| 摘 要： | 超声波测距是一种利用超声共性、电子技术、光电开关组合,完成非接触式距离测量的办法。本设计以STC89C52单片机为主要控制器设计了一个超声波测距仪,通过计算超声发射到接收所用的时间差,再有经过温度补偿的超声波的速度,通过计算就可以得出超声波和障碍物之间的距离。若超出设定的安全距离蜂鸣器将报警。最后将测得的数据交由液晶屏显示。它的测量范围为0.2cm-500cm,测量精度为毫米级别。

| Abstract: | Ultrasonic distance measurement is a method of non-contact distance measurement based on the combination of ultrasonic commonness,electronic technology and photoelectric switch.In this design,an ultrasonic rangefinder is designed with STC89C52 microcontroller as the main controller,The distance between the ultrasonic wave and the obstacle can be obtained by calculating the time difference between ultrasonic wave transmission and reception,and the speed of ultrasonic wave compensated by temperature.If the set safe distance is exceeded,the buzzer will alarm.Finally,the measured data will be sent to the LCD screen for display.Its measuring range is 0.2cm-500cm,and the measurement accuracy is mm grade. |
