Description

Technical Field

[0001] The present invention relates to the field of environmental protection technology for rail transit vehicles, and in particular to a management system and method for rail transit vehicle products. Background Art

[0002] With the tightening of environmental protection control and the increase in export projects, rail transit vehicle manufacturers need to deal with more and more environmental protection-related technical trade barriers. Taking the export to the EU as an example, the environmental protection regulations and directives involved in rail transit vehicles include REACH Regulation (Registration, Evaluation, Authorization and Restriction of Chemicals), CLP Regulation (Classification, Labeling and Packaging of Substances and Mixtures), POPs Regulation (Regulation on Persistent Organic Pollutants), ODS Regulation (Prohibition of Ozone Depleting Substances), F-Gas Regulation (Fluorinated Greenhouse Gas Regulation), WFD Directive (Waste Framework Directive), RoHS Directive (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment), Battery Directive, Packaging Directive, and the Railway Industry Substance List (RISL) issued by the European Railway Industry Association (UNIFE). These regulations and directives are characterized by multiple control requirements, complex content, different scopes of control (such as product applications or materials) for each regulation and directive, and some regulations and directives also require obligations to be fulfilled.

[0003] Taking REACH regulation as an example, all parts and materials on rail transit vehicles are subject to regulatory control, and the main regulatory obligations involved include registration, notification, notification and restriction.

[0004] Restriction obligations: Rail transit vehicles must meet the requirements of Annex XVII (restricted substances clauses) of the REACH Regulation. It is worth noting that each substance in Annex XVII specifies the scope of control and is not completely applicable to rail transit vehicles. Applicable clauses must be identified one by one;

[0005] Obligation to inform: When rail transit vehicles contain substances of very high concern (SVHC) and the content exceeds 0.1%, information needs to be transmitted;

[0006] Notification obligation: When the SVHC content in rail transit vehicles exceeds 0.1% and the total amount exceeds 1 ton / year, in addition to the notification obligation, it is also necessary to notify the European Chemicals Agency (ECHA);

[0007] Registration obligation: When rail transit vehicles contain "intentionally released substances" and the amount exceeds 1 ton / year, they need to be registered with ECHA.

[0008] At present, the OEMs mainly take the following measures for environmental protection control of rail transit vehicles: First, the OEMs formulate control implementation rules and issue them to suppliers. The implementation rules clarify the banned and restricted substances in rail transit products. Suppliers provide test reports or declaration documents to the OEMs for review according to the requirements of the implementation rules. The existing control methods mainly have the following problems:

[0009] The control requirements of regulatory directives in the implementation rules are not updated in a timely manner.

[0010] Suppliers are not clear about which items should be tested for their materials. If a component contains multiple materials, it is necessary to first determine the material type and then select the items to be tested based on the scope of regulatory control.

[0011] Suppliers are unclear about how to implement control requirements. For example, complex components may contain hundreds of parts and dozens of materials. It is not appropriate to test each material one by one from the perspective of economy and time.

[0012] It takes a long time for technicians to review test reports. For components that contain multiple materials, it is necessary to ensure that each material in the component BOM (bill of materials) meets the requirements before the component can be deemed compliant. Technicians need to match the test report with the materials in the BOM one by one. If multiple parts use the same material, technicians need to verify whether the information is complete one by one based on the same material declaration provided by the supplier.

[0013] When reviewing reports, abnormal data (such as SVHC, intentionally released substances, etc.) need to be manually summarized and counted. Since REACH regulations stipulate that there is a reporting obligation when SVHC exceeds 0.1% and the total amount exceeds 1 ton / year, it is necessary to count each SVHC (currently there are 219 SVHC substances) with a content exceeding 0.1% in all components, and obtain the total SVHC by multiplying the SVHC content by the weight of its parts, and then combine the annual export volume to determine whether the threshold of the reporting obligation (1 ton / year) is reached. This process requires manual statistics, which is very time-consuming and prone to errors.

[0014] Suppliers have a large number of test reports and declarations. The existing archiving method is to classify and archive them by system-subsystem-component. It is extremely inconvenient to specifically query the test report or declaration of a certain material under a component.

