摘要 本设计是以AT89S52单片机为核心设计的一个用于篮球比赛的篮球计时计分器。主要用于在篮球比赛记录整个赛程的比赛时间和显示甲、乙两队在比赛过程中的比分情况。采用单片机控制这个系统按键操作使用简，安装方便。解决了篮球比赛计数器的安装问题，节约了线材，适合在各种规模的体育场馆使用，完全可以代替传统的用钟表进行计时的方法，当然稍加改动也可以用于其他球类比赛，是体育器材向智能化发展的一个实例。Summary The design is based on AT89S52 microcontroller as the core design of a timing for the basketball game basketball scoring device. Mainly used in the process of recording the entire basketball game schedule game time remaining and display A, B teams score during the game situation. The time scoring devices have components: the part used to implement timing functions, the basic principles similar alarm clock and timing; another part of the scoring functions used to implement its basic principle and counters are similar, but want to record and display the object keys press the number of times, each time you press the count plus one or plus two.T0 interrupt timer chip used for timing, LED display shows time remaining part into the game, both teams score displayed in two parts. One time display and display the score in part by the two common cathode LED display. Time display portion can be divided into units of time to adjust. Part of the score display can manually change the field after halftime, two display modules are used to display dynamic scanning. Using an independent key buttons control part, a total of eight buttons and achieve the adjustment, adjust the time, the game start / pause, reset button and key exchange sites and so on. In part by the buzzer alarm plus three tube drive to achieve a given end button and voice alarm function.Single-chip control button operation makes the system easy to use, easy to install. Basketball game to solve the problem of counter installation, saving wire, suitable for sports venues of all sizes to use, can replace the traditional methods used for timing clocks, of course, a little change can also be used for other ball games, sports equipment to the intelligent development of an instance. 目录 摘要 0 Summary 1 目录 2 1 概述 3 1.1单片机简介
