Description

Technical Field

[0001] The present invention belongs to the technical field of subway station building design methods and systems, and specifically relates to an intelligent design method for a rail transit station building scheme. Background Art

[0002] The existing technology requires a lot of manpower and energy to design station building plans because of the complexity of the building plan design, multiple interfaces, and a large number of repetitions in the process. Designers need to consider the funding factors of various internal and external units (various professions) in the process of completing the architectural design plan in AutoCAD format. The external consideration is mainly to consider that the general layout of the rail transit station building must match the urban planning and surrounding plots, and the internal consideration is mainly to consider that the overall scale of the rail transit station and the layout of the public area, equipment area, etc. must meet the needs of various professions and passengers.

[0003] However, rail transit stations involve more than 30 disciplines, each of which has its own specific technical requirements. Designers need to make a comprehensive consideration and arrange a draft of the architectural plan metafile in AutoCAD format, and then feedback to each discipline for confirmation and modification one by one. During the modification process, they also need to constantly cooperate with related disciplines. This process is time-consuming and labor-intensive. At the same time, the modification of one discipline often affects other disciplines. Designers often find it difficult to coordinate in a short period of time to ensure that all internal and external units (disciplines) have no objections. Usually, this process takes 1 to 2 months, and finally forms an architectural plan that meets the needs of various internal and external funding factors and meets the various technical specifications currently in force in the country for rail transit design.

[0004] From this, it can be seen that the existing station building design model consumes a lot of manpower and energy, has a huge amount of repetitions and is inefficient. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide an intelligent design method for rail transit station building plans, which can effectively solve the shortcomings of manpower, energy and technology in the design of existing single-line ordinary station building plans, greatly reduce repetitive and ineffective work in the process, and greatly improve work efficiency.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A method for intelligently designing a rail transit station building scheme comprises the following steps:

[0008] S10: Collect and input internal and external information;

[0009] S20: Integrate internal and external data and convert them into algorithm script files as overall technical requirements;

[0010] S30: Based on the algorithm script file, the BIM software system automatically generates the public area plane unit module and constructs the equipment area plane module, coordinates and splices the public area plane unit module and the equipment area plane module, and designs the import and export modules and wind pavilion modules at the same time to generate the first draft of the station building plan;

[0011] S40: After the draft station building plan is generated, a compliance check is carried out to review the requirements of various internal and external technical specifications one by one to verify whether they can meet the requirements; if there are parts of the draft station building plan that fail to meet the requirements, the unsatisfactory parts are iteratively modified and automatically reviewed again after modification until a station building plan that meets the requirements of various internal and external technical specifications is generated.

[0012] The present invention has the following beneficial effects:

[0013] The present invention is mainly aimed at the design of single-line ordinary stations. Through the BIM software system technology, the basic technical data of various internal and external units or professions are integrated, and an algorithm script file is formed after AI technology processing. The BIM software system automatically generates a public area plane unit module according to the algorithm script file, and constructs an equipment area plane module, and the public area plane unit module and the equipment area plane module are spliced ​​together, and the import and export modules and the wind pavilion modules are designed at the same time to generate a preliminary draft station building plan. Since the preliminary draft plan generated by the BIM software system sometimes has local errors, the BIM software system is also required to review and inspect the equipment area plane module. When there are local errors during verification, the BIM software system can iteratively modify the incorrect part, and can re-verify after modification until a station building plan that meets the requirements of various internal and external technical specifications is generated. Compared with the existing technology, designers need to comprehensively consider various internal and external funding factors, and after multiple rounds of repeated integration and modification, the required car shock building plan is formed. The intelligent design method for rail transit station building scheme of the present invention can effectively solve the shortage of manpower, energy and technology in the design of existing single-line ordinary station building schemes, greatly reduce the repeated and ineffective work in the process, and greatly improve work efficiency.

