| Summary: | 碩士 === 中華科技大學 === 機電光工程研究所碩士班 === 102 === This thesis is is to setup the human balance instrument based on Digital Signal Processor (DSP). One is hardware, and the other is software. Hardware are including four sets of load cell sensor for testing platform, amplification circuit ,voltage regulator circuit, DSP(TMS320F2812), and interface transmission line USB100V2. The Software includes 4Channel data acquisition systems in DSP, the center of gravity computation and data display.
We use four sets of load cell to transform weight into voltage signals by using the Instrument Amplifier then connect the output signal of Instrument Amplifier to AD converter in the DSP system. The software processes are divided into two steps. step one, we applies least squares regression analysis to determine the relationship between the weight and the voltage; step two, determining the center of gravity by the method of gravity then transform the statistics into diagrams and indicate the balance situations of subjects in a simple way.
This research contribution are finished the functions to display the point of force application in different situations and the center of gravity. By using these functions, we can apply to sports medicine, balance training of athletes that can be as reference for geriatrics, orthopedics, rehabilitation and other medical aspects.
