This article introduces a multi-functional crutch monitoring system designed with STM32F103C8T6 as the main control chip. This smart crutch monitoring system incorporates a global positioning function, allowing family members to install an application APP on their mobile phones to view the location of the user in real-time, thereby reducing the probability of the elderly getting lost. The crutch also boasts a fall detection feature. When the user falls, it will broadcast a voice message seeking help from passersby, send an SMS alert to the bound mobile phone, and display a reminder window on the APP. Furthermore, this multi-functional crutch monitoring system incorporates Road detection Capability for special locations such as zebra crossings and puddles, informing seniors of the road conditions ahead through voice broadcasts. Additionally, the smart crutch is equipped with functions to monitor heart rate and blood oxygen levels, as well as a one-button broadcast of the current time and a night light illumination feature. Experimental test results demonstrate that this multi-functional crutch monitoring system possesses extensive application prospects and value.
