Block chains have decentralization, intelligent contracts, uniqueness, and non-tamper-ability. At present, when the sharing of BIM data is more reliable, safe and authoritative by combining the block chain technology, for example, after one BIM data is modified, uplink processing is performed on the modified whole BIM, and the data of a modified model needs to be stored in full and backed up in multiple places.
In view of the foregoing problems, embodiments of the present application provide a method and a related apparatus for managing building information model BIM data, and the following describes embodiments of the present application in detail with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is an architecture diagram of a management system of building information model BIM data provided in an embodiment of the present application, and the management system 100 of BIM data may include: the server can be connected with the block chain network and issues information to the block chain network, a first database is arranged in the server and used for storing BIM data of a building information model, when the server detects that the first database has data change, a corresponding log file used for recording the data change can be generated, then uplink processing is carried out on the log file, and the log file is issued to the block chain network.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for managing building information model BIM data according to an embodiment of the present disclosure, where as shown in the figure, the method for managing building information model BIM data includes the following operations:
s201, the electronic equipment establishes a first database, wherein the first database is used for storing BIM data;
in a specific implementation, the electronic device may be the server shown in fig. 1, and the server may be configured as a cloud server, so that each participant in a BIM project can conveniently obtain and use the BIM data stored in the first database to perform cooperative work; when the BIM data is stored, the BIM data can be stored in a database after structured disassembly, for example, the data of one BIM is disassembled into the data of a plurality of members included in the BIM for storage, wherein the data of a plurality of intermediate levels can also be divided, for example, the specific division basis can be set according to actual needs, for example, the data of different BIMs are firstly distinguished, then, for a single BIM, the data of floors are divided according to floors, and then further divided, or the data in a BIM model is divided according to each subdivision field in the building industry, and divided into data of pipelines, walls, hydropower and the like, and finally, the data are gradually disassembled to the member level.
S202, when the electronic equipment detects that the first database generates data change, generating a log file for recording the data change;
in a specific implementation, the content recorded in the log file may include at least one of the following information: the data change factor, the data change operator information, the change time, the identification information of the changed data, the data before the changed data, and other information may be recorded according to actual needs, which is not limited herein. The data change reason information may be data change type information or an operation instruction of the user for the data, and if the operation instruction of the user for the data in the database causes the data in the database to change, the operation instruction may be recorded.
S203, the electronic equipment performs uplink processing on the log file so as to issue the log file to a block chain network.
In a specific implementation, the uplink processing on the log file may be performed in real time, for example, if the database does not generate a log file for recording data changes, the log file is uplink processed and is finally stored in the blockchain network, or the log uplink processing may be performed every preset time interval, so as to obtain all log files for recording data changes generated in the time interval, and perform uplink processing uniformly.
It can be seen that, in the embodiment of the present application, the electronic device first establishes the first database for storing the BIM data, and then generates a log file for recording data changes when detecting that the first database has data changes, and then performs uplink processing on the log file to issue the log file to the blockchain network, so that the log file in which the database data changes are recorded is issued to the blockchain network, that is, the change information of the database is stored in the blockchain network under the condition that the changed BIM data does not need to be uploaded to the blockchain in full, which is beneficial to reducing the amount of data to be uplinked while ensuring the BIM data sharing security.
In one possible example, in the first database, each BIM in the BIM data is disassembled to a component level for storage, and data corresponding to each component includes: member geometric information and member pose information; a plurality of components with the same component geometric information in each BIM store one piece of component geometric information; each of the plurality of members stores a copy of member pose information.
Wherein the member pose information is used for representing the position and the attitude information of the member in the BIM.
In a specific implementation, because one BIM is composed of a plurality of components, when the BIM data is stored in the first database, the BIM data can be disassembled into a plurality of component data for storage. However, because a plurality of components with the same geometric information, namely the same geometric shape and size, but different positions and postures in the BIM exist in one building information model BIM, during storage, only one piece of geometric information can be stored together for a plurality of components with the same geometric information, and then respective pose information is stored respectively, and the storage of a plurality of pieces of same geometric information in a database is not needed. For example, a BIM has 10 wall stud members with the same geometric information, and when storing, only 1 part of geometric information is stored, and 10 wall stud members share 1 part of the geometric information, and furthermore, each wall stud member stores one part of independent pose information without storing 10 parts of the same geometric information.
