Description

Technical Field

[0001] The present invention belongs to the field of rail transit technology, and more specifically, relates to an intelligent design method and system for water supply, drainage and fire protection in a rail transit section. Background Art

[0002] With the rapid development of the economy and society and the continuous acceleration of urbanization, transportation demand has also increased accordingly. Rail transit, with its significant characteristics of large capacity and high efficiency, plays an important role in the urban transportation system. Water supply and drainage and fire protection plan design are important links to ensure the safe operation of rail transit systems such as subways. For a long time, the water supply and drainage and fire protection plan design of rail transit has mainly relied on traditional computer-aided design (CAD) software, with many manual drawing operations, which has the disadvantages of long time consumption and low production efficiency.

[0003] In order to further improve the design efficiency, some intelligent design software has been developed in recent years. However, most of the existing software, such as Autodesk Revit, is mainly suitable for water supply and drainage and fire protection design of building structures. Modeling is required before design, which has a large workload. In addition, there is a lack of automatic and accurate positioning and drawing of rail section pipes and accessories such as fire hydrants, valves and other fire protection accessories. The drawing process also lacks intuitive guidance, which affects the design accuracy and production efficiency. Summary of the invention

[0004] In view of the above defects or improvement needs of the prior art, the present invention provides a method and system for intelligent design of water supply, drainage and fire protection in rail transit sections. Through computer-aided design compilation and CAD interface and driver program, a special drawing software independent of CAD is developed to realize fast plane drawing, batch fast one-key drawing, batch marking, and automatic generation of engineering quantity statistics table for the plane layout of water supply and drainage and fire protection in sections, which greatly reduces repetitive operations and improves design efficiency and accuracy.

[0005] In order to achieve the above object, according to one aspect of the present invention, the present invention provides a rail transit section water supply and drainage and fire protection intelligent design method, comprising the following specific steps:

[0006] S100: Import the existing interval structure base map into the design software, hide or clean up unnecessary layers or elements on the base map, and obtain the processed structure base map;

[0007] S200: Based on the processed structural base map, input the design parameters of the interval fire protection plan, identify the interval contour line based on the software built-in programming command to locate the fire protection pipeline, calculate the fire hydrant mileage, determine the position of the fire hydrant and the inspection valve, call the software built-in graphic element library, automatically draw the fire protection pipeline and insert the fire hydrant and inspection valve, generate the interval fire protection plan, and automatically generate the pipeline annotation and fire hydrant mileage annotation according to the built-in graphic element attributes based on the software built-in programming command;

[0008] S300: Call the built-in interval main engineering material table template, identify the quantity and specification model attributes of all drawing elements in the drawing, and automatically generate the main engineering quantity table for this interval.

[0009] Furthermore, the step S200 includes the following specific steps:

[0010] S201: Open the interval plan design software and set parameters in the fire plan section of the software interface;

[0011] S202: Interacting with AutoCAD through the software, identifying and screening the interval contour lines of the structure base map in AutoCAD, and combining all the line segments of the interval contour into a complete line segment for path calculation;

[0012] S203: by interacting with AutoCAD through the software, based on the built-in program commands of the software and according to the set parameters, the built-in graphic element library of the software is called to generate the interval fire protection plan;

[0013] S204: Setting parameters through other pipeline panels on the software interface to complete drawing of other pipelines and accessories in the interval;

[0014] S205: Based on the software's built-in programming commands, the pipeline code and diameter marking are automatically generated according to the built-in pipeline element type and pipe diameter attributes in the drawing, and all fire hydrant mileages are batch marked according to the first fire hydrant mileage.

