Abstract :
For the health-care needs of the elderly people, a fall detection indoor positioning system based on CC2431 wireless positioning system and SCA3060 tri-axis accelerometer is designed in this paper. CC2431 location engine positioning algorithm is based on the RSSI values. The blind node will collect the RSSI value from both itself and the reference nodes and then locate the fallen elderly people by entering the corresponding parameters of the environment. The tri-axis accelerometer can determine the elderly fall direction and level by collecting X, Y, Z-axis accelerometer. When the acceleration exceeds some threshold, a signal will be sent to the blind node to locate the position and send alerts.
