Problems solved by technology

[0004] The traditional ultrasonic detection method is to collect all the data received each time and then transmit them to the data processing unit for processing. If the data of the workpiece to be detected is too large, it will inevitably affect the speed of the data processing unit, and the requirements for hardware will be higher. Real-time detection will be a big obstacle
In addition, traditional ultrasonic testing is generally centralized in structure, and data collection is relatively slow

Embodiment Construction

[0037] This application transmits the data with differences to the cloud and replaces the data with differences, so that the amount of uploaded data will be greatly reduced; in addition, this application puts the data processing method on the cloud to replace the traditional The local computer performs full-focus reconstruction and intelligent calculation analysis, which is not affected by local memory and various hardware, reduces dependence on hardware, and speeds up processing.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by perso...

Abstract

The invention discloses an ultrasonic detection method and device. The method comprises the steps of acquiring a first detection signal after ultrasonic detection; storing the data of the first detection signal locally; transmitting the data to a cloud for storage, and taking the data stored locally and at the cloud as initial data; acquiring a second detection signal after ultrasonic detection again; and comparing the second detection signal with a locally stored first detection signal, if there is a difference, transmitting the difference part to the cloud, and replacing the difference partin the initial data stored in the cloud. According to the invention, only different data are uploaded to the cloud for corresponding analysis; the data volume is reduced to a great extent; and the data state of the cloud is updated in time after the data are replaced with the data stored in the cloud, so that the detection efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of ultrasonic testing, in particular to an ultrasonic testing method and device. Background technique [0002] Ultrasonic testing technology refers to a non-destructive testing method that uses ultrasonic waves to inspect internal defects of metal components. Use the transmitting probe to transmit ultrasonic waves to the surface of the component through the coupling agent. When the ultrasonic wave propagates inside the component, different interfaces will have different reflection signals. By using the time difference of different reflected signals transmitted to the probe, defects inside the component can be detected. According to the height and position of the echo signal displayed on the oscilloscope, the size, position and general nature of the object can be judged. [0003] The traditional centralized ultrasonic detection method has slow response speed, low efficiency, and a large amount of ...
