基于嵌入式Linux+QT的管道超声导波检测系统图形用户界面设计

Design of Graphical User Interface for Pipeline Detection System of Ultrasonic Guided Wave Based on Embedded Linux+QT

超声导波检测技术通过单端激励方式,可以实现对管道的长距离、大范围检测,被广泛用于工业无损检测和结构健康监测领域。针对目前导波检测系统图形用户界面跨平台和可移植性差的问题,进行了基于嵌入式Linux+QT的管道超声导波检测系统图形用户界面的设计和开发。实验结果表明,该图形用户界面具有可操作性强、运行可靠和界面友好的特点,进一步通过交叉编译工具链可实现对跨平台应用的需要。

Ultrasonic guided wave technique detects pipelines in a large-range and long-distance by the method of single-ended excitation,and is widely used in fields of Non-Destructive Testing（NDT） and Structural Health Monitoring（SHM）. Aiming at the problem of the poor cross-platform-ability and portability of graphical user interface（GUI）of current guided-wave detection systems,this paper presents the design and development of the GUI of pipeline detection system of ultrasonic guided wave based on embedded Linux and QT. The experimental results show that the GUI has a series of characteristics such as high operability,reliability and friendly interface.It can be compiled for the cross-platform application by cross compiler tool chain.
