Design of Self-Storage Energy and Anti-lost Device Based on Dual Distance Measurement and Beidou Positioning

In recent years, the proportion of vulnerable groups such as children and the elderly has been increasing year by year. Wearable devices on the market are mostly used for location finding after the event, and the battery life of the devices is weak, which is not conducive to real-time tracking of lost people. In order to fundamentally solve the phenomenon of losing vulnerable people, this paper proposes a short- range ranging method using infrared and ultrasonic waves, using Beidou positioning real-time tracking technology and an anti-lost device using self- storage mechanical power generation to solve the problem. The problem of weak endurance and improvement of real-time tracking efficiency.
