Technical Field

[0001] The present invention relates to the field of building information models, and in particular to a standard conversion method, device, equipment and storage medium for building information models. Background Art

[0002] As a new tool in architecture, engineering and civil engineering, building information modeling is mainly used to establish a virtual three-dimensional model for the target project in order to fully display the target project information consistent with the actual situation to the user.

[0003] In the prior art, it is usually necessary to first obtain the original standard file followed by the building information model to be converted and the target standard file corresponding to the original standard file, and convert the building information model to be converted based on the original standard file into a standard building information model following the target standard file according to the correspondence between the original standard file and the target standard file. Among them, the standard file can be used to define the name and attribute information of each device in the building information model.

[0004] However, the existing technology of converting standards based on the correspondence between standard files requires knowing the detailed contents of both standard files at the same time, which makes the conversion more complicated and less efficient. Secondly, since the original standard file and the target standard file do not necessarily correspond completely, it is difficult to fully match the two standard files. Summary of the invention

[0005] The present invention provides a method, device, equipment and storage medium for converting the standards of a building information model, which can improve the efficiency and accuracy of converting the standards of a building information model.

[0014] Optionally, each instantiated device under the first original device type is renamed according to the target device type that matches the first original device type, including: renaming each instantiated device under the first original device type according to the target device type and attribute information that matches the first original device type; and each instantiated device under the second original device type is renamed according to the target device type that matches the second original device type, including: renaming each instantiated device under the second original device type according to the target device type and attribute information that matches the second original device type.

[0015] Optionally, each instantiated device under the first original device type is renamed according to the target device type that matches the first original device type, including: determining a first target device name corresponding to each instantiated device under the first original device type according to the target device type that matches the first original device type; replacing each instantiated device under the first original device type according to a pre-built first target device named as the first target device name; and renaming each instantiated device under the second original device type according to the target device type that matches the second original device type, including: determining a second target device name corresponding to each instantiated device under the second original device type according to the target device type that matches the second original device type; and replacing each instantiated device under the second original device type according to a pre-built second target device named as the second target device name.

[0016] Optionally, after obtaining the standard building information model corresponding to the building information model to be converted, it also includes: obtaining the professional type to which each instantiated device contained in the standard building information model belongs, and screening out target instantiated devices of non-set professional types among each instantiated device; eliminating the target instantiated devices in the standard building information model to obtain the target building information model.

[0017] In a second aspect, an embodiment of the present invention further provides a standard conversion device for a building information model, the device comprising:

[0033] Embodiment 1

[0034] Figure 1 1 is a flowchart of a standard conversion method for a building information model provided according to a first embodiment of the present invention. This embodiment is applicable to the case of converting building information models that comply with different standards into building information models that comply with a unified standard. The method can be executed by a standard conversion device for a building information model. The standard conversion device for a building information model can be implemented in the form of hardware and / or software. The standard conversion device for a building information model can be configured in an electronic device such as a computer.

[0035] like Figure 1 As shown, the standard conversion method of a building information model disclosed in this embodiment includes:

[0036] S110: Acquire each building information model to be converted and an instantiated device in each building information model to be converted.

[0037] In this embodiment, the building information model to be converted may be a three-dimensional model for reflecting all building information of the target object. There may be multiple target objects, such as a whole building and a floor in the whole building. The instantiated device may be an instantiated device in the building information model to be converted.

[0038] In this step, specifically, after batch acquiring each to-be-converted building information model for reflecting the actual situation of the current building, the instantiated devices in each to-be-converted building information model and the original device name of each instantiated device can be acquired.

[0039] S120 . Obtain different original device types according to the original device name of each instantiated device.

[0040] In this embodiment, the original device name at least includes the original device type and the instantiation number of each instantiated device.

[0041] In this step, specifically, the original device type of each instantiated device can be obtained according to the original device name of each instantiated device. Then, each original device type can be deduplicated to obtain different original device types.

[0042] S130: According to the number of candidate device types corresponding to the original device type, configure a target device type or a standard conversion rule that matches the original device type.

[0043] In this step, specifically, artificial intelligence technology such as keyword recognition method can be used to obtain candidate device types corresponding to each original device type, and the target device type or standard conversion rule corresponding to each original device type can be determined according to the number of candidate device types.

[0044] S140: Perform standard conversion on the instantiated devices under each original device type according to the target device type or standard conversion rule respectively matched with each original device type, so as to obtain a standard building information model corresponding to the building information model to be converted.

[0045] In this step, specifically, in response to a standard conversion instruction triggered by a user, the instantiated devices under each original device type may be renamed according to the target device type or standard conversion rule respectively matched with each original device type, so as to obtain a standard building information model corresponding to the building information model to be converted.

