Design and Application of Automatic Imaging System for Ultrasonic Phased Array Nondestructive Inspection

利用Microsoft.net作为开发平台,完成超声相控阵无损检测自动成像系统的开发和设计。该系统可以通过USB接口控制相控阵电路硬件系统阵元发射,完成数据实时采集和数据实时成像任务。系统同时支持A扫、B扫和S扫等多种超声相控阵扫查方式,同时成像参数、成像方式可以通过界面参数进行选择,并能实现图像放大缩小、光标定位、图像标尺标定和实时系统参数校正,采集到的数据可根据不同的扫查方式,实现3种格式的文件存储。通过自主开发超声线控阵无损检测自动成像系统节约了成本并拥有独立的知识产权。该系统方便灵活,加深了对超声相控阵信号成像的直观理解,有助于推动相控超声技术在无损检测中的应用。该系统也可以植入便携式设备,方便检测人员的使用。

An automatic imaging system for ultrasonic phased array nondestructive inspection is designed based on the Microsoft.net,which can control the ultrasonic phased array to impulse signal by USB interface and accomplish the real-time imaging by real-time data acquisition.The system supports multiple phased scan methods including A-scan,B-scan and S-scan.Meanwhile,the imaging components and mode can be selected on the software interface.The system can also achieve image zoom,cursor positioning and image digital scale.The parameters can be calibrated and there are three file storage formats for the real-time data supported by the system.The system helps better understand the ultrasonic phased array signal imaging and plays a big supporting role in the experiment and promotes the ultrasonic phased array technology in the non-destructive testing application.It can be implanted in a portable device to facilitate inspectors.
