Optimization method for visualization of electric power communication network

Abstract

The invention discloses an electric power communication network visualization optimization method, which comprises the following steps: (1) initial network layout: calculating all node coordinates ata rear end by using a force steering layout algorithm, and carrying out persistent storage on the node coordinates; and (2) network dynamic layout: calculating initial coordinates according to the connection relationship with the existing nodes for the newly added nodes, and adjusting the layout of the local network; and (3) network hierarchical visualization: carrying out visualization on the local part of the large-scale network, and carrying out incremental loading and pre-caching on the nodes and the relationship. According to the method, the problems of complex operation and unreasonablelayout in manual layout of a large network, unfixed node positions in automatic layout, too low rendering speed in a visualization process and the like are solved. On the premise of accurate and complete expression of a network topology structure, uniform layout, stable structure and smooth rendering of the network are ensured, and the operability and availability of the visual network are improved to a certain extent.

Description

【Technical field】 [0001] The invention relates to the technical field of power communication software development, in particular to an optimization method for power communication network visualization. 【Background technique】 [0002] The topology of the power communication network is becoming more and more complex, and the number and types of network element objects to be managed are increasing day by day. Multiple sets of professionals are often required to manage various types of network elements separately. The network visualization system can assist users to quickly understand the network structure and dig deeper into the network. The hidden value inside the data. Among them, the node-link diagram is the most general and reliable form to express the structure of the electric power communication network, but with the increase of the number of network element objects, the data scale gradually expands, and the node-link diagram is prone to the situation that nodes and links...

Among them, the force-directed layout algorithm is the most common, but the force-directed layout needs to be iterated continuously, and the time complexity is very high. When there are too many network nodes, the number of iterations required will increase, and the required layout time will also increase.

The initial coordinates of all nodes in the force-directed layout algorithm are randomly generated, which may cause changes in the network layout obtained by calling the layout algorithm multiple times, which is not conducive to users' grasp of the network structure

When the front-end is visualized, the GC overhead may be too large due to the large amount of data occupying the memory, and there may also be problems such as unsmooth animation, drawing canvas freezes, and page freezes.
