Research And Implementation Of Speed Perception Tester Based On Wireless Communication Technology

Speed perception reflects moving characteristics of object in human brain. It is also the perception about position and velocity changes of object or portion. Speed perception indicates the distinctness of sense for velocity for everybody. It's a crucial technical criterion in every working, practice and physical training sports. Therefore, possessing well and truly the ability of estimating speed is essential and indispensable.The speed percetion tester applys for measuring capability of speed perceptionn.The apparatus is a psychological tests instrument. It is used to calculate the response rate of speed.And it is suit the tests and experiments of athletes and drivers' predicting for speed of object.This dissertation is based on sports psychology and experimental psychology. After investigating the development and application of speed perception tester of native and abroad, this thesis designs a speed perception test system, which based on VB2008 and MSP430F135 with ultralow-power microcontroller.This system is in possession of lower cost, ultralow-power, and scientific, simple and convenient test measures. And the main research on this thesis is as follows:Firstly, this dissertation analyses psychological theory, makes a survey on applied condition and research achievement of speed perception test system at native and abroad. Then it summarizes and analyses the existing speed perception test system.It illuminates designing a speed perception test system is significant and essential.And it introduces the wireless communication technique, which is used in my thesis.Besides, it introduces detailedly the overall design ways and means about this test and control system of speed perception which based on VB2008 and MSP430.Sencondly, this thesis expatiates on circuit design of arming light port, reaction key port, LCD port, clock port, luminous tube port and communication port. It also introduces the technique of software about them.This controller take charge of regulating the speed of light, managing IRQ of response button, and giving the result according to the formula.Thirdly,it presents monitor interface design based on VB2008 in detail.Gives mainly the communication method and program with controller using the SerialPort wedget paticularly,introduces the foundation and connection of the Access database, the design method of data table, the design technique of data export into EXCEL and data report print.Finally, this thesis gives the software and hardware debug process of the speed perception test system based on IAR EW430 3.10A debug environment. Stress the data transferring and processing method between MSP430 controller and VB2008. And the speed perception test system match the design requirement through the simulate debug and test running in Lab.
