[0002] With the diversification of domestic railway track vehicles, the variety of track vehicle products is increasing. Since track vehicle products are updated and replaced quickly, shortening the product development cycle is of great significance.

[0003] Currently, the manufacturing process for rail vehicle products is typically developed on a project-based basis. This means that staff create process documents based on the product's process parameters. However, rail vehicle products are rapidly evolving, and with each new product development, manual process documentation is required, leading to long development cycles and lower quality, with a higher error rate. Summary of the Invention

[0006] Obtain the name, lineage, and process parameters of the target rail vehicle product; where the lineage refers to the vehicle category to which the target rail vehicle product belongs.

[0007] Based on the name and lineage of the target rail vehicle product, the standard manufacturing process of the target rail vehicle product is retrieved from the pre-set manufacturing process database;

[0008] Determine whether the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product. If the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product, then the standard manufacturing process shall be used as the manufacturing process of the target rail vehicle product.

[0009] If the process parameters of the standard manufacturing process are inconsistent with the process parameters of the target rail vehicle product, the process parameters of the standard manufacturing process shall be modified according to the process parameters of the target rail vehicle product, and the modified standard manufacturing process shall be used as the manufacturing process of the target rail vehicle product.

[0010] Optionally, the design methods for rail vehicle manufacturing processes also include:

[0011] If there is no standard manufacturing process for the target rail vehicle product in the manufacturing process database, a new standard manufacturing process shall be created based on the name, lineage and process parameters of the target rail vehicle product.

[0012] Add the newly created standard manufacturing process to the manufacturing process database;

[0013] Re-examine the standard manufacturing process of the target rail vehicle product from the manufacturing process database.

[0014] Optionally, if the process parameters of the standard manufacturing process are inconsistent with the process parameters of the target rail vehicle product, after modifying the process parameters of the standard manufacturing process according to the process parameters of the target rail vehicle product and using the modified standard manufacturing process as the manufacturing process of the target rail vehicle product, the process further includes:

[0015] Update the manufacturing process database according to the revised standard manufacturing process;

[0016] The manufacturing process database is updated according to the revised standard manufacturing process, including:

[0017] Delete the existing standard manufacturing processes in the manufacturing process database and add the modified standard manufacturing processes to the manufacturing process database.

[0018] Optionally, the manufacturing process database stores standard manufacturing processes for different rail vehicle products of at least one lineage, categorized in a structured tree format. Based on the name and lineage of the target rail vehicle product, the standard manufacturing process for that product is queried from the pre-defined manufacturing process database, including:

[0019] Based on the name of the target rail vehicle product and the preset classification comparison table, determine the tree structure classification node to which the target rail vehicle product belongs;

[0020] Query the name and standard manufacturing process corresponding to the lineage of the target rail vehicle product under the classification node of the tree structure to which the target rail vehicle product belongs.

[0021] Optionally, the process of building the manufacturing process database includes:

[0022] A manufacturing process database is obtained by constructing multiple first-level nodes in a structure tree, and constructing multiple second-level nodes under each first-level node, as well as constructing standard manufacturing processes for at least one series of different rail vehicle products under each second-level node. The construction of standard manufacturing processes includes constructing process parameters for standard manufacturing processes, which include process operation parameters and process inspection parameters.

[0023] The primary nodes are the vehicle body process, painting process, assembly process, and debugging process;

[0024] The secondary nodes corresponding to the car body process are the underframe, side walls, and roof;

[0025] The secondary nodes corresponding to the coating process are functional coating, intermediate coating and topcoat;

[0026] The secondary nodes corresponding to the assembly process are the door system, electrical system, interior system, and water and steam system;

[0030] A second aspect of the present invention provides a rail vehicle manufacturing process design apparatus, comprising:

[0032] The query module is used to query the standard manufacturing process of the target rail vehicle product from a preset manufacturing process database based on the name and lineage of the target rail vehicle product.

