AI Technical Summary

Technical Problem

In the current process of asphalt mixture paving, temperature monitoring relies on manual methods, which makes it difficult to achieve full-section, continuous and high-precision temperature field management. This leads to quality problems such as uneven temperature causing differences in compaction, segregation and reduced smoothness. Moreover, the control methods are lagging and crude, making it difficult to cope with complex construction environments.

Method used

By combining infrared temperature matrix with millimeter-wave radar, multi-source data of the paving area is collected in real time. Through physical heat transfer equations and artificial intelligence prediction models, a three-dimensional temperature field tensor is generated, and hierarchical control commands are output to achieve precise control of the paver and material transport vehicle, and the model parameters are dynamically updated to adapt to complex environments.

Benefits of technology

It achieves high-precision prediction and active control of the temperature field, eliminates temperature differences, improves paving quality, reduces energy consumption, and ensures the consistency and stability of construction quality.

Abstract

The invention relates to an intelligent regulation and control method and system for a pavement asphalt mixture paving temperature field, computer equipment and a computer readable storage medium. The method comprises the steps that an infrared temperature matrix, internal temperature gradient data and environment and equipment operation parameters of a paving area are collected; and based on the temperature gradient data, carrying out compensation correction on the shielding area in the infrared temperature matrix. And fusing the corrected surface temperature matrix with the internal temperature gradient data to form a three-dimensional temperature field tensor. And inputting the tensor into the prediction model, and outputting future temperature field prediction data in combination with environment and equipment parameters. And generating a hierarchical control instruction set according to the local temperature difference, the temperature change slope and the lowest temperature threshold in the prediction data, and distributing the hierarchical control instruction set to a corresponding execution system. And acquiring actual temperature data after instruction execution, calculating errors and dynamically updating prediction model parameters. The paving uniformity, compactness and long-term durability of the asphalt pavement are improved.
