AI Technical Summary

Technical Problem

Existing HPLC route optimization methods struggle to distinguish between high-quality paths affected by transient interference and low-quality paths that deteriorate over time when faced with transient interference in power line channels and changes in node resource occupancy. This leads to frequent route switching and unstable data transmission.

Method used

By collecting and filtering communication success rate and relay load rate, fluctuation mode characteristic indicators and link instability are calculated. Combined with node resource reserves, the routing path is dynamically adjusted to avoid frequent switching and prioritize the maintenance of stable and resource-rich paths.

Benefits of technology

This effectively avoids frequent path switching caused by momentary interference, ensuring the stability of the HPLC network and the reliability of data transmission, and reducing data transmission failure time.

Abstract

This application relates to the field of digital information transmission technology, specifically to a dynamic optimization method and system for HPLC routing based on link quality. The method includes: collecting the original communication success rate and original relay load rate of the end meter and its adjacent nodes according to a preset sampling period, and preprocessing them respectively; identifying asymmetric pattern characteristics of link fluctuations by calculating the weighted ratio of the cumulative increase and decrease of the original communication success rate; quantifying the link instability index by combining the path foundation weakness and fluctuation penalty factor; calculating a stability-enhanced routing score based on filtered communication success rate, node resource margin, and link instability; and finally selecting the optimal proxy node to complete the route update based on the score. This application achieves adaptive protection of high-quality paths, effectively suppressing routing oscillations caused by transient interference, and improving the stability and data transmission reliability of the HPLC network in complex environments.
