In order to satisfy the requirements of the elderly care,and lessen the physical and psychological hurt caused by falling,the authors presented a fall detection system using a tri-axis accelerometer.The study idea was based on the attitude estimation using tri-axis accelerometer for the judgment of falling detection.In addition,considering the impact from the noise and the high accuracy of the falling detection system,the Kalman filtering algorithm was used to improve the system's reliability.The experimental results show that the system can alarm 100% when the human body is falling fore-and-aft,laterally and rapidly rising after falling,and can achieve the detection level of normal human falling.
