The invention discloses an STM32F407-based intelligent
walking stick system and a control method, which are used for solving the problems of single function, high
false alarm rate and insufficient
data security of the traditional
walking stick. The
system integrates a posture detection module, a
heart rate and blood
oxygen monitoring module and an environment sensing module, constructs a user
health risk pre-judgment model through multi-
modal data fusion, realizes a three-level adaptive alarm mechanism in combination with a dynamic decision
algorithm, and triggers acousto-optic warning, cloud communication and emergency contact linkage according to risk levels. The
payment and
data transmission reliability is guaranteed by adopting a physically isolated security architecture and a national secret
encryption technology; the
dynamic power management system optimizes
energy consumption distribution according to scene requirements, and the endurance of equipment is remarkably prolonged. According to the system, the monitoring accuracy is improved through a closed-loop
protection system (
risk identification-
adaptive response-energy optimization),
bus payment and smart
home control are supported, the system has the characteristics of low
false alarm rate, high environmental adaptability and low
power consumption, and a safe and convenient life auxiliary solution is provided for old users.
