The invention relates to the technical field of PCIe (Peripheral Component Interconnect Express), in particular to a PCIe dynamic degradation type link resetting method and system. Comprising the following steps: S1, continuously reading the LTSSM state of a PCIe link, recording the duration of an abnormal state, and when the duration exceeds a preset threshold value, judging that timeout abnormity exists; s2, after the abnormal early warning is received, a dynamic degradation reset instruction for the NVMe controller is initiated; s3, the state machine control unit takes over the reset link initialization process and follows the physical layer priority gt; the link layer is preferentially gt; a priority strategy is simplified by a transaction layer, and a centralized resource guide link rapidly completes training and enters an L0 state. Compared with the prior art, the method has strict protocol compliance, the reset efficiency is improved, and the overall stability and performance of the system are optimized.

This invention discloses a method for cleaning the edge baffle of a continuous hot-dip galvanizing visible air knife, characterized by the following steps: S1, offline mode: during production preparation, after the air knife is connected to the gas pipeline and electrical connector, the edge baffle of the air knife is in an offline position for action testing; S2, online mode: after the production line starts and the strip steel runs, once the air knife is in normal operation, the edge baffle of the air knife begins to move from the offline position to the online position; S3, edge baffle cleaning mode; S4, air knife lip cleaning mode. This invention also discloses a device for cleaning the edge baffle of a continuous hot-dip galvanizing visible air knife, comprising: an edge baffle bracket, installed on the top of the edge baffle of the air knife; two sets of camera monitoring components, respectively installed on both sides of the front end of the edge baffle bracket, for monitoring the two sides of the edge baffle of the air knife; and two sets of scraper drive components, respectively installed on both sides of the rear end of the edge baffle bracket.

The invention relates to the technical field of battery sealing nail welding, and provides a battery sealing nail welding defect repairing method. The repairing method comprises the following steps: acquiring an aluminum wafer of which the diameter is greater than that of a liquid injection hole of the battery top cover; removing the sealing nail at the liquid injection hole of the top cover of the battery; cleaning a liquid injection hole area; carrying out penetration type stitch welding by taking the wafer as an upper layer and the battery top cover as a lower layer to form a welding seam for melting the wafer and the battery top cover into a whole; and treating the welding seam and the wafer, enabling the outer surface of the wafer to be flush with the outer surface of the battery top cover, and enabling the liquid injection hole area not to be visually recognized. According to the repairing method, the aluminum wafer and the battery top cover are subjected to penetration stitch welding, and the welding seam and the surface of the wafer are treated, so that the welding defect of the sealing nail is repaired, the situation that the battery is degraded and scrapped due to poor welding or appearance defect of the sealing nail is avoided, and the quality requirement of the battery is met.

This invention discloses an identity authentication method integrating quantum-resistant signatures and the X.509 format, relating to the field of data security technology. The method includes: S1, CA generates and publishes globally public parameters; S2, EE1 and EE2 obtain Cert1 and Cert2; S3, EE1 and EE2 perform bidirectional authentication and session key negotiation, and communicate using the session key; constructing a quantum-resistant digital identity certificate to ensure the long-term security and traceability of registration information; during the registration phase, the SLH-DSA algorithm is used to sign the user-submitted registration information to ensure the long-term validity and strong anchoring of the identity certificate, while the ML-DSA algorithm is reused to sign the registration information for rapid verification scenarios; during the authentication interaction phase, the ML-KEM quantum-resistant algorithm is used to implement a dual-path quantum-resistant DKE key exchange protocol to generate a session key, and the ML-DSA algorithm, with higher signature and verification performance, is used to digitally sign and verify the authentication message, achieving identity confirmation and communication integrity protection for both parties, and improving the performance of establishing a secure session link.
