Description

Technical Field

[0001] The present invention belongs to the technical field of data processing, and in particular relates to a sulfur hexafluoride full life cycle management and control platform based on Internet of Things technology. Background Art

[0002] Sulfur hexafluoride is one of the six major greenhouse gases, with a greenhouse effect 23,900 times that of carbon dioxide, making it the gas with the strongest greenhouse effect known in the world. However, due to its good insulation and arc extinguishing properties, it has become an important working fluid for the safe and stable operation of power systems, 80% of which comes from the power industry. In addition, there are a large number of gas-using equipment, a scattered layout, and many entities involved, which makes the gas control process complicated and difficult. The following problems exist in the control process:

[0003] (1) There are many participants, information collection is difficult, and there is a lack of consensus: The entire sulfur hexafluoride industry involves multiple departments, and different departments are responsible for different business functions, such as: the department responsible for the detection of sulfur hexafluoride core indicators, the department responsible for the recovery and treatment of sulfur hexafluoride and the maintenance of recovery equipment, the department responsible for the recovery, treatment and maintenance of in-service equipment, etc., and these participants will generate their own data. How to collect the data generated by these participants into the application platform and reach consensus and mutual trust among them has always been a pain point and difficulty in industry management and control;

[0004] (2) There are many data silos and the process is not easy to connect: There are data silos between equipment use and gas consumption, production plans and actual work. The sulfur hexafluoride circulation data cannot be shared, the disclosure of emission reduction data information is not transparent enough, and the data information governance capacity is insufficient. The emission reduction data are independent of each other, making it difficult to effectively monitor, check and verify the sulfur hexafluoride circulation data;

[0005] (3) The data chain is long and reliable traceability is difficult: Sulfur hexafluoride emission reduction covers the entire chain of daily equipment leakage, gas recovery, gas purification and recycling. The information on gas flow, recovery and recycling process, as well as the information on normal equipment leakage and gas replenishment process cannot be reliably traced, resulting in shortcomings in data supervision.

[0006] Therefore, how to use Internet thinking, integrate management methods and technical means, and reduce sulfur hexafluoride gas emissions is a technical problem that urgently needs to be solved in the power industry's sulfur hexafluoride control. Summary of the invention

[0007] The present invention aims to address the technical problems existing in the background technology and provide a sulfur hexafluoride full life cycle management and control platform based on the Internet of Things technology to standardize the process data chain process of each business link in the full life cycle of sulfur hexafluoride, so as to achieve multi-subject joint promotion of sulfur hexafluoride emission reduction results, reduce greenhouse gas emissions, and form a replicable and popularizable full-process experience of sulfur hexafluoride recycling and reuse, thereby improving the efficiency and benefits of sulfur hexafluoride emission reduction.

[0067] Compared with the prior art, the beneficial effects of the present invention are:

[0068] (1) The present invention relies on the Internet of Things technology and utilizes the characteristics of blockchain such as decentralization, data immutability, and full traceability, which meets the technical difficulties in sulfur hexafluoride emission reduction and builds a coordinated emission reduction linkage mechanism for the upstream and downstream sulfur hexafluoride industry chain. Through service incentives such as supplier services, regulatory data query and traceability, centralized gas control, and emission reduction benefit sharing, a consensus on coordinated emission reduction is reached among multiple subjects such as verification agencies, equipment suppliers, and gas users, and a sulfur hexafluoride emission reduction control ecosystem is jointly created. The specific links and processes of sulfur hexafluoride production, circulation, and consumption are combined into a chain data structure in chronological order, and encryption technology is used to ensure that it cannot be tampered with or forged, forming a sulfur hexafluoride emission data evidence chain, which significantly improves the efficiency and benefits of sulfur hexafluoride emission reduction and achieves a win-win situation for all parties. At the same time, it encourages multiple subjects to voluntarily fulfill their sulfur hexafluoride emission reduction responsibilities, and plays a leading role in promoting social greenhouse gas emission reduction.

