Description

Technical Field

[0001] This invention belongs to the field of oil pipeline management technology, specifically relating to a high-pressure pipeline valve information management system and method based on dual-path extended blockchain. Background Technology

[0002] Drilling and downhole operations are crucial components of oil and gas exploration and development. With the increasing enthusiasm for unconventional oil and gas resource exploration and development in my country, fracturing operations are also becoming more frequent at oil and gas development sites. Drilling, downhole operations, and fracturing operations require the establishment of high-pressure manifold processes. These high-pressure manifolds involve a wealth of information regarding the use of pipes and valves. Under the traditional management model of operating companies, a large amount of data related to the use of these pipes and valves requires manual statistics and management. Once pipes and valves are released from the warehouse and arrive at the construction site, it is difficult for staff to accurately and in real-time track their usage. Furthermore, it is impossible to effectively allocate resources based on the usage of these pipes and valves. This results in issues such as pipes and valves remaining unused for extended periods after being released from the warehouse, untimely maintenance, unclear disposal dates, and difficulty in tracing lost pipes and valves, leading to low management efficiency. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, namely the large amount of manual statistics required for pipe and valve components and the inability to obtain their usage status in real time, this invention provides a high-pressure pipe and valve component information management system and method based on a dual-path extended blockchain.

[0004] The first aspect of this invention discloses a high-pressure pipe valve information management system based on a dual-path extended blockchain. The system includes a data acquisition module, a blockchain information intelligent extension mechanism module, a pipe valve full life cycle information management module, and a pipe valve life early warning module. The blockchain information intelligent extension mechanism module is signal-connected to the data acquisition module; the pipe valve full life cycle information management module is signal-connected to the blockchain information intelligent extension mechanism module; and the pipe valve life early warning module is signal-connected to the pipe valve full life cycle information management module.

[0005] The data acquisition module is configured to collect on-site usage data of pipe valves and transmit the data to the blockchain information intelligent expansion mechanism module for storage in the blockchain network node.

[0006] The blockchain information intelligent expansion mechanism module is configured to expand, reach consensus, or track blockchain information.

[0007] The valve and pipe fitting lifecycle information management module is configured to access the valve and pipe fitting usage information in the blockchain and classify, statistically analyze, and display the information on a webpage to provide valve and pipe fitting information management.

[0008] The valve life warning module is configured to be integrated into the valve life information management module to obtain abnormal usage status of valves in real time and generate warning information.

[0009] In some preferred embodiments, the data acquisition module is a blockchain-based RFID data network system, with RFID tags installed on the pipes and valves, and each RFID tag's electronic ID corresponding one-to-one with the device number of each pipe and valve.

[0010] In some preferred embodiments, the data acquisition module further includes a handheld scanning device, which is used to identify RFID tags and perform batch operations on RFID tags to complete the input, editing or viewing of information on the same type of pipe and valve fittings.

[0011] The handheld scanning device may be one or more, and each handheld scanning device corresponds to a network node.

[0012] In some preferred embodiments, the data acquisition module collects pipe and valve usage data including wall thickness, liquid flow rate, sand flow rate, and construction pressure.

[0013] In some preferred embodiments, the blockchain information intelligent expansion mechanism module includes a blockchain information expansion module and a blockchain network node status control module.

[0014] The blockchain information expansion module includes a first expansion module and a second expansion module. The first expansion module is configured to add corresponding network nodes based on the increase in the number of handheld scanning devices, forming a main path for blockchain information expansion. The second expansion module is configured to increase the amount of data on a single network node based on the increase in the number of scans by the handheld scanning device, forming a secondary path for blockchain information expansion.

[0015] The blockchain network node state control module includes an active mechanism module and a silent mechanism module. The active mechanism module is configured for interconnection between pairs of nodes, consensus verification, and data noise removal. The active node data information in the active mechanism module can be actively accessed by the valve and pipe fitting lifecycle information management module, and access information arranged in chronological order is automatically generated after its active access. The silent mechanism module is configured for node isolation.

