Description

Technical Field

[0001] The present invention relates to the technical field of construction management, and in particular to a method for dynamically tracking and adjusting the construction progress of a construction project based on the Internet of Things. Background Art

[0002] Construction projects refer to the general term for various types of buildings and engineering facilities that provide the material and technical basis for human life and production. They are organized, purposeful, large-scale economic activities. They are engineering projects that form comprehensive production capacity or exert engineering benefits in the process of fixed asset reproduction.

[0003] The construction progress of a construction project refers to the comparison between the actual construction status of a construction project and the predetermined plan within a certain period of time. The construction progress directly affects the quality, cost and construction period of the project. Reasonable construction progress management can ensure that the project is completed on time and avoid additional costs or contract breaches caused by delays in the construction period.

[0004] In the prior art, the planning and adjustment of the construction progress usually rely on the judgment and experience of project managers. The process of this method usually involves considerations at multiple levels, including but not limited to the reasonable allocation of resources, the reasonable arrangement of processes, etc., and through real-time monitoring of project progress, potential delay risks are discovered in a timely manner, and then corresponding adjustments are made to ensure that the construction period can be completed on time. However, the manual planning and adjustment method relies too much on the professional knowledge and historical experience of managers, is not scientific enough, and has limited flexibility. Based on this, a method for dynamic tracking and adjustment of construction progress of construction projects based on the Internet of Things is provided to avoid the adverse effects of manual planning of construction progress. Summary of the invention

[0005] The purpose of the present invention is to provide a method for dynamically tracking and adjusting the construction progress of a construction project based on the Internet of Things to solve the following technical problems:

[0006] The planning and adjustment of construction progress usually rely on the judgment and experience of project managers. This method usually involves multiple levels of consideration, including but not limited to the reasonable allocation of resources, the reasonable arrangement of processes, etc., and through real-time monitoring of project progress, potential delay risks can be discovered in a timely manner, and corresponding adjustments can be made to ensure that the construction period can be completed on time. However, the manual planning and adjustment method relies too much on the professional knowledge and historical experience of managers, is not scientific enough, and has limited flexibility.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A method for dynamically tracking and adjusting the construction progress of a construction project based on the Internet of Things comprises the following steps:

[0009] Within the preset construction period [Tsta, Tend], n time nodes are set at preset time intervals, the time period between two adjacent time nodes is taken as a sub-period, and the construction progress of the construction project is obtained at the time node at the end of the sub-period;

[0010] Determine the sub-period i where the current time is located, calculate the construction progress difference Di=di-di-1, where di represents the construction progress at the time node at the end of the sub-period i, and when the construction progress difference Di<Ri, it is marked as an adjustment state, and Ri represents the preset construction progress difference threshold corresponding to the sub-period i;

[0011] Determine the construction progress difference threshold Ri in the next sub-period i+1 adjacent to the sub-period i +1 , let the construction progress difference threshold Ri +1 =Ri +1 +(Ri-Di), adjust the construction efficiency Pi within the sub-period i+1 +1 =Ri +1 / S, S indicates the preset working time;

[0012] The process of determining the construction progress difference threshold specifically includes:

[0013] Step 1: Divide the construction project into n-1 sub-projects evenly, one sub-project corresponds to one sub-period, and determine the complexity K of the sub-projects, calculate the average complexity Kavg, and calculate the standard progress C'=C*(K / Kavg), C=1 / (n-1);

[0014] Step 2: Repeat step 1 to determine the complexity Ksec and standard progress C' of the sub-project, and calculate the complexity difference KCZ = |Ksec-K| and the standard progress difference CCZ = |C''-C'|;

[0015] Step 3: Set the complexity difference threshold KCZ' and the standard progress difference threshold CCZ'. When the complexity difference KCZ≥KCZ' and / or the standard progress difference CCZ≥KCZ', repeat the above steps until the complexity difference is less than the complexity difference threshold and the standard progress difference is less than the standard progress difference threshold, and use the standard progress at this time as the construction progress difference threshold.