[0015] Furthermore, the step S203 includes the following steps:

[0016] S203-1: Fire-fighting pipeline positioning: Based on the position of the interval contour line identified in step S202, the position of the fire-fighting pipeline in the drawing is determined according to the distance between the pipeline and the interval contour, the pipeline type and the pipe diameter in the parameter setting;

[0017] S203-2: Fire hydrant and inspection valve positioning: The fire hydrant mileage is calculated based on the first fire hydrant mileage and the fire hydrant spacing in the parameter settings, according to the built-in programming logic relationship, and the relative position relationship of the inspection valve is determined by the number of fire hydrants between the two inspection valves set and the spacing between the inspection valve and the adjacent fire hydrants;

[0018] S203-3: Generation of water supply, drainage and fire protection plan: After clicking the "Generate interval fire protection pipes and valves" button, click the first fire hydrant position in the drawing through the interaction between the software and AutoCAD. Based on the built-in software program, the fire protection pipes are automatically drawn, the fire hydrant elements are inserted, the valve elements are inspected, and all fire hydrant mileages are automatically marked.

[0019] Furthermore, the logical relationship in step S203-2 is: the mileage of the N+1th fire hydrant = the mileage of the 1st fire hydrant + N×the distance between fire hydrants.

[0020] Furthermore, step S203-2 also includes: when the section line is set with long and short chains, the mileage data is revised when calculating the fire hydrant mileage. When it is a long chain, the mileage of other fire hydrants after the long chain is calculated based on the fire hydrant mileage calculated in the previous step minus the long chain number; when it is a short chain, the mileage of other fire hydrants after the short chain is calculated based on the fire hydrant mileage calculated in the previous step plus the short chain number.

[0021] Furthermore, the importing of the structural base map in step S100 is achieved by using a computer-aided language to compile a CAD interface and a driver.

[0022] Furthermore, the built-in graphic primitive library in step S203 includes fire hydrants, inspection valves, and accessory graphic blocks that are assigned specific attributes.

[0023] Furthermore, the specific attributes of the built-in graphic library blocks include block name, block type and specification model.

[0028] The engineering quantity list generation module is used to generate the main engineering quantity list of the main equipment and pipelines in the interval.

[0029] Furthermore, the basic parameters include the interval fire hydrant spacing, the number of fire hydrants between maintenance valves, the distance between the pipeline and the interval contour line, the mileage of the first fire hydrant, the mileage marking prefix, the pipeline type and diameter, and the interval length chain information parameters.

[0044] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0045] The patent of this invention develops special drawing software independent of CAD by compiling CAD interface and driver program, realizing fast plane drawing, batch fast one-click drawing, batch annotation and automatic generation of engineering quantity statistics table, and providing intuitive parameter setting and operation guidance in the software interface, which greatly reduces repetitive operations, improves design efficiency and accuracy, and provides strong support for the intelligent design of water supply and drainage and fire protection in rail transit sections.

[0046] The following is an example of an intelligent design method for water supply, drainage and fire protection in a rail transit section provided by the present application.

[0047] Embodiment 1:

[0048] The embodiment of the present invention provides a rail transit section water supply and drainage and fire protection plane intelligent design system, including:

[0049] The parameter setting module is used to input and determine the basic parameters of the interval fire protection plan design, including the interval fire hydrant spacing, the number of fire hydrants between maintenance valves, the distance between the pipeline and the interval contour line, the mileage of the first fire hydrant, the mileage marking prefix, the pipeline type and diameter, and the interval long and short chain information. These parameters are input by the user through the software interface to provide basic data for the subsequent design process and to carry out subsequent drawing and marking.

[0050] The mileage calculation and correction module is used to calculate the mileage of all fire hydrants in the section and correct it according to the section length chain information. This module uses the logical relationship to calculate the mileage of all other fire hydrants based on the first fire hydrant mileage and fire hydrant spacing set by the user. At the same time, this module also considers the characteristics of the line length chain and revises the mileage data to ensure the accuracy of the fire hydrant location. The logical relationship is: the mileage of the N+1th fire hydrant = the mileage of the first fire hydrant + N×fire hydrant spacing.

