Description

Technical Field

[0001] The present application relates to the technical field of project management, and in particular to a full-process tracking method and system for construction project management. Background Art

[0002] In construction projects, the project leader usually controls the project construction progress. In order to avoid delays in the construction progress, a supervision team needs to be set up to supervise the project construction progress. The members of the supervision team need to collect a large amount of project data in real time, and analyze and process the project data in combination with the project plan to analyze the status of the project construction progress, thereby supervising the project leader.

[0003] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: a large amount of manpower is required in the process of supervising the progress of project construction. Summary of the invention

[0004] In order to improve the defect that a large amount of manpower is required in the process of supervising the progress of project construction, the present application provides a full-process tracking method and system for construction project management.

[0005] In a first aspect, the present application provides a full-process tracking method for construction project management, the method comprising the following steps:

[0006] Build a construction simulation model based on the project plan of the construction project;

[0007] Collecting construction site images during the construction of the building project;

[0008] Acquire the number of construction personnel and the number of construction equipment based on the construction site image;

[0009] Analyze the actual construction progress nodes of the construction process in combination with the number of construction personnel, the number of construction equipment and the project plan;

[0010] Extracting a corresponding planning simulation model from the construction simulation model according to the actual construction progress node;

[0011] Combine the planned simulation model and the construction site image for comparison and analysis to obtain the progress status of the construction process;

[0012] The project performance points of the project leader in the project plan are adjusted based on the progress status.

[0013] By adopting the above technical solution, a construction simulation model is first constructed according to the project plan, and then the construction site images during the construction process are collected. Based on the image recognition technology, the number of construction personnel and the number of construction equipment are obtained through the construction site images, so that the actual construction progress nodes of the construction process can be analyzed in combination with the project plan, and then the corresponding plan simulation model is extracted from the construction simulation model through the actual construction progress nodes. The plan simulation model is a construction simulation model when the actual construction progress node corresponds to the planned construction node in the project plan. Therefore, the actual construction site images and the plan simulation model at the same time node can be compared and analyzed to analyze the progress status of the construction process. Finally, the project performance points of the project leader are adjusted according to the progress status. The project performance points will affect the overall assessment of the project leader. The project leader with a low project performance point will be disqualified from the project leader. Therefore, the project performance points can be used to supervise the project leader and enable the project leader to control the project construction progress in a timely manner.

[0014] Optionally, analyzing the actual construction progress nodes of the construction process in combination with the number of construction personnel, the number of construction equipment and the project plan comprises the following steps:

[0015] Identifying planned construction milestones in the project plan;

[0016] Count the number of planned personnel and the number of planned equipment at all planned construction nodes in the project plan respectively;

[0017] Determining whether the planned equipment quantity is the same as the construction equipment quantity;

[0018] If the planned equipment quantity is not the same as the construction equipment quantity, it is determined that the corresponding planned construction node is not an actual construction progress node;

[0019] If the planned equipment quantity is the same as the construction equipment quantity, then the difference between the construction personnel quantity and the planned personnel quantity is calculated;

[0020] Determine whether the quantity difference is less than a preset difference threshold;

[0021] If the quantity difference is less than the difference threshold, determining the corresponding planned construction node as the actual construction progress node;

[0022] If the quantity difference is greater than or equal to the difference threshold, it is determined that the corresponding planned construction node is not the actual construction progress node.

[0023] By adopting the above technical solution, multiple planned construction nodes will be divided into the entire project plan according to the progress of the project. The construction content, construction personnel arrangement and construction equipment arrangement of each planned construction node are different. Therefore, the number of planned personnel and the number of planned equipment at each planned construction node in the project plan can be counted first. The construction equipment of construction projects is usually large-scale equipment, and the use of large-scale equipment will basically not be different from the plan. Therefore, the number of construction equipment and the number of planned equipment are compared first. If the number of construction equipment and the number of planned equipment are different, it directly indicates that the corresponding planned construction node is not the actual construction progress node; and construction personnel may have temporary scheduling or leave, etc., so the difference between the number of construction personnel and the planned number of personnel can be calculated, and then the difference in number can be compared with the preset difference threshold to determine whether the corresponding planned construction node is the actual construction progress node.

