Description

Technical Field

[0001] This invention relates to the field of architectural design and construction technology, and in particular to a method, apparatus, equipment and storage medium for automatic layout of sprinkler points. Background Technology

[0002] CAD construction drawings are created using AutoCAD software to depict the overall layout of an engineering project, including the building's external shape, internal arrangement, structural details, interior and exterior finishes, materials, equipment, and construction methods. In architectural electrical construction drawings, the floor plan typically provides a macroscopic description of the building's location and main structure, downplaying walls, doors, windows, beams, and columns, while highlighting electrical wiring. Other pipelines, such as plumbing and gas lines, are not shown on the electrical construction drawings.

[0003] An architectural floor plan, also known simply as a floor plan, is a drawing that uses a horizontal projection method and corresponding symbols to depict the walls, doors, windows, stairs, floors, and internal functional layout of a newly constructed building or structure. It reflects the building's plan shape, size, and arrangement; the location, dimensions, and materials of walls and columns; and the type and location of doors and windows.

[0004] A fire sprinkler system is a widely used fixed fire-fighting facility characterized by its low cost and high extinguishing efficiency. Depending on its function, it can be divided into two types: manual control and automatic control. Systems equipped with alarm devices can automatically sound an alarm when a fire occurs. Automatically controlled fire sprinkler systems can automatically spray and work in conjunction with other fire-fighting facilities, thus effectively controlling and extinguishing initial fires.

[0005] In architectural design drawings, fire sprinklers need to be arranged on the building floor plan. For safety and reliability, the basic principle of arrangement is that the spray coverage of the fire sprinklers should cover the entire interior space of the building. The basic principles for arranging sprinkler points are as follows:

[0006] (1) Distance between the nozzle and the adjacent wall: 300mm~1700mm

[0007] When multiple nozzles are arranged in rows, the spacing between adjacent nozzles is 1800mm to 3400mm.

[0008] (2) The current principle for the arrangement of sprinklers based on beam height is as follows: when the beam height is less than 700mm, the influence of beam height on sprinklers is ignored; when the beam height is greater than 700mm, the horizontal distance between the sprinkler and the beam satisfies the following:

[0009]

[0010] The sprinklers on both sides of the beam should meet the minimum distance from the sprinkler head to the beam edge, and the sprinklers on both sides of the beam should meet the spacing requirements in Article 1. When the sprinklers on both sides of the beam cannot simultaneously meet the requirements in the table and Article 1, sprinklers should be added at the bottom of the beam, and the distance between the sprinkler head and the beam edge should be controlled according to the distance requirements between the sprinkler head and the wall.

[0011] (3) When the nozzles are arranged in a single row, the nozzle spacing is 3000mm.

[0012] (4) When the distance between the beam and the wall is very small, the distance between the beam and the wall cannot be met at the same time. In this case, one or a row of beams can be arranged in the middle of the beam and the wall.

[0013] (5) Aesthetic requirements for spray point locations.

[0014] (6) The horizontal and vertical directions are parallel to the building outline.

[0015] (7) The nozzles are evenly distributed in the same space.

[0016] (8) The distance between the nozzles, the distance to the wall, and the distance to the beam are all integers, i.e., the units digit is 0.

[0017] (9) The spacing between positions with the same spacing is consistent, and the number is the smallest.

[0018] Currently, the method for arranging sprinklers in CAD drawings of building floor plans involves designers manually drawing the sprinkler positions according to building construction specifications. This method is time-consuming, labor-intensive, and not very accurate.

[0019] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0044] When dmin < R < dmax, F q = F G , there is no force between the particles

[0045] When R > dmin, F q < F G , the particles attract each other

The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0064] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the automatic layout of sprinkler points and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0065] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and an automatic sprinkler point layout program.

[0066] exist Figure 1 In the automatic sprinkler point layout device shown, the network interface 1004 is mainly used for data communication with the data multi-terminal synchronous processing device; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the automatic sprinkler point layout device of the present invention can be set in the automatic sprinkler point layout device, and the automatic sprinkler point layout device calls the automatic sprinkler point layout program stored in the memory 1005 through the processor 1001 and executes the automatic sprinkler point layout method provided in the embodiment of the present invention.

[0067] Based on the above hardware structure, an embodiment of the automatic sprinkler point layout method of the present invention is proposed.

