Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a method and device for constructing and using a structure tree for a rail transit equipment product. Background Art

[0002] The rail transit equipment product structure tree is a hierarchical tree diagram that describes the material composition and file structure of rail transit equipment products. It combines product information in product data management with the hierarchical relationships between components to form an effective attribute management structure.

[0003] Existing rail transit equipment product structure trees are typically based on the product structure data for rail transit equipment within a specific project. Due to varying project requirements, the structures of rail transit equipment products within each project vary significantly. Consequently, the product structure trees for rail transit equipment products within each project also differ.

[0004] For example, the rail vehicles used in the Beijing Metro project utilize a three-rail power supply system, while the rail vehicles used in the Guangzhou Metro project utilize a catenary-based power supply system. This difference in power supply method results in structural differences, at least in the electrical equipment, between the rail vehicles used in these two projects. Consequently, the product structure trees for the rail vehicles in the Beijing and Guangzhou Metro projects differ, for example, in the hierarchical structure and component names within the product structure trees.

[0005] Due to the differences in the rail transit equipment product structure trees in different projects, it is difficult for technical personnel in this field to implement cross-type data processing of rail transit equipment based on the existing rail transit equipment product structure tree, such as cross-type fault analysis, which reduces the work efficiency of technical personnel.

[0050] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0051] The following combination Figure 1-Figure 7 The present invention describes the method and device for constructing and using a product structure tree for rail transit equipment.

[0052] Figure 1 The flowchart of the method for constructing the rail transit equipment product structure tree provided by the present invention is as follows: Figure 1 As shown, the method for constructing a rail transit equipment product structure tree provided by the present invention includes:

[0053] Step 101: Establish a first product structure tree of the target rail transit equipment according to the structural characteristics of the target rail transit equipment.

[0054] The target rail transit equipment refers to the rail transit equipment for which a product structure tree is to be constructed. In this invention, rail transit equipment refers to equipment related to rail transit. Typical rail transit equipment is rail vehicles. As those skilled in the art will appreciate, rail vehicles can be further categorized as EMUs (Multi-Unit Trains) operating on railways and urban rail vehicles operating on urban rail. In this embodiment, the process of constructing a product structure tree is illustrated using EMUs as an example.

[0055] The first product structure tree of the target rail transit equipment includes the structural levels of the target rail transit equipment and the names of the nodes included in each level.

[0056] The target rail transit equipment has a complex structure and can be further broken down into hierarchical components, such as systems, subsystems, equipment, and components. For example, a train-based EMU can be further divided into the following: the air conditioning and heating system (system), the driver's cab air conditioning system (subsystem), the outdoor unit (equipment), and the compressor (component).

[0057] When establishing the first product structure tree for the target rail transit equipment, you can refer to the hierarchical division of rail transit equipment. Still using the EMU as an example, when establishing the first product structure tree for the EMU, a branch is created for the air conditioning and heating system. The air conditioning and heating system branch includes a branch for the driver's cab air conditioning system, which includes a branch for the outdoor unit, and the outdoor unit branch includes a branch for the compressor. The names of the nodes at each level in the first product structure tree can be the names of the system, subsystem, equipment, or component corresponding to the level. For example, the node name can be "air conditioning and heating system," "driver's cab air conditioning system," "outdoor unit," or "compressor."

[0058] It should be noted that the first product structure tree of the target rail transit equipment is only a primary structure tree, which only includes the hierarchical relationship of the target rail transit equipment and the nodes at each level. In subsequent steps, more information can be added based on the first product structure tree.

[0059] Step 102: Associating existing product structure trees of multiple types of target rail transit equipment with the first product structure tree to obtain a second product structure tree of the target rail transit equipment.

[0060] Target rail transit equipment typically comes in multiple types. For example, a motor train may include multiple models, such as the CRH2 and CRH3. In the prior art, corresponding product structures are typically created for each of these models. In this step, these existing product structures for multiple types of target rail transit equipment are linked to the first product structure, thereby generating a second product structure for the target rail transit equipment.

[0061] The resulting second product structure tree is also called a full tree, and the association process of generating the full tree is also called full tree matching.

[0062] The structures of different types of target rail transit equipment are generally the same, but there may be differences in the shape parameters, mechanical parameters, electrical parameters, thermal parameters, etc. of specific components. Therefore, in this embodiment, by performing full tree matching on the components, the components can comprehensively cover different types of situations.

