Based on singlechip product automatic counter intuitive and count accurate advantages, currently have in various industries have been widely used. Digital counter have various forms and generally have contact and contactless two kinds, in the development of science and technology today, contactless infrared counter been widely used. The design USES a pair of infrared emission receiving tube as infrared counter signal detection head, is inexpensive, antijamming good, simple structure, convenient operation, etc. 無(wú)錫科技職業(yè)學(xué)院畢業(yè)論文 2 The guiding ideology is using infrared luminescence tubes launch infrared, infrared receiving tube receiving this infrared, and put the amplification, rectifier form low level signals. When someone or something blocking infrared, receiving tube without receiving infrared signal, amplifier output high level, at the same time will the level signal into SCM control counted, and making digital tube display Numbers. So get to statistics, the number of people or things. Keywords: Automatic counting， MCU， Digital tube 無(wú)錫科技職業(yè)學(xué)院畢業(yè)論文 3 目 錄 摘 要 ............................................................................................................................. 1 Abstract ........................................................................................................................... 1 前言 ................................................................................................................................. 4 第一章 計(jì)數(shù)器的概論 ................................................................................................... 5 選題背景 ............................................................................................................. 5 國(guó)內(nèi)外的研究概況 ............................................................................................. 5 第二章 控制要求分析 ................................................................................................... 6 設(shè)計(jì)要求 ............................................................................................................. 6 題目分析 ............................................................................................................. 6 整體構(gòu)思 ............................................................................................................. 6 第三章 主要元器件的概述 ........................................................................................... 8 AT89S52 單片機(jī)的引腳及其功能 ...................................................................... 8 光電式傳感器（光電開(kāi)關(guān)） E18D80NK ...................................................... 11 數(shù)碼管 ............................................................................................................... 14 第四章 計(jì)數(shù)器控制系統(tǒng)設(shè)計(jì) ..................................................................................... 16 單片機(jī)系統(tǒng)程序設(shè)計(jì)流程 ..........................................
