Design and implementation of an elderly tracker system

Abstract

With the science development, human longevity becomes longer, but it brings about an aging population for this reason. Thus, it is extremely important to nurse and care for the aged. When the aged go out without the companion of their children, they may have no way to call for help, if there is any fortuitous event. In this situation, it is urgent to have a kind of product, which can inform children of the aged in time about the current location information of the aged and physical conditions. In the paper, a solution of an elderly tracker (hereinafter referred to as the terminal) is introduced to acquire the current location information of the aged through GSM/GPRS functional module SIM900 and GPS functional module SIM28. Moreover, SOS key is set up to inform their children by dialing an emergency call. BP neural network algorithm is applied to analyze a frequented place of the aged by using the cloud server and to remind them by playing the warning beep at the accident prone location. In addition, the frequented location information of the aged can be provided for elderly service agencies, so as to help these agencies to provide service quality. The solution proposed in the paper had the biggest drifting for 5m by testing actually. Average consumption is about 2.8mA and it is enough to satisfy application demands.
