摘要
本设计是采用单片机AT89C51作为本设计的核心元件。利用7段共阳LED作为显示器件。在此设计中共接入了8个7段共阳LED显示器，其中4个用于记录AB队的分数，每队2个LED显示器显示范围可达到0~99分，足够满足赛程需要，另外4个LED显示器则用来记录赛程时间，其中2个用于显示分钟，2个用于显示秒钟。赛程计时采用到计时方式。即比赛前将时间设置好，比赛开始时启动计时，直至计时到零为止。计时范围可达到0~99分钟，也完全满足实际赛程的需要。
其次，为了配合计时器和计分器校正调整时间和比分，我特定在本设计中设立了11个按键，其中8个用于设置，交换场地，启动和暂停等功能。采用单片机控制是这个系统按键操作使用简洁，LED显示，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。

Answer 1

This design is uses monolithic integrated circuit AT89C51 to take this design the core part. Takes the display device using 7 section of altogether positive LED. Designed the Chinese Communist Party in this to turn on 8 7 section of altogether positive LED monitors, 4 used in recording the AB team the score, each team 2 LED monitor demonstrated that the scope might amount to 0~99 points, enough met the competition schedule needs, other 4 LED monitor used for to record the competition schedule time, 2 used in demonstrating the minute, 2 used in demonstrating the second. The competition schedule time selects the time method. Before namely the competition, establishes the time, the competition starts when starts the time, until times till zero. The time scope may amount to 0~99 minutes, also satisfies the actual competition schedule completely the need. next, to coordinate the timer and the string adjusts the time and the score, I have set up 11 pressed keys specificly in this design, 8 use in establishing, changes courts, functions and so on start and suspension. Uses the monolithic integrated circuit control is this system pressed key operation use is succinct, LED demonstrated that easy installation. Solved the basketball game counter to install the question, saved the wire rod, suited in each scale sports complexes use, definitely might replace the tradition to carry on the time with the clock and watch the method, modified certainly slightly may also use in other ball games competition, was the sports equipment to a intellectualized development example. 不对不要分！

Answer 3

The design is a single-chip microcomputer AT89C51 as the core components of the design. Yang paragraph 7 of use as a display LED. In this design access to the Chinese Communists in paragraph 7 of 8-LED display, which used to record four scores AB teams, each team two LED display showing the scope can reach 0 to 99 points, enough to meet the schedule needs of the other four LED displays are used to record the time schedule, which used to show two minutes, two seconds for the display. Fixtures time to time using methods. That the game would be a good time to set up, the game started at the beginning of time, up until the time to zero. Timing can be achieved range 0 to 99 minutes, and fully meet the needs of the actual race.
Secondly, in order to tie in with the timer and the points for correction and adjustment比分time, I specified in the design of the establishment of the 11 keys, of which eight to set the exchange venues, initiation and suspension functions. SCM control is a key to operate the system simple, LED display, ease of installation. Solve the basketball game counter installation, saving the wire for the stadiums of all sizes use, and can fully replace the use of traditional methods of watches and clocks for timing, of course, it would also be used for other sports competitions, sports equipment to the development of an intelligent example.
