摘 要

 本論文的論題是6路搶答器的設計。隨著人們生活的日益豐富，搶答器走入了人們的生活，已漸漸被人們所熟知。在一些團體的知識競賽中有著廣泛的應用，它能迅速、客觀地分辨出哪位選手最先按下的搶答鍵，大大增強了比賽的公平性，更全面的體現了選手們的實力，增加了選手和觀眾的興趣，給人們帶來了很大的方便。而隨著科學技術的不斷發展，以單片機作為主控制器的搶答器，占據了主要的地位。在功能方面，相比較而言，也增加了很多；在電路設計方面，做到了電路簡單方便。
 此6路數字搶答器的設計思想是軟硬件結合，以單片機為基礎，匯編程序為核心。搶答器有搶答功能,顯示功能,搶答限時,答題限時,時間設定,蜂鳴報警。
 
 關鍵詞：搶答器；顯示電路；報警電路；

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;
