| Title | The Study and Application of Distance-Measurement System Based on Ultrasonic Wave |
| Abstract | This paper primarily investigates a kind of ultrasonic distance measurement device based on microprocessor.This device can measure certain distance with reflected wave on condition that the speed of transmitting wave is fixed.It generally specifies the theoretical foundation of the device,introduces the software and hardware design of the device and correlative experiments.The design of the distance measurement is targeted on high precision and little blind area.Then it proposes the whole structure of the system by introducing the function of ultrasonic distance meter and presenting the theory and characters of ultrasonic sensor.And then the transmission,receiver,detection,display scheme of this distance meter system is brought out.At the same time,a number of main technical parameters are discussed.Moreover,the AT89S52 microcontroller is employed in this system to achieve the function of collecting,processing,and displaying of data. In order to raise the device’s precision,it takes measures such as temperature compensation and so on.And the application of control circuit decreases the device’s blind area.And it composes several experiments,and analyzes the experimental results. |
