Cable network branch diagram manufacturing method based on topological graph automatic layout

Abstract

The invention provides a cable network branch diagram manufacturing method based on topological graph automatic layout. The method includes the following steps of browsing a cable network model structural tree and reading three-dimensional cable network model information to obtain all cable wire harness information (2) of a cable network model, and browsing all branches for a certain cable to obtain information of two ports of the cable and the length information; thirdly, browsing a connecting relation list, and establishing an adjacency list; fourthly, arranging all vortexes on grid points through the combination of tree-shaped layered layout and mesh layout, and calculating the actual positions of the nodes in the page according to the grid positions of nodes and the size of the page; fifthly, folding up branch diagrams; sixthly, browsing all the nodes on a trunk, doing different movements according to the types of the nodes so that no crossing or overlapping happens to drawing of the branch diagrams; seventhly, marking the length of connecting cords of the branch diagrams; eighthly, sequentially drawing other cable branch diagrams, and outputting the branch diagrams drawn in batches into a file for guiding production.

Description

technical field [0001] The invention relates to a method for making a branch diagram of a cable network based on the automatic layout of a topological diagram. By reading three-dimensional cable model information, establishing a connection relationship table, establishing an adjacency table, creating a tree-shaped grid layout topology diagram, and adjusting the tree-shaped grid layout The topology diagram is gathered and the nodes are moved to avoid obstacles, so as to finally make the wiring harness branch diagram. Background technique [0002] The branch diagram of the cable network is used to guide the cable network production unit to produce the cable network, and it is generated according to the bundle. The traditional method is to flatten the 3D trend model in the 3D environment through the software flattening module after the 3D trend model of the cable network is established. to the two-dimensional plane, and then manually adjust the position of the branches and conn...

Problems solved by technology

[0003] The number of communication satellite cable bundles is relatively large, reaching the order of hundreds of bundles. Manually making a bundle of cable branch diagrams requires steps such as flattening, projection, and labeling. The workload is heavy, the process is cumbersome, and the operation of the design software is complicated.

Moreover, the production of cable network branch diagrams is not a part of design, and the work does not generate added value. It is only a consumable work done for the convenience of the production unit for drawing production. After the 3D trend model of the cable network is changed, it is necessary to artificially make the branch diagrams. Go through the process again. In the traditional mode, this link consumes a lot of energy for the designer

In terms of quality, under the manual operation mode, low-level quality problems such as missing labeling of connectors and missing labeling of branch diagram lengths are prone to occur.
