Thanks to the network communication and high portability exhibited by the smartphone, this thesis is aimed to integrate the power signal detection capability as well as image monitoring into a smartphone, thereby anticipating to achieve the power quality expectation of modern industry. In this proposed system, the embedded program language was utilized along with the wavelet transform and S-transform for the power signal detection. Meanwhile, the virtual instrumentation software was also employed to facilitate the image monitoring, acquisition and storage in order to provide the forewarning capability. To validate the feasibility, this method was also tested through signals acquired from several power quality events including voltage interruptions, sags and swells. Besides, the monitoring interface developed for the image visualization was also tested. By those test results presented, they are deemed useful to confirm the feasibility of the proposed method.
