[0002] Nowadays, the mechanical and electrical systems of buildings are becoming more and more complex. During construction, water supply and drainage, electrical, ventilation and other professional pipelines are crisscrossed. Traditional pipeline comprehensive design relies on manual comparison of two-dimensional drawings, which is not only inefficient and error-prone, but also common for pipeline collisions at the construction site, resulting in delays in the construction period and a surge in costs. It is also difficult to ensure efficiency during construction, and problems that are prone to occur during specific construction cannot be effectively avoided according to different construction environments; it is also difficult to respond quickly to design changes, and subsequent operation and maintenance are also difficult due to incomplete information and unreasonable spatial layout. Although BIM technology has been applied, it lacks the assistance of deep intelligent algorithms, fails to fully tap the value of data, and is difficult to achieve all-round and dynamic pipeline planning and control.

[0010] Calculate the maximum equivalent stress and deformation of the pipeline system: Under load condition j, first number the existing longitudinal seismic supports and lateral seismic supports in the finite element analysis model as 1, 2, ..., n, respectively. Then delete one of the i-th constraint supports in the model, load the model according to the seismic load in step (3), and obtain the maximum equivalent stress σij and maximum deformation δij of the pipeline system after removing the constraint support i. Repeat the above operation to finally obtain the corresponding n maximum equivalent stress values ​​and n maximum deformation values ​​after removing the 1, 2, ..., n-th constraint supports separately. The model component sections are classified into three types: point, rectangular section and circular section. The normal line of the section edge is drawn and converted into a positioning line. If the positioning lines of different components intersect, it is determined that there is a collision between the components. This collision information is passed to the collector, and then the collision check results are output through a list and displayed in the form of a table. The table contains the ID, type and axis network position information of the collision component. The use of secondary development plug-ins to optimize and adjust the model means: using plug-ins can quickly move, align, offset, bend up and down, and other quick operations on the pipeline model components of electromechanical equipment. Compared with the "break-connect-set height-stretch-set height-connect" operation in the original software, it greatly reduces the time for optimization and adjustment and improves efficiency. The various calculation results obtained are analyzed by analyzing the relevant parameter indicators such as the number of bends, the number of remaining collisions, the number of pipes, the length of the pipeline, and the concentration of bends to form a calculation result analysis system, which comprehensively evaluates the advantages and disadvantages of the calculation results for user reference. The calculation results obtained are matched with the information of each component in the original model through the secondary development of the modeling software, and the calculation results are generated into the BIM model of the corresponding modeling software. In a building space of a type of building, it is necessary to list all the electromechanical systems and subsystems in the area, and prioritize all the systems. The priority ranking is combined with the order of small pipes giving way to large pipes, pressure giving way to non-pressure, and general giving way to special rules in the electromechanical deepening design rules, which can be sorted in multiple ways. The deepening design parameters of each system include the minimum spacing of pipelines, pipeline bending height, pipeline bending merging distance, pipeline bending type, pipeline bending angle, pipeline bending width, and pipeline bending height. The detection point cloud composed of detection data points is obtained by AI and the original point cloud is obtained by scanner acquisition; the ISS algorithm is used to extract feature data points from the original point cloud and the detection point cloud respectively, and the feature data points in the detection point cloud are matched with the feature data points in the original point cloud. The matching number and matching mean of the feature data points in the detection point cloud are collected and associated and integrated for effectiveness evaluation and analysis. Avoid possible problems during the construction process and avoid unexpected situations that may occur during construction, which may lead to relatively high construction costs.
