[0047] S0: Receive platform door engineering data for various vehicle models.

[0048] When receiving platform door engineering data of various vehicle models, it is necessary to ensure that all data are received; currently, the train models in the urban rail transit field mainly include A, B, C, D, L and other models; for different vehicle models, the collection of existing platform door engineering data should meet the requirements of completeness and comprehensiveness. Therefore, in the process of collecting and counting platform door engineering data, all platform door engineering data corresponding to the above-mentioned A, B, C, D, L and other vehicle models should be considered.

[0049] S1: Determine the modeling methods and modeling parameters of platform door models for various vehicle types based on platform door engineering data, including:

[0050] First, determine the door type, infrastructure and ancillary equipment of the platform door models of various types; then, determine the modeling method and modeling parameters of the door type, infrastructure and ancillary equipment based on the platform door engineering data; the modeling method is to establish the door type, infrastructure, and ancillary equipment according to the platform door system parameters in a way that requires the least modeling parameters and is the most convenient modeling method.

[0051] Table 1 shows the existing platform door engineering data that should be collected, as follows:

[0052]

[0053]

[0054] Platform door engineering data should include:

[0055] The relevant engineering data received are input data from staff, including the number of train sections, number of doors on each side, distance between doors, parking accuracy, door form, platform clearance height, track area wind pressure, driving mode (fully automatic / non-fully automatic), operation mode (fast / slow line operation), and insulation scheme required by the project;

[0056] Among the system parameters, the size, location, and glass thickness of the platform door system.

[0057] Among the door types, the number, height, limits of various types of sliding doors / non-standard sliding doors, fixed doors / non-standard fixed doors, and emergency doors, and the number, size, and form of end doors.

[0060] See also Figure 2 As shown, Figure 2The figure is a schematic diagram of the input interface of the interactive program in the present invention, specifically, taking the 8A marshaling full-height enclosed platform screen door as an example, it is an interface for partial data input in the modeling software; the technician can drive the BIM model software to automatically establish the platform door BIM model by selecting the train type, platform door type, etc. on the interactive program, and inputting the constant active parameters of the platform door BIM model to be generated. By parameterizing the interactive program, the amount of parameters input by the technician when generating the platform door BIM model can be reduced, the probability of human error can be reduced, and the design efficiency of the platform door BIM model can be improved and the design time can be reduced.

[0061] S2: Divide the modeling parameters into basic parameters and constant-variable parameters, wherein the parameters whose modeling parameters do not change with the engineering changes are determined as basic parameters; the parameters whose modeling parameters change with the engineering changes are determined as constant-variable parameters; the constant-variable parameters are determined according to the basic parameters; taking the BIM model software drawing as an example, see Table 1, including the optimal modeling methods of various door bodies, infrastructure and auxiliary equipment in the platform door BIM model, and the modeling parameters used in their respective modeling processes; taking the door body type as an example, how to divide the modeling parameters into basic parameters and constant-variable parameters is explained:

[0062] The door body types such as sliding doors / non-standard sliding doors, fixed doors / non-standard fixed doors, emergency doors, and end doors are determined based on the input data of technicians. In actual design, the door body type will not change according to the engineering data, so these parameters are classified as basic parameters; after determining the door body type, that is, after determining what door body is needed, it is necessary to determine the door body data based on the determined door body type, that is, the number of sliding doors / non-standard sliding doors, fixed doors / non-standard fixed doors, dimensions, limits and other data are determined based on the basic parameters, and these data will change according to the engineering data, so the number of sliding doors / non-standard sliding doors, fixed doors / non-standard fixed doors, dimensions, limits and other data are classified as constant variable parameters.

[0063] S3: According to the logical relationship between the constant changing parameters, the constant changing parameters are divided into constant changing active parameters and constant changing driving parameters; wherein the logical relationship is whether the constant changing parameters are affected by other constant changing parameters, and the constant changing parameters that are not affected by other constant changing parameters are determined as constant changing active parameters, and the constant changing parameters that are affected by other constant changing parameters are determined as constant changing driving parameters.

[0064] Table 2 shows the constant active parameters and constant driving parameters in the constant parameters of the platform door model, as shown below:

[0065]

[0066] The following describes how to divide the constant-variable parameters into constant-variable active parameters and constant-variable driving parameters:

[0067] The train model (number of train sections, number of doors on each side, door spacing, parking accuracy), engineering requirements, and platform door total height and length are not affected by other parameters and are set during the design. Therefore, these parameters are determined as constant active parameters, that is, parameters that need to be input by technicians.

