Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent bridge construction, and particularly relates to a digital twin incremental launching visualization control method and system based on Building Information Modeling (BIM). Background Art

[0002] With the development of BIM (Building Information Modeling) technology, its application in the incremental launching construction of bridges is becoming increasingly important, bringing unprecedented accuracy and efficiency to the entire construction process. By creating a detailed three-dimensional model, BIM technology enables the construction team to rehearse the entire incremental launching process in a virtual environment, thereby identifying and resolving potential design conflicts, structural problems, and construction obstacles. This forward-looking planning not only helps reduce on-site changes and delays but also significantly enhances construction safety.

[0003] In the prior art, Chinese Patent (Application No.: 202410469538.0) discloses a method and system for visualizing the progress of the incremental launching of a steel truss girder based on digital twin. This patent only obtains the monitoring data of the incremental launching displacement of the steel truss girder in real time through any one or more of the devices and instruments such as Beidou positioning technology, intelligent video image recognition, total station robot, and millimeter wave radar. However, in the actual incremental launching operation process, the incremental launching displacement depends on the walking machine for incremental launching construction, and this patent does not obtain the lateral, longitudinal, and vertical horizontal displacements through the walking machine control cabinet equipment, resulting in insufficient accuracy. In addition, during the simulation progress display process of this patent, the progress is visually displayed by the visibility and invisibility of BIM components. However, the actual on-site incremental launching process is a dynamic movement process, and this patent does not combine the BIM model for real-time dynamic movement display, failing to fully utilize the BIM three-dimensional visualization effect, so there are certain limitations. Summary of the Invention

[0004] To solve the deficiencies of the prior art and achieve the purpose of real-time dynamic visualization of the incremental launching of a steel truss girder and improving visualization accuracy, the present invention adopts the following technical solutions: A digital twin incremental launching visualization control system based on Building Information Modeling includes a data acquisition module, a modeling module, and an incremental launching control module; The data acquisition module is connected to the walking machine total control cabinet equipment, and the collected data includes the incremental launching displacement data of the walking machine; The modeling module constructs an incremental launching model based on Building Information Modeling (BIM) in a three-dimensional environment based on the incremental launching scenario and the collected data, and associates the collected data with the incremental launching model; The incremental launching construction module drives the Building Information Modeling to simulate the on-site incremental launching operation according to the displacement data of the data acquisition module, thereby realizing digital twin.

[0005] Furthermore, the data acquisition module is connected to the walking machine through the main control cabinet equipment of the walking machine and each sub-control cabinet equipment, so as to collect the jacking displacement data for driving the steel truss girder to move through the displacement data of the steel truss girder connected to the walking machine; the jacking model includes a main pier with a pier-side bracket, a splicing platform and a temporary pier are sequentially arranged on one side of the main pier, and a steel guide girder is arranged on the pier-side bracket, the splicing platform and the temporary pier, and the steel guide girder is used to guide the displacement of the steel truss girder.

[0006] Furthermore, the data acquisition module includes obtaining on-site data automatically in real time and obtaining on-site data by means of manual reporting.

[0007] Furthermore, the jacking model is jointly constructed based on the Geographic Information System (GIS) and the Building Information Model.

[0008] Furthermore, the jacking construction module supports playing back the data of the jacked rounds and importing the data of the subsequent jacking rounds, and then deducing the complete process of the subsequent jacking in advance on the Building Information Model. Among them, in the process of deducing on the Building Information Model, the calculation rule of the moving speed in the jacking process is displacement divided by time, where both displacement and time can be configured; the Building Information Model simulation includes lateral, longitudinal and vertical displacement data to simulate the vertical jacking of the steel truss girder by the walking machine.

[0009] Furthermore, the system further includes an early warning module connected to the data acquisition module, which is used to compare the on-site collected data with a preset range, and when the collected data exceeds the preset range, an early warning signal is sent.

