Abstract: It is a hotspot to employ multiple nondestructive testing methods for enhancing the probability of detection; meanwhile, there are increasing requirements for the rapidity, intelligence and integration in in-situ aviation NDT. A novel integrated ECNDT system was developed based on the universal model of eddy current testing system in principle and function. The system has modularized and reconfigurable system architectures and employs dual-bus structure: PCI and I2C. It contains not only functions of PECT, general ECT, MFECT, ACFM and AECT, but also integration of mutiple ECNDT methods because of modularized and reconfigurable system hardware and uniform data interface.
