碩士 === 國立高雄大學 === 電機工程學系--先進電子構裝技術產業研發碩士專班 === 105 === In this thesis we demonstrate an AC/DC power measurement system based on the fiber Bragg grating sensing technique for the development of smart house safety monitoring. A fiber Bragg grating DC voltage transducer constructed by the piezo-electric tube is able to achieve DC voltage measurement within 0 V-150 V ranges with an accuracy of ±10 V, and a fiber Bragg grating AC voltage transducer constructed by the electro-magnetic vibrator is able to achieve AC voltage measurement within 0 V-150 V RMS with accuracy of ±5 V. In addi-tion, a theoretical model of the fiber grating AC transducer base on the driven oscillation sys-tem was developed to analyze key parameters of factors of the fiber grating AC voltage transducer such as mass, spring constant and damping factor.