[0015] Some industries have developed system platforms for product environmental management and control, such as the leading GDX (Green Data Exchange) green data exchange system platform in the electronics and electrical industry. Suppliers use the GDX system to upload material information of components and materials. Electrical manufacturers can check component compliance information through the built-in regulatory information in the GDX system, complete the summary of all material information of the whole product and generate a product compliance report. Similar to this is the IMDS (International Materials Data System) international automotive material data system in the automotive industry. Suppliers use the system to declare the constituent substances of each material in the product, namely the material data sheet (MDS). The OEM reviews the MDS and checks whether it complies with regulatory requirements through the built-in regulatory information in the system.

[0016] For the rail transit industry, the common problems of these systems are:

[0017] The system determines compliance by judging whether the material composition of the material is a controlled substance under regulation and whether the material content is within the limit. However, the rail transit industry currently lacks a supply chain material information transmission mechanism, and there are many types of materials on rail transit vehicles. Most suppliers are unable to provide material composition information for all materials, especially parts assembly companies. On the other hand, the presence of some harmful substances is not intentional, but is introduced due to process pollution or as a by-product of processing. In short, suppliers are unable to provide more accurate and comprehensive material composition information.

[0018] At present, environmental protection control in the rail transit industry is still mainly based on testing. Since different regulations have different application scopes and different controlled substances target different materials, there may be differences in the testing items for different materials. These systems cannot identify the test items for different materials and compare the test results with the limits of the controlled substances in the regulations to determine whether they are qualified or not. These systems can only identify whether the material composition reported by the supplier contains SVHC, but cannot count the total amount of each SVHC in the final product, and cannot quickly know whether the product has a notification obligation. These systems do not have the function of counting the total amount of intentionally released substances in the product, and cannot quickly know whether the product has a registration obligation. Summary of the invention

[0019] The present invention provides a management system and method for rail transit vehicle products. Through the process management of environmental protection control planning, formulation of implementation plans, declaration and review of material information and environmental protection data, and data analysis, real-time monitoring of the green compliance of rail transit vehicle products and identification of risks and regulatory obligations are achieved, thereby improving work efficiency.

[0020] The embodiment of the present invention provides a management system for rail transit vehicle products, including: a BOM management module, which is used to import the BOM structure of the rail transit vehicle and send the BOM of each component to the corresponding first party;

[0021] Basic database module, used to preset the correspondence between material categories and compliance documents;

[0022] The regulatory standards management module is used to structure the data of regulatory standards control requirements and obtain structured data corresponding to material control requirements and material categories;

[0023] Declaration module, used for material data information declaration and compliance document declaration;

[0024] The audit module is used for material data information audit and compliance document audit. If the material data information audit is passed, the test requirements and compliance document requirements will be issued to the first party. If the compliance document audit is passed, the data will be archived.

[0025] The data analysis module is used to perform statistical analysis on the archived data.

[0026] According to the management system for rail transit vehicle products of an embodiment of the present invention, the basic database module is also used to pre-set a chemical substance library, including the Chinese and English names of the substances, chemical substance registration numbers, European Existing Commercial Chemicals Catalog numbers, physical and chemical properties, and hazard classification information.

[0027] The management system for rail transit vehicle products according to an embodiment of the present invention further includes an environmental protection control module for presetting control planning, implementation plans and implementation details.

[0028] The management system for rail transit vehicle products according to an embodiment of the present invention further includes a material management module for creating new material data and component BOM structure.

[0029] According to the management system for rail transit vehicle products of an embodiment of the present invention, the material data information includes the BOM structure of the components and the material data information of the components at each level, such as the material name, material type, unit weight, and quantity.

[0030] According to the management system for rail transit vehicle products of an embodiment of the present invention, the compliance documents include a letter of commitment, a declaration of conformity, test data and SVHC declaration, a test report, a safety data sheet and a material composition table.

