摘 要
隨著單片機(jī)在各個(gè)領(lǐng)域的廣泛應(yīng)用，許多用單片機(jī)作控制的計(jì)時(shí)計(jì)分系統(tǒng)也應(yīng)運(yùn)而生，如用單片機(jī)控制LCD液晶顯示的計(jì)時(shí)計(jì)分器，用單片機(jī)控制LED七段顯示的計(jì)時(shí)計(jì)分器等。本文設(shè)計(jì)了一種由AT89C51型號(hào)單片機(jī)編程控制LED七段數(shù)碼管作顯示的籃球賽計(jì)時(shí)計(jì)分系統(tǒng)，并仿真實(shí)現(xiàn)。該系統(tǒng)具有賽程時(shí)間設(shè)置，賽程時(shí)間暫停，以及即時(shí)刷新甲乙兩隊(duì)比分，上下半場(chǎng)交換比分，時(shí)間結(jié)束報(bào)警等功能。此外，該系統(tǒng)具有低功耗、可靠性、安全性以及低成本等特點(diǎn)，可廣泛用于學(xué)校和小團(tuán)體作為賽程計(jì)時(shí)計(jì)分。

Abstract
With the extensive applications of the MCU, many system of timing and scoring which is controlled by MCU have come into being, for example the timing and scoring indicator displayed by the LCD which is controlled by MCU, and the timing and scoring indicator displayed by the MCU controlled seven-segment numeric display. In this article, the author designed a timing and scoring system for the basketball game showed by the seven-segment numeric display and it was programmed and controlled by the MCU in type AT89C51. This system has realized its simulation implementation. This system has various functions, such as setting and suspending the time of the game schedule, refreshing the results of the two groups and the point exchanging the places of the scores after shift their playgrounds and giving alarm when the game is over.Besides,this device owns the characters of low power consumption, reliability, safety and low cost, etc. the system is popular among the schools and group as a match schedule timing and scoring indicator.
