[0002] In recent years, hydrogen energy has been rapidly promoted in the transportation sector due to its advantages such as high energy density, fast refueling speed, and environmental friendliness. It is often used in vehicles, ships, drones, and other fields, which has led to an increasing demand for hydrogen refueling from various operators and individual users. To ensure the safety of the public and users, it is necessary to supervise and dynamically track hydrogen cylinders in use. Currently, hydrogen cylinder tracking often uses 4G modules for location tracking. However, shared operators or individual users may need to replace these cylinders with cheaper ones that don't meet national standards. Therefore, this paper presents a dynamic monitoring and management method and system for hydrogen cylinder applications. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide a dynamic monitoring and management method and system for hydrogen cylinder applications.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dynamic monitoring and management method for hydrogen cylinder applications, the method comprising: Step S1: Based on the production data of the hydrogen cylinders, construct a digital twin model of the hydrogen cylinders and associate it with physical attributes; achieve synchronous mapping of the digital twin model of the hydrogen cylinders by collecting the status data of the hydrogen cylinders in real time. Step S2: Based on the real-time collected status data of the hydrogen cylinder, automatically verify the status of the hydrogen cylinder digital twin model; based on the filling parameters and status of the hydrogen cylinder, generate a digital report on filling stress analysis of the normal hydrogen cylinder status. Step S3: Construct a digital twin dynamic monitoring platform, import the digital twin model of the hydrogen cylinder into the digital twin dynamic monitoring platform, monitor the hydrogen cylinder dynamically in real time, and record the transportation trajectory; Step S4: Generate a unique digital twin hash value based on the hydrogen cylinder digital twin model, and associate it with the corresponding hydrogen cylinder production information to generate a corresponding anchor hash value; write the transportation trajectory into the corresponding blockchain according to the timestamp to form an on-chain electronic fence, and import the on-chain electronic fence into the digital twin dynamic monitoring platform to generate a traceable digital certificate; generate a filling transaction block based on the hydrogen cylinder filling parameters, filling stress analysis digital report, operator ID, and filling station qualifications; write the anchor hash value, digital certificate, and filling transaction block into the corresponding blockchain to prevent data tampering; Step S5: Based on the blockchain smart contract, set access permissions for different entities, thereby accessing data in the corresponding blockchain and saving access records in the corresponding blockchain; Step S6: Based on the status data of hydrogen cylinders collected in the historical period, construct a status assessment model, and then generate a life prediction report for the corresponding hydrogen cylinder. Based on the life prediction report, make a judgment and implement the corresponding treatment plan for the corresponding hydrogen cylinder.

[0005] Furthermore, the process of constructing a digital twin model of the hydrogen cylinder based on its production data and associating it with its physical attributes includes: Production data for the hydrogen cylinder is extracted from the database of the hydrogen cylinder manufacturer. This production data is then imported into professional 3D modeling software to construct a 3D geometric model of the hydrogen cylinder according to the actual scale. The differences in wall thickness distribution and weld locations are precisely marked in the model. Physical properties are obtained from the design documents of the hydrogen cylinder and then associated and bound to the constructed 3D geometric model. This ensures that the digital twin model not only has geometric features but also reflects its mechanical and safety performance boundaries, forming a complete digital twin model of the hydrogen cylinder.

[0006] Furthermore, the process of synchronously mapping the digital twin model of the hydrogen cylinder by collecting its status data in real time includes: Corresponding sensors are installed at appropriate locations on the hydrogen cylinder. These sensors transmit the collected status data to a data gateway in real time via wired or wireless communication modules. The data gateway performs preliminary processing on the received status data and transmits the processed data to the digital twin model of the hydrogen cylinder via the network. The real-time collected status data of the hydrogen cylinder is matched with the corresponding parameters in the digital twin model. Through this real-time data-driven approach, the digital twin model of the hydrogen cylinder is synchronously mapped to the physical hydrogen cylinder in terms of geometric shape and status parameters.

