摘要
针对一般的超声测距系统作用距离都不大的问题,设计一种大量程的超声波测距系统。为增大换能器的发射功率,专门设计一种新型的超声换能器驱动电路,对换能器采用阻抗匹配技术。采用Labview软件对回波信号进行实时采集和处理。实验表明,该超声波测距系统的量程可达到32m。
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.
