碩士 === 淡江大學 === 電機工程學系碩士在職專班 === 99 === In recent years, due to the rapid development of information society, it is accompanied by the increase in obesity and chronic disease population, so people have gradually paid attention to this issue. In the weight loss process, in addition to diet control, also need moderate exercise. But in the current market, there is not portable equipment could record our sports information. Based on the above requirements, this thesis is trying to design a multi-function micro-control system with built in three-axis acceleration sensors and three-axis gyro sensors. In order to achieve a full range of purposes, we could put this inertial sensing module on the waist, the built-in sensor will detects the dynamic information from body automatically, After the calculation, we could know the amount of calories consumed . My study found that, in order to more accurately estimate the calories consumed, we must get the following information during exercise: movement patterns (to apply for the metabolic equivalent), exercise intensity (ie, the exercise frequency per unit time), exercise time and Weight. In this study, we use the acceleration sensor to estimate the movement pattern, because the acceleration sensor could present two forces included gravitational acceleration and body movement, and the changes in posture during exercise will indirectly affect the proportion imposed on the sensors by gravitational acceleration and body movement, so we can use this information to determine the type of the movement pattern. Otherwise, using a gyroscope to detect the purpose of exercise intensity is because the output of gyroscopes is zero in the stationary state, and totally not affected by gravitational acceleration. With higher resolution, we take the gyroscope as a good way to determine exercise intensity. In the future, if it could combine with the sports science to design an all day self-health management monitor to support external observation.
