Fig. 2 is a schematic flow chart of a data layering method based on a building information model according to an embodiment of the present application, and specifically includes the following steps:
The target building information model data can be any BIM model file, the uploaded BIM model file can be received through an online platform, the online platform can be carried on a server, and a user can log in the online platform through a webpage, a client and the like, upload the BIM model file and perform related operations, which is not described in detail herein.
By acquiring the target building information model data, a user can conveniently upload the BIM model file, preparation can be made for subsequent data layering, and the accuracy of data layering is improved.
The data types may include metadata, intermediate data, application data, and service data. The metadata comprises raw data of the target building information model data store; the intermediate data represents data that is required as an intermediate medium to perform a first operation based on the metadata; the application data represents data serving a functional application generated in a second operation; the service data represents data generated by combining any one or any combination of the metadata, the intermediate data and the application data with a preset service.
Specifically, the metadata represents the most original data in the target building information model data, for example, the most original data may be the original data stored in the BIM model;
the intermediate data is data that is used as an intermediate medium when a predetermined operation is to be performed based on the metadata, and for example, data of a volume surrounding each member to be used when a weight reduction process is to be performed;
the application data refers to data generated in a specific logical operation process and serving specific functional applications, such as lightweight model packet data;
the service data refers to service-related data generated when data based on the above layers is combined with a specific service, such as a state of a parking space.
By determining the data types included in the target building information model data, the data of different data types can be conveniently stored to different levels, and the data types are divided according to the data functions, so that the data can be conveniently checked and used by a user.
And 203, dividing the target building information model data into preset levels according to the data types and storing the preset levels.
The preset hierarchy comprises a metadata layer, a middle data layer, an application data layer and a service data layer; the metadata can be divided into metadata layers for storage; dividing the intermediate data into intermediate data layers for storage; dividing the application data into application data layers for storage; and dividing the service data into the service data layer for storage.
Next, a hierarchical relationship in the embodiment of the present application is described with reference to fig. 3, where fig. 3 is a schematic diagram of a hierarchical relationship provided in the embodiment of the present application, and it can be seen that a bottom layer is metadata, and an intermediate data layer, an application data layer, and a service data layer are sequentially arranged on the metadata. The upper layer data can refer to the bottom layer data and can be referred by layers; but the underlying data cannot reference the upper layer data to ensure loose coupling of the data. Specifically, the service data layer may refer to an application data layer, an intermediate data layer, and a metadata layer; the application data layer may reference an intermediate data layer and a metadata layer; the intermediate data layer may reference a metadata layer; the metadata layer cannot reference other layers.
The target building information model data are divided into preset levels according to the data types and stored, the data are layered according to the data of different levels, and the data of each layer have respective special functions, so that the data of different layers are loosely coupled, and the subsequent business and the requirement can be conveniently expanded. For example, after the lightweight algorithm is improved, the original data which is put in storage does not need to be reintroduced, and the lightweight processing can be directly carried out again based on the existing metadata, so that the lightweight algorithm is not sensible to users. For another example, no matter how the data of the business layer changes, the data of the bottom layer is not affected.
Therefore, by the method, firstly, target building information model data are obtained; then, determining the data type included in the target building information model data; and finally, dividing the target building information model data into preset levels according to the data types and storing the preset levels. By layering the building information model data, the data of each layer has respective functions, so that the data coupling degree between different layers is low, and the expansion of subsequent services and requirements is facilitated.
