Abstract:


Among the advanced countries, especially in Japan, we are facing on the decreasing birthrate and aging population ahead of the world. In recent, population of single-living elder, and elderly people have been taking care by same-aged person, have been actualized. Unfortunately, the population of caregivers is decreasing according to year. In this situation, the Elderly Person Watching System has been focused on. Especially, Robotics, Internet of Things, and Artificial Intelligence technology have been having high affinity with this system. In this study, a development for watching system based on home appliance will be focused on. In detail, in this paper, the load current of each home appliances will be focused on. In the proposed method, a clamp AC current sensor has been mounted on ac cable of a home appliance to obtain its load current. Moreover, to analyze the frequency characteristics of the obtained home appliance’s load current, FFT has been executed. From the verification experiment, the proposed method showed that has been acquired the result of utilization status of the home appliances that based on FFT.
