In Japan, the number of elderly people living alone has increased in recent years. Therefore, we propose a safety confirmation system that includes an ultrasonic radar for confirming the safety of elderly people living alone. This system consists of an ultrasonic radar, a power line communication unit, and an information processing communication unit. The safety confirmation method performs the human body detection in the restroom using ultrasonic radar. In addition, the proposed system contains a self-checking function. The effectiveness of the proposed system has been confirmed by the results of a field experiment.
