摘要
隨著計(jì)算機(jī)技術(shù)的高速發(fā)展，單片機(jī)以其自身的特點(diǎn)，已廣泛應(yīng)用于智能儀器、工業(yè)控制、家用電器、電子玩具等各個(gè)領(lǐng)域。在知識(shí)競(jìng)賽中，特別是做搶答題目的時(shí)候，靠視覺(jué)是很難判斷出哪組先搶答成功。利用單片機(jī)系統(tǒng)設(shè)計(jì)的搶答器，可使問(wèn)題得以解決，即使兩組的搶答時(shí)間相差幾微秒，也可分辨出哪組優(yōu)先答題。
本次設(shè)計(jì)的4路搶答器主要是采用ATMEL公司的AT89S51單片機(jī)作為核心，實(shí)現(xiàn)控制4個(gè)獨(dú)立式鍵盤(pán)搶答按鈕，單位靜態(tài)數(shù)碼顯示，手動(dòng)復(fù)位等功能。控制系統(tǒng)的五個(gè)模塊分別為：?jiǎn)纹瑱C(jī)最小系統(tǒng)、顯示模塊、搶答開(kāi)關(guān)模塊和音頻輸出模塊，搶答組數(shù)可以在四組以?xún)?nèi)任意使用。通過(guò)本設(shè)計(jì)后，可以很快的判斷出是誰(shuí)最快搶答成功，并且馬上進(jìn)入答題倒計(jì)時(shí)，比賽即將結(jié)束時(shí)，能發(fā)出報(bào)警聲，同時(shí)在顯示模塊上顯示出倒計(jì)時(shí)時(shí)間的提示。

Title   Sound and light show quiz Responder
Abstract
With the rapid development of computer technology, SCM with its own characteristics has been widely used in intelligent instruments, industrial control, household appliances, electronic toys and other fields. Competition in knowledge, especially when answering Device, by which the visual is very difficult to determine the successful group the first answer. Using MCU system design Responder, the problem can be solved, even if the time difference between the two groups answer in a few microseconds, can tell which group first answer.
The 8-way system design is the use of devices Answer Atmel Corporation AT89S52 single-chip microcomputer as the core, to achieve control of eight stand-alone keyboard answers in the button, the four dynamic digital displays, and manual reset functions. The control systems of the five modules are as follows: the smallest single-chip system, display module, display driver module, answer switch module, and the audio output module, answer a few groups can be less than the arbitrary use of eight groups. Through this design, you can quickly determine who is the fastest answer in success, and immediately enter the answer countdown; And who answer in too early, an alarm sound and displays the group number fouls; game about the end of the alarm can be issued the same time, the display module shows time countdown tips.
