[0013] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0014] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in this disclosure, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0015] For ease of understanding, the specific process of the embodiments of this disclosure is described below. Please refer to [link / reference]. Figure 1One embodiment of the method for generating a water spray flow distribution map in this disclosure includes: Step S10: Obtain first model data of the target area, second model data of potential obstructions, and first position information and nozzle attribute parameters of at least one target nozzle; wherein, the nozzle attribute parameters include the original trajectory equation, which is used to indicate the relationship between the water jet trajectory of the corresponding target nozzle and any position in space. In the field of fire protection design of buildings, relevant regulations stipulate that automatic sprinkler systems should be installed for specific buildings or places within buildings. Automatic sprinkler systems are usually composed of components such as sprinkler heads, alarm valve assemblies, water flow alarm devices (water flow indicators or pressure switches), as well as pipes, water supply facilities, etc., and are automatic fire extinguishing systems that can spray water in the event of a fire.

[0016] The embodiments disclosed herein can be applied to the above-mentioned automatic sprinkler system. The target area can be an area in a building equipped with the above-mentioned automatic sprinkler system, or an area within a building equipped with the above-mentioned automatic sprinkler system. The target sprinkler head can be any sprinkler head in the above-mentioned automatic sprinkler system, and no specific limitation is made here.

[0017] As an example and not a limitation, the building equipped with an automatic sprinkler system (hereinafter referred to as the "target building") can be simulated in the form of a 3D model. The target area can be any area in the target building, and the target sprinkler head can be a sprinkler head within the elevation range of the target area. For example, the target area can be the floor slab of any floor in the target building, and the target sprinkler head can be a sprinkler head within the elevation range of that floor slab. No specific limitation is made here.

[0018] Specifically, in one implementation, if the target area is the floor slab of any floor in the target building, then sprinkler heads within the range from the floor slab elevation of the target area to the floor elevation of the target area are matched according to the floor elevation of the target area, to determine at least one target sprinkler head. Similarly, potential obstructions can also be matched according to the target sprinkler head matching method, the details of which will not be elaborated here.

[0019] Potential obstructions can be any object that might obstruct the water spray from the target sprinkler head; that is, any object that might alter the trajectory of the water spray from the target sprinkler head. Potential obstructions can be specified or selected via the terminal, or they can be matched based on the location of the target area and the target sprinkler head. Specific limitations are not specified here. For example, potential obstructions can be components such as walls, beams, columns, and pipelines within the target building. If the target area is the floor slab of any floor in the target building, then objects partially or entirely within the floor slab elevation range of the target area up to the floor level of the target area can be identified as potential obstructions. Specific limitations are not specified here.

[0020] The first model data can be used to indicate the shape and structure of the target area, the location of the target area within the target building, and the position of the target area relative to any reference object. Similarly, the second model data can be used to indicate the shape of potential occlusions, the location of potential occlusions within the target building, and the position of potential occlusions relative to any reference object. Both the first and second model data are three-dimensional model data and serve as virtual representations of entities.

[0021] The first location information can be used to indicate the position of each of the at least one target nozzles in the target building, or to indicate the position of each of the at least one target nozzles relative to any reference object, or to indicate the position of each of the at least one target nozzles relative to the target area, and is not specifically limited here.

[0022] Sprinkler attribute parameters are used to indicate the inherent properties of each target sprinkler, such as the type of target sprinkler, the coverage area / radius of the water spray, the original trajectory equation, the sprinkler flow rate formula, etc. The water spray attribute parameters can be specified by the user or customized, or they can be obtained from the parameters of the sprinkler manufacturer. The specifics are not limited here.

[0023] The original trajectory equation is one of the nozzle attribute parameters corresponding to each target nozzle. It is used to indicate the relationship between the water spray trajectory of the corresponding target nozzle and any position in space. The aforementioned any position in space can be the water landing point. The original trajectory equation can be a water spray trajectory equation under ideal conditions. It can be customized, obtained from presets according to the type of target nozzle, or obtained from the parameters of the sprinkler manufacturer, etc. The specifics are not limited here.

[0024] As an example, and not a limitation, the original trajectory equation for a target nozzle could be as follows:

[0025] Where h is the vertical distance between the center of the target nozzle and the water landing point, x is the horizontal distance between any point in space and the center of the target nozzle, y is the vertical distance between any point in space and the center of the target nozzle, and d is the horizontal distance between the water landing point and the center of the target nozzle. The water landing point can be any point on the horizontal plane of the target area, and there is no specific limitation here.

