Description
Technical Field
The invention relates to the technical field of BIM (building information modeling), in particular to a method and a device for arranging an air duct based on BIM technology and a readable medium.
Background
In recent years, intelligent design is a new thinking in the building industry. With the eastern wind of BIM development, there are many software companies, design enterprises, which are devoted to but focus more on the building plan push generation of simple projects, but the electromechanical aspects are less involved.
In practice, however, for various reasons, the electromechanics profession is not very much "smart designed", but is instead at risk of decreasing efficiency. The wind system is the most commonly related content in the design of heating ventilation air conditioner, and is characterized in that: 1. large scale and wide range. Almost all of the items are related to the item, taking up more time for the designer. 2. Relatively simple repetition. The arrangement of the wind pipelines can be performed in a modularized manner, and a certain amount of simple repeated workload exists. 3. The modularization logic is relatively simple, and based on the wind speed control method, the size of the wind pipe can be defined according to the relatively simple regularity of the number of wind openings with fixed wind quantity.
Fig. 1 shows a design flow of a current wind system, and the current wind pipe design drawing method based on BIM has the following disadvantages: 1. the repeated workload is large, and after the air duct information and the air port information (air duct route, air port size and the like) are planned, the air port number, the connection sequence and the like still need to be calculated according to an air velocity method, so that the connecting pieces are arranged, the air ports are drawn, and the workload is large. Especially in the BIM context, the operability of BIM software is more cumbersome than that of CAD software, and the workload of the part is amplified. 2. Against design underlying logic: the design flow is generally from shallow to deep, and in the flow shown in fig. 1, a heating and ventilation designer usually adopts an auxiliary line to outline the pipeline route first and then converts the pipeline route into a double-line air pipe, namely, the process from a sketch, a scheme to a construction drawing is designed; in BIM design, necessary parameters are required to be input for drawing any entity, such as pipe diameter, elevation and the like of a pipeline are required to be input from the beginning, so that the problem of parameter modification after entity selection exists, and modeling difficulty and modification workload are brought to designers. 3. Lack of tools for single-wire routing conversion to model entities: as described above, the design process summary needs to outline the planned route by using a single line, and then models the air duct system according to the planned route in the later period, and the whole process is manually modeled by a designer, so that the design efficiency is greatly affected.
