In this paper, an intelligent security monitoring system for the elderly living alone is designed and implemented to improve the efficiency of fall detection and emergency response for the elderly. The system uses STM32F407ZGT6 microcontroller as the core, combined with ICM20608 attitude detection module, ultrasonic sensor, GPS, SIM800C and 4G communication module to realize multi-modal data fusion and real-time monitoring. Through the fall recognition algorithm, Posture Analysis Method and heart rate and blood oxygen monitoring technology, the detection accuracy is improved. The system supports 4G and SMS phone dual-mode communication to ensure stable transmission in complex environments, and realizes the function of elderly location positioning and real-time viewing of elderly status through small programs. The test results show that the system has good real-time performance, accuracy and stability. This study provides an effective solution for the safety monitoring of the elderly living alone.
