Method for dynamically arranging smoke detectors in CAD drawing

Abstract

The invention belongs to the technical field of drawing analysis, and discloses a method for dynamically arranging smoke detectors in a CAD drawing. The method comprises a dynamic arrangement method and a component analysis module, and the specific operation steps of dynamically arranging smoke detectors in a CAD drawing are as follows: S1, obtaining a building base drawing dwg file to be drawn; S2, through a cad analysis service, obtaining information of floors related to the drawing and information of the most basic primitives of the components. According to the invention, a deep neural network model is utilized to solve the problem of accurate recognition of components and spaces in CAD architectural design drawings, and excessive dependence of component recognition on layers is reduced; based on the identified components and spaces, the problem of arrangement of smoke detector components in electrical design is solved; by means of accurate calculation of a computer, it can be guaranteed that placement of the components completely conforms to design specifications, and compared with manual design and manual drawing, labor cost and time cost are saved to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of drawing analysis, in particular to a method for dynamically arranging smoke detectors in a CAD drawing. Background technique [0002] CAD drawings specifically refer to drawings drawn by CAD software. These drawings are widely used in the construction industry and are the main basis for architectural reference drawings. They are widely popular due to their clear data records for detailed observation and easy adjustment. [0003] In the field of architectural design and construction, the drawing of CAD drawings is mainly done by electrical designers with many years of work experience to manually place and arrange components, but this method usually leads to the following problems in the placement of smoke detector components: The coverage radius of the smoke detector components is variable, and usually depends on the placement space. With the help of the existing drawing software, the coverage of each smok...

Problems solved by technology

[0003] In the current field of architectural design and construction, CAD drawings are mainly placed and arranged manually by electrical designers with many years of work experience. However, this method usually leads to the following problems in the placement of smoke detector components: The coverage radius of smoke detector components is variable and usually depends on the placement space. With the help of existing drawing software, it is impossible to accurately determine the coverage area of ​​each smoke detector, and some corners of the space may not be able to Covered, there may be safety hazards; in order to avoid the existence of safety hazards, ensure that the smoke detector can completely cover its monitoring area, so that redundant smoke detectors are placed in the coverage area, resulting in an increase in cost; the designer manually Arrangement, the time period is long, and it is impossible to respond quickly and timely to changes in construction; the drawing of construction drawings usually requires experienced electrical design engineers, and their accumulated industry knowledge is required as the basic condition for drawing, resulting in high manual design costs
