Technical Field

[0001] The present invention relates to the field of data processing, and in particular to a BIM-based project information management method and system. Background Art

[0002] In existing construction projects, it is necessary to integrate the information of all parties and establish communication channels between all parties in order to achieve the required information communication and sharing. However, due to the many inconveniences in communication of existing technologies, the lack of popularization of programmatic modeling, and the limited sharing of models and data terminals, it is difficult to effectively communicate a lot of information. At present, a virtual three-dimensional model of a construction project can be established through BIM, and digital technology can be used to provide a complete construction project information database that is consistent with the actual situation for this model. However, due to errors and omissions in data acquisition during use, the accuracy of the BIM model is relatively low, which affects subsequent use. Summary of the invention

[0014] Preferably, when downloading project data in the BIM storage space, the BIM server will generate a one-time extraction code, and the BIM server will remove the encryption and allow the storage data to be downloaded based on the verification information of the extraction code.

[0015] Preferably, the data downloaded through the extraction code directly downloads the unintegrated information in the BIM server, or extracts the integrated BIM model file or splits out the project information within the authority scope for downloading, and outputs text data in a standard format or a set format for the corresponding project information.

[0016] Preferably, after the establishment of the BIM server is completed, the search and / or stripping and / or downloading operations of the preset project data are performed through a fixed loop, and after repeating the operation 3 to 10 times, the operation is stopped after verifying that the operations performed and the project data are correct.

[0040] Embodiment 1

[0041] Please refer to Figure 1 As shown, this implementation provides a BIM-based project information management method, including the following steps:

[0042] S101. After logging into the BIM server client for the first time, register the user information, and the user information storage space stores the registered user information.

[0043] When using for the first time, you need to register your user information, enter your personal identity information, login account information, login password information, and project identity information, and store this information in the user information storage space. If you need to log in later, you only need to use the login account information and login password information to log in to the BIM server and perform the corresponding operations.

[0044] Furthermore, the registered information may be changed or corrected to replace the account owner or to correct the stored information.

[0045] When you need to log in again to access the BIM storage space, you need to call and approve the user information in the user information storage space. If the identity information is the same, access is allowed; if the identity information is different, it stays in the login state and prompts that access is prohibited. At this time, you can re-enter the correct login account information and login password information to log in. If the information entered is wrong for multiple times (for example, 3-8 times, preferably 5 times), the user will be locked out, and you need to contact the backend staff or the administrator of the BIM server to verify the information and unlock it to ensure the user's safety.

[0046] S102: Edit or upload the project information to be processed to the user information storage space.

[0047] After logging into the BIM server, you can classify the data, such as models, drawings, contracts, construction issues, supply lists, etc. You can also upload texts in different formats as needed, such as CGR, IFC, DWG, STP, RVT, JPG or PDF, etc. In this way, the project information can be edited and uploaded as needed.

[0048] S103. The project information uploaded by multiple users is sorted and classified by the data processing center, and stored in the BIM storage space.

[0049] This can create an effect where multiple users can log in and use the system at the same time. Taking the construction industry as an example, users are divided into: owners, designers, construction workers, supervisors and suppliers, so that users with different identities can use the system.

[0050] When the project information is transmitted to the data processing center, it will first be cached through the big data cache center. The BIM server uses Python open source to input codes such as Instruction Code and Machine Code, and completes the processing of codes such as Program Number, Program Name, and Block in Revit's open source. Then, the Machine Program is processed in the automatic processing control system, and the data is sorted and classified on the appropriate medium according to the instruction sequence written in the automatic control language and format, and finally allocated to the corresponding folder for retrieval. The corresponding folder is stored in the BIM storage space.

[0051] After the completed project information is stored in the BIM storage space, the project information is encrypted and fed back to the user terminal that logged in and uploaded it, or to the user's personal terminal bound to the BIM server.