[0068] Reference Figure 2 , Figure 2 This is a schematic diagram of the automatic sprinkler point layout method of the present invention. The automatic sprinkler point layout method includes the following steps:

[0069] S10. Based on the wall beam arrangement constraint, the two coordinate axes of the coordinate system of the building plan where the sprinklers need to be arranged are rasterized to obtain the raster model.

[0070] S20. Based on the rasterization model, select valid grid points through point placement logic;

[0071] S30. Adjust the position of the legal grid points using a physical simulation method, and use the adjusted position as the nozzle position.

[0072] This embodiment first establishes a rasterized model of the entire building plan requiring sprinkler placement, then selects valid grid points through point layout logic, and finally adjusts the point positions to meet the requirements using physical simulation. This solves the problem of current placement methods, which require designers to manually draw and arrange sprinkler positions according to building construction specifications, resulting in time-consuming, labor-intensive, and inaccurate methods.

[0073] In one embodiment, step S20 includes the following steps:

[0074] The intersection of the two coordinate axes is set as the pre-placement point;

[0075] Hard constraint logic checks are performed based on the pre-placed points, and the pre-placed points that satisfy the constraints are retained as the legal grid points.

[0076] It should be noted that retaining the pre-placed points that meet the constraints means meeting the distance requirements from the wall and beam.

[0077] In one embodiment, the method further includes:

[0078] The valid grid points are processed so that the building plan is fully covered.

[0079] In one embodiment, step S30 includes the following steps:

[0080] Set a physical model and model parameters, wherein the physical model is used to calculate the forces between nozzle particles and other particles, the other particles including nozzle-to-nozzle, nozzle-to-beam nearest point, and nozzle-to-wall nearest point;

[0081] By simulating the changes in the model parameters, the position of the nozzle particle when it is at rest at the equilibrium point is determined as the position of the nozzle.

[0082] Specifically, the model parameters include nozzle mass: m1, nozzle charge: q1, charge at the beam-wall representative point: q2, mass at the beam-wall representative point: m2, simulated gravitational constant: G, simulated Coulomb constant: K, damping coefficient: C, actual nozzle spacing: R, and legal nozzle spacing: [l smin ,l smax The minimum distance at which the spray system is unaffected by the beam: [l]bmin , l bmax , the minimum distance between the nozzle and the wall: [l wmin , l wmax , the position update interval: t*.

[0083] In one embodiment, in the physical model, the gravitational force between any two of the particles is

[0084] The repulsive force between any two of the particles:

[0085] The particle motion damping: F C = -V × C;

[0086] If the resultant force received by the particle is: F = F G + F q + F c ;

[0087] Then the velocity of the particle at this time is V' = V + F / m × t*;

[0088] Then the position at the next moment X′ = X + V' × t*;

[0089] Where, t* is the position update interval, K is the simulated Coulomb constant, C is the damping coefficient, R is the actual distance between the nozzles, G is the simulated universal gravitational constant, m is the weight representation of particle 1, M is the weight representation of another particle, V is the initial velocity of the particle, and V' is the updated velocity.

[0090] In one embodiment, the method further includes:

[0091] Setting different simulated Coulomb constants for different distance ranges of the particles, such that the following conditions are satisfied:

[0092] When R < dmin, F q > F G , the particles repel each other

[0093] When dmin < R < dmax, F q = F G , there is no force between the particles

[0094] When R > dmin, F q < F G , the particles attract each other

[0095] Where, the legal distance between the particles is [dmin, dmax].

[0096] It should be noted that in the physical model, the beams and walls are fixed. The model only calculates the forces between nozzle particles and other particles (nozzle-to-nozzle, nozzle-to-beam closest point, nozzle-to-wall closest point). Assuming the repulsive force is positive, the above forces, velocities, and positions are all vectors. As long as the parameters are set reasonably, the particles will eventually come to rest at the equilibrium point as time increases. The positions of each particle at this time are the optimal arrangement.