[0033] The processing module is used to determine whether the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product. If the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product, the standard manufacturing process is adopted as the actual manufacturing process of the target rail vehicle product. If the process parameters of the standard manufacturing process are inconsistent with the process parameters of the target rail vehicle product, the process parameters of the standard manufacturing process are modified according to the process parameters of the target rail vehicle product, and the modified standard manufacturing process is adopted as the actual manufacturing process of the target rail vehicle product.

[0034] Optionally, the query module is also used for:

[0036] Add the newly created standard manufacturing process to the manufacturing process database;

[0037] Re-examine the standard manufacturing process of the target rail vehicle product from the manufacturing process database.

[0040] The beneficial effects of the embodiments of the present invention compared with the prior art are as follows:

[0041] This invention utilizes a manufacturing process database to store standard manufacturing processes for rail vehicle products. When developing a new rail vehicle product, the database is searched for the standard manufacturing process based on the product's name and lineage. It is then determined whether the standard manufacturing process matches the process parameters of the newly developed product. If they match, the standard manufacturing process is directly adopted as the actual manufacturing process for the new product. If they do not match, the standard manufacturing process is modified to suit the new product's process parameters. This invention enables the reuse of manufacturing processes, saving significant time and drastically shortening the development cycle of rail vehicle products compared to manually creating process documents.

[0049] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0050] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0051] See Figure 1 As shown, this embodiment of the invention provides a method for designing a manufacturing process for rail vehicles, which includes the following steps:

[0052] Step S101: Obtain the name, lineage, and process parameters of the target rail vehicle product; wherein, the lineage refers to the vehicle category to which the target rail vehicle product belongs.

[0053] In this embodiment of the invention, the rail vehicle is composed of many rail vehicle products. In actual production, each rail vehicle product is manufactured independently and ultimately assembled into a rail vehicle. The product lineage refers to the family of rail vehicles to which the rail vehicle product belongs, including but not limited to EMU trains, urban rail vehicles, and ordinary low-speed vehicles. Different product lines have different process parameters. Generally, once a product project is released, the process parameters of the rail vehicle products are determined, but these parameters can be modified during subsequent actual production.

[0054] Step S102: Based on the name and lineage of the target rail vehicle product, query the standard manufacturing process of the target rail vehicle product from the preset manufacturing process database.

[0055] In this embodiment of the invention, a standard manufacturing process that is identical in name and lineage to the target rail vehicle product is queried from the manufacturing process database and used as a similar process to the target rail vehicle product.

[0056] Step S103: Determine whether the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product. If the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product, then the standard manufacturing process shall be used as the actual manufacturing process of the target rail vehicle product.

[0057] In this embodiment of the invention, if the process parameters of the standard manufacturing process are consistent with the process parameters of the target rail vehicle product, the standard manufacturing process can be directly used as the actual manufacturing process of the target rail vehicle product, realizing the reuse of the manufacturing process, avoiding manual re-compilation of the process, and saving a lot of time. Furthermore, it avoids the problems of poor process document quality and high error rate caused by manually compiling manufacturing processes.

[0058] Step S104: If the process parameters of the standard manufacturing process are inconsistent with the process parameters of the target rail vehicle product, the process parameters of the standard manufacturing process shall be modified according to the process parameters of the target rail vehicle product, and the modified standard manufacturing process shall be used as the actual manufacturing process of the target rail vehicle product.

[0059] In this embodiment of the invention, since the process parameters of products of the same lineage have high similarity, the process parameters suitable for the target rail vehicle product can be obtained by modifying the standard manufacturing process, thereby realizing the reuse of the manufacturing process and saving a lot of time.

[0060] As can be seen, this embodiment of the invention stores the manufacturing processes of rail vehicle products as standard manufacturing processes in a manufacturing process database. When developing a new rail vehicle product, the standard manufacturing process is searched in the database by the product name and lineage. It is then determined whether the standard manufacturing process matches the process parameters of the newly developed product. If they match, the standard manufacturing process is directly used as the actual manufacturing process for the new product. If they do not match, the standard manufacturing process is modified to match the actual manufacturing process of the new product based on its process parameters. This embodiment of the invention achieves the reuse of manufacturing processes, saving significant time and greatly shortening the development cycle of rail vehicle products compared to manually compiling process documents.

