Description

Technical Field

[0001] This application relates to the technical field of pump station safety environment, and particularly to a method and device for establishing a pump station safety control environment based on blockchain. Background Art

[0002] Currently, most pump stations still use a centralized network architecture. Data is stored in a centralized server and regularly managed and maintained. Records of operation and control instructions are mainly stored in the form of paper-based forms. Remote monitoring of pump stations transmits information through the Internet of Things, enabling the storage of pump station data and the execution of operation instructions for pump station units. However, the Internet of Things system is intricate, and data will pass through different carriers during the entire transmission process. The existing operation data security issues have attracted people's attention. Therefore, protecting the data security of the Internet of Things in the pump station control process has become particularly challenging.

[0003] The prior art has problems such as centralized network architecture, lack of application layer security, and insufficient product safety standardization. These problems lead to potential safety hazards in the data transmission and storage of pump station control systems. At the same time, the complexity of the Internet of Things also makes data pass through different carriers during the transmission process, resulting in data security problems. Protecting the data security of the Internet of Things has become particularly challenging. The centralized network architecture and centralized server make the internal network system of the pump station vulnerable to malicious attacks, and the data information in the database is easily leaked, threatening the data security and operation safety of the pump station. The form information storage of paper-based operation and control instruction records is prone to loss and damage, and it is difficult to trace the operation records, making the operation cumbersome and complex.

[0004] In summary, how to provide a secure solution for the transmission and storage of pump station operation data is an urgent problem to be solved currently. Summary of the Invention

[0054] The core of the present invention is to provide a method and device for establishing a pump station safety control environment based on blockchain, which can ensure the security of pump station operation data during transmission and storage, avoiding the risks of data leakage, tampering, or loss, through the distributed network architecture and digital signature algorithm of blockchain.

[0055] To enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0056] Please refer to Figure 1 , Figure 1 which is a flowchart of the first specific embodiment of a method for establishing a pump station safety control environment based on blockchain provided by the present invention; the specific operation steps are as follows:

[0057] Step S101: Use the elliptic curve digital signature algorithm to sign the information of the pump station control operation form and the pump station operation monitoring data, and authenticate the identity of the node uploading the data;

[0058] Create a double-chain structure for the pump station operation control blockchain;

[0059] Before deploying the blockchain network, register the identities of the monitoring device nodes and the pump station management platform nodes. After the nodes pass the legal authentication, authorize each node to generate its corresponding key pair;

[0060] The monitoring device uses its corresponding private key to generate signature information for the pump station operation data to be transmitted;

[0061] Receive the data to be transmitted and the signature information, and decrypt and verify the signature information based on the public key of the monitoring device.

[0062] Step S102: Construct a data block and securely store the data after authentication;

[0063] After ensuring the legality of the node identities and data information in the network, collect the pump station operation monitoring data and pump station control operation form data generated within a certain period of time;

[0064] Perform digital signature and verification on the pump station operation monitoring data and the pump station control operation form data, and temporarily store them in the local record pool in chronological order. When the size of the record pool is equal to the size of the block, pack the information into a block;

[0065] Construct a data block for the transaction information to form a chain structure, and record the operation condition information and operation record information in the blockchain for distributed storage, including:

[0066] Construct a chained block structure for transaction information. The block structure includes a block header and a block body. Each data block references the cryptographic hash value Prev-Hash of the previous block and stores it in the block header of the linked list, connecting the current new data block to the previous block to form a chained structure;

[0067] Add the block number Version of the current block in the chained block structure, the timestamp Timestamp indicating the creation time of the current block, the random number Nonce generated during the consensus process of the current block, the hash value Prev-Hash of the previous block, the cryptographic hash value Block Hash of the current block, and the Merkle root Merkle root generated through the hash process of the Merkle tree in the current block body to the block header of each data block. The hash value of the last block is saved in the system;

[0068] If any data in the blockchain is changed, the Hash value calculated by the block with data changes will be different from the Prev-Hash field saved in the next block;

[0069] Add the Merkle tree structure formed by hashing the transaction data records to the block body. Pair and perform hash operations on the transaction data records received within a certain period until a unique Merkle root is generated and recorded in the block header.