[0016] As a further solution of the present invention: the process of determining the complexity K of the sub-item specifically includes:

[0017] Determine the initial complexity of each sub-project relative to other sub-projects by using the hierarchical analysis method. When the initial complexity of sub-project a is higher than that of sub-project b, then sub-project a is more complex than sub-project b. Then sort the sub-projects in the order of initial complexity. The higher the initial complexity, the higher the ranking of the corresponding sub-project, and obtain the initial sorting.

[0018] Determine the sorting position A of the sub-item in the initial sorting, calculate the first complexity kfir=ε / A, ε is a preset coefficient, map the first complexity to a value interval (0, 1], and use the value after mapping the first complexity kfir to the value interval (0, 1] as the complexity K of the sub-item.

[0019] As a further solution of the present invention: the process of determining the standard progress further includes the following steps:

[0020] Calculate the total standard progress Ctot. When the total standard progress Ctot≠1, calculate the adjustment factor Rg=Cg' / Ctot, and let Cg'=Rg*Cg'.

[0021] As a further solution of the present invention: in the process of adjusting the construction efficiency in the sub-period i+1, a construction efficiency threshold P' is set, and when the construction efficiency Pi +1 >P', perform the following steps:

[0022] Let the construction efficiency P in the sub-period i+1 = P', and calculate the remaining construction progress Dsy = (Pi +1 -P')S;

[0023] Determine the next sub-period i+2 adjacent to the sub-period i+1, and let the construction progress threshold Ri corresponding to the sub-period i+2 be +2 =Ri +2 +Dsy, and determine the construction efficiency Pi within the sub-period i+2 +2 , and repeat the above steps until the remaining construction progress Dsy after adjusting the construction progress threshold within a sub-period is ≤ 0.

[0024] As a further solution of the present invention: in the process of adjusting the construction progress threshold within a sub-cycle, when the sub-cycle H belongs to the sub-cycle interval [n-5, n-1] and the construction progress threshold of the sub-cycle H is adjusted, an early warning message is sent to remind the staff.

[0025] As a further solution of the present invention: when the complexity difference and standard progress difference calculated for the Docth time still do not satisfy the condition that the complexity difference is less than the complexity difference threshold and the standard progress difference is less than the standard progress difference threshold, the standard progress calculated for the Docth time is used as the construction progress difference threshold, and Doc represents the preset maximum number of iterations.

[0026] As a further solution of the present invention: in the step S1, the process of obtaining the construction progress of the construction project at the time node at the end of the sub-cycle specifically includes:

[0027] At the time point at the end of the sub-period, determining the vertical distance between the reference point on the construction project and a reference line, the reference line passing through the starting point of the construction project and being parallel to the horizontal plane;

[0028] The average vertical distance L between the reference point and the reference line is calculated, and the construction progress d=L / Ltot is calculated, where Ltot represents a preset average distance threshold.

[0029] As a further solution of the present invention: the distance between the reference point and the reference line is obtained based on a sensor.

