Tunneling roadway space topology network model updating method and device

Abstract

The invention provides a tunneling roadway space topology network model updating method and device. The method comprises the following steps: acquiring an original roadway spatial topology network model, newly added roadway data and a roadway data table, and assigning values to a roadway center line and a traverse point in the newly added roadway data according to the roadway data table to determine an attribute value of the roadway center line and an attribute value of the traverse point; when detecting that the traverse point is not matched with the correct roadway center line to which the traverse point belongs, correcting the traverse point to the correct roadway center line; when it is detected that there is no traverse point at the roadway turning position or the roadway intersection, supplementing virtual traverse points, and determining the coordinates z of the virtual traverse points based on a search algorithm according to linear interpolation; detecting a newly-added roadway, determining a connection mode of the original roadway and the newly-added roadway, and combining and connecting the new roadway to the original roadway space topology network model by adopting a corresponding combination processing mode; forming a new roadway section according to the corrected traverse points and the virtual traverse points, and establishing a newly added encrypted section topology to update a roadway space topology network model.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a method and device for updating a roadway space topology network model. Background technique [0002] The accuracy of the topological connection relationship of the mine roadway space topological network model depends largely on how to analyze and process the error data. In related technologies, the roadway space topology network model is often established by extracting information from the excavation engineering plan, but this method is not applicable to all roadway types. And in the current research on the automatic correction of traverse points, solving the z coordinates of virtual traverse points at roadway turning points and intersections, and the continuous updating of the roadway spatial topology network model with the increase of mining depth, there is a problem that the spatial traverse point is not on the roadway centerline Above all, there is a lack of gui...
