Actually can realize the function is way occupations, can use of the analog circuits, analog and digital circuit, or a bination of digital circuit, also can use the microcontroller, PLC, EDA, etc to achieve design contest. In recent years, with the application of SCM unceasingly thoroughly based on singlechip microputer control, the design bees more and more vies to answer first widely accepted, the mature and MCU C51 language itself is the integration of assembly language mixing programming makes it more than general assembly language have better readability. Circuit with 16 vies to answer first, for 16 people vies to answer first. Press the start button after the host, which first vies to answer first, then in digital display player on the tube, and Numbers and sound input, the other contestants blockade is invalid. The responder again, With time vies to answer first function, can be set by the host vies to answer first time. In setting time vies to answer first effectively, the timer stop working. The time has e regularly, no contest, this contest null and void. Keywords: vies to answer first, Intelligence, SCM, Digital display 東華理工大學(xué)長江學(xué)院畢業(yè)設(shè)計（論文） 目錄 目 錄 緒論 ................................................................................................................................ 1 課題研究的意義，國內(nèi)外有關(guān)本課題的研究動 態(tài)和自己的見解 .......................... 1 課題研究的意義 ........................................................................................... 1 課題研究的動態(tài) ........................................................................................... 1 自己的見解 ................................................................................................... 2 課題研究的主要內(nèi)容、擬解決的關(guān)鍵性問題和預(yù)期的成果 ................................. 2 課題研究的主要內(nèi)容 .................................................................................... 2 擬解決的關(guān)鍵性問題 .................................................................................... 2 預(yù)期成果 ...................................................................................................... 2 .......................................................................................................... 3 .............................................................................................................. 4 系統(tǒng)框圖 .............................................................................................................. 4 系統(tǒng)分析 .............................................................................................................. 4 功能模塊設(shè)計 ....................................................................................................... 5 時鐘電路設(shè)計 ............................................................................................... 8 功能分析 ...................................................................................... 8 時鐘電路硬件設(shè)計 ........................................................................ 8 復(fù)位電路設(shè)計 ............................................................................................... 9 功能分析 ...................................................................................... 9 硬件設(shè)計設(shè)計 ............................................................................... 9 搶答電路設(shè)計 ............................................................................................. 10 功 能分析 .................................................................................... 10 搶答電路硬件設(shè)計 ...................................................................... 13 顯示電路設(shè)計 ............................................................................................. 14 功能分析 .................................................................................... 14 硬件設(shè)計 .................................................................................... 15 報警電路設(shè)計 ............................................................................................. 15 控制電路設(shè)計 ............................................................................................. 16 功能分析 .................................................................................... 16 硬件設(shè)計 .................................................................................... 16 ................................................................................................................... 17 Keil C51 語言語言簡介 ..................................................................................... 17 程序流程圖 ........................................................................................................ 17 程序設(shè)計 ............................................................................................................ 18 東華理工大學(xué)長江學(xué)院畢業(yè)設(shè)計（論文） 目錄 主程序設(shè)計 ................................................................................................. 18 時鐘電路程序設(shè)計 ...................................................................................... 19 搶答電路程序設(shè)計 ....................................................