[0016] In some preferred embodiments, the consensus mechanism used by the first extension module and the second extension module is different.

[0017] The blockchain information intelligent expansion mechanism module also includes a traceability module, which is embedded in the blockchain settings. Based on the problem data in the valve and pipe fitting full life cycle information management module, the traceability module automatically tracks the physical address of the handheld scanning device and obtains the network node information corresponding to the problem data.

[0018] In some preferred embodiments, the pipe and valve full life cycle information management module includes an information input module, an information statistics and query module, and a system setting module; the information input module is configured to process information on pipe and valve entry and exit, manually input RFID tags, and modify and edit pipe and valve information.

[0019] The information statistics and query module includes a basic information query module, a map area statistics module, a life cycle statistics module, and an inventory information query module to meet users' query needs for pipe and valve information.

[0020] The system settings module is configured to include user login, unit information management, user information management, permission management, and log management.

[0021] In some preferred embodiments, the system further includes a data retrieval module to embed the valve life warning module into the valve life information management module.

[0022] In some preferred embodiments, the ratio of the used time of the pipe valve to the preset used time is δ. When δ ≥ 95%, the pipe valve life warning module issues an alarm signal, and the corresponding pipe valve is immediately stopped from use.

[0023] When 80% ≤ δ < 95%, the pipe and valve life warning module will classify the corresponding pipe and valve into the maintenance module.

[0024] The second aspect of the present invention discloses a high-pressure pipe valve information management method based on a dual-path extended blockchain. The method is based on the high-pressure pipe valve information management system based on a dual-path extended blockchain as described above, and includes the following steps: Step S100, the data acquisition module collects the on-site usage data information of the pipe valve and transmits the data information to the blockchain information intelligent extension mechanism module for storage in the blockchain network node.

[0025] When an electronic tag is damaged, a new electronic tag is bound to the system according to the device number, and the original device usage information is saved. The RFID tag is identified by a handheld scanning device to enter, edit and view the usage information of pipe valves.

[0026] In step S200, the blockchain information intelligent expansion mechanism module stores the RFID data information identified by the handheld scanning device to the corresponding blockchain network node for distributed storage of valve usage data. Among them, the network nodes for generating valve data in the same project department and different work teams are the same block, and the valve data storage format between different project departments is consistent, thus forming a blockchain.

[0027] In step S300, the physical address of the handheld scanning device is automatically tracked through the traceability module embedded in the blockchain, based on the problem data in the valve and pipe fitting lifecycle information management module, and the network node information corresponding to the problem data is obtained.

[0028] In step S400, the pipe and valve life warning module is embedded into the pipe and valve full life cycle information management module through the data call program module. For pipe and valve components that meet the alarm conditions, alarm information is generated in real time and can be displayed in the form of a floating window. Users can click on the floating window to view the detailed information of the alarmed pipe and valve components.

[0029] The beneficial effects of this invention are as follows:

[0030] 1) The present invention discloses a high-pressure pipe valve information management system and method based on dual-path extended blockchain. It uses a hierarchical, multi-level, and multi-means security control mechanism for data management and transmission. It uses the device number and device key built into the system for verification to ensure secure system login. It adopts multiple data serialization methods to support encrypted data transmission, enabling the Internet of Things management system to resist data attacks, prevent unauthorized access, and ensure data security.

[0031] 2) In this invention, RFID tags are installed on pipe valves to generate digital identity IDs. On-site handheld scanning devices identify RFID tags, and pipe valve usage data can be recorded and written to the blockchain, realizing distributed storage of pipe valve usage data. A consensus mechanism is used to achieve interconnection of node data. At the same time, node "active" / "silent" settings are adopted to prevent the information system from accessing the data of attacked nodes, ensuring stable information data transmission and smooth operation of the information management system.

[0032] 2) The blockchain information intelligent expansion mechanism developed in this invention adopts a dual-path, dual-mechanism blockchain information expansion and consensus mechanism, which ensures the reliability and security of the information management system accessing the data.

