Design And Implementation Of Intelligent Walking Stick Based On Onenet Internet Of Things Development Platform

In view of the fact that most of the crutches on the market have a single function, they are not convenient for the elderly and blind people to go out and very expensive. In this design, the gyroscope accelerometer module, ultrasonic module, SIM868 module, voice module and so on are controlled by STM32F103 microcontroller, which realizes the detection of obstacles ahead, crutches quickly drop the ground alarm, crutch voice prompt and other basic functions. The APP of mobile phone with hardware is written to the family of crutches, which can update the user's position, security and other information in real time. Therefore, the design not only realizes many key functions, but also increases the exchange of information between users and their families, making it more secure for users to go out alone and the families more assured.
