AI Technical Summary
Existing methods for monitoring the dynamic sealing performance of photovoltaic connectors are difficult to align data on the same time axis. They are affected by mechanical transmission dead zones and environmental thermodynamic factors, making it impossible to accurately assess sealing performance. Furthermore, they cannot identify the unidirectional torsion state of polymer seals, leading to inaccurate positioning of sealing failures.
By synchronously mapping the timestamps of multi-channel signals, the phase time difference between sensors is eliminated, the sealing cross-sectional area is located using the step physical abrupt change point, and the interference is eliminated by combining the calculation of environmental thermodynamic parameters, the deformation of the sealing component is quantified, the electromechanical delay is eliminated, and the sealing failure is accurately located.
It enables synchronous and accurate evaluation of the dynamic sealing performance of photovoltaic connectors, eliminates mechanical and environmental interference, accurately locates the sealing failure position, and improves the synchronization and accuracy of test data.
