| Abstract: | Aiming at problems like short coverage of traditional ultrasonic ranging system, put forward a wide-range ultrasonic ranging systems. In order to increase transducer's emissive power, design a new ultrasonic transducer drive circuit, and apply impedance matching on transducer, while adopt Labview software to collect and process echo signals. Experiment result show the range of ultrasonic measuring system is about 32 meters. |
