Fig. 2E is a schematic view of an auxiliary simple spraying model according to an embodiment of the present invention; fig. 2F is a schematic diagram of a simple spray model with a spray header according to an embodiment of the present invention. Wherein, establishing the spraying system model data may include, but is not limited to, the following steps:
s2-1, determining a main pipe: and determining a first CAD line entity as a main pipe graphic element according to the selected spray pipe layer and the water inlet main pipe position point, such as 1 in the 2E schematic diagram. Then, combining the line entities on the same layer and on the same straight line into a first-stage spraying trunk pipe FirstPIPe through a reasonable combination distance, wherein parts 1, 2 and 3 in a 2E schematic diagram are represented as first-stage trunk pipes;
s2-2, determining the water flow direction: and judging whether the end part of the main pipe is in accordance with one end without connection and the other end with connection according to the main pipe data obtained in the step S2-1, wherein water flows to the connecting end 1-2 from the non-connection state. Other water flows through the water outflow end of the previous stage, namely the water inflow end of the next stage in turn;
s2-3, reconstructing a first spray tree according to the spray pipes, wherein the first spray tree comprises a first element pipe and a first sub-element pipe: breaking the last-level element pipe of the formed spray tree by intersecting the first-level main pipe FirstPoint with other pipelines (4, 5, 6 and 7) to form new first-level element pipe data (1, 2 and 3), changing the hierarchical relation of the first-level element pipe data into a sub-element pipe with 2 being 1 and a sub-element pipe with 3 being 2 according to the water flow direction, and simultaneously adding the broken pipelines into the spray tree in sequence, wherein the broken pipelines are 4 sub-element pipes with 1, 5 and 6 sub-element pipes with 2 and 7 sub-element pipes with 3;
s2-4, reconstructing a second spray tree according to the spray header, wherein the second spray tree comprises a second element pipe and a second sub-element pipe: the element pipe that the latest one-level produced judges whether there is spray header that links to each other, and the mode that the spray header is connected has two kinds: one is that the spray header connected with the water outlet end is continuously searched for other connected next-level pipelines through the spray header to establish next-level element pipe data, for example, 4-2 is a 4-1 subelement pipe in fig. 2F, and the other is that the spray header is at a certain position in the middle of the drawing line entity, at this time, the spray header needs to be interrupted at the position of the spray header, the data of the element pipe at the current level is changed, and the hierarchical relationship among the interrupted element pipe data is established according to the water flow direction, for example, 9 in fig. 2E is a 6 subelement pipe, if 6 has a spray header in the middle, the step is changed into 6-1 subelement pipe 6-2 and 6-2 subelement pipe 9 in fig. 2F;
s2-5, loop S2-3, S2-4 steps: gradually searching, breaking and establishing a data hierarchy for the newly generated first-stage element pipes step by step according to the modes of S2-3 and S2-4 until the path searching is finished when only the water outlet ends of all the element pipes are connected with the spray header and no other connection exists;
s2-6, determining pipe diameter: and checking and eliminating unreasonable data and invalid data according to the output data obtained in the step S2-5, and calculating the total number of the nozzles needing water supply for each sub-unit pipe after elimination. The calculation mode is the spray head of the spray head and the spray heads on all the daughter pipes, including the daughter pipes of the daughter pipes. And determining the pipe diameter of each element pipe from the pipe diameter comparison table according to the total number of the nozzles. Namely, when the first element pipe and the first sub element pipe, the second element pipe and the second sub element pipe only have water outlet ends and are only connected with spray heads, the total number of the spray heads which need to supply water for each sub element pipe is calculated.
And S3, generating a three-dimensional spraying system model.
And S3, establishing a three-dimensional spraying system model according to the spraying pipe tree structure with two-dimensional information output in S2 and the three-dimensional data input by the spraying system modeling in S1. Fig. 2G is a schematic flow chart illustrating generation of a three-dimensional spray system model according to an embodiment of the present invention.
Wherein generating the three-dimensional spray system model may include, but is not limited to, the steps of:
s3-1, generating a horizontal spray pipe: confirming X, Y coordinates according to metadata StartPoint and EndPoint two-dimensional coordinates in a spraying tree at a water inlet end and an water outlet end, confirming a Z coordinate according to the sum of the pipeline offset and the three-dimensional height of a floor, obtaining three-dimensional pipeline EndPoint model coordinates, and establishing a pipeline model of a corresponding pipe diameter in Revit by adding pipe diameter information determined by S2-6;
s3-2, generating a spray header: if the number of the direct spray heads in the element pipe data is one, the spray heads are upwardly offset at the three-dimensional coordinates of the water outlet end points according to the three-dimensional coordinates of the water outlet end points, the offset of the spray heads and the type of the spray heads of the real model, and the spray heads are downwardly offset at the three-dimensional coordinates of the water outlet end points according to the lower spray, so that the coordinates of the spray heads are calculated, and a spray head model is created at the coordinate points of the spray heads according to the corresponding group of the spray heads in Re;
s3-3, generating a vertical spray pipe: creating a vertical pipeline model between the spray header and the branch pipe according to the three-dimensional coordinate position point of the spray header and the three-dimensional coordinate of the water outlet end of the branch pipe generated in S3-2 in Revit, wherein the pipe diameter is DN25 with the minimum pipe diameter;
s3-4, pipe fitting generation: in the element pipe data, a pipe fitting needs to be established at the three-dimensional position of the water outlet end, wherein the pipe fitting is specifically a big end, a small end, an elbow, a tee joint or a four-way joint, the type of the pipe fitting is determined according to the number of the element pipes in the element pipe data, the number of direct spray heads and the connected pipe diameter data, and a corresponding pipe fitting model is established.
It should be noted that the rule for generating the pipe fittings is specifically as follows:
reducing the size: if a water outlet of a primary pipe of DN100 is provided with a pipe diameter DN80 of a secondary primary pipe and no spray head is provided, a reducer with a corresponding pipe diameter is generated;
bending: if the water outlet of the primary pipe of DN25 has no secondary pipe and has a direct nozzle, a DN25 elbow is generated;
a positive tee: if the water outlet of the primary pipe of DN25 has no secondary pipe and has an upper nozzle and a lower nozzle, a DN25 positive tee is generated;
a tee joint: if two sub-elementary tubes are arranged at the position of the elementary tube water outlet of DN50, and the tube diameters are DN50 and DN30 respectively, a tee joint with the corresponding tube diameter is generated;
four-way: if three sub-elementary tubes are arranged at the position of the elementary tube water outlet of DN100 and no spray head is arranged, a four-way tube with the corresponding tube diameter is generated.
