摘 要：本設(shè)計(jì)是基于AT89C51單片機(jī)的籃球計(jì)時(shí)計(jì)分器，利用7段共陰LED作為顯示器件。在此設(shè)計(jì)中共接入了1個(gè)四位一體7段共陰LED顯示器，2個(gè)三位一體7段共陰LED顯示器，前者用來記錄賽程時(shí)間，其中2位用于顯示分鐘，2位用于顯示秒鐘，后者用于記錄甲乙隊(duì)的分?jǐn)?shù)，每隊(duì)2個(gè)LED顯示器顯示范圍可達(dá)到0~999分。賽程計(jì)時(shí)采用倒計(jì)時(shí)方式，比賽開始時(shí)啟動(dòng)計(jì)時(shí)，直至計(jì)時(shí)到0為止。
為了配合計(jì)時(shí)器和計(jì)分器校正調(diào)整時(shí)間和比分，我們特定在本設(shè)計(jì)中設(shè)立了7個(gè)按鍵，用于設(shè)置，調(diào)整時(shí)間，啟動(dòng)，調(diào)整分?jǐn)?shù)和暫停等功能。采用單片機(jī)控制是這個(gè)系統(tǒng)按鍵操作使用簡(jiǎn)潔，LED顯示，安裝方便。

Design of Basketball timing Scoring Device Based on SCM
Abstract：The design is based on AT89C51 microcontroller timing basketball scoring device, the use of 7 as a common cathode LED display.In this design, the CPC has an access to one of four 7-segment common cathode LED display, 2 Trinity 7 common cathode LED displays, the former is used to record the race of time, of which 2 used to display the minutes, 2 seconds to displayminutes, which is used to record scores and B teams, each team two LED display shows the range of 0 to 999 points can be achieved.Schedule time with the countdown mode, the game starts the beginning of time until the timer to 0 so far.
To cope with calibration timer and scoring device to adjust the time and score, we design a specific set in the 7 buttons, for setting, adjusting the time, start, adjust the score and pause functions.The system uses single chip control is to use simple button operation, LED display, easy to install.
