碩士 === 逢甲大學 === 自動控制工程所 === 95 === The goal of the project is to develop a platform which could measure the balance center of gravity (COG) of the human body, and it will be able to diagnose if the patient has diseases arose from balanced barrier or the degree of the ability for adjusting the balance by himself. First, we use ANSYS tool based on finite element method to execute all stress and strain analysis of the platform. Using the results of simulation we can manufacture a measurable platform actually. Since the variation COG of the human body will cause different strain on the stem, we would attach four strain gages to detect the COG signal. Finally, we complete the signals processing and transmit it to the computer with serial communication interface-RS232, the real time trajectory the COG could be shown. In system software several statistics information about the dynamic trajectory of the COG will be calculate such as; average radius, swept area, the variance, the correlation between X and Y direction, etc. On the other hand, the measurement system combines visual feedback control, it can diagnose the vision, proprioception and vestibular system diseases and transmit the data to the profession database. The profession database will make a diagnosis of a patient’s disease and provide a optimum suggest.
