Abstract

The invention discloses a method for extracting an indoor branch link topological relation based on CAD drawing data. The method comprises the following steps: S1, collecting data; s2, uploading drawings: uploading indoor coverage design drawings through an intelligent indoor distribution monitoring system; s3, drawing information extraction: enabling the intelligent indoor distribution monitoringsystem to generate a handshake file, analyze and monitor the handshake file, read an indoor coverage design drawing and perform drawing information extraction work; s4, analyzing the drawing information, and carrying out drawing frame data matching and data type conversion; s5, performing classifying according to the legend information in each picture frame, extracting the legend information, andoutputting a json format text to a specified directory in combination with indoor distribution equipment information; extracting an indoor distribution coverage floor system diagram equipment association relationship, outputting an indoor distribution equipment association relationship text of each floor to a specified directory, and generating an associated handshake file; s6, generating a planar graph and point location information; and S7, carrying out hierarchical presentation: enabling the front-end page to acquire the indoor distribution topological data from the background to perform hierarchical presentation.

Description

technical field [0001] The invention relates to the technical field of the combination of computer technology and graphics, in particular to a method for extracting the topological relationship of room division links based on CAD drawing data. Background technique [0002] With the acceleration of operators' 5G network construction, the continuous expansion of network scale, and the continuous improvement of service requirements, operators pay more attention to the user's indoor perception. However, the basic maintenance work is under enormous pressure. The traditional passive indoor distribution system (DAS) has become a pain point in network quality due to the large number of passive nodes, complex distribution structure, poor alarm capability, and weak management and maintenance capabilities. Traditional room dividers use a large number of passive components, and the quality of components and construction is difficult to guarantee. And with the years of disrepair, proble...
