Blockchains have decentralization, smart contracts, uniqueness, and non-tamper-resistance. At present, when the blockchain technology is combined to enable the sharing of BIM data to have higher credibility, safety and authority, for example, after one BIM data is modified, the whole modified BIM is subjected to uplink processing, full-quantity storage and multiple backups of the data of the modified model are required, and the rapid and effective transmission and use are not facilitated due to the huge volume of the BIM data, and in addition, the whole BIM cannot be put into the block for storage in one transaction due to the size limitation of each block of the blockchain.
In view of the foregoing, an embodiment of the present application provides a method and an apparatus for managing building information model BIM data, and the following detailed description of the embodiment of the present application is given with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is a schematic diagram of a building information model BIM data management system according to an embodiment of the present application, where the BIM data management system 100 may include: the system comprises a server and a blockchain network, wherein the server can be connected with the blockchain network and is used for issuing information to the blockchain network, a first database is arranged in the server and is used for storing building information model BIM data, when the server detects that the first database has data change, the server generates a corresponding log file for recording the data change, and then the log file is subjected to uplink processing and issued to the blockchain network.
Referring to fig. 2, fig. 2 is a flow chart of a method for managing building information model BIM data according to an embodiment of the present application, as shown in the drawings, the method for managing building information model BIM data includes the following operations:
S201, the electronic equipment establishes a first database, and the first database is used for storing BIM data;
In a specific implementation, the electronic device may be a server as shown in fig. 1, where the server may be configured as a cloud server, so that each participant in the BIM project may conveniently obtain and use BIM data stored in the first database to perform collaborative operation; when BIM data is stored, the BIM data can be stored in a database after being structured and disassembled, for example, the BIM data is disassembled into a plurality of pieces of data of the components, wherein the BIM data can also comprise a plurality of intermediate levels of data division, for example, the specific division basis can be set according to actual needs, for example, the data of different BIMs can be firstly distinguished, then, for a single BIM, the data of the floors can be divided into the data of the floors according to the floors, then, the data of the BIM model can be further divided, or the data of the BIM model can be divided into the data of pipelines, walls, hydropower and the like according to each subdivision field in the building industry, and finally, the BIM data are gradually disassembled to the component level.
S202, when the electronic equipment detects that the first database generates data fluctuation, generating a log file for recording the data fluctuation;
In a specific implementation, the content recorded in the log file may include at least one of the following information: the cause of the data fluctuation, information of the data fluctuation operator, the fluctuation time, identification information of the data generating the fluctuation, and data before the fluctuation of the data generating the fluctuation, of course, other information may be recorded according to actual needs, and is not limited herein. The data change cause information may be data change type information or an operation instruction for the data by the user, and if the operation instruction for the data in the database changes the data in the database by the user, the operation instruction may be recorded.
S203, the electronic equipment performs uplink processing on the log file so as to issue the log file into a blockchain network.
In a specific implementation, the log file may be processed in real time, for example, the database does not generate a log file for recording data change, and the log file is processed in a uplink manner and finally stored in the blockchain network, or the log file may be processed once every preset time interval, so as to obtain all log files for recording data change generated in the time interval, and perform the uplink processing in a unified manner.
It can be seen that in the embodiment of the present application, the electronic device first establishes a first database for storing BIM data, then generates a log file for recording the data change when detecting that the first database generates the data change, and then performs uplink processing on the log file to issue the log file to the blockchain network, so that it can be seen that the log file recording the data change of the database is issued to the blockchain network, that is, under the condition that the whole amount of the BIM data after the change is not uploaded to the blockchain, the change information of the database is stored in the blockchain network, which is favorable for reducing the data amount to be uplink while guaranteeing the sharing security of the BIM data.
In one possible example, in the first database, each BIM in the BIM data is disassembled to a component level to be stored, and data corresponding to each component includes: component geometry information and component pose information; the plurality of components with the same component geometric information in each BIM store one component geometric information; each of the plurality of components stores a piece of component pose information.
Wherein the component pose information is used to characterize the position and pose information of the component in the BIM.
In a specific implementation, since one BIM is composed of a plurality of components, when the BIM data is stored in the first database, the one BIM data can be disassembled into a plurality of component data for storage. In addition, since a building information model BIM generally has many components with the same geometric information, that is, the same geometric shape and size, but different positions and postures in the BIM, when storing, only one piece of geometric information can be stored together for a plurality of components with the same geometric information, and the respective pose information can be stored respectively, so that the storage of a plurality of identical geometric information in a database is not needed. For example, a BIM has 10 wall stud members with identical geometric information, only 1 part of geometric information is stored, and 10 wall stud members share 1 part of geometric information, and furthermore, each wall stud member stores one part of independent pose information without storing 10 parts of identical 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 a drawing of an engineering project, an examining staff examines problem description added to the component which is not compliant, and the like, and a designer of the BIM may modify according to the description information. When the description information of the problem is added for a component, the description information of the problem and the information of the component corresponding to the description information of the problem can be recorded in a corresponding log file, for example, each component has a component identifier uniquely associated with the component, and when the description information is added for a certain component, the generated log file comprises the component identifier of the component and the description information.
It can be seen that, in this example, for a plurality of members with the same member geometry information in each BIM, a part of member geometry information is stored, and each member stores a part 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: newly adding data, deleting data and modifying data; when the first database is detected to generate data fluctuation, generating a log file for recording the data fluctuation, wherein the log file comprises the following steps: when detecting that the first database generates data fluctuation, determining a data fluctuation type of the data fluctuation; acquiring related 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, the generated log file is used for recording the change, the specific condition of the data change can be known through the information recorded in the log file, and as the influence of different data change types on the data in the database is different, the information required to be recorded for explaining the specific condition of the data change is also different, and when the log file is generated, the information can be acquired by adopting different strategies according to the different data types and recorded in the log file.