[0026] It should be noted that the above-mentioned original trajectory equation applies to sprinkler heads that spray water in all directions, such as upright, pendant, and ceiling-mounted sprinkler heads. The water spray trajectory of a sprinkler head that sprays water in all directions approximates a parabola, and its spray trajectory can be simulated using the original trajectory equation. Water spray trajectories with shapes other than parabolic can be simulated using other original trajectory equations, which will not be elaborated here.

[0027] like Figure 2 The image shown is a visual representation of the original trajectory equation described above. Figure 2 In this context, the center of the nozzle is the origin of the coordinate system. Figure 2 The diagram shown is a schematic representation of the curve of the original trace equation after rotating 90° clockwise; the specific details are not limited here.

[0028] The original trajectory equations described above can also be used to indicate the water spray trajectory of the corresponding target nozzle at a specified water landing point, where h and d represent the positions of the aforementioned specified landing points, which are not specifically limited here.

[0029] Step S20: Based on the first model data, the second model data, the first location information and the nozzle attribute parameters, perform collision detection on the water spray trajectory of each target nozzle and potential obstructions to determine the reachable water spray location and the reachable water spray volume of the target area. In this embodiment, the water spray trajectory of each target nozzle can be simulated by the original trajectory equation, and then the water spray trajectory of each target nozzle is compared with potential obstructions for collision detection to determine the reachable water spray position and the reachable water spray volume of the target area. At the same time, the unreachable water spray position of the target area can also be determined.

[0030] The reachable location of the water spray is the location within the target area that the water spray trajectory can cover without colliding with potential obstructions. Collision detection can determine the location within the target area that does not collide with potential obstructions. Then, based on the water spray coverage range of the target nozzle, the reachable location of the water spray can be determined.

[0031] After determining the reachable locations of the spray nozzles in the target area, the reachable water volume at each location can be determined based on the corresponding reachable nozzles. Specifically, the reachable water volume can be determined based on the number or flow rate of the reachable nozzles. For example, if the number of reachable nozzles at location A is 3 and the total number of target nozzles is 10, then the reachable water volume at location A can be 3 or 3 / 10; the specific determination is not limited here.

[0032] A water-reachable nozzle is a nozzle that can spray water to at least one target location. The same water-reachable location may be sprayed by one or more target nozzles. Therefore, the at least one target nozzle corresponding to each water-reachable location is called a water-reachable nozzle.

[0033] Step S30: Generate a water flow distribution map of the target area based on the reachable locations of water spraying in the target area and the reachable water volume at those locations.

[0034] A water flow distribution map is used to visually display the flow rate of water reaching different locations in a target area. Through the water flow distribution map, you can see the distribution of water in the target area, concentrated areas, and blank areas (i.e., areas where no water is reached). The water flow distribution map can be used for the design of the distribution location of fire sprinkler heads in the target area, and it can also be used to assess the fire protection range of the target area, etc., without being limited here.

[0035] In one implementation, the water flow distribution map may take the form of a spatial distribution map such as a heat map, contour map / isoline map, three-dimensional surface map, or bubble chart, as an example and not a limitation. Figure 3 The image shown is a schematic diagram of the water flow distribution in the form of a heat map, which reflects the water flow distribution on a first-floor slab.

[0036] In one implementation, the reachable locations and corresponding reachable water flow rates of the target area can be converted into data for a corresponding spatial distribution map. Then, based on the data from the spatial distribution map, a corresponding spatial distribution map can be generated to obtain the water flow rate distribution map of the target area. For example, the data for a heatmap-style spatial distribution map can be RGB color values, and the data for a bubble chart-style spatial distribution map can be bubble positions and bubble sizes; specific details are not limited here.

[0037] The method for generating a water flow distribution map provided in the above embodiments can accurately simulate the reachable position and reachable water volume of fire sprinkler heads in a specific area by detecting the collision between the water spray trajectory of the fire sprinkler head and potential obstructions, thereby generating an intuitive water flow distribution map, so that the processing based on the actual coverage of the water spray in a specific area also has a more accurate data basis.

[0038] Next, the specific implementation method for generating the water spray flow distribution map will be explained.

[0039] In one embodiment, the step of performing collision detection on the water spray trajectory of each target nozzle and potential obstructions based on first model data, second model data, first location information, and nozzle attribute parameters to determine the reachable water spray location and the reachable water spray volume of the target area includes: performing meshing processing on the surface of the target area based on the first model data to obtain mesh data of the target area; and performing collision detection on the water spray trajectory of each target nozzle and potential obstructions based on the mesh data, second model data, first location information, and nozzle attribute parameters to determine the water spray accessibility information of each mesh in the mesh data and the reachable water spray volume of the reachable mesh; wherein the reachable mesh indicated by the water spray accessibility information is the reachable water spray location of the target area.