[0031] The embodiment of the present invention also provides a management method for rail transit vehicle products, comprising the following steps:

[0032] Import the BOM structure of rail transit vehicles into the BOM management module and send each component BOM to the corresponding first party;

[0033] The basic database module presets the material categories and their correspondence with the compliance documents. In the regulatory standards management module, the interpreted regulatory standards control requirements are structured and associated with the material categories in the basic database to obtain structured data corresponding to the material control requirements and material categories.

[0034] The first party declares the component material data information through the declaration module and submits it on the system;

[0035] The second party reviews the component material data information submitted by the first party through the review module. If the review is passed, the system will automatically associate the material testing requirements and compliance document requirements by material category and send them to the first party;

[0036] The first party tests the materials according to the testing requirements given by the system, prepares the corresponding information according to the compliance document requirements, and declares the compliance document through the declaration module;

[0037] The second party reviews the compliance documents through the audit module. After passing, the system archives the data of all nodes according to the BOM structure of rail transit vehicle products;

[0038] The data analysis module performs statistical analysis on the archived data.

[0039] According to the management method for rail transit vehicle products of an embodiment of the present invention, the data analysis module performs statistical analysis on the archived data, specifically including calculation of the total amount of SVHC in the product, analysis of the amount of intentionally released substances, and analysis of the amount of hazardous substances.

[0040] According to the management method for rail transit vehicle products of an embodiment of the present invention, the second party reviews the component material data information submitted by the first party through the review module. If the review is passed, the system will automatically associate the material testing requirements and compliance document requirements by material category, and send them to the first party. For complex components, the compliance document requirements will be modified after risk assessment of the materials.

[0041] The management system and method for rail transit vehicle products provided by the embodiment of the present invention, the regulatory standards management module of the system structures the data of applicable regulatory standards, and associates each substance with the material category to be tested according to the control scope of the controlled substances; the basic database module presets the material category and the corresponding compliance document requirements; the supplier declares the component material data information through the declaration module, and after the host factory passes the review, the system can automatically associate the testing requirements and compliance document requirements of each material, and send them to the supplier; for complex components, the host factory can also modify the compliance document requirements for materials with low risk levels during the review to reduce the number of tests. This function solves the problem that suppliers are not clear about the test items and do not know how to execute them, thereby achieving convenient management and efficient and convenient effects.

[0042] The system can compare the test results reported by suppliers with regulatory control requirements and automatically determine whether they are qualified. This overcomes the problem of heavy workload of manual review in existing control methods and the limitation of existing systems that only judge the material composition information, thereby improving review efficiency.

[0043] The system's data analysis module realizes the functions of SVHC calculation, statistics of intentionally released substances and statistics of other hazardous substances, which makes it easier for OEMs to judge whether they are compliant and whether they have obligations such as notification or registration. It solves the problems of low efficiency of manual statistics in existing management and control methods and the lack of such functions in existing systems, thereby achieving convenience, speed and accurate data.

[0044] In addition, the system's environmental management and control module has pre-set management and control planning, implementation plan and implementation details document templates. The template framework is fixed content. The regulatory control requirements obtain the latest system data from the regulatory standards management module. Once the regulatory content is updated, a new management and control document can be generated, which solves the problem of untimely updating of regulatory requirements for implementation details in the existing management and control methods, thereby achieving the effect of improving efficiency and accurate content.

[0045] Suppliers can create new materials and assign material category characteristics through the system's material management module. When building component BOMs, they can reference materials in the material management module for parts of the same material. When filling out compliance documents (such as test data, test reports, safety data sheets, material composition tables), they only need to fill out and refresh once to add data to all parts of the same material. This solves the problem of existing management and control methods that require manual verification and confirmation one by one, thereby achieving a convenient and quick effect.

[0046] The system can archive the compliance documents of each component and material under each assembly according to the BOM structure of rail transit vehicles, and can quickly locate any compliance document of any material, solving the problem of large amount of archived data and difficult to find in the existing management and control methods, thereby achieving a convenient and fast effect.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a management system for rail transit vehicle products, including multiple modules, mainly including a BOM management module, a basic database module, a regulatory standard management module, a declaration module, an audit module and a data analysis module.