[0063] Taking EMUs as an example, when associating the existing product structure tree for multiple types of EMUs with the first product structure tree for EMUs, the EMU product structure tree can be associated using the "EMU System Function Classification Table (Yunche EMU Letter

[2016] No. 299)" issued by the China Railway Corporation. That is, based on the "EMU System Function Classification Table (Yunche EMU Letter

[2016] No. 299)," components and / or equipment in the existing product structure tree are associated with components and / or equipment in the first product structure tree that have the same name, structure, or function.

[0064] The "Function Classification Table of EMU Systems (Letter of EMU Transportation

[2016] No. 299)" is a vehicle product structure classification standard issued by the China Railway Corporation, which has normative significance for the industry.

[0065] For example, referring to the "EMU System Function Classification Table (Yunche EMU Letter

[2016] No. 299)", the CRH2 product structure tree and the CRH3 product structure tree can be associated with the first product structure tree of the EMU.

[0066] Figure 2 It is a schematic diagram of a portion of the second product structure tree of the EMU involved in one embodiment of the present invention. Figure 2 The part related to the high voltage power supply system in the second product structure tree of the EMU is described. Figure 2 The equipment and components included in the high-voltage power supply system can be seen.

[0067] It should be noted that the names in the product structure tree of existing multiple types of target rail transit equipment may be non-standard. For example, the equipment with the standard name of bogie may be named "bogie 1" on the existing CRH2 product structure tree, and may be named "bogie 2" on the existing CRH3 product structure tree, which is inconsistent with the standard name. During the association process, the data of bogie 1 and bogie 2 will be associated with the "bogie" node in the first product structure tree. Subsequently, by searching for the standard name "bogie", the content of "bogie 1" and "bogie 2" can be obtained, thereby achieving the purpose of standardizing the name.

[0068] The second product structure tree of the target rail transit equipment covers all possible structures of each type of existing target rail transit equipment in the structure tree, and keeps the structure names standardized, so that no structure is missed and the structure names are standardized and unified.

[0069] Step 103: Associating fault information with nodes in the second product structure tree that represent components of the target rail transit equipment to obtain a product structure tree for the target rail transit equipment.

[0070] During use, rail transit equipment will inevitably experience failures. These failures can be categorized as quality issues or operational issues. Quality issues refer to problems caused by the quality of the components themselves, while operational issues refer to problems caused by components not functioning as intended.

[0071] Specifically, this step may further include:

[0072] Obtain fault information of target rail transit equipment that has failed;

[0073] Classifying the fault information according to the component where the fault occurs;

[0074] According to the component where the fault occurs, the fault information is associated with a node in the second product structure tree that is used to represent the component of the target rail transit equipment.

[0075] In this embodiment, when acquiring fault information of a target rail transit equipment that has failed, it is necessary to at least acquire information on the manifestation of the fault and the component to which the fault belongs.

[0076] The manifestation of a fault is used to describe the external manifestation of the fault, such as deformation, fracture, open circuit, etc.

[0077] The fault component information is used to describe which component has failed, such as the carbon slide plate, bow head bracket, etc.

[0078] In this embodiment, in addition to the manifestation of the fault and information about the component to which the fault belongs, the fault information may also include one or more of the following information: component supplier information, fault type information (such as whether it is a quality problem or an application problem), and component usage time information.

[0079] Figure 3 This is a schematic diagram of a portion of a product structure tree associated with fault information for an EMU involved in one embodiment of the present invention. Figure 3 The association between fault information and components is realized in the system.

[0080] Those skilled in the art will readily understand that the fault information associated with the product structure tree of the target rail transit equipment includes fault information of multiple types of target rail transit equipment.

[0081] The above describes the steps of the method for constructing a product structure tree for rail transit equipment according to the present invention. This method performs full tree matching and fault information association on the product structure tree, resulting in a final product structure tree. This final product structure tree incorporates a wealth of information, enabling cross-data type queries and has broad applications in product design, fault analysis, and other areas.

[0082] Based on any of the above embodiments, in this implementation, the method further includes:

[0083] Associate the specification file with the product structure tree of the target rail transit equipment.

[0084] Normative documents refer to binding documents that rail transit equipment should comply with, such as technical standards, industry specifications, etc.

[0085] When associating a specification file, association terms are obtained from the specification file based on its content. These association terms can be the names of systems, subsystems, devices, or components within the target rail transit equipment. Based on these association terms, the corresponding nodes are then found within the product structure tree for the target rail transit equipment. Finally, the specification file is associated with the corresponding node.