[0010] Furthermore, the system further includes a data analysis module connected to the data acquisition module, which analyzes the state during the jacking construction process according to the collected operation data; other monitoring data is also collected, including three categories of environmental monitoring data, response monitoring data and change monitoring data. Among them, the environmental monitoring data includes the bridge site environmental temperature, the steel truss girder component temperature and video data; the response monitoring data includes the deflection of the guide girder, the stress of the member, the forward displacement of the pier, the stress of the pier, the strain of the pier, the height difference of the steel truss girder, the lateral displacement of the steel truss girder, the jacking pressure, the jacking pressure, the internal force of the member, the stress of the member; the change monitoring data includes the settlement of the pier, the settlement of the splicing platform, the elevation of the front end of the guide girder and the displacement of the front end of the guide girder; the monitoring and acquisition method is carried out by any one or more of a temperature sensor, a total station, a level, a strain sensor, a camera; thus ensuring the safety of bridge construction.

[0011] The digital twin jacking visualization control method based on the Building Information Model performs visualization control of jacking according to the digital twin jacking visualization control system based on the Building Information Model, and includes the following steps: Step 1: Build a top-up model, and establish and publish a building information model based on the construction drawings and construction environment; Step 2: Setting the pushing rounds, associating each pushing round with the steel truss beam and the steel guide beam of the building information model, and setting the component identification (e.g., color) of the model for visual display of the model; Step 3: Setting the pushing task: Based on the pushing rounds, detailed configuration is performed for each round; Step 4: Obtain on-site jacking displacement data and map it to the corresponding jacking round according to the start and end time. The jacking round is associated with the jacking model based on step 2 to drive the jacking model to control the current jacking progress in real time.

[0012] Furthermore, in step 1, the building information model is provided with a main pier of a pier side bracket, a splicing platform and a temporary pier are sequentially provided on one side of the main pier, and a steel guide beam is provided on the pier side bracket, the splicing platform and the temporary pier, and the steel guide beam is used to guide the displacement of the steel truss beam; In the step 2, each jacking round is associated with the steel truss beam and the steel guide beam of the building information model respectively, the first round is associated with the steel guide beam and the steel truss beam, and the second round and subsequent rounds are associated with other steel trusses respectively; The detailed configuration in step 3 includes whether to assemble, whether to push, whether to install or remove the steel guide beam, the start time, and the end time, wherein each round is configured in the order of assembling first and then pushing, and the last round, in addition to assembly and pushing, also needs to configure and remove the steel guide beam; In step 4, the on-site jacking displacement data is acquired by a data acquisition module installed in the main control cabinet of the crawler, through each sub-control cabinet, by the displacement data of the steel truss connected to the crawler, to acquire the jacking displacement data that drives the steel truss to move.

[0013] Furthermore, the driving jacking model in step 4 controls the current jacking speed in real time, which specifically includes the following steps: Step 4.1, the established building information model of the steel truss beam and the steel guide beam is initially published outside the two ends of the outermost pier so as to be subsequently moved according to the received displacement; Step 4.2, before the steel truss beam is pushed forward, all the building information models of the steel truss beam and the steel guide beam are hidden, and only the building information models of the temporary pier, the main pier, the bracket beside the pier and the splicing platform are displayed; Step 4.3, the position movement display of the steel truss beam is dynamically displayed through the task rounds configured in step 3. If the task type is assembly, the building information model is displayed in a display and hidden manner. If the task type is pushing, the steel truss beam is pushed to move according to the acquired on-site displacement data. The specific steps include the following: Step 4.3.1: For the models mounted in the first round, assemble them first. By displaying them, convert the steel guide beams and steel trusses hidden in step 4.2 from hidden state to displayed state. The method of converting from hidden to displayed is to call the transparency and display method of the 3D engine interface, so as to more realistically display the on-site assembly process. Step 4.3.2: For the models mounted in the first round, jacking is performed after assembly. The jacking operation is performed by assembling the preparatory process of jacking construction simulated by the assembly in step 4.3.1. The position of the displayed steel truss is driven to move in real time according to the displacement data obtained from the on-site crawler control cabinet. The moving speed is calculated using the displacement data, start time and end time of the crawler. The formula is as follows: displacement data / (end time-start time); Step 4.3.3: For the model mounted in the second round, repeat the assembly process in step 4.3.1 and the pushing process in step 4.3.2, so as to push the steel trusses mounted in the second round forward for a certain distance; the assembly and pushing of the steel trusses in other rounds are the same; Step 4.3.4, the last round, the steel guide beam needs to be removed. According to whether the steel beam is removed in step 3, the steel guide beam is changed from the display state to the hidden state, thereby realizing the removal of the steel guide beam.

