摘要
该系统以核心部件AT89C51单片机作为智能控制部分,光电感应系统由一对收发光电管来进行信号检测,将运动员阻挡的信号转化为电信号,再由电信号转化为跳远值,该设计以C语言为编程语言,单片机AT89C51与PC级之间进行信号传输,使立定跳远测试实现自动化测量,测试结果由LCD液晶显示,提高了测试精度和效率。
The system AT89C51 microcontroller as the core components of intelligent control section, photoelectric sensor system consists of a pair of transceivers for signal detection photocell,blocking the signals into electrical signals athletes,then by the electrical signal is converted to long jump value,the design with C language programming language,for signal transmission between the microcontroller AT89C51 and PC level,so that the standing long jump test to automate the measurement,the test results from the LCD display to improve the test accuracy and efficiency.