[0086] During this association process, the nodes associated with the specification document need to be determined based on its scope of influence. For example, if a specification document is related to the entire rail transit equipment, then it needs to be associated with the node representing the entire rail transit equipment in the product structure tree. If a specification document is related to a specific component within the rail transit equipment, then it needs to be associated with the node representing that component. For example, the technical standards for air conditioning compressors need to be associated with the node corresponding to the air conditioning compressor in the product structure tree for rail vehicles.

[0087] Associating specification files with the product structure tree of rail transit equipment can help users quickly and easily obtain specification files.

[0088] The method for constructing a rail transit equipment product structure tree, provided by this invention, performs full tree matching, fault information association, and specification file association on the product structure tree to produce a final product structure tree. This final product structure tree incorporates a wealth of information and has broad applications in various areas, including product design and fault analysis.

[0089] Based on any of the above embodiments, Figure 4 This is a flow chart of the method for using the rail transit equipment product structure tree provided by the present invention. Figure 4 As shown, the method for using the rail transit equipment product structure tree provided by the present invention includes:

[0090] Step 401: Determine the target node corresponding to the target component in the product structure tree of the target rail transit equipment.

[0091] As mentioned in the previous embodiment, the product structure tree of the target rail transit equipment is associated with the fault information. Therefore, in this embodiment, the fault information of the target component can be analyzed based on the product structure tree of the target rail transit equipment.

[0092] A target component is a component identified by the user for analysis. For example, if a user wishes to determine the cause of a failure in an air conditioning compressor in a rail vehicle, the air conditioning compressor can be selected as the target component. The target component can be any component within the rail transit equipment. In this embodiment, there are no restrictions on the type or number of target components.

[0093] When analyzing the fault information of the target component, it is first necessary to determine the corresponding target node in the rail transit equipment product structure tree according to the target component.

[0094] For example, if the target component selected by the user is the air-conditioning compressor in the driver's cab air-conditioning system of the EMU, then according to the EMU product structure tree, the "compressor" node is found in the order of "air-conditioning and heating system - driver's cab air-conditioning system - outdoor unit - compressor".

[0095] Step 402: Obtain fault information associated with the target node.

[0096] Since the target rail transit equipment product structure tree has already associated fault information with the nodes corresponding to the components, the fault information associated with the target node can be obtained through data query.

[0097] For example, by performing a data query operation on the "compressor" node in the EMU product structure tree, the fault information of the air-conditioning compressor can be obtained.

[0098] It should be noted that since the EMU product structure tree performs full tree matching, when obtaining fault information, fault information across different vehicle models can be obtained.

[0099] For example, according to the EMU product structure tree, not only the fault information of the CRH2 model can be obtained, but also the fault information of the CRH3 model can be obtained.

[0100] Furthermore, when obtaining cross-model fault information, you can select a specific model. For example, a EMU product structure tree may contain fault data for 10 models. In practice, you may only need data for three of these models. When obtaining cross-model fault information, you can select the required three models.

[0101] The description of this step shows the advantages of performing full tree matching on the rail transit equipment product structure tree: when querying fault data, you can avoid making multiple selections in different product structure trees, avoiding duplication of work. It also avoids errors caused by different structural levels and names in individual product structure trees, as well as multiple repeated selections, thereby improving work efficiency and accuracy.

[0102] Step 403: Analyze the fault information.

[0103] As mentioned in the previous embodiments, fault information, in addition to identifying the faulty component, can also include one or more of the following: component supplier information, fault type information (e.g., whether it's a quality issue or an operational issue), and component usage history. This allows for comparative fault analysis of components of the same type from different suppliers, providing product quality indicators for different suppliers.

[0104] For example, the air conditioning compressors on rail vehicles are supplied by manufacturers A, B, and C. The supplier information included in the fault information can be used to determine the percentage of each manufacturer's product failures relative to the total number of air conditioning compressor failures. Combined with other data such as each manufacturer's market share, this provides further insight into the quality of each manufacturer's products.

[0105] Based on the fault information, the failure conditions of components at different stages of the product life cycle can also be clarified.

