AI Technical Summary

Technical Problem

In existing asphalt pavement maintenance technology, the maintenance window is fixed, and it is impossible to dynamically adjust the operation sequence of each process according to real-time weather changes. This results in a process being forced to be interrupted due to unsuitable weather, while the overall maintenance operation is forced to stop when other processes can still be carried out, causing idle labor and waste of resources.

Method used

By collecting local meteorological parameters and forecast data in real time through edge computing nodes, the meteorological suitability conditions of each maintenance process can be configured independently, the operation sequence of the process can be dynamically adjusted, the meteorological suitability at the process level can be refined, and the unfinished parts can be automatically drifted to the next workable window under meteorological disturbances, while the subsequent suitable processes can be inserted forward to ensure the continuity and economy of maintenance operations.

Benefits of technology

It enables differentiated weather suitability determination for each maintenance process, avoiding idle labor and resources, ensuring the continuity and economy of maintenance operations under weather disturbances, reducing material waste and rework, and improving the autonomous continuity and robustness of maintenance operations.

Abstract

This invention discloses a method for periodic maintenance of low-carbon asphalt roads based on edge computing. This invention relates to the field of road maintenance technology and solves the problems of fixed maintenance windows, inability to dynamically adjust the operation sequence of each process according to real-time weather changes and forecasts, and the inability to reflect the differentiated weather requirements between processes due to all processes sharing the same weather window. This invention independently configures differentiated weather suitability thresholds for each maintenance process type, such as milling, paving, compaction, sealing, in-situ thermal recycling, and crack repair. These thresholds include lower temperature limit, lower pavement temperature limit, upper humidity limit, upper wind speed limit, and upper rainfall intensity limit. This achieves refined weather suitability determination at the process level, overcoming the shortcomings of processes being tied to the same weather window for decision-making. When a process is forced to be interrupted due to unsuitable weather, other unaffected processes can be adjusted to execute within the current window through a forward insertion mechanism, avoiding idle work and resource downtime.