[0097] This embodiment establishes a rasterized model of the entire building floor plan requiring sprinkler installation, selects valid grid points through point placement logic, and finally adjusts the point positions using physical simulation to meet requirements. This approach comprehensively considers sprinkler layout specifications and meets neatness requirements, making the automatic placement of sprinkler points on CAD drawings reasonable and effective, significantly reducing manpower and time costs. Actual effect diagrams of several test examples are shown below. Figures 4 to 6 As shown, the sprinkler points are neatly arranged and evenly distributed in the space, meeting the requirements of the building construction plan, and the computer calculation time is relatively short (when performing tasks such as...). Figure 5 The large-scale sprinkler layout shown (e.g., 1000*1000) requires only 400ms and can also meet the requirements for inclined arrangement. Figure 6 The locations are reasonable and effective, and the efficiency of point placement is significantly improved compared to conventional manual point placement.

[0098] In addition, refer to Figure 3 This invention also proposes an automatic sprinkler point layout device, the device comprising:

[0099] Rasterization module 10 is used to rasterize the two coordinate axes of the coordinate system of the building plan where the sprinklers need to be arranged, based on the wall beam rowing constraint, to obtain a rasterized model.

[0100] Selection module 20 is used to select legal grid points based on the rasterization model through point layout logic;

[0101] The position adjustment module 30 is used to adjust the position of the legal grid points through physical simulation methods, and use the adjusted position as the nozzle position.

[0102] It should be noted that this embodiment establishes a rasterized model of the entire building floor plan that requires sprinkler layout, then selects legal grid points through point layout logic, and finally adjusts the position of the points to meet the requirements through physical simulation. This can comprehensively consider the sprinkler layout specifications and meet the requirements of neatness, making the automatic layout of sprinkler points on CAD drawings reasonable and effective, and can significantly reduce the cost of manpower and time.

[0103] In one embodiment, the selection module 20 includes:

[0104] A setting unit is used to set the intersection of the two coordinate axes as a pre-placement point;

[0105] The valid grid point selection unit is used to perform hard constraint logic checks based on the pre-placed points and retain the pre-placed points that satisfy the constraints as valid grid points.

[0106] In one embodiment, the position adjustment module 30 includes:

[0107] The parameter setting unit is used to set the physical model and model parameters. The physical model is used to calculate the force between nozzle particles and other particles. The other particles include nozzle-to-nozzle, nozzle-to-beam nearest point, and nozzle-to-wall nearest point.

[0108] The simulation unit is used to determine the position of the nozzle when the nozzle particles are at rest at the equilibrium point by simulating the changes in the model parameters.

[0109] Specifically, the model parameters include nozzle mass: m1, nozzle charge: q1, charge at the beam-wall representative point: q2, mass at the beam-wall representative point: m2, simulated gravitational constant: G, simulated Coulomb constant: K, damping coefficient: C, actual nozzle spacing: R, and legal nozzle spacing: [l smin ,l smax The minimum distance at which the spray system is unaffected by the beam: [l] bmin ,l bmax Minimum distance between the nozzle and the wall: [l] wmin ,l wmax ], Position update interval: t*.

[0110] In one embodiment, in the physical model, the gravitational force between any two particles is

[0111] Repulsive force between any two of the aforementioned particles:

[0112] The particle motion damping: F C = -V×C;

[0113] If the net force on the particle is: F = F G +F q +F c ;

[0114] The particle's velocity at this moment is V' = V + F / m × t*;

[0115] Then the position at the next moment X′=X+V'×t*;

[0116] Where t* is the position update interval, K is the simulated Coulomb constant, C is the damping coefficient, R is the actual spacing of the nozzles, G is the simulated gravitational constant, m represents the weight of particle 1, M represents the weight of another particle, V is the initial velocity of the particle, and V’ is the updated velocity.

[0117] In one embodiment, the device further includes:

[0118] A simulated Coulomb constant setting module for setting different simulated Coulomb constants for different distance ranges of the particles, such that the following conditions are satisfied:

[0119] When R < dmin, F q > F G , the particles repel each other

[0120] When dmin < R < dmax, F q = F G , there is no force between the particles

[0121] When R > dmin, F q < F G , the particles attract each other

[0122] Where the legal spacing of the particles is [dmin, dmax].

[0123] It should be noted that in the physical model, the beam and wall are fixed. Only the forces between the nozzle particles and other particles (nozzle to nozzle, nozzle to the nearest point of the beam, nozzle to the nearest point of the wall) are calculated in the model. Assuming the repulsive force direction is the positive direction, the above forces, velocities, and positions are all vectors. As long as the parameters are set reasonably, as time increases, the particles will eventually stop at the equilibrium point, and the positions where each particle is located at this time are the optimal arrangements.
