Stepless zooming display method and system for spacecraft hierarchical power supply and distribution big picture

Abstract

The invention provides a stepless zooming display method and system for a spacecraft hierarchical power supply and distribution big picture. The method comprises steps of establishing a three-dimensional coordinate system; obtaining different layers of the spacecraft hierarchical power supply and distribution big picture, and according to a layer display sequence, sequentially placing each display layer in the three-dimensional coordinate system in a way of paralleling to a plane of any two coordinate axes at intervals; according to the coordinate of each layer in the third axis direction in the three-dimensional coordinate system and the size relation between the top layer and the bottom layer, obtaining an activation threshold and the zooming scale corresponding to each layer; and according to a present browse zooming factor, comparing the activation threshold corresponding to each layer, and obtaining a corresponding zooming scale to automatically zoom each layer. The invention can achieve zoom-in and zoom-out of each layer and smooth switching among all layers without requiring manual debugging, so that the drawing efficiency and quality of the spacecraft hierarchical power supply and distribution big picture is greatly improved.

Description

technical field [0001] The invention belongs to the design field of power supply and distribution systems of spacecraft, and mainly relates to a method and system for steplessly zooming and displaying a large hierarchical power supply and distribution map of spacecraft. Background technique [0002] The power supply and distribution map is an important carrier that reflects the spacecraft power supply, power distribution, electrical signal transmission, and equipment power supply interface, and is an important content of the overall design of electrical components in the spacecraft. [0003] With the increasing number of electrical components in the spacecraft, the power supply distribution becomes more and more complex. In order to express the power supply and distribution information of the spacecraft more clearly, the current power supply and distribution diagram is usually designed according to the hierarchical thinking; usually, the The spacecraft power supply and distr...

AI Technical Summary

Problems solved by technology

[0005] The design process of this kind of hierarchical power supply and distribution diagram needs to draw multiple drawings with different granularities, which requires a lot of repetitive work. However, during the display browsing process, when switching between different levels, there are too many interface interactions, which makes the user in the establishment. Obstacles arise when there are associations between different levels, resulting in low efficiency in browsing and locating information