[0061] Optionally, in one possible implementation, the method further includes:

[0062] If there is no standard manufacturing process for the target rail vehicle product in the manufacturing process database, a new standard manufacturing process shall be created based on the name, lineage and process parameters of the target rail vehicle product.

[0063] Add the newly created standard manufacturing process to the manufacturing process database;

[0064] Re-examine the standard manufacturing process of the target rail vehicle product from the manufacturing process database.

[0065] In this embodiment of the invention, if there is no standard manufacturing process in the manufacturing process database that has the same name and lineage as the target rail vehicle product, a new standard manufacturing process can be created based on the name, lineage, and process parameters of the target rail vehicle product. This new standard manufacturing process is then added to the manufacturing process database, and the search process is executed again. The new standard manufacturing process can be automatically constructed by the system based on the name, lineage, and process parameters of the target rail vehicle product, or it can be constructed by staff.

[0066] Optionally, in one possible implementation, if the process parameters of the standard manufacturing process are inconsistent with the process parameters of the target rail vehicle product, after modifying the process parameters of the standard manufacturing process according to the process parameters of the target rail vehicle product and using the modified standard manufacturing process as the actual manufacturing process of the target rail vehicle product, the method further includes:

[0067] Update the manufacturing process database according to the revised standard manufacturing process;

[0068] The manufacturing process database is updated according to the revised standard manufacturing process, including:

[0069] Delete the existing standard manufacturing processes in the manufacturing process database and add the modified standard manufacturing processes to the manufacturing process database.

[0070] In this embodiment of the invention, once a new rail vehicle product is released, the old rail vehicle product and its manufacturing process are no longer used. Therefore, replacing the old manufacturing process in the manufacturing process database with the manufacturing process of the new product can reduce the amount of data in the manufacturing process database and improve query speed.

[0071] Optionally, in one possible implementation, the manufacturing process database stores standard manufacturing processes for at least one lineage of different rail vehicle products in a structured tree format; based on the name and lineage of the target rail vehicle product, the standard manufacturing process for the target rail vehicle product is queried from the pre-defined manufacturing process database, which can be detailed as follows:

[0072] Based on the name of the target rail vehicle product and the preset classification comparison table, determine the tree structure classification node to which the target rail vehicle product belongs;

[0073] Query the name and standard manufacturing process corresponding to the lineage of the target rail vehicle product under the classification node of the tree structure to which the target rail vehicle product belongs.

[0074] In this embodiment of the invention, the manufacturing process is classified and managed through a structure tree, which improves the management level and makes it easier for staff to query the process.

[0075] Optionally, in one possible implementation, the process of building the manufacturing process database includes:

[0076] A manufacturing process database is obtained by constructing multiple first-level nodes in a structure tree, and constructing multiple second-level nodes under each first-level node, as well as constructing standard manufacturing processes for at least one series of different rail vehicle products under each second-level node. The construction of standard manufacturing processes includes constructing process parameters for standard manufacturing processes, which include process operation parameters and process inspection parameters.

[0077] The primary nodes are the vehicle body process, painting process, assembly process, and debugging process;

[0078] The secondary nodes corresponding to the car body process are the underframe, side walls, and roof;

[0079] The secondary nodes corresponding to the coating process are functional coating, intermediate coating and topcoat;

[0080] The secondary nodes corresponding to the assembly process are the door system, electrical system, interior system, and water and steam system;

[0081] The secondary nodes corresponding to the debugging process are single-vehicle testing and train testing.