[0033] 3) Based on field and indoor experimental data, this invention constructs a pipe and valve life early warning model, considers the environmental conditions of pipe and valve use, calculates the life loss rate of pipe and valve, and uses a floating window message alarm in the information management system for pipe and valve with a life loss rate of more than 90% to remind users to replace the alarmed pipe and valve in time to ensure the safety of pipe and valve use in the field.

[0034] 4) The solution disclosed in this invention, based on RFID tag-based Internet of Things (IoT) technology, provides an effective way to efficiently and rationally allocate and use pipe fittings. This technology associates physical tools with RFID tags, uses scanning equipment to record and transmit the information of the physical tools corresponding to the RFID tags to the Internet, forming a network connecting people and things, and things with each other, without time or geographical limitations. On the IoT, staff can check the usage information of pipe fittings in real time and manage them centrally, improving management efficiency. However, the centralized storage of pipe fitting data information based on RFID tags in IoT technology poses a risk of low data anti-counterfeiting and security. Blockchain, using cryptographic data encryption, multi-node distributed storage, smart contracts, and consensus mechanisms, links blocks together to achieve point-to-point data transmission and a decentralized database system, which can effectively perform data anti-counterfeiting traceability and security management.

[0035] 5) The high-pressure pipe valve information management system and method disclosed in this invention, based on dual-path extended blockchain, addresses the challenges of oilfield enterprises accelerating their informatization efforts and the need for network data security control. It constructs a multi-node distributed storage pipe valve Internet of Things management system, which has a wide range of applications in oil and gas exploration and development construction sites, greatly improving the intelligent management efficiency of on-site pipe valve usage and the effective allocation of on-site resources.

[0042] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0043] The first aspect of this invention discloses a high-pressure pipe and valve information management system based on a dual-path extended blockchain, comprising a data acquisition module, a blockchain information intelligent extension mechanism module, a pipe and valve full life cycle information management module, and a pipe and valve life early warning module. The blockchain information intelligent extension mechanism module is signal-connected to the data acquisition module; the pipe and valve full life cycle information management module is signal-connected to the blockchain information intelligent extension mechanism module; and the pipe and valve life early warning module is signal-connected to the pipe and valve full life cycle information management module. The data acquisition module is configured to collect on-site usage data of pipe and valve components and transmit this data to the blockchain information intelligent extension mechanism module for storage in the blockchain network node; the blockchain information intelligent extension mechanism module is configured to extend, reach consensus on, or track blockchain information; the pipe and valve full life cycle information management module is configured to access the usage information of pipe and valve components in the blockchain and classify, statistically analyze, and display the information on a webpage to provide pipe and valve component information management; the pipe and valve life early warning module is configured to be integrated into the pipe and valve full life cycle information management module, to obtain abnormal usage status of pipe and valve components in real time and generate early warning information.

[0044] This invention establishes a full lifecycle information management module for pipe and valve components based on a "blockchain + IoT + big data" construction model. It aims to improve the management efficiency of pipe and valve components for operating companies. By developing a blockchain program, it achieves distributed storage of RFID tag data identified by handheld devices, ensuring that valid field data is not maliciously attacked or tampered with, and guaranteeing secure data transmission and use. By constructing a pipe and valve component IoT platform system, it transmits the usage information of pipe and valve components to a network platform for management, facilitating real-time access by staff from various departments to the technical data and historical usage of downhole equipment, thereby improving the operating company's management efficiency. By analyzing the pipe and valve component usage data system, it predicts the lifespan of field pipe and valve components, enabling timely issuance of early warning commands for maintenance and replacement, ensuring the safe use of pipe and valve components in the field.

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0046] See attached document Figure 1 To be continued Figure 5The first aspect of the present invention provides a high-pressure pipe valve information management system based on a dual-path extended blockchain. The system includes a data acquisition module, a blockchain information intelligent extension mechanism module, a pipe valve full life cycle information management module, and a pipe valve life early warning module. The blockchain information intelligent extension mechanism module is signal-connected to the data acquisition module; the pipe valve full life cycle information management module is signal-connected to the blockchain information intelligent extension mechanism module; and the pipe valve life early warning module is signal-connected to the pipe valve full life cycle information management module.

