[0043] The embodiments of the present invention provide a method, device, equipment and storage medium for storing three-dimensional building data.

[0044] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of a method for storing three-dimensional building data in an embodiment of the present invention includes:

[0046] 101. Obtain three-dimensional building data to be stored;

[0047] In this embodiment, the three-dimensional building data may be existing three-dimensional construction data such as STP, CGR, DWG, DGN, PLN, VWX, and RVT.

[0048] 102. Analyze and encapsulate the three-dimensional building data according to a preset analysis algorithm to obtain overall building data, building component data, and mapping relationship data of the three-dimensional building data, wherein the mapping relationship data includes: mapping relationship data between the building component data and the overall building data;

[0049] In this embodiment, the three-dimensional building data is analyzed, and then an overall identification is set for the three-dimensional building data to obtain the overall building data. The overall building data here includes both the entity data of the three-dimensional building data and the identification data. An identification symbol is assigned to the three-dimensional building data to confirm the uniqueness of the three-dimensional building data, and each building component such as door, window, floor and other component resources existing in the three-dimensional building data is assigned an identification symbol one by one, and the components in the three-dimensional building data are located by symbols, and then based on the association relationship between the components and the overall building data, the upper and lower relationships and spatial positions of the components in the overall building data are used as mapping relationship data.

[0050] Furthermore, the following steps may be performed at 102:

[0051] 1021. Setting identification for three-dimensional building data to generate overall building data;

[0052] 1022. Analyze the composition of the three-dimensional building data, set identifiers for components in the three-dimensional building data, and generate building component data;

[0053] 1023. Generate mapping relationship data based on the mapping relationship between the building component data and the building overall data.

[0054] In steps 1021-1023, the three-dimensional building data is identified as a whole, and then the three-dimensional building data is analyzed in turn, and each building component such as door, window, floor and other component resources are assigned identification symbols one by one to obtain building component data. Then, based on the association relationship between the component and the overall building data, the hierarchical relationship and spatial position of the component in the overall building data are used as mapping relationship data.

[0055] Furthermore, the following steps may be performed at 1022:

[0056] 10221. Traverse all the smallest unit files of 3D building data;

[0057] 10222. Set an identifier for each minimum unit file in turn, and encapsulate each minimum unit file into overall data to generate building component data.

[0058] In steps 10221-10222, the minimum metadata range of the 3D building data is analyzed to ensure that the result set of each piece of data can represent a sub-process of an inspection, and the combination of all the minimum metadata can trace back the complete inspection record of the drawing. Therefore, when defining metadata, it is necessary to record the mapping relationship between the building identification of the inspected drawing, the inspection rule identification and the data, so as to achieve data simplification on the basis of data integrity. The metadata result set generated during the inspection process is encapsulated into a data file and stored separately.

[0059] 103. Store the building component data in the mongoDB database, and store the overall building data and mapping relationship data in the MYSQL database;

[0060] In this embodiment, the building component data is stored in a mongoDB database, which is a non-relational database and storing the mapping relationship may cause distortion. The overall building data and the mapping relationship data are stored in a MYSQL database, which is a relational database and storing the mapping relationship can speed up the mapping relationship calculation.

[0061] Furthermore, the building component data in step 103 includes: building component entity data, building component identification data, and storing the building component data in the mongoDB database includes:

[0062] 1031. Store the building component identification data in a mongoDB database.

[0063] In step 1031, the building component data may include building component entity data and building component identification data. The building component entity data may be stored locally, while the identification may be stored in a mongoDB database, thereby reducing the amount of stored data and increasing the speed of calling out component data.

[0064] Furthermore, in step 103, the overall building data includes: overall building entity data, overall building identification data, and storing the overall building data and mapping relationship data in the MYSQL database includes:

[0065] 1032. Store the overall building identification data and mapping relationship data in the MYSQL database.

[0066] In step 1032, the overall building data includes overall building entity data and overall building identification data. The overall building data can be stored locally, and the identification storage and mapping relationship data can be stored in a MYSQL database.

[0067] 104. Transmit the mapping relationship data to the external port for retrieving the stored three-dimensional building data.

[0068] In this embodiment, the mapping relationship data is transmitted in the external port, and the mapping relationship data can be used as an identification symbol provided to the outside. When retrieving data, matching judgment is performed based on the retrieved data, and data is retrieved from the MYSQL database and the mongoDB database.

[0069] Furthermore, after step 104, the following steps may be performed:

[0070] 1041. Receive a reading instruction and analyze the overall building identification corresponding to the reading instruction;

[0071] 1042. In the MYSQL database, read the building overall data corresponding to the building overall identification, and read the mapping relationship data corresponding to the building overall data;

[0072] 1043. According to the mapping relationship data, the building component data corresponding to the overall building data is captured from the mongoDB database;

[0073] 1044. According to the mapping relationship data, the overall building data and the building component data corresponding to the overall building data are transmitted to the external port for viewing the three-dimensional building data.

[0074] In steps 1041-1044, the read instruction is an instruction that the external port needs to retrieve data. The read instruction determines the overall building identification, and retrieves the overall building data and mapping relationship data in the MYSQL database based on the overall building identification. Then, based on the mapping relationship data, the building component data is captured from the mongoDB database. The obtained data is transmitted to the external port to ensure that the external viewing is fast and accurate.

[0075] Furthermore, after step 104, the following steps may be performed:

[0076] 1045. Receive a component extension instruction, wherein the component extension instruction includes: component extension entity data;

[0077] 1046. Setting an identifier for component extension entity data, and encapsulating the component extension entity data into integral data to generate component extension data;

[0078] 1047. According to the component extension data, the overall building data and mapping relationship data are updated to obtain new overall building data and new mapping relationship data.

[0079] In steps 1045-1047, the extended instruction component has identification data, component entity data, and extended entity data, and an identification is set for the component extended data. Then the overall data is encapsulated to form the component extended data. The component extended data is added to the building overall data, and the mapping relationship is added to generate new building overall data and new mapping relationship data.

[0080] In the embodiment of the present invention, by saving the basic data of the entire inspection process of the drawing file in the service based on the original relational database and the non-relational database, the integrity of the drawing inspection process data is ensured, and the problem of incomplete three-dimensional drawing inspection process data is solved.
