摘 要

本论文的论题是6路抢答器的设计。随着人们生活的日益丰富，抢答器走入了人们的生活，已渐渐被人们所熟知。在一些团体的知识竞赛中有着广泛的应用，它能迅速、客观地分辨出哪位选手先按下的抢答键，大大增强了比赛的公平性，更全面的体现了选手们的实力，增加了选手和观众的兴趣，给人们带来了很大的方便。而随着科学技术的不断发展，以单片机作为主控制器的抢答器，占据了主要的地位。在功能方面，相比较而言，也增加了很多；在电路设计方面，做到了电路简单方便。

此6路数字抢答器的设计思想是软硬件结合，以单片机为基础，汇编程序为核心。抢答器有抢答功能,显示功能,抢答限时,答题限时,时间设定,蜂鸣报警。

关键词：抢答器；显示电路；报警电路；

Abstract

Present paper‘s thesis is 6 groups vie to answer the first design. Lives day by day richly along with the people, vied to answer first has walked into people’s life, had been known very well gradually by the people. Has the widespread application in some association‘s knowledge competition, can it rapid, which contestant distinguish to press down first objectively vies to answer the first key, strengthened competition’s fairness greatly, more comprehensive has manifested contestants‘ strength, increased the contestant and audience’s interest, has brought very big convenient to the people. But along with science‘s and technology’s unceasing development, takes the master-control unit by the monolithic integrated circuit to vie to answer first, occupied the main status. In function aspect, comparatively speaking, also increased many; In the circuit design aspect, has achieved the electric circuit simply convenient. This 6 groups digit vie to answer the first design concept is the software and hardware union, take the monolithic integrated circuit as the foundation, the assembly program is the core. Vies to answer first has vies to answer the first function, demonstrates the function, vies to answer the first time limit, the answer time limit, the time setting, the buzzing warning. Key word: Vies to answer first; Display circuit; Alarm circuit;