[0040] The target area is the area where the water flow distribution needs to be identified. Through the gridding process of this implementation method, the irregular first model data can be converted into regular grid data. This does not affect the identification of the water flow distribution, but also reduces the difficulty of data processing and improves processing efficiency. It is a clever processing method.

[0041] As an example, and not a limitation, if the target area is a floor slab of any floor in the target building, then the grid data of the target area represents the surface of that floor slab facing the target nozzle, corresponding to the ground of that floor slab. When meshing the surface of the target area, the target surface of the first model data can be divided into grids of corresponding specifications according to a preset specified precision. The higher the precision, the more grids in the grid data; however, no specific limitation is made here.

[0042] For example, assuming the actual physical size of the target area surface is 10m×10m and the preset specified accuracy is 100mm, then the grid data of the target area will contain 100×100 grids, and the side length of each grid is 100mm. The specific dimensions are not limited here.

[0043] The grid data can be used to record the position of each grid on the surface of the target area relative to any / specified target nozzle. Specifically, the horizontal and vertical distances of each grid on the surface of the target area from the center of any / specified target nozzle can be recorded. The specified target nozzle can be the nearest target nozzle or a nozzle that can be reached by water spray, etc., and there are no specific limitations here.

[0044] For example, Figure 3As shown, the intersection of the red curve and the green horizontal line represents one of the grids on the surface of the target area. The grid data can record the d-value and h-value of the grid, where the d-value represents the horizontal distance of the grid from the center of the specified target nozzle, and the h-value represents the vertical distance of the grid from the center of the specified target nozzle.

[0045] After obtaining the grid data, collision detection of potential obstructions can be performed on each grid and the water spray trajectory to determine whether each grid is a water spray reachable location and the reachable water spray volume of the reachable location. The information on whether each grid is a water spray reachable location serves as the water spray reachability information for the corresponding grid.

[0046] In one implementation, when performing collision detection on the water jet trajectory of each target nozzle against potential obstructions based on grid data, second model data, first location information, and nozzle attribute parameters, each grid can be used as a water jet landing point. By using the original trajectory equation corresponding to the grid, it can be determined whether the water jet trajectory of each reachable nozzle in the grid collides with a potential obstruction. If a collision occurs, the grid is determined to be an unreachable grid; if no collision occurs, the grid is determined to be a reachable grid. In another implementation, the reachable water volume of a reachable grid can be determined based on the number or flow rate of reachable nozzles in the reachable grid; details are not elaborated here.

[0047] In one implementation, the step of performing collision detection on the water jet trajectory of each target nozzle and potential obstructions based on grid data, second model data, first location information, and nozzle attribute parameters to determine the water jet accessibility information of each grid in the grid data and the achievable water jet volume of the accessible grid includes: matching a first grid within the coverage range of each target nozzle from the grid data according to the coverage range parameter of the corresponding target nozzle in the nozzle attribute parameters; identifying at least one target nozzle covering any first grid as the first nozzle corresponding to the first grid; and determining the first nozzle based on the original trajectory equation and grid data. The second position information of each first grid is used to determine the water spray trajectory corresponding to each first grid and each first nozzle; the water spray trajectory corresponding to each first grid and each first nozzle is used to perform collision detection with potential obstructions to determine the water spray accessibility information of each first grid in the grid data and the achievable water spray volume of the water sprayable grid; wherein, the first grid that indicates that it has not collided with a potential obstruction in the water spray accessibility information is a water sprayable grid, the first grid that indicates that it has collided with a potential obstruction in the water spray accessibility information, and the grids other than the first grid in the grid data are water spray unreachable grids.

[0048] The coverage range parameter of the target sprinkler head is one of the inherent sprinkler head attribute parameters. It represents the water spray coverage range of the target sprinkler head under ideal conditions. Like other sprinkler head attribute parameters, the coverage range parameter can also be specified or customized by the user, or obtained from the sprinkler head manufacturer's parameters. No specific restrictions are made here.

[0049] In this embodiment, firstly, based on the water spray coverage range of the target nozzle, a grid that the target nozzle can ideally cover is matched as the first grid corresponding to the target nozzle. Since the water spray coverage ranges of different target nozzles may overlap, that is, the same water spray reachable position may be sprayed by one or more target nozzles, this embodiment determines the water spray reachable nozzle of each first grid as the first nozzle corresponding to the first grid, so as to facilitate subsequent collision detection for each water spray reachable nozzle of the first grid and obtain more accurate detection results.