[0014] The advantages and beneficial effects of the present invention are: Based on the existing technology that only has component visibility, the present invention uses two actions, namely assembly visibility and visibility and jacking movement, and the displacement data of the BIM simulation jacking process is obtained through the crawler main control cabinet. The data is more accurate and reasonable, and the obtained displacement data drives the BIM model to move and update in real time, thereby realizing the interconnection between on-site jacking construction and BIM model, and then truly simulates the on-site jacking construction process based on BIM, truly realizing the automatic update of the jacking visualization IM model.

[0027] The following further elaborates on the detailed implementation manners of the present invention in conjunction with the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0028] As Figure 1 shown, the digital twin incremental launching visualization control system based on the building information model includes a data acquisition module, a modeling module, an incremental launching control module, an early warning module, and a data analysis module.

[0029] The data acquisition module is installed inside the main control cabinet of the walking machine, and is used to collect the incremental launching displacement data of the walking machine. The main control cabinet is connected to the sub-control cabinets, each sub-control cabinet is respectively connected to the walking machine, and the walking machine is further connected to the steel truss girder 1, and then drives the steel truss girder 1 to move through the incremental launching displacement. In addition to automatically obtaining on-site data in real time, the data acquisition module also supports data collection through on-site manual reporting.

[0030] The modeling module is data-associated with the data acquisition module, and mainly establishes a GIS+BIM model in a three-dimensional environment, including scene schematic models such as the steel truss girder 1, temporary piers 2, splicing platforms 3, steel guide girders 6, pier-side brackets 5, and main piers 4.

[0031] The jacking construction module is connected to the modeling module. Based on the BIM model and according to the displacement data of the data acquisition module, it pushes the BIM model to simulate the on-site jacking operation, thus realizing digital twin. In addition to receiving the data of the acquisition module in real time, pushing the BIM model, and then simulating the on-site jacking construction process, it also supports playing back the data of the jacked rounds; and importing the data of subsequent jacking rounds, and then pre-playing the complete process of subsequent jacking in advance on the BIM model. During the BIM deduction process, the calculation rule for the model movement speed during jacking is displacement divided by time, where both displacement and time can be configured. The BIM model not only simulates the lateral and longitudinal displacement data of the lateral jack 7 and longitudinal jack 8 of the gantry crane, but also simulates the vertical displacement of the vertical jack 9 of the gantry crane, and then simulates the effect of the vertical jacking of the steel truss girder 1 by the gantry crane, such as Figure 2 shown.

[0032] The warning module is connected to the data acquisition module and is used to compare the values collected from the on-site data with the preset range. When the collected data exceeds the preset range, the warning module will send a warning signal.

[0033] The data analysis module is connected to the data acquisition module and analyzes the status during the jacking construction process based on the operation data of the data acquisition module; it also collects other monitoring data, and the monitoring types include three categories: environmental monitoring data, response monitoring data, and change monitoring data. Among them, the environmental monitoring data includes the bridge site environmental temperature, the temperature of the steel truss girder components, and video data; the response monitoring data includes the deflection of the guide girder, the stress of the members, the longitudinal displacement of the piers, the stress of the piers, the strain of the piers, the height difference of the steel truss girder, the lateral displacement of the steel truss girder, the jacking pressure, the lifting pressure, the internal force of the members, and the stress of the members; the change monitoring data includes the settlement of the piers, the settlement of the splicing platform, the elevation of the front end of the guide girder, and the displacement of the front end of the guide girder; the monitoring and acquisition methods use any one or more of temperature sensors, total stations, level gauges, strain sensors, and cameras for monitoring; thus ensuring the safety of bridge construction.

