Description

Technical Field

[0001] The present invention relates to the technical field of digital construction, and specifically provides a data management system and method for digital construction. Background Technique

[0002] With the development of the information society, the traditional construction industry has integrated digital technologies to form digital construction solutions. Digital construction refers to the application of digital technologies in all aspects of building design, construction, supervision, management, etc. Thanks to the continuous development of digital technologies, the modern construction industry has been continuously improving in terms of digitalization. After the construction industry has transformed from past manual workshops, mold making, and manual operations to digitalization and intelligence, it has achieved development from manpower to capital, from technology to management, and from single units to combinations. The importance of digital construction lies in its ability to improve the quality and efficiency of building construction projects.

[0003] Current digital construction solutions focus on process design and process supervision, and lack research on the application scenarios of horizontally integrating data from various construction units. In actual construction scenarios, due to insufficient on-site infrastructure, it is difficult to comprehensively grasp the construction progress of all construction units, so it is difficult to coordinate the construction progress among various construction units only relying on the existing construction management system. Summary of the Invention

[0004] The purpose of the present invention is to provide a data management system and method for digital construction to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A data management method for digital construction: The method includes:

[0006] Step S100: Split the overall construction plan and mark the associated nodes and critical nodes in the overall construction plan;

[0007] Step S200: Set a management interval according to the overall construction plan and the current construction progress, and adjust the speed of construction units whose predicted time is outside the management interval;

[0008] Step S300: Calculate the reference construction progress of the associated nodes and adjust the construction progress of the construction units participating in the associated node construction;

[0009] Step S400: Obtain the construction drawings for the next stage of construction according to the adjustment of the construction progress.

[0010] Further, step S100 includes:

[0011] Step S101: Split the overall construction plan into construction sub-plans corresponding to each construction unit. The construction sub-plan includes the construction process of the corresponding construction unit, and the construction process includes construction projects. Arrange all construction projects in the order of the implementation sequence of the construction sub-plans corresponding to the construction units.

[0012] Step S102: Obtain related construction projects, and set the construction project group composed of related construction projects as an associated node.

[0013] When two different construction units need to construct simultaneously at a certain stage, or a construction project of one construction unit is a prerequisite for a construction project of another unit, such construction projects are determined to be associated projects with each other.

[0014] Step S103: Mark the key nodes in the overall construction plan. The key nodes include several construction projects, and the several construction projects correspond to several different construction units respectively. The key nodes represent the project nodes with partial or all delivery results during the implementation process or at the end of the construction projects.

[0015] The key node represents a key step completed during the project implementation process and is a checkpoint for project progress management (check point). For example: before and after the key node, the project objectives change, or there are phased delivery results when the key node is completed.

[0016] Further, step S200 includes:

[0017] Step S201: Obtain the project workload of each construction unit, and perform unit conversion on the project workload of each construction unit. One project workload of a construction unit corresponds to one unit-converted standard workload.

[0018] Normalization makes the work difficulty of each project workload unified, eliminating the interference of workloads with different difficulties on the prediction of the construction time of the construction unit.

[0019] Step S202: Set the currently under-construction key node as the current key node, obtain the implemented time t0 of the current key node, calculate the current construction speed of each construction unit and the predicted time for each construction unit to complete the current key node according to the current construction speed, calculate the average value of the predicted times for all construction units to complete the current key node, denoted as the average predicted time t pre , obtain the planned time T of the current key node from the overall construction plan plan , set the first adjustment coefficient α1 and the second adjustment coefficient α2, and calculate the first reference time T1 for the expected completion of the current key node, where T1 = t0 + (α1 × t pre+α2×t plan ), satisfying the condition: α1 + α2 = 1, where t plan = T plan - t0;

[0020] Step S203: Set the management interval, and the management interval is the progress interval [t min , t max , where t min is the minimum value of t plan and T1, and t max is the maximum value of t plan and T1. When the predicted time for the construction unit to complete the current key node is outside the progress interval, adjust the construction speed of the construction unit to obtain the first construction speed of the corresponding construction unit. When the predicted time for the construction unit to complete the current key node is within the progress interval, the value of the first construction speed of the corresponding construction unit is the current construction speed v0 of the corresponding construction unit, and v0 = Q0 / t0, where Q0 is the total standard workload of the corresponding construction unit that has completed the current key node within t0 time.

