摘要
篮球计时计分器以单片机为核心,由计时器、计分器、综合控制器等组成。系统采用模块化设计,主体分为计时显示模块、计分显示模块、定时报警、按键控制键盘模块。每个模块的程序结构简单、任务明确,易于编写、调试和修改。编程后利用Keil软件来进行编译,再将生成的HEX文件装入芯片中,采用Proteus软件仿真,检验功能是否能够正常实现,本设计中系统硬件电路主要由以下几个部分组成:单片机AT89C52、计时电路、计分电路、报警电路和按键开关。该系统具有赛程定时设置、赛程时间暂停、及时刷新甲乙双方的成绩以及赛后成绩暂存等功能。

ABSTRACT
Time basketball scoring device as the core of SCM includes the timer, scoring devices, integrated controller and system is used of the modular design, in which the main display module is divided into time display module, scoring display module, timing alarm module, and key control keyboard module. Program structure of each module is simple and clear. So it is easy to write, debug and modify. After programming, firstly we can use Keil software pile and then generate the HEX file into the chip. Secondly we use the Proteus software simulation to test whether the normal function to achieve. The design of hardware circuit mainly consists of the ponents, including AT89C52, timing circuit, scoring circuit, alarm circuit and key switch system has many features,such as setting the schedule time, scheduling time to pause, refreshing result of both parties timely, storing temporarily results after the match and so on.
KEY WORDS:Microcontroller, Timing, Scoring, Display, Interface
