碩士 === 逢甲大學 === 電機工程學系 === 107 === This thesis proposes to analyze and process the signals transmitted in real time, such as using the radar system to measure the distance , speed of object measurement, etc., and then use the human-machine interface (LabVIEW) to filter the signals and display them on the computer screen. Users can get their relevant data, which uses the Arduino's signal to perform preliminary analog-to-digital converster, and uses the relevant Bluetooth module to transfer to LabVIEW in the computer. The signals display in time domain and frequency domain to show different frequency. The signal that has been processed by the analog-to-digital converster is displayed with different frequency signals in the time domain and the frequency domain, respectively, and in this paper, the human life signs are used as the measurement target, because the human body will still produce the fluctuation of breathing and heartbeat even when it is at rest, and the measuring signal will transmitt the measurement signal through the Bluetooth of the Arduino. The wireless transmission method can reach and display at a certain distance with Bluetooth. Finally, the results of different materials and spectrum versus time are presented to prove the stability of the measurement capability and measurement capability of this design architecture.
