Example

[0030] like Figure 1 As shown, the present application provides a method for processing building construction data based on BIM, the method comprising the following steps:

[0031] Step S1, in response to the creation of a building construction project, receiving basic data of the building construction project.

[0032] As a specific embodiment of the present invention, the basic data of a construction project includes the geographical location, construction content, construction scope, construction time and construction materials of the construction project.

[0033] As a specific embodiment of the present invention, the data acquisition module acquires basic data of each construction project and sends the basic data of the construction project to the BIM construction information sharing platform.

[0039] Among them, the BIM construction model is used for construction. Based on the BIM construction model of the construction project to be referenced, a preliminary BIM construction model corresponding to the current construction project is established, which improves the efficiency of establishing the BIM construction model corresponding to the current construction project and realizes the rapid creation of the preliminary BIM construction model.

[0040] As a specific embodiment of the present invention, the BIM construction platform receives basic data of each construction project, and establishes a corresponding BIM construction model for each construction project based on the basic data of the construction project, so that the construction party can carry out construction according to the BIM construction model.

[0041] It needs to be explained that the BIM construction model displays the three-dimensional shape of the building of the simulated construction project, the constructed parts of the building, the unconstructed parts of the building and the construction progress (the completed construction content corresponding to each time communication node).

[0042] As a specific embodiment of the present invention, in the BIM building construction model, the constructed building parts are rendered with obvious colors, and the unconstructed building parts are not rendered in color and are in grayscale. Therefore, the constructed building parts and the unconstructed building parts can be clearly and intuitively seen according to the BIM building construction model, which is convenient for supervising and inspecting the construction progress.

[0043] Step S3, in response to the optimization operation request for the preliminary BIM building construction model, receiving the model optimization data of each authorized terminal, and integrating the received model optimization data to obtain the model optimization strategy.

[0044] As a specific embodiment of the present invention, the authorized terminal is a terminal device held by different types of professionals authorized by the BIM building construction platform. The types of professionals include architects, structural engineers, civil engineers, material engineers, quality and safety engineers, and cost engineers.

[0045] As a specific embodiment of the present invention, different types of professionals check the BIM construction model of the current construction project, regenerate component data that meets the requirements for components that do not meet the requirements, and replace the original components with the newly generated component data.

[0046] As a specific embodiment of the present invention, the components of the BIM building construction model include structural members, beams, columns, walls, roofs, curtain walls, doors, windows, panels, ramps, ramp sections, stairs, stair sections, handrails, etc.

[0047] As a specific embodiment of the present invention, based on the model optimization data of a certain authorized terminal, the authorized terminals associated with the current model optimization data are obtained, and the model optimization data of the authorized terminal are shared with the authorized terminals associated with the current model optimization data, so that after the current authorized terminal provides the model optimization data, the authorized terminals associated with it will formulate corresponding model optimization data based on the model optimization data provided by the current authorized terminal.

[0048] As a specific embodiment of the present invention, according to the component type involved in the model optimization data of a certain authorized terminal, the type of the authorized terminal with the corresponding associated impact is set, and the type of the authorized terminal with the associated impact corresponding to a type of component can be one or more. The types of authorized terminals include architects, structural engineers, civil engineers, material engineers, resource allocation engineers, quality and safety engineers, and cost engineers.

[0049] Among them, different types of authorized terminals optimize different model contents accordingly.

[0050] As a specific embodiment of the present invention, according to the model optimization data of a certain authorized terminal, a method for obtaining the authorized terminal associated with the current model optimization data includes:

[0051] Step S310, extracting an optimized feature sequence according to the model optimization data of the authorized terminal.

[0052] For example, the model optimization data sent by the architect is: the shape or spatial layout optimization and renovation design plan of a certain building, and the extracted optimization feature sequence includes: optimization component type, optimization parameters, and the optimization parameters include: optimization component complexity (different types of components correspond to different complexities), optimization area, and optimization cost budget.

[0053] Step S320: construct the corresponding associated optimization feature data according to the type of the authorized terminal.

[0054] As a specific embodiment of the present invention, the association optimization feature data includes the type of authorized terminal associated with the current authorized terminal and the type association coefficient between the current authorized terminal and the associated authorized terminal.

[0055] As a specific embodiment of the present invention, the type of the current authorized terminal is a structural engineer, and the corresponding associated authorized terminal types include: material engineer, resource allocation engineer, quality and safety engineer, and cost engineer. For example, the type of the authorized terminal is a structural engineer, and the type association coefficients of the authorized terminals corresponding to the material engineer, resource allocation engineer, quality and safety engineer, and cost engineer are 0.2, 0.3, 0.9, and 0.5, respectively, and the type association coefficients corresponding to other types of authorized terminals are 0.

[0056] As a specific embodiment of the present invention, the same type of authorized terminal includes a plurality of authorized terminals of different levels, and the authorized terminals of different levels correspond to different ranges of optimizable difficulty values. For example, the authorized terminal of the type of structural engineer includes authorized terminal one held by structural engineer one, authorized terminal two held by structural engineer two, authorized terminal three held by structural engineer three, etc. Different structural engineers have different levels, such as junior structural engineers, intermediate structural engineers, and senior structural engineers. Structural engineers of different levels have different ranges of optimizable difficulty values, and the ranges of optimizable difficulty values ​​for junior structural engineers, intermediate structural engineers, and senior structural engineers gradually increase.

