摘要
传统自行车缺少灯光指示、环境感知等设备,这为骑行者带来了极大的安全风险和隐患.为此,文中设计了一种多传感器骑行安全辅助系统,该系统以STM32微处理器为主控芯片,以激光雷达、超声波传感器、姿态传感器、霍尔传感器、GPS与通讯模块、LED点阵屏为外围电路,实时感知车辆环境与周边车况,为骑行者提供辅助照明、转向指示、自动鸣笛、碰撞警告、实时定位、危险报警等安全辅助功能.经安装与测试,该系统可提供最大7m的探测距离,低响应延迟,最大25km/h的速度检测,较大提升了骑行者的人身安全.
Abstract
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.