[0069] (2) The improved sulfur hexafluoride full life cycle management and control platform based on the Internet of Things technology of the present invention can develop an identity authentication module to distinguish the permissions of different subjects for the production, circulation, use, recycling and reuse of sulfur hexafluoride in terms of data chain, so as to achieve the safe isolation of business domain data; in terms of application services, it provides personalized services for the subjects participating in emission reduction from the perspective of multiple subjects, such as: providing services such as total sulfur hexafluoride control, emission reduction benefit analysis, multi-dimensional data traceability, supplier management, gas distribution statistics, and plan management in actual production within the company's business scope from the perspective of the power grid; and performing statistical analysis of regulatory data and one-click generation of verification reports from the perspective of supervision, which promotes the improvement of sulfur hexafluoride emission reduction efficiency and benefits, and makes the use and operation safer, more efficient and convenient;

[0070] (3) The data layer of the present invention performs adaptation and normalization processing on heterogeneous data when modeling the underlying data. In the data processing process, a multi-layer architecture is established to collect, clean, normalize the domain and store the data itself. Each layer of the architecture is implemented using the adapter mode, ensuring the adaptability of the management and control platform to complex business affairs.

[0071] (4) The data layer of the present invention can automatically generate smart contracts, establish data chain smart contracts for different business processes for the production, circulation, use, recycling and reuse of sulfur hexafluoride, and classify sulfur hexafluoride business data into three categories according to the degree of confidentiality, and standardize the chain conditions for information on sulfur hexafluoride business data of different confidentiality levels. When the data chain smart contract is triggered, the relevant sulfur hexafluoride business data will be chained according to the content specified in the contract, so that the data information of each link of sulfur hexafluoride production, circulation, consumption, etc. forms an unalterable data blockchain in a preset order, thereby ensuring the integrity, security and transparency of the data; in this way, all relevant parties can obtain sulfur hexafluoride business data in real time and accurately, improve management efficiency, reduce human errors, and effectively prevent data tampering and information leakage, so as to achieve refined management of the entire life cycle of sulfur hexafluoride;

[0072] (5) The data layer of the present invention adopts the LRU-K algorithm to classify the stored data into three categories: hot data, cold data and reserve data. By identifying frequently accessed data as hot data and storing it in the cache first, marking infrequently accessed data as cold data and storing it on a slower storage medium, and marking data that may be accessed as reserve data, the data storage management is optimized and the data access speed is significantly improved, thereby effectively improving the response speed and overall performance of the system.

[0073] (6) The present invention also proposes business process data storage based on distributed accounting technology, and differentiates the business flow data of the circulation, use, recovery and recycling of sulfur hexafluoride, analyzes three types of data: static data (data on tools, equipment, etc.), dynamic data (flow data) and business data (plan information data), and uploads the various business data of sulfur hexafluoride to the chain in accordance with the provisions of distributed accounting technology, so that the business data information of each link of sulfur hexafluoride production-circulation-consumption forms an unalterable data block in a preset order, thereby ensuring the integrity, security and transparency of the data; this method can not only prevent data tampering and loss, but also realize real-time sharing and traceability of data in each link, improve management efficiency, reduce operating costs, and ensure the efficiency and reliability of sulfur hexafluoride life cycle management.

[0082] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0083] Combination Figure 1 As shown, an embodiment of the present invention provides a sulfur hexafluoride full life cycle management and control platform based on Internet of Things technology, including an infrastructure layer, a data layer, a business support layer, a business layer and a display layer. The following is a detailed introduction to each layer structure.

[0084] A. Infrastructure layer

[0085] The infrastructure layer is based on the blockchain foundation of "one master, two sides and multiple slaves", and the power grid sulfur hexafluoride emission reduction management and control platform is deployed on the blockchain slave chain, and a sulfur hexafluoride business system is generated based on the existing blockchain slave chain.

[0086] Among them, "one master, two sides and multiple slaves" refers to the existing blockchain, including one main chain, two side chains and N business slave chains (also known as blockchain slave chains). The side chains include transaction side chains and data side chains.

[0087] Main chain: used to provide company-level blockchain service interfaces to the outside world, provide trusted evidence storage services, provide some public services and contract interactions for transaction side chains and data side chains, and realize electronic bill sharing, security and multi-subject collaboration;

[0088] Transaction sidechain: used to provide support for power grid transaction business, including distributed power transaction business support, energy finance business support and multilateral transaction matching business support. It can realize transaction information traceability and process management, improve transaction transparency and process controllability;

[0089] Data sidechain: used to provide data services, including data security, data value-added and data sharing services, provide commercial value-added services for energy big data analysis, conduct unified data management, and solve data trust sharing and privacy protection;

[0090] Business slave chain: Provide cross-chain deployment services. Each provincial company will interact and expand information with the main and side chains to achieve horizontal and vertical information interaction.

