Description

Technical Field

[0001] The present invention relates to the technical field of construction management, and in particular to an intelligent construction management system based on BIM. Background Art

[0002] With the advancement and development of science and technology, and in the context of the digital transformation of various industries, the digital development of the construction industry has gradually unfolded. The construction management system is a network platform that coordinates, optimizes, and communicates various relevant information data of construction projects. Combined with BIM technology, it can integrate relevant information of various projects through parameter models, providing a basis for collaborative work for design teams and all construction entities including building operators, and plays an important role in improving production efficiency, saving costs, and shortening construction periods. The construction management technology in the existing technology cannot analyze the construction process data in real time, resulting in unreasonable allocation of construction tasks and delays in construction tasks.

[0003] Chinese patent application publication number: CN118071546A discloses a BIM-based construction process management method and system, which obtains first-sample BIM model data, then embeds building component features into the first-sample BIM model to generate building component features, integrates prior construction process knowledge vectors with these features to generate integrated feature vectors, performs decoding conversion based on the integrated feature vectors to generate a second-sample BIM model, and generates second-sample BIM model data in combination with the prior construction process knowledge vector of the first-sample BIM model, realizes reverse generation from integrated feature vectors to BIM models through decoding conversion, and finally combines the first-sample BIM model data with the second-sample BIM model data into target sample BIM model data for training a deep learning network to generate a target construction process decision model, thereby being able to output corresponding target construction process knowledge vectors for any loaded target BIM model data, thereby improving the intelligent level of construction process management.

[0004] It can be seen that the existing technology has the problem of low accuracy in real-time analysis of construction process data, which leads to low control accuracy in construction process management and causes the construction tasks to fail to be completed in time. Summary of the invention

[0005] To this end, the present invention provides an intelligent construction management system based on BIM to overcome the problem in the prior art that the real-time analysis of construction process data is low in accuracy, resulting in low control accuracy of construction process management and causing the construction tasks to be unable to be completed in time.

[0006] To achieve the above object, the present invention provides a BIM-based intelligent construction management system, comprising:

[0007] A construction data acquisition module is used to acquire construction information data and determine the execution order of construction tasks based on BIM;

[0008] a construction type determination module, which is connected to the construction data acquisition module and is used to calculate a construction type evaluation value according to the construction information data to determine the construction type, wherein the construction type includes a first construction type and a second construction type;

[0009] A construction management module, which is connected to the construction type determination module, and is used to determine a management method for construction tasks according to the construction type, wherein the management method for construction tasks includes a first management method for determining whether to change the order of task execution according to the required completion time of the task to be executed, and a second management method for determining whether to change the order of task execution according to the complexity of the task to be executed;

[0010] A construction progress evaluation module, which is connected to the construction management module and is used to calculate the degree of completion of the construction progress according to the phased construction progress to evaluate the construction situation;

[0011] An adjustment module, which is connected to the construction progress evaluation module and is used to determine the adjustment amount of the construction process parameters according to the discrete degree of unqualified stage progress in the construction progress;

[0012] The construction process parameters include a preset construction type evaluation value, a preset completion time, and a preset complexity;

[0013] The construction type evaluation value is calculated by the following formula and is set:

[0014] ;

[0015] Among them, P represents the construction type evaluation value, N0 represents the number of stage tasks divided by BIM for construction tasks, N represents the number of inspections during the construction stage, α represents the influence coefficient of the inspection frequency during the construction stage on the construction type evaluation value, and its value is set to 0.56, T represents the required completion time of the construction, T0 represents the maximum completion time of the same construction task, and β represents the influence coefficient of the required time of the construction task on the construction type evaluation value, and its value is set to 0.44;

[0016] The construction management module manages the construction task using a first management method under the condition that the construction type is a first construction type, and the construction management module manages the construction task using a second management method under the condition that the construction type is a second construction type;

[0017] The first adjustment coefficient is calculated and set by the following formula:

[0018] ;

[0019] The second adjustment coefficient is calculated and set by the following formula:

[0020] ;

[0021] The adjusted preset completion time T0' is set to T0'=K1×T0;

[0022] The adjusted preset complexity S0' is set to S0'=K1×S0;

[0023] The adjusted preset construction type evaluation value P0' is set to P0'=K2×P0;

[0024] Among them, K1 represents the first adjustment coefficient, M represents the discrete degree of unqualified stage progress in the construction progress, M0 represents the preset discrete degree, K2 represents the second adjustment coefficient, T0 represents the preset completion time, S0 represents the preset complexity, and P0 represents the preset construction type evaluation value.

