STM32-based Anti-fall Smart Vest System for the Elderly

With the increasing trend of population aging in our country, how to take care of the elderly has become the focus of attention from all walks of life. In order to reduce the occurrence of incidents that the elderly did not receive timely assistance due to falling, this article designed a smart vest system with STM32 single-chip microcomputer as the main control chip, which uses ultrasonic sensors to obtain the distance between the elderly and obstacles to realize the anti-collision reminder function. Connect the six-axis acceleration sensor for fall detection and control the ejection of the airbag to complete the fall protection function. At the same time, the alarm information is sent to the target associated mobile phone through the GSM network, and the HTTP communication protocol is used to communicate with the OneNET platform (China Mobile Internet of Things Open Platform) carry out data interaction and realize the function of positioning for help. The system also uses human heart rate sensors and body temperature sensors to collect real-time data on the physiological state of the elderly; this system adds a strong guarantee for the health and safety of the elderly.