[0051] The graphics drawing module, based on the data provided by the parameter setting module, calls the built-in graphic library to realize the drawing of water supply and drainage pipes, fire hydrants, inspection valves and accessories on the drawings. This module uses the interactive function of AutoCAD and automatically calculates the coordinate data of the pipe according to the set parameters, draws polylines with pipe type and pipe diameter attributes, and realizes the insertion and positioning of fire hydrants, inspection valves and other graphics. At the same time, the fire hydrant mileage is automatically marked in the drawings based on the calculated mileage.

[0052] The construction and calling of the built-in primitive library includes the following contents:

[0053] (1) Block design and attribute definition: First, according to the drawing requirements, design and create blocks for graphics such as fire hydrants, inspection valves, and accessories. Each block is assigned specific attributes, such as block name, system type, specification model, etc. These attributes ensure the uniqueness and traceability of the block in the drawing.

[0054] (2) Creation of graphic element library: All designed graphic elements are integrated into a unified graphic element library. This graphic element library can be regarded as a built-in component of the software. Each graphic element in the graphic element library is classified and stored according to its attributes and types to facilitate subsequent retrieval and call.

[0055] (3) Block call and insertion: When you need to insert graphics such as fire hydrants, valves or accessories into the drawing, the user can select the corresponding block through the software interface. The software retrieves and extracts the corresponding block from the built-in graphic library based on the user's selection. Then, the software inserts the block into the specified position in the drawing and adjusts its size, direction, scale and other parameters as needed.

[0056] (4) Property editing and updating: After inserting a block into a drawing, the user can also edit the properties of the block as needed. For example, modify the system type, specification model, or add other relevant information. These editing operations will be directly reflected on the block and saved in the drawing file for subsequent reference and use.

[0057] (5) Library maintenance and updates: As design requirements and specifications change, the blocks in the library may need to be updated or expanded. The software provides corresponding tools and functions that allow users to easily add new blocks, modify existing blocks, or delete blocks that are no longer needed. These update operations will ensure that the library is always up to date and meets current design requirements.

[0058] The engineering quantity table generation module is used to generate the main engineering quantity table of the main equipment and pipelines in the interval. This module recognizes the design elements automatically drawn by the software, calls the built-in material statistics template, and automatically generates the main engineering quantity table of this interval, including the quantity and specification model of equipment and materials such as pipelines, fire hydrants, valves, etc. This module can be inserted into AutoCAD drawings for designers to view and check.

[0059] like Figure 1 As shown, using the above system, an embodiment of the present invention provides a flow chart of an intelligent design method for water supply, drainage and fire protection in a rail transit section, which specifically includes the following steps:

[0060] S100: Importing and processing the structural base map: importing the existing interval structural base map into the design software. The interval structural base map contains information such as the route of the interval and the position of the track. The imported interval structural base map is processed as necessary, and unnecessary layers or elements on the base map are hidden or cleared to obtain the processed structural base map, so as to simplify the subsequent design process.

[0061] S200: Drawing of interval drainage and fire protection system plan: Based on the processed structural base map, input the interval fire protection plan design parameters, identify the interval contour line based on the software's built-in programming commands to locate the fire protection pipes, calculate the fire hydrant mileage, determine the positions of fire hydrants and inspection valves, call the software's built-in graphic library, automatically draw the fire protection pipes and insert fire hydrants and inspection valves, generate the interval fire protection plan, and automatically generate pipe annotations and fire hydrant mileage annotations based on the software's built-in programming commands according to the built-in graphic attributes.

[0062] The step S200 includes the following steps:

[0063] S201: Parameter input: Open the interval plan design software and set the parameters in the fire plan section of the software interface.

