Description

Technical Field

[0001] The present invention relates to the technical field of construction management, and in particular to a construction project visualization management method, platform and storage medium based on BIM simulation. Background Art

[0002] Construction project management refers to the management of the entire process of planning, organizing, arranging, directing, supervising, controlling and coordinating construction projects using systematic viewpoints and theories as well as modern scientific and technological means during the construction process. Its core lies in effectively coordinating resources from all parties to ensure the smooth progress of the project and thus achieve the project's goals. Visual management is a management method that uses visual perception information to organize on-site production activities, aiming to improve labor productivity through intuitive images and colors.

[0003] Existing methods for visual management of construction projects usually use BIM models, topography, and electronic maps to build an electronic sand table of the construction site, and operate the electronic sand table to obtain the construction progress of each construction project for management. Although this improved method can realize the visualization of the construction process of the engineering parts of the construction project, it cannot effectively analyze the construction status of the project workers of the construction project in the construction site. Therefore, when the construction behavior of the project workers is abnormal, such as the unreasonable movement trajectory of the project workers or cross-regional construction, the abnormal behavior cannot be checked based on the visual construction model, which leads to safety hazards in the construction project and affects the construction efficiency. For example, in the patent application with publication number CN112149212A, a visual construction management platform for engineering projects is disclosed. This solution is to use sand to The disk image unit and the roaming unit can preset roaming paths to dynamically display the electronic sand table image of the engineering project, thereby visually managing the construction project. Other methods for visual management of construction projects usually merge multiple subsystems used for construction projects and visualize them through BIM. This improvement method can increase the diversity of management methods, but the management of project workers can only be achieved through monitoring and positioning, and it is still impossible to effectively analyze the construction status of project workers in construction projects within the construction site. Therefore, when the construction behavior of project workers is abnormal, such as unreasonable movement trajectories of project workers or cross-regional construction, it is impossible to check the abnormal behavior based on the visual construction model, which leads to safety hazards in the construction project and affects construction efficiency. In view of this, it is necessary to improve the existing visual management methods for construction projects. Summary of the Invention

By proposing a construction project visualization management method, platform and storage medium based on BIM simulation, the present invention is used to solve the problem in the existing construction project visualization management method that it is impossible to effectively analyze the construction status of project workers in the construction project within the construction site.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] Example 1, please refer to Figure 1 As shown, this application provides a construction project visualization management platform based on BIM simulation, including a worker stage analysis module, a construction conflict analysis module, and an optimization sharing module;

[0050] The worker phase analysis module is used to build a 3D model using BIM based on design drawings, engineering parameters, and construction plans, and record it as a construction visualization model. It also performs scenario simulation in the construction visualization model based on the construction sequence, and obtains the process phase points and cross-domain phase points of project workers in the construction project based on the results of the scenario simulation.

[0051] The worker phase analysis module includes a construction process analysis unit, which is equipped with a construction process analysis strategy. The construction process analysis strategy includes: building a three-dimensional model in BIM based on design drawings, engineering parameters and construction plans, and recording it as a construction visualization model, wherein the construction plan includes construction projects and the construction site corresponding to each construction project; obtaining all construction projects based on the construction sequence in the construction plan, and recording all construction projects in order from the earliest to the latest based on the construction time as visualization projects KX1 to visualization projects KX n ;

[0052] During the specific implementation process, all construction projects can be marked as visualization projects KX according to the order of all construction projects carried out on the construction site in the actual construction plan. For example, if the construction plan is a civil engineering project, and the construction projects are foundation engineering, earthwork engineering, masonry engineering, concrete engineering, steel engineering, wood structure engineering, wall engineering, floor engineering, roof engineering, staircase engineering and decoration engineering, then the above projects can be recorded in sequence as multiple visualization projects for subsequent analysis.