[0047] The data acquisition module is configured to collect on-site usage data of pipe valves and transmit this data to the blockchain information intelligent expansion mechanism module for storage in the blockchain network node. Further, the data acquisition module is a blockchain-based RFID data network system. RFID tags are installed on the pipe valves in the field, and each RFID tag's electronic ID corresponds one-to-one with the device number of each pipe valve. In this invention, the RFID tag is bound to the pipe valve, serving as a unique electronic identification for the device. The RFID tag can be fixed using a strapping method, which is convenient and securely fixed.

[0048] Further, refer to the appendix Figure 2 The system demonstrates the IoT management method and implementation process for the entire lifecycle of pipe and valve components, including a two-tier architecture of pipe and valve component information collection and distributed storage, and early warning management for the entire lifecycle of pipe and valve components. The information management system actively accesses and parses data from active blockchain nodes to achieve secure and efficient transmission of RFID data identified by handheld devices.

[0049] The data acquisition module also includes a handheld scanning device, which is used to identify RFID tags and perform batch operations on RFID tags to complete the input, editing or viewing of information on the same type of pipe and valve components. That is, when an electronic tag is damaged, a new electronic tag can be bound to the system according to the device number, and the original device usage information can be saved. The handheld scanning device can input, edit and view the usage information of pipe and valve components by identifying RFID tags.

[0050] There are one or more handheld scanning devices, and each handheld scanning device corresponds to a network node to realize distributed storage of pipe and valve usage data.

[0051] Preferably, a handheld scanning device is used to identify RFID tags. The handheld scanning device can perform batch operations on RFID tags and can process information of the same type of pipe valves in batches. At the same time, the handheld scanning device has the functions of verification code login, automatic location statistics and breakpoint resume function to ensure data security and efficient transmission.

[0052] The data acquisition module collects pipe and valve usage data including wall thickness, liquid flow rate, sand flow rate, and construction pressure. The network nodes generated by the pipe and valve data of different work teams in the same project department are the same block. The data storage format of pipe and valve data between different project departments is consistent, forming a blockchain. The blockchain used in this invention uses a hash algorithm to ensure data transmission security.

[0053] The blockchain information intelligent expansion mechanism module is configured to expand, reach consensus, or track blockchain information.

[0054] Further refer to the appendix Figure 3 It demonstrates two paths, two consensus mechanisms, and the blockchain extension workflow in the blockchain information intelligent extension mechanism module.

[0055] The blockchain information intelligent expansion mechanism module includes a blockchain information expansion module and a blockchain network node status control module. The blockchain information expansion module includes a first expansion module and a second expansion module. The first expansion module is configured to add corresponding network nodes based on the increase in the number of handheld scanning devices, forming the main path for blockchain information expansion. The second expansion module is configured to increase the amount of data on a single network node based on the increase in the number of scans by the handheld scanning devices, forming a secondary path for blockchain information expansion.

[0056] Furthermore, in this invention, there are two paths for expanding blockchain information. The first expansion module and the second expansion module use different consensus mechanisms. The first expansion module uses an account importance algorithm to assign weights to the various functions of the new account and calculate the account importance. If the importance exceeds a set threshold, the main blockchain path expansion is completed, ensuring the integrity of the new account's functions. The second expansion module uses a data relevance algorithm to calculate the relevance of the new data. If the relevance threshold requirement is met, the node data update is completed, and the secondary blockchain path expansion is completed, ensuring the relevance between the new data and the existing data.

[0057] The blockchain network node state control module includes an active mechanism module and a silent mechanism module. Specifically, the active mechanism module sets the network node to "active", and the silent mechanism module sets the network node to "silent", which are the two states of the blockchain network node.

