中文摘要	针对传统涡流检测仪器硬件复杂、成本较高的缺点,采用虚拟仪器技术,研制了一套基于LabVIEW的涡流无损检测系统。系统由涡流检测硬件电路、上位计算机、数据采集卡以及相关软件组成。重点介绍了硬件电路中的激励源、自动平衡电路和相敏检波模块的设计。系统完成后,对圆管管壁通孔和钢条裂纹进行了检测试验。检测结果表明系统具备良好的检测性能。; Directing against the disadvantage of the complicated hardware and high cost of traditional eddy current testing instrument,a LabVIEW based eddy current testing system was developed.The system was composed of hardware circuit,computer,data acquisition card and relative software.The design of the carrier frequency generator,auto-balance circuit and the phase-sensitive detector was introduced in detail.Testing experiments were done using the system,and the results showed that the system had good testing capability.
