A cable pipe gallery path planning method and system

Abstract

This invention provides a method and system for cable tunnel route planning. The method includes: acquiring and integrating geological survey data, existing pipeline network data, structured specifications, and unstructured documents of the planning area; parsing the unstructured documents using a visual language model to extract textual semantic constraints and associate them with spatial entities to generate a semantic constraint layer; integrating the semantic constraint layer, geological data, and pipeline data to construct a unified three-dimensional mesh constraint field through quantitative encoding; based on this constraint field, employing a hierarchical decision-making strategy, first performing a global path search that integrates multi-dimensional states, and then using a local optimization algorithm based on physical motion constraints to smooth and verify the feasibility of the path, generating a continuous and constructable three-dimensional path; finally, outputting an interpretable report of the path and all associated constraints. This invention realizes automated and intelligent planning of cable tunnel routes, moving from reliance on manual experience to data and model-driven approaches.
