基于单片机的倒车雷达系统设计
资料介绍
利用超声波传输中时间与距离关系,采用单片机进行控制并进行数据分析及处理,设计出一款能精确测量出两点之间距离的超声波障碍物检测系统。系统主要由超声波电路、单片机控制电路、按键电路及LED显示电路构成。该系统通过超声波发射和接收电路,对系统装置进行了测试,采集安全距离,距离过近时系统会发出声光警报提示操作者做出相应动作。通过消除盲区,提高了测距精确度。此系统具有易控制、工作可靠及测量精度高等优点,可实时进行车距检测。
In this paper,applying the time-distance relationship in ultrasonic transmission,using single-chip microcomputer control and data processing,an ultrasonic obstacle detection system which can accurately measure the distance between two points is designed,which mainly consists of ultrasonic circuit,single chip control circuit,key circuit and LED display circuit.Through ultrasonic transmitting and receiving circuit,the system was tested,and the sound distance was registered.When the distance was too small,Light alarm was issued to the operator to make corresponding actions.The system improves accuracy by eliminating the blind area.This system is easy to control,reliable and highly precise,and can make practical vehicle distance tests.
