The invention discloses a SQUID-based wing detection system and a detection method thereof. The SQUID-based wing detection system comprises a data acquisition module provided with a SQUID, a non-magnetic dewar container, an upper computer and a system bracket, wherein the upper computer is electrically connected with the data acquisition module; the data acquisition module is placed in the non-magnetic dewar container capable of keeping the SQUID in a superconducting state; the non-magnetic dewar container is fixedly arranged on the system bracket; and during detection of a wing, the data acquisition module acquires the change of a magnetic signal of the wing which moves freely on the system bracket through the SQUID, transforms the magnetic signal into an electric signal, and transmits the electric signal to the upper computer for computing and processing. Through adoption of the SQUID-based wing detection system, damage of the wing caused by pits generated by collision can be scannedfully, and parameters such as positions, depths and diameters of the pits are displayed on a display instrument in real time. The wing detection system and the detection method thereof have the characteristics of simple process, rapidness, high efficiency and high detection accuracy.
Description
technical field [0001] The invention relates to the technical field of magnetic resonance exploration instruments, in particular to a SQUID-based wing detection system and a detection method thereof. Background technique [0002] At present, in the domestic aircraft maintenance work, when the wings are subjected to external forces such as hail and cause pits, when performing maintenance, the maintenance engineer usually checks visually, and then marks, measures and records by hand , and judge whether the pit needs to be repaired. Such a work process not only requires more manpower, but also the measurement accuracy is greatly affected by human factors. [0003] Chinese patent CN201510756405.2 discloses a system for automatic detection and marking of wing pits in aircraft maintenance, including at least one scanner, walking frame driving device, scanner walking frame, working platform support, control panel, console , a control device, a plurality of working platform moving...
