Step S102: and determining the spray heads and the pipelines in the construction drawing information.
After the building drawing information is acquired, in step S102, the nozzles and the pipelines in the building drawing information are determined. Optionally, data corresponding to the spray heads and the pipelines can be screened from the construction drawing information in a data screening mode; optionally, the image corresponding to the nozzle and the pipeline may also be identified in the image corresponding to the building drawing information by means of image identification, for example, in the CAD drawing, the model is composed of CAD elements, specifically including a point element, a line element, a block element, and the like, where for the spray pipeline model, the pipeline is expressed by the line element, the nozzle is expressed by the block element, when the nozzle and the pipeline in the building drawing information are determined, the line element and the block element in the building drawing information are extracted, specifically, the CAD elements therein are filtered according to the drawing area determined by the user, and the line element and the block element are retained; then, the extracted block elements are further screened according to the shape and the size of the sprayer, the block elements which accord with the preset shape and the preset size are determined to be the sprayer, the preset shape and the preset size can be set based on the legend corresponding to the sprayer, and the line elements which have the connection relation with the sprayer are further determined to be the pipelines after the sprayer is determined according to the extracted line elements. Optionally, after the step of extracting the line elements and the block elements in the construction drawing information, when the spray head and the pipeline are determined, the information such as the layers and colors of the block elements and the line elements may be simultaneously combined for determination, for example, determining that a plurality of block elements which conform to a preset shape and size and belong to the same layer and/or have the same color are the spray head, and if a plurality of line elements which have a connection relationship with the spray head and belong to the same layer and/or have the same color are determined to be the pipeline, the accuracy of identifying the spray head and the pipeline is improved, and the accuracy of calculating the engineering quantity of the spray pipeline is further improved.
Step S103: and constructing a tree structure according to the geometric position relation and the connection relation of the pipeline and the spray head.
Specifically, the spraying system comprises a main pipeline, a branch pipeline and equipment arranged at the tail end of the branch pipeline, a water inlet is used as the starting end of the spraying system, a spray head is used as the tail end of the spraying system, the pipeline and the spray head are integrally communicated loops, and the pipeline and the spray head can be abstracted to be in a tree structure. Optionally, when a tree structure is constructed, the intersection position of the pipeline is used as a branch node of the tree structure, the nozzle is used as a leaf node of the tree structure, the tail end of the pipeline which is not connected with the nozzle is used as a root node of the tree structure, specifically, after the branch node and the leaf node are determined, branches are traced back according to the leaf node, then a trunk is traced back, finally, a loop which is clearly communicated through a geometric position relation and a connection relation is used, for the tail end of the pipeline which is not connected with the nozzle, the tail end belongs to a water inlet of the spraying system, the water inlet is used as the root of the tree structure, and finally, the tree structure of the spraying system is formed through step-by-step node.
Step S104: and acquiring attribute information and professional specification information of the pipeline.
Specifically, the attribute information of the pipeline includes a pipeline model, a pipeline arrangement style, material information of the pipeline, a connection mode of the pipeline and the spray head, and the like, and all pipeline limiting information influencing the pipeline diameter belongs to the attribute information of the pipeline in the invention; the professional specification information of the pipeline comprises pipeline pipe diameter ranges specified by the pipeline under different danger grade requirements and different use places, and the like, and the industrial specification aiming at the pipe diameters of the pipeline in the spraying system belongs to the professional specification information of the pipeline.
The system comprises a pipeline, a system and a display device, wherein a user can set the attribute information of the pipeline and the professional specification information to be followed by the pipeline according to actual requirements, for example, a configuration interface for setting the attribute information and the professional specification information of the pipeline is provided, the attribute information and the professional specification information of the pipeline are displayed through the interface, meanwhile, in the interface, the user can configure and adjust the attribute information and the professional specification information of the pipeline in the construction drawing information through selection operation and/or information input operation, and the system obtains the attribute information and the professional specification information of the pipeline based on the operation of the user.
Optionally, an interface can be configured through double-window design, common modification interactive controls are placed in the main window, regular settings are placed in the sub-windows, the parent window controls the sub-windows to be visible and invisible, and the life cycles of the two windows are consistent. The master window may control the type switching of the "modify" command state. All tables and controls in the configuration interface follow a Model/View principle, the display operations of a form, a preview and the like can only directly display data and can not perform correction display different from data authenticity, the what you see is what you get is ensured, the common attributes of the pipelines are provided for a user to be set in the configuration window, and the one-by-one modification after identification, namely the attributes of the pipelines are displayed in the configuration window to set the attributes of the pipelines, is avoided.
Step S105: and calculating the pipe diameter of the pipeline according to the tree structure, the attribute information and the professional specification information.
Specifically, in one case, the number of the nozzles connected to each pipeline may be determined according to the tree structure, for example, a certain pipeline may be branched into three branches, each branch is connected with two nozzles, the number of the nozzles connected to the pipeline is six, the number of the nozzles connected to the pipeline in which each branch is located is two, and then the pipe diameter of the pipeline is determined on the premise of connecting the corresponding number of the nozzles according to the attribute information and the professional specification information of the pipeline. Optionally, the number of the nozzles connected with the pipeline is determined according to the tree structure, then when the pipeline is determined to have the capacity of connecting the number of the nozzles according to the professional specification information, the corresponding pipe diameter range is obtained, and finally the pipe diameter of the pipeline is determined in the first pipe diameter range according to the attribute information. Therefore, when the user adjusts the attribute information and the professional specification information, the calculated pipe diameter can be changed correspondingly.