[0091] B. Data Layer

[0092] The data layer is the core of the power grid sulfur hexafluoride emission reduction management and control platform. The data layer preprocesses and models the business data of sulfur hexafluoride, and generates corresponding smart contracts for the sulfur hexafluoride business process data on the chain based on the abstracted multi-category data models.

[0093] When modeling data, it is necessary to adapt and normalize heterogeneous data. The specific process is as follows:

[0094] Whether it is the storage data generated by the project itself or the regulatory data obtained from the underlying chain (such as node information, user information, block information, transaction information, etc.), it will involve the processing of a large amount of heterogeneous data. The characteristics of this type of heterogeneous data are as follows:

[0095] (1) Different data formats;

[0096] (2) The data transmission method is different from the Unicom interface;

[0097] (3) There are differences in data types and representation methods;

[0098] (4) The meaning of data varies in different contexts.

[0099] The above characteristics of heterogeneous data increase the difficulty of underlying data modeling, and heterogeneous data need to be adapted and normalized. During the data processing process, a multi-layer architecture needs to be established to collect, clean, normalize the domain, and store the data in a hierarchical manner. Each layer of the architecture is implemented using the adapter model to ensure the adaptability of the project to complex business transactions.

[0100] The adapter pattern can be used as both a class structure pattern and an object structure pattern. In the adapter pattern, the problem of interface incompatibility can be solved by optimizing the adapter.

[0101] The implementation of the adapter pattern mainly includes:

[0102] Target (target abstract class): The target abstract class defines the interface required by the user. It can be an abstract class or interface, or a concrete class.

[0103] Adapter (Adapter class): The adapter can call another interface as a converter to adapt the Adaptee (adapter class, which is the component that needs to be accessed and adapted) and the Target. The adapter class is the core of the adapter pattern. In the object adapter, it connects the two by inheriting the Target and associating an Adaptee object.

[0104] When combined with business, all business triggering, business data on-chain storage, and traceability operations need to be implemented through smart contracts. The project implementation process is cumbersome and complicated, and the efficiency of contract implementation needs to be improved. Therefore, Figure 2 As shown, the data layer of the embodiment of the present invention has the function of automatically generating smart contracts, and the efficiency of smart contracts is significantly improved by quickly generating smart contracts.

[0105] like Figure 2 As shown, the method for automatically generating a smart contract specifically includes:

[0106] First, analyze different businesses, define them independently according to the operation status of business codes, and form corresponding structured business modeling data. Business modeling data supports PDM, json and xml formats. At the same time, logically summarize the smart contracts corresponding to different businesses to form business templates. Business templates support C / C++ templates, JAVA templates, G language templates, HTML language templates and python templates.

[0107] Then, the business modeling data, business template and configuration information of the configuration file are read through the automatic generation tool (i.e., the automatic generation code module), and the corresponding business template data is established;

[0108] Finally, the business modeling data is parsed and the corresponding smart contract file is automatically generated according to the business template.

[0109] The data layer adopts the above-mentioned method of automatically generating smart contract files, and establishes data chain smart contracts for different business processes for the production, circulation, use, recovery and recycling of sulfur hexafluoride, and divides the sulfur hexafluoride business data into three categories according to the degree of confidentiality, as shown in Table 1 below. At the same time, the chain conditions for sulfur hexafluoride business data information of different confidentiality levels are standardized. When the data chain smart contract is triggered, the relevant sulfur hexafluoride business data will be chained according to the content specified in the contract, so that the business data information of each link of sulfur hexafluoride production-circulation-consumption, etc., forms an unalterable data blockchain in a preset order.

[0110] Table 1 Three types of data chain planning

[0111]

[0112] At the same time, the data layer uses the LRU-K algorithm to distinguish the stored data, specifically dividing the stored data into three categories: hot data, cold data and reserve data, where:

[0113] Hot data: As the first-level cache data, the management and control platform designs storage redundancy according to business requirements and stores it according to its own organizational data structure. Users have the fastest access speed to hot data.

[0114] Prepared data: can be redundantly placed in a side-mounted relational database as secondary cache data, thereby ensuring superior access speed. Users can access prepared data relatively quickly.

[0115] Cold data: No cache processing is performed. In each level of cache, data will change as access changes, and this change decision also needs to be guided by localized business domain knowledge to optimize the access speed to the service.