[0007] Furthermore, based on real-time collected status data of the hydrogen cylinders, the digital twin model of the hydrogen cylinders is automatically verified to check the status of the hydrogen cylinders; the process of generating a digital report on filling stress analysis of normal hydrogen cylinder status based on the filling parameters and status of the hydrogen cylinders includes: The hydrogen cylinder digital twin model has a built-in state verification algorithm. If all the real-time collected state data passes the verification of the state verification algorithm and the change trend of each parameter is stable, the corresponding hydrogen cylinder digital twin model determines that the current state of the hydrogen cylinder is normal. If a certain state data does not meet the verification of the state verification algorithm, the corresponding hydrogen cylinder digital twin model will automatically mark the abnormal state and issue an early warning. Obtain the actual filling parameters of the hydrogen cylinder, and combine them with the verification results of the hydrogen cylinder digital twin model; based on the hydrogen cylinder digital twin model, obtain the corresponding stress analysis results, and organize the stress analysis results, filling parameters and verification results into a structured digital report to form a filling stress analysis digital report for a normal hydrogen cylinder.

[0008] Furthermore, the process of building a digital twin dynamic monitoring platform includes: By integrating hardware and software resources and adopting a distributed architecture design, and using encryption technology, a digital twin dynamic monitoring platform is constructed.

The digital twin model of the hydrogen cylinder is then uploaded to the platform and deployed. At the same time, a unique identifier is established between the digital twin model of the hydrogen cylinder and the corresponding physical hydrogen cylinder. The digital twin dynamic monitoring platform receives real-time status data and pushes it to the hydrogen cylinder digital twin model in real time, driving the model to dynamically update on the platform's interface and display the cylinder's status in a three-dimensional visualization. Simultaneously, the platform acquires real-time transportation location information, records latitude and longitude and speed by timestamp, and associates these with the corresponding hydrogen cylinder identifier, drawing the transportation trajectory in real-time on the platform's electronic map.

[0010] Furthermore, the process of generating a unique digital twin hash value based on the hydrogen cylinder digital twin model, and associating it with the corresponding hydrogen cylinder's production information, thereby generating a corresponding anchor hash value, includes: The SHA-256 cryptographic hash algorithm is used to perform hash calculations on the core data of the hydrogen cylinder digital twin model. The hash value obtained after the calculation is the unique digital twin hash value. Production information of the corresponding physical hydrogen cylinders is collected, and the production information is combined with the generated digital twin hash value to form a related dataset containing key information of both. Based on the hash algorithm, the related dataset is encrypted to generate a new hash value, which is the anchor hash value.

[0011] Furthermore, the process of writing the transportation trajectory into the corresponding blockchain according to timestamps to form an on-chain electronic fence, and importing the on-chain electronic fence into the digital twin dynamic monitoring platform to automatically mark abnormal transportation status and generate traceable digital credentials includes: The digital twin dynamic monitoring platform organizes the transportation records of hydrogen cylinders according to timestamps and uploads the transportation records in batches to the preset blockchain system. The blockchain system verifies each transportation record and writes it into a block. The blocks are linked by hash values ​​to form an immutable chain structure. These continuous trajectory data constitute the on-chain electronic fence of the hydrogen cylinder transportation path on the blockchain. The digital twin dynamic monitoring platform reads the on-chain electronic fences written to the blockchain system, compares and analyzes them with the preset transportation planning routes, and obtains the abnormal or normal transportation status. It integrates the on-chain electronic fences, the abnormal or normal transportation status, and the timestamp to generate electronic documents that record the entire transportation trajectory and explain the abnormal situation. Through the hash verification mechanism of the blockchain system, a traceable digital certificate is formed.

[0012] Furthermore, the process of generating a filling transaction block based on the hydrogen cylinder filling parameters, filling stress analysis digital report, operator ID, and filling station qualifications includes: The filling parameters, filling stress analysis digital report, operator ID, and filling station qualifications of the corresponding hydrogen cylinders are organized according to the preset data structure. The organized data is then verified to check for missing information or format errors. After verification, the organized data is packaged into an independent transaction block, namely the filling transaction block, according to the blockchain transaction block generation rules.

