Design and Implementation of “Angel” Empty Nest Elderly Guardian System

In view of the fact that the empty nest elderly can not be treated in time, a health management guardian system based on smart devices is designed. The system relies on the smart bracelet and App to carry out real-time monitoring of the elderly's health, so as to achieve the purpose of controlling the elderly's physical status and timely emergency treatment. The system is divided into three parts: acquisition smart bracelet, cloud server and guardian App. The guardian App includes the children's end and the elderly end, both of which are carried out at the same time to protect the healthy life of the elderly. The system can be connected with the community medical center, so the elderly can call for help at the first time in case of an accident, whether at home or outside. The method in the paper solves the health problems of empty nest elderly, and has certain novelty and practical value.