[0024] Optionally, the combining and comparing the planned simulation model and the construction site image to obtain the progress status of the construction process includes the following steps:

[0025] generating a 3D image of the construction site according to the construction site image;

[0026] Marking overlapping reference points in the planned simulation model and the on-site 3D image respectively based on preset reference point coordinates;

[0027] Overlapping the planned simulation model and the on-site 3D image based on the overlap reference point;

[0028] Calculating the model overlap rate between the planned simulation model and the on-site 3D image;

[0029] Determining whether the model overlap rate is greater than a preset overlap rate threshold;

[0030] If the model overlap rate is less than or equal to the overlap rate threshold, it is analyzed that the construction process is in a normal progress state;

[0031] If the model overlap rate is greater than the overlap rate threshold, the progress status of the construction process is analyzed based on the overlapped portion of the planned simulation model and the on-site 3D image.

[0032] By adopting the above technical solution, a 3D image of the site is generated based on the image of the construction site, and then the 3D image of the site at the actual construction node is overlapped and compared with the planned simulation model at the corresponding planned node. To ensure the perfect overlap of the 3D image and the simulation model, it is necessary to first mark the overlap reference point according to the preset reference point coordinates, and then overlap the 3D image and the simulation model with the overlap reference point. After the overlap, the model overlap rate of the planned simulation model and the site 3D image can be calculated, and the model overlap rate can be compared with the preset overlap rate threshold. If the model overlap rate is less than or equal to the overlap rate threshold, the construction process is in a normal progress state; if the model overlap rate is greater than the overlap rate threshold, it is necessary to further analyze the progress state of the construction process based on the overlapped part.

[0033] Optionally, analyzing the progress status of the construction process based on the overlapped portion of the planned simulation model and the on-site 3D image comprises the following steps:

[0034] Deleting the overlapping parts of the planned simulation model and the on-site 3D image;

[0035] Calculating a model residual surface area of ​​a remaining portion of the planned simulation model and an image surface area of ​​a remaining portion of the on-site 3D image;

[0036] Determining whether the residual surface area of ​​the model is greater than the surface area of ​​the image;

[0037] If the residual surface area of ​​the model is larger than the surface area of ​​the image, it is analyzed that the construction process is in a state of falling behind schedule;

[0038] If the residual surface area of ​​the model is smaller than the surface area of ​​the image, it is analyzed that the construction process is in an advanced progress state.

[0039] By adopting the above technical solution, most of the planned simulation model and the on-site 3D image are buildings that need to be built for the construction project. Therefore, the overlapping parts of the planned simulation model and the on-site 3D image can be deleted, and then the surface areas of the remaining parts are compared. If the residual surface area of ​​the model of the planned simulation model is larger than the image surface area of ​​the on-site 3D image, it means that the on-site construction situation of the building has not reached the planned construction situation, so it can be analyzed that the construction process is in a backward progress state; if the residual surface area of ​​the model of the planned simulation model is smaller than the image surface area of ​​the on-site 3D image, it means that the on-site construction situation of the building has exceeded the planned construction situation, so it can be analyzed that the construction process is in an advanced progress state.

[0100] 208, determining that the corresponding planned construction node is not an actual construction progress node.