[0070] Step S103: Use the improved PBFT consensus algorithm to obtain the consistency consensus protocol of each node in the blockchain after secure storage, and record the data blocks that have completed consensus verification in the blockchain;

[0071] Based on the improved PBFT consensus algorithm, the authorized data acquisition terminal and the master node marked as the leader execute the consensus process, and other authorized nodes act as secondary nodes. The master node broadcasts its data block, timestamp and other information to the secondary nodes for verification and review. When all nodes reach a consistency consensus and believe that the new block can be added to the consortium chain, including:

[0072] Aggregate all the operation data monitored by the sensors uploaded by the master node into a new data block. The data block contains information such as the digital signature of the master node and the hash value of the block. The requesting end node sends a request message to all terminal nodes in the network to activate the service operation of the nodes;

[0073] After receiving the request, the master node sorts and stores multiple data information to be placed in the new block from the monitoring data uploaded by all sensors in a list, and broadcasts the list to all nodes in the entire blockchain network;

[0074] After each node receives the transaction list, it verifies and audits the integrity and legality of the transactions, adds the audit results to the digital signature of each node, and broadcasts them to other secondary nodes.

[0075] The master node is used to send the currently audited data block and the corresponding digital signature record to all authorized data acquisition terminal nodes for storage, and then store the data block in the blockchain network;

[0076] For the operation record information in the pump station control operation blockchain, the authorized pump station management platform node and the master node execute the consensus process. After verifying and reviewing the data block, it is added to the blockchain network for storage.

[0077] Step S104: Automatically analyze the running data in the blockchain through the deployment of smart contracts, detect abnormal data and faults, and trigger an alarm.

[0078] Based on the data transmitted by the monitored devices under its jurisdiction, the data acquisition terminal formulates smart contracts for each device respectively, modularizes and customizes the operation monitoring data and its response events, sets a preset threshold for the data acquisition terminal, analyzes the monitoring data based on the preset threshold, and for the running data exceeding the threshold, detects possible anomalies or faults, and triggers corresponding alarms or operations, which are sent to the pump station operation control platform for display.

[0079] This embodiment provides a method for establishing a pump station security control environment based on blockchain. Through the distributed network architecture and digital signature algorithm of the blockchain, it can ensure the security of pump station operation data during transmission and storage, and avoid the risks of data leakage, tampering or loss. Compared with the centralized network architecture of competing products, this technology can more effectively protect sensitive data, enhance the security of the product, and use the improved PBFT consensus algorithm to solve the mutual trust problem between nodes in a decentralized system, ensuring the consistency and reliability of data. This feature helps to improve the trust between the pump station management platform and the data acquisition terminal, and while ensuring the accuracy and integrity of the data, it enhances the overall credibility of the product.

[0080] Based on the above embodiment, this embodiment describes the method for establishing a pump station security control environment based on blockchain, as Figure 2 shown, specifically as follows:

[0081] As Figure 3 shown, the elliptic curve digital signature algorithm is used to sign the information of the pump station control operation form and the pump station operation monitoring data, and authenticate the identity of the node uploading the data to ensure the legality of the node identity and data information in the blockchain; (Digital signature and identity authentication)

[0082] Create a double-chain structure for the operation control blockchain of the pumping station, including two consortium blockchains: the operation monitoring blockchain and the control operation blockchain;

[0083] Before deploying the blockchain network, register the identities of the monitoring device nodes and the pumping station management platform nodes. After the nodes are legally authenticated, authorize each node to generate its corresponding key pair, namely the private key and the public key, including:

[0084] Select a bilinear mapping e: G*G = GT, where G is an additive group, GT is a multiplicative group, and the generator is P. Select a Hash function H: {0,1}* → G;

[0085] The blockchain node randomly selects d in the unit group finite field Zq* of the prime modulus n, and d is the private key; randomly selects P in G* and calculates Q = Pd, and Q is the public key.

[0086] For the pumping station operation monitoring data information data to be transmitted, the monitoring device uses its own private key d to generate signature information (r, s), where r and s are authentication parameters, including:

[0087] Select a random number k in the interval [1, n - 1], where n is the order of G and n is a prime number, and G is the base point of the elliptic curve;

[0088] Calculate the curve point (x1, y2) = k*G;

[0089] Calculate the authentication parameter r = x1 mod n;

[0090] Use the hash function Hash() to calculate Hash(data), where data is the data information to be sent, and convert the obtained hash value into an integer e;

[0091] Calculate the authentication parameter s = k-1(e + rd) mod n, where d is the private key of the monitoring device, and obtain the signature information (r, s) of the data;

[0092] Upload the data data to be transmitted and the signature information (r, s) to the data acquisition terminal.

