However, in the prior art, the definition of data is limited to the industry basic standard, which is not conducive to the expansion of custom attributes. Moreover, there is no any auxiliary reference for the instantiation of components, resulting in low instantiation efficiency of components. SUMMARY

[0030] Embodiment one

[0031] Figure 1 A flowchart of a building data management method is provided for the first embodiment of the present application. This embodiment can be applied to the effective management of multi-source BIM data in a multi-source BIM data integration application scenario. The method can be executed by a building data management device, which can be realized in the form of hardware and / or software. Typically, the building data management device can be configured in an electronic device, such as a computer device or a server, etc. As shown in the figure, the method comprises: Figure 1

[0032] S110, obtaining multi-source building information model, and obtaining initial attribute data of each component according to the multi-source building information model.

[0033] In this embodiment, each component and the corresponding initial attribute data of each component can be extracted from the multi-source BIM. The initial attribute data corresponding to different components can be in the same format or different formats.

[0034] S120, standardizing each initial attribute data according to a preset data definition template, obtaining standard attribute data of each component, and obtaining memory layout corresponding to each component according to the standard attribute data.

[0035] ​The preset data definition template can be a standard data format of the component. Optionally, the preset data definition template can include component definition, attribute definition, attribute type definition, and / or attribute value definition. The attribute type includes basic type, array type, structure type (struct), and / or string type (string). The basic type can include integer type (int), single-precision floating point type (float), double-precision floating point type (double), and the like. In addition, the attribute type also supports mechanisms such as type nesting and inheritance. The attribute type is a data type of an attribute value. Through the preset data definition template, the needs of the business user for customizing and expanding the component can be met, so that the business user can quickly supplement and expand the integrated model.

[0036] In the embodiment, based on the preset data definition template, content data corresponding to each definition can be extracted from the initial attribute data of the component, to obtain attribute data corresponding to each attribute. For example, the attribute data can include attribute number, attribute type, attribute value, and attribute name. Then, the attribute data corresponding to each attribute can be combined to obtain standard attribute data of the component. Further, the memory layout corresponding to the component can be generated according to the attribute data corresponding to each attribute in the standard attribute data and a preset memory layout template.

[0037] For example, the memory layout template can include attribute type, attribute value, and memory offset. When generating the memory layout, the field values corresponding to each field can be extracted from the attribute data corresponding to each attribute, and the field values corresponding to each attribute can be combined to obtain the final memory layout.

[0038] Optionally, obtaining the memory layout corresponding to each component according to the standard attribute data can include:

[0039] According to the standard attribute data, obtaining attribute number, attribute name, attribute type, and attribute value corresponding to each attribute of each component, and according to the attribute type, obtaining memory offset corresponding to each attribute;

[0040] According to the attribute number, attribute name, attribute type, attribute value, and memory offset corresponding to each attribute, generating the memory layout corresponding to each component.

[0041] In an optional example, the flow of the memory layout generation method can be as follows Figure 2As shown, the left side is the standard attribute data, and the right side is the memory layout mapped from the standard attribute data. The memory layout includes an attribute number, an attribute type, an attribute value, a memory offset, and an attribute name field, each field corresponds to a column, and each attribute corresponds to a row. The memory offset is used to indicate the writing position of the attribute value in the instantiated object. For example, for the attribute key2, the corresponding memory offset is 4, indicating that the corresponding attribute value is written from the 5th byte.

[0042] It should be noted that the memory offset is related to the attribute type of the previous attribute, and the attribute type corresponds to the byte number one by one. In this embodiment, when obtaining the memory offset corresponding to the current attribute, first, the attribute types corresponding to the previous attributes are obtained, and the byte numbers corresponding to the previous attributes are obtained according to the correspondence between the attribute types and the byte numbers; then, the byte numbers corresponding to the previous attributes are added to obtain a sum value as the memory offset corresponding to the current attribute. Alternatively, the attribute type and the memory offset corresponding to the previous attribute can be obtained, and the byte number corresponding to the previous attribute can be obtained according to the correspondence between the attribute type and the byte number; then, the byte number corresponding to the previous attribute and the corresponding memory offset are added to obtain a sum value as the memory offset corresponding to the current attribute.

[0043] Specifically, first, the attribute number, attribute name, attribute type, and attribute value corresponding to each attribute are parsed from the standard attribute data; then, the memory offset corresponding to each attribute is obtained according to the attribute type corresponding to each attribute and the preset correspondence between the attribute type and the byte number; finally, a table can be generated as the memory layout according to the attribute number, attribute name, attribute type, attribute value, and memory offset corresponding to each attribute according to the format of the memory layout template.

