| Abstract: | The ultrasonic distance measuring system composes of signal generate and adjust model, temperature changing measure model, amplified model, monitor model, alarm model and so on. 40kHz frequency signal is adjusted with 0.2 ms signal generate circuit, 40 RS/UT180 ultrasonic sensor is driven with double working model to detect the returning wave, amplify LM567 input phase-locked loop to monitor electric circuit and send detected signal into the controller. And the experimenting data was fitted and validated by least square method. |