[0058] The active mechanism module is configured to enable interconnection between nodes (i.e., data interconnection between nodes), consensus verification, and noise removal. The active node data information in the active mechanism module can be actively accessed by the valve and pipe fitting lifecycle information management module. After the active access, access information is automatically generated in chronological order. The data of the generated information record cannot be changed after the network node data is updated, preventing malicious data tampering, ensuring data transmission security, and facilitating accurate problem tracing.

[0059] The silent mechanism module is configured to isolate nodes, meaning that node data information is isolated and cannot be verified or accessed by the valve lifecycle information management module. Only after being set to "active" on the handheld scanning device and reaching consensus with other "active" node data can the valve lifecycle information management module actively access it.

[0060] Specifically, the blockchain information expansion process is as follows: the handheld scanning device identifies RFID data information and writes it into the blockchain through two paths, primary and secondary. Information is added to the blockchain network node (secondary path) or a new blockchain network node is added (primary path). The blockchain network node is set to "active" on the handheld device. All "active" nodes will be interconnected. The reliability of the newly added data is verified by consensus using the account importance algorithm (primary path expansion) and the data relevance algorithm (secondary path expansion). After consensus is achieved, the blockchain information expansion is completed, the data of the "active" nodes is updated, and the valve and pipe fitting full life cycle information management module actively accesses the data information of the "active" nodes, parses the node data, and automatically backs up the data information on the intranet server.

[0061] The blockchain information intelligent expansion mechanism module also includes a traceability module, which is embedded in the blockchain settings. Based on the problem data in the valve and pipe full life cycle information management module, the traceability module automatically tracks the physical address of the handheld scanning device and obtains the network node information corresponding to the problem data.

[0062] Furthermore, the traceability module includes a rapid traceability program that tracks the physical address of the handheld device based on the problem data in the valve and pipe fitting lifecycle information management module. This allows for quick tracking of the location of the problem on-site, obtaining the corresponding network node information, facilitating rapid processing of problem data, and greatly improving management efficiency.

[0063] The pipe and valve full life cycle information management module is configured to access the usage information of pipe and valve in the blockchain, and classify, statistically analyze and display the information on the webpage to provide pipe and valve information management.

[0064] The pipe and valve full lifecycle information management module includes an information entry module, an information statistics and query module, and a system settings module. These three modules are modularly designed on the main page. The information entry module is configured for processing information on pipe and valve entry and exit from the warehouse, manual entry of RFID tags, and modification and editing of pipe and valve information.

[0065] The information statistics and query module has four sub-modules: basic information query module, map area statistics module, life cycle statistics module, and inventory information query module, to meet users' query needs for pipe and valve information.

[0066] The system settings module is configured for user login, unit information management, user information management, permission management, and log management.

[0067] Furthermore, the system settings module is configured for key-based login, using the RSA algorithm and AES key to encrypt HTTPS protocol communication content. After data encryption, Base64 encoding is used, and before data decryption, Base64 decoding is used to ensure information security.

[0068] The system also includes a data retrieval module to embed the valve life warning module into the valve life information management module. For valves that meet the alarm conditions, alarm information will be generated in real time and displayed in the form of a floating window. Users can click on the floating window to view the detailed information of the alarmed valve.

[0069] Preferably, the valve and pipe fitting lifecycle information management module will periodically and proactively access the blockchain "active" node information, parse the node data, and update the web page.

[0070] Preferably, the pipe and valve fitting full life cycle information management module supports installation on PC and mobile APP, and the data is synchronized between the two.

[0071] Further refer to the appendix Figure 4 This is a schematic diagram of the main page of a specific embodiment of the pipe and valve full life cycle information management module of the present invention, showing its main functional modules and their distribution. From left to right, they are the system menu area, map display area and information notification area.

[0072] The system menu area mainly includes key functions such as information entry, information statistics query, and system settings. Information entry includes equipment warehousing, equipment outbound, equipment maintenance, and equipment scrapping. The equipment warehousing unit is submitted by the warehouse manager scanning the equipment label with a handheld device in the warehouse, where the equipment's factory information can be edited. The equipment outbound unit is also submitted by the warehouse manager scanning the equipment label with a handheld device in the warehouse, and the outbound time is automatically recorded by the information management system. The equipment maintenance and equipment scrapping units are submitted by the warehouse manager scanning the labels of the pipes and valves to be maintained and scrapped with a handheld device in the warehouse.