[0025] Furthermore, the construction type determination module determines that the construction type is the first construction type according to the comparison result that the construction type evaluation value is greater than or equal to the preset construction type evaluation value; the construction type determination module determines that the construction type is the second construction type according to the comparison result that the construction type evaluation value is less than the preset construction type evaluation value.

[0026] Furthermore, the construction type evaluation value is calculated based on the number of construction phase inspections in the construction data and the required completion time of the construction.

[0027] Furthermore, under the condition that the construction task is determined to be managed by the first management method, the construction management module determines to change the task execution order based on a comparison result of the required completion time of the stage task to be executed being greater than the preset completion time when the completeness of the materials of the construction task to be executed is less than the preset completeness.

[0028] Furthermore, under the condition that the construction task is determined to be managed by the second management method, the construction management module determines to change the task execution order when the completeness of the materials of the construction task to be executed is less than the preset completeness according to the comparison result that the complexity of the task in the construction stage is greater than or equal to the preset complexity.

[0029] Furthermore, the preset degree of completeness is determined according to an average value of degrees of completeness of a number of materials for the task to be constructed.

[0030] Furthermore, the construction progress evaluation module determines that the construction progress is qualified based on the comparison result that the construction progress completion degree is greater than or equal to the preset completion degree, and the construction progress evaluation module determines that the construction progress is unqualified based on the comparison result that the construction progress completion degree is less than the preset completion degree.

[0031] Furthermore, under the condition that the adjustment module determines that the construction progress is unqualified, the adjustment module determines the adjustment amount of the construction process parameter according to the comparison result of the discrete degree of the unqualified stage progress in the construction progress and the preset discrete degree.

[0032] Furthermore, the preset discrete degree is determined according to an average value of the discrete degrees of unqualified construction progress of a number of identical construction tasks under the condition that the construction progress is unqualified.

[0033] Furthermore, the adjustment amount of the preset construction type evaluation value is negatively correlated with the discrete degree of unqualified stage progress, the preset completion time is positively correlated with the discrete degree of unqualified stage progress, and the preset complexity is positively correlated with the discrete degree of unqualified stage progress.

[0034] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention determines the construction type by calculating the construction type evaluation value according to the stage detection frequency and duration requirement of the construction task through the construction type determination module. If the construction type evaluation value is greater than or equal to the preset construction type evaluation value, it means that the construction type is a task type with a low stage detection frequency but a short construction task completion time requirement. If the construction type evaluation value is less than the preset construction type evaluation value, it means that the construction type is a type with a high stage detection frequency but a long construction task completion time requirement. The above method improves the accuracy of real-time analysis of construction process data and thus improves the control accuracy of construction process management.

[0035] Furthermore, the present invention determines a corresponding construction task management method according to a corresponding construction type through the construction management module. If the construction type is the first construction type, the construction management module determines that the urgency of the stage task is low when the degree of completeness of the materials of the construction task to be executed is less than a preset degree of completeness and the required completion time of the stage task to be executed is greater than the preset completion time. Therefore, the construction management module determines to change the task execution order. Through the above method, the accuracy of real-time analysis of construction process data is improved, thereby improving the control accuracy of construction process management.

[0036] Furthermore, the present invention determines a corresponding construction task management method according to a corresponding construction type through the construction management module. If the construction type is the second construction type, the construction management module determines that the completion difficulty of the stage task is high when the completeness of the materials of the construction task to be executed is less than a preset completeness and the complexity of the stage task to be executed is greater than or equal to a preset complexity. Therefore, the construction management module determines to change the task execution order. Through the above method, the accuracy of real-time analysis of construction process data is improved, thereby improving the control accuracy of construction process management to improve construction efficiency.