[0013] Furthermore, based on blockchain smart contracts, the process of setting access permissions for different entities to access data in the corresponding blockchain and saving access records in the corresponding blockchain includes: Deploy blockchain smart contracts in a blockchain system, predefine different subject types, and set corresponding accessible blockchain data ranges; the blockchain smart contract sets an access permission verification mechanism to verify the submitted identity information, confirm the subject type and corresponding access permissions; after successful verification, the blockchain smart contract allows the subject type to access data within its permission range, and automatically records relevant information about the access behavior, writing the relevant information into the blockchain in real time to form an immutable access record.

[0014] Furthermore, the process of constructing a state assessment model includes: Acquire status data of hydrogen cylinders from several historical data collection periods; group and label these data sets as follows: It is a natural number; Will Several sets of historical data collection periods on the status of hydrogen cylinders were used as sample data, and Less than The natural numbers, and using the sample data, the mean of the sample data is obtained, denoted as the sample set; The status data of hydrogen cylinders from several historical collection cycles in the remaining groups are used as the test set; a training sample set is formed based on the sample set and the test set; a standard evaluation model is constructed based on convolutional neural networks; and the training sample set is input into the standard evaluation model to train the standard evaluation model, thereby obtaining the standard evaluation model after training, and the standard evaluation model after training is recorded as the state evaluation model. Based on the state assessment model, a life prediction report for the corresponding hydrogen cylinder is generated. Based on the life prediction report, a judgment is made and a corresponding treatment plan is implemented for the corresponding hydrogen cylinder.

[0015] The second aspect of the present invention also provides a dynamic monitoring and management system for hydrogen cylinder applications, including: a digital twin modeling module, a digital twin simulation module, a digital twin tracking module, a blockchain identity anchoring module, a blockchain traceability module, a blockchain evidence storage module, a blockchain sharing module, and a status assessment module. The digital twin modeling module constructs a digital twin model of the hydrogen cylinder based on the production data of the hydrogen cylinder and associates it with physical attributes; it achieves synchronous mapping of the digital twin model of the hydrogen cylinder by collecting the status data of the hydrogen cylinder in real time. The digital twin simulation module automatically verifies the state of the hydrogen cylinder based on real-time collected state data of the hydrogen cylinder digital twin model; and generates a digital report on filling stress analysis of a normal hydrogen cylinder state based on the filling parameters and state of the hydrogen cylinder. The digital twin tracking module is used to build a digital twin dynamic monitoring platform. The digital twin model of the hydrogen cylinder is imported into the digital twin dynamic monitoring platform to monitor the hydrogen cylinder in real time and record the transportation trajectory.

The blockchain traceability module is used to write the transportation trajectory into the corresponding blockchain according to the timestamp, forming an on-chain electronic fence, and importing the on-chain electronic fence into the digital twin dynamic monitoring platform to automatically mark the abnormal transportation status and generate traceable digital certificates. The blockchain evidence storage module generates a filling transaction block based on the filling parameters of the hydrogen cylinder, the digital report of filling stress analysis, the operator ID, and the filling station qualification; the anchor hash value, digital certificate, and filling transaction block are written into the corresponding blockchain to prevent data tampering. The blockchain sharing module, based on blockchain smart contracts, sets access permissions for different entities, thereby allowing them to access data in the corresponding blockchain and save access records in the corresponding blockchain. The status assessment module constructs a status assessment model based on the status data of hydrogen cylinders collected over historical periods, and then generates a lifespan prediction report for the corresponding hydrogen cylinder. Based on the lifespan prediction report, it makes a judgment and executes the corresponding treatment plan for the corresponding hydrogen cylinder.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This application achieves real-time mapping between the physical entity of the hydrogen cylinder and its virtual model. Combined with blockchain technology, it ensures the security and traceability of data throughout the entire lifecycle. This not only improves the accuracy and timeliness of hydrogen cylinder status monitoring, helping to identify potential safety hazards in advance, but also optimizes the efficiency of the entire process management of hydrogen cylinders from production to disposal by standardizing data management and sharing mechanisms, enhancing collaborative trust among all participating entities. Simultaneously, the status assessment model built based on historical data can provide a scientific basis for hydrogen cylinder lifespan prediction and maintenance, reducing resource waste and further ensuring the safety and economy of hydrogen cylinder application.