[0050] The first nozzle corresponding to the first grid is the target nozzle that the water spray can reach under ideal conditions. That is, the water spray coverage includes the target nozzle corresponding to the first grid. In this embodiment, after determining the first nozzle corresponding to the first grid, the first grid can be used as the water spray landing point. The water spray trajectory corresponding to each first grid and each first nozzle is determined for subsequent collision detection with potential obstructions to obtain more accurate detection results.

[0051] Taking the original trajectory equation of the target nozzle as an example, assuming the vertical distance between a first grid and the center of one of the first nozzles is 2 and the horizontal distance is 3, then the water jet trajectory corresponding to the first grid and the first nozzle is as follows:

[0052] The shape of the water jet trajectory is as follows Figure 4 As shown, Figure 4 In the diagram, the origin of the coordinate system is the location of this first center. Figure 4 It is the shape of the above equation rotated 90° clockwise around the origin, in the form of a parabola, but the specific shape is not limited here.

[0053] As can be seen from the above water spray trajectory, when x=d=3, y=h=2. That is, the above water spray trajectory can verify that any point in space can be the landing point of the water spray, that is, the landing point of the water spray is on the above water spray trajectory.

[0054] For each first nozzle corresponding to each first grid, the corresponding water jet trajectory can be obtained through the corresponding original trajectory equation. For each water jet trajectory, collision detection is performed with potential obstructions. If the water jet trajectory of any first nozzle corresponding to the first grid does not collide with a potential obstruction, then the first grid is a water jet reachable grid. If all water jet trajectories corresponding to the first grid collide with potential obstructions, then the first grid is a water jet unreachable grid.

[0055] In the grid data, grids other than the first grid are not within the water spray coverage of any target nozzle. Therefore, they can be identified as unreachable grids and do not need to participate in collision detection. This allows for more efficient and accurate collision detection results.

[0056] In one embodiment, the step of performing collision detection between the water jet trajectory corresponding to each first grid and each first nozzle and potential obstructions to determine the water jet accessibility information of each first grid in the grid data and the achievable water jet volume of the water jet accessible grid includes: performing collision detection between the water jet trajectory corresponding to each first grid and each first nozzle and potential obstructions; determining all first grids whose corresponding water jet trajectory does not collide with potential obstructions as water jet accessible grids; determining any first grid whose corresponding water jet trajectory collides with potential obstructions as water jet unreachable grids, thereby obtaining the water jet accessibility information of each first grid; calculating the first water jet volume of each first nozzle corresponding to each water jet accessible grid using the nozzle flow rate formula in the nozzle attribute parameters of the first nozzle corresponding to each water jet accessible grid; and for each water jet accessible grid, superimposing the first water jet volumes of all corresponding first nozzles to obtain the achievable water jet volume of each water jet accessible grid.

[0057] In this embodiment, collision detection is performed on the water spray trajectory of each first grid and each corresponding first nozzle against potential obstructions to determine the reachable and unreachable grids within the first grid, thereby obtaining the water spray reachability information for each first grid. In one embodiment, during collision detection, the second model data of the potential obstruction can be used to identify whether the water spray trajectory intersects with the surface of the potential obstruction. If they intersect, a collision is determined to have occurred; otherwise, no collision is determined to have occurred. Other collision detection methods can also be used, which will not be explored here.

[0058] The nozzle flow rate formula can be used as one of the inherent nozzle attribute parameters of the target nozzle. It represents the flow rate / volume of water sprayed by the target nozzle at any point in space under ideal conditions. Like other nozzle attribute parameters, the nozzle flow rate formula can also be specified or customized by the user, or obtained from the parameters of the sprinkler head manufacturer. The specifics are not limited here.

[0059] As an example, and not a limitation, one possible formula for nozzle flow rate is as follows:

[0060] Where q represents the flow rate / volume of water sprayed by the corresponding target nozzle at any point in space, d represents the horizontal distance between any point in space and the center of the corresponding target nozzle, and s represents the coverage area / radius of the corresponding target nozzle.

[0061] Based on the nozzle flow rate formula, the first spray volume of each first nozzle corresponding to each reachable water grid can be calculated. Then, by superimposing the first spray volumes corresponding to each reachable water grid, the reachable spray volume of each reachable water grid can be obtained.

[0062] In one embodiment, the step of generating a water flow distribution map of a target area based on the reachable water spray locations and the reachable water spray volume of the reachable water spray locations includes: generating an original canvas corresponding to the target area based on first model data of the target area; generating a heat map in the original canvas corresponding to the reachable water spray locations and the reachable water spray volume of the reachable water spray locations of the target area based on a preset mapping relationship between water spray volume and color value, thereby obtaining a water flow distribution map of the target area.