[0037] Further, the present invention determines whether the construction progress is qualified according to the comparison result of the completion degree of the construction progress and the preset completion degree of the construction progress through the construction progress evaluation module. Comparing the completion degree of the construction progress with the preset completion degree of the construction progress can provide real-time monitoring and evaluation of the construction progress. This enables the project management team to timely understand the construction progress, effectively track and control the progress execution, and through the comparison results, potential progress delays and problems can be discovered early. If the completion degree of the construction progress is lower than the preset completion degree of the construction progress, the possible causes of the delay can be quickly identified, and corresponding corrective measures can be taken to avoid further delays and schedule conflicts. The comparison results provide a basis for project decision-making. If the construction progress is consistent with or ahead of the preset progress, it can be confirmed that the project is proceeding as planned, and adjustments can be made on the premise of meeting quality requirements, such as resource reallocation, process optimization, etc., and if the construction progress is delayed, timely actions can be taken, such as overtime, increasing resource input or rearranging the work order, etc., to ensure that the project can be completed on time. Comparing the completion degree of the construction progress with the preset completion degree of the construction progress helps to improve the efficiency of project management. Accurate progress monitoring and evaluation can help the project management team better understand the progress of the project, adjust resource allocation in a timely manner, optimize work processes, and take appropriate measures to improve efficiency and reduce costs.

[0038] Furthermore, the present invention determines the volatility of the construction progress based on the comparison result of the discrete degree of unqualified stage progress in the construction progress and the preset discrete degree. If the volatility is large, it means that the original dependency relationship is destroyed due to the frequent change of the execution order of construction tasks in the construction stage progress, which may cause the subsequent tasks to fail to start on time, thereby delaying the entire construction progress. This situation of destroying the process dependency relationship may lead to a high discrete degree of unqualified construction progress. At this time, the first adjustment coefficient is used to increase the judgment parameter of changing the execution order of tasks to reduce the phenomenon of unqualified stage progress. If the volatility is small, it means that the discrete degree of unqualified is low because most of the construction types are misjudged as the second construction type, thereby reducing the operation of changing the execution order of tasks during the construction process. At this time, the second adjustment coefficient is used to reduce the judgment parameter of the second construction type. The above method improves the accuracy of real-time analysis of construction process data and thus improves the control accuracy of construction process management to improve construction efficiency.

[0047] The BIM-based intelligent construction management system of the embodiment of the present invention includes:

[0048] A construction data acquisition module is used to acquire construction information data and determine the execution order of construction tasks based on BIM;

[0049] a construction type determination module, which is connected to the construction data acquisition module and is used to calculate a construction type evaluation value according to the construction data to determine the construction type, wherein the construction type includes a first construction type and a second construction type;

[0050] A construction management module, which is connected to the construction type determination module, and is used to determine a management method for construction tasks according to the construction type, wherein the management method for construction tasks includes a first management method for determining whether to change the order of task execution according to the required completion time of the task to be executed, and a second management method for determining whether to change the order of task execution according to the complexity of the task to be executed;

[0051] A construction progress evaluation module, which is connected to the construction management module and is used to calculate the degree of completion of the construction progress according to the staged construction progress to evaluate the construction situation;

[0052] The adjustment module is connected to the construction progress evaluation module and is used to determine the adjustment amount of the construction process parameters according to the discrete degree of unqualified stage progress in the construction progress.

[0053] The construction information data in the embodiment of the present invention includes but is not limited to "construction time requirements, complete information of construction materials and logical relationships of construction tasks", and the construction process parameters include preset construction type evaluation values, preset completion time and preset complexity.

[0054] Specifically, the construction type determination module determines the construction type according to the comparison result between the construction type evaluation value P and the preset construction type evaluation value P0;

[0055] If P≥P0, the construction type determination module determines that the construction type is the first construction type;

[0056] If P<P0, the construction type determination module determines that the construction type is the second construction type.

