碩士 === 國立彰化師範大學 === 機電工程學系所 === 105 === Advances in technology and the use of yearly progress on the development of many traditional measurement tools and methods gradually been newly developed non-contact measurement equipment and technology replaced, while the panel industry cut glass manufacturing process using the cutter wheel determines cutting section flatness and glass strength, the use of vibration to detect damage to the cutter wheel to predict the state can reduce costs and improve productivity of high value. Most industrial piezoelectric accelerometer to measure the vibration, the main use of certain specific substances, such as quartz crystal piezoelectric effect to generate a voltage proportional to the amount of vibration or pressure at the time of the accelerometer to feel the shock of change Measure. With industrial development and progress, the daily life of many products: smartphones, tablet computers and interactive video game built linear accelerometer (G-sensor), the use of measuring small changes in physical quantity obtained inclination angle means for sensing orientation , the angle and acceleration. In this experiment, linear accelerometer (G-sensor) to establish a low-cost, small size, easy monitoring systems for the purpose on the planning and design of hardware and software with LabView FIG arduino control analysis software, has a preliminary measurement data validation. In three different degrees of damage to the cutter wheel linear accelerometer (G-sensor) feedback of the peak, reached the cutter wheel impaired judgment based linear accelerometer (G-sensor), although in the high-frequency signal are received its limitations exist, this experiment for a small amount of vibration Jie excellent results, in particular, can simultaneously measure three axial vibration signals can be further more additional axial force caused by the signal interpretation, reach detection prevention targets.
