在虚拟仪器的开发理念下, 结合目前常规的超声检测方法, 提出了基于虚拟仪器的钢管在线自动超声检测系统。主要从机械设计、电气控制和上位机超声检测仪器三个方面对系统做了简单介绍。该系统的上位机超声检测仪器部分开发周期短、效率高, 软件编程灵活, 可以根据需要随时进行改进, 为方便实现钢管在线自动超声检测图像化结果显示奠定了基础。

The on-line automatic ultrasonic testing(UT) system for steel pipe based on the virtual instrument is proposed through combining the design concept of virtual instrument with the conventional ultrasonic testing method in currently. The detection system was introduced from three aspects: mechanical design, electrical control and ultrasonic testing instrument. The development cycle of the ultrasonic testing instrument is short with high efficiency. The software programming is flexible and can be improved when needed. It has laid the foundation for graphical display of pipe on-line automatic ultrasonic testing.
