With the progress of science and technology, acoustic measurement tube technology has a broad application prospect in the field of engineering detection, especially in the new infrastructure of smart city and intelligent transportation. The detection of underground pipeline network needs to be carried out without destroying the pipeline to ensure the practicability and safety of the detection. However, traditional methods such as magnetic survey, electromagnetic method and ground penetrating radar have the problems of low accuracy, vulnerability to interference and high cost. Ultrasonic testing has become the preferred method for non-destructive testing due to its high directivity and sensitivity, non-contact, strong anti-interference and penetrating ability. This paper introduces a fully automatic ultrasonic detection device, which can realize the automatic positioning, detection and analysis of the acoustic tube, significantly improve the detection efficiency and accuracy, and reduce the influence of human factors.
