Large image cache method based on power grid topological analysis, and display method and system thereof

Abstract

The invention relates to a large image cache method based on power grid topological analysis, and a display method and a display system thereof. The large image cache method comprises the step of computing cache weights of each node, and caching the nodes with the cache weights more than a set threshold, wherein computation of the cache weights specifically comprises the sub-step of comprehensively considering influence, vulnerability and topological structure characteristics of the nodes, and overlapping to form the final cache weights, wherein the influence is measured by tight centrality orbetweenness centrality of the node, the vulnerability is measured by an element online rate, and the topological structure characteristics correct the cache weight of the node according to the position of the node in a topological structure. Compared with the prior art, the method provided by the invention caches the nodes with better user preference according to priorities, and thus next front-end loading efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of system front-end browsing, in particular to the visual display of massive front-end data, and in particular to a large image caching method, display method and system based on grid topology analysis. Background technique [0002] The power grid system is a system with massive data and complex topology. In many power grid data analysis platforms, there is a need to visualize the power grid topology. However, the grid structure is complex and the amount of data is huge. Due to the limitation of network bandwidth and front-end loading and rendering performance, it is often inefficient to display such massive data and large images. [0003] There are many types of existing front-end caching technologies, such as browser caching, CND caching and other technologies, but most caching technologies are not targeted. When faced with the display of massive data and large images with complex topologies, the efficien...