[0052] For Revit's open source platform, Dynamo plug-ins can be used for docking. For example, when the memory data processing center (MRH-R; full name: Memory Repeater Hub), the data processing center (MRH-S; full name: SDRAM Repeater HubSDRAM) or the memory data conversion center (MTH; full name: Memory Transfer Hub) are running normally, it can be ensured that each data can be correctly returned to its place through the BIM server. For example, the unit price of the component and the supplier information can be correctly attached to the component itself; and before the extraction code is obtained, the project information is in an encrypted state.

[0053] S104: Integrate the project information in the BIM storage space and edit and generate a BIM model file. The data processing center updates or supplements the multiple uploads by the user, completes the update and / or improvement of the BIM model file, and establishes a BIM model database.

[0054] The BIM model file is generated through the integrated project information, and can also be updated or supplemented through the subsequent uploaded project information to improve the BIM model file. In this way, the accuracy of the BIM model file can be guaranteed by updating and improving the data for use.

[0055] Specifically, for duplicate uploaded data, there will be steps of verification, screening out differences and replacement, that is, checking whether the two pieces of data are duplicate uploaded data, and then finding out the difference information through file comparison, or manually entering the difference information; finally, the data is replaced, and the BIM model file is re-established with the replaced data to complete the update. The query of the difference information can achieve the effect of quickly updating the BIM model file and ensure the accuracy of the data.

[0056] At the same time, the BIM model file can also be stored to establish a BIM model database, so that when it is used later, the previous BIM model file can be called or queried by accessing the BIM model database.

[0057] In the method of this embodiment, there is also a platform for users to communicate with each other in the user information storage space, and / or a communication platform for leaving messages and replying to communication information. For example, APP software for communication (such as existing WeChat, QQ, enterprise WeChat or DingTalk, etc.) can also be used for communication through email.

[0058] When downloading project data in the BIM storage space in the method of this embodiment, the BIM server will generate a one-time extraction code (the extraction code can be a QR code extraction code, a bar pattern extraction code, or a character password extraction code, etc.), and the BIM server will remove the encryption and allow the stored data to be downloaded based on the verification information of the extraction code.

[0059] Specifically, if you need to submit the required project information, you first log in to your own user account (such as the owner), and after communicating with the party who needs the information (such as the designer), you can obtain the extraction code from the designer, and then obtain the project information stored in the BIM storage space by the designer. This extraction code is generated by the account owner through the background programming software, and can only be copied and verified in the background once. The Planning Sheet is input in the background through the digital separation verification mode, and the two-dimensional extraction code is automatically generated through the Subprogram. You only need to scan the code with the platform's external camera to obtain the corresponding information output by the background.

[0060] Furthermore, the data downloaded by extracting the code can directly download the unintegrated information in the BIM server, or the integrated BIM model file can be extracted or split into project information within the scope of authority for downloading, and the corresponding project information can be output as text data in a standard format or a set format.

[0061] Specifically, after scanning the QR code provided by the designer, a group of characters starting with Control Character and Adderss are used to identify the subsequent data to make it a reality. By setting the minimum distinguishable interval between two adjacent discrete quantities of Resolution, the calculated value, observed value, and actual value of Error can be reduced to the lowest possible level, and other data will not be entered incorrectly, thereby achieving the purpose of extracting or stripping out the project information that needs to be downloaded, and maintaining confidentiality for project information that does not have permission.

[0062] In the method of this embodiment, after the establishment of the BIM server is completed, the search and / or stripping and / or downloading operations of the preset project data are performed through a fixed loop. After repeating the operation for 3 to 10 times, preferably 5 times, the operation is verified and the method stops after the operation is verified to be correct. This ensures the smooth operation of the BIM server and ensures that no data is missed or errors occur during the operation.

[0064] like Figure 2 As shown, this embodiment provides a BIM-based project information management system for executing the BIM-based project information management method as in the first embodiment, including a BIM server 10, a data transmission device 20 and multiple client terminals 30.

[0065] A BIM server 10 is provided with a user information storage module 101; a data transmission device 20 is communicatively connected to the BIM server 10, the user information storage module 101 is electrically connected to the data transmission device 20, and the data transmission device 20 is used to organize and classify the uploaded project information; the user terminal 30 registers the user information of the user who logs in to the BIM server 10 for the first time, and subsequently logs in to the BIM server 10 through the registered user information, and multiple user terminals 30 are communicatively connected to the input end of the data transmission device 20.

