Abstract

The invention relates to an urban core area underground pipe network virtual collision detection and positioning integrated method and device. The method comprises the following steps of obtaining standardized underground pipe network data; according to the attribute characteristics of the underground pipe network, carrying out linear search along the pipelines based on the standardized underground pipe network data by a fast focusing algorithm, and acquiring potential intersecting pipelines; calculating a linear vector product of the pipeline for each potential intersecting pipeline, and obtaining an intersection point of the pipeline on a two-dimensional geometric plane; based on the standardized underground pipe network data, performing three-dimensional analysis on pipelines with intersections, judging whether the pipelines have virtual collision in a three-dimensional space or not, and if so, calculating to obtain plane positions and depths of the intersections of the pipelines; and based on the plane position and depth of the intersection point of the pipelines with virtual collision, repositioning the collided pipelines according to a pipeline arrangement principle. Compared with the prior art, the invention has the advantages of high detection precision and efficiency, automatic repositioning and the like.

Description

technical field [0001] The invention relates to the technical field of underground pipe network layout, in particular to an integrated method and equipment for virtual collision detection and positioning of underground pipe networks in urban core areas. Background technique [0002] The underground pipeline network in the urban core area is a huge and complex system, with a wide variety of pipelines intertwined vertically and horizontally. In the process of pipeline detection, the detection signal will be affected by factors such as adjacent and superimposed pipelines and the surrounding environment. The pipeline detection data will inevitably produce plane position and buried depth errors, resulting in conflicting or overlapping positions between pipelines, that is, virtual collisions. It cannot objectively and truly reflect the spatial distribution of underground pipelines, and brings great construction difficulties to pipeline design, layout, relocation, etc., and cannot ...

AI Technical Summary

Problems solved by technology

There are also technicians who determine the intersection point of the underground pipeline on the two-dimensional plane through two steps of fast focusing and accurate intersection, and then combine the buried depth and diameter of the pipeline to judge whether virtual collision detection occurs, which improves the virtual collision detection to a certain extent. Efficiency, but for pipelines that collide, technicians still need to manually adjust according to various factors such as pipeline size, material, use, trend, etc., which is highly professional, heavy workload, low relocation efficiency, and time-consuming.
