Embodiment Construction

[0014] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0015] see figure 2 , 3 , the present invention provides a method for real-time drawing of power WebGIS vectors based on GPU, which is a method for realizing large-scale power data drawing in combination with GPU hardware acceleration through mainstream client technology on the Internet network. The method is roughly as follows: The size of the window is calculated to calculate the current vector object to be presented, and if the vector object is a line or a plane, it will be cut appropriately. Dynamically create textures based on vector object information, use Stage3D technology, call OpenGL / ES2 or DirectX, and finally render and present through GPU. It specifically includes steps:

Abstract

The invention provides GPU-based (graphics processing unit-based) real-time drawing method and device for power WebGIS (web geographic information system) vector. Through power line data acquisition, window clipping, texture creating and GPU drawing and rendering, GPU hardware acceleration technology and power WebGIS vector real-time drawing are combined effectively. By an efficient graphic rendering function of the GPU hardware acceleration technology and the function of batch data vector drawing, efficiency and timeliness of clients are greatly enhanced. In addition, the asynchronous response capacity of the GPU allows the system to be fast in interface response, so that user experience is improved and an efficient and visual solution is provided for vector drawing of power grid batch data.

Description

technical field [0001] The invention relates to a power system data drawing method, in particular to a GPU-based power WebGIS vector real-time drawing method and device. Background technique [0002] With the development of power grid construction and renovation projects across the country, in order to meet the requirements of "safety, reliability, high quality and high efficiency" of the power grid, it is necessary to use information technology for planning and design, strengthen the management and monitoring of power grid equipment, improve the reliability of power supply, and realize Digitalization and informatization of the power grid to provide users with efficient, high-quality, and safe services. [0003] Power WebGIS (GIS: Geographic Information System, is a network geographic information system based on B / S architecture and applied to the power system. It can realize the centralized sharing of various data of the power grid, integrate various applications of the pow...