[0057] Step S330, calculating the associated impact value of the model optimization data sent by the first authorized terminal and the second authorized terminal based on the optimized feature sequence extracted from the model optimization data sent by the first authorized terminal and the associated optimized feature data of the second authorized terminal.

[0058] The calculation formula of the model optimization data sent by the first authorized terminal and the associated impact value of the second authorized terminal is as follows:

[0059] ;

[0060] in, Indicates the type association factor. If the type of the first authorized terminal belongs to the type associated with the second authorized terminal, the type association factor ,otherwise ; Indicates the maximum value of the optimizable difficulty value range of the second authorized terminal; Indicates the total number of optimization parameters; Indicates The contribution weight of each optimization parameter to the overall optimization difficulty; Indicates The value of the optimization parameter; Indicates the type association coefficient of the first authorized terminal and the second authorized terminal; Represents a natural constant .

[0061] The present application improves the calculation accuracy of the model optimization data sent by the first authorization terminal and the associated influence value of the second authorization terminal, so as to accurately obtain the second authorization terminal with the largest associated influence value with the first authorization terminal, that is, obtain the second authorization terminal that best matches the first authorization terminal, and send the model optimization data sent by the first authorization terminal to the second authorization terminal, so as to analyze and design the model optimization data sent by the first authorization terminal according to the second authorization terminal.

[0062] Step S340: From the authorized terminal types associated with the current authorized terminal, select the second authorized terminal with the largest association impact value with the first authorized terminal from each type of authorized terminal as the authorized terminal associated with the current model optimization data. The authorized terminal associated with the current model optimization data is also the associated shared authorized terminal.

[0063] Specifically, among the types of authorized terminals associated with the current authorized terminal, from each type of authorized terminals, select the authorized terminal with the largest association influence value with the authorized terminal currently sending model optimization data as the authorized terminal associated with the authorized terminal currently sending model optimization data, and also as the associated shared authorized terminal of the authorized terminal currently sending model optimization data.

[0064] As a specific embodiment of the present invention, the model optimization data of the first authorized terminal is shared with the associated shared authorized terminals.

[0065] Specifically, the model optimization data of the first authorized terminal is shared with the associated shared authorized terminal, so that the associated shared authorized terminal can receive the model optimization data of the first authorized terminal, and then perform corresponding model optimization design or model optimization evaluation according to the model optimization data sent by the first authorized terminal, and judge whether the model optimization data of the first authorized terminal meets the preset quality, design, cost or safety requirements. Sharing the model optimization data of the first authorized terminal with the associated shared authorized terminal speeds up the speed at which the associated shared authorized terminal obtains the model optimization data of the first authorized terminal, speeds up the analysis speed or processing speed of the model optimization data of the first authorized terminal by the associated shared authorized terminal, and thus improves the reliability and efficiency of the optimization and modification of the BIM building construction model.

[0066] As a specific embodiment of the present invention, based on the model optimization data for adding stairs provided by the architect, since adding stairs will generate the need for material selection and cost assessment, the material engineer performs material selection and the cost engineer performs cost assessment. Therefore, the model optimization data for adding stairs is shared with the material engineer and the terminal device corresponding to the cost engineer, so that the material engineer can select materials and the cost engineer can perform cost assessment.

[0067] As a specific embodiment of the present invention, the method for integrating the received model optimization data to obtain the model optimization strategy includes: when the professionals from all parties reach a consensus on the model optimization data of the current BIM building construction model (i.e., it meets the requirements), aggregating all the model optimization data that have been unanimously approved by the professionals from all parties as the model optimization strategy.

[0068] Step S4: According to the model optimization strategy, the preliminary BIM building construction model is optimized and modified to obtain the BIM building construction model.

[0069] As a specific embodiment of the present invention, the BIM building construction model is optimized and modified according to the model optimization strategy of the model optimization data that has been unanimously approved by all professionals from all parties, thereby improving the reliability and efficiency of the optimization and modification of the BIM building construction model.

[0070] As a specific embodiment of the present invention, the model optimization strategy includes a solution for optimizing and modifying a certain component, and the optimization and modification includes adding, deleting or replacing a certain component.

[0071] Step S5: for each construction project, receiving the construction request processing task sent by the request terminal, and collecting the request terminal risk characteristic data and task risk characteristic data corresponding to the construction request processing task.

[0072] As a specific embodiment of the present invention, step S5 includes the following steps:

[0073] Step S510, in response to the request terminal uploading a construction request processing task containing construction abnormality data, the request terminal is authenticated. If the identity authentication is passed, the construction request processing task containing the construction abnormality data sent by the request terminal is received; otherwise, the construction request processing task containing the construction abnormality data sent by the request terminal is prohibited from being received.

[0074] Step S520, after receiving the construction request processing task, collect the request terminal risk characteristic data and task risk characteristic data corresponding to the construction request processing task.