[0068] The number of sliding doors, the dimensions between sliding doors, the number of fixed doors, the dimensions between fixed doors, the number of embedded parts, the distance from the embedded parts to the effective platform centerline, the number of columns, the dimensions between columns, the number of door drive motors, the installation position distance, etc.; the door body form, platform clearance height, glass thickness, insulation scheme, the number and dimensions of emergency doors, gap detection scheme, and the limits of each component; the size and number of top boxes, the size of basic columns; the width of non-standard sliding doors, the width of non-standard fixed doors; the size of door sills and anti-stepping rubber strips, etc.; the above parameters will be affected by other parameters and can be automatically set according to the setting of the constant variable active parameters, so these parameters are determined as constant variable drive parameters.

[0070] The programming language is determined according to the modeling method, basic parameters, constantly changing active parameters, constantly changing driving parameters and logical relationships; the modeling method and basic parameters are determined as the default data of the interactive program, that is, the technical personnel do not need to determine the modeling method and modeling parameters; the constantly changing active parameters are determined as the input data of the interactive program; the constantly changing driving parameters are automatically assigned according to the constantly changing active parameters and logical relationships, and the constantly changing driving parameters are determined as the driving data of the interactive program, that is, this part of data is automatically filled in according to the parameters input by the technical personnel; the programming language is used to develop the interactive program, and the platform door BIM model is constructed through the interactive program; a drawing software reference is added to the programming language, and the drawing software is used to establish a connection between the interactive program and the BIM model software.

[0071] This interactive program is applicable to the parametric drive design method of platform door BIM model for various types of vehicles. According to the modeling method, basic parameters, constant active parameters, constant drive parameters and related logical relationships of the platform door BIM model, a suitable programming language is selected to design and build a parametric drive interactive program with a friendly interface, simple operation and clear functions, so as to realize operations such as parameter input and verification, connection of BIM model software, automatic generation, saving and modification of the model.

[0072] Taking the VB.NET programming language development in Visual Studio as an example, add a drawing software reference (such as Figure 3As shown in the figure, the drawing software is controlled by the main programming language of the drawing software, which is suitable for the BIM model parameterized driving interactive program of platform doors of various types (such as Figure 2 As shown in the figure, the program interactive interface provides functions such as constant active parameter input, parameter data viewing, and correction of the platform door model, which is convenient for technical personnel to input and check data. Finally, the program will automatically connect and control the drawing software to realize automatic generation, saving, and modification of the platform door BIM model.

[0073] By taking the constantly changing active parameters as input parameters and reducing the parameter input for constructing the platform door BIM model, human errors can be reduced and the design requirements of various vehicle models can be met, thereby improving the model design efficiency, enhancing the model design accuracy and shortening the model design cycle.

By constructing a platform door model library including BIM models of platform doors for various types of vehicles, the standardization and modularization of platform door design can be achieved, and the design efficiency and accuracy can be improved. At the same time, it is convenient to quickly call and modify platform door models of different types of vehicles, thereby shortening the design cycle, reducing design costs, and ensuring the consistency and reliability of the design.

[0075] See also Figure 3 As shown, a BIM software (drawing software) reference is added to the programming language to establish a connection between the interactive program and the BIM software, so that the BIM model software can be driven by the interactive program to achieve the establishment of BIM models of platform doors for various types of vehicles.

[0076] See also Figure 4 As shown, the design method is further explained in combination with the specific implementation process, as follows:

[0078] The modeling parameters are divided into basic parameters and constant-variable parameters according to whether they often change with the engineering needs. The modeling parameters that do not often change with the engineering needs are determined as basic parameters, and the modeling parameters that often change with the engineering needs and the parameters determined based on the basic parameters are determined as constant-variable parameters.

[0079] Analyze the logical relationship between the constant-variable parameters of the platform door models of various vehicle models, and divide the constant-variable parameters into constant-variable active parameters and constant-variable driving parameters according to whether they change only when other constant-variable parameters change. Determine the constant-variable parameters that do not change only when other constant-variable parameters change as constant-variable driving parameters, and determine the constant-variable parameters that change only when other constant-variable parameters change as constant-variable active parameters.

When constructing the platform door BIM model, you only need to input constantly changing active parameters to drive the BIM model software to automatically build the platform door BIM model.