[0064] The parameters mainly include: drawing scale setting, maintenance valve legend block name, interval fire hydrant spacing, number of fire hydrants between two maintenance valves, distance between pipeline and interval outline, mileage annotation prefix setting, first fire hydrant mileage, interval long and short chain information, and interval pipeline type and diameter;

[0065] The distance between fire hydrants in the section and the number of fire hydrants between two maintenance valves are regular design parameters, which are determined through refinement. Specifically, according to the "Metro Design Code", the distance between fire hydrants in underground sections should not exceed 50m, and the "Metro Design Fire Protection Standard" requires that the arrangement of valves should ensure that the number of fire hydrants closed and deactivated when inspecting the pipeline is not more than 5.

[0066] S202: Structural base map contour line recognition: The software sends a command to AutoCAD through an interface, requesting to obtain all line elements in the drawing, including straight lines, polylines, arcs and other objects that may constitute interval contour lines, and filters out lines belonging to interval contour lines according to preset conditions, and piece together all the line segments of the interval contour into a complete line segment for path calculation; the preset conditions include layer name, color, line type or other attributes.

[0067] S203: Automatic drawing of water supply and drainage and fire protection plan: through the interaction between the software and AutoCAD, based on the built-in program commands of the software and according to the set parameters, the built-in graphic element library of the software is called to generate the interval fire protection plan;

[0068] The step S203 specifically includes the following steps:

[0069] S203-1: Fire protection pipe positioning: Based on the position of the interval contour line in the drawing, the distance between the pipe and the interval contour, the pipe type and the pipe diameter in the parameter settings, determine the fire protection pipe positioning in the drawing;

[0070] The pipeline positioning is achieved by interacting with AutoCAD. The user clicks the mouse to identify the interval contour line (straight line, polyline, arc, etc.), and stores the coordinate data of each point of the interval contour line in the drawing. The coordinate data of the pipeline is calculated based on the distance between the pipeline and the interval contour line input by the user interface. If one side of the interval contour line is clicked, the interval pipeline will be drawn on that side of the contour line.

[0071] S203-2: Positioning of fire hydrants and inspection valves: The mileage of fire hydrants is calculated based on the mileage of the first fire hydrant and the distance between fire hydrants in the parameter settings, and the logical relationship of "mileage of the N+1th fire hydrant = mileage of the first fire hydrant + N×distance between fire hydrants". When the section line encounters a vertical curve, the line professional uses long and short chains to correct the mileage to ensure that the mileage difference between the left and right lines of the section is basically the same. When calculating the mileage of fire hydrants, the characteristics of the long and short chains of the line are considered and the mileage data is revised. When it is a long chain, the mileage of other fire hydrants after the long chain is based on the mileage of the fire hydrants calculated in the previous step minus the number of long chains. When it is a short chain, the mileage of other fire hydrants after the short chain is based on the mileage of the fire hydrants calculated in the previous step plus the number of short chains.

[0072] The relative position relationship of the inspection valve is determined by the number of fire hydrants between the two inspection valves and the distance between the inspection valve and the adjacent fire hydrants.

[0073] S203-3: Generation of fire protection plan: After clicking the "Generate interval fire protection pipes and valves" button, click the first fire hydrant position in the drawing through the interaction between the software and AutoCAD. Based on the built-in software program, the fire protection pipes are automatically drawn, the fire hydrant elements are inserted, the valve elements are inspected, and all fire hydrant mileages are automatically marked.

[0074] Specifically, based on the built-in primitive library and the calculated fire hydrant mileage, by interacting with AutoCAD, click to determine the location of the first fire hydrant in the drawing, the software will locate it along the fire pipe in the drawing according to the calculated fire hydrant mileage data, call the interval fire hydrant block of the built-in AutoCAD primitive library, and automatically insert the interval fire hydrant block at all fire hydrant locations; according to the type of maintenance valve entered in the user interface, the number of fire hydrants between the two maintenance valves, and the distance between the maintenance valve and the adjacent fire hydrant, the maintenance valve block is inserted on the interval fire hydrant pipe along the interval contour line. The type of maintenance valve is determined by selecting the block name in the built-in AutoCAD primitive library.

