摘要
本文研制了一种基于虚拟仪器的超声波检测系统。采用TI公司的TMS320C5402DSP处理器,设计了超声波检测系统的硬件电路,提出了超声检测信号的处理算法,并编写其软件;采用NI公司的虚拟仪器开发平台LabVIEW开发设计超声检测系统上位机各软件功能模块。该系统能够实现被测物体回波信号的采集、显示、存储及处理等功能,在碳素钢锻件、焊缝、复合钢板等的缺陷检测上具有应用价值。
In this paper an ultrasonic detecting system based on Virtual Instrument is presented. Firstly, this paper designed the hard- ware part of the detecting system using TMS320C5402DSP. Secondly, the paper put forward an echo signal processing algorithm and designed the software part. The upper software of the system is designed with LabVIEW. The software is designed for flaw detection, data storage and analysis of data and waveforms. The detecting system can be used for the testing of welding seams and rail weld.