[0020] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0021] The present invention is mainly aimed at the design of single-line ordinary stations. Based on BIM technology, the basic technologies of various internal and external units (various disciplines) are integrated. In the process, the scheme is iteratively corrected through automatic BIM re-inspection, and the optimal station construction scheme is finally generated. The architectural drawings are automatically generated through the BIM-based automatic drawing program. This method is time-saving and does not require a large amount of manpower. The station construction scheme automatically iterated based on BIM is also relatively optimal.

[0022] The intelligent design method for the rail transit station building scheme of the present invention is introduced in detail below:

[0023] like Figures 1 to 6 As shown, a method for intelligent design of rail transit station building scheme includes the following steps:

[0024] S10: Collect and input internal and external data; among which, external data mainly include surrounding terrain, road red lines, surrounding land use nature, current national rail transit station design specifications, etc. Internal data mainly include technical requirements of various professional electromechanical for civil engineering (such as ventilation and air conditioning, water supply and drainage, power lighting, automatic ticket vending and checking, integrated monitoring, lines, tracks, limits, civil air defense, AFC, FAS, BAS, gas extinguishing, communication, signal, power supply, security, escalator, shielding door, etc.), overall technical requirements, etc.

[0025] S20: Integrate internal and external data and convert them into algorithm script files as the overall technical requirements. Among them, the conversion of algorithm script files mainly depends on the content of internal and external data, the target programming language, and relevant architectural design standards. Therefore, when integrating internal and external data and converting them into algorithm script files, AI tools can be used to automatically generate and convert them into relevant algorithm script files in the following ways: ① Determine goals and needs, that is, according to the relevant requirements of internal and external data, automatically form a station building plan that meets the requirements; ② Data collation and analysis, that is, analyze internal and external data to sort out the relevant logic of internal and external data to ensure that they can be clearly mapped to the algorithm; ③ Write algorithm scripts, that is, process input data or parameters by writing code, and according to the designed algorithm, gradually write code to implement the core logic, and then write code to process and format the output results.

[0026] When integrating internal and external data and converting them into algorithm script files, the following methods are used for external data and internal data respectively:

[0027] S21: Regarding external data: The external data is parameterized through AI tools, converted into a master plan algorithm script file and entered into the BIM software system for the quantitative constraints of the master plan for the station layout.

[0028] S22: Regarding internal data: collect and integrate internal data, use the BIM software system to extract the control factors of the internal data, and then use AI tools to parametrically process the extracted control factors, convert them into plane algorithm script files and enter them into the BIM software system for the plane quantitative constraints of the station layout. The control factors will be determined according to the requirements of the relevant equipment functions of the internal data of the station to be built, so there will be multiple control factors.

[0029] S30: Based on the algorithm script file in S20, the BIM software system automatically generates the public area plane unit module, constructs the equipment area plane module, and coordinates the public area plane unit module and the equipment area plane module. At the same time, the import and export modules and the wind pavilion module are designed to generate the first draft of the station building plan. The process adopts the following methods:

[0030] Among them, Figures 1 to 4 As shown in the figure, in the process of generating the public area plane unit module, designing the import and export module and the wind pavilion module, the following methods are adopted:

[0031] S31: Based on the overall technical requirements document and the overall issued public area plan general drawing file (the public area plan general drawing file is an Autodesk two-dimensional file), the BIM software system can obtain the length and width dimensions of the station and the public area layout drawing, convert the public area layout drawing into a script file, and form a public area plan unit module, which is then entered into the BIM software system.

[0032] S32: The BIM software system obtains the inlet and outlet dimensions and inlet and outlet layout principles according to the requirements of the "Metro Design Code", the quantitative constraints of the general plan and the quantitative constraints of the plane, and then designs and arranges the corresponding number of inlets and outlets to form an inlet and outlet module.