[0101] The implementation principle of this embodiment is:

[0102] In the entire project plan, multiple planned construction nodes will be divided according to the progress of the project. The construction content, construction personnel arrangement, and construction equipment arrangement of each planned construction node are different. Therefore, the number of planned personnel and the number of planned equipment at each planned construction node in the project plan can be counted first. The construction equipment of construction projects is usually large-scale equipment, and the use of large-scale equipment will basically not be different from the plan. Therefore, the number of construction equipment and the number of planned equipment are compared first. If the number of construction equipment and the number of planned equipment are different, it directly indicates that the corresponding planned construction node is not an actual construction progress node; and construction personnel may have temporary scheduling or leave, etc., so the difference between the number of construction personnel and the planned number of personnel can be calculated, and then the difference in quantity can be compared with the preset difference threshold to determine whether the corresponding planned construction node is an actual construction progress node.

Figure 3 The illustrated embodiment is described in detail.

[0104] Reference Figure 3 , combining the planned simulation model and the construction site image for comparison and analysis, and analyzing the progress status of the construction process includes the following steps:

[0111] 307, analyzing the progress status of the construction process based on the overlapped parts of the planned simulation model and the on-site 3D image.

[0112] The implementation principle of this embodiment is:

[0113] Generate a 3D image of the site based on the construction site image, and then overlap and compare the 3D image of the site at the actual construction node with the planned simulation model at the corresponding planned node. To ensure the perfect overlap between the 3D image and the simulation model, it is necessary to first mark the overlap reference point according to the preset reference point coordinates, and then overlap the 3D image and the simulation model with the overlap reference point. After the overlap, the model overlap rate of the planned simulation model and the site 3D image can be calculated, and the model overlap rate can be compared with the preset overlap rate threshold. If the model overlap rate is less than or equal to the overlap rate threshold, the construction process is in a normal progress state; if the model overlap rate is greater than the overlap rate threshold, it is necessary to further analyze the progress state of the construction process based on the overlapped part.

[0114] exist Figure 3 In step 307 of the illustrated embodiment, the progress status of the construction process is analyzed based on the surface area of ​​the non-overlapping parts of the planned simulation model and the on-site 3D image. Figure 4 The illustrated embodiment is described in detail.

[0115] Reference Figure 4 ,The analysis of the progress status of the construction process based on the overlap of the ,planned simulation model and the on-site 3D image includes the following steps:

[0116] 401, delete the overlapped parts between the planned simulation model and the on-site 3D image

[0118] 403, determine whether the residual surface area of ​​the model is larger than the surface area of ​​the image, if it is larger, execute step 404; if it is smaller, execute step 405.

[0119] 404. The analysis shows that the construction process is behind schedule.

[0120] 405. The analysis shows that the construction process is in the advanced progress state.

[0121] The implementation principle of this embodiment is:

[0122] Most of the planned simulation model and the on-site 3D image are buildings that need to be built for the construction project. Therefore, the overlapping parts of the planned simulation model and the on-site 3D image can be deleted, and then the surface areas of the remaining parts are compared. If the residual surface area of ​​the model of the planned simulation model is larger than the image surface area of ​​the on-site 3D image, it means that the on-site construction situation of the building has not reached the planned construction situation, so it can be analyzed that the construction process is in a backward progress state; if the residual surface area of ​​the model of the planned simulation model is smaller than the image surface area of ​​the on-site 3D image, it means that the on-site construction situation of the building has exceeded the planned construction situation, so it can be analyzed that the construction process is in an advanced progress state.

[0123] The present application also discloses a full-process tracking system for construction project management, which includes a model building module, a collection module, an image recognition module, an actual progress analysis module, a progress status determination module, and a performance point adjustment module. The image recognition module is connected to the collection module in communication, the actual progress analysis module is connected to the image recognition module in communication, the progress status determination module is connected to the model building module and the actual progress analysis module in communication, and the performance point adjustment module is connected to the progress status determination module in communication.