[0053] For any visualization project KX c , c is any one from 1 to n, the visualization project KX c The workers working in the corresponding construction site are recorded as project workers; a plane rectangular coordinate system is established and recorded as the site personnel analysis coordinate system, where the units of the X-axis and Y-axis of the site personnel analysis coordinate system are both m; the visualization project KX c The top view of the corresponding construction site is placed in the first quadrant of the site personnel analysis coordinate system and recorded as the site area; the points corresponding to the maximum and minimum values ​​of the vertical coordinate in the site area are recorded as the upper reference point and the lower reference point respectively, and the points corresponding to the maximum and minimum values ​​of the horizontal coordinate in the site area are recorded as the right reference point and the left reference point respectively;

[0054] In the specific implementation process, for example, during a data processing, the site personnel analysis coordinate system is obtained as follows Figure 3 As shown in the figure, the area where QY is located is the site area, TO, LO, RE and LE are the upper reference point, lower reference point, right reference point and left reference point in the site area respectively; point RY is the location of the project worker, and the length from LL1 to LL4 is the distance between the upper reference point, lower reference point, right reference point and left reference point and the worker point. By analysis, we can get [TO, LO, RE, LE] max is the distance between point LO and the worker point, that is, the distance between the lower reference point and the worker point;

[0055] For any project worker, based on the visual project KX cGet the construction area of ​​the project workers; when the construction area is completely within the site area, simulate the movement trajectory of the project workers in the site area based on the scene simulation, and record the point where the project workers are located in the scene simulation as the worker point; [TO, LO, RE, LE] max Recorded as the distance feature value of the worker point, where [TO, LO, RE, LE] max is the value corresponding to the maximum value among TO, LO, RE and LE, TO is the distance between the upper reference point and the worker point, LO is the distance between the lower reference point and the worker point, RE is the distance between the right reference point and the worker point, and LE is the distance between the left reference point and the worker point;

[0056] In the specific implementation process, for example, during a data processing, the TO, LO, RE, and LE obtained are 10, 20, 15, and 9 respectively. Then, through analysis, it can be found that when the construction area is completely within the site area, the distance characteristic value can be set to 20; when the construction area is completely outside the site area, the distance characteristic value can be set to 9. By obtaining the distance characteristic value, the position characteristics of the project workers during construction can be obtained, which is conducive to controlling the position of the project workers and thus managing the project workers.

[0057] Establish a plane rectangular coordinate system, recorded as the four-way distance analysis coordinate system, where the unit of the X axis of the four-way distance analysis coordinate system is time and the unit of the Y axis is meter; based on the motion trajectory of the project worker in the simulation, [TO, LO, RE, LE] max The corresponding curve is drawn in the four-way distance analysis coordinate system, recorded as the process analysis curve, and the process stage points in the process analysis curve are marked. The process stage points are the points where the maximum values ​​of TO, LO, RE and LE change when the process analysis curve is drawn;

[0058] When part of the construction area is within the site area, the area where the construction area overlaps with the site area is recorded as the inner application area, and the area where the construction area does not overlap with the site area is recorded as the outer application area; based on the scene simulation, the movement trajectory of the project workers in the site area is simulated, and a four-way distance analysis coordinate system is established to obtain the corresponding process analysis curve; the process stage points, outer application line segments and inner application line segments in the process analysis curve are marked, wherein the outer application line segment is the line segment in the process analysis curve corresponding to the project workers in the outer application area, and the inner application line segment is the line segment in the process analysis curve corresponding to the project workers in the inner application area;

[0059] In the specific implementation process, for example, during a data processing, the construction area and site area are obtained as follows: Figure 4As shown in the figure, the solid line area where QY is located is the site area, and the dotted line area where SG is located is the construction area. By drawing the process analysis curve, it is obtained that points DD1, DD2, and DD3 are all process stage points. Since points DD2 and DD3 are in the external application area, points DD2 and DD3 are recorded as cross-domain stage points to help distinguish the process stage points within the site area and outside the site area.

[0060] When there is a process stage point in the external application segment, the process stage point in the external application segment is recorded as the cross-domain stage point, and the cross-domain distance is recorded as 0; when there is no process stage point in the external application segment, the point in the internal application segment closest to the external application segment is recorded as the cross-domain stage point, and the cross-domain distance is recorded as the shortest distance between the cross-domain stage point and the external application segment;

[0061] When the construction area is completely outside the site area, the movement trajectory of the project workers outside the site area is simulated based on the scenario simulation, and [TO, LO, RE, LE] is used to simulate the movement trajectory of the project workers outside the site area. min Record the distance characteristic value of the worker point as the distance characteristic value, and establish a four-way distance analysis coordinate system to obtain the corresponding process analysis curve based on the distance characteristic value; mark the process stage points in the process analysis curve, where the process stage points are the points where the minimum values ​​of TO, LO, RE and LE change when the process analysis curve is drawn;

[0062] Obtain the process phase points corresponding to all project workers in all visualized projects KX and the cross-domain phase points of project workers whose construction areas are partially within the site area.

