摘要
该设计以AT89C51型单片机为核心,采用四路超声波传感器进行测距,并由液晶屏将四个方位的距离显示。当汽车四路所测得的值达到危险值时,系统将通过蜂鸣器发出警报。该系统具有语音提示功能,每过3s钟读取一次四个方向的距离值,对驾驶员进行安全提醒。
This design uses the AT89C51microcontroller as the main core of the system.In the hardware design part,four-way ultrasonic sensors are used to measure the distance.The distances of the four bearings are displayed through the liquid crystal display.When the measured distance reaches the dangerous value,the driver will be alerted through the buzzer.The system has a voice prompt function,and the distance of four directions will be automatically read every3seconds,providing safety warning for drivers.
