老年人跌倒检测与报警系统：基于Android的智能监测解决方案

The document "Fall Detection - Fall Alarm - Android.docx" addresses the critical issue of the increasing incidence of fall-related injuries, hospitalization, and mortality among the elderly population, leading to a significant social and economic burden. In response to this challenge, the document proposes the development of a fall detection and alarm system that aims to monitor the activities of the elderly and provide rapid assistance in the event of a fall, thereby reducing the impact of fall-related injuries and medical expenses. Drawing on a comparative analysis of foreign research on fall detection technologies, the document presents a novel approach based on the use of triaxial acceleration sensors and gyroscopes to detect falls and trigger timely alarms. Real-time data on acceleration and angular velocity generated during the elderly person's daily activities is collected by the sensors and transmitted to an Android phone via Bluetooth. The accompanying software on the phone processes and analyzes the received data to determine the elderly person's movement status and triggers an alarm upon detecting a fall. The alarm prompts the elderly person to respond, and in the absence of a response within 5 seconds, the system activates a pre-set alarm notification method, such as sending a text message or making a phone call to predefined contacts, along with the location information of the fall. Additionally, the system allows the elderly person to independently raise an alarm in the case of feeling unwell, enhancing overall safety and security. In conclusion, this innovative fall detection and alarm system presents a promising solution for addressing the increasing challenges posed by fall-related incidents among the elderly, with the potential to have a significant positive impact on their health and well-being.
