Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a satellite low-frequency cable design system, a design software framework and a design method. Background technique [0002] With the rapid development of electronic science and technology, more and more electrical control systems have replaced the existing mechanical control systems to meet the needs of aerospace products for miniaturization, light weight, standardization, modularization, and integration. There are also increasingly stringent requirements. Cables are an indispensable part of modern electronic products. The wiring, layout, processing and electrical installation of cables are also one of the important links in the manufacturing process of aerospace products, and they are also one of the more arduous tasks. The rationality of the layout and The safety and reliability of installation directly affect product performance, R&D costs and design cycle. [0003] For...

AI Technical Summary

Problems solved by technology

[0006] For complex and miniaturized products, the internal structure is complex and compact, the wiring space is narrow and irregular, and the diversity of functions makes the wiring between various devices increasingly complex, and the stand-alone structure and electromagnetic environment also pose challenges to the wiring. More stringent requirements, relying mainly on manual operation experience, the layout path is difficult to obtain, and it is time-consuming and labor-intensive, resulting in low accuracy of the obtained result data

In order to obtain a better solution to ensure product quality, it is necessary to extend the manufacturing cycle of the product and increase the manufacturing cost

[0007] (3) Lack of an intuitive and effective specification and description of the cable layout scheme, it is difficult to make an overall plan for the cable layout

At present, many commercial software industries such as CATIA, Pro / E, etc. basically meet the requirements in terms of structural design, but in terms of cable design, the existing modules of Pro / E cannot meet the design requirements, so the cable design module of Pro / E For example, it can meet the design requirements when the number of cables is small (several to dozens of levels)

[0009] However, for the massive cables of hundreds / thousands of on-board products, there are problems such as low wiring design efficiency, cable models cannot be opened separately, cable design modifications, cable diagrams, and report inconveniences cannot be realized. The mechanism cannot adapt to the complex design requirements of spaceborne products, and the design process is very inhumane, and the workload has not been reduced. Direct wiring interference detection of cables cannot be performed. After the wiring is completed, the corresponding 3D process information cannot be output, which does not reflect Advantages of 3D Design
