counters can solve increase/decrease prob- lem in counting, such as automatic counting for industrial pipelining and traffic. Therefore, the study of infrared counter and expanding its applications make very practical sense in above terms.
