1、 篮球赛计时计分器设计 院 系 自动化学院 专 业 自动化 班 级 学 号 姓 名 指导教师 负责教师 2008 年 6 月 毕业设计（论文） - - I 摘摘 要要 体育比赛中的计时计分系统是对体育比赛过程中所产生的时间、 比分等数据信息 进行快速采集、加工处理、传递和利用的系统。此系统能否清晰、稳定、精确的反应 体育比赛中的客观数据，直接影响到比赛的公平性和公正性。本文针对上述情况研制 了篮球赛计时计分器。该系统以单片机为核心，利用7段共阴LED作为显示器件。为 了调整比赛中的时间和比分，在本设计中设立了8个按键，分别用于记录甲、乙两队 的分数，设置赛程时间，调整赛程时间，启动和暂停赛程时
2、间等功能，本系统还设计 了定时报警系统。实践证明，该系统精度高、稳定性好、抗干扰性强，具有一定的应 用前景。 关键词：计时器；计分器；单片机；LED显示 毕业设计（论文） - - II Abstract The system of time and score recorded in the sporting games is the one like this: the data about time and socres that generated in the process of the games can be collected rapidly, processed, trans
3、mited and be used. If the system can reflect the objective data in the games clearly, stably and accurately, it will affect the fairness and impartiality of the games. According to this, calculagraph and scores recorder of the basketball games are researched and designed in this paper. The core of t
4、he system is the MCU, using seven segments LED as the display. In order to adjusting the time and the scores of the game, eight keys are used in this paper. The functions of these keys are: recording the scores of the team A and B, setting up or adjusting the time of the game, and starting or suspending the time of the game. The timing alarm system is also designed in the system. Experiments has proved that the system has high precision, good stability, strong anti-interference and it