[0033] For example, when carrying out the layout of the entrances and exits of the general plan, first of all, according to the "Metro Design Code" GB 50157-2013, the general plan quantitative constraints and the plane quantitative constraints, the station's peripheral dimension information and the entrance and exit layout principles can be obtained. Regarding the entrance and exit layout principles: one entrance and exit is set in each quadrant, a total of four, and the entrance and exit lifting height is obtained based on the input data of the line professional and the ground terrain elevation. If the lifting height is greater than 10 meters, the entrance and exit is considered to be arranged in the form of 6.5 meters wide two handrails and one ladder. If the lifting height is less than 10 meters, the entrance and exit is considered to be arranged in the form of 5 meters wide one handrail and one ladder. At the same time, the entrance and exit are set 3 meters back from the outer frame (back red line) of the overall technical requirements quantitative constraints according to the requirements of the overall technical requirements quantitative constraints, and the spacing requirements of the surrounding buildings and structures meet the "Code for Fire Protection Design of Buildings" GB50016-2018. Generally speaking, for civil buildings with first and second level fire resistance, the fire separation distance should be no less than 6 meters; for high-rise buildings, the fire separation distance should be no less than 13 meters; and for the fire separation distance between high-rise residential buildings and multi-story residential buildings, it should be no less than 9 meters. At the same time, the civil defense section of the entrance and exit sets the main entrance and exit in wartime diagonally according to the input data of the civil defense system, that is, two civil defense doors are set in the passage, and the remaining two entrances and exits are blocked in wartime, and only one civil defense door is set in the passage. The BIM software system automatically arranges the entrances and exits of the general plan according to the terrain, red lines, and site elevation conditions in the system and combines the above quantitative constraints, and forms the entrance and exit sub-module of the general plan.

[0034] S33: The BIM software system obtains the number and layout principles of wind shelters according to the requirements of the "Metro Design Code", the quantitative constraints of the general plan and the quantitative constraints of the plane, and then designs and arranges the corresponding number of wind shelters to form a wind shelter module.

[0035] For example, when carrying out the layout of the general plan wind pavilion, according to the "Metro Design Code" GB 50157-2013, the general plan quantitative constraints and the plane quantitative constraints, the wind pavilion is arranged in two groups, one group is arranged at the large and small ends, and each group is arranged with four air outlets, namely two piston air outlets, one exhaust outlet, and one fresh air outlet. The area of ​​each piston air outlet is about 20㎡, and the fresh air outlet and exhaust outlet are about 15㎡. The edge of the air outlet is set 3 meters away from the outer frame (red line) of the overall technical requirements quantitative constraints according to the requirements of the overall technical requirements quantitative constraints. At the same time, according to the standard environmental impact assessment distance, the air outlet must be more than 15m away from the surrounding buildings and structures, and more than 20m away from sensitive buildings. The BIM software system automatically arranges the general plan wind pavilion according to the terrain conditions and combined with the above quantitative constraints, and forms the general plan wind pavilion module.

[0036] After S33, the general map of the station can be regularized to obtain the general map file of the station building plan. The process adopts the following method: the BIM software system combines and regularizes the length and width of the station of S31, the import and export modules of S32 and the wind shelter module of S33 to form a station general map module, and uses the BIM software system to convert the format of the station general map module to export the CAD format file. At the same time, the annotation plug-in provided by the system is used to annotate the CAD format file of the station general map module according to the "General Map Drawing Standard" GB / T50103-2001, thereby forming a station building plan general map file, which is an Autodesk two-dimensional file.

[0037] It is known that according to the plane quantitative constraints of internal data, the subway station structure is usually roughly divided into the station hall layer and the platform layer, and the station hall layer and the platform layer have corresponding public areas and equipment areas, so the station hall layer and the platform layer can also be divided into the station hall layer public area, the station hall layer equipment area, the platform layer public area, and the platform layer equipment area. Based on this, in the process of constructing the equipment area plane module, the following method is adopted:

[0038] S34: Figures 1 to 6 As shown, the BIM software system constructs the hall layer plane and platform layer plane respectively at the hall layer and platform layer of the subway structure according to the plane quantitative constraints, and then forms different sub-unit modules with the rooms of required functions of each profession according to the general plan quantitative constraints and the plane quantitative constraints. At the same time, multiple control constraint parameter attributes are added to the sub-unit modules according to the corresponding professions. Multiple sub-unit modules are set on the hall layer plane as hall layer equipment area modules, or are set on the platform layer plane as platform layer equipment area modules according to the plane quantitative constraints. The hall layer equipment area module and the platform layer equipment area module constitute the equipment area plane module.