Step S3: Construct a digital twin dynamic monitoring platform, import the digital twin model of the hydrogen cylinder into the digital twin dynamic monitoring platform, monitor the hydrogen cylinder dynamically in real time, and record the transportation trajectory; Step S4: Generate a unique digital twin hash value based on the hydrogen cylinder digital twin model, and associate it with the corresponding hydrogen cylinder production information to generate a corresponding anchor hash value; write the transportation trajectory into the corresponding blockchain according to the timestamp to form an on-chain electronic fence, and import the on-chain electronic fence into the digital twin dynamic monitoring platform to generate a traceable digital certificate; generate a filling transaction block based on the hydrogen cylinder filling parameters, filling stress analysis digital report, operator ID, and filling station qualifications; write the anchor hash value, digital certificate, and filling transaction block into the corresponding blockchain to prevent data tampering; Step S5: Based on the blockchain smart contract, set access permissions for different entities, thereby accessing data in the corresponding blockchain and saving access records in the corresponding blockchain; Step S6: Based on the status data of hydrogen cylinders collected in the historical period, construct a status assessment model, and then generate a life prediction report for the corresponding hydrogen cylinder. Based on the life prediction report, make a judgment and implement the corresponding treatment plan for the corresponding hydrogen cylinder.

[0023] It should be further explained that, in the specific implementation process, the process of constructing a digital twin model of the hydrogen cylinder based on the production data of the hydrogen cylinder and associating it with physical attributes includes: Optionally, in this embodiment of the application, the production data of the hydrogen cylinder is extracted from the database of the hydrogen cylinder manufacturer. The production data includes, but is not limited to, three-dimensional dimensions, material parameters, wall thickness distribution data, and weld location.

[0024] It should be noted that the above three-dimensional dimensions are obtained through design drawing parameters or 3D scanning data recorded during the production process, including but not limited to bottle height, diameter, and bottle mouth size; the above material parameters include but are not limited to the grade, yield strength, tensile strength, and elongation of the metal material used, which can be extracted from the material certificate or production records; the above wall thickness distribution data are obtained by detecting different positions of the bottle (such as the bottle body, bottle bottom, and neck transition) during the production process using dedicated wall thickness detection equipment, forming a wall thickness distribution map; the above weld positions are determined according to the welding process records, including but not limited to the specific coordinates and dimensions of circumferential welds and longitudinal welds.

[0025] Optionally, in this embodiment, the production data is imported into professional 3D modeling software to construct a 3D geometric model of the hydrogen cylinder according to the actual scale. The differences in wall thickness distribution and weld locations are precisely marked in the model. Physical properties are obtained from the hydrogen cylinder's design files and linked to the constructed 3D geometric model. This ensures that the digital twin model not only possesses geometric morphological features but also reflects its mechanical and safety performance boundaries, forming a complete digital twin model of the hydrogen cylinder.

[0026] It should be noted that the above physical properties include, but are not limited to, design pressure, burst pressure, and fatigue life curve; the design pressure and burst pressure are determined based on product design standards and burst test results; the fatigue life curve is generated by fitting the fatigue test data of the material and the operating conditions of the hydrogen cylinder (such as the number of filling and discharging cycles).

