Description

Technical Field

[0001] The present invention relates to the technical field of pipeline layout optimization, and in particular to a pipeline optimization design auxiliary platform based on BIM technology. Background Art

[0002] Building Information Modeling is a new tool in architecture, engineering and civil engineering. It is used to describe computer-aided design that is mainly based on three-dimensional graphics, object-oriented, and related to architecture. Since it realizes the visualization of building models from monotonous two-dimensional drawings to three-dimensional space, this technology can be used to intuitively realize the modular construction of building models in computers, which is very suitable for pipeline optimization design.

[0003] At present, the existing electromechanical BIM model lacks the calculation and optimization basis for the resistance along the pipeline when in use, resulting in the appearance of large-angle elbows in some areas with ample space, which leads to increased resistance or aggravated noise and vibration in the pipe. It has a weak guiding role in the specific location setting of the pipeline diameter change, which not only increases the material cost in construction, but also increases the energy waste during the operation of the system; and the existing BIM technology still relies on human experience and operation, and does not achieve autonomous learning. It can only identify collision points, but cannot identify areas that do not meet the specifications. In terms of pipeline modeling, it is impossible to perform point-to-point autonomous in-depth design and fault judgment according to preset information parameters and restriction requirements. In particular, the modeling of some areas does not meet the requirements of national mandatory provisions due to design neglect, and the rework and modification caused after subsequent construction will be very troublesome, and some even cannot be modified. In view of this, the present invention proposes a pipeline optimization design auxiliary platform based on BIM technology. Summary of the invention

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 6The present invention proposes a pipeline optimization design auxiliary platform based on BIM technology, including a preprocessing module, a BIM modeling module, a collision detection module, a simulation module, a collaborative design module and a feedback module. The preprocessing module is used to collect all data related to pipeline design, including design drawings, topography, and existing pipeline network distribution parameters, such as pipeline burial depth, location coordinates, equipment specifications, etc. in underground pipeline networks. At the same time, the data is preprocessed, such as deduplication, format unification, classified storage, etc., to provide an accurate and complete data foundation for subsequent modeling, analysis and optimization; the BIM modeling module uses BIM software to establish a three-dimensional model of the pipeline based on the preprocessed data. The model should include building structure, pipeline system, equipment, etc. The three-dimensional model can intuitively display the layout and status of the pipeline system, providing visual support for subsequent analysis and optimization; the collision detection module uses the collision detection function of the BIM software to perform collision detection on the pipeline model and identify the collisions between pipelines and between pipelines and buildings. The conflict points between structures are detected, and the pipeline layout is optimized and adjusted according to the detection results to reduce errors and rework during construction and improve construction efficiency and quality; the simulation module conducts in-depth analysis of the data of the pipeline system, such as flow analysis, pressure analysis, temperature analysis, etc. At the same time, the simulation function of the BIM software is used to simulate the operation process of the pipeline system to predict possible problems and failures, provide a scientific basis for the design and operation of the pipeline system, improve the reliability and economy of the system, and enable various professional designers to design and modify on a unified platform to ensure the consistency and coordination of the design. The collaborative design module shares BIM modeling data through the BIM modeling module to realize real-time transmission and feedback of information, ensure the smooth implementation of the design plan and facilitate subsequent maintenance and management.

[0050] The present invention performs collision detection through the established three-dimensional model of the pipeline, identifies the conflict points between pipelines and between pipelines and building structures, and optimizes and adjusts the pipeline layout based on the detection results, reserving sufficient maintenance space. At the same time, the simulation function of BIM software is used to simulate the operation process of the pipeline system, predict possible problems and failures, and solve possible problems in advance.

[0051] Furthermore, the simulation module includes a cost calculation optimization unit, a resistance optimization unit and a space restriction optimization unit. The cost calculation optimization unit is used to calculate the final cost of each provided data cost. The resistance optimization unit is used to calculate the final resistance of the system through the determined pipeline model direction. The space restriction optimization unit is used to obtain the optimal construction plan through preference priorities and mandatory conditions.