[0073] The information statistics and query system includes modules such as basic map area statistics, lifecycle statistics, inventory information query, items pending maintenance, items pending scrapping, warehouse management, equipment type, equipment information, mobile terminal, and grouping information. The map area statistics module modularizes the map display area into the system menu, offering similar functionality. The lifecycle statistics module is divided into statistics and icon displays of the lifespan of the same type of pipe and valve components from different manufacturers, as well as statistics and icon displays of the lifespan of the same type of pipe and valve components under different usage environments. The inventory information query module provides statistics on all pipe and valve components that are in stock, in use, under maintenance, scrapped, or lost, facilitating user access to relevant information. The items pending maintenance module compiles and organizes the automatically generated items pending maintenance. The warehouse management module maintains and manages the warehouse information used in the system. The equipment type module allows users to manage the system's equipment information. The system manages and categorizes the types of pipe fittings used, typically including valves, elbows, and high-pressure manifolds. The equipment information unit maintains basic information about the pipe fittings, such as equipment name, type, model, inner diameter, and outer diameter, but does not include manufacturer information; manufacturer information is selected during inventory entry. The mobile terminal unit manages handheld scanning devices used in the field, enhancing data transmission security during network communication between the system and field equipment. Verification is performed using a key and the handheld scanning device's serial number; only verified handheld devices can connect to the system for data communication. The grouping information unit integrates grouping information into the management system. Users scan RFID tags in batches using handheld devices, simultaneously inputting the same usage information for each device, facilitating data entry. The system settings mainly include modules such as unit management, user management, role management, permission management, and operation logs. The unit management unit mainly maintains the internal structure information of the unit, using a tree structure that can be added up to an unlimited number of levels. The user management unit mainly maintains system user information; by inputting a randomly generated key, users can log in to the PC, APP, and handheld scanning device. The role management unit is mainly used for maintaining role information in the system, such as setting roles like super administrator, warehouse manager, and site manager. Different roles have different permissions and can access different functional areas of the system. The permission management unit corresponds to the role management unit and is used to set functional permissions for accessing the system, which can be used by roles. The operation log unit is mainly used to generate records of all operations performed by users when logging into the system, including the time.

[0074] The map display area mainly shows a map of China and whether there are any pipe valves in use in each province. The province where the pipe valve is located is marked with a red dot. Clicking on a province will take you to view detailed information about the pipe valve in that province.

[0075] The information notification area primarily generates a notification directory to display in real-time the pipe and valve components that have triggered maintenance or scrapping conditions during use. Information about pipe and valve components triggering real-time alarms is displayed as a floating window on the main interface.

[0076] The valve lifespan early warning module is configured to be integrated into the valve lifespan information management module, used to acquire abnormal usage status of valves in real time and generate early warning information. Specifically, in this invention, the valve lifespan early warning module (i.e., valve lifespan early warning management) mainly parses blockchain node data information, performs identification, statistics, and classification display, while simultaneously monitoring the valve lifespan status in real time and quickly tracking the lifespan information of problematic valves.

[0077] Further refer to the appendix Figure 5 The pipe and valve life warning module includes a pipe and valve life prediction model and a pipe and valve classification model. The pipe and valve life prediction model calculates the used life of the pipe and valve by calling the life history information of the pipe and valve. The pipe and valve classification model determines the usage status of the pipe and valve based on the used life of the pipe and valve, including normal use, maintenance and repair, and life warning.

[0078] Among them, the pipe and valve life prediction model is a model built based on big data; the pipe and valve classification model is a model built based on life loss rate.

[0079] The process of constructing a life prediction model for pipe and valve components includes: firstly, dividing the existing data samples into a training set, a validation set, and a prediction set. The training set samples are used to train the neural network prediction model, the validation set samples are used to verify the accuracy of the neural network prediction model, and the prediction set samples are used to predict and analyze the life of pipe and valve components.

