Description

A database device for IFC information model

technical field

The invention relates to a substation safety maintenance technology, in particular to a database device for an IFC information model.

Background technique

Since the concept of smart grid was introduced from abroad in the 1970s, a large number of digital substations using the IEC61850 standard system have been put into operation. The construction of domestic digital substations has been strongly supported and promoted by national policies and is developing in depth. At present, there are hundreds of digital substations that have been built and put into operation at home and abroad. The State Grid Corporation has approved dozens of the first and second batch of intelligent substation projects, and China Southern Power Grid has approved dozens of intelligent substations under construction. Despite this, the construction of intelligent substations still faces many problems: 1) Although the intelligent substations currently under construction or in operation all conform to the DL/T 860 standard, due to the different technical methods and intelligence levels used in various places, and The degree of intelligence between the completed stations and the stations under construction is also different, so the operation, maintenance and management methods of each station cannot be unified and standardized; 2) The monitoring systems of the equipment in the station are independent of each other, and the data cannot be directly converted, resulting in The difficulty of analyzing massive data is greatly increased; 3) The intelligent substation can only be designed once at the construction stage, and there is little room for improvement in the later period, and the expansion ability of the system is low.

However, due to the uniqueness of substations, which include electrical, HVAC, water supply and drainage, water fire protection, and civil engineering, a total of five professional contents, if the current database is used, it generally cannot be well adapted to the coordinated storage of various professional data. If the operation mode is not used, it will seriously affect the opening speed of the IFC information model.

Also includes:

Distributed database 1, connected with processing server 2, used to store IFC information model data by specialty;

The interaction component 3 is connected with the processing server 2 and is used to display the IFC information model. the

The data integration module is respectively connected with the data calling module and the display, and is used to integrate the IFC information model data of various professions, generate an IFC information model and send it to the display.

Based on the consideration of data stability and scalability, the choice of each sub-database uses the MySQL database. According to the formulation of IFC format, model conversion strategy and determination of monitoring data table structure, comprehensive consideration of factors such as data display, model display and data transmission and storage, the design of database is mainly divided into two categories: dynamic database and static database, and the data sources are respectively for real-time monitoring data and IFC models. The data conversion process and database architecture are shown in Figure 2.

It can be seen from the figure that each sub-database includes: original data layer, data conversion layer, data layer and database class, the database class includes static database and dynamic database, original Revit files in the original data layer and classifications in compliance with IFC4 Information and other management additional attribute information are converted into IFC4 files and FBX files in the data layer through the data conversion layer. The IFC4 file records the classification information, shape information and professional attribute information of each device, and the FBX file is used as a display The need for platform rendering and material paste stores additional material information and scene information; these information are stored in the database class as static information after the project is completed, although the management class attribute information will also be updated and changed, but because the change frequency is relatively Low and manually written, it can be classified as static database content.

At the same time, after the real-time monitoring information from the on-site status information collection equipment passes through the protocol conversion interface, it will be used as a dynamic database to maintain the same update rate as the frequency of the monitoring system, and it will be dynamically stored and automatically backed up.

The state information collection equipment collects the operation data of each equipment in the substation in real time.
