Abstract

The present invention provides a branch cable automatic layout method and device, which are used to solve the problem that the existing branch cable layout technology does not consider the optimization of branch points, which makes it difficult to obtain the optimal layout and the layout efficiency is low. The layout method of the present invention includes: according to the product CAD model and the wiring table, obtaining the position information of the branch cable connector terminal in the solution space; according to the position information of the branch cable connector terminal and the first preset algorithm, determining the position information of the branch cable connector terminal The position information of the branch point of the branch cable in the solution space; according to the position information of the branch cable plug terminal, the position information of the branch point and the second preset algorithm, generate obstacles covering the solution space A surface cable layout path diagram; according to the cable layout path diagram, a cable model is obtained and output as a layout design result. The invention not only satisfies the constraint of laying the cable against the wall, but also greatly improves the efficiency and success rate of the algorithm compared with the efficiency of the existing algorithm.

Description

Technical field [0001] The present invention relates to the technical field of branch cable layout design, in particular to a branch cable automatic layout method and device. Background technique [0002] Cable layout design is one of the important links in the R&D process of electromechanical products. Its work mainly involves the determination of the length and direction of the cable in the equipment, as well as the specific location of related trunking and clamps. With the development of mechanical and electrical products in the direction of complexity and precision, the work of cable layout design has become more and more arduous. The emergence and development of CAD technology has effectively improved the efficiency and quality of cable layout design. At present, computer-aided cable layout design mainly includes two methods: man-machine interactive layout design and automatic layout design. The automatic layout design technology has higher wiring efficiency due to the use o...