[0027] It should be further explained that, in the specific implementation process, the process of synchronously mapping the digital twin model of the hydrogen cylinder by collecting real-time status data of the hydrogen cylinder includes: Optionally, in this embodiment, corresponding sensors are installed at appropriate locations on the hydrogen cylinder. These sensors transmit the collected status data to a data gateway in real time via wired or wireless communication modules. The data gateway performs preliminary processing on the received status data, including filtering (removing signal noise), format conversion (unifying data format), and verification (ensuring data integrity). The processed data is then transmitted via network to the digital twin model of the hydrogen cylinder. The real-time collected status data of the hydrogen cylinder is matched with the corresponding parameters in the digital twin model. Through this real-time data-driven approach, the digital twin model of the hydrogen cylinder maintains consistency with the physical hydrogen cylinder in terms of geometry and status parameters, achieving synchronous mapping between the two and intuitively reflecting the current state of the physical cylinder.

[0028] It should be noted that the above-mentioned sensor settings include, but are not limited to, installing pressure sensors inside the bottle or at the bottle opening to collect real-time pressure data, installing temperature sensors on the bottle surface to monitor the bottle temperature, and installing vibration sensors in the middle of the bottle to capture vibration signals during transportation or use.

[0029] To further explain, real-time pressure data is assigned to the pressure attribute in the digital twin model of the hydrogen cylinder; real-time temperature data is assigned to the temperature attribute in the digital twin model of the hydrogen cylinder; and real-time vibration data is assigned to the vibration attribute in the digital twin model of the hydrogen cylinder.

[0030] It should be further explained that, in the specific implementation process, the hydrogen cylinder status is automatically verified based on the real-time collected status data of the hydrogen cylinder digital twin model; the specific process of generating a digital report on filling stress analysis of a normal hydrogen cylinder status based on the filling parameters and status of the hydrogen cylinder includes: Optionally, in this embodiment of the application, the digital twin model of the hydrogen cylinder has a built-in state verification algorithm. If all the real-time collected state data passes the verification of the state verification algorithm and the change trend of each parameter is stable, the corresponding digital twin model of the hydrogen cylinder determines that the current state of the hydrogen cylinder is normal. If a certain state data does not meet the verification of the state verification algorithm, the corresponding digital twin model of the hydrogen cylinder will automatically mark the abnormal state and issue an early warning.

[0031] It should be noted that the above-mentioned state verification algorithm calls the real-time collected state data and compares it with the preset safety threshold range in the digital twin model of the hydrogen cylinder; the safety threshold includes, but is not limited to, the normal operating pressure range, the allowable temperature fluctuation range, and the maximum vibration acceleration limit.

[0032] Optionally, in this embodiment, the filling parameters of the actual hydrogen cylinder are obtained. These filling parameters include, but are not limited to, the purity of the hydrogen being filled, the initial filling pressure, the filling rate, and the target pressure. Simultaneously, the verification results of the hydrogen cylinder are combined with the digital twin model of the hydrogen cylinder. Based on the mechanical analysis module in the digital twin model, the corresponding stress analysis results are obtained. The stress analysis results, filling parameters, and verification results are then compiled into a structured digital report, clearly indicating the stress distribution characteristics, safety assessment conclusions, and relevant calculation basis, thus forming a digital report on the filling stress analysis of a normal hydrogen cylinder.

[0033] It should be noted that the above-mentioned mechanical analysis module simulates the pressure transmission process inside the cylinder under the current filling parameters and verification results of the hydrogen cylinder, based on the three-dimensional dimensions, wall thickness distribution, and material parameters of the cylinder. It calculates the stress distribution in various parts of the cylinder (especially in areas with thinner walls and weld seams), analyzes whether the maximum stress value is within the safe bearing range of the material, and examines the stress change pattern during the filling process.

[0034] It should be further explained that, in the specific implementation process, the construction of the digital twin dynamic monitoring platform includes: Optionally, in this embodiment, constructing a digital twin dynamic monitoring platform requires integrating hardware and software resources. The digital twin dynamic monitoring platform architecture adopts a distributed architecture design. Based on the hardware and software resources and the distributed architecture design, the efficiency of data processing and the stability of the system are ensured, and encryption technology is used to guarantee the security of data transmission and storage. After the digital twin dynamic monitoring platform is built, debugging and optimization are performed to ensure that all modules work collaboratively and meet the functional requirements for dynamic monitoring of the entire lifecycle of hydrogen cylinders.

