随着社会经济的发展和交通运输业的不断兴旺,汽车的数量在不断地增加。交通拥挤状况日益严重,撞车事件也经常发生,造成了很多的人身伤亡和经济损失。面对这种情况,设计一种响应快、可靠性高并且比较经济实用的汽车倒车雷达系统就显得非常重要。本文是基于超声波测距的汽车倒车雷达系统的设计,主要是利用超声波的特点和优势,将超声波测距系统和STC89C52单片机结合于一体,设计出一种基于STC89C52单片机的倒车雷达系统。本系统采用软硬件结合的方法,具有模块化和多用化的特点。
With the social and economic development and transportation industry continues to flourish, the number of cars is constantly increasing. Traffic congestion is worsening and crashes frequently occur, resulting in many personal injuries and economic losses. Faced with this situation, the design of a fast response, high reliability and more economical car reversing radar system is very important. This article is based on ultrasonic ranging car reversing radar system design, the main is the use of ultrasonic characteristics and advantages of the ultrasonic ranging system and STC89C52 microcontroller combined to design a STC89C52 microcontroller based on the reversing radar system. The system uses a combination of hardware and software methods, with modular and versatile features.