In this example, when the first database generates the 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 the log file is generated according to the data change type and the acquired related information, so as to distinguish the related information acquisition policies of different data change types, thereby being beneficial to improving the flexibility of acquiring the related information.
In one possible example, the data change type is new data, and the acquiring the related information according to the information acquisition policy corresponding to the data change type includes: and acquiring component geometric information and component pose information in the newly added data.
In a specific implementation, since the newly added data is data which does not exist in the BIM data originally, all information of the newly added data, including the component geometry information and the component pose information, which need to be acquired when recording such data changes, can be clearly determined from the information recorded in the log file when needed, as to the state of the data stored in the database before the data changes occur. In addition, when the newly added data is stored in the database, if the newly added data has the same component geometry information as the original component geometry information in the data, the newly added component geometry information is not stored again, and the component corresponding to the component geometry information in the newly added data shares one piece of geometry information with the component of the geometry information in the database.
It can be seen that, in this example, when the data change type is newly added data, acquiring the related information includes acquiring the component geometry information and the component pose information 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 delete data, and the acquiring the related information according to the information acquisition policy corresponding to the data change type includes: and acquiring component geometric information and component pose information in the deleted data.
In a specific implementation, since deleting data deletes original existing data in the BIM, part of information in original BIM data is absent in changed BIM data, and for safety, all information of the deleted data including component geometric information and component position information can be recorded in a log file, and when necessary, the state of the data before change can be known according to related information in the log file, or the data can be recovered.
It can be seen that, in this example, when the data change type is deleted data, acquiring the related information includes acquiring the component geometry information and the component pose information 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 acquiring the related information according to the information acquisition policy corresponding to the data change type includes: determining first information of a change in the modified data, the first information including: component geometry information and/or component pose information; and acquiring the data before the first information changes.
In a specific implementation, since the data of the components before and after modification are recorded in the database, only the corresponding data is changed to a certain extent, when related information is acquired, only the changed information can be acquired, and no record is made for the information which is not changed, so that the information which is changed in the data needs to be determined first, then the data before the information is acquired, the record is made, and the data state before the modification can be definitely confirmed through a log file if necessary. In addition, for each component in each BIM stored in the first database, each component may be provided with a component number uniquely corresponding thereto, and data such as component geometry information and component pose information corresponding to each component are associated with the component number thereof, and acquiring the related information further includes: the component number corresponding to the modified data is acquired, and the component whose data has changed can be clarified by the component number.
In this example, when the data change type is modified data, the first information that changes in the modified data is determined first and then the data before the first information change is obtained, 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 has a geometric code uniquely corresponding thereto; the obtaining the component geometric information and the component pose information in the newly added data comprises the following steps: and acquiring the geometric coding and the component pose information of the newly added data.
In a specific implementation, the component geometric information in the database is stored in the blockchain, and a unique corresponding geometric code is set, that is, only one piece of different geometric information is newly added in the first database, the component geometric information in the newly added data is stored in the blockchain network, and the unique code is set, and when the data change occurs subsequently, if the component geometric information in the newly added data is the same as the geometric information stored in the database and the blockchain previously, the geometric code and the component pose information of the newly added data are recorded in the log file, and the geometric information is not required to be recorded again.
It can be seen that, in this example, each part of component geometry information in the first database is stored in the blockchain network, and each part of component geometry information has a geometry code uniquely corresponding to the component geometry information, and obtaining component geometry information and component pose information in the newly added data includes: and the geometric codes of the newly added data and the pose information of the components are acquired, so that the data quantity needing to be linked is reduced.
In one possible example, each piece of component geometry information in the first database is stored in the blockchain network, and has a geometric code uniquely corresponding thereto; the obtaining the component geometric information and the component pose information in the deleted data comprises the following steps: and acquiring the geometric codes and the component pose information of the deleted data.
When the data change occurs, if a plurality of members with the same geometric information are deleted for many times, the geometric information of the members is not required to be recorded in the log file each time, only the geometric codes are required to be recorded, the corresponding geometric information stored in the blockchain can be determined through the corresponding relation, namely, the data state before the change can be definitely determined through the geometric codes recorded in the log file, and the safety is ensured because the geometric information is stored in the blockchain.
It can be seen that, 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 piece of component geometry information, and the obtaining of component geometry information and component pose information in the deleted data includes: and the geometric codes of the deleted data and the pose information of the components are acquired, so that the data quantity needing to be linked is reduced.
In one possible example, each piece of component geometry information in the first database is stored in a blockchain network, and has a unique corresponding geometric encoding; the acquiring the data before the first information change includes: if the first information is component geometric information, acquiring geometric codes respectively corresponding to the component geometric information before the change; and if the first information is component pose information, acquiring component pose information before variation.
In a specific implementation, since each part of component geometric information is stored in the blockchain in advance, when data change occurs, if the first information which changes many times is the same component geometric information, the component geometric information is not required to be recorded in a log file for uploading to the blockchain many times, and the geometric information stored in the blockchain can be corresponding only by recording geometric codes.
It can be seen that, in this example, each part of component geometry information in the first database is stored in the blockchain network, and each part of component geometry information has a geometry code uniquely corresponding to the component geometry information, if the first information is component geometry information, the geometry codes respectively corresponding to the component geometry information before the change are obtained, and if the first information is component pose information, the component pose information before the change is obtained, which is favorable for reducing the data volume needing to be linked.
Embodiments of the present application are described below with reference to specific examples.
