The Design and Implementation of the Elder Fall Remote Monitoring System in the Smart Home

Based on the analysis of the state of human body falling, this paper designed a kind of fall detection alarming apparatus based on the change of acceleration. The principle is detecting the 3-axis’s acceleration change of sensor caused by change of the body posture when the wearer falls down. When the signal of body falling is detected, the fall detection alarming apparatus emits audible alarm signals. The alarm information will be send to guardian automatically through short message or calling by GPRS module, at the same time, it will be store and send to remote monitoring web page of the smart home through IEEE 802.15.4E wireless way in order to remote alarm notification.