[0030] Beneficial effects of the present invention: In the present invention, the preset construction period is first divided into several sub-periods, and the construction progress of the construction project is obtained at the time node at the end of each sub-period, which is the data basis for subsequent adjustments. The purpose of dividing the construction period into several sub-periods is to consider whether the construction progress within a sub-period has achieved the target in the subsequent process, so as to avoid errors in the overall adjustment. A sub-period is one day, and the construction period is determined according to the actual situation; then, the sub-period i in which the current time is located is determined, the difference in construction progress within sub-period i is calculated, and whether it is in an adjustment state is determined according to the difference in construction progress and a preset construction progress difference threshold; it can be understood that the difference in construction progress reflects the actual progress completed within a sub-period, and the difference in construction progress threshold represents the progress that should be completed within sub-period i under theoretical circumstances. It is worth noting that the difference in construction progress threshold is determined based on the complexity of the sub-projects, and the sub-projects are divided according to the construction period, such as Ten-day construction period, one sub-cycle is one day, and the initial sub-project is 1 / 10, that is, 1 / 10 of the construction project that needs to be completed in one sub-cycle (one day). It is worth noting that different sub-projects are different in different sub-cycles, and different sub-projects may also be different in complexity. Therefore, it is necessary to adjust the progress that should be completed in the sub-cycle according to the complexity of the sub-project. The more complex the sub-project, the less progress should be completed in a sub-cycle. Therefore, the progress that needs to be completed in the sub-cycle is adjusted according to the complexity of the sub-project. At the same time, after adjusting the progress that needs to be completed in the sub-cycle, the complexity of the sub-project will change again, so it is necessary to iterate, and adjust the progress that needs to be completed in the sub-cycle again, until the complexity difference and the standard progress difference meet expectations; Finally, adjust the construction progress difference threshold in the next sub-cycle i+1, that is, adjust the progress that needs to be completed in the next sub-cycle, and adjust the work efficiency, so as to make up for the progress difference in the previous sub-cycle. The present invention plans the construction progress in each sub-cycle by the complexity of the sub-project, and when the actual construction progress is lower than expected, flexibly adjusts the construction efficiency in the subsequent sub-cycle to avoid the situation of construction period delay. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Figure 1 The present invention is a flow chart of a method for dynamically tracking and adjusting the construction progress of a construction project based on the Internet of Things. DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 As shown, the present invention is a method for dynamically tracking and adjusting the construction progress of a construction project based on the Internet of Things, comprising the following steps:

[0035] Within the preset construction period [Tsta, Tend], n time nodes are set at preset time intervals, the time period between two adjacent time nodes is taken as a sub-period, and the construction progress of the construction project is obtained at the time node at the end of the sub-period;

[0036] Determine the sub-period i where the current time is located, calculate the construction progress difference Di=di-di-1, where di represents the construction progress at the time node at the end of the sub-period i, and when the construction progress difference Di<Ri, it is marked as an adjustment state, and Ri represents the preset construction progress difference threshold corresponding to the sub-period i;

[0037] Determine the construction progress difference threshold Ri in the next sub-period i+1 adjacent to the sub-period i +1 , let the construction progress difference threshold Ri +1 =Ri +1 +(Ri-Di), adjust the construction efficiency Pi within the sub-period i+1 +1 =Ri +1 / S, S indicates the preset working time;

[0038] The process of determining the construction progress difference threshold specifically includes:

[0039] Step 1: Divide the construction project into n-1 sub-projects evenly, one sub-project corresponds to one sub-period, and determine the complexity K of the sub-projects, calculate the average complexity Kavg, and calculate the standard progress C'=C*(K / Kavg), C=1 / (n-1);

[0040] Step 2: Repeat step 1 to determine the complexity Ksec and standard progress C' of the sub-project, and calculate the complexity difference KCZ = |Ksec-K| and the standard progress difference CCZ = |C''-C'|;

[0041] Step 3: Set the complexity difference threshold KCZ' and the standard progress difference threshold CCZ'. When the complexity difference KCZ≥KCZ' and / or the standard progress difference CCZ≥KCZ', repeat the above steps until the complexity difference is less than the complexity difference threshold and the standard progress difference is less than the standard progress difference threshold, and use the standard progress at this time as the construction progress difference threshold.

