摘要
采用ARM Cortex-M3内核微处理器STM32F103作为计算控制单元,采用模块化设计实现报警、转弯障碍检测、危险区域投射与内轮差面积计算等功能.通过采集速度和转弯角度等数据,并利用内轮差算法计算出内轮差大小,再由投射系统向地面投射出危险区域.货车在转弯时,还能探测到危险区域内的人或其他障碍物,并通过声音报警提示,较传统报警装置报警更精确.
A truck turning-alarm system based on STM32 F103 is designed in this paper. ARM CortexM3 kernel microprocessor STM32 F103 is adopted as CPU. This system adopts module design method and realizes some functions such as alarming,obstacle turn-detecting,dangerous area projecting,inner wheel difference area calculating. By collecting the data about speed,turning angle and so on and using the inner wheel difference algorithm to calculate the data of speed and turning-angel,the project system can project red light to the ground to draw out the dangerous area. When the truck makes a turn,this system can detect people and other obstacles in the dangerous area,and then make alarming sound. This system is more accurate than the tradition alarming system.
