Abstract

The invention discloses an automatic detection system for an ultrasonic transducer and a detection method, and is used for analyzing the characteristics of the transmitting wave and the echo of the ultrasonic transducer. The system comprises a wave reflection device, an ultrasonic transducer, a wave transmission device, an oscillographic device and a computer, wherein the wave reflection device forms the echo through the reflection of a transmission wave; the ultrasonic transducer converts an input transmission wave electric signal into a transmission wave, the transmission wave is emitted, and the received echo is converted into an echo electric signal, and the echo electric signal is output; the wave transmission device sends the transmission wave electric signal to the ultrasonic transducer, and receives the echo electric signal from the ultrasonic transducer; the oscillographic device displays the transmission wave electric signal and the echo electric signal in the same frame of oscillogram through receiving the transmission wave electric signal and the echo electric signal of the wave transmission device; and the computer reads oscillogram data from the oscillographic deviceand carries out ultrasonic transducer characteristic analysis. The system has the advantages of high detection speed, no human factor interference and high accuracy, and the detection speed of the ultrasonic transducer is improved.

Description

technical field [0001] The invention relates to the technical field of transducer detection equipment, in particular to an automatic detection system and detection method for an ultrasonic transducer. Background technique [0002] Ultrasonic transducers are devices that use the piezoelectric effect of ceramics to convert mechanical vibrations generated by ultrasonic waves into electrical signals or generate mechanical vibrations under the drive of an electric field to emit ultrasonic waves. In detection applications, ultrasonic transducers are used in pairs, one One is used for transmission and one is used for reception. In order to ensure the validity of the ultrasonic transducer detection data, it is necessary to ensure that the characteristics of the transmitted wave and the echo of the paired transducers match. [0003] The detection and judgment of ultrasonic transducers in the prior art are all manual operations, the judgment is inaccurate, and the efficiency is low, w...
