基于STC89C52单片机跆拳道比赛计时计分系统设计与实现

Design and implementation of timing and scoring system of Taekwondo match based on STC89C52

采用STC89C52单片机进行控制,设计并实现了一套跆拳道比赛计时计分系统。在进行跆拳道比赛时,可以在计分器上同步显示参赛队伍双方实时得分。该计时计分系统的特点是在比赛进行到一半需要交换场地停止计时,以及在每节比赛结束时发出提示音,三组四位的数码管上分别显示两位参赛队伍的得分情况以及比赛结束倒计时读秒。系统控制程序使用C语言来进行编写,控制程序开发平台选用Keil集成开发平台,在软件调试编译完成之后使用软件Proteus进行系统仿真。经过仿真论证,基于STC89C52单片机跆拳道计分系统不仅计时计分准确,而且系统操作方便,运行可靠。

STC89C52 single chip microcomputer is used to control,design and implement a Taekwondo match timing and scoring system.In Taekwondo competition,the real⁃time scores of both players can be synchronously displayed on the scorer.The timing and scoring system is characterized by stopping the timing when half of the competition needs to be exchanged,and sending a prompt tone at the end of each competition;the digital tube of three groups and four positions respectively displays the scoring of two competitors and the countdown of the end of the competition;the system control program is written in C language,and the control program development platform is Keil integrated development platform,after the completion of software debugging and compiling,use software Proteus for system simulation.After the simulation,the Taekwondo scoring system based on STC89C52 is not only accurate in timing and scoring,but also convenient and reliable in operation.