[0066] Specifically, the user terminal 30 includes a display 301, a data processor 302 and an input device. The input device is communicatively connected to the input end of the data processor 302, and the display 301 is communicatively connected to the output end of the data processor 302. The data processor 302 is provided with at least one data transmission port. The input device may include a keyboard 303 and a mouse 304. Biometric information login or QR code login may also be performed through a camera 305. The display 301 may be a liquid crystal display 301.

[0067] Specifically, the data processor 302 (Data Processor) can refer to various types of devices, among which the DPU (Data Processing Unit) is a new type of data processing unit, which integrates RDMA, network functions, storage functions, security functions, and virtualization functions. The DPU takes over data processing tasks such as network protocol processing, data encryption and decryption, and data compression that the CPU is not good at, while taking into account the needs of transmission and calculation. The data transmission device 20 includes a data transmission interface, a buffer, and an Ethernet module. The outer end of the data transmission interface is connected to the data transmission port signal, and the inner end is provided with a selection input switch. The two input ends of the selection input switch are respectively connected to the input end of the buffer and the Ethernet module signal, and the output end of the buffer is connected to the Ethernet module signal; the BIM server 10 is connected to the Ethernet module signal of the data transmission module, and the user end 30 is connected to the BIM server 10 signal through the data transmission module.

[0068] Furthermore, the user information storage module 101 includes an access authority determination module 1011, a user communication module 1012 and a BIM model storage module 1013. The access authority determination module 1011 is used to check the input user information and the extraction code information of the downloaded project data, and the access authority determination module 1011 is connected to the data transmission device 20 for communication; the user communication module 1012 is used for communication between users, and the user communication module 1012 is electrically connected to the user terminal 30; the BIM model storage module 1013 is used to store the integrated model file, and store the BIM model file updated and / or improved by the data transmission device 20, and establish a BIM model database, and the BIM model storage module 1013 is electrically connected to the user communication module 1012.

[0069] Specifically, after establishing a BIM server 10 for a project and connecting the data transmission device 20 and the user terminal 30, the BIM server 10 can be used through the user terminal 30. For example, a construction project, and the users of the project can be roughly divided into: owners, designers, construction, supervisors and suppliers, and the description is based on this classification.

[0070] After registering on the BIM server 10 using the mouse 304, keyboard 303 and display 301, the BIM server 10 can be used to upload data. The data transmission device 20 organizes and classifies the uploaded data, and then stores it in the storage hard disk of the BIM server 10 to complete the storage of project information. After integrating the data provided by users with different identities, a BIM model file of the building project can be generated to make full use of the model and effectively ensure the sharing of data terminals.

[0071] When it is necessary to download the data stored in the BIM server 10, an extraction code needs to be generated by the BIM server 10, and then the identity and extraction code are verified by the access authority determination module 1011. After the conditions are met, the user is allowed to download. In addition, the downloaded content is limited by the extraction code. For example, the owner can download the data uploaded by the owner. If the data of the designer user needs to be downloaded (other parties can obtain the required data in the same way), the designer can provide the extraction code for downloading to ensure the security of the data in the BIM server 10.

[0072] Furthermore, in order to facilitate communication between users, a user communication module 1012 is provided in the user information storage module 101 for users to communicate, so as to achieve the purpose of real-time communication and improve the convenience and practicality of use.

[0073] Specifically, the user communication module 1012 includes a file upload module, a file download module, a message module and a reply module. The file upload module and the file download module are respectively connected to the BIM model storage module 1013 by signals. The upload path of the file upload module is saved in the BIM model storage module 1013, and the download path of the file download module is downloaded from the BIM model storage module 1013. A network link is provided between the BIM model storage module 1013 and the message module, and a reply module link is provided on the message module to realize communication between users. For example: existing WeChat, QQ, enterprise WeChat or DingTalk, etc., or message and reply modules similar to mailboxes, to realize the convenience of communication.

[0074] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
