介绍一种全身反应时测试仪器,通过测量从发出信号到被测试者开始起跳的时间衡量被测试者的反应时间。仪器由单片机控制,通过模数转换电路和放大电路对踏板压力进行采样,以监测被测试者的动作。仪器还可以通过记录被测试者起跳的弹力,测量被测试者起跳时间和起跳过程的最大弹力。通过不同的声、光信号,仪器具有测量简单反应时和选择反应时两种功能。该仪器测量准确,测试方式简单,适合于学校使用。
A systemic response time test instrument is introduced to measure the response time of a test subject by measuring the time it takes for the signal to be measured before the subject starts taking off. Instrument controlled by the microcontroller, through the analog-digital conversion circuit and amplifier circuit to sample the pedal pressure to monitor the subject’s action. The instrument can also measure the elastic force of the subject to take off and measure the maximal elastic force of the subject during take-off and take-off. Through different acoustic and optical signals, the instrument has two functions of measuring simple reaction time and selecting reaction time. The instrument measures accurately, the test method is simple, suitable for school use.