[0042] It should be noted that the preset construction period is first divided into several sub-periods, and the construction progress of the construction project is obtained at the end of each sub-period. This is the data basis for subsequent adjustments. The purpose of dividing the construction period into several sub-periods is to consider whether the construction progress within a sub-period has achieved the target in the subsequent process to avoid errors in the overall adjustment. A sub-period is one day, and the construction period is determined based on the actual situation; then, the sub-period i in which the current time is located is determined, the difference in construction progress within sub-period i is calculated, and whether it is in an adjustment state is determined based on the construction progress difference and the preset construction progress difference threshold; it can be understood that the construction progress difference reflects the actual progress completed within a sub-period, and the construction progress difference threshold represents the progress that should be completed within sub-period i under theoretical circumstances. It is worth noting that the construction progress difference threshold is determined based on the complexity of the sub-project, and the sub-project is divided according to the construction period, such as a ten-day Construction period, one sub-cycle is one day, and the initial sub-project division is 1 / 10, that is, 1 / 10 of the construction project that needs to be completed in one sub-cycle (one day). It is worth noting that the sub-projects in different sub-cycles are different, and the complexity of different sub-projects may also be different. Therefore, it is necessary to adjust the progress that should be completed in the sub-cycle according to the complexity of the sub-project. The more complex the sub-project, the less progress should be completed in a sub-cycle. Therefore, the progress that needs to be completed in the sub-cycle is adjusted according to the complexity of the sub-project. At the same time, after adjusting the progress that needs to be completed in the sub-cycle, the complexity of the sub-project will change again, so it is necessary to iterate and adjust the progress that needs to be completed in the sub-cycle again until the complexity difference and the standard progress difference meet expectations; finally, adjust the construction progress difference threshold in the next sub-cycle i+1, that is, adjust the progress that needs to be completed in the next sub-cycle, and adjust the work efficiency, so as to make up for the progress difference in the previous sub-cycle.

[0043] In another preferred embodiment of the present invention, the process of determining the complexity level K of the sub-item specifically includes:

[0044] Determine the initial complexity of each sub-project relative to other sub-projects by using the hierarchical analysis method. When the initial complexity of sub-project a is higher than that of sub-project b, then sub-project a is more complex than sub-project b. Then sort the sub-projects in the order of initial complexity. The higher the initial complexity, the higher the ranking of the corresponding sub-project, and obtain the initial sorting.

[0045] Determine the sorting position A of the sub-item in the initial sorting, calculate the first complexity kfir=ε / A, ε is a preset coefficient, map the first complexity to a value interval (0, 1], and use the value after mapping the first complexity kfir to the value interval (0, 1] as the complexity K of the sub-item.

[0046] It is worth noting that the analytic hierarchy process (AHP) is a multi-criteria decision analysis method. By constructing a comparison matrix and performing weight calculation, it can decompose complex multi-factor problems into several levels, compare the elements in each level, and finally obtain the relative weight or importance of each element. In this scheme, the analytic hierarchy process can be used to systematically evaluate the complexity of each sub-project relative to other sub-projects, thereby providing a scientific basis for subsequent resource allocation and schedule scheduling; the initial complexity of the sub-project is calculated by the sorting position A to obtain the first complexity kfir. Because the range of the sorting position A can be large, in order to make the complexity K within a controllable range and prevent the complexity value obtained by the original calculation from being too large or too small, the first complexity kfir is mapped to the value within the value interval (0, 1] as the complexity K of the sub-project.

[0047] In another preferred embodiment of the present invention, the process of determining the standard progress further includes the following steps:

[0048] Calculate the total standard progress Ctot. When the total standard progress Ctot≠1, calculate the adjustment factor Rg=Cg' / Ctot, and let Cg'=Rg*Cg'.

[0049] In another preferred embodiment of the present invention, during the process of adjusting the construction efficiency in the sub-period i+1, a construction efficiency threshold P' is set. +1 >P', perform the following steps:

[0050] Let the construction efficiency P in the sub-period i+1 = P', and calculate the remaining construction progress Dsy = (Pi +1 -P')S;

[0051] Determine the next sub-period i+2 adjacent to the sub-period i+1, and let the construction progress threshold Ri corresponding to the sub-period i+2 be +2 =Ri +2 +Dsy, and determine the construction efficiency Pi within the sub-period i+2 +2 , and repeat the above steps until the remaining construction progress Dsy after adjusting the construction progress threshold within a sub-period is ≤ 0.

