蒸汽发生器传热管涡流检测中采集数据的分析，是确保蒸汽发生器在安全工况下运行的必不可少的环节，这必然需要通过相关软件来完成。然而，我国核电行业在这方面的工作仍主要依靠国外的相关软件来完成。为了改变这种现状，对涡流数据分析的相关算法和技术进行了研究并开发了一套蒸汽发生器传热管涡流检测数据分析软件，该软件系统地解决了核电站蒸汽发生器传热管涡流检测中所需的基础功能模块，如多种信号测量、幅值定义、标定曲线制作、混频等，从而摆脱了对国外同类软件的依赖。试验和现场应用结果表明，该算法取得了很好的数据分析效果，达到了国外同类软件的水平，完全能满足核电站蒸汽发生器传热管役前与在役检查涡流数据分析的要求。

The analysis of the collected data in the eddy current inspection of the steam generator heat transfer tube is an essential part of ensuring the operation of steam generator under safe working conditions. This necessarily needs to be done through related software. However, the work of nuclear power in China still relies mainly on foreign related data analysis software to complete. In order to reverse this situation, this paper tries to investigate the related algorithms and techniques of eddy current data analysis and to implement a steam generator heat transfer tube eddy current inspection data analysis software. The software system solves the basic function modules needed in the eddy current inspection of the heat transfer tube of the steam generator of the nuclear power plant, such as multiple signal measurement, amplitude definition, calibration curve production, mixing frequency, etc., thus freeing the company from dependence on similar foreign software. The experimental and field application shows that the algorithm achieves good effect of data analysis and reaches the level of similar foreign software, which can fully meet the requirements of the SG heat transfer tube pre-service and in-service inspection for eddy current data analysis.
