摘 要
反应速度是指人体对刺激发生反应的快慢。反应速度通常用“从刺激到开始发生反应的时间”,即反应时来衡量。目前，国内外常用反应时指标研究运动员的机能状态及心理活动过程。反应速度是人类的基本生理素质之一。以AT89S52单片机为核心的人体反应速度测试仪，主要控制测试灯的状态，通过测试按键的状态来间接计算人体反应速度。实验测试表明，系统测试精度高、抗干扰能力强、反应测试较为准确，具有一定的参考价值。同时因为其结构简单、体积小、成本低、扩展方便，在反应速度测试中有广泛的应用前景。 关键字：单片机 AT89S52 反应速度
ABSTRACT
Reaction speed is refers to react to stimulate the body responds to it. Reaction speed usually use "from stimulation to start happening reaction time", i.e., reaction time measurement. At present, the domestic and international common reaction index research status and the function of athletes psychological process. Reaction speed is one of the basi
c human physiological quality. AT89S52 SCM as the core in the human body reaction velocity tester, main control test lamp state, through the test buttons to indirect calculation human reaction state pace. Test results show that system testing precision, strong anti-jamming capability, reaction test is more accurate, to have the certain reference value. Also because of its simple structure, small volume, low cost, convenient, in the reaction speed expansion tests have broad application prospect红外焦平面探测器>手机展示架
