摘要
主要设计了以AT89C51单片机为核心的一种低成本、高精度、微型化,并有数字显示和声光报警功能的智能防撞报警系统。包含有智能防撞报警系统,包括正向防撞预警系统、自动泊车系统和倒车防撞雷达系统。该系统利用超声波进行测距,性能可靠,增强了驾驶的安全性,同时也提高了泊车和倒车时的安全与效率。
This paper mainly designs a low cost, high-accuracy, micro-miniaturization, and digital display and acousto-optic alarm features of the vehicle intelligent anti-collision warning system based on MCU AT89C51. The vehicle intelligent anticollision warning system includes forward anti-collision warning system, auto parking systems and reversing anticollision radar system. It mainly develops on the basis of ultrasonic distance measurement, its performance is reliable,thus the driving safety is greatly improved and the parking and reversing security and efficiency enhance enormously.