[0093] The data acquisition terminal receives the data to be transmitted and the signature information, decrypts the encrypted information using the public key of the monitoring device, and verifies its legality, including:

[0094] Check whether r and s are integers in the interval [1, n - 1];

[0095] Calculate e = Hash(data);

[0096] Calculate u1 = es-1 mod n and u2 = rs-1 mod n respectively;

[0097] Calculate the curve point (x1, y1) = u1*G + u2*Q, where Q is the public key of the monitoring device;

[0098] If (x1, y1) = 0, the signature is invalid; if r ≡ x1 (mod n), the signature is valid, otherwise it is invalid. If the verification is successful, upload the pump station operation monitoring data to the pump station management platform and the pump station operation monitoring blockchain.

[0099] Similarly, for the control operation form data (pump station operation records) of the pump station, the pump station management platform generates signature information using its private key. The management center accepts the corresponding data and signature information, decrypts the data using the public key of the management platform and completes its legality verification. After successful verification, upload the data information to the pump station control operation blockchain.

[0100] The data acquisition terminal and the pump station management platform collect transaction records within a certain period of time, including pump station operation monitoring data and pump station control operation form data respectively, and construct data blocks to securely store the data;

[0101] As Figure 4 shown, after ensuring the legality of the node identities and data information in the network, the data acquisition terminal and the pump station management platform respectively collect transaction records generated within a certain period of time after the generation of the previous block, namely pump station operation monitoring data and pump station control operation form data;

[0102] The data acquisition terminal and the pump station management platform perform digital signature and verification on the records, and temporarily store them in the local record pool in chronological order. When the size of the record pool is equal to the size of the block, the system packs the information into a block;

[0103] Construct a data block for the transaction information to form a chain structure, record the operating condition information and operation record information in the blockchain for distributed storage, and ensure the traceability and anti-tampering of the data information, including:

[0104] Construct a chain block structure for the transaction information. The block structure includes a block header and a block body. Each data block references the encrypted hash value Prev-Hash of the previous block and stores it in the block header of the linked list. Connect the current new data block to the previous block to form a chain structure. Therefore, the historical information of the data block can be traced through the value of Prev-Hash to verify the legality of the data block;

[0105] For the described block structure, add the version number Version of the current block, the timestamp Timestamp representing the creation time of the current block, the nonce Nonce generated during the consensus process of the current block, the hash value Prev-Hash of the previous block, the encrypted hash value Block Hash of the current block, and the Merkle root Merkle root generated through the hash process of the Merkle tree in the current block body to the block header of each data block. The hash value of the last block is saved in the system;

[0106] If any data in the blockchain is changed, the Hash value calculated for the block with data changes will be different from the Prev-Hash field saved in the next block, enabling the detection of data changes in the relevant block and finding the location of the corresponding block, thus achieving the feature of immutability;

[0107] Add the Merkle tree structure formed by hashing the transaction data records to the block body. The Merkle tree is a binary tree structure used to store transaction information and the number of transactions. Pair and perform hash operations on the transaction data records received within a certain period until a unique Merkle root is generated and recorded in the block header;

[0108] For the blockchain of pump station operation monitoring, the transaction information in the block body is the operation monitoring data of the pump station, specifically including information such as the type of monitoring equipment, the monitoring content, the operation monitoring data (data such as flow rate, head, blade angle, number of operating units, etc.), the monitoring time, the processing node, and the processing node signature;

[0109] For the blockchain of pump station control operations, the transaction information in the block body is the form data of the pump station control operations, specifically including information such as the operation number, operation task, operation item and sequence number, operation mark, the person issuing the order, the person receiving the order, the order time, the operator, the supervisor, the start and end times of the operation, the processing node, and the signature in the operation form;

[0110] Broadcast a data block constructed to the entire blockchain network. Nodes in other blockchain networks review and verify the transaction records in this block. If the block is verified successfully, the message records in the block will be added to the end of the main chain in a linear and chronological order and connected to the previous block.