[0052] The BOM (Bill of Material) management module is used to import the BOM structure of rail transit vehicles and send the BOM of each component to the corresponding first party (the first party in this embodiment is the supplier).

[0053] The basic database module is used to preset material categories and the correspondence between material categories and compliance documents.

[0054] The regulatory standards management module is used to structure the data of regulatory standards control requirements and obtain structured data corresponding to material control requirements (such as testing or declaration) and material categories.

[0055] The declaration module is used for material data information declaration and compliance document declaration; specifically, material data information includes the BOM structure of the component and material data information of each level of parts, such as material name, material type, unit weight, quantity, etc. Compliance documents include a letter of commitment, a declaration of conformity, test data and SVHC (substances of very high concern) declaration, test report, safety data sheet and material composition table, etc.

[0056] The audit module is used for material data information audit and compliance document audit. If the material data information audit is passed, the test requirements and compliance document requirements will be issued to the first party. If the compliance document audit is passed, the data will be archived.

[0057] The data analysis module is used to perform statistical analysis on the archived data.

[0058] The regulatory standards management module structures the data of applicable regulatory standards, and associates each substance with the material category that should be tested according to the control scope of controlled substances; the basic database module presets the material category and the corresponding compliance document requirements; suppliers declare component material data information through the declaration module, and after the OEM's review and approval, the system can automatically associate the testing requirements and compliance document requirements of each material and send them to the supplier; this function solves the problem that suppliers are unclear about the testing items and do not know how to execute them, thereby achieving convenient management and efficient and convenient results.

[0059] The system can compare the test results reported by suppliers with regulatory control requirements and automatically determine whether they are qualified. This overcomes the problem of heavy workload of manual review in existing control methods and the limitation of existing systems that only judge the material composition information, thereby improving review efficiency.

[0060] The system's data analysis module realizes the functions of SVHC calculation, statistics of intentionally released substances and statistics of other hazardous substances, which makes it easier for OEMs to judge whether they are compliant and whether they have obligations such as notification or registration. It solves the problems of low efficiency of manual statistics in existing management and control methods and the lack of such functions in existing systems, thereby achieving convenience, speed and accurate data.

[0061] According to the management system for rail transit vehicle products of an embodiment of the present invention, the basic database module is also used to pre-set a chemical substance library, including the Chinese and English names of the substances, chemical substance registration numbers, European Existing Commercial Chemicals Catalog numbers, physical and chemical properties, and hazard classification information.

[0062] The management system for rail transit vehicle products according to an embodiment of the present invention also includes an environmental protection control module for presetting control planning, implementation plans and implementation details. The environmental protection control module pre-sets the control planning, implementation plan and implementation details file templates, and the template framework is fixed content. The regulatory control requirements obtain the latest data of the system from the regulatory standards management module. Once the regulatory content is updated, a new control document can be generated, which solves the problem of untimely updates of regulatory requirements for implementation details in the existing control method, thereby achieving the effect of improving efficiency and accurate content.

[0063] The management system for rail transit vehicle products according to an embodiment of the present invention also includes a material management module for creating new material data and component BOM structure. Suppliers can create material data, including material name, material category, and application scenario, etc., wherein the material category obtains data from the basic database module and can be selected. The materials created by this module are mainly used for reference when declaring component material data information. Suppliers can create component BOM structure for reference when declaring component material data information.

[0064] Suppliers can create new materials and assign material category characteristics through the system's material management module. When building component BOMs, they can reference materials in the material management module for parts of the same material. When filling out compliance documents (such as test data, test reports, safety data sheets, material composition tables), they only need to fill out and refresh once to add data to all parts of the same material. This solves the problem of existing management and control methods that require manual verification and confirmation one by one, thereby achieving a convenient and quick effect.

[0065] The system can archive the compliance documents of each component and material under each assembly according to the BOM structure of rail transit vehicles, and can quickly locate any compliance document of any material, solving the problem of large amount of archived data and difficult to find in the existing management and control methods, thereby achieving a convenient and fast effect.