In addition, in a specific implementation, the data corresponding to the component may further include description information for the component, for example, in a process of examining drawings of an engineering project, a description of a problem added by a reviewer for examining an unqualified component, and the like, and a designer of the BIM may modify the description information. When the problem description information is added to a component, the problem description information and information of the component corresponding to the problem description information may be recorded in a corresponding log file, for example, each component has a component identifier uniquely associated therewith, and when the description information is added to a certain component, a generated log file includes the component identifier of the component and the description information.
As can be seen, in this example, for a plurality of members with the same member geometry information in each BIM, one piece of member geometry information is stored, and each member stores one piece of member pose information, which is beneficial to reducing the storage space of the BIM file.
In one possible example, the data change type of the data change includes: adding data, deleting data and modifying data; when the data change of the first database is detected, generating a log file for recording the data change, wherein the log file comprises: when detecting that the first database generates data change, determining the data change type of the data change; acquiring relevant information according to an information acquisition strategy corresponding to the data change type; and generating the log file according to the data change type and the related information.
In a specific implementation, an operator may change data stored in a database by operating the data, a generated log file is used to record the change, and the specific situation of the data change can be known through information recorded in the log file.
It can be seen that, in this example, when it is detected that the first database has data change, the data change type of the data change is determined, then the related information of the data change is acquired according to the information acquisition policy corresponding to the data change type, and finally a log file is generated according to the data change type and the acquired related information.
In one possible example, the obtaining of the relevant information according to the information obtaining policy corresponding to the data change type includes: and acquiring the geometric information and pose information of the member in the newly added data.
In the concrete implementation, because the newly added data is data which does not exist in the BIM data originally, when the data change is recorded, all information of the newly added data, including the geometric information and the pose information of the member, which needs to be acquired, can be used for determining the state of the data stored in the database before the data change occurs through the information recorded in the log file when needed. In addition, when the newly added data is stored in the database, if the newly added data has the same component geometric information as the original component geometric information in the data, the newly added component geometric information is not stored again, and the component corresponding to the component geometric information in the newly added data shares one piece of geometric information with the component of the geometric information in the database.
Therefore, in this example, when the data change type is the newly added data, the obtaining of the relevant information includes obtaining of the geometric information and the pose information of the member in the newly added data, which is beneficial to improving the security of BIM data sharing.
In one possible example, the data change type is deletion data, and the obtaining related information according to an information obtaining policy corresponding to the data change type includes: and acquiring the member geometric information and the member pose information in the deleted data.
In specific implementation, due to the fact that the deleted data can delete the original existing data in the BIM, partial information in the original BIM data is absent in the changed BIM data, and in view of safety, all information of the deleted data, including component geometric information and component position information, can be recorded in the log file, and when necessary, the state of the data before change can be known or the data can be restored according to the related information in the log file.
As can be seen, in this example, when the data change type is deletion data, acquiring the related information includes acquiring geometric information and pose information of a component in the deleted data, which is beneficial to improving the security of BIM data sharing.
In one possible example, the data change type is modified data, and the obtaining related information according to an information obtaining policy corresponding to the data change type includes: determining first information that produces a change in the modified data, the first information comprising: member geometry information and/or member pose information; and acquiring data before the first information is changed.
In the concrete implementation, the data of the component before and after modification is recorded in the database, and only the corresponding data is changed to a certain extent, so that when the relevant information is acquired, only the changed information can be acquired, and the information which is not changed can not be recorded, so that the information which is changed in the data needs to be determined firstly, then the data before the information is changed is acquired and recorded, and then if needed, the data state before modification can be determined through the log file. In addition, for the member in each BIM stored in the first database, each member may be provided with a member number uniquely corresponding thereto, and the data corresponding to each member, such as member geometric information and member pose information, are associated with the member number thereof, and acquiring the related information further includes: and acquiring the component number corresponding to the modified data, and identifying the component with data change according to the component number.