[0021] The progress interval is used to evaluate the progress of the current project. The overall construction progress of each construction unit and the planned construction progress are used as the basis for evaluating the progress of the current project at the same time, taking into account both the original construction plan and the impact of the actual situation on the construction progress;

[0022] Further, Step S203 includes:

[0023] Step S11: Obtain the unit time length t * , where t * = (t max - t min ) / 2, and set the unit adjustment time length t δ ;

[0024] Step S12: Calculate the first adjustment time t 1 adj of the corresponding construction unit. When t x > t max , t 1 adj = t x - ((t x - t max ) / t * ) × t δ . When t x < t min , t 1 adj = t x + ((t min - t x ) / t* ) × t δ , where t x represents the predicted time for the xth construction unit to complete the current critical node;

[0025] Step S13: Calculate the first construction speed v of the corresponding construction unit 1 c , v 1 c = (Q - Q0) / t 1 adj , where Q is the total standard workload for the corresponding construction unit to complete the current critical node.

[0026] Further, step S300 includes:

[0027] Step S301: Obtain the associated nodes that are not completed during the process of completing the current critical node. Among them, the associated node node ass corresponds to several construction units. Among them, the construction process of completing the associated node node ass is subordinate to the construction process of completing the current critical node;

[0028] Step S302: Set the predicted time or the first adjustment time for the construction unit to complete the current critical node as the second predicted time, calculate the absolute value of the difference between the second predicted time of the several construction units and the midpoint of the progress interval, and take the construction unit corresponding to the minimum value of the absolute value of the difference between the second predicted time and the midpoint of the progress interval as the reference construction unit;

[0029] Selecting the construction unit corresponding to the minimum value of the absolute value of the difference between the second predicted time and the midpoint of the progress interval as the reference construction unit is to select a construction unit with a moderate construction speed as the reference unit, and the construction speed of the reference unit is more in line with the actual situation of the construction;

[0030] Step S303: Calculate the second reference time T2 for the reference construction unit to complete the associated node, and calculate the predicted time for the remaining construction units except the reference construction unit among the several construction units to complete the associated node;

[0031] Step S304: Set the third adjustment coefficient β1 and the fourth adjustment coefficient β2, and calculate the second adjustment time t of each of the remaining construction units except the reference construction unit 2 adj , when t y < T2, t 2 adj = t y + β1 × (T2 - t y ), when t y > T2, t 2adj = t y -β2×(t y - T2),t y represents the predicted time for a certain construction unit to complete the associated node among the remaining construction units excluding the reference construction unit, t 2 adj , representing the second adjustment time corresponding to the said certain construction unit;

[0032] Step S305: Calculate the second construction speed v for the remaining workload of the current critical node to be completed according to the adjustment time corresponding to the construction unit 2 c , where v 2 c = (Q - Q0) / t 2 adj .

[0033] Furthermore, step S400 includes:

[0034] Step S401: Obtain the correspondence between the workload of the construction project and the construction drawings of the project;

[0035] Step S402: Set the planned time T for the next stage of construction, p calculate the current planned workload Q corresponding to each construction unit 0 p and the adjusted planned workload Q adj p , where, Q 0 p = v0 × T p , Q adj p = v 2 c × T p ;

[0036] Step S403: Calculate the construction drawings corresponding to the maximum extractable workload Qn of each construction unit, where Q n is the maximum value among Q corresponding to each construction unit 0 p and Q adj p , and distinguish and mark the construction drawings corresponding to Q n on the construction drawings corresponding to Q 0 p and the construction drawings corresponding to Q adj p .

[0037] Q 0 pIndicates the construction tasks corresponding to the next stage for the construction unit according to the existing construction speed, Q adj p Indicates the construction tasks in the downward stage for the construction unit after adjustment, and marks the two situations differently to prompt the construction unit to slow down or speed up the construction progress.

[0038] To better implement the above method, a data management system is also proposed. The system includes:

[0039] A construction plan management module, a first adjustment module, a second adjustment module, and a construction plan distribution module. Among them, the construction plan management module is used to split and mark the construction plan, the first adjustment module is used to adjust the construction progress outside the management interval, the second adjustment module is used to adjust the construction progress of the construction units participating in the associated section construction, and the construction plan distribution module is used to obtain the construction drawings for the next stage of construction according to the adjustment of the construction progress.