[0124] First, the construction simulation model is constructed according to the project plan through the model construction module, and then the construction site images during the construction process are collected through the acquisition module. After the image recognition module obtains the construction site images from the acquisition module, the number of construction personnel and construction equipment are obtained through the construction site images based on the image recognition technology. Therefore, the actual construction progress nodes of the construction process can be analyzed through the actual progress analysis module combined with the project plan. Then, the corresponding plan simulation model is extracted from the construction simulation model with the actual construction progress nodes through the progress status determination module, and the actual construction site images and the plan simulation model at the same time node are compared and analyzed to analyze the progress status of the construction process. Finally, the project score adjustment module adjusts the project leader's project score according to the progress status. Since the project score will affect the overall assessment of the project leader, the project leader with a low project score will be disqualified from the project leader. Therefore, the project score can be used to supervise the project leader and enable the project leader to control the project construction progress in a timely manner.

[0125] Specifically, the actual progress analysis module includes an identification unit, a statistical unit, a first judgment unit, a calculation unit and a second judgment unit, wherein the first judgment unit, the calculation unit and the identification unit are all communicatively connected to the statistical unit, the first judgment unit and the second judgment unit are both communicatively connected to the calculation unit, and a difference threshold is preset in the second judgment unit.

[0126] The planned construction nodes in the project plan are identified by the identification unit, and the planned number of personnel and the planned number of equipment at each planned construction node are counted by the statistical unit. Therefore, the number of construction equipment and the planned number of equipment are first compared by the first judgment unit. If the number of construction equipment and the planned number of equipment are different, it directly indicates that the corresponding planned construction node is not an actual construction progress node; and construction personnel may be temporarily scheduled or take leave, etc., so the difference between the number of construction personnel and the planned number of personnel can be calculated by the calculation unit, and then the difference in number can be compared with the preset difference threshold by the second judgment unit to determine whether the corresponding planned construction node is an actual construction progress node.

[0127] The progress status determination module specifically includes a model extraction submodule, a 3D image generation submodule, a model overlap submodule, a model calculation submodule and a status analysis submodule, wherein the model extraction submodule is communicatively connected with the model construction module, the 3D image generation submodule is communicatively connected with the acquisition module, the model overlap submodule is preset with reference point coordinates and is respectively communicated with the 3D image generation submodule, the model calculation submodule, the model extraction submodule and the model construction module, and the status analysis submodule is preset with an overlap rate threshold and is respectively communicated with the model extraction submodule and the model calculation submodule.

[0128] The model extraction submodule extracts the corresponding planned simulation model from the construction simulation model according to the actual construction progress node. The 3D image generation submodule generates a 3D image of the site according to the construction site image. The model overlap submodule then overlaps and compares the 3D image of the site at the actual construction node with the planned simulation model at the corresponding planned node. Then, the model calculation submodule can calculate the model overlap rate of the planned simulation model and the site 3D image. Finally, the state analysis submodule compares the model overlap rate with the preset overlap rate threshold. If the model overlap rate is less than or equal to the overlap rate threshold, the construction process is in a normal progress state; if the model overlap rate is greater than the overlap rate threshold, it is necessary to further analyze the progress state of the construction process based on the overlapped part.

[0129] The state analysis submodule includes a deletion unit, a surface area calculation unit and a state analysis unit, wherein the deletion unit is connected to the model overlap submodule, the surface area calculation unit is connected to the deletion unit, and the state analysis unit is connected to the surface area calculation unit. The overlapping part of the planned simulation model and the on-site 3D image is deleted by the deletion unit, and the surface area calculation unit calculates the surface area of ​​the remaining part of the planned simulation model and the on-site 3D image, and finally the state analysis unit determines the construction progress according to the surface area of ​​the remaining part of the planned simulation model and the on-site 3D image.

[0130] If the residual surface area of ​​the model of the planned simulation model is larger than the image surface area of ​​the on-site 3D image, it means that the on-site construction situation of the building has not reached the planned construction situation, so it can be analyzed that the construction process is in a state of lagging progress; if the residual surface area of ​​the model of the planned simulation model is smaller than the image surface area of ​​the on-site 3D image, it means that the on-site construction situation of the building has exceeded the planned construction situation, so it can be analyzed that the construction process is in a state of ahead of schedule.

[0131] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