[0063] In this embodiment, the generated water flow distribution map is a heat map. In one embodiment, when generating the water flow distribution map of the heat map, the water flow distribution map of the target area can be generated by a preset heat map generation algorithm, which will not be elaborated here.

[0064] Different water spray volumes correspond to different color values, and the two are associated through a preset mapping relationship. When generating a water spray volume distribution map of the target area, the original canvas of the target area can be generated first. The pixels in the original canvas of the target area have a corresponding relationship with different positions in the target area. For example, position A in the target area corresponds to pixel B or pixel set B in the original canvas. The specifics are not limited here.

[0065] After generating the original canvas, the color value of the pixel corresponding to the reachable water spray position in the target area can be determined based on the reachable water spray position and the reachable water spray volume in the reachable water spray position. If there is no pixel corresponding to the reachable water spray position in the original canvas, the color can be smoothly transitioned through color interpolation and other methods to obtain the water spray flow distribution map of the target area, making the water spray flow distribution more intuitive.

[0066] In one embodiment, the step of generating a water flow distribution map of a target area based on the reachable water spray locations and the reachable water spray volume of the reachable water spray locations includes: generating an original canvas corresponding to the target area based on grid data of the target area; wherein each grid in the grid data corresponds to at least one pixel in the original canvas; determining the target color value corresponding to the reachable water spray volume of each reachable water spray grid in the grid data according to a preset mapping relationship between water spray volume and color value, filling the target color value into the pixel corresponding to the reachable water spray grid in the original canvas to obtain a first canvas; for pixels in the first canvas that are not filled with color values, performing a smooth transition color value calculation on the color values ​​around the pixel, filling the first canvas according to the calculation result, and obtaining a water flow distribution map of the target area.

[0067] In one embodiment, the step of calculating a smooth transition color value for the color values ​​surrounding a pixel that is not filled with a color value in the first canvas, and filling the first canvas according to the calculation result to obtain a water flow distribution map of the target area includes: calculating a smooth transition color value as the calculation result for the color values ​​surrounding the pixel that is not filled with a color value in the first canvas; and filling the first canvas with the calculation result to obtain a water flow distribution map of the target area.

[0068] In one embodiment, the step of meshing the surface of the target area based on the first model data to obtain the mesh data of the target area includes: dividing the surface area of ​​the target area in the first model data into meshes of corresponding sizes according to the actual physical size of the target area and a preset specified precision, thereby obtaining the mesh data of the target area; wherein, the size of each mesh in the mesh data is the same as the specified precision.

[0069] In this embodiment, the preset specified precision is used to indicate the size / specification of each grid when performing gridding processing. Based on the preset specified precision and the actual physical size of the target area, the number of grids required to divide the surface of the target area can be calculated. Based on the determined grid size / specification and number, the surface of the target area can be gridded to obtain the grid data of the target area. This allows the identification of the water flow distribution to be achieved based on different precisions, making it more flexible and versatile.

[0070] In one embodiment, the method further includes: acquiring a target building model; identifying a model in the target building model whose location is between the target area and the location of the target nozzle as a potential obstruction model; and acquiring second model data of the potential obstruction from the target building model.

[0071] In this embodiment, the target area, potential obstructions, and target nozzles are all objects within the target building. In this embodiment, it is only necessary to obtain the target building model, determine / select the target area and target nozzles in the target building model, and then match the potential obstruction model in the target building model to obtain the second model data of the potential obstruction.

[0072] Specifically, the model of a potential obstruction is a model that is located between the target area and the target nozzle. For example, when the target area is a floor slab, the potential obstruction can be a component such as a wall, beam, column, or pipeline in the target building. No specific limitation is made here.

[0073] For the corresponding method embodiments described above, see [link to relevant documentation]. Figure 5 The diagram shows a device for generating a water flow distribution map. The device includes: an acquisition module 52, used to acquire first model data of a target area, second model data of potential obstructions, and first position information and nozzle attribute parameters of at least one target nozzle; wherein the nozzle attribute parameters include an original trajectory equation, which indicates the relationship between the water flow trajectory of the corresponding target nozzle and any position in space; a detection module 54, used to perform collision detection on the water flow trajectory of each target nozzle and the potential obstruction based on the first model data, the second model data, the first position information, and the nozzle attribute parameters, to determine the reachable water flow position and the reachable water flow rate of the reachable water flow position in the target area; and a generation module 56, used to generate a water flow distribution map of the target area based on the reachable water flow position and the reachable water flow rate of the reachable water flow position.
