Development And Application Of Multi-function Reaction Time Tester

With the continuous improvement of production and living conditions, there is agrowing emphasis on the ability to identify and respond quickly to external stimulireaction, reaction time and therefore characterization of the rapid reaction capabilityof the human community has become the focus of attention and research. With theadvancement of science and technology, the reaction test tools are also increasinglyprecise, complex, reaction time test applications are increasingly widespread. Atpresent, the reaction is widely used in the determination of medicine, pharmacy,public health, psychology and other basic research and practical work to the attentionof the evaluation, the evaluation governance evaluation, psychological evaluations,working ability, athletic ability and so on. In modern studies, it is one of theimportant indicators of certain career choices, to determine the psychological cardrivers, pilots, astronauts and athletes, the possibility has important physiologicalsignificance.When measuring the reaction time can not be separated using the analyzerresponse, reaction analyzer function will directly affect the accuracy of theexperimental results of the reaction. This paper introduces the design and applicationof multi-functional HMI reaction time test device. When this study developed a testresult is more accurate and efficient reaction test device, the device uses a51microcontroller as the core of the whole control system of the original, the use of Clanguage programming, multi-terminal while testing, changing only the generalreaction tester one of the drawbacks can test subjects; at the same time, for manybasic functions to improve the design, optimization of the test device, theinterference of the external environment weakened psychological experiments toimprove the accuracy of results, reliability; by increasing steering wheel and brakepedal to realize their professional competence test driver with the addition of thestarting blocks, and other design elements to realize their professional competence test athletes to ensure the basic research and the work of the evaluation functionmore close to reality; and to work out a standardized test process, the processingmethod of test data have been unified to ensure the test results were comparablebetween different experiments, to further improve the reliability of the test; the lastinstance by means of this application, further analysis demonstrated the accidentresponse and production the relationship between the reference for the productionsafety management.
