System software (function description and interface display)
It adopts gantry type and matches the ground track. The probe holder can move freely left and right to adapt to rims with different gauges.
The flaw detector is digitalized, modularized, with strong interchangeability and scalability, which is convenient for maintenance;
—The flaw detector has high technical indicators and meets national and European standards;
—The components of the system are of military grade, with high stability, anti-interference and reliability, excellent signal-to-noise ratio, and strong ability to find defects;
—All data of the system can be saved, recalled, and output, which is convenient for later traceability;
—The system contains a flaw detection expert system, which can calibrate the equipment on schedule, and then enter the normal working mode after calibration;
—The system is fully automated, without manual intervention.