[0052] It should be noted that the construction efficiency Pi +1 Represents the required work efficiency in sub-period i+1. If Pi +1 Exceeding the preset threshold value P' means that higher construction efficiency is required to complete the planned tasks, but excessively high construction efficiency may bring various risks, such as insufficient resources, quality decline, worker fatigue, etc. Therefore, setting P' can be used as a safety limit to avoid the occurrence of these risks; by limiting the construction efficiency within a reasonable range, ensure that the safety of the construction process and the quality of the project are not affected by excessive efficiency; by adjusting and allocating the remaining construction progress, ensure that the construction load of each sub-cycle is more balanced, and avoid the adverse effects of local progress imbalance.

[0053] In another preferred embodiment of the present invention, during the process of adjusting the construction progress threshold within a sub-cycle, when the sub-cycle H belongs to the sub-cycle interval [n-5, n-1] and the construction progress threshold of the sub-cycle H is adjusted, an early warning message is sent to remind the staff.

[0054] It should be noted that the sub-cycle interval [n-5, n-1] represents the stage when the project is nearing its end. The room for error in project management becomes smaller, and any deviation in the progress may cause the project to be delayed or fail to be completed as expected. By setting up an early warning mechanism within this interval, potential risks can be discovered and dealt with in a timely manner to avoid delays in the overall construction period due to adjustments in the final stage. By sending early warning information, project managers can intervene and make adjustments earlier to prevent potential problems caused by progress adjustments from worsening in the final stage.

[0055] In another preferred embodiment of the present invention, when the complexity difference and standard progress difference calculated for the Docth time still do not satisfy the condition that the complexity difference is less than the complexity difference threshold and the standard progress difference is less than the standard progress difference threshold, the standard progress calculated for the Docth time is used as the construction progress difference threshold, and Doc represents the preset maximum number of iterations.

[0056] It is understandable that in a complex project management process, in some cases, even after multiple iterations, the complexity difference and the standard progress difference may still not meet the preset threshold requirements. If the maximum number of iterations Doc is not set, the calculation process may fall into an infinite loop, resulting in a sharp increase in management and calculation costs; when the standard progress difference still does not meet the requirements after multiple iterations, it means that further adjustments may have limited effect, or there are irreconcilable differences in the model itself. At this time, using the Docth standard progress as the construction progress difference threshold, although not necessarily the optimal solution, is usually the most feasible solution under complex conditions; when the standard progress difference still fails to meet expectations after repeated adjustments, directly using the Docth calculation result can avoid further complication of the problem, so that subsequent construction plans can be carried out under relatively stable conditions.

[0057] In another preferred embodiment of the present invention, in step S1, the process of obtaining the construction progress of the construction project at the time node at the end of the sub-cycle specifically includes:

[0058] At the time point at the end of the sub-period, determining the vertical distance between the reference point on the construction project and a reference line, the reference line passing through the starting point of the construction project and being parallel to the horizontal plane;

[0059] The average vertical distance L between the reference point and the reference line is calculated, and the construction progress d=L / Ltot is calculated, where Ltot represents a preset average distance threshold.

[0060] It is worth noting that the average distance threshold Ltot is determined based on actual conditions. It represents the average vertical distance between the reference point and the reference line when the construction project is completed. The reference point is different at the end of each sub-cycle. The position of the reference point is determined based on actual conditions.

[0061] In another preferred embodiment of the present invention, the distance between the reference point and the reference line is acquired based on a sensor.

[0062] It is worth noting that sensors, especially laser rangefinders, ultrasonic sensors or laser scanners, can provide very high measurement accuracy. Compared with traditional manual measurement methods, sensors can more accurately capture the vertical distance between the reference point and the reference line, reducing human errors.

[0063] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