Or, in another case, the corresponding relation between the number of the nozzles to be connected to the pipeline and the pipe diameter is determined according to the attribute information and the professional specification information, then the number of the nozzles actually connected to the pipeline is determined based on the tree structure, and finally the pipe diameter of the pipeline is determined according to the corresponding relation between the number of the nozzles and the pipe diameter and the number of the nozzles actually connected to the pipeline, so that when the attribute information and the professional specification information are adjusted by a user, the calculated pipe diameter can be changed correspondingly.
In the method for calculating the engineering quantity of the spraying pipeline provided by the embodiment, the construction drawing information is firstly obtained, then the spray head and the pipeline are determined in the construction drawing information, the tree structure is constructed according to the geometric position relation and the connection relation of the pipeline and the spray head, the attribute information and the professional specification information of the pipeline are further obtained, finally the pipe diameter of the pipeline is calculated according to the tree structure, the attribute information and the professional specification information, and the pipe diameter is determined relatively and completely depending on the label in the drawing. When a user modifies the attribute information as required and the pipeline needs to meet the professional specification, the pipe diameter calculation result of the pipeline is correspondingly the modified calculation result, so that the calculation of the engineering quantity of the spraying pipeline is more flexible, and the user can conveniently adjust and design the spraying pipeline.
Optionally, in an embodiment, before the step of calculating the pipe diameter of the pipeline according to the tree structure, the attribute information, and the professional specification information, the method for calculating the engineering quantity of the spray pipeline further includes: carrying out external expansion on the pipeline according to the shape of the pipeline to obtain an external expansion area; extracting a digital mark in the outward expansion area; and when the digital identification is extracted, identifying the digital identification to obtain the pipe diameter of the pipeline, wherein in the calculation method of the spraying pipeline engineering quantity, when the digital identification cannot be extracted, the pipe diameter of the pipeline is calculated according to the tree structure, the attribute information and the professional specification information.
Specifically, this embodiment provides two ways of determining the pipe diameter of the pipeline, that is, determining the pipe diameter by using the digital identifier of the pipeline in the drawing, that is, performing the external expansion of the pipeline according to its shape, presetting a parameter threshold for limiting the size of the external expansion region, performing the external expansion within the threshold to obtain the external expansion region, extracting the digital identifier from the external expansion region for identification, using the pipe diameter identified by the digital identifier extracted from the external expansion region as the pipe diameter of the pipeline, and calculating the pipe diameter of the pipeline according to the tree structure, the attribute information, and the professional specification information when the digital identifier is not extracted.
By adopting the method for calculating the engineering quantity of the spraying pipeline provided by the embodiment, the pipe diameter can be determined based on the pipe diameter of the pipeline marked in the original paper, and for the pipeline which cannot be determined based on the original paper, the pipe diameter can be further determined based on the tree structure representing the spraying system loop and the attribute information and professional specification information of the pipeline set by the user, so that the configuration operation of the user can be reduced, and the calculation accuracy can be improved.
Further optionally, when the digital identifier is not extracted, determining the pipe diameter of the pipeline within the first pipe diameter range according to the attribute information includes: determining an upstream pipeline and a downstream pipeline of the pipeline to obtain a second pipe diameter range, wherein the end point value of the second pipe diameter range is the pipe diameter of the upstream pipeline and the pipe diameter of the downstream pipeline; and determining the pipe diameter of the pipeline in the intersection area of the first pipe diameter range and the second pipe diameter range according to the attribute information.
Specifically, based on the characteristics of loop circulation, the pipe diameter of a pipeline is smaller than that of an upstream pipeline and larger than that of a downstream pipeline, so that for a certain pipeline, when no digital identifier is extracted, the upstream pipeline and the downstream pipeline of the pipeline are determined by a tree structure, namely, one pipe diameter range of the pipeline is determined, named as a second pipe diameter range in the invention, then the intersection area of the first pipe diameter range and the second pipe diameter range is determined, and the pipe diameter of the pipeline is determined in the intersection area.
By adopting the method for calculating the engineering quantity of the spraying pipeline provided by the embodiment, the pipe diameter of the pipeline is limited by the pipe diameter of the upstream pipeline and the pipe diameter of the downstream pipeline, and the accuracy of calculating the pipe diameter of the pipeline can be further improved.
Optionally, in an embodiment, before constructing the tree structure according to the geometric position relationship and the connection relationship between the pipeline and the spray head, the method for calculating the engineering quantity of the spray pipeline further includes: modifying the spray head and/or the pipeline in response to the modifying operation;
specifically, in the process of calculating the engineering quantity of the spraying pipeline, a user can modify the spray heads and/or the pipelines, specifically, the modification can include adding pipelines, deleting pipelines, modifying pipeline positions, adding spray heads, deleting spray heads, modifying spray head positions, modifying pipeline pipe diameters and the like, for example, two fire zones can be communicated by adding and/or deleting selected pipelines; aiming at the non-standard drawing, a pipeline is additionally drawn to communicate the two fire-proof subareas; the identification content may be manually adjusted for incorrect pipeline number identification.
By adopting the method for calculating the engineering quantity of the spraying pipelines, a user can modify the spray heads and/or the pipelines in the spraying system before constructing the tree structure, so that the user can modify or flexibly design the spraying system on the basis of original drawing paper and obtain the calculation result of the engineering quantity of the spraying pipelines.
Optionally, in an embodiment, after the step of constructing the tree structure according to the geometric position relationship and the connection relationship between the pipeline and the spray head, the method for calculating the engineering quantity of the spray pipeline further includes: the sum of the lengths of all the pipelines in the tree structure is calculated.
Specifically, after the tree structure is obtained, the sum of the lengths of all pipelines in the tree structure is calculated, that is, the length of the pipeline in the spraying system is obtained, so that the influence of redundant line elements in a drawing or wrong pipeline setting on the calculation of the length of the pipeline is avoided.
