單片機(jī)畢業(yè)設(shè)計(jì)-籃球比賽倒計(jì)時(shí)計(jì)分器(論文+外文翻譯+程序)

摘 要
籃球比賽計(jì)時(shí)計(jì)分器是為了解決籃球比賽時(shí)計(jì)分與計(jì)時(shí)準(zhǔn)確的問題。此裝置利用單片機(jī)AT89C51完成了計(jì)時(shí)和計(jì)分的功能。本文詳細(xì)地介紹了系統(tǒng)硬件與軟件的設(shè)計(jì)過程，采用該裝置可根據(jù)實(shí)際情況進(jìn)行比分修改和時(shí)間的準(zhǔn)確顯示，具有低功耗，可靠性，安全性以及低成本等特點(diǎn)。

關(guān)鍵詞：單片機(jī)，籃球賽計(jì)時(shí)，籃球賽計(jì)分 

 
Abstract
Along with the technical and quick development in electronics, appear with the large-scale integrated circuit especially, give mankind the life brought the changes of the root. The coal gas reports to the police the system publishes, scribing the electronics measure the instrument walked into the arithmetic figure turns the ages its function is strong, the function is well-found, technique forerunner, will quickly technical development in science.
In the hardware aspect, except the monolithic outside the aircraft, uses ten seven section of led nixie tube s to carry on the demonstration, LED uses is the motionless scanning demonstration, uses the 74LS21 chip to carry on the actuation.
With the coal of compilation, we can get the functions of this design such as keeping scores, recording the time, and that we can alternate with the scores of both teams. It’s practical and simple to accomplish.

Key words: Single Chip Microcomputer ,led nixie tube ,keeping scores and the time