[0034] As Figure 3 shown, the digital twin jacking visualization control method based on the building information model includes the following steps: Step 1, construct the jacking model. As Figure 4 shown, according to the construction drawings and the surrounding environment, establish a BIM model, which includes a steel truss girder 1, temporary piers 2, splicing platforms 3, steel guide girders 6, pier side brackets 5, and main piers 4, and publish the model; Step 2, set the jacking rounds. Associate each jacking round with the steel truss girder 1 and the steel guide girder 6 of the BIM model established in Step 1 respectively, and set the color of the model for convenient visualization display on the model. Among them, the first round is associated with the models of the steel guide girder 6 and the steel truss girder 1. For the second round and subsequent rounds, other steel truss girder 1 models are associated respectively; Step 3, setting the pushing task, based on the pushing rounds in step 2, detailed configuration is performed for each round, including whether to assemble or push, whether to remove the steel guide beam 6, start time, and end time. Each round is configured in the order of assembly first and then pushing. In addition to assembly and pushing, the last round also requires configuration to remove the steel guide beam 6.

[0035] Step 4: Obtain the on-site jacking displacement data and map it to the corresponding jacking round according to the start time and end time. The jacking round is associated with the model according to step 2, so as to drive the model to display the current construction progress in real time. Driving the model to display the current construction progress in real time specifically includes the following steps: Step 4.1: Initialize and publish the BIM models of the steel truss beam 1 and the steel guide beam 6 outside the two ends of the outermost piers so that they can be moved later according to the received displacements. Figure 4 As shown; Step 4.2: Before the steel truss beam is pushed forward, the BIM models of the steel truss beam 1 and the steel guide beam 6 are all hidden, and only the BIM models of the temporary pier 2, the main pier 4, the pier side bracket 5 and the splicing platform 3 are displayed, as shown in the figure below. Figure 5 As shown; Step 4.3, the position movement display of the steel truss 1 is dynamically displayed through the task rounds configured in step 3. Specifically, if the task type is assembly, the model is displayed in a display and hidden manner. If the task type is top pushing, the model will be pushed to move according to the acquired on-site displacement data; specifically, the following steps are included: Step 4.3.1: For the models mounted in the first round, assemble them first. By displaying them, convert the hidden steel guide beam 6 and steel truss beam 1 in step 4.2 from hidden state to displayed state. The method of converting hidden state to displayed state can be achieved by calling the transparency and display method of the 3D engine interface, so as to more realistically display the on-site assembly process. Figure 6 , Figure 7 As shown; Step 4.3.2: For the models mounted in the first round, push-up is performed. Through the assembly in step 4.3.1, the preparatory process of push-up construction has been simulated. The next step is the push-up operation. According to the displacement data transmitted by the on-site crawler control cabinet, the displayed model position is driven to move in real time. The moving speed is mainly based on the displacement data, start time and end time transmitted by the crawler. The speed of pushing the BIM model is calculated in real time as: displacement data / (end time-start time). Figure 7 , Figure 8 As shown; Step 4.3.3: For the model connected in the second round, repeat the assembly process in Step 4.3.1 and the jacking process in Step 4.3.2 to jack the steel truss girder 1 connected in the second round forward by a certain distance, as Figure 9 , Figure 10 shown; the assembly and jacking of the steel truss girder 1 in other rounds are the same; Step 4.3.4: In the last round, the steel guide beam 6 needs to be removed. Then, according to the switch for removing the steel beam configured in Step 3, change the steel guide beam 6 from the displayed state to the hidden state to achieve the removal of the steel guide beam 6, as Figure 11 , Figure 12 shown.

[0036] Based on the prior art where only components can be shown or hidden, the present invention conducts visual control through two actions: assembly showing / hiding and jacking movement. Moreover, the displacement data for simulating the jacking process by BIM is obtained through the walking machine control cabinet, making the data more accurate and reasonable. Thus, the on-site jacking construction and the BIM model are interconnected, and the on-site jacking construction process is truly simulated.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
