摘要: 隨著單片機在各個領(lǐng)域的廣泛應(yīng)用，出現(xiàn)了許多用單片機作控制的球賽計時計分器?；@球比賽計時計分器是為了解決籃球比賽時計分與計時準(zhǔn)確的問題。本設(shè)計以基本籃球規(guī)則為依據(jù)，可對籃球比賽比分實現(xiàn)控制，利用單片機AT89C51完成計時計分的功能。設(shè)計包括單片機AT89C51，計時顯示電路，計分顯示電路，報警電路和按鍵開關(guān)。24秒顯示能按鍵控制24秒計時器，當(dāng)控球時間超過24秒時，可發(fā)出警告音，報警部分采用蜂鳴器作為音響器件。計時器在每次暫停時自動開動計秒表且比賽在暫停時間，在每節(jié)結(jié)束或決勝期間時間終了可自動用非常響亮的信號通知。記分器可記錄兩隊的積累分?jǐn)?shù)。在計分過程中，若出現(xiàn)計分錯誤，還可以通過按鍵進(jìn)行修改（根據(jù)具體情況可加減一分，兩分，三分）。 關(guān)鍵詞：單片機；計分；計時；報警；顯示
Abstract:With the microcontroller widely used in various fields, a microcontroller for control of match timer and scoring device is used. Basketball game timing scoring is accurate scoring and timing in order to solve the game of basketball. This design is based on the basic rules of basketball, basketball game score control, AT89C51 microcontroller to complete the timed scoring function. The design includes a microcontroller AT89C51, the time display circuit, scoring a display circuit, alarm circuits and key switch. 24 seconds button control 24 seconds timer which issue a warning sound when the ball for more than 24 seconds and alarm parts buzzer as the audio device. The stopwatch timer automatically start each time you pause the game in the pause time at the end of each section or extra time during the end of a very loud signal notification automatically. The scoring can record the accumulated scores of the two teams. In the scoring process, if a scoring error, the keys can also be modified (as the case may be plus or minus one, two or three points). Key words: Single chip microcomputer, scoring, timing, alarm, display