[0046] The technical solution of this embodiment obtains each building information model to be converted, and the instantiated devices in each building information model to be converted; obtains different original device types according to the original device name of each instantiated device; configures the target device type or standard conversion rule matching the original device type according to the number of candidate device types corresponding to the original device type; performs standard conversion on the instantiated devices under each original device type according to the target device type or standard conversion rule respectively matching each original device type, and obtains the technical means of the standard building information model corresponding to the building information model to be converted. This solves the problem that the existing technology of performing standard conversion according to the correspondence between standard files requires understanding the detailed contents of two standard files at the same time, resulting in low standard conversion efficiency. Building information models that follow different standards can be converted into building information models that follow a unified standard without understanding the original standard files, thereby improving the efficiency of converting the standards of building information models.

[0047] Embodiment 2

[0048] Figure 2 It is a flowchart of another standard conversion method of a building information model provided according to the second embodiment of the present invention. This embodiment is based on the further optimization and expansion of the above embodiments and can be combined with various optional technical solutions in the above implementation methods.

[0049] like Figure 2 As shown, the standard conversion method of a building information model disclosed in this embodiment includes:

[0050] S210: Acquire original building information models, and merge the original building information models belonging to the same floor to obtain a building information model to be converted.

[0051] In this embodiment, the types of the original building information model may be various, such as architecture, structure, water supply and drainage, HVAC and electricity.

[0052] In this step, specifically, according to the correspondence between the original building information models and the floors, the original building information models belonging to the same floor can be obtained, and the original building information models belonging to the same floor can be merged to obtain the building information model to be converted.

[0053] For example, assuming that there is a two-story building, and the first floor corresponds to a structural information model and a water supply and drainage information model, and the second floor corresponds to a building information model, a structural information model, a water supply and drainage information model, a HVAC information model, and an electrical information model, then the structural information model and the water supply and drainage information model belonging to the first floor can be merged to obtain the building information model to be converted corresponding to the first floor. The building information model, structural information model, water supply and drainage information model, HVAC information model, and electrical information model belonging to the second floor can be merged to obtain the building information model to be converted corresponding to the second floor.

[0054] The advantage of such a setting is that, compared with the existing technology of manually copying each original building information model to the building information model to be converted one by one, the technical solution of this embodiment establishes a correspondence between the original building information model and the floor, and merges the original building information models belonging to the same floor according to the above correspondence to obtain the building information model to be converted. The technical means improves the generation efficiency of the building information model to be converted, thereby improving the efficiency of converting the standard of the building information model.

[0055] S220 . Obtain different original device types according to the original device name of each instantiated device.

[0056] S230: When the candidate device type that matches the original device type is unique, use the candidate device type as the target device type that matches the original device type.

[0057] Exemplarily, assuming that the original device type is a fan, and the only candidate device type that matches the original device type is a supplementary fan, the supplementary fan can be used as the target device type that matches the fan.

[0058] S240: Use the original device type that matches the target device type as the first original device type, and rename each instantiated device under the first original device type according to the target device type that matches the first original device type.

[0059] In this step, specifically, the first target device name corresponding to each instantiated device under the first original device type can be determined based on the target device type that matches the first original device type and the unique identification code of the target device type. Alternatively, the first target device name corresponding to each instantiated device under the first original device type can be determined based on the target device type that matches the first original device type and the attribute information. The attribute type may include device material and thickness, etc. Alternatively, the first target device name corresponding to each instantiated device under the first original device type can be determined based on the target device type that matches the first original device type, the attribute information, and the unique identification code of the target device type.

[0060] Then, each instantiated device under the first original device type can be directly renamed to the matching first target device name. Alternatively, the first target device name corresponding to each instantiated device under the first original device type can be determined according to the target device type matching the first original device type, and each instantiated device under the first original device type can be replaced according to the pre-built first target device named as the first target device name.

[0061] Exemplarily, if the first original device type is a supporting wall, the first target device name that matches each instantiated device under the first original device type can be determined based on the target device type that matches the supporting wall and the unique identification code of the target device type, and each instantiated device under the first original device type can be directly renamed to the matching first target device name.

[0062] The advantage of such a setting is that, compared with the existing technology of directly constructing a standard building information model according to the target standard file, the technical solution of this embodiment fully utilizes the devices in the building information model to be converted and the relationship between the devices by directly renaming each instantiated device under the first original device type to a matching target device name, thereby reducing the construction cost of the standard building information model.

[0063] S250: When there are multiple candidate device types that match the original device type, configure a standard conversion rule that matches the original device type, and select one from each candidate device type as a target device type that matches the original device type according to the standard conversion rule.

[0064] In this step, specifically, when there are multiple candidate device types that match the original device type, characteristic information that can be used to select the target device type can be determined in the building information model to be converted based on each candidate device type, and a standard conversion rule that matches the original device type can be configured based on the characteristic information.