[0035] It should be noted that the aforementioned hardware resources include, but are not limited to, configuring high-performance servers for data processing and model operation, data storage devices for storing historical and real-time data, communication equipment, and display terminals for visualization. The aforementioned software includes, but is not limited to, a data access module (supporting multiple sensor data protocols to receive and parse real-time data), a digital twin model management module (responsible for loading, updating, version control, and driving the operation of the hydrogen cylinder digital twin model), a real-time monitoring module (for real-time processing, analysis, and display of hydrogen cylinder status data), a trajectory tracking module (integrating a GPS positioning interface to obtain transportation location information), an alarm module (setting multi-level alarm thresholds to trigger audible, visual, or information alarms in case of abnormalities), a blockchain interaction module (developing a data interface with the blockchain system to enable data uploading and querying), and a user management module (for platform user registration, permission allocation, and operation records).

[0036] It should be further explained that, in the specific implementation process, the process of importing the digital twin model of the hydrogen cylinder into the digital twin dynamic monitoring platform to dynamically monitor the hydrogen cylinder in real time and record its transportation trajectory includes: Optionally, in this embodiment of the application, the constructed digital twin model of the hydrogen cylinder is converted to a new format to adapt to the model import specifications of the digital twin dynamic monitoring platform. The digital twin model of the hydrogen cylinder is then uploaded to the digital twin dynamic monitoring platform and deployed through the digital twin model management module of the digital twin dynamic monitoring platform. At the same time, a unique identifier association is established between the digital twin model of the hydrogen cylinder and the corresponding physical hydrogen cylinder, thereby enabling real-time dynamic monitoring. It should be noted that the unique identifier association can be bound by the gas cylinder number or other unique features, and this application does not impose further limitations.

[0037] Optionally, in this embodiment, the data access module of the digital twin dynamic monitoring platform continuously receives real-time status data (pressure, temperature, vibration, etc.) from the hydrogen cylinder sensors and pushes this data to the hydrogen cylinder digital twin model in real time. This drives the hydrogen cylinder digital twin model to dynamically update on the digital twin dynamic monitoring platform interface, displaying the cylinder status in a three-dimensional visualization manner, such as using color changes to indicate temperature distribution, displaying real-time pressure through numerical overlay, and dynamically simulating vibration. Simultaneously, the trajectory tracking module of the digital twin dynamic monitoring platform communicates with the GPS or Beidou positioning device on the transport vehicle to obtain real-time transport location information, records latitude and longitude, travel speed, and other data by timestamp, and associates this data with the corresponding hydrogen cylinder identifier. The transport trajectory is then drawn in real-time on the electronic map of the digital twin dynamic monitoring platform, intuitively displaying the transport path and current location of the hydrogen cylinder, achieving full trajectory recording of the hydrogen cylinder transport process.

[0038] It should be further explained that, in the specific implementation process, the process of generating a unique digital twin hash value based on the aforementioned hydrogen cylinder digital twin model, and associating it with the corresponding hydrogen cylinder's production information, thereby generating the corresponding anchor hash value, includes: Optionally, in this embodiment of the application, the SHA-256 cryptographic hash algorithm is used to perform hash calculation on the core data of the hydrogen cylinder digital twin model. The hash value obtained after calculation is the unique digital twin hash value, which can uniquely identify the hydrogen cylinder digital twin model.

[0039] It should be noted that the aforementioned core data includes, but is not limited to, the three-dimensional geometric feature parameters (such as hash digests of key dimensions), material parameter set, physical property data (design pressure, burst pressure, etc.) and model version information of the digital twin model of the hydrogen cylinder.

[0040] Optionally, in this embodiment, production information of the corresponding physical hydrogen cylinder is collected, and the production information is combined with the generated digital twin hash value to form an associated dataset containing key information of both. Based on a hash algorithm, the associated dataset is encrypted to generate a new hash value, which is the anchor hash value. The anchor hash value is used to tightly link the digital twin model of the hydrogen cylinder with the production source information of the physical hydrogen cylinder, realizing a unique binding between the digital model and the physical entity.

