Old people fall detection and alarm system based on 3D (3-dimensional) accelerometer and gyroscope

The invention relates to an old people fall detection and alarm system based on a 3D (3-dimensional) accelerometer and a gyroscope, belonging to the field of electronic information. The old people fall detection and alarm system is characterized in that a human body motion activity sensing module which is integrated with the 3D accelerometer, the gyroscope, a bluetooth chip and a microprocessor is embedded into a vest which is put on by old people, the 3D acceleration and the angular speed data of the activities of the old people are acquired in real time, the data of the activities is transmitted to a smart mobile phone in which fall detection software runs through bluetooth; the fall detection software automatically calculates the corresponding resultant acceleration alpha and the corresponding deflection angle theta according to the received activity data; and when the resultant acceleration alpha is larger than a resultant acceleration threshold alpha T and the deflection angle theta is larger than a deflection angle threshold theta T, a fall which occurs is judged, an alarm is given out by calling a designated contact person or transmitting a short message containing the position of the old people to the designated contact person through the mobile phone. The resultant acceleration threshold alpha T and the deflection angle threshold theta T used by the fall detection software are obtained by adopting a Bayesian algorithm. The fall detection and alarm system has the characteristics that the detection accuracy is high and the system is convenient for the old people to use.
