摘 要

当今世界，喜欢篮球运动的人越来越多，篮球运动不仅能增强人们体质，还能增加人与人之间的友谊。篮球运动也是本着公平、公开、公正的原则而开展的，这是对每个运动员的尊重，也能提高人们参与比赛的积极性。篮球比赛通过比赛时间和分数来决定胜负，所以在篮球比赛中对时间和分数的准确记录与合理计算十分重要，因此，篮球计时计分系统的研究对于提高篮球比赛的质量至关重要。

此次设计是通过51单片机系统对篮球比赛的时间和分数进行记录和处理，利用数码管进行分数的显示和更新，通过设定一系列的按键对单片机传递控制信息，同时还加入蜂鸣器作为比赛开始结束的提醒工具。这套装备主要兼顾到成本与性能两大方面，单片机价格低廉、普及广、操作简单同时也具备着较高的稳定性和准确性，外围器件也都经过多次考虑计划后选取的。整个系统主要具备着生产成本低、材料广泛、操作简单、功能强大、稳定性好的特点，具有很大研究意义。

ABSTRACT

In today's world , more and more people like to play basketball . Basketball can

not only enhance the people’s physique , but also increase the friendship between

people . Basketball is also carried out in line with the principle of fairness , openness

and justice . This is for each athlete’s respect , at the same timeimprove the

enthusiasm of people to participate in the competitI/On . The basketball game by

game time and scores to determine the outcome , so in the basketball match on time

and accurately record the scores and reasonable calculatI/On is very important .

Therefore , study on basketball timing and scoring system is very important to

improve the quality of the game of basketball .

This design is recorded and processed the basketball game time and scores by 51

single chip microcomputer system, by using digital tube to display concentratI/On and

update the scores.by setting a series of key control informatI/On tranfer to single chip

microcomputer,at the same time as the start and end of a match with a buzzer

reminder tool . This set of equipment is mainly to take into account the cost and

performance aspects . Single chip is cheap , popularzatI/On , simple operatI/On , but

also has a high accuracy and stability . Peripheral devices are also selected after

several considered . The whole system has a low productI/On cost , wide range of

materials , simple operatI/On , strong functI/On and good stability . This design has

great significance .

Key words Timing scoring system , 51 single chip , performance , design
