Description

Technical Field

[0001] The present invention relates to the field of intelligent management technology, and more specifically to an intelligent management system for a building construction process based on BIM technology. Background Art

[0002] BIM technology is a digital tool used in engineering design, construction, and management. By integrating the digital and information models of buildings, it is shared and transmitted throughout the entire life cycle of project planning, operation, and maintenance. It enables engineering and technical personnel to correctly understand and efficiently respond to various building information, providing a basis for collaborative work for design teams and all construction entities including construction and operating units, and plays an important role in improving production efficiency, saving costs, and shortening construction periods.

[0003] However, the existing management of construction is often only achieved through simple BIM technology. During the construction process, there will be deviations in construction accuracy, so it is necessary to monitor the construction process in real time. Construction points with large deviations need to be reconstructed to ensure the safety of the building, which requires the reallocation of resources in the construction process. The existing management of the construction process does not monitor and warn the construction status of the building in real time, and does not reallocate resources based on the real-time construction status. Summary of the invention

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The intelligent management system for the construction process based on BIM technology involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0039] The present invention provides an intelligent management system for building construction process based on BIM technology, including a data acquisition module, a BIM model management module, a building construction real-time monitoring module, a construction scheduling plan generation module, an early warning module, a deviation analysis module, a construction scheduling plan update module and a human-computer interaction module;

[0040] The data acquisition module is used to collect drawing data, construction data and real-time data; the drawing data is the CAD drawing of the building; the construction data includes but is not limited to the construction period, construction process, construction components and construction equipment; the real-time data is the real-time data during the construction of the building, that is, the real-time construction data and the real-time building image, and the real-time building image can be obtained by 3D scanning technology;

[0041] The BIM model management module constructs a standard building model based on the image data and constructs a real-time building model through the real-time building image;

[0042] The real-time construction monitoring module is used to compare the real-time building model with the standard building model. If a deviation occurs, an early warning instruction is sent to the early warning module, and the data is transmitted to the deviation analysis module at the same time;

[0043] The construction scheduling scheme generating module generates an initial construction scheduling scheme based on the construction data and executes it;

[0044] The warning module is used to receive warning instructions to issue deviation warnings, indicating that deviations occur during the construction process and need to be corrected. At this time, the staff needs to conduct on-site inspections to prevent construction deviations from occurring during the construction process, leading to potential safety hazards in the building, reduce safety risks, and ensure construction quality;

[0045] The deviation analysis module is used to obtain the amount of resources, construction time and construction process required to correct the deviation;

[0046] The construction scheduling scheme updating module generates a new construction scheduling scheme based on the data of the deviation analysis module and transmits it to the construction scheduling scheme generating module for updating and execution;

[0047] The human-computer interaction module is used to perform human-computer interaction display on the data.

[0048] In this embodiment, it should be specifically explained that after the BIM model management module constructs the standard building model, n key building points are selected and marked as (X1, Y1, Z1), (X2, Y2, Z2), (X3, Y3, Z3), ..., (X n , Y n , Z n ) The key building points are the outline points and bearing points of the building;

[0049] The real-time building model selects the same key building points, which are marked as (x1, y1, z1), (x2, y2, z2), (x3, y3, z3), ..., (x n ,y n 、z n ) The real-time building model only selects the corresponding key building points that have been completed, and those that have not been constructed are not marked for the time being. The key building points are all one-to-one corresponding.

[0050] In this embodiment, it should be specifically explained that the specific manner in which the real-time construction monitoring module compares the real-time building model with the standard building model is:

[0051] Step S01: Calculate the distance deviation: by formula Calculate the distance deviation of the i-th key building point between the standard building and the real-time building, where d i is the distance deviation of the i-th key building point; X i is the x-axis coordinate of the ith key building point in the standard building model, Y i is the y-axis coordinate of the i-th key building point in the standard building model, Z iis the z-axis coordinate of the ith key building point in the standard building model; i is the x-axis coordinate of the ith key building point in the real-time building model, and y i is the y-axis coordinate of the i-th key building point in the real-time building model, z i is the z-axis coordinate of the ith key building point in the real-time building model;

[0052] Step S02: If d i Satisfy i ≥d′, then execute step S03, otherwise directly execute step S05; wherein d′ is the distance error value, and d′<0.5 is the maximum error value allowed in the construction process. Since the measurement error value may occur in the construction measurement process, it does not affect the overall construction of the building;

[0053] Step S03: Calculate the direction deviation: by formula Calculate the direction deviation of the i-th key building point between the standard building and the real-time building, where D i is the direction deviation of the i-th key building point, indicating the direction from the i-th key building point of the standard building to the i-th key building point of the real-time building;

[0054] Step S04: sending a warning instruction to the warning module; at the same time, transmitting the value of the distance deviation and the value of the direction deviation to the deviation analysis module;

[0055] Step S05: Transmitting data to the human-computer interaction module.

