摘要
随着人们生活水平的日益提高,汽车数量也与日俱增,因此汽车的行驶安全就显得尤为重要。介绍一种基于单片机SB5027的汽车防碰撞报警系统,它能自动检测行进中汽车前后方障碍物的距离,当达到安全极限距离时,发出声光报警,提示驾驶员进行相应的操作。给出该报警系统的软硬件设计,实践证明该系统有效且准确。
With rising of living standard,the number of cars increased every day, so cars driving safety is particularly important. The system of automobile anti- collision alarming system based on single chip SB5027 is introduced,it can auto detect distance frontage and rear fraise,when reach critical security distance,alarming of sound and light are given,the system hardware composition and software project are showed, Experiment results prove validity and veracity.