[0040] Furthermore, the first adjustment module includes a key node acquisition unit, a current construction speed calculation unit, a key node predicted time calculation unit, a first reference time calculation unit, an interval management unit, and a construction speed adjustment unit. Among them, the key node acquisition unit is used to acquire key nodes, the current construction speed calculation unit is used to calculate the current construction speed, the key node predicted time calculation unit is used to calculate the predicted time of key nodes, the first reference time calculation unit is used to calculate the first reference time, the interval management unit is used to judge whether the predicted time to complete the current key node is within the management interval, and the construction speed adjustment unit is used to calculate the first construction speed for the construction progress of the construction unit that needs to be adjusted.

[0041] Furthermore, the second adjustment module includes an associated node acquisition unit, a reference construction unit acquisition unit, an associated node time calculation unit, and a second adjustment time calculation unit. Among them, the associated node acquisition unit is used to acquire associated nodes, the reference construction unit acquisition unit is used to acquire reference construction units, the associated node time calculation unit is used to calculate the predicted time to complete the associated nodes, and the second adjustment time calculation unit is used to calculate the second adjustment time for each of the remaining construction units except the reference construction unit.

[0049] Please refer to Figure 1 、 Figure 2 and Figure 3 , the present invention provides the following technical solutions:

[0050] Step S100: Split the overall construction plan and mark the associated nodes and key nodes in the overall construction plan;

[0051] Among them, step S100 includes:

[0052] Step S101: Split the overall construction plan into construction sub-plans corresponding to each construction unit. The construction sub-plans include the construction processes corresponding to the construction units, and the construction processes include construction projects. Arrange the construction projects in the order of implementation of the construction sub-plans corresponding to the construction units.

[0053] Step S102: Obtain relevant construction projects, and set the group of construction projects composed of relevant construction projects as an associated node;

[0054] Step S103: Mark the key nodes in the overall construction plan. The key nodes include several construction projects, and the several construction projects respectively correspond to several different construction units one by one. The key nodes represent the project nodes with partial or all delivery results during the implementation or at the end of the construction project;

[0055] As Figure 3 shown, A, B, C, and D respectively represent four different construction units. In an overall construction plan, the construction sub-plan of Construction Unit A includes a1 → a2 → a3 → a4, where a1, a2, a3, and a4 respectively represent the 1st, 2nd, 3rd, and 4th construction projects, and a1, a2, a3, and a4 respectively correspond to the unitized workloads of qa1, qa2, qa3, and qa4. According to the same corresponding relationship, the construction sub-plan of Construction Unit B includes b1 → b2 → b3, and b1, b2, and b3 respectively correspond to the unitized workloads of qb1, qb2, and qb3. The construction sub-plan of Construction Unit C includes c1 → c2 → c3 → c4, and c1, c2, c3, and c4 respectively correspond to the unitized workloads of qc1, qc2, qc3, and qc4. The construction sub-plan of Construction Unit D includes d1 → d2 → d3 → d4, and d1, d2, d3, and d4 respectively correspond to the unitized workloads of qd1, qd2, qd3, and qd4. The combination of c3 and d3 is marked as an associated node, and the combination of a4, b3, c4, and d4 is marked as a key node.

[0056] Step S200: Set the management interval according to the overall construction plan and the current construction progress, and adjust the speed of the construction units whose predicted time is outside the management interval;

[0057] Among them, Step S200 includes:

[0058] Step S201: Obtain the project workload of each construction unit, perform unitization processing on the respective project workloads of the construction units, and one project workload of a construction unit corresponds to a unitized standard workload;

[0059] During the implementation process, the workload can be evaluated by evaluating the labor consumption and material consumption of the construction, or by establishing a BIM system to obtain the evaluation data of the construction volume;

[0060] One example of unitization: a1, a2, a3, and a4 respectively correspond to the unitized workloads of pa1, pa2, pa3, and pa4, and set the maximum value among pa1, pa2, pa3, and pa4 as pa max, the minimum value is set to pa min , the normalized workload of the i-th construction project of Construction Unit A is qai = (((pai - pa min ) / pa max - pa min ) + k) × f, where k represents the unit coefficient, f represents the scaling ratio, k is to prevent 0 from appearing in the item (pai - pa min ) from affecting the calculation result, and f is to control the interval of the overall data calculation.

