单片机应用系统是为完成某项任务而设计、研制和开发的应用系统，是以单片机为核心，配以外围电路和软件，能实现给定任务和功能的实际工程应用系统。在有A、B两方参加的比赛中，例如羽毛球赛、乒乓球赛、足球赛、排球赛、篮球赛，经常需要进行加分和减分的计分操作，本文设计并从硬件和软件上完成了一种以AT89C51单片机为微处理器的，能显示A、B两方3位比赛成绩（0—255分）的以上几种赛事的通用比赛计分显示系统。该系统价格低廉，实现简单。

Applied system of AT89C51 Single Chip Microcomputer is designed,researched and developed to complete a specific prograrm To be exact, it is a type of practical applied system, which can fulfill given tasks operated by Single Clip Microcomputer with its peripheral circuit and software. In the games such as badminton,table tennis,football,vol- leyball and basketball, there is common need for plus and minus point scoring between both sides A and B. This paper designs a cheap, simple and practical AT89C51 Single Chip Microcomputer with complete hardware and software, which can display game scores within three- digit numbers (0 -255 ) and can be generally used in the games mentioned a- hove.
