Ultrasonic phased array detection imaging system

Abstract

The invention provides an ultrasonic phased array detection imaging system, comprising a phased array ultrasonic probe, a transceiver circuit, a signal processing module, a main control module and a human-computer interaction module. The phased array ultrasonic probe is connected to the signal processing module through the transceiver circuit, the signal processing module is connected to the maincontrol module, and the main control module is connected to the human-computer interaction module. The signal processing module converts detection control information of the main control module into an electric pulse control signal, controls a transmitting circuit of the transceiver circuit, and then controls the ultrasonic array probe to excite a corresponding sound beam to an object to be inspected. The ultrasonic beam is reflected by the internal defect of the object, after a detection echo signal is detected by a receiving circuit, the collected detection echo signal is processed to obtaindetection echo data, and the detection echo data is transmitted back to the main control module. The system can flexibly adjust the scanning coverage by detecting the configuration of detection parameters, the defect parts are detected, and the detection speed and accuracy are ensured.

Description

technical field [0001] The invention relates to an ultrasonic phased array detection and imaging system, which is a non-destructive flaw detection device for detecting cracks, corrosion and other damages on industrial sites, mechanical parts, oil and gas pipelines and other facilities to evaluate their safety status. Background technique [0002] In the modern industrial field, non-destructive testing (NDT) technology is an indispensable part. Various aspects such as product design, finished product inspection, and performance evaluation of service equipment in the industrial production process require the support of corresponding non-destructive testing technology. Mechanical products that have undergone damage testing can increase in value by 5%, products such as national defense and atomic energy can increase in value by 12-18%, and rockets can even reach 20%. It can be seen that the economic benefits brought by non-destructive testing technology are extraordinary. [0...
