摘 要:抢答器在现实社会中有着很多的运用,而且设计多样化,主要是用来实现比赛的抢答作用。传统抢答器只能判断出抢答是否成功,而现在的抢答器可以通过倒计时,蜂鸣器报警等来实现抢答结果的准确和公平性。本文主要设计了一个可以实现倒计时功能、显示抢答选手号码、抢答分数的抢答器。它主要由主控制模块、分频模块和动态数码管扫描模块组成,包括一位裁判和三位选手。本系统基于VHDL语言,采用Altera公司开发的Cyclone系列EP1C3T100C8N型号的FPGA核心开发板,进行硬件测试。硬件测试表明系统能够正确显示最先抢答的选手号码,能够对答题进行5s的倒计时以及复位重新抢答,并对答题正确的选手进行加分。93989

Abstract: Responders in the real world has a lot of use, and design persification, mainly used to achieve the game's answer role。 The traditional answer device can only determine whether the success of the answer, and now the respondents can countdown, buzzer alarm to achieve the answer to the results of the accuracy and fairness。 This article mainly designed a countdown function can be achieved, show the number of players to answer, answer points score of the answer device。 It is mainly composed of main control module, frequency module and dynamic digital tube scanning module, including a referee and three players。 The system is based on VHDL language, using Altera Corporation developed Cyclone series EP1C3T100C8N model FPGA core development board, the hardware test。 Hardware test shows that the system can correctly display the first player to answer the number, to answer the 5s countdown and reset the answer, and the correct answer to the players to add points。