[0066] The embodiment of the present invention also provides a management method for rail transit vehicle products, comprising the following steps:

[0067] Import the BOM structure of rail transit vehicles into the BOM management module, and send each component BOM to the corresponding first party (supplier);

[0068] The basic database module presets the material categories and their correspondence with the compliance documents. In the regulatory standards management module, the interpreted regulatory standards control requirements are structured and associated with the material categories in the basic database to obtain structured data corresponding to the material control requirements and material categories.

[0069] The first party declares the component material data information through the declaration module, that is, the component is further divided into parts made of uniform materials according to the component BOM structure, and the material data information of each part (including material name, material category, unit weight, quantity, etc.) is filled in and submitted on the system;

[0070] The second party (OEM) reviews the component material data information submitted by the first party through the review module. If the review is passed, the system will automatically associate the material testing requirements and compliance document requirements by material category and send them to the first party;

[0071] The first party tests the materials according to the testing requirements given by the system, and prepares the corresponding information according to the compliance document requirements, such as a letter of commitment, a declaration of conformity (regulatory compliance, intentional release of substances, etc.), test data and SVHC declaration, test report, safety data sheet or material composition table, etc., and declares the compliance documents through the declaration module;

[0072] The second party reviews the compliance documents through the audit module. After passing, the system archives the data of all nodes according to the BOM structure of rail transit vehicle products;

[0073] The data analysis module performs statistical analysis on the archived data, including calculation of the total amount of SVHC in the product, analysis of the amount of intentionally released substances, and analysis of the amount of other hazardous substances.

[0074] The management method of this embodiment realizes real-time monitoring of product green compliance, identification of risks and regulatory obligations, and improves work efficiency through process management of environmental protection control planning, formulation of implementation plans, declaration and review of material information and environmental protection data, and data analysis. The regulatory standards management module structures the data of applicable regulatory standards, and associates each substance with the material category to be tested according to the control scope of controlled substances; the basic database module presets the material category and the corresponding compliance document requirements; suppliers declare component material data information through the declaration module, and after the OEM's review is passed, the system can automatically associate the testing requirements and compliance document requirements of each material and send them to the supplier; this function solves the problem that suppliers are not clear about the test items and do not know how to execute them, thereby achieving convenient management and efficient and convenient results.

[0075] According to the management method for rail transit vehicle products of the embodiment of the present invention, the second party reviews the component material data information submitted by the first party through the review module. If the review is passed, the system will automatically associate the material testing requirements and compliance document requirements by material category, and send it to the first party. For complex components, the material risk assessment is performed on the material and the compliance document requirements are modified. For complex components, the OEM can also modify the compliance document requirements for materials with low risk levels during the review to reduce the number of tests.

[0076] According to the control scope of controlled substances in regulatory standards, controlled substances are associated with material categories; the material data information of components reported by suppliers also includes material categories, so standardized testing requirements can be provided to suppliers.

[0077] The basic database has preset compliance document requirements corresponding to different material categories. Suppliers can automatically associate these requirements when filling in material data information, and can also modify them based on the risk level of the material.

[0078] Suppliers can create new materials and assign material category characteristics through the system's material management module. When building component BOMs, they can reference the same material for parts of the same material. When filling out compliance documents (such as test data, test reports, safety data sheets, and material composition tables), they only need to fill out the documents once and then refresh to add data to all parts of the same material.

[0079] The system's data analysis module can perform statistical analysis on the aggregated data, including calculation of the total amount of SVHC in the product, analysis of the amount of intentionally released substances, and analysis of the amount of other hazardous substances, to help OEMs identify the legal obligations they should fulfill.

[0080] The environmental protection control module of the system has preset control planning, implementation plan and implementation details document templates. The template framework is fixed content. The regulatory control requires obtaining the latest system data from the regulatory standards management module. Once the regulations are updated, a new document can be quickly generated.

[0081] The system can archive the compliance documents of each component and material under each assembly according to the BOM structure of rail transit vehicles, and can quickly locate any compliance document of any material.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
