摘要尽管随着社会的发展，娱乐活动变的多样化。抢答这种传统的游戏还是经久不衰。现如今不管是在各种电视综艺节目中，还是日常生活中，抢答游戏随处可见。然而如何保证抢答的公平公正，怎么使抢答游戏更加简单便利，正是这次研究的目的。95122

这研究的课题——基于单片机的八路抢答器设计，本此设计以简单高效为原则。目标设计一套功能全面但又结构精简的抢答器系统。本文设计围绕89C51，通过软件程序组合各种模块，达到设计目的。主要模块有选手和主持人使用的按键模块、用来显示抢答信息的数码管显示模块、用来警告提醒选手的发生模块和其他辅助模块。本文由点及面地描述了设计的细节内容和设计过程。

此次设计的抢答系统可以实现：显示抢答选手编号的同时亮灯并发声提示、误抢答显示编号并发声警告选手、最后5秒无人抢答发声提醒、二次抢答记忆功能、倒计时时间设置功能、特殊情况系统复位功能。

本文包含了整体的设想和各个部分的介绍及设计思路，软件和硬件的设计调试，全面而细致的展现了整个方案由设想到设计到落实到完成的整个过程。

精简的结构和丰富的功能，使这套抢答器设计更迎合大众要求，更便于普及到各人各家。使人们能不限时间和地点的，享受抢答游戏所带来的愉悦的心情。

Abstract Although with the development of society, recreational activities become persified。 Answer this traditional game or enduring。 Now, whether in a variety of television variety shows, or in daily life, answer the game can be seen everywhere。 However, how to ensure a fair answer in answer, how to make answer the game more simple and convenient, it is the purpose of this study。

The subject of this research - based on the eight-way single-chip Responder design, this design is simple and efficient principle。 Objective To design a comprehensive but compact structure of the Responder system。 This design around the 89C51, through the software program combination of various modules, to design purposes。 The main module has a key module used by the player and the host, a digital display module for displaying the answer information, and a warning module for warning the player and other auxiliary modules。 This paper describes the design details and design process from point to point。

The design of the answer system can be achieved: the number of players in the display while answering the number of lights and sound tips, show the number and the wrong answer in the sound of warning players, the last 5 seconds no answer in voices to remind the second answer in memory function, the countdown time setting function, Special case system reset function。

This article contains the overall vision and the introduction of various parts and design ideas, software and hardware design and debugging, comprehensive and detailed display of the entire program from design to design to implementation to completion of the whole process。

Streamlined structure and rich functionality, so that this set of responder design to meet the public requirements, more accessible to everyone。 So that people can not limit the time and place, and enjoy the joy of answering the game brought the mood。
