Research on multi-source BIM data storage method based on smart grid equipment operation and maintenance stage

In view of the high dynamic characteristics of multi-source data in the operation, maintenance and repair stage of smart grid equipment, a multi-source building information modeling (BIM) data storage method for the operation, maintenance and repair stage of smart grid equipment is studied. The data interface adapter is used to connect the operation and maintenance related systems of the power system, collect the multi-source data of the operation and maintenance of power grid equipment, convert the collected data into multi-source BIM data using the data conversion engine, and transmit it to the MySQL database. The integrated operation, maintenance and repair multi-source data is retrieved from the MySQL database to build a multi-source BIM data model for power grid equipment. Use edge nodes to collect multi-source BIM data information, select compression sensing algorithm to reconstruct multi-source BIM data, form reconstructed data and sparse dictionary atoms and upload them to the cloud server, build a complete sparse dictionary, and realize multi-source BIM data storage. The simulation results show that the method can store multi-source BIM data for operation, maintenance and repair of smart grid equipment, the uploaded content is consistent with the read content, and the storage performance is superior.