[0080] The pipe and valve life early warning module calculates the wall thickness loss of the pipe and valve through the life prediction model module based on the real-time operating parameters transmitted from the site. It calculates the current wall thickness of the pipe and valve and then compares it with the measured wall thickness value on site. The module uses the value with the smaller remaining wall thickness to issue an early warning. At the same time, the life prediction model will be updated regularly based on real-time traditional data from the site to ensure the accuracy of the prediction of the maximum erosion rate and wall thickness loss of the pipe and valve.

[0081] Preferably, the life prediction model for pipe and valve components is a neural network model built on big data. The data source includes existing actual working condition data, indoor experimental test data, and real-time updated data from the server. The extensive basic data ensures the accuracy and reliability of the life prediction model.

[0082] Preferably, in order to improve the safety boundary of pipe and valve components in field use, in the pipe and valve component classification model, the ratio of the used time of the pipe and valve component to the preset use time is δ. When δ≥95%, the pipe and valve component life warning module issues an alarm signal, and the corresponding pipe and valve component is immediately stopped from use; when 80%≤δ<95%, the pipe and valve component life warning module classifies the corresponding pipe and valve component into the maintenance module; when δ<80%, it is determined that the corresponding pipe and valve component is in normal use.

[0083] This invention utilizes a handheld scanning device to sense RFID tags on pipes and valves, and writes the usage data of the pipes and valves into a blockchain to achieve distributed storage of the usage information of the pipes and valves. The information of the "active" nodes in the blockchain is actively accessed by the pipe and valve full life cycle information management module, which automatically generates management records to prevent malicious data tampering and realizes networked management of the life cycle of pipes and valves. At the same time, a pipe and valve life early warning model is built based on big data to provide real-time alarms for pipes and valves with potential safety hazards during use, ensuring the safety of oil and gas construction sites.

[0084] The disclosed solution of this invention includes a blockchain-based RFID data network system (i.e., a data acquisition module), a blockchain information intelligent expansion mechanism module, a pipe and valve full lifecycle information management module, and a pipe and valve lifespan early warning module. The blockchain-based RFID data network system identifies RFID tags using handheld scanning devices and writes pipe and valve usage information into the blockchain, achieving distributed storage of pipe and valve full lifecycle data. The blockchain information intelligent expansion mechanism module is a dual-path blockchain network. The main path expands the blockchain information corresponding to the increase in the number of handheld devices, and the auxiliary path expands the blockchain information corresponding to the information entered by the handheld devices. The intelligent expansion mechanism also has intelligent consensus of network nodes, node silence / activity settings, and information traceability functions. The pipe and valve lifespan early warning module includes a lifespan prediction model built based on large data volumes and a pipe and valve classification model built based on lifespan loss rates, integrated into the pipe and valve information management system to achieve real-time early warning from the management platform. The information management system is used to access the distributed storage information of pipe and valves, and to statistically manage, classify, display, and provide real-time early warnings for pipe and valve usage information. This invention can effectively ensure the security of pipe and valve data transmission, improve the efficiency of pipe and valve management, and ensure the safety of pipe and valves in field use.

[0085] The second aspect of the present invention discloses a high-pressure pipe valve information management method based on a dual-path extended blockchain. The method is based on the high-pressure pipe valve information management system based on a dual-path extended blockchain as described above, and includes the following steps: Step S100, the data acquisition module collects the on-site usage data information of the pipe valve and transmits the data information to the blockchain information intelligent extension mechanism module for storage in the blockchain network node.

[0086] When an electronic tag is damaged, a new electronic tag is bound to the system according to the device number, and the original device usage information is saved. The RFID tag is identified by a handheld scanning device to enter, edit and view the usage information of pipe valves.

[0087] In step S200, the blockchain information intelligent expansion mechanism module stores the RFID data information identified by the handheld scanning device to the corresponding blockchain network node for distributed storage of valve usage data.