[0044] The above setting has the benefit of efficiently obtaining the memory layout and providing data support for component instantiation.

[0045] S130, according to the memory layout corresponding to each of the components, generating an instantiated object corresponding to each of the components, and storing each of the instantiated objects to the local memory.

[0046] In this embodiment, based on the memory layout, a corresponding instance memory can be directly allocated to each attribute to quickly generate an instantiated object. Specifically, based on the memory offset in the memory layout corresponding to the component, a corresponding instance byte can be allocated to each attribute, and according to the attribute type in the memory layout, the attribute value or the memory address of the attribute value corresponding to the attribute can be written to the corresponding instance byte to obtain the instantiated object. Further, the instantiated object can be written to the local memory.

[0047] Optionally, generating the instantiation object corresponding to each component according to the memory layout corresponding to each component can comprise:

[0048] According to the memory layout corresponding to the current component, obtaining the attribute type, attribute value and memory offset corresponding to each attribute of the current component, and according to the attribute type, obtaining the layout type corresponding to each attribute of the current component;

[0049] According to the layout type, attribute value and memory offset corresponding to each attribute of the current component, generating the instantiation object corresponding to the current component.

[0050] In the embodiment, when instantiating the component, first, the attribute type, attribute value and memory offset corresponding to each attribute can be extracted from the memory layout corresponding to the component. Then, according to the attribute type corresponding to each attribute and the preset corresponding relationship between the attribute type and the layout type, the layout type corresponding to each attribute can be obtained. Further, according to the layout type corresponding to each attribute, the attribute value or the memory address of the attribute value can be written into the instantiation memory position corresponding to the memory offset, so as to obtain the instantiation object corresponding to the component.

[0051] The layout type can comprise a fixed memory layout and a dynamic memory layout. The fixed memory layout is a fixed attribute layout corresponding to a memory size, and the dynamic memory layout is an attribute layout corresponding to a dynamically changing memory size. The attribute type corresponding to the fixed memory layout is a basic type, and the attribute type corresponding to the dynamic memory layout comprises an array type, a structure type and a string type.

[0052] The above setting has the advantages of effectively improving the instantiation efficiency of the component and improving the retrieval and modification efficiency of the attribute.

[0053] Optionally, generating the instantiation object corresponding to the current component according to the layout type, attribute value and memory offset corresponding to each attribute of the current component can comprise:

[0054] According to the memory offset corresponding to the current attribute, obtaining the memory start position corresponding to the current attribute;

[0055] If the layout type corresponding to the current attribute is a fixed memory layout, determining that the value corresponding to the memory start position is the attribute value corresponding to the current attribute;

[0056] If the layout type corresponding to the current attribute is a dynamic memory layout, determining that the value corresponding to the memory start position is the memory address of the attribute value corresponding to the current attribute;

[0057] According to the value corresponding to each memory start position, generating the instantiation object corresponding to the current component.

[0058] In the embodiment, when instantiation is performed, for the attribute of the fixed memory layout, the corresponding attribute value is directly recorded, and for the attribute of the dynamic memory layout, the memory address of the corresponding attribute value is recorded instead of the specific attribute value. Specifically, first, the write start byte corresponding to the current attribute is determined as the memory start position according to the memory offset corresponding to the current attribute; then, if the layout type corresponding to the current attribute is the fixed memory layout, the attribute value is directly written from the memory start position, and if the layout type is the dynamic memory layout, the memory address of the attribute value is written from the memory start position. The memory address of the attribute value can be set in advance. After the writing of all attributes is completed, the instantiation object corresponding to the current component is obtained.

[0059] The above setting has the benefit that by storing only the attribute value or the memory address in the instantiation object, the memory consumption and the disk occupation are ensured to be small, and the utilization rate of the storage resource is improved.

[0060] The technical scheme of the embodiment of the application acquires a multi-source building information model, and acquires initial attribute data of each component according to the multi-source building information model; standardizes each initial attribute data according to a preset data definition template to acquire standard attribute data of each component, and acquires a memory layout corresponding to each component according to the standard attribute data; generates an instantiation object corresponding to each component according to the memory layout corresponding to each component, and stores each instantiation object in a local memory; through setting of a self-defined data definition template, convenient expansion of self-defined attributes of the multi-source BIM model can be realized, and through setting of the memory layout, instantiation of the component can be assisted, and the instantiation efficiency of the component can be improved.

