Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drawing review, in particular to a safety exit design review method and system based on architectural drawings. BACKGROUND

[0002] In recent years, artificial intelligence and big data technologies have been widely applied in various fields, and artificial intelligence drawing review has begun to enter the construction drawing review industry. With the rapid development of science and technology, people have new requirements for residential conditions, and the quality problems of the construction industry have become increasingly prominent.

[0003] The essence of the quality problem of the building is the design problem of the construction drawing, so the drawing review is a very important link. Intelligent drawing review intelligently judges whether the drawing conforms to the specification through algorithm, and uses computer intelligent identification to find drawing defects more quickly and accurately, to assist drawing reviewers to reduce the omission rate, improve the review efficiency and reduce the review cost. Therefore, developing an AI intelligent drawing review system to replace manual work to realize automatic drawing review has become an inevitable trend of the digital development of the architectural design industry.

[0004] At present, the architectural design industry commonly uses CAD software to draw drawings, and the drawings drawn by hand need to rely on experienced engineers or special auditors to judge whether the design of the drawings violates the national building standards, which makes the drawing review work different due to the individual project experience, knowledge reserve and working years, and a large amount of manpower also makes it impossible to establish a perfect process for the audit work. Secondly, the drawings are divided into five major specialties of architecture, structure, water supply and drainage, heating and ventilation, and electricity, which cannot be reviewed individually. If the engineers of different specialties follow the three-school two-audit work process, it is easy to cause the drawing review time to be too long, and even affect the building life cycle. At the same time, the audit unit will also be affected by too many audit projects, and the relevant personnel will have a tight audit work time and a heavy task, which will often lead to the neglect of data audit and the reasonable design of the scheme.

Specifically:

[0066] ① For residential buildings with a height of 10 floors or less, when the building area of any floor of the residential unit is greater than 650m 2 , or the distance from the door of any suite to the safety exit is greater than 15m, the safety exits of each floor of the residential unit shall not be less than 2.

[0071] Semantic explanation:

[0072] Safety exit: a common door connected to the stairwell space, and the other side of the common door leads to a space with an area greater than 3m 2 .

[0073] Building area: find the text "building area of this floor" in the non-side column description area, expand the text bbox to the right by 3000, and the obtained text is the building area of this floor. If the text "building area of this floor" cannot be found, calculate the total area of the space in the frame.

[0074] Distance: The straight-line distance between the midpoints of the bboxes on the two door components.

[0075] Intersection over Union (IOU): The area of ​​a component that overlaps with the space / the area of ​​the component (the original design drawings used graphics to determine the direction of the door opening, but now the IOU is used to make it easier for the computer to identify).

[0080] S103. If the number of safety exits is greater than or equal to 2, then obtain and determine whether the distance between two adjacent safety exits is greater than or equal to 5m.

[0081] S104. If the distance between all two adjacent safety exits is greater than or equal to 5m, then determine whether there is a first-level or first-level text in the drawing frame based on the drawing frame.

[0082] S105. If the text for "1st floor" or "first floor" does not exist in the drawing frame, then obtain the stairwell door.

[0083] S106. Calculate and determine whether the overlap between the stairwell door and the stairwell is greater than or equal to 0.9;

[0084] S107. If the overlap between the stairwell door and the stairwell is greater than or equal to 0.9, then determine whether there is a door in the stairwell vestibule that is connected to the corridor space or hallway space.

[0085] S108. If there is a vestibule door connected to the corridor space or hallway space, calculate the overlap between the vestibule door and the stairwell vestibule.

[0086] S109. Based on the calculation results, determine whether the overlap between the vestibule door and the stairwell vestibule is greater than or equal to 0.9;
