Fig. 2E is a schematic diagram illustrating 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 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 or not 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 flow-in end modes are judged in sequence through the water flow-out end of the previous stage, namely the water flow-in end of the next stage;
s2-3, reconstructing a first spraying tree according to the spraying pipes, wherein the first spraying 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 produced by the latest stage judges whether a spray header is connected, and the connection modes of the spray header have two types: 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, circulating S2-3 and S2-4: gradually searching, interrupting 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 all the element pipes only have water outlet ends connected with the spray headers and do not have any other connection;
s2-6, determining the 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 spray heads needing water supply for each sub-element pipe after the unreasonable data and the invalid data are eliminated. The calculation mode is that the spray heads of the spray heads and the spray heads on all the subunit pipes comprise the subunit pipes of the subunit 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 mainly according to the spraying pipe tree structure with the two-dimensional information output in the S2 and the three-dimensional data input by the spraying system modeling in the 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 and Y coordinates according to metadata startPoint at a water inlet end and EndPoint at a water outlet end in the spraying tree, determining a Z coordinate according to the sum of the pipeline offset and the three-dimensional height of the floor to obtain a three-dimensional pipeline EndPoint model coordinate, and establishing a pipeline model of a corresponding pipe diameter in Revit according to pipe diameter information determined by S2-6;
s3-2, generating a spray header: the coordinate of the spray head is calculated by the way that the direct spray head number in the element pipe data is one according to the three-dimensional coordinate of the water outlet end point, the offset of the spray head and the upward offset of the spray head at the three-dimensional coordinate of the water outlet end point when the spray head type of the real model is the upward spray, and the downward offset at the three-dimensional coordinate of the water outlet end point when the spray head type of the real model is the downward offset, and a spray head model is created at the coordinate point of the spray head according to the corresponding group of the spray head in Revit;
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 the step S3-2 in Revit, wherein the pipe diameter is DN25 with the minimum diameter;
s3-4, pipe fitting generation: and in the element pipe data, a pipe fitting is required to be established at the three-dimensional position of the water outlet end, the pipe fitting is specifically a reducer, an elbow, a tee or a cross, 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 is specifically as follows:
reducing the size: if a pipe diameter DN80 of a sub-elementary pipe is arranged at the position of an elementary pipe water outlet of DN100 and no spray head is arranged, 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 element pipe of DN25 has no element pipe and has an upper spray head and a lower spray head, a DN25 positive tee joint is generated;
a tee joint: if two sub-elementary tubes are arranged at the position of the water outlet of the elementary tube 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.