[0057] Specifically, the construction type evaluation value P is calculated by the following formula:

[0058] ;

[0059] Among them, N0 represents the number of stage tasks divided into construction tasks based on BIM, N represents the number of inspections in the construction stage, α represents the influence coefficient of the inspection frequency in the construction stage on the evaluation value of the construction type, and its value is set to 0.56. T represents the required completion time of the construction, T0 represents the maximum completion time of the same construction task, and β represents the influence coefficient of the required time of the construction task on the evaluation value of the construction type, and its value is set to 0.44.

[0060] The preset construction type evaluation value in the embodiment of the present invention is a value obtained by calculating the construction type evaluation value when N=0.2N0 and T=0.8T0.

[0061] The present invention determines the construction type by calculating the construction type evaluation value of the construction type determination module according to the stage detection frequency and duration requirement of the construction task. If the construction type evaluation value is greater than or equal to the preset construction type evaluation value, it means that the construction type is a task type with a low stage detection frequency but a short construction task completion time requirement. If the construction type evaluation value is less than the preset construction type evaluation value, it means that the construction type is a type with a high stage detection frequency but a long construction task completion time requirement. The above method is used to improve the accuracy of real-time analysis of construction process data and thus improve the control accuracy of construction process management.

[0062] Specifically, the construction management module manages the construction task with a first management method under the condition that the construction type is a first construction type, and the construction management module manages the construction task with a second management method under the condition that the construction type is a second construction type.

[0063] Specifically, under the condition that the construction task is managed by the first management method, the construction management module determines whether to change the task execution order according to the comparison result of the required completion time W of the stage task to be executed and the preset completion time W0 when the completeness of the materials of the construction task to be executed is less than the preset completeness;

[0064] If W>W0, the construction management module determines the execution order of the replacement tasks;

[0065] If W≤W0, the construction management module determines not to change the task execution order;

[0066] Among them, the preset completion time W0 is the average completion time of tasks in the same construction stage, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0067] The construction task materials in the embodiment of the present invention include but are not limited to "concrete, steel and auxiliary materials". The completeness of the construction task materials is the ratio of the types of existing materials that meet the construction requirements to the types of construction task materials.

[0068] The present invention determines the corresponding construction task management method according to the corresponding construction type through the construction management module. If the construction type is the first construction type, the construction management module determines that the urgency of the stage task is low when the completeness of the materials of the construction task to be executed is less than the preset completeness and the required completion time of the stage task to be executed is greater than the preset completion time. Therefore, the construction management module determines to change the task execution order. Through the above method, the accuracy of real-time analysis of construction process data is improved, thereby improving the control accuracy of construction process management.

[0069] Specifically, under the condition that the construction task is managed by the second management method, the construction management module determines whether to change the task execution order according to the comparison result of the complexity S of the construction stage task and the preset complexity S0 when the completeness of the materials of the construction task to be executed is less than the preset completeness;

[0070] If S≥S0, the construction management module determines the execution order of the replacement tasks;

[0071] If S<S0, the construction management module determines not to change the task execution order;

[0072] Among them, the value of the preset complexity S0 is the average value of the complexity of the stage construction tasks in the construction task, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0073] When determining the execution order of replacement tasks, the construction management module in the embodiment of the present invention executes the construction tasks divided based on BIM in sequence, and the complexity of the construction phase tasks includes but is not limited to "determined according to the technical difficulty of the construction phase tasks, determined according to the number of cross-dependencies between the construction phase tasks and other construction phase tasks, and determined according to time pressure."

[0074] The present invention determines the corresponding construction task management method according to the corresponding construction type through the construction management module. If the construction type is the second construction type, the construction management module determines that the completion difficulty of the stage task is high when the completeness of the materials of the construction task to be executed is less than the preset completeness and the complexity of the stage task to be executed is greater than or equal to the preset complexity. Therefore, the construction management module determines to change the task execution order. Through the above method, the accuracy of real-time analysis of construction process data is improved, thereby improving the control accuracy of construction process management to improve construction efficiency.

