Reaction Time Tester Research And Development

Along with the modern development of sports technology，time factors in athleticcompetition plays a more and more important role in physiology，psychology and otherrelated fields on total body reaction time study also quite extensive，but the currentdomestic sales of instruments are of simple reaction time tester，test out systemicreaction apparatus is also not，simple reaction time test apparatus test and test dataprecision exists many shortage．In order to break through the existing instrument testrange，at the same time get rid of the traditional test method，convenient psychology，physical fitness test and other related fields of research and application，I will referencereaction time test method using vertical jump to study systemic reactions，developed inresponse to systemic reaction time test reaction time test instrument，make it’s the testresults more accurate，reliable，objective．This paper first elaborates the systemic response time tester composition structureand working principle．Reaction time tester is simple in the whole structure，convenientcarrying，simple operation of the test apparatus，is mainly composed of twe parts：thehardware part and software．The hardware part is mainly composed of a single chip，analog to digital converter，a weighing sensor，amplifying circuit，liquid crystal screen，the start button and an acoustic-optic prompting components．The software part by themodel，program flow，Ad acquisition and data analysis software．This paper discussesin detail the whole body reaction time tester in various parts of the structure andfunction of．In addition the paper also offers the data analysis software，introduces thedata processinganalysis software realized functions．Through the development of systemic reaction time tester，and the prototype test，get the following conclusions：1．Through the reading of books，literature understanding and reaction time testerresearch and development related to domestic and foreign development situation andtrend of development，design for total body reaction time tester design conception，andthe“total body reaction time tester”each part of the design scheme is analyzed，make“reaction time tester”prototype． 2．Experiments on the prototype verification，design research and development ofbody reaction time tester has good safety，easy operation；at the same time have verystrong stability and accuracy．3．According to the design concept developed“reaction time tester”prototype，which allows the determination of range from a small muscle groups to participate inthe movement expanded to a large muscle groups to participate in the sports ofdetermination of total body reaction time instrument；test data than the existinginstrument test data are more accurate and more detailed；at the same time the hosttesting system can be connected to the Excel，to facilitate the subsequent use andpopularization．...