[0039] Among them, the control constraint parameter attributes can be geometric size height, plane position, setting principle, use requirements, personnel usage, etc. Here is an example: For example, the specific technical requirements control constraints (control constraint parameter attributes) of the power lighting major are refined as follows: the equipment area of ​​each floor of the station should have a lighting distribution room for each fire partition; the effective area of ​​the lighting distribution room in the equipment area is about 20m2, which is determined by each station based on the actual number of equipment; EPS is installed in all lighting distribution rooms in the equipment area, and the depth of the room should not be less than 3.2m; the height of the room after decoration is not less than 3.5m, and two 1.2m wide fire doors are required if the length is greater than 7 meters. The room is usually considered unused, and ventilation needs to be considered.

[0040] In S34, when multiple sub-unit modules are set on the station hall plane or platform plane according to the plane quantitative constraint conditions, the following conditions must be followed: that is, according to the multiple sub-unit modules generated in S34, a corresponding plane plan is formed after one by one comparison according to the control constraint parameter attributes, specifically:

[0041] 1) Make it clear whether the rooms required for each specialty are occupied by personnel. If so, the sub-unit module is arranged in the large end of the station hall floor plan where there are people; if not, the sub-unit module is arranged in the small end of the station hall floor plan where there are no people.

[0042] 2) Clarify the geographical location and setting principles of each sub-unit module. For example, first clarify the large partition where each sub-unit module is located. For example, if the partition is in the equipment area, then according to the equipment room layout principle, the equipment room is divided into three zones with the aisle as the boundary, of which the two aisles are between the two aisles, the outside of the main aisle is the first zone, and the outside of the secondary aisle is the third zone; Zone 1 is for the strong and weak current rooms that require 24-hour air conditioning; Zone 2 is for the remaining rooms that require 24-hour air conditioning and rooms that need ventilation. The rooms that need ventilation should be as close to the environmental control room as possible; Zone 3 is for rooms that need ventilation and non-24-hour management rooms. Each sub-unit module is then placed in a specific small partition according to the above principles.

[0043] 3) Clarify the use requirements of each sub-unit module and whether there are any joint effects between them. For example, the station control room, stationmaster's room, integrated monitoring equipment room, and communication equipment room are arranged adjacent to each other, and the rooms of the relevant integrated monitoring system need to be arranged in one area; water rooms including toilets, cleaning tool rooms, and drinking water rooms are arranged centrally, and toilets should be arranged on the upper and lower levels of the station hall and platform, and share the sewage pump room. According to the specific use requirements of each sub-unit module, determine the specific sub-division of the large partition module where the sub-unit module is located.

[0044] 4) Clarify the height, size, number of door openings and direction of each sub-unit module so that the BIM software system can perform automated design based on the above constraints.

[0045] After S34, the station master map module is superimposed on the station hall plane, with the effective platform as the base point for reference. After superposition, the BIM software system improves or adjusts the layout of the wind shelter module in the station hall plane according to the plane quantitative constraints, so that the layout of the wind shelter module meets the requirements of external and internal data.

[0046] S35: After completing step S34, further determine whether there is excess space in the equipment area module of the hall layer and / or the equipment area module of the platform layer. If so, set a spare module in the excess space to form the final equipment area plane module; if not, proceed to the next step. Among them, the spare module is also a kind of sub-unit module, also called a "room / spare room" sub-unit module. Therefore, by setting a spare module in the excess space, the spare module can be used for replacement or conversion during the design process, thereby improving the design efficiency.