[0065] Exemplarily, if the original device type of the instantiated device is an axial flow fan, and the candidate device types corresponding to the axial flow fan include ventilation fans, fire supply air fans, and mechanical smoke exhaust fans, the standard conversion rule can be determined as determining the target device type that matches the axial flow fan according to the pipeline type.

[0066] S260: taking the original equipment type that matches the standard conversion rule as the second original equipment type, and identifying characteristic information in the building information model to be converted according to the standard conversion rule.

[0067] Continuing with the above example, assuming that the standard conversion rule is to determine the target device type that matches the axial fan according to the pipe type, the pipe type in the building information model to be converted can be identified.

[0068] S270: Select one from the candidate device types corresponding to the second original device type according to the feature information as a target device type matching the second original device type.

[0069] Continuing with the above example, if the pipe type in the building information model to be converted is a smoke exhaust duct, it can be determined that the target equipment type matching the second original equipment type is a smoke exhaust fan. In this case, the axial flow fan can be renamed as a mechanical smoke exhaust fan.

[0070] S280: Rename each instantiated device under the second original device type according to the target device type matching the second original device type.

[0071] In this step, specifically, the second target device name corresponding to each instantiated device under the second original device type can be determined based on the target device type that matches the second original device type and the unique identification code of the target device type. Alternatively, the second target device name corresponding to each instantiated device under the second original device type can be determined based on the target device type that matches the second original device type and the attribute information. Alternatively, the second target device name corresponding to each instantiated device under the second original device type can be determined based on the target device type that matches the second original device type, the attribute information, and the unique identification code of the target device type.

[0072] Then, each instantiated device under the second original device type can be directly renamed to a matching second target device name. Alternatively, the second target device name corresponding to each instantiated device under the second original device type can be determined according to the target device type matching the second original device type, and each instantiated device under the second original device type can be replaced according to the pre-built second target device named as the second target device name.

[0073] Optionally, after renaming each instantiated device under each original device type to obtain a standard building information model corresponding to the building information model to be converted, the method further includes: obtaining the professional type to which each instantiated device contained in the standard building information model belongs, and filtering target instantiated devices of non-set professional types among each instantiated device; and eliminating the target instantiated devices in the standard building information model to obtain the target building information model. There may be multiple professional types to which the instantiated devices belong, such as civil engineering, water supply and drainage, HVAC, and electrical. The set type may be one or more of the device types.

[0074] Specifically, at least one of the professional types can be used as a set type, and target instantiation devices of non-set types of the corresponding professional type can be screened out in each instantiation device, and the target instantiation devices in the standard building information model can be eliminated to obtain a target building information model.

[0075] Exemplarily, assuming that the set type is civil engineering, target instantiated devices of professional types other than civil engineering can be screened out from each instantiated device, and the target instantiated devices in the standard building information model can be eliminated to obtain a target building information model.

[0076] The advantage of this setting is that by eliminating the target instantiated devices in the standard building information model, only the instantiated devices with the set professional type can be retained, effectively adapting to the needs of different users.

[0077] Optionally, in response to a thumbnail instruction triggered by the user for the standard building information model, a thumbnail of the standard building information model may be displayed to the user so that the user can see the complete standard building information model.

[0078] Optionally, in response to a user's selection instruction for an instantiated device in the standard building information model, a standard conversion interface for the instantiated device may be displayed to the user. In response to the user configuring a target device type for the instantiated device in the standard conversion interface, the standard building information model may be updated.

[0079] The technical solution of this embodiment improves the efficiency of generating the building information model to be converted, thereby improving the efficiency of converting the standard of the building information model, by establishing a corresponding relationship between the original building information model and the floor, and merging the original building information models belonging to the same floor according to the above corresponding relationship to obtain the building information model to be converted. Secondly, by configuring the standard conversion rules that match the original equipment type when there are multiple candidate equipment types that match the original equipment type, the target equipment type corresponding to the original equipment type can still be accurately determined when the relationship between the original equipment type and the candidate equipment type is one-to-many, thereby improving the accuracy of converting the standard of the building information model. Finally, by fully automating the operation of converting the model standard, the accuracy of converting the standard of the building information model is improved while simplifying the operation and increasing the applicability.

[0087] The technical solution in this embodiment solves the problem of low efficiency of standard conversion caused by the need to simultaneously understand the detailed contents of two standard files in the prior art of standard conversion according to the correspondence between standard files, through the mutual cooperation of the instantiated device acquisition module, the original type determination module, the conversion standard configuration module and the standard conversion module. It can convert building information models that comply with different standards into building information models that comply with unified standards without understanding the original standard files, thereby improving the efficiency of converting the standards of building information models.
