ABSTRACT: Today’s riding equipment is mostly for professional riding users, with single function and high price. According to this situation, this paper intends to design an intelligent riding system based on STM32, which can provide key riding data for riders at a reasonable price. To a certain extent, it can ensure the safety of riders on the way, and achieve the purpose of healthy riding and green travel. The design is mainly composed of four parts, namely the main control part, detection part, display part and alarm part. Firstly, the STM32F103ZE microcontroller is used as the main control core, and the heart rate sensor, blood oxygen sensor and Hall sensor are expanded to realize the data acquisition and display of the rider’s heart rate, blood oxygen, speed and mileage. Secondly, the intelligent riding instrument will compare the real-time collected data with the preset threshold, and start the sound light prompt and voice alarm when a certain data is close to or beyond the preset range. In addition, this design realizes automatic lighting in the dark through photosensitive sensor. Finally, this design adopts solar power supply mode; the intelligent riding instrument designed in this paper can measure the riding speed, mileage, heart rate and blood oxygen of the rider, and is easy to operate.
