Examples
The embodiment provides an adjacency relation identification method, which comprises the following steps:
and extracting the boundary information of the space according to the building space model, and storing the boundary information as space boundary data consisting of a plurality of straight line segments. The boundary of the space is formed by a plurality of line segments in a closed surrounding manner;
and extracting the boundary information of the wall according to the building space model, and storing the boundary information as wall boundary data consisting of a plurality of straight line segments. The boundary of the wall body is formed by a plurality of line segments in a closed surrounding manner;
if the boundary of a certain space is superposed with the boundary of a certain wall, the space and the wall have an adjacent relation;
if a common adjacent wall body exists between one space and the other space, determining the coincident line segments of the boundary of the two spaces and the corresponding common adjacent wall body respectively;
lines perpendicular to the corresponding common adjacent wall bodies are respectively made through two end points of the overlapped line segments and are enclosed to form a rectangular area; and
if the rectangular areas of the two spaces are separated or circumscribed, the two spaces are not adjacent to each other. If the rectangular areas of the two spaces are crossed, the two spaces are adjacent to each other.
Specifically, as shown in fig. 1, the layout of the space and the wall is determined according to the building space model, and boundary data of the space and the wall is obtained.
Wherein the boundary of the elevator hoistway (i.e. the wall adjacent to the elevator hoistway) comprises: wall 1, wall 2, wall 3 and wall 4. The boundary of the electric well (i.e. the wall adjacent to the electric well) comprises: wall 2, wall 5, wall 4 and wall 3. Then, the elevator shaft and the electric well have common adjacent walls "wall 3", "wall 2" and "wall 4".
As shown in fig. 2, for a common adjacent wall "wall 2": lines perpendicular to the wall body 2 are respectively made through two end points of a superposed line segment C of the elevator shaft and the wall body 2 and form a rectangular area C in an enclosing mode; lines perpendicular to the wall body 2 are respectively made through two end points of the superposed line segment D of the electric well and the wall body 2 and form a rectangular area D in an enclosing mode. The rectangular area C and the rectangular area D are not crossed, and the two spaces, namely the elevator shaft and the electric shaft, cannot be judged to be adjacent through the wall body 2.
As shown in fig. 3, for a common adjacent wall "wall 4": lines perpendicular to the wall 4 are respectively made through two end points of a superposed line segment E of the elevator shaft and the wall 4 and form a rectangular area E in an enclosing mode; lines perpendicular to the wall body 4 are respectively made through two end points of a superposed line segment F of the electric well and the wall body 4 and form a rectangular area F in an enclosing mode. The rectangular area E and the rectangular area F do not intersect, and the two spaces, namely the elevator shaft and the electric shaft, cannot be judged to be adjacent to each other through the wall 4.
As shown in fig. 4, for a common adjacent wall "wall 3": lines perpendicular to the wall body 3 are respectively made through two end points of a superposed line segment a of the elevator shaft and the wall body 3 and form a rectangular area A in an enclosing mode; lines perpendicular to the wall body 3 are respectively made through two end points of the superposed line segment B of the electric well and the wall body 3 and form a rectangular area B in an enclosing mode. The rectangular area A and the rectangular area B are crossed, so that the elevator shaft and the electric shaft are adjacent to each other.
As long as two spaces can be judged to be closely adjacent through a wall body, the two spaces have close-proximity relation. It should be noted that if only one side of the rectangular regions of the two spaces is overlapped, there is no intersection of the inner regions, and the adjacent relationship is not true.
By the method, the building space model can be automatically inspected quickly, information of the building space model can be mastered more quickly, inspection burden of manual inspection is reduced, error rate in the inspection process is reduced, and positive significance is brought to improvement of inspection efficiency and inspection quality. In addition, the method can also effectively avoid the misjudgment of the adjacent relation.
In the present embodiment, the building space model includes a building Bim model of ifc.
