Application of network data transmission in ultrasonic automatic inspection system

摘要

An ultrasonic automatic detection system, which had the characteristic of transmitting data of ultrasonic inspection signal based on the Ethernet network, was presented in this paper. The system was composed of the detection computer and the operation computer. The detection computer was placed near the workpiece, gathering the ultrasonic probe signal and directly transforming the analog signal into the digital signal in the inspection process. Then the digital signal was transmitted to the operation computer through the network. The operation computer completed the ultrasonic digital signal analysis, processing, display and data storage. This system has high detection efficiency and strong noise proof capability in the work field. This paper also introduced the application of the network transmission method in the multi-channel automatic detection system, such as the entire steel pipe body detection and the axle radial direction flaw detection.