[0061] Embodiment two

[0062] Figure 3 A flowchart of a building data management method provided by the embodiment two of the application, the embodiment is a further refinement of the above technical scheme, and the technical scheme in the embodiment can be combined with one or more of the above embodiments. As shown in the embodiment, the method comprises: Figure 3

[0063] S210, a multi-source building information model is acquired, and initial attribute data of each component is acquired according to the multi-source building information model.

[0064] S220, each initial attribute data is standardized according to a preset data definition template to acquire standard attribute data of each component, and according to the standard attribute data, an attribute number, an attribute name, an attribute type and an attribute value corresponding to each attribute of each component are acquired, and according to the attribute type, a memory offset corresponding to each attribute is acquired.

[0065] ​S230, generating the memory layout corresponding to each component according to the attribute number, attribute name, attribute type, attribute value and memory offset corresponding to each attribute, and obtaining the attribute type, attribute value and memory offset corresponding to each attribute of the current component according to the memory layout corresponding to the current component, and obtaining the layout type corresponding to each attribute of the current component according to the attribute type.

[0066] S240, obtaining the memory start position corresponding to the current attribute according to the memory offset corresponding to the current attribute.

[0067] S250, if the layout type corresponding to the current attribute is fixed memory layout, determining that the value corresponding to the memory start position is the attribute value corresponding to the current attribute; if the layout type corresponding to the current attribute is dynamic memory layout, determining that the value corresponding to the memory start position is the memory address of the attribute value corresponding to the current attribute.

[0068] S260, generating the instantiated object corresponding to the current component according to the value corresponding to each memory start position, and storing each instantiated object to the local memory.

[0069] In a specific example, the flow of the instantiation object generation method can be as shown in Figure 4 The attribute types corresponding to the attributes key1, key2 and key3 are int, float and double respectively, which are basic types, so the layout types corresponding to them are all fixed memory layout; while the attribute types corresponding to the attributes key4, key5 and key6 are struct, string and string respectively, so the layout types corresponding to them are dynamic memory layout. When generating the instantiated object, the writing of the attribute values is performed in the order of key1 to key6 according to the memory offset. Among them, for the fixed memory layout of key1, key2 and key3, the attribute values are directly written, and for the dynamic memory layout of key4, key5 and key6, the memory addresses of the attribute values are written instead of the specific attribute values.

[0070] S270, in response to the retrieval operation on the target attribute of the target component, obtaining the target memory layout and the target instantiated object corresponding to the target component, and obtaining the target memory offset and the target attribute type corresponding to the target attribute according to the target memory layout.

[0071] In this embodiment, when it is necessary to read the attribute value corresponding to the target attribute of the target component, the target memory layout and the target instantiated object corresponding to the target component can be first found from the local memory, and then the target memory layout is parsed to extract the target memory offset and the target attribute type corresponding to the target attribute.

[0072] S280, according to the target attribute type, if it is detected that the layout type corresponding to the target attribute is a fixed memory layout, the attribute value corresponding to the target attribute is directly obtained from the target instantiated object according to the target memory offset.

[0073] Specifically, first, the layout type corresponding to the target attribute is obtained according to the extracted target attribute type and the preset corresponding relationship between the attribute type and the layout type; then, if it is determined that the layout type is a fixed memory layout, the byte number corresponding to the target attribute is obtained according to the target attribute type and the preset corresponding relationship between the attribute type and the byte number, and the attribute value corresponding to the target attribute is extracted from the target instantiated object according to the target memory offset and the determined byte number.

[0074] S290, according to the target attribute type, if it is detected that the layout type corresponding to the target attribute is a dynamic memory layout, the target memory address is obtained from the target instantiated object according to the target memory offset, and the attribute value corresponding to the target attribute is obtained according to the target memory address.

[0075] In another case, if it is determined that the layout type corresponding to the target attribute is a dynamic memory layout, the target memory address corresponding to the attribute value can be extracted from the target instantiated object according to the target memory offset and the determined byte number, and the specific attribute value can be found in the local memory according to the target memory address. It should be noted that for the attribute of the dynamic memory layout, the target memory address can include the specific position and length of the attribute value in the structure or the string, so that the specific attribute value can be found according to the memory address.

[0076] Optionally, after generating the instantiated object corresponding to the component, the plurality of instantiated objects can be spliced and the spliced instantiated object can be serialized, for example, binary conversion, in response to the selection and integration operation of the user on the instantiated object, to obtain sequence data. Meanwhile, according to the byte length corresponding to each instantiated object, the byte offset corresponding to each instantiated object can be obtained. When it is necessary to retrieve the attribute value corresponding to the attribute of a certain component from the sequence data, the instantiated object can be found from the sequence data according to the byte offset corresponding to the instantiated object corresponding to the component, and the corresponding attribute value can be found from the instantiated object according to the memory layout corresponding to the component.