[0111] As Figure 5 shown, use the improved PBFT consensus algorithm to obtain the consensus protocol of each participating node in the blockchain. After the data block is completed with consensus verification, it is recorded in the blockchain, solving the problem of mutual trust between nodes in the decentralized system;

[0112] Based on the improved PBFT consensus algorithm, the consensus process is executed by authorized data collection terminals and the primary node marked as the leader. Other authorized nodes act as secondary nodes. The leader broadcasts its data block, timestamp, and other information to the secondary nodes for verification and review, including:

[0113] Aggregate all the operation data monitored by sensors uploaded within the primary node into a new data block. The data block contains information such as the digital signature of the primary node and the hash value of the block. The requesting end node (i.e., the leader) sends a request message to all terminal nodes in the network to activate the service operation of the nodes;

[0114] After receiving the request, the primary node sorts and stores multiple data information to be placed in the new block from the monitoring data uploaded by all sensors in a list, and broadcasts the list to all nodes in the entire blockchain network;

[0115] After each node receives the transaction list, it verifies and audits the integrity and legality of the transaction, adds the audit result to the digital signature of each node, and broadcasts it to other secondary nodes. If a node receives information from 2f different nodes, it indicates that the preparation phase of the node has been completed;

[0116] For abnormal nodes, the maximum number of abnormal nodes that the system can tolerate is f (where n ≥ 3f + 1), and abnormal nodes cannot be broadcast;

[0117] The node receives and aggregates the audit results from other secondary nodes, and compares them with its own audit results. The secondary node broadcasts a confirmation message to other secondary nodes;

[0118] If both the primary node and the secondary nodes receive (n - f) identical confirmation request messages (including their own information), they send a feedback result to the client and write the result into the block.

[0119] The total number of nodes in the blockchain network is n, and the total number of abnormal nodes is f. For malicious or faulty abnormal secondary nodes that appear in the network, they generally do not respond to requests from other nodes;

[0120] All nodes reach a consensus and believe that the new block can be added to the consortium chain;

[0121] The leader sends the currently audited data block and the corresponding digital signature record to all authorized data collection terminal nodes for storage, and then stores the data block in the blockchain network;

[0122] The leader further analyzes the audit results of the nodes not approved in the system to determine whether these nodes are malicious, and promptly processes abnormal secondary nodes. For secondary nodes participating in the consensus, the pump station manager will maintain or reject abnormal secondary nodes based on the feedback results;

[0123] Similarly, for the operation record information in the pump station control operation blockchain, after the authorized pump station management platform nodes and the main node execute the consensus process and complete the verification and review of the data block, it is added to the blockchain network for storage.

[0124] As Figure 6 shown, by deploying smart contracts, the operation data is automatically analyzed, displayed on the pump station operation management platform, while detecting possible anomalies or faults and triggering corresponding alarms or operations.

[0125] The data acquisition terminal formulates smart contracts for each device according to the data transmitted by the jurisdiction monitoring devices, modularizing and customizing the operation monitoring data and its response events;

[0126] Set thresholds for the data acquisition terminal. Only the smart contract management party has the permission to upload data, and the created smart contract is uploaded to the pump station operation monitoring blockchain;

[0127] After the smart contract is deployed, it cannot be edited again. If the contract of the device needs to be updated and replaced, the original contract must be destroyed and a new contract must be deployed, without affecting the operation of other contracts;

[0128] The monitoring device uploads the pump station operation monitoring data to the data acquisition terminal through the wireless network, and the data acquisition terminal sends the data to the corresponding smart contract;

[0129] The smart contract analyzes the monitoring data according to the set thresholds. For the operation data exceeding the thresholds, it detects possible anomalies or faults and triggers corresponding alarms or operations;

[0130] Write the pump station operation monitoring data and analysis results into the operation monitoring blockchain, and send them to the pump station operation control platform for display and early warning.

[0131] A method for establishing a pump station safety control environment based on blockchain provided by an embodiment of the present invention can ensure the security of pump station operation data during transmission and storage through the distributed network architecture and digital signature algorithm of the blockchain, avoiding the risks of data leakage, tampering, or loss. Compared with the centralized network architecture of competing products, this technology can more effectively protect sensitive data and enhance the security of the product. By deploying smart contracts, real-time analysis of pump station operation data can be carried out to detect possible anomalies or faults and trigger corresponding alarms or operations. This feature makes the product more responsive and real-time in operation management, helps to detect and solve problems in advance, reduces the probability of accidents, ensures two-way secure interaction between the platform and the pump station automatic control system, ensures the secure transmission and execution of operation instructions, and thus improves the reliability and stability of the entire system. Compared with traditional data transmission methods, this two-way secure interaction mechanism can reduce the risks of misoperation and malicious attacks. The improved PBFT consensus algorithm is used to solve the problem of mutual trust between nodes in a decentralized system, ensuring the consistency and reliability of data. This feature helps to improve the trust level between the pump station management platform and the data acquisition terminal, and while ensuring the accuracy and integrity of the data, it enhances the overall credibility of the product.