[0061] Step S202: Set the currently under-construction key node as the current key node, obtain the implemented time t0 of the current key node, calculate the current construction speed of each construction unit and the predicted time for each construction unit to complete the current key node according to the current construction speed, calculate the average value of the predicted times for all construction units to complete the current key node, and denote it as the average predicted time t pre , obtain the planned time T of the current key node from the overall construction plan plan , set the first adjustment coefficient α1 and the second adjustment coefficient α2, and calculate the first reference time T1 for predicting the completion of the current key node, where T1 = t0 + (α1 × t pre + α2 × t plan ), satisfying the condition: α1 + α2 = 1, where t plan = T plan - t0;

[0062] After t0 time, Construction Unit A completes a1 and a2, Construction Unit B completes b1, Construction Unit C completes c1 and c2, and Construction Unit D completes d1 and d2. Among them, the current construction speed of Construction Unit A is v a cur = (qa1 + qa2) / t0, and the predicted time for Construction Unit A to complete the current key node is t a pre = (qa3 + qa4) / v a cur , calculate the predicted time for Construction Unit B to complete the current key node as t b pre according to the same calculation method, the predicted time for Construction Unit C to complete the current key node is t c pre and the predicted time for Construction Unit D to complete the current key node is t d pre , and the average predicted time t pre = (t a pre + t b pre + t cpre +t d pre ) / 4;

[0063] Step S203: Set the management interval, and the management interval is the progress interval [t min , t max , where t min is the minimum value of t plan and T1, and t max is the maximum value of t plan and T1. When the predicted time for the construction unit to complete the current key node is outside the progress interval, adjust the construction speed of the construction unit to obtain the first construction speed of the corresponding construction unit. When the predicted time for the construction unit to complete the current key node is within the progress interval, the value of the first construction speed of the corresponding construction unit is the current construction speed v0 of the corresponding construction unit, and v0 = Q0 / t0, where Q0 is the total standard workload of the corresponding construction unit that has completed the current key node within the time t0;

[0064] For example, T plan - t0 = 5, t pre = 4, then t max = 5, t min = 4, t * = 0.5. The predicted time for Construction Unit B to complete the current key node is 6, and the first adjustment time t b1 adj = t b pre + 2t δ , and the first construction speed v b1 c = (qb2 + qb3) / t b1 adj ;

[0065] Among them, Step S203 includes:

[0066] Step S11: Obtain the unit time length t * , where t * = (t max - t min ) / 2, and set the unit adjustment time length t δ ;

[0067] Step S12: Calculate the first adjustment time t 1 adj of the corresponding construction unit. When t x > t max , then t 1 adj = t x - ((tx -t max ) / t * ) × t δ , when t x < t min time, t 1 adj = t x + ((t min - t x ) / t * ) × t δ , where t x represents the predicted time for the xth construction unit to complete the current key node;

[0068] Step S13: Calculate the first construction speed v of the corresponding construction unit 1 c , v 1 c = (Q - Q0) / t 1 adj , where Q is the total standard workload for the corresponding construction unit to complete the current key node.

Among them, the associated node node ass corresponds to a number of construction units. Among them, the construction process of completing the associated node node ass is subordinate to the construction process of completing the current key node;

[0072] Step S302: Set the predicted time or the first adjustment time for the construction unit to complete the current key node as the second predicted time, calculate the absolute value of the difference between the second predicted time of the several construction units and the midpoint of the progress interval, and take the construction unit corresponding to the minimum absolute value of the difference between the second predicted time and the midpoint of the progress interval as the reference construction unit;

[0073] Step S303: Calculate the second reference time T2 for the reference construction unit to complete the associated node, and calculate the predicted time for the remaining construction units except the reference construction unit among the several construction units to complete the associated node;

[0074] Step S304: Set the third adjustment coefficient β1 and the fourth adjustment coefficient β2, and calculate the second adjustment time t of each of the remaining construction units except the reference construction unit 2 adj , when ty <At time T2, t 2 adj = t y + β1×(T2 - t y ), when t y >T2, t 2 adj = t y - β2×(t y - T2), t y represents the predicted time for a certain construction unit among the remaining construction units excluding the reference construction unit to complete the associated node, t 2 adj , represents the second adjustment time corresponding to the said certain construction unit;

[0075] Step S305: Calculate the second construction speed v for the remaining workload of the current critical node to be completed according to the adjustment time corresponding to the construction unit 2 c , where v 2 c = (Q - Q0) / t 2 adj .

[0076] For example, t c pre = 4.75, t d pre = 4, the midpoint of the progress interval [t min , t max is 4.5, Construction Unit C is used as the reference construction unit, T2 = qc3 / v c cur , Construction Unit D corresponds to the second adjustment time t d2 adj = t d re + β1×(T2 - t d2 adj ), the second construction speed corresponding to Construction Unit C is v d2 c = (qd3 + qd4) / t d2 adj .