[0077] The embodiment realizes an extension method for a BIM model self-defined component, a user can define the component without coding, and rich BIM model information is expanded. Secondly, the embodiment manages the memory layout after the self-defined component is loaded into the memory, and is divided into fixed memory layout and dynamic memory layout, the memory layout can support the rapid instantiation of the self-defined component, and only the attribute value is stored in the instance, so that the small memory consumption and the disk occupation are ensured. Finally, based on the memory layout mechanism, the instance space size is directly allocated, and the attribute retrieval can be directly performed on the persistent binary block data generated after instantiation, since the memory layout records the clear memory layout information of the attribute value, so the retrieval efficiency is high. Overall, the embodiment designs a self-defined component template and the corresponding memory layout mechanism, greatly improves the instantiation efficiency, reduces the memory size of the generated instance, supports the rapid retrieval of the persistent binary block data, and meets the expansion demand and efficiency requirement of the self-defined component in the business.

[0078] The technical scheme of the embodiment of the application, after generating the instantiation object corresponding to the component and storing the instantiation object into the local memory, in response to the retrieval operation of the target attribute of the target component, the target memory layout and the target instantiation object corresponding to the target component are acquired, and the target memory offset and the target attribute type corresponding to the target attribute are acquired according to the target memory layout; according to the target attribute type, if it is detected that the layout type corresponding to the target attribute is the fixed memory layout, the attribute value corresponding to the target attribute is directly acquired from the target instantiation object according to the target memory offset; according to the target attribute type, if it is detected that the layout type corresponding to the target attribute is the dynamic memory layout, the target memory address is acquired from the target instantiation object according to the target memory offset, and the attribute value corresponding to the target attribute is acquired according to the target memory address; the direct or indirect retrieval of the attribute value is realized based on the memory layout, and the retrieval efficiency of the attribute value can be significantly improved.

[0079] It should be noted that the existing multi-source BIM model has the problems of component and attribute confusion or missing, which cannot be effectively utilized by subsequent business, so it is necessary for users to customize standard data types and attributes, quickly supplement and expand the integrated model, and ensure that the expanded model has a small storage volume, which can support the needs of efficient data retrieval, filtering and other needs of subsequent business. In view of the above problems and needs, the embodiment designs a general BIM component and attribute expansion framework, which can automatically parse a preset data definition template, generate a memory layout of a custom component based on the template file, and the memory layout includes the definition of various attribute types, including basic types (such as int, float, double, etc.), array types, string types, structures, etc., and supports nested definition of types, which can meet the expansion needs of custom components of business users. The memory layout includes two types, one is a fixed layout for immutable memory, for example, basic types, etc.; the other is a dynamic layout for variable memory, for example, array, structure, string, etc. Through this memory layout, the instantiation efficiency of custom components can be effectively improved, and the retrieval and modification efficiency of attributes can be improved.

[0080] Secondly, the embodiment proposes a data instantiation and retrieval mechanism based on the memory layout of the custom component. In the traditional BIM system supporting custom components and attributes, instantiating a custom component will clone a complete data based on the template, and in actual scenarios, the integrated BIM model has a large data size, and repeated cloning of each data will consume a large memory, and will also occupy a large disk when persisting, and the serialization and deserialization of data will consume a lot of time, and data retrieval must be performed on the deserialized data.

[0081] The embodiment instantiates based on the memory layout of the custom component, and the instantiated data only includes the attribute values of the custom component, without including the component definition, thereby ensuring a small memory consumption and disk occupation. The instantiation process includes instantiation of the fixed memory layout, which can directly allocate memory based on the memory layout to accommodate fixed-size attribute values, with extremely high efficiency; for dynamic memory layout, only a minimum data memory of the type needs to be generated during instantiation, and the attribute values can be dynamically expanded during editing. The embodiment also supports quick retrieval of attributes of the persisted data of the instantiated object. After generating the instantiated object based on the memory layout, the memory layout is still retained, and the direct retrieval of the attributes of the fixed memory layout and the indirect retrieval of the attributes of the dynamic memory layout can be realized based on the memory layout, without the need for deserialization of the binary data, which significantly improves the data retrieval efficiency, avoids all custom expansion data deserialization operations, and greatly reduces the memory occupation.