[0082] In this embodiment of the invention, the structure tree is referenced. Figure 2 As shown, the first-level nodes of the structure tree are body process, painting process, assembly process, and debugging process. The second-level nodes under body process are underframe, sidewalls, and roof. Under underframe are the forward and reverse assembly processes; under sidewalls are the sidewall welding and adjustment processes; and under roof are the roof welding and roof accessory welding processes. The second-level nodes under painting process are functional coating, intermediate coating, and topcoat. Under functional coating are damping paste spraying and insulating varnish application processes; under intermediate coating are putty application and weld putty application processes; and under topcoat are topcoat spraying and color ribbon spraying processes. The second-level nodes under assembly process are door system, electrical system, interior system, and water and vapor system. Under door system are interior door process and exterior door process; under electrical system are electrical installation and wiring processes; under interior system are wall panel installation and floor installation processes; and under water and vapor system are toilet installation and sewage system installation processes. The secondary nodes under the commissioning process are single-vehicle testing and train testing. Single-vehicle testing includes assembly routine testing and monotonic routine testing, while train testing includes assembly routine testing and train commissioning routine testing. The roof, inner doors, outer doors, etc., mentioned above can all be considered rail vehicle products, and each secondary node can include manufacturing processes for multiple product lines.

[0083] In this embodiment of the invention, reference is made to Figure 3As shown, the manufacturing process parameters for each rail vehicle product are divided into process operation parameters and process inspection parameters. Process operation parameters include process content and process step content. Process process content includes: related family structure, personnel skills, process equipment (tools, fixtures, equipment), working environment, process classification, work flow, protective equipment, etc. Process step content includes step name, number of workers, work duration, work instructions, process equipment, etc. Process inspection parameters include qualitative inspection and quantitative inspection. Qualitative inspection specifies the requirements and standards for inspection, including inspection items, inspection standards, inspection modes, and inspection frequency. Quantitative inspection specifies standard values ​​and upper and lower limits, including inspection items, standard values, upper and lower limits, units, inspection modes, and inspection frequency. By integrating process operation and process inspection into a unified system, effective management of the manufacturing process can be achieved.

[0084] Optionally, in one possible implementation, after determining the actual manufacturing process of the target rail vehicle product, the following is also included:

[0085] Based on the actual manufacturing process of the target rail vehicle product, generate, display, and store the process design report of the target rail vehicle product.

[0086] Based on the above, see Figure 4 As shown, this embodiment of the invention provides a method for designing a manufacturing process for rail vehicles, including the following steps:

[0087] (1) After the product is released, obtain the product name, lineage and process parameters;

[0088] (2) Search for the standard manufacturing process of the product in the manufacturing process database;

[0089] (3) If there is no standard manufacturing process in the manufacturing process database, a new standard manufacturing process is created based on the name, lineage and process parameters. The new standard manufacturing process is added to the manufacturing process database and the standard manufacturing process is queried again.

[0090] (4) If there is a standard manufacturing process in the manufacturing process database, determine whether the standard manufacturing process is consistent with the product's process parameters. If they are consistent, directly call the standard manufacturing process as the actual manufacturing process of the product. Otherwise, modify the process parameters to obtain the actual manufacturing process of the product, and update the manufacturing process database according to the modified standard manufacturing process.

[0091] (5) Generate a process design report based on the actual manufacturing process of the product.

[0092] The rail vehicle manufacturing process design method of this invention can save a significant amount of time and greatly shorten the development cycle of rail vehicle products. Furthermore, by managing standard manufacturing processes through a structure tree approach, when constructing a standard manufacturing process, it is possible to create a name, code, process-related fields, workflow diagram, step-related fields, inspection records, etc. The code consists of 8 characters, including a 2-digit system code and a 6-digit serial number, improving the management level of standard manufacturing processes. Staff can easily query, create, and modify standard manufacturing processes during actual production, ensuring the synchronization of standard manufacturing processes with the product.

[0093] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

If the process parameters of the standard manufacturing process are inconsistent with the process parameters of the target rail vehicle product, the process parameters of the standard manufacturing process are modified according to the process parameters of the target rail vehicle product, and the modified standard manufacturing process is used as the actual manufacturing process of the target rail vehicle product.

[0103] Update the manufacturing process database according to the revised standard manufacturing process;

[0104] The manufacturing process database is updated according to the revised standard manufacturing process, which can be detailed as follows:
