基于单片机控制的便携式篮球计时器设计

随着篮球运动的普及，为了解决偏远贫困山区篮球比赛和小团体外出比赛的计时问题，利用AT89C51芯片控制能力强，设计灵活，以及编程语言易于修改等优点，采用软件设计和硬件设计相结合，设计了该便携式篮球计时器，利用KeilμVision3运行程序、调试时间、运行步骤，将写好的程序导入仿真硬件电路中，查看是否与设计要求一致。该设计具有性能稳定，功耗低，价格便宜，易于携带等特点。

Design of Portable Basketball Match Timer Controlled by Single-chip Microcomputer

In combination with the software design and hardware design, a portable timer for basketball match was de- signed by utilizing AT89C51 chipts strong control ability; the design flexibility and programming language easy to modify to overcome the timing difficulties of the basketball games in remote impoverished mountainous areas and the basketball games between cliques, and adapt the popularization of basketball game. The written program is imported into the simulation hard- ware circuit to see whether this design agrees with design requirements by using Keil uVision 3 to run the program and debug the operation time. The design has the characteristics of performance stabilization, low power consumption and low price, and is portable.
