Abstract

The invention discloses a power grid GIS data storage method based on version control. The method comprises the following steps: 1, dividing power grid data into power grid network frame layer data and power grid operation data, analyzing the space, attributes, time and behavior characteristics of the data, and building a database table for storing the information; 2, setting correction state time, and establishing a ground state snapshot; 3, storing the ground state snapshot into a database; establishing a ground state index table, a historical ground state table and a current state table; 4,performing version iteration on the ground state snapshot; periodically updating the correction state of the ground state according to the set correction state event; and step 5, querying and browsing the power grid data at any moment through different ground state time. According to the method, the problems of concurrence and combination in the data version updating process can be effectively solved, the consistency and integrity of data are ensured, and the management level of historical data is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power GIS mass data storage and query, and in particular relates to a version control-based power grid GIS data storage method. Background technique [0002] With the increasing scale of the power grid, the development and change of the power grid is accelerating. How to accurately and intuitively display the development and changes of the power grid scale and wiring, and predict the law of future power grid planning and construction. The traditional GIS system can only reflect the state of the power grid in the recent period, and lacks effective support in terms of historical information tracing and future power grid development prediction. [0003] Temporal GIS uses the direct relationship between the power grid model and the time model, and integrates temporal semantic SQL technology to realize fast query and browsing of historical data, allowing the GIS system to enter the "four-dimensional" ...
