【 摘 要 】
A method of bathroom fall detection using 20 kHz ultrasound is proposed and tested in bathroom environment.The fall can cause weight loss and increase the velocity of the body movement,resulting in Doppler effect and the shift of the reflected ultrasonic frequency.Based on this frequency shift we can decide whether a person is fall and take relevant measures,so as to protect people's health and safety under the premise of protecting privacy combined with the characteristics of the bathroom,and this method lays a good foundation for the development of intelligent medicine.