In this example, when the data change type is modified data and related information is acquired, the first information that is changed in the modified data is determined first, and then the data before the first information is changed is acquired, which is beneficial to improving the security of BIM data sharing.
In one possible example, each piece of component geometry information in the first database is stored in the blockchain network, and each piece of component geometry information has a geometry code uniquely corresponding to the piece of component geometry information; the acquiring of the geometric information and pose information of the member in the newly added data includes: and acquiring the geometric code and member pose information of the newly added data.
In the concrete implementation, the geometric information of the members in the database is stored in the block chain, and a unique corresponding geometric code is set, that is, as long as a different piece of geometric information is added in the first database, the geometric information is stored in the block chain network and the unique code is set, when data change occurs subsequently, if the geometric information of the members in the added data is the same as the geometric information previously stored in the database and the block chain, the geometric code and the member pose information of the added data are only required to be recorded in the log file, and the geometric information is not required to be recorded again.
As can be seen, in this example, each piece of component geometric information in the first database is stored in the blockchain network, and each piece of component geometric information has a geometric code uniquely corresponding to the component geometric information, and acquiring the component geometric information and the component pose information in the newly added data includes: and the geometric code and the member pose information of the newly added data are acquired, so that the data volume needing to be linked up is favorably reduced.
In one possible example, each piece of component geometry information in the first database is stored in the blockchain network, and each piece of component geometry information has a geometry code uniquely corresponding to the piece of component geometry information; the acquiring of the component geometric information and the component pose information in the deleted data includes: and acquiring the geometric coding and member pose information of the deleted data.
The geometric information of each component is pre-stored in the block chain, so that when data change occurs, if a plurality of components with the same geometric information are deleted for a plurality of times, the geometric information of the components does not need to be recorded in a log file every time, only geometric codes need to be recorded, the corresponding geometric information stored in the block chain can be determined through the corresponding relation, namely the data state before change can be determined through the geometric codes recorded in the log file, and the security is also guaranteed because the geometric information is stored in the block chain.
As can be seen, in this example, each piece of component geometry information in the first database is stored in the blockchain network, and each piece of component geometry information has a geometry code uniquely corresponding to the component geometry information, and the acquiring of the component geometry information and the component pose information in the deleted data includes: and acquiring the geometric code and member pose information of the deleted data, so that the quantity of data needing to be linked up is reduced.
In one possible example, each piece of component geometry information in the first database is stored in a blockchain network, and each piece of component geometry information has a geometry code uniquely corresponding thereto; the acquiring data before the first information change includes: if the first information is the component geometric information, acquiring geometric codes corresponding to the component geometric information before change respectively; and if the first information is the member pose information, acquiring the member pose information before the change.
In the specific implementation, each piece of component geometric information is pre-stored in the block chain, and when data change occurs, if the first information which changes for many times is the same component geometric information, the component geometric information does not need to be recorded in a log file and transmitted to the block chain for many times, and only geometric codes need to be recorded, so that the geometric information stored in the block chain can be corresponded to.
As can be seen, in this example, each piece of component geometric information in the first database is stored in the blockchain network, and each piece of component geometric information has a geometric code uniquely corresponding thereto, if the first information is the component geometric information, the geometric codes respectively corresponding to the component geometric information before change are obtained, and if the first information is the component pose information, the component pose information before change is obtained, which is beneficial to reducing the amount of data that needs to be linked.
The embodiments of the present application will be described below with reference to specific examples.
Take the example that A building company accepts the engineering project of the rest homes, and three BCD drawing examination organizations are respectively responsible for examining the foundation, the main structure, the electricity and the drainage. A company A builds BIM of a nursing home engineering project, divides the BIM according to examination projects, stores the BIM into a first database, authorizes three BCD companies to look up and modify data of corresponding parts respectively, obtains authorized data of the three BCD companies, conducts picture examination operation, stores picture examination results into corresponding BIM data in the first database, modifies the BIM according to the picture examination results, updates the BIM data in the first database, and examines the updated BIM again until the qualified BIM is determined.
