Detailed Description
Example 1
As shown in fig. 1, this embodiment discloses a big data retrieval method based on association of a three-dimensional model and a document, which includes:
step 1, converting an original format three-dimensional model file into a neutral format three-dimensional model file, and generating an archiving information packet after the conversion is successful;
step 2, carrying out light weight treatment on the archived information package, converting the neutral format three-dimensional model file into a lightweight model file, generating a propagation information package of the lightweight model file after the conversion is successful, and distributing the propagation information package to users;
step 3, importing model attributes in the archive information package into a configuration management database for storage and management, and establishing a device information configuration relation;
step 4, initializing an index table, performing traversal search on the document in the document system, and respectively establishing the index table for metadata information and document content of the document based on the equipment configuration information;
and 5, the configuration management database receives an index instruction of the client, determines an associated file list according to the index instruction, sends a document calling request to a document management system, and provides document contents according to the authority.
In step 1, the function of the three-dimensional model file neutralization format conversion is to convert the three-dimensional model generated by the professional three-dimensional design software into a format, and convert the three-dimensional model into a specific three-dimensional model file, such as DGN format and DRV format of an interscan PDS, or RVM format of AVEVA PDMS, and convert the three-dimensional model file into a neutral industry standard format which can be opened by various three-dimensional software, such as STP file and FBX file; is the first step of realizing the three-dimensional model big data retrieval association.
As shown in fig. 2, the specific steps of converting the neutralization format of the three-dimensional model file are as follows:
s101, generating data for a three-dimensional model, wherein the data comprises a model and model attributes for data verification;
s102, performing file four-way detection (namely, authenticity, integrity, availability and security detection) and integrity verification, wherein the verification is successful to form a SIP (Source Information Package) data packet, and an error report is generated when the verification is failed;
s103, performing neutral format conversion on the SIP data packet, generating a AIP (Archiving Information Package) data packet after the conversion is successful, and generating an error report when the conversion is failed;
s104, archiving the generated AIP data packet to finish the model archiving work of the original format and the neutral format.
In step 2, in order to facilitate online browsing of the model, and separate from a specific three-dimensional application software to open the model, since the data size of the three-dimensional model is large, the model in a complex scene often contains hundreds of thousands of polygons, and online browsing using WEB can lead to problems of long opening time, slow browsing speed and the like, the complex three-dimensional model needs to be subjected to light-weight processing, and the precision and number of the polygons in the model are reduced, so that the quick opening and browsing are facilitated.
As shown in fig. 3, the specific steps of the light-weight processing of the complex three-dimensional model are as follows:
s201, receiving an AIP original format information packet, repeating the verification of information in the light weight process, and forming an AIP receiving packet;
s202, performing model lightweight conversion to form a DIP (Dissemination Information Package) information packet. The storage format adopted by the light weight is BSON format, and the graph in the original format is compressed, wherein the compression ratio is about 20% -30%. The model is subjected to light weight treatment, so that the original viewing precision is kept, and the rendering of the WEB terminal is facilitated;
s203, archiving the original model, the neutral format model and the lightweight model file is completed.
The facility objects of the three-dimensional model include building (construction) structures, systems, equipment, components, and the like. To facilitate management from different dimensions, the system can be decomposed in terms of system functionality and spatial location. In step 3, attribute information (Metadata), also called Metadata information, in the three-dimensional model records the specific role of a certain component in the model, such as the length of the pipeline, the temperature, the parameters of the liquid in the pipeline, or the name of the equipment, the specialty, the sub-systems to which the equipment belongs. This information is stored as core content of the three-dimensional model by means of a configuration management database (Configuration Management Database). The relationship of the device to the device, the relationship of the device to the structure and system, and the device bit number and other information of the device are recorded. The system can disassemble and strip attribute information in the three-dimensional model, import the attribute information into a configuration database and analyze the attribute information by the configuration database.
As shown in fig. 4, the mining and analysis module of the three-dimensional model data includes the steps of:
s301, after archiving is completed, analyzing the model file, and disassembling the model attribute;
s302, importing the equipment attribute parameter information into a configuration management database;
s303, carrying out data analysis and reconciliation, and carrying out association of equipment information with the factory object;
s304, establishing an association display relation and realizing foreground display.
In step 4, mass files existing in multiple systems are analyzed and processed using big data retrieval techniques. For example, according to the type of the file, such as the file belonging to engineering design-related, purchasing-related, construction-related, debugging-related or project-management-related; or indexing according to the file metadata or the device numbers acquired in the text.
As shown in fig. 5, the big data retrieval includes the steps of:
s401, receiving information of a device configuration information database;
s402, initializing an index table, and requesting file classification traversal;
s403, reading document metadata information, and establishing/updating a metadata index;
s404, performing full text OCR (optical character recognition) on document content, and establishing/updating a full text index;
s405, analyzing and processing mass files existing in a plurality of systems by utilizing a big data retrieval module to finish big data indexing.
The index table style is shown in Table 1:
TABLE 1
In step 5, the interaction between the configuration management database and the big data retrieval is configured, the configuration management database regularly performs cross comparison and analysis on the configuration information and the index information in the big data retrieval module, for example, the associated equipment bit number in a certain three-dimensional model is indexed, and the information such as the corresponding two-dimensional document, drawing, report, record and the like in the file system is found by searching the document content and the file metadata attribute through the whole text.
As shown in fig. 6, the interaction of the configuration management database and the big data retrieval module includes the steps of:
s501, the device information configuration database periodically performs cross comparison and analysis on the configuration information and index information in the big data retrieval module
S502, a user browses specific three-dimensional models or P & ID information, and a device information configuration database inquires device position number information;
s503, retrieving file content and metadata by big data;
s504, returning to a user associated file list;
s505, the user clicks a specific file to be checked, and the document management system provides file contents according to the authority.
