Automatic Generation Method of Visual Network Diagram Based on GIS Technology

为了解决由于数据量大、繁杂而造成的测量点详细信息和点与点之间逻辑关系单一的问题,提出基于GIS技术的可视化计量网图自动生成方法。分析电网的拓扑结构,总结出生成可视化计量网图所需的计量拓扑数据组织,并引入GIS技术,将地形学高程分层映射至零平面内,将等值点内插在三角形网边缘上,追踪相邻等值点,获得点与点之间的逻辑关系,拟合出等值曲线,获得可视化计量网图的等高线,完成计量网络图的自动生成。实例测试结果表明,所提方法能够生成较为全面清晰地可视化计量网图,为相关人员管理电力数据提供便利。

In order to solve the problem of single measurement point detail information and logical relationship between points due to large and complex data, an automatic generation method of visual measurement network map based on GIS technology is proposed. It analyzes the topology structure of the power grid, summarizes the measurement topology data organization required to generate the visual measurement network map, and introduces GIS technology to map the topographic elevation to the zero plane, interpolates the equivalent points on the edge of the triangular network, tracks the adjacent equivalent points, obtains the logical relationship between points, fits the equivalent curve, and obtains the contour of the visual measurement network map, completes the automatic generation of metering network diagram. The example test results show that the proposed method can generate a more comprehensive and clear visual metering network diagram, which provides convenience for relevant personnel to manage power data.
