Description

Technical Field

[0001] The present invention belongs to the technical field of natural gas membrane tank monitoring, and in particular relates to a method for monitoring an insulation system of an LNG membrane tank based on blockchain technology. Background Art

[0002] In recent years, the country has vigorously developed intelligent construction such as digital economy and smart transportation. In response to the national call, my country's ports are moving towards intelligence, automation and wisdom. Many new technologies are gradually being introduced into the construction of smart ports. AI and image recognition technologies have made initial progress in the construction of smart ports.

[0003] Liquefied natural gas is a major type of hazardous chemical cargo in world trade, and its trade volume is huge around the world. Existing port liquefied natural gas storage methods are mostly tank storage. Traditional oil storage tanks only have a single storage function and lack corresponding monitoring measures. In addition to having a more reasonable structure, the emerging liquefied natural gas membrane tank also has a corresponding temperature and gas leakage monitoring system in its insulation structure layer, which can effectively monitor the status of the storage tank in real time to avoid gas leakage or natural gas explosion caused by excessive temperature. However, the existing membrane tank monitoring system still has the following problems:

[0004] 1. Existing LNG membrane tank monitoring systems are centralized systems that lack robustness and have single-point failure problems. When a component or assembly in the system fails, the entire system will stop operating or significantly reduce performance.

[0005] 2. The existing liquefied natural gas membrane tank monitoring system lacks security, and the key data in the system is vulnerable to attack and tampering.

[0006] As an emerging distributed ledger technology, blockchain technology has the characteristics of decentralization, immutability, transparency and security. It can realize automated operations when combined with smart contract technology, which can greatly ensure the security of port-related data and promote the construction of smart ports.

[0007] Therefore, the present invention designs a monitoring method for an LNG membrane tank insulation system based on blockchain technology. Summary of the invention

[0008] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a LNG membrane tank insulation system monitoring method based on blockchain technology, so as to utilize the decentralization, immutability, transparency and other characteristics of blockchain to solve the problems existing in the existing membrane tank monitoring system, and combine with smart contract technology to realize the automation and intelligence of the entire system.

[0009] The present invention solves the technical problem by the following technical solutions:

[0010] A method for monitoring an LNG membrane tank insulation system based on blockchain technology, the method comprising the following steps:

[0011] S1. Build a blockchain network based on blockchain technology;

[0012] 1) All operations during the monitoring process will be carried out in the blockchain network;

[0013] 2) The environmental data collected in the insulation system will be uploaded to the blockchain network for preprocessing and storage, and the technicians will also call the monitoring data in the blockchain network;

[0014] S2, based on S1, write smart contracts for data processing and calling and deploy them in blockchain network nodes;

[0015] 1) The pre-processing smart contract will perform threshold analysis on the collected environmental data, and environmental data that exceeds the threshold range will be marked;

[0016] 2) Calling smart contracts to call data stored on the blockchain;

[0017] 3) The permission information smart contract is used to limit the usage permissions of the front-end application;

[0018] S3, after the smart contract based on S2 is deployed on the blockchain network node, the front-end application is built;

[0019] 1) The front-end application is used to visualize the environmental data uploaded to the blockchain in real time;

[0020] 2) The front-end application will provide data query functionality.

[0021] Moreover, the blockchain network includes a data acquisition module, a blockchain network module and a monitoring module connected in sequence;

[0022] The data acquisition module is used to detect the environment of each monitoring point in the LNG film tank to obtain environmental data, and bind the acquired environmental data with the corresponding monitoring point information and detection time to generate an environmental data packet and send it to the blockchain network module;

[0023] The blockchain network module is used to receive a request from the monitoring module and transmit the preprocessed LNG membrane tank environmental data corresponding to the acquisition request or the authority information data corresponding to the acquisition request according to the request.

[0024] Moreover, the blockchain network module includes several blockchain network nodes and the corresponding environmental data processing modules, permission modules and blockchain data copies connected thereto.

[0025] The blockchain network module is used to receive a request from a data acquisition module or a monitoring module, and send the request to a blockchain network node. Several blockchain network nodes process and endorse the request. When most of the blockchain network nodes in the blockchain network module endorse the request, the blockchain network module sends the endorsed response to the data acquisition module or the monitoring module.

[0026] The blockchain network node is used to call the environment data processing module or the authority module through the request information after receiving the request from the data acquisition module and the monitoring module;

[0027] The blockchain network node is used to store a copy of the blockchain data and to verify the blockchain data with other blockchain network nodes.

[0028] Moreover, the environmental data processing module is used to preprocess the environmental data acquired by the data acquisition module, and upload the preprocessed data to the blockchain for distributed storage. At the same time, the environmental data processing module receives the request of the monitoring module and acquires the preprocessed LNG membrane tank environmental data corresponding to the acquisition request from the blockchain and sends it to the monitoring module.

[0029] Moreover, the permission module is used to create permission information for the user to access the monitoring module, and upload the corresponding permission information to the blockchain for distributed storage, and after receiving the access request, the permission module is used to obtain the permission information corresponding to the access request from the blockchain and perform permission verification.

[0030] Furthermore, the monitoring module is used to obtain the user's authority information, and generate an access verification request based on the obtained user's authority information and send it to the authority module for authority verification;

[0031] The monitoring module directly connects and interacts with one of the blockchain network nodes in the blockchain network module. When the blockchain network node fails or malfunctions, the monitoring module connects and interacts with other blockchain network nodes.

[0032] The monitoring module is used to periodically send an acquisition request to the environmental data processing module, and perform visualization processing after receiving the LNG film tank environmental data preprocessed in accordance with the acquisition request;

[0033] The monitoring module is used to send an acquisition request to the environmental data processing module, and perform list processing after receiving the LNG film tank environmental data corresponding to the acquisition request.

[0034] The advantages and beneficial effects of the present invention are:

[0035] 1. The present invention uses blockchain technology to effectively improve the robustness of the existing LNG membrane tank insulation system monitoring system and can effectively prevent single point failures.

[0036] 2. The present invention uses blockchain technology to effectively improve the security of the existing LNG membrane tank insulation system monitoring system and can effectively prevent data tampering. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The monitoring module (3) directly interacts with one of the blockchain network nodes (201) in the blockchain network module (2). When the blockchain network node fails or malfunctions, the monitoring module (3) will connect and interact with other blockchain network nodes.