[0052] Among them, the existing BIM can input cost parameters in advance, and after pricing each section of material, determine the price of the system pipeline, and mark the system that exceeds the price with a color block. At the same time, combined with the automatic path setting, it can predict whether the use of a certain material exceeds the cost and the approximate range of the overpricing.

[0053] In the present invention, the simulation module can autonomously learn through a large number of models, and then combine the specifications, owner preferences and the results of autonomous learning to conduct autonomous in-depth design of the pipeline from a certain point to another end point. At the same time, the resistance coefficients of different elbows, tees and accessories can be combined to obtain the preliminary system resistance. For example, for the air duct on the 50th floor of a standard civil building, the present invention can realize the automatic generation of the air duct system from a certain position in the northeast corner of the core tube to a certain position in the southwest corner, and automatically calculate the along-the-way resistance of the section, the wind speed of each air outlet, the cost and other information, providing a basis for subsequent optimization and adjustment.

[0055] S01. Establish the BIM model of the building's mechanical and electrical integrated pipelines and perform collision checks to ensure that the basic information of the model is correct.

[0060] S023. Use the checking algorithms and tools in the model platform to automatically check the BIM model according to the set emphasis parameters and logical relationships, and form an error summary report;

[0061] S024. According to the error summary report, optimize and adjust the BIM model accordingly to resolve the identified error information;

[0062] In the BIM modeling module, enter the emphasized parameters to establish a logical relationship, such as: the distance between the two sides of the fire damper and the wall is no more than 200mm; where the rule name is: fire damper installation rule; condition: the distance between the walls on both sides of the fire damper object; expression: D1<=200AND D2<=200 (D1 is the distance from the left side of the fire damper to the nearest wall, and D2 is the distance from the right side of the fire damper to the nearest wall);

[0063] Among them, after the collision check phase of step S02, each color block is used to display information that does not meet the specifications or whether it violates the mandatory provisions of the specifications for reference in subsequent adjustments. In the design stage, if the mandatory provisions are violated, the platform can warn and the design information cannot be edited. If the general provisions are violated, the system only warns and uses color blocks to indicate the inconsistent information content.

[0064] S03, preference priority input, waiting for intelligent model generation;

[0065] Among them, the preference priority input includes the priority input of the comprehensive pipeline layout (for example, sprinkler pipes or drainage pipes are preferably laid close to the beams and the minimum distance to the beams is provided; the drainage ditch is kept 200mm away from the unit as much as possible, and at least 50mm away from the unit if conditions restrict it; flange connection is given priority to for pipeline connection, and clamp connection is set for locations with insufficient flange space, etc.) and adjustment with preference factors (for example, after setting the distance to 400mm, multiple schemes are automatically compared, and a parameter information table is provided for the final resistance along the pipeline system after optimization, the space required for the ceiling, the minimum maintenance space for various components that need maintenance, the local minimum distance, etc.) for the designer to confirm and select.

[0066] S04, along the resistance adjustment, through the plate properties, automatically set elbows, various tees and valves in the above steps, the system pipe resistance can be preliminarily calculated, and the maximum resistance point and the optimizable point are displayed with color blocks, so as to provide the best solution that the builder or designer wants;

[0067] S05. Adding power equipment module: by basically determining the direction of the pipeline model, the final resistance of the system is calculated, and suitable power equipment is recommended. At the same time, a suitable power equipment module is added at the end of the pipeline system in the platform;

[0068] By accurately calculating the resistance along the pipeline, we can prevent large-angle elbows from appearing in areas with ample space, reduce the resistance of the pipeline system, reduce material costs during construction, and prevent energy waste during the operation of the pipeline system.

[0069] S06a. Automatic acquisition of reducers and elbow components and their types: By providing preset parameters (including but not limited to the composition of system components, resistance coefficient of pipeline materials, pipeline shape and size, preliminary preset reducers, etc.), inputting the recommended wind speed of each air outlet, and combining with the computational fluid dynamics module, the platform automatically obtains the optimal pipeline reducer or elbow solution.