[0041] It should be noted that the above production information includes, but is not limited to, production number, production date, manufacturer, production line number, and quality inspection report number.

[0042] It should be further explained that, in the specific implementation process, the process of writing the transportation trajectory into the corresponding blockchain according to the timestamp to form an on-chain electronic fence, and importing the on-chain electronic fence into the digital twin dynamic monitoring platform to automatically mark the abnormal transportation status and generate traceable digital credentials includes: Optionally, in this embodiment of the application, the trajectory tracking module of the digital twin dynamic monitoring platform organizes the transportation records of the hydrogen cylinder transportation trajectory according to the timestamp, and uploads the transportation records in batches to the preset blockchain system through the blockchain interaction module of the digital twin dynamic monitoring platform. The blockchain system verifies each transportation record and writes it into a block. Each block is associated with a hash value to form an immutable chain structure. These continuous trajectory data constitute the on-chain electronic fence of the hydrogen cylinder transportation path on the blockchain.

[0043] The digital twin dynamic monitoring platform reads the on-chain electronic fences written to the blockchain system and compares them with the preset transportation route. If the actual transportation trajectory exceeds the planned route or enters a restricted area, the digital twin dynamic monitoring platform automatically marks it as an abnormal transportation status and highlights the abnormal section and time on the monitoring interface. Simultaneously, the digital twin dynamic monitoring platform integrates the on-chain electronic fences, abnormal or normal transportation status, and timestamps to generate an electronic document recording the entire transportation trajectory and explaining any abnormalities (or marking it as normal if there are no abnormalities). The authenticity and integrity of this electronic document are ensured through the blockchain system's hash verification mechanism, forming a traceable digital certificate used to prove the transportation process of the hydrogen cylinders.

[0044] It should be noted that each of the above transportation records includes, but is not limited to, time information, latitude and longitude coordinates, vehicle identification, and corresponding hydrogen cylinder identification.

[0045] It should be further explained that, in the specific implementation process, the process of generating the filling transaction block based on the hydrogen cylinder filling parameters, filling stress analysis digital report, operator ID, and filling station qualifications includes: Optionally, in this embodiment, the filling parameters, filling stress analysis digital report, operator ID, and filling station qualification of the corresponding hydrogen cylinder are organized according to a preset data structure to ensure that the information is complete and the format is standardized. For example, the data is organized in the form of key-value pairs, and the meaning and corresponding value of each field are clearly defined. This application does not make further limitations in this regard.

[0046] The processed data is validated to check for missing information or format errors. Once the validation is successful, the processed data is packaged into an independent transaction block, i.e., a filling transaction block, according to the blockchain transaction block generation rules.

[0047] It should be noted that the qualifications of the aforementioned filling stations include, but are not limited to, the operating license number, validity period, qualification level, and recent audit results. Each filling transaction block contains a unique identifier for subsequent traceability.

[0048] The anchor hash value, digital certificate, and filling transaction block are written into the corresponding blockchain to prevent data tampering.

[0049] It should be further explained that, in the specific implementation process, based on blockchain smart contracts, the process of setting access permissions for different entities to access data in the corresponding blockchain, and saving access records in the corresponding blockchain includes: Optionally, in this embodiment, a blockchain smart contract is deployed in the blockchain system. Different subject types are predefined, and for each subject type, the scope of blockchain data it can access is clearly defined in the blockchain smart contract. Simultaneously, the blockchain smart contract sets up an access permission verification mechanism. When a subject type needs to access blockchain data, it must submit identity verification information (such as a digital certificate or account address) to the smart contract. The blockchain smart contract verifies the submitted identity information to confirm the subject type and its corresponding access permissions. After successful verification, the blockchain smart contract allows the subject type to access data within its permission scope and automatically records relevant information about the access behavior. This relevant information includes, but is not limited to, the identity identifier of the accessing subject type, the access time, the accessed data block number, and the accessed data type.