The boundary of the space is the inner edge of the wall. Therefore, if the boundary of the space and the boundary of the wall body are overlapped, the space and the wall body can be judged to have adjacent relation. Considering the precision problem of floating point number of computer, the coordinates of the boundary may be different from those of the boundary of 14016.95 and 14017, for example, and cannot be completely consistent, thereby affecting the coincidence judgment. Therefore, before calculation, the start-stop coordinates of the line segments need to be advanced to be compatible in accuracy, such as +/-1.
Geometrical information of space and wall: can be obtained by taking out Body in IfcProductDefinitionshape of IfcSpace, that is IfcExtrudedAreaSolid spatial stretched Body information, which contains different types of stretched bodies, including IfcArbitraryClosedProfileDef (complex closed contour type), IfcRectangleProfileDef (rectangular contour type). IfcArbitraryClosedProfileDef includes IfcIndexedPolyCurve (polygonal closed curve), Ifcpolyline (broken line). And extracting boundary information of the space and the wall according to different types and storage formats, and storing the boundary information into boundary data consisting of a plurality of straight line segments.

As the engaging head 710 continues to extend into the engaging cavity 610, the engaging head 710 pushes the first rotating member 620 to rotate in the direction a shown in fig. 8, and the end of the first connecting head 600 simultaneously pushes the second rotating member 720 to rotate in the direction b shown in fig. 8. In this process, the first rotating member 620 rotates against the elastic force of the first elastic member 640, and the second rotating member 720 rotates against the elastic force of the second elastic member 740.
As the engaging head 710 continues to extend into the engaging cavity 610, the first rotating member 620 rotates to completely enter the first receiving groove 611, and the second rotating member 720 rotates to completely enter the second receiving groove 711, as shown in fig. 9.
As the matching head 710 continues to extend into the matching cavity 610, the first rotating member 620 and the second rotating member 720 are in contact, when the first rotating member 620 and the second rotating member 720 are completely attached, the end faces of the first rotating member 620 and the second rotating member 720 are aligned and combined to form a complete cylindrical structure, the central axes of the cylinders corresponding to the first rotating member 620 and the second rotating member 720 are overlapped, the central axes of the rotating shafts of the first rotating member 620 and the second rotating member 720 are overlapped, and at this time, under the action of the elastic force of the first elastic member 640 and the second elastic member 740, the first rotating member 620 and the second rotating member 720 can be rotated and reset together. In this way, the first rotating member 620 partially rotates into the second receiving groove 711, the second rotating member 720 partially rotates into the first receiving groove 611, and the mating head 710 cannot be disengaged from the mating cavity 610, so as to lock the first connector 600 and the second connector 700, as shown in fig. 10. Meanwhile, the first conductive contact 612 is attached to the second conductive contact 712 to achieve electrical conduction.

The auxiliary lever 900 is rotatably installed to the low frequency storage area 220 along a circumferential direction of the auxiliary lever 900. The auxiliary bar 900 is slidably installed to the low frequency storage area 220 in the axial direction of the auxiliary bar 900.
The auxiliary rod 900 has the moving rods 910 disposed along the radial direction thereof, the moving rods 910 are distributed along the axial direction thereof in a linear array, and the moving rods 910 are disposed corresponding to the first extension rod 630.
The auxiliary lever 900 has a first operating state, a second operating state, and a third operating state. When the auxiliary lever 900 is in the first working state, the toggle lever 910 is separated from the toggle portion 631. When the auxiliary lever 900 is in the second working state, the toggle lever 910 rotates to engage with the toggle portion 631. When the auxiliary lever 900 is in the third operating state, the auxiliary lever 900 moves axially to push the first extension lever 630 by the shifting lever 910, so that the first rotating member 620 and the second rotating member 720 rotate back to the state shown in fig. 9, and the first rotating member 620 and the second rotating member 720 are unlocked from the first connector 600 and the second connector 700, so that the connection can be disconnected again by driving the second connector 700 away from the first connector 600.
The auxiliary lever 900 may be driven to move in the axial direction by a lead screw mechanism, and the rotation of the auxiliary lever 900 may be achieved by a rotation mechanism, but is not limited thereto.