[0075] Specifically, the construction progress evaluation module determines whether the construction progress is qualified according to the comparison result of the construction progress completion degree D and the preset construction progress completion degree D0;

[0076] If D≥D0, the construction progress assessment module determines that the construction progress is qualified;

[0077] If D<D0, the construction progress assessment module determines that the construction progress is unqualified;

[0078] Among them, the value range of the preset construction progress completion degree D0 is set to 0.85-1, and the value of the preset construction completion degree D0 is preferably 0.9, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0079] The degree of completion of the construction progress in the embodiment of the present invention is the ratio of the construction progress in a single cycle to the construction progress required in the cycle. The construction process is divided into 5 cycles according to the required completion time of the construction, and the degree of completion of the tasks in each cycle is determined in turn.

[0080] The present invention determines whether the construction progress is qualified according to the comparison result of the completion degree of the construction progress and the preset completion degree of the construction progress through the construction progress evaluation module. The comparison of the completion degree of the construction progress and the preset completion degree of the construction progress can provide real-time monitoring and evaluation of the construction progress. This enables the project management team to timely understand the construction progress, effectively track and control the progress execution, and through the comparison results, potential progress delays and problems can be discovered early. If the completion degree of the construction progress is lower than the preset completion degree of the construction progress, the possible causes of the delay can be quickly identified, and corresponding corrective measures can be taken to avoid further delays and construction period conflicts. The comparison results provide a basis for project decision-making. If the construction progress is consistent with or ahead of the preset progress, it can be confirmed that the project is proceeding as planned, and adjustments such as resource reallocation and process optimization can be made under the premise of meeting quality requirements. If the construction progress is delayed, timely actions can be taken, such as overtime, increasing resource input or rearranging the work order, etc., to ensure that the project can be completed on time. Comparing the completion degree of the construction progress with the preset completion degree of the construction progress is helpful to improve the efficiency of project management. Accurate progress monitoring and evaluation can help the project management team better understand the progress of the project, adjust resource allocation in a timely manner, optimize work processes, and take appropriate measures to improve efficiency and reduce costs.

[0081] Specifically, under the condition that the adjustment module determines that the construction progress is unqualified, the adjustment module determines the adjustment amount of the construction process parameter according to the comparison result of the discrete degree M of the unqualified stage progress in the construction progress and the preset discrete degree M0;

[0082] If M≥M0, the adjustment module determines to adjust the preset completeness and the preset complexity by a first adjustment coefficient;

[0083] If M<M0, the adjustment module determines to adjust the preset construction type evaluation value by a second adjustment coefficient;

[0084] Among them, the value of the preset discrete degree M0 is the average value of the discrete degrees of unqualified construction progress of several identical construction tasks under the condition of unqualified construction progress, but the above value is not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0085] Specifically, the first adjustment coefficient K1 is calculated and set by the following formula:

[0086] ;

[0087] The second adjustment coefficient K2 is calculated and set by the following formula:

[0088] ;

[0089] The adjusted preset completion time T0' is set to T0'=K1×T0;

[0090] The adjusted preset complexity level S0' is set to S0'=K1×S0.

[0091] The adjusted preset construction type evaluation value P0' is set to P0'=K2×P0;

[0092] The present invention determines the volatility of the construction progress based on the comparison result of the discrete degree of unqualified stage progress in the construction progress and the preset discrete degree. If the volatility is large, it means that the original dependency relationship is destroyed due to the frequent change of the execution order of construction tasks in the construction stage progress, which may cause the subsequent tasks to fail to start on time, thereby delaying the entire construction progress. This situation of destroying the process dependency may lead to a high discrete degree of unqualified construction progress. At this time, the judgment parameter of changing the execution order of tasks is increased by the first adjustment coefficient to reduce the phenomenon of unqualified stage progress. If the volatility is small, it means that the discrete degree of unqualified is low because most of the construction types are misjudged as the second construction type, thereby reducing the operation of changing the execution order of tasks during the construction process. At this time, the judgment parameter of the second construction type is reduced by the second adjustment coefficient. Through the above method, the accuracy of real-time analysis of construction process data is improved, thereby improving the control accuracy of construction process management to improve construction efficiency.
