Problems solved by technology

Both of these two solutions increase the workload and difficulty of work, which is not conducive to rapid page release. The existing data update solutions generally use the front-end page to request refresh at regular intervals, which cannot take into account the real-time and reliability requirements of power system data.

Abstract

The invention discloses a configuration graph web publishing method based on canvas. The configuration graph web publishing method comprises the following steps: exporting a template xml file and a picture xml file respectively by using a configuration tool; analyzing the template xml file and the picture xml file through front-end js, performing drawing based on canvas, generating a page primitive object and caching the page primitive object to an object list; establishing a websocket connection between the front end and the server side; and controlling a data updating module of the server topush change data to the front-end page when data change is detected, and controlling the front-end page to redraw the corresponding page primitives. By proposing a new general configuration publishing format, a data updating scheme is improved, and the requirements of a power system monitoring platform on the real-time performance and reliability of monitoring data are met by adopting a mode of combining regular refreshing and change pushing, taking change pushing as a main mode and taking regular updating as an auxiliary mode.

Description

technical field [0001] The invention relates to the technical field of power system monitoring, in particular to a canvas-based web publishing method for configuration graphics. Background technique [0002] In recent years, the power monitoring system tends to be more and more remote monitoring on the web side, which has the advantages of simple and beautiful screen, lightweight application (no need to install additional client software, only a browser is required). The configuration graphics web release can publish the monitoring screen to the web system, making the real-time screen monitoring of the substation more convenient and faster. Currently, two schemes are widely used for web publishing of configuration graphics: one is to redraw the configuration graphics of the web version with reference to the monitoring screen; the other is to analyze and draw based on the existing configuration files. These two solutions increase the workload and difficulty of work, which is...
