Design of an auxiliary system for cycling safety based on multi-sensor
The traditional bicycles lack lighting equipment and environment sensor,which bring great safety risks and hidden dangers to cyclists.Therefore,we design a cycling auxiliary and safety inspection system using STM32 microprocessor as the main control chip,and the laser radar,ultrasonic sensor,attitude sen-sor,Hall sensor,GPS and communication module and LED dot matrix screen serving as the peripheral cir-cuit,which could offer real-time detection of cars and their surrounding environment.Besides,it can also provide supplementary lighting,direction indication,automatic honking,collision warning,real-time posi-tioning,danger alalrming and other safety auxiliary functions for riders.After actual installation and testing,the system can provide a maximum detection distance of 7m,low response latency and speed detection up to 25km/h,greatly improving the personal safety of cyclists.