[0056] In this embodiment, it should be specifically explained that the construction scheduling scheme generation module establishes a scheduling model to generate an initial construction scheduling scheme. The scheduling model takes the shortest construction period as the target condition. The target condition of the scheduling model is expressed as minT max ;

[0060]

[0061] Among them, t jk is the start time of the kth construction process of the jth component to be constructed; a jk T is the time required for the construction of the kth construction process of the jth component to be constructed; maxis the maximum construction period; J is the total number of components to be constructed, j = 1, 2, 3...J; s j is the total number of construction procedures for the jth component to be constructed; t j，k+1 is the start time of the k+1th construction process of the jth component to be constructed; r jm is the number of m-th resource occupied by the k-th construction process of the j-th component to be constructed; R m is the total number of the mth resource; S is the set of construction procedures, S = {s1, s2, s3, …, s j ,…s J}, where s J is the total number of construction processes for the Jth component to be constructed;

[0062] Formula (1) means that the completion time of the last process of all components is less than or equal to the completion time T max ; Formula (2) indicates that the construction procedures of the same component must be completed in sequence, and the next procedure can only be started after the previous procedure is completed; Formula (3) indicates the resource constraint of the construction activity, that is, the total resource demand of all activities in the construction process does not exceed its upper limit R m ; Formula (4) indicates that the start time of the construction process is non-negative.

[0063] In this embodiment, it should be specifically explained that the deviation analysis module obtains the construction time P1 and the amount of resources P2 required to correct the deviation based on the values ​​of the distance deviation and the direction deviation by conducting on-site surveys of key building points where the deviation occurs.

[0064] In this embodiment, it should be specifically explained that the construction scheduling scheme updating module updates the scheduling model to generate a new construction scheduling scheme, and the updated scheduling model still takes the shortest construction period as the target condition;

[0065]

[0066] P2+∑r jm ≤R m ; (6)

[0067] Among them, t jk is the start time of the kth construction process of the jth component to be constructed; a jk T is the time required for the construction of the kth construction process of the jth component to be constructed; max is the maximum construction period; J is the total number of components to be constructed, j = 1, 2, 3...J; s j is the total number of construction procedures for the jth component to be constructed; r jm is the number of m-th resource occupied by the k-th construction process of the j-th component to be constructed; R mis the total quantity of the mth resource; P1 is the construction time required to correct the deviation; P2 is the amount of resources required to correct the deviation;

[0068] Formula (5) is the updated formula (1), indicating that the completion time of the last process of all components plus the construction time required to correct the deviation is less than or equal to the completion time; Formula (6) is the updated formula (3), indicating that the total resource demand of all activities in the construction plus the amount of resources required to correct the deviation does not exceed its upper limit R m .

[0069] In this embodiment, it should be specifically explained that if the real-time construction monitoring module does not meet the conditions for sending an early warning instruction to the early warning module after comparing the real-time building model with the standard building model, the initial construction scheduling plan generated by the construction scheduling plan generation module will continue to be executed; when the construction scheduling plan update module updates the scheduling model to generate a new construction scheduling plan, except for formula (1) and formula (3), the other formulas are not updated, so the formulas in the initial construction scheduling plan are still used.

[0070] In this embodiment, it should be specifically explained that the method for using an intelligent management system for a construction process based on BIM technology is specifically as follows:

[0071] Collect CAD drawing data, construction data and real-time data during building construction;

[0072] A standard building model, i.e. the prototype of the building to be completed, is constructed through the collected CAD drawing data. At the same time, real-time data of the building during the construction process is obtained through 3D scanning technology, and a real-time building model is constructed through BIM technology, which is updated synchronously with the building during the actual construction process.

[0073] Generate an initial construction scheduling plan based on the collected construction data and execute the plan;

[0074] Compare the key building points of the building in the real-time building model with those in the standard building model, and analyze whether there are deviations in the building outline points or key bearing points during the actual construction process. If there are deviations, it will cause safety hazards in the subsequent construction process of the building, and even cause the final acceptance stage to fail to meet the standards. If there are deviations, send an early warning instruction to prompt the staff to conduct on-site inspections in a timely manner;

[0075] When the comparison results of key building points of the building in the real-time building model and the standard building model deviate, secondary construction is required to correct the deviation and ensure the quality of the building. At this time, the initial construction scheduling plan needs to be updated, and a new construction scheduling plan needs to be generated and executed;

[0076] Obtain the construction time and resources required to correct the deviation, and generate a new construction scheduling plan based on the initial construction scheduling plan to meet the construction scheduling requirements for secondary construction during the construction process;

[0077] Therefore, the real-time monitoring of the building construction process can be combined to carry out intelligent management of the building construction process, and the construction resources can be scheduled and reallocated based on the real-time construction situation.

[0078] In this embodiment, it should be specifically explained that the difference between this embodiment and the prior art is that this embodiment has a real-time monitoring module for building construction, an early warning module and a deviation analysis module, which is conducive to comparing the real-time building model with the standard building model. If a deviation occurs, an early warning instruction is sent to the early warning module for deviation warning, prompting the staff that a deviation occurs in the building construction process and a deviation correction is required to prevent the building from failing to meet the acceptance standards and prevent potential safety hazards. Based on the values ​​of the distance deviation and the direction deviation, the amount of resources, construction time and construction process required to correct the deviation are obtained, which lays the foundation for the subsequent generation of a new construction scheduling plan. At the same time, the building construction process is monitored in real time, and construction points with large deviations are re-constructed to ensure the safety of the building; the embodiment has a construction scheduling plan generation module and a construction scheduling plan update module, which is conducive to generating and executing an initial construction scheduling plan based on construction data. In the process of monitoring the building construction process, a new construction scheduling plan is generated for the situation where a deviation occurs and re-construction is required. Resources are redistributed based on the real-time construction situation, and flexible resource scheduling optimization is performed for the secondary construction situation that occurs during the construction process, so as to improve the intelligent management of the building construction process and thus improve the construction efficiency.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
