摘要
本实习实验设计的是一个智力竞赛的抢答器，文中一共设计了三种方案，跟着分步进行方案的选择，以及进行器件的选择，考虑到利用了各个器件的特性，对设计电路时把该抢答器所完成的功能分成了几部分来实现，同时也对实际与理论上的一些小问题，进行处理。
在对各个器件都进行了选择后，再通过调试工作验证了其选择的正确性。
智力抢答器主要由抢答电路，显示电路，报警电路，记分电路几个部分构成。
各个部分介绍如下：
抢答电路具备数据锁存和显示的功能。它的功能主要是能分辨出选手按键的先后，并锁存优先抢答者的号码，提供给译码显示电路，其次是当有选手抢答时，使后抢答的选手再抢答时无效，直到主持人清零，进行下一次抢答。
显示电路的功能是在抢答电路中被锁存优先抢答者的编号数据通过译码器，然后输出控制各组下对应的发光二极管工作，显示出先抢答选手的号码。
报警电路是当LED数码管显示最先动手的选手的编号的同时，由报警电路发出延续两秒的音响，这个设计所用的是由555定时器和三极管构成报警电路，以此提醒主持人和观众先抢答的选手的编号。
记分电路其功能是能预置各组起始分，再由主持人对每组的答题情况进行加减分，并用三只LED数码管做出计分显示，体现出各组的成绩。由此所组成的电路能实现智力竞赛抢答器的功能。
本设计中所用到的关键
通过选择好的芯片实现6选手抢答器使其具有锁存、主持人置零、正确显示抢答成功选手，和记分的功能。

ABSTRACT：
What this practice experiment design is an intelligence to contest of rob the answer machine, designed three kinds of projects in the text, come after to divide a choice for proceeding the project, and proceed the machine a characteristic for of choice, in consideration of making use of each machine piece, to design the hour in electric circuit also main of with theoretically some small problem, proceed to handle.
At to each machine an accuracy for all proceeding choice empress, then passing adjusting trying work verifying its choice.The intelligence robs the main cent in answer machine robs the answer electric circuit, manifestation electric circuit, report to the police the electric circuit, record to divide electric circuit several part.Each part the introduction is as follows:
Robbing the answer electric circuit has the data lock save with the function of the manifestation.It of function primarily is to distinguish the contestant key successively, and lock to save to have the initiative the number that rob the answer, provide to translate the code manifestation electric circuit, is a contestant to be contestant rob the answer, rob the answer after making to rob again the hour of answer the next in order invalid, until pure zero in host, proceed the next time rob the answer.
Function that show that the electric circuit is locked to save to have the initiative the serial number data that rob the answer in rob answer electric circuit pass to translate the code machine, then output a next rightness should of give out light the diode work
Reporting to the police the electric circuit is the serial number of the contestant to be the LED figures tube manifestation to begin first at the same time, from report to the police the electric circuit send out to continue two seconds stereo sets, what this design use is from 555 settle the machine constitute to report to the police the electric circuit with the triode transistor, reminding the host to rob the serial number of the contestant of the answer with audience first with this.
Recording the each answer a circumstance for dividing its function in electric circuit is can prepare place each start divide, the next in order to proceeds the each score for adding and subtract cent, counteract three LED figures tube do out account cent show, appear.
From here an electric circuit for constituting can realize the function that intelligence contest rob answer machine.
