Real-time slicing method for vector graphic data of power grid equipment and storage medium

Abstract

The invention discloses a real-time slicing method for vector graphic data of power grid equipment and a storage medium. The method comprises the steps that a server obtains drawing data and a graphicrendering configuration table of the power grid equipment, and loads the drawing data and the graphic rendering configuration table to a memory; receiving a data query request sent by the front end,wherein the data query request comprises a coordinate range, an equipment type and a custom condition; querying drawing data of the corresponding power grid equipment according to the data query request; calculating a scale according to the coordinate range and the size of a drawing interface at the front end; obtaining a configuration scheme of the corresponding power grid equipment from the graphic rendering configuration table according to the scale and the equipment type; returning the drawing data and the configuration scheme of the corresponding power grid equipment to the front end; andthe front end draws the power grid equipment on the drawing interface according to the returned drawing data and configuration scheme of the power grid equipment. According to the invention, the system performance of graphic query and rendering can be improved.

Description

technical field [0001] The invention relates to the technical field of graphic data processing, in particular to a real-time slicing method and storage medium for vector graphic data of power grid equipment. Background technique [0002] At present, the access and rendering of graphic data are mainly divided into two modes, one is to tile the data in advance, process it into a file format, and directly obtain the file when accessing; the other is to directly access structured data by the front end, Data is processed and rendered on the front end. The first mode is usually used for applications that do not require frequent updates, such as electronic maps, and has the disadvantage of requiring a large amount of pre-tile processing work; the second mode is usually used for applications that require frequent data updates, such as industry graphic display, and has performance Lower cons. [0003] The display of power grid equipment graphics usually adopts the second mode menti...

Problems solved by technology

The first mode is usually used for applications that do not require frequent updates, such as electronic maps, and has the disadvantage of requiring a large amount of pre-tile processing work; the second mode is usually used for applications that require frequent data updates, such as industry graphic display, and has performance lower disadvantages

[0003] The display of grid equipment graphics usually adopts the second mode mentioned above. Although it can be optimized at the application level, it is still limited by the architecture and cannot meet the requirements of high performance and real-time update.