[0047] S36: The BIM software system coordinates and splices the public plane unit module of S31 and the equipment area plane module of S35 to form a station layered plane module; then the height of each sub-unit module is obtained according to S34 to generate a station section module using the BIM software system; the station layered plane module and the station section module constitute the preliminary draft of the station building plan.

[0048] S40: After the draft station building plan is generated, a compliance check is carried out to review the requirements of various internal and external technical specifications one by one to verify whether they can meet the requirements; if there are parts of the draft station building plan that fail to meet the requirements, the unsatisfactory parts are iteratively modified and automatically reviewed again after modification until a station building plan that meets the requirements of various internal and external technical specifications is generated.

[0049] In the process of compliance checking the draft station building plan and iteratively modifying it when the requirements are not met, the following method is adopted: according to the station layered plane module of S36, the station layered plane module is fed back to the BIM software system, and then the control constraint parameter attributes of the station layered plane module and each sub-unit module in S34 are reviewed one by one using the review algorithm analysis plug-in of the BIM software system. If all of them are satisfied, the BIM software system automatically exports the drawing files of the station layered plane module and the station section module in the corresponding format. If the control constraint parameter attributes of individual sub-unit modules are not satisfied, the BIM software system automatically repeats step S34 to iteratively modify the control constraint parameter attributes of individual sub-unit modules until the station layered plane module and the station section module that meet the control constraint parameter attributes of each sub-unit module are generated.

[0050] Among them, the method for iterative modification for the situation where the control constraint parameter attributes of individual sub-unit modules are not satisfied is that, under the premise that other sub-unit modules are not changed, the individual sub-unit modules are modified separately, and then the steps S34 to S40 are repeated cyclically until the generated station layered plane module and station section module can satisfy the control constraint parameter attributes of all sub-unit modules. This iterative modification can realize the function of targeted modification, which has the advantage of improving design efficiency and accuracy.

[0051] S50: The BIM software system exports the CAD format drawing files of the station layered plane module and the station section module of S40, and based on the system automatic annotation plug-in, automatically annotates the two-dimensional dimensions of the CAD format drawing files of the station layered plane module and the station section module according to the "Architectural Drawing Standard" GB / T50104-2010; during automatic annotation, the length, width, area and other parameters of the rooms and public areas corresponding to each sub-unit module of the station layered plane module can be annotated according to the "Architectural Drawing Standard", the elevation of the station section module can be annotated, the orientation and length and width of the import and export modules can be annotated, the orientation and length and width of the wind shelter module can be annotated, etc.; thereby, the layered plane and section drawing files of the station building plan are finally formed, and at the same time, combined with the station building plan general drawing file formed after S33, a final complete set of building drawing plans are formed.

[0052] In summary, the present invention is mainly aimed at the design of a single-line ordinary station. Through the BIM software system technology, the basic technical data of various internal and external units or professions are integrated, and an algorithm script file is formed after being processed by AI technology. The BIM software system automatically generates a public area plane unit module according to the algorithm script file, and constructs an equipment area plane module, and the public area plane unit module and the equipment area plane module are spliced ​​together, and the import and export modules and the wind pavilion modules are designed at the same time to generate a preliminary station building plan. Since the preliminary plan generated by the BIM software system sometimes has local errors, the BIM software system is also required to review and inspect the equipment area plane module. When there are local errors during the verification, the BIM software system can iteratively modify the incorrect part, and can re-verify after the modification until a station building plan that meets the requirements of various internal and external technical specifications is generated. Compared with the existing technology, designers need to comprehensively consider various internal and external funding factors, and after multiple rounds of repeated integration and modification, the required car shock building plan is formed. The intelligent design method for rail transit station building scheme of the present invention can effectively solve the shortage of manpower, energy and technology in the design of existing single-line ordinary station building schemes, greatly reduce the repeated and ineffective work in the process, and greatly improve work efficiency.