[0106] For example, the fault information of an air-conditioning compressor includes the length of time the air-conditioning compressor was in use when the fault occurred. Common knowledge indicates the product lifecycle of the air-conditioning compressor. By comparing the length of time the air-conditioning compressor was in use when the fault occurred with the product lifecycle of the air-conditioning compressor, we can determine the failure rate of the air-conditioning compressor at different stages of use. This provides a reference for the operation and maintenance of air conditioners in rail vehicles. For example, if the fault information analysis results show that the failure rate of the air-conditioning compressor reaches 10% when the air conditioner reaches 5,000 hours of use, rail vehicle maintenance personnel can prepare a certain number of air-conditioning compressors in advance based on the number of air conditioners that require maintenance in the near future and have reached 5,000 hours of use.

[0107] The method for using the rail transit equipment product structure tree provided by the present invention can realize cross-type query and analysis of fault information, and achieve more comprehensive understanding and analysis of fault information.

[0108] Based on any of the above embodiments, in this embodiment, the method for using the rail transit equipment product structure tree further includes:

[0109] Step S1: determining a selected component based on configuration information of a target rail transit equipment, and querying fault information of the selected component in a product structure tree of the target rail transit equipment;

[0110] Step S2: Calculate the RAMS index of the target rail transit equipment based on the fault information of the selected components;

[0111] Step S3: When the RAMS indicator of the target rail transit equipment does not meet the preset requirements, adjust the configuration information of the target rail transit equipment, and then re-execute steps S1 and S2 according to the adjusted configuration information until the RAMS indicator of the target rail transit equipment meets the preset requirements;

[0112] Step S4: output the finally determined configuration information of the target rail transit equipment.

[0113] Those skilled in the art are aware that external factors such as geographical environment, technical standards, owner requirements, and legal culture all have an impact on rail transit projects. To meet the requirements of rail transit projects, rail transit equipment is generally designed specifically for the specific rail transit project.

[0114] In this embodiment, when designing rail transit equipment, it can be implemented based on the rail transit equipment product structure tree.

[0115] When designing rail transit equipment, the project's overall planning department is typically responsible for establishing the system architecture, while the various development departments are responsible for configuring the equipment's components. The system architecture information and component configuration information obtained during the design process are collectively referred to as the rail transit equipment's configuration information. This information includes information about selected components.

[0116] The selected components are typically already used in other rail transit equipment. Therefore, based on the selected component information, fault information for the selected components can be queried within the rail transit equipment product structure tree. The details of how to query component fault information within the rail transit equipment product structure tree have been previously described in the previous examples and will not be repeated here.

[0117] The fault information of the selected components describes actual faults that have occurred in the past and therefore serves as a reference for designers.

[0118] Based on the displayed fault information of the selected components, designers can implement technical circumvention to prevent similar faults from recurring in newly designed rail transit equipment. Specifically, in this embodiment, the RAMS index of the rail transit equipment can be calculated based on the fault information of the selected components.

[0119] RAMS is an abbreviation for Reliability, Availability, Maintainability, and Safety, and is defined as reliability, availability, maintainability, and safety. Reliability refers to a product's ability to perform its specified function under specified conditions and within a specified timeframe. Availability refers to the degree to which a product is operational or usable when required and begins to perform its task at any random moment. Maintainability refers to the ability of a product to maintain or restore its specified condition when repaired according to specified procedures and methods under specified conditions and within a specified timeframe. Safety refers to the product's ability to avoid causing loss of life, damage to systems, significant property loss, or harm to employee health or the environment.

[0120] How to calculate the RAMS index of rail transit equipment based on the fault information of selected components is common knowledge to those skilled in the art, and therefore will not be repeated here.

[0121] RAMS indicators guide design. If the RAMS indicators corresponding to the current configuration information of rail transit equipment cannot meet the preset requirements, the configuration information of the rail transit equipment needs to be adjusted. Then, based on the adjusted configuration information, the fault information of the selected components is re-queried in the rail transit equipment product structure tree, and the RAMS indicators are recalculated based on the newly obtained fault information. The newly obtained RAMS indicators are then compared with the preset requirements. If they are still not met, the process of adjusting the configuration information, querying the fault information, calculating the RAMS indicators, and comparing the RAMS indicators is repeated until the preset requirements are met.

[0122] After the configuration information of the rail transit equipment is determined according to the RAMS index of the rail transit equipment, an FMECA analysis report can be generated based on the data generated in the process of calculating the RAMS index and the configuration information finally obtained.

[0123] FMECA is the abbreviation of Failure Mode, Effects and Criticality Analysis, which is defined as: failure mode, effects and criticality analysis and reporting.

[0124] How to generate an FMECA analysis report is common knowledge to those skilled in the art and will not be repeated here.
