Description

Technical Field

[0001] This invention belongs to the field of construction management technology, and in particular relates to a construction management method and system for prefabricated office buildings. Background Technology

[0002] Prefabricated office buildings have advantages such as short construction period and high construction efficiency. However, at the same time, the construction of prefabricated office buildings puts forward higher requirements for the collaborative management of different construction departments. Specifically, the invention patent application "A Method and System for Construction Management of Prefabricated Building Installation" introduces an intelligent collaborative operation management module that can accurately grasp the status information of personnel and equipment on the construction site in real time, and optimize task allocation and operation sequence based on this information, thereby further improving the efficiency of construction.

[0003] In the construction management of prefabricated office buildings, existing technical solutions neglect the safety risks between different construction operations. When multiple construction projects are carried out simultaneously, the probability of safety risks is greater. Therefore, if the reliability of monitoring and handling safety risks during simultaneous construction projects is not considered to generate differentiated construction plans, potential construction safety hazards may arise.

[0004] To address the aforementioned technical problems, this application provides a construction management method and system for prefabricated office buildings. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted: Firstly, this application provides a construction management method for prefabricated office buildings, specifically including: S1 is based on the construction projects in different construction areas of the prefabricated office building. The safety risk points of the construction area are identified. When the reliability of the monitoring and management of the safety risk points of the construction area meets the requirements, the next step is initiated. S2 determines the construction processing time when the construction project meets the construction conditions requirements based on the construction conditions requirements of the unconstructed projects in the construction area, and determines the associated construction projects among the unconstructed projects in combination with the correlation between the unconstructed projects and other unconstructed projects. S3, based on the construction equipment and construction location of the associated construction project, determines the monitoring impact of the associated construction project on the safety risk points of the construction project, and determines the available construction projects in the associated construction project based on the monitoring impact. S4 determines the construction optimization treatment plan for the construction area by using the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, combined with the distribution data of the monitoring devices in the construction area.

[0006] The beneficial effects of this invention are as follows: Based on the monitoring impact, the available construction projects among the associated construction projects are determined. This enables the determination of the impact on the monitoring reliability of safety risks by analyzing the obstruction of safety risk hazard points of available construction projects in the monitoring device during the construction process of associated construction projects. This avoids the technical problem of unsatisfactory monitoring reliability of safety risks caused by simultaneous construction, and improves the reliability of monitoring and processing.

[0007] By using the safety risk hazard points of available construction projects and the distribution data of these safety risk hazard points, as well as the distribution data of monitoring devices in the construction area, an optimized construction treatment plan for the construction area is determined. This plan not only takes into account the differences in the number of safety risk hazard points monitored by different monitoring devices during simultaneous construction, leading to differences in the reliability of safety risk monitoring, but also considers the differences in the occlusion risks during the construction process caused by differences in the distribution data of different safety risk hazard points. This ensures the reliability of safety risk monitoring for both unconstructed and constructed projects that are being constructed simultaneously.

[0008] A further technical solution is that the safety risk points in the construction area are determined based on the construction sites where safety accidents have occurred during the construction project.

[0009] A further technical solution involves ensuring that the reliability of monitoring and management of safety risk points in the construction area meets the requirements, specifically including: Based on the safety risk points in the construction area, determine the number of safety risk points in different monitoring devices in the construction area; Based on the number of safety risk points in different monitoring devices, determine whether the reliability of monitoring and management of safety risk points in the construction area meets the requirements.

[0010] A further technical solution is that when the number of monitoring devices with potential safety risks exceeds a preset threshold for the number of potential safety risks, it is determined that the reliability of monitoring and management of potential safety risks in the construction area does not meet the requirements.

[0011] A further technical solution is that when the reliability of monitoring and management of safety risk points in the construction area does not meet the requirements, it is impossible to carry out simultaneous construction of other unconstructed projects while the construction project is underway.

[0012] A further technical solution is that the monitoring device is a video surveillance device.

[0013] A further technical solution involves determining the construction optimization treatment scheme for the construction area as follows: Based on the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, the number of safety risk hazard points in different monitoring devices is determined; Based on the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, determine the number of safety risk hazard points that are obstructed during the construction process in the construction area; Based on the maximum number of safety risk points in different monitoring devices and the average number of safety risk points in the construction area that are obstructed during construction, the adaptation deviation coefficient of the available construction projects is determined, and the construction optimization treatment plan for the construction area is determined based on the adaptation deviation coefficient.

[0014] A further technical solution involves determining a construction optimization treatment scheme for the construction area based on the adaptation deviation coefficient, specifically including: The construction area is optimized by using the available construction project with the smallest adaptation deviation coefficient.

[0015] Secondly, the present invention provides a computer system comprising: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the above-described method for construction management of prefabricated office buildings when running the computer program.

[0022] Example 1 To solve the above problems, according to one aspect of the present invention, such as Figure 1 As shown, a construction management method for prefabricated office buildings is provided, which specifically includes: S1 is based on the construction projects in different construction areas of the prefabricated office building. The safety risk points of the construction area are identified. When the reliability of the monitoring and management of the safety risk points of the construction area meets the requirements, the next step is initiated. Furthermore, the safety risk points in the construction area are determined based on the construction sites where safety accidents have occurred during the construction project.

[0023] Specifically, such as Figure 2 As shown, the reliability of monitoring and management of safety risk points in the construction area meets the requirements, specifically including: Based on the safety risk points in the construction area, determine the number of safety risk points in different monitoring devices in the construction area; Based on the number of safety risk points in different monitoring devices, determine whether the reliability of monitoring and management of safety risk points in the construction area meets the requirements.

[0024] Furthermore, if the number of monitoring devices with potential safety risks exceeds the preset threshold for the number of potential safety risks, then it is determined that the reliability of monitoring and management of potential safety risks in the construction area does not meet the requirements.

[0025] It should be noted that if the reliability of monitoring and management of safety risk points in the construction area does not meet the requirements, it is impossible to carry out simultaneous construction of other unconstructed projects while the construction project is underway.

[0026] In another possible embodiment, determining that the reliability of monitoring and management of safety risk points in the construction area meets the requirements specifically includes: Based on the safety risk points in the construction area, the number of safety risk points in the construction area is determined. When the number of safety risk points in the construction area exceeds a preset threshold, the reliability of monitoring and management of the safety risk points in the construction area is determined to be unsatisfactory. When the number of potential safety risks in the construction area is not greater than the preset threshold for the number of potential risks: Based on the distribution data of safety risk points in the construction area, the number of safety risk points in different monitoring devices in the construction area is determined. When there is a monitoring device with a number of safety risk points greater than the preset threshold for the number of safety risk points, it is determined that the reliability of monitoring and management of safety risk points in the construction area does not meet the requirements. When there are no monitoring devices with a number of potential safety risks exceeding the preset threshold: The number of monitoring devices with potential safety risks is obtained. If the number of monitoring devices with potential safety risks is insufficient, it is determined that the reliability of monitoring and management of potential safety risks in the construction area does not meet the requirements. When the number of monitoring devices at points with potential safety risks meets the requirements: Based on the number of safety risk points in different monitoring devices and the image size of the safety risk points in different monitoring devices, the identification risk coefficient of different monitoring devices is determined. When there are monitoring devices whose identification risk coefficient does not meet the requirements, it is determined that the monitoring and management reliability of the safety risk points in the construction area does not meet the requirements. When no monitoring device exists that can identify risk factors that do not meet the requirements: Based on the risk identification coefficient of different monitoring devices and the number of monitoring devices, the monitoring and management reliability coefficient of the construction area is determined. Based on the monitoring and management reliability coefficient, it is determined whether the monitoring and management reliability of the safety risk points in the construction area meets the requirements.

[0027] Furthermore, when the monitoring and management reliability coefficient is within the preset management reliability coefficient range, it is determined that the monitoring and management reliability of the safety risk hazard points in the construction area does not meet the requirements.

[0028] S2 determines the construction processing time when the construction project meets the construction conditions requirements based on the construction conditions requirements of the unconstructed projects in the construction area, and determines the associated construction projects among the unconstructed projects in combination with the correlation between the unconstructed projects and other unconstructed projects. Specifically, the construction conditions for the unconstructed projects are based on the flatness of the site, the completion of water and electricity pipeline construction, the completion of cement curing, and the completion of prefabricated component installation.

[0029] Specifically, such as Figure 3 As shown, the method for determining the associated construction projects among the unconstructed projects is as follows: The construction overlap coefficient of the unconstructed project is determined by the ratio of the construction processing time when the construction project meets the construction conditions to the total construction time of the construction project. Based on the correlation between the unconstructed project and other unconstructed projects, determine the construction conditions to be achieved after the completion of the unconstructed project, and the overlap between the construction condition requirements of the unconstructed project and other different unconstructed projects. Use the overlap to determine the number of projects affected by the unconstructed project. Based on the number of affected projects and the construction overlap coefficient, the associated construction projects among the unconstructed projects are determined.

[0030] Furthermore, the number of affected projects is determined based on the number of unconstructed projects that meet the construction condition requirements.

[0031] It should be noted that, based on the number of affected projects and the construction overlap coefficient, the related construction projects among the unconstructed projects are determined, specifically including: When the construction overlap coefficient is greater than the preset overlap coefficient threshold, it is determined that the unconstructed project does not belong to the associated construction project. When the construction overlap coefficient is not greater than the preset overlap coefficient threshold, and when the number of projects affected by the unconstructed project is greater than the preset number of affected projects threshold, the unconstructed project is determined to be a related construction project; when the number of projects affected by the unconstructed project is not greater than the preset number of affected projects threshold, the unconstructed project is determined not to be a related construction project.

[0032] Optionally, the method for determining the associated construction projects among the unconstructed projects is as follows: S21. The construction overlap coefficient of the unconstructed project is determined by the ratio of the construction processing time when the construction project meets the construction conditions to the total construction time of the construction project. S22 determines the construction conditions to be achieved after the completion of the unconstructed project based on the relationship between the unconstructed project and other unconstructed projects, the overlap of the construction conditions required by the unconstructed project with the construction conditions of different other unconstructed projects, and determines the construction progress impact coefficient of the unconstructed project based on the number of overlaps between the construction conditions and construction conditions required by the unconstructed project with different unconstructed projects. S23 determines the correlation coefficient of the unconstructed project based on the ratio of the construction progress influence coefficient to the construction overlap coefficient, and uses the correlation coefficient to determine the associated construction project among the unconstructed projects.

[0033] Optionally, when the correlation coefficient of the unconstructed project is greater than a preset correlation coefficient threshold, the unconstructed project is determined to be a related construction project.

[0034] Optionally, step S21 above includes the following: S211 If, based on the construction condition requirements of the unconstructed project, it is determined that the construction condition requirements of the construction project cannot be met during construction processing, then it is determined that the unconstructed project is not a related construction project of the construction project. When the construction condition requirements of the construction project can be met during construction processing, proceed to the next step. S212 Based on the construction processing time when the construction project meets the construction conditions, if the construction processing time does not meet the requirements, then it is determined that the unconstructed project is not a related construction project of the construction project. When the construction processing time meets the requirements, proceed to the next step. S213 determines the construction overlap coefficient of the unconstructed project by the ratio of the construction processing time when the construction project meets the construction conditions to the total construction time of the construction project. When the construction overlap coefficient of the unconstructed project is less than the preset overlap coefficient threshold, proceed to step S22. When the construction overlap coefficient of the unconstructed project is not less than the preset overlap coefficient threshold, it is determined that the unconstructed project does not belong to the associated construction project of the construction project. Optionally, step S22 above includes the following: S221 Based on the correlation between the unconstructed project and other unconstructed projects, determine the construction conditions achieved after the completion of the unconstructed project and the overlap of construction condition requirements with different other unconstructed projects. If the number of projects affected by the unconstructed project is greater than a preset threshold for the number of affected projects, then the unconstructed project is determined to be a related construction project. If the number of projects affected by the unconstructed project is not greater than the preset threshold for the number of affected projects, then proceed to step S222. S222 Determine the construction condition correlation coefficient between different unconstructed projects based on the number of overlaps between construction conditions and construction condition requirements. If there are unconstructed projects with a construction condition correlation coefficient greater than the preset correlation coefficient threshold, proceed to step S223. If there are no unconstructed projects with a construction condition correlation coefficient greater than the preset correlation coefficient threshold, proceed to step S224. S223 When the number of unconstructed projects with a construction condition correlation coefficient greater than the preset correlation coefficient threshold meets the requirements, the unconstructed projects are determined to be associated construction projects. When the number of unconstructed projects with a construction condition correlation coefficient greater than the preset correlation coefficient threshold does not meet the requirements, proceed to step S224. S224 determines the construction progress impact coefficient of the unconstructed project based on the number of overlaps in construction conditions and construction condition requirements between the unconstructed project and the project. When the construction progress impact coefficient of the unconstructed project is greater than the preset construction progress impact coefficient threshold, the unconstructed project is determined to be an associated construction project. When the construction progress impact coefficient of the unconstructed project is not greater than the preset construction progress impact coefficient threshold, the process proceeds to step S23.

[0035] S3, based on the construction equipment and construction location of the associated construction project, determines the monitoring impact of the associated construction project on the safety risk points of the construction project, and determines the available construction projects in the associated construction project based on the monitoring impact. Furthermore, the impact of the associated construction project on the monitoring of the safety risk points of the construction project is determined based on the construction equipment and construction location during the construction process of the associated construction project, and the degree of obstruction of the safety risk points of the construction project in the monitoring device.

[0036] Specifically, such as Figure 4 As shown, the method for determining the available construction projects among the associated construction projects is as follows: Based on the monitoring impact, determine the extent to which the associated construction project obstructs the monitoring device from the safety risk points of the construction project during the construction process; Based on the occlusion situation, the occlusion duration for different safety risk points is determined; By utilizing the duration of obstruction at different safety risk points, it can be determined whether the associated construction project is a usable construction project.

[0037] Furthermore, the duration of the obstruction is determined based on the construction equipment and construction time of the construction site that obstructs the safety risk hazard point.

[0038] It should be noted that when the number of safety risk points in the construction project whose occlusion duration exceeds the preset occlusion duration threshold is greater than the preset value of the number of risk points, the associated construction project is determined not to be an available construction project.

[0039] In another possible embodiment, the method for determining the available construction projects in the associated construction projects is as follows: Based on the monitoring impact, determine the extent to which the associated construction project obstructs the monitoring device from the safety risk points of the construction project during the construction process; Based on the aforementioned occlusion situation, determine the number of potential safety risks associated with the occlusion. The number of potential safety risks caused by obstruction is used to determine whether the associated construction project is a usable construction project.

[0040] Furthermore, if the number of potential safety hazards caused by obstruction exceeds a preset threshold for the number of obstruction hazards, then the associated construction project is determined not to be an available construction project.

[0041] S4 determines the construction optimization treatment plan for the construction area by using the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, combined with the distribution data of the monitoring devices in the construction area.

[0042] Furthermore, the monitoring device is a video surveillance device.

[0043] Specifically, the method for determining the construction optimization treatment plan for the construction area is as follows: Based on the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, the number of safety risk hazard points in different monitoring devices is determined; Based on the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, determine the number of safety risk hazard points that are obstructed during the construction process in the construction area; Based on the number of safety risk points in different monitoring devices and the number of safety risk points that are obstructed during the construction process, an optimized construction treatment plan for the construction area is determined.

[0044] Furthermore, the number of potential safety risks in the construction area during construction is determined based on the situation where construction machinery or construction sites obstruct the monitoring of potential safety risks during the construction of the construction project and other available construction projects.

[0045] It should be noted that, based on the number of safety risk points detected by different monitoring devices and the number of safety risk points obstructed during construction, an optimized construction treatment plan for the construction area is determined, specifically including: When the number of monitoring devices with potential safety risks exceeds the preset threshold for the number of risk points, it is determined that the available construction projects cannot be used to optimize the construction of the construction area. When there are no monitoring devices that detect safety risks exceeding a preset threshold, the available construction project with the fewest obstructed safety risks in the construction area is selected as the target construction project, and the construction optimization process for the construction area is carried out using the target construction project.

[0046] It should be noted that the optimization of the construction area using the target construction project specifically includes: When the construction conditions required for the target construction project are met, the target construction project and the construction plan will be carried out simultaneously in the construction area.

[0047] In another possible embodiment, the method for determining the construction optimization treatment scheme for the construction area is as follows: Based on the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, the number of safety risk hazard points in different monitoring devices is determined; Based on the safety risk hazard points of the available construction projects and the distribution data of the safety risk hazard points of the construction projects, determine the number of safety risk hazard points that are obstructed during the construction process in the construction area; Based on the maximum number of safety risk points in different monitoring devices and the average number of safety risk points in the construction area that are obstructed during construction, the adaptation deviation coefficient of the available construction projects is determined, and the construction optimization treatment plan for the construction area is determined based on the adaptation deviation coefficient.

[0048] Furthermore, based on the adaptation deviation coefficient, a construction optimization treatment plan for the construction area is determined, specifically including: The construction area is optimized by using the available construction project with the smallest adaptation deviation coefficient.