[0063] The construction conflict analysis module is used to integrate the construction visualization model with the construction schedule software and record the resulting model as the construction schedule model. It also obtains the points to be optimized for project workers based on process stage points, cross-domain stage points, and the construction schedule model.

[0064] The construction contradiction analysis module includes a unit for obtaining points to be optimized, and the unit is configured with a strategy for obtaining points to be optimized. The strategy for obtaining points to be optimized includes: integrating a construction visualization model with a construction schedule software, and recording the obtained model as a construction schedule model;

[0065] Use the construction progress model to simulate all construction projects in sequence; for any visualization project KX during the simulation c Any project worker in: Based on the method for obtaining the process analysis curve of the project worker, obtain the process analysis curve again when simulating the construction progress model, and record the process analysis curve obtained at this time as the contradiction comparison curve;

[0066] Put the process analysis curve and the contradiction comparison curve into the same four-way distance analysis coordinate system, and use the coincidence comparison algorithm to obtain the contradiction threshold corresponding to the project workers. The coincidence comparison algorithm is: Among them, F is the contradiction threshold, f jc is the number of process stage points in the area of ​​the process analysis curve that does not overlap with the contradiction comparison curve, f sum is the number of process stage points in the process analysis curve, f ky It is the number of cross-domain stage points in the process analysis curve that does not overlap with the contradiction comparison curve;

[0067] In the specific implementation process, for example, during a data processing, f is obtained jc is 1, f sum is 4, and f ky If f is 1, then the contradiction threshold is -0.75. The calculation result shows that since the contradiction threshold is less than 0, the number of cross-domain stage points in the area that does not overlap with the contradiction comparison curve in the process analysis curve is greater than 0, indicating that the project workers have cross-region construction behavior. Therefore, the cross-domain stage points of the project workers should be recorded as the points to be optimized for project workers, so as to manage them. If the threshold is less than 0 and greater than -1, it means that f jc Divide by f sum Less than 1, that is, the number of process stage points in the area of ​​the process analysis curve that does not overlap with the contradiction comparison curve is greater than 0. Therefore, the process stage points in the area of ​​the process analysis curve that does not overlap with the contradiction comparison curve can be recorded as points to be optimized for project workers, thereby managing them;

[0068] When the contradiction threshold is 0 and f ky When it is 0, no optimization point is set for the project worker;

[0069] When the contradiction threshold is 0 and f ky When it is not 0, all process stage points and cross-domain stage points of the project worker are recorded as the project worker's points to be optimized;

[0070] When the contradiction threshold is less than 0 and greater than -1, the process stage points in the process analysis curve that do not overlap with the contradiction comparison curve and the cross-domain stage points of the project workers are recorded as the project workers' points to be optimized;

[0071] When the contradiction threshold is equal to -1, the cross-domain stage point of the project worker is recorded as the point to be optimized of the project worker;

[0072] When the contradiction threshold is less than -1, the process stage points in the process analysis curve that do not overlap with the contradiction comparison curve and the cross-domain stage points of the project workers are recorded as the project workers' points to be optimized;

[0073] When the contradiction threshold is less than 1 and greater than 0, the process stage points in the area of ​​the process analysis curve that do not overlap with the contradiction comparison curve are recorded as the project worker's points to be optimized;

[0074] When the contradiction threshold is equal to 1, all process stage points of the project worker are recorded as the project worker's points to be optimized;

[0075] Get the points to be optimized corresponding to all project workers.

[0076] The optimization sharing module is used to build a collaborative platform based on cloud computing and share the construction visualization model, construction progress model, and points to be optimized in real time. The optimization sharing module includes an optimization sharing unit, which is configured with an optimization sharing strategy. The optimization sharing strategy includes:

[0077] A collaboration platform is built based on cloud computing, and the construction visualization model, construction progress model and the points to be optimized of all project workers are stored in the collaboration platform; when the construction project starts and the real-time progress of the construction project coincides with the point to be optimized of any project worker, the project workers corresponding to the point to be optimized that coincides with the real-time progress are monitored in real time; in the specific implementation process, for example, during a data processing, it is found that the point to be optimized of a project worker in an earthwork project is 10 minutes and 40 seconds after the start of the earthwork project, then the project worker can be monitored in real time 10 minutes and 40 seconds after the start of the earthwork project to prevent construction safety hazards.