[0116] In addition, the data layer also includes business process data storage based on distributed accounting technology, and its storage method specifically includes:

[0117] In view of the differentiation of business flow data in the circulation, use, recovery, processing and recycling of sulfur hexafluoride, three types of data are analyzed, namely static data (data on tools, equipment, etc.), dynamic data (flow data) and business data (plan information data). The business data of sulfur hexafluoride are uploaded to the chain in accordance with the provisions of distributed accounting technology, so that the business data information of each link of sulfur hexafluoride production, circulation and consumption forms an unalterable data block in a preset order.

[0118] According to the differentiation of sulfur hexafluoride business flow data, the storage structure of business process data storage based on distributed accounting technology specifically includes:

[0119] Sulfur hexafluoride static storage distributed accounting module, specifically including: storage of charging power equipment data, verification equipment data, static file data, operator information data, recycling and recharging device data, purification data, weighing equipment data, and pressure vessel data;

[0120] Sulfur hexafluoride dynamic storage distributed accounting module, including: storage of data on gas storage, outbound storage, refilling, recycling, purification and quality inspection;

[0121] The distributed accounting module for sulfur hexafluoride business data specifically includes: equipment maintenance plan, equipment decommissioning and recycling plan, new equipment gas filling plan, gas-filled power equipment emergency repair events, and gas-filled power equipment gas replenishment events and other plan information data storage.

[0122] like Figure 3 The data architecture diagram of the data layer is shown. According to the data flow direction, the data architecture of the data layer includes: business scenario layer, business flow and data storage, and data display layer.

[0123] Among them, all data trigger points are triggered by the business scenario layer. The business scenarios that can trigger data flow in the system include: equipment maintenance, equipment decommissioning, equipment purchase, emergency repair and gas purchase, etc. These business scenarios can trigger one or more links in the business flow. In these links, the data that needs to be stored on the chain in each link is stored on the stack from the chain through the data entry App. In these processes, some file information also needs to be stored, such as: photo evidence image information, test report information, and invoice and other file information in the business flow link. These file information cannot be directly stored on the chain. First, these file information is stored in the object storage system of the intranet, and then the storage path of the file information and the authentication hash value (file authentication information) are stored as data that needs to be stored on the chain on the stack from the chain. The upper layer is the data display layer, which performs multi-dimensional retrieval and analysis of the data on the chain to meet the needs of external data display.

[0124] Correspondingly, the data flow of the data layer specifically includes the following four links:

[0125] First, in the Internet area, operators trigger business scenario layers (such as equipment maintenance, equipment retirement, equipment purchase, emergency repair, and gas purchase) through data entry apps. Operators will also enter some data according to the current operation situation at this stage.

[0126] Second, after the event is triggered, the data will reach the six circulation links in the business flow, including gas recovery link, gas storage link, gas purification link, gas storage link, gas refill link, and gas detection link. Taking the gas recovery link as an example, in the gas recovery link, the gas recovery equipment information, the recovery device information used, the weight of the recovered gas, the recovery rate information, and the pressure vessels into which the recovered gas is filled are stored on the chain;

[0127] Third, the data stored on the chain during the business flow will be stored in the stack in the data storage chain to complete the data storage;

[0128] Fourth, the data display layer displays data to the outside world.

[0129] The first link mentioned above is completed in the Internet environment, and the second, third and fourth links are completed in the extranet environment of the Internet region. It should be noted that in the second link, there is also a part of the data as file information, such as the picture information taken as evidence in the process of gas recovery, which is to be saved in the object storage device of the intranet. The flow of this part of the file information is: first store the file information in the information management area of ​​the intranet, and then store the storage path of the file information and the authentication hash value on the data chain. The Internet region here refers to: an area divided by the company's internal network, in which external resources can be accessed, but external access to internal data is restricted.

[0130] C.Business support layer

[0131] The business support layer is mainly to meet the subsequent business functions and business service expansion needs, provide a unified processing interface to the upper business layer, and make the upper business differences transparent so that the upper business can better meet the smooth expansion of the business;

[0132] The business support layer is the link between the underlying data chain and the upper-layer application. The business support layer can provide a unified data processing interface to the business layer through service middleware or calling a third-party platform. At the same time, it also shields the differences between different metadata to the outside, making the upper-layer business call simpler and more unified.

[0133] like Figure 4 As shown, taking the maintenance plan business as an example, the business processing methods for various municipal companies, processing centers, and third-party gas recovery companies may be different, and the generated data structures may also be different.