[0075] S204: Drawing of other pipes and accessories: Drawing of other water supply and drainage pipes in the interval and other valves and accessories except the fire pipe inspection valve, which is implemented in the same way as the positioning and drawing of the fire pipe, fire hydrant, and inspection valve in step S203. The specific steps are as follows:

[0076] S204-1: Positioning of other water supply and drainage pipes, valves and accessories: Select the pipe type and diameter through the other pipe module of the software interface, enter the distance between other pipes and the interval outline, and determine and draw the positioning of other water supply and drainage pipes in the drawing through the interaction between the software and AutoCAD. By interacting with AutoCAD, the user clicks in the drawing to determine the position of valves and accessories, and the software will insert other valve accessory blocks at the specified position in the drawing.

[0077] S204-2: Drawing of other valves and accessories: Use the software's built-in design element library to insert other valves and accessories into the drawing.

[0078] S205: Batch marking of fire-fighting facilities and pipeline information: Based on the software's built-in programming commands, batch update the mileage marking of fire hydrants and the marking of pipeline codes and diameters. According to the attributes of the pipeline type and diameter in the drawing, the pipeline code and diameter marking are automatically generated, and batch automatic marking can be performed by setting the marking spacing or manual marking as needed; when the mileage of fire hydrants needs to be updated, re-enter the mileage of the first fire hydrant in the parameter setting interface, and update all fire hydrant mileage markings with one click according to the logical relationship of "N+1th fire hydrant mileage = 1st fire hydrant mileage + N×fire hydrant spacing".

[0079] S300: Statistics of main engineering quantities: The software has a built-in template for the table of main engineering materials for a certain interval. By calling the built-in template, the quantity, specifications and other attributes of all pipes, valves, accessories and other elements in the drawing can be identified, and the table of main engineering quantities for this interval can be automatically generated and inserted into the AutoCAD drawing.

[0080] Embodiment 2:

[0081] like Figure 2 As shown, the following is another embodiment to illustrate a rail transit section water supply and drainage and fire protection intelligent design method provided by the present application. It includes the following steps:

[0082] Step 1: Run this software, import the AutoCAD format interval structure base map plan through the AutoCAD interface and driver of this embodiment, and enter the fire protection plan design parameters in the software interface, such as Figure 3 As shown;

[0083] Step 2: After opening the Autocad file, the software interacts with Autocad to automatically identify the connection contour line. The user clicks the interval contour line with the mouse and then clicks the outside of the interval contour line, and the interval pipeline is drawn outside the contour line;

[0084] Step 3: According to the distance between fire hydrants and the number of fire hydrants between inspection valves, the software automatically calls the built-in fire hydrant, inspection valve and accessory element library and inserts them into the corresponding positions to complete the drawing of the interval plan;

[0085] Step 4: Re-enter the first fire hydrant mileage in the parameter setting interface, and update all fire hydrant mileage labels with one click according to the logical relationship of "N+1th fire hydrant mileage = first fire hydrant mileage + N*fire hydrant spacing";

[0086] Step 5: Click other pipelines in the software parameter interface, enter relevant parameters to draw other water supply and drainage pipelines in the interval and other valves and accessories except the fire protection pipeline inspection valve;

[0087] Step 6: Click on the drawing annotation in the software parameter interface to automatically generate the pipeline code and pipe diameter annotation to complete the interval plan annotation, such as Figure 4 It is a schematic diagram of the interval fire protection plan implemented by the present invention;

[0088] Step 7: Click Material Statistics in the software parameter interface to call the built-in defined configuration document to identify the quantity and specifications of all pipes, valves, accessories and other elements in the drawing, and automatically generate the main engineering quantity table for this period, such as Figure 5 This is a schematic table of materials for interval design according to an embodiment of the present invention.

[0089] Through the above method and steps, batch drawing, batch annotation and automatic generation of engineering quantity statistics tables can be achieved, intelligent drawing is realized, and work efficiency is improved.

[0090] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
