Research and implementation of safety alarm for the elderly based on STM32 control

WANG Junwen;School of Software and Applied Science and Technology,Zhengzhou University;  
In today's society,the development of the times makes it difficult for young people to accompany their parents and elders effectively. At the same time,with the aggravation of population aging,more and more elderly people need further social attention. In recent years,the loss of the elderly often happens around the people. In order to reduce the loss rate and ensure the safety of the elderly,besides the efforts of the public security departments and family members,it is more necessary to join the newtechnology. In the era of smart wear becoming more and more popular,this paper designs a stable and safe alarm for the elderly. The main control board of this work is STM32 F103 based on ARMCortex-M3 core,which carries the WiFi module of GSMmodule,and can realize the triple positioning of GPS,WiFi and LBS at the same time. With mobile client software,the guardian can viewthe wearer's historical track and real-time location through the software platform. The electronic fence can be set manually or the safety range can be recommended intelligently according to the user's historical trajectory. With the sensitive inertial sensor MEMS,the information reminder can be sent to the guardian in time to ensure the safety of the elderly when they fall by detecting the frequency of the wearer's walking step frequency vibration.