[0075] Among them, the risk characteristic data of the requesting terminal include: the type management level value of the requesting terminal (the type management level values ​​include: 1, 2, 3, representing general terminal equipment, intermediate management terminal equipment, advanced management terminal equipment, etc.), the trust index of the requesting terminal recorded by the system (each time the system responds to a construction request processing task of the requesting terminal, the trust index of the requesting terminal increases by 1), the IP address trust value of the requesting terminal (if the IP address of the requesting terminal is within the authorized range, the IP address trust value = 1, otherwise, the IP address trust value = 0), etc.

[0076] Among them, the task risk characteristic data include: the type of task, risk data and the amount of construction funds agreed in the contract for the construction project corresponding to the task.

[0077] Among them, the types of construction request processing tasks include: record type, inspection type, control type and financial type, etc. Among them, different types of construction request processing tasks correspond to different risk levels. According to the risk size corresponding to different types of construction request processing tasks, task type risk factors are set for different types of construction request processing tasks. The greater the risk in the process of processing construction request processing tasks, the greater the corresponding task type risk factor.

[0078] It should be explained that risk data is data with potential safety hazards identified from the data corresponding to the construction request processing task. Data with potential safety hazards include, for example, malicious code, malicious keywords, malicious address links, etc.

[0079] As a specific embodiment of the present invention, a record-type construction request processing task is, for example, recording construction-related data (including construction progress, construction material consumption, construction fund expenditure, construction problem data, etc.).

[0080] As a specific embodiment of the present invention, inspection-type construction request processing tasks include: requesting a quality inspection of the construction content, requesting to check whether the current construction cost is within a reasonable range, and requesting to check whether the current construction progress is up to standard.

[0081] As a specific embodiment of the present invention, the control type construction request processing task is, for example: requesting to increase the distribution of construction materials, requesting to increase construction personnel, requesting to control other departments to assist in the current construction, etc.

[0082] As a specific embodiment of the present invention, a financial type construction request processing task is, for example, requesting approval for the release of construction project funds.

[0083] Step S6, calculating a warning reference value of the construction request processing task according to the request terminal attribute characteristic data and the task risk characteristic data corresponding to the construction request processing task.

[0084] Specifically, the calculation formula for the alert reference value of the construction request processing task is:

[0085] ;

[0086] in, Indicates the alert reference value of the construction request processing task; Indicates the weight of the requested terminal attribute feature data; Indicates the total number of types of requested terminal attribute feature data; Indicates A weight factor for requesting terminal attribute feature data; represents a natural constant; Indicates A value of a request terminal attribute characteristic data; Represents the weight of the task risk feature data; ; Represents the risk impact weight of the task type risk factor; Indicates the task type risk factor corresponding to the type of the construction request processing task; Indicates the risk impact weight of data with potential safety risks; Indicates the total number of types of data with potential safety hazards identified from the data corresponding to the construction request processing task; Indicates identifying the first The number of data with security risks; Indicates identifying the first The dangerous value of data with potential safety risks; The risk impact weight of the amount of engineering payment agreed in the contract for the construction project corresponding to the task; Indicates the amount of engineering payment agreed in the contract for the construction project corresponding to the task. .

[0087] This application calculates the alert reference value of the construction request processing task based on the request terminal attribute feature data and task risk feature data corresponding to the construction request processing task, and improves the calculation accuracy of the alert reference value of the construction request processing task. According to the alert reference value of the construction request processing task, the task processing terminal with the corresponding security level is matched to process the construction request processing task, so that the construction request processing task with a larger alert reference value can be matched with a task processing terminal with a higher security level to process the task, thereby improving the security and reliability of task processing, avoiding security risks such as data leakage or tampering caused by using task processing terminals with mismatched security levels to process tasks, and improving the security of the data processing system.

[0091] Step S720, analyzing the abnormal construction data according to the task processing terminal of the selected safety level to obtain abnormal problems.

[0092] Step S730, an alarm is issued for the abnormal problem, and the abnormal problem is displayed on the corresponding BIM building construction model.

[0093] As a specific embodiment of the present invention, task processing terminals of different security levels are preset with corresponding alert reference value ranges for processable tasks. Among them, task processing terminals of different security levels have different alert reference value ranges for processable tasks, and task processing terminals with higher security levels have larger alert reference value ranges for processable tasks. According to the alert reference value of the current construction request processing task and the alert reference value ranges of the processable tasks corresponding to task processing terminals of different security levels that are preset, a task processing terminal of a security level corresponding to the alert reference value range within which the alert reference value of the current construction request processing task falls is selected, so that the construction request processing task is processed according to the task processing terminal of the selected security level.

[0094] Step S8, in response to the construction data acquisition request sent by the user end, collect the load characteristic data, performance characteristic data and security characteristic data of the communication nodes on the communication link, and the request characteristic data of the user end.

[0095] Specifically, in response to a construction data acquisition request sent by a user terminal, the load characteristic data, performance characteristic data and safety characteristic data of the communication nodes on the communication link, as well as the load characteristic data, performance characteristic data and safety characteristic data of the communication nodes are collected.
