Description

Technical Field

[0001] The present invention belongs to the technical field of issuing commands for intelligent door machines, and in particular, relates to a method and system for issuing commands for intelligent door machines based on blockchain. Background Art

[0002] After the intelligent gantry crane of the hydropower station was put into operation, it brought a lot of convenience and efficiency improvement. Through remote operation, the gates of the power station can be quickly opened and closed, thereby improving the operating efficiency and safety of the hydropower station. However, the operation of this intelligent gantry crane also brings some potential network security risks; first, the convenience of remote operation also brings security challenges. Since the intelligent gantry crane needs to be remotely controlled through the network, this means that there is a risk of being attacked by hackers. Hackers may use network vulnerabilities or weak passwords to invade the intelligent gantry crane system to gain control of the gates; once hackers successfully invade, they may maliciously operate the gates, such as closing the gates to interrupt the operation of the hydropower station, or deliberately opening the gates to cause flooding and other serious consequences; secondly, the remote operation of the intelligent gantry crane also has data security risks; the intelligent gantry crane system needs to collect and process a large amount of operating data, such as the opening and closing status of the gates, water levels and other information. These data may contain sensitive information, such as the operating status of the hydropower station, power supply, etc. If hackers successfully hack into the smart gantry system, they may steal these sensitive data, thus posing a serious threat to the operation and safety of the hydropower station. In addition, the remote operation of the smart gantry may also be threatened by physical security. Since the smart gantry system needs to be connected to other devices and sensors, these devices and sensors may be at risk of being damaged or tampered with. Hackers can interfere with the normal operation of the smart gantry by destroying or tampering with these devices and sensors. They may tamper with the sensor data, causing the smart gantry to misjudge the water level and then perform incorrect operations on the gate. Finally, the remote operation of the smart gantry may also be affected by human factors. Since the smart gantry requires personnel to perform remote control, if the operator's account is stolen or the password is leaked, hackers may impersonate the operator to perform malicious operations. In addition, if the operator lacks security awareness or is negligent, it may also cause operational errors, which will have unpredictable effects on the operation and safety of the hydropower station.

[0003] In summary, the remote operation of the intelligent gantry crane in the hydropower station has brought many conveniences and improved efficiency, but there are also some potential network security risks. These risks include hacker attacks, data security threats, physical security threats and human factors; therefore, it is necessary to design a method and system for issuing instructions to the intelligent gantry crane based on blockchain to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method and system for issuing instructions for intelligent gantry cranes based on blockchain. The method aims to solve the problem in the prior art that the remote operation of intelligent gantry cranes in hydropower stations is easily affected by hacker attacks, data security threats, physical security threats and human factors. The blockchain technology has its own decentralized, transparent and tamper-proof characteristics, which is used to enhance mutual trust and data reliability between devices, thereby ensuring the safe operation of intelligent gantry cranes in hydropower stations and providing reliable protection for the normal operation and safety of hydropower stations.

[0005] In order to achieve the above technical effects, the technical solution adopted by the present invention is: The method for issuing instructions to an intelligent door machine based on blockchain includes the following steps: S1, using the blockchain’s smart contract technology to upload the gantry crane action instruction red line to the blockchain network, and receive the gantry crane action instruction through the work order operation system; S2, the door crane action instructions are recorded in the door crane action database component of the blockchain to form a block, and the door crane action instructions are broadcast to the entire network using the distributed ledger technology of the blockchain, and the data is cross-verified through the consensus mechanism, and the public key, private key and data signature are used to access and jointly maintain the data; S3, generating a credential data hash code for the door machine action instruction through a hash operation, and irreversibly storing the generation time of the hash code and the driver's blockchain account; S4, collects the facial features of the gantry crane driver in real time and compares the facial features with the data of the special equipment operator; S5, using the blockchain’s smart contract algorithm to automatically match and verify the door crane action instructions that have passed the comparison with the door crane action instruction red line, and send the automatic matching verification results to the auditor for manual re-inspection; S6, receiving the audit result of manual re-inspection, and storing the door machine action instructions that have passed the audit in the door machine action database; S7, verify the correctness of the door crane action instructions from time to time according to the information in the door crane action database; S8, executes preset actions in order according to the door crane action instructions in the door crane action database, uses the blockchain encryption algorithm to asymmetrically encrypt the door crane action instructions and door crane action information, and uses the hash algorithm to ensure the integrity of the encrypted data.

[0006] Preferably, in step S1, the door crane action instruction red line is judged by obtaining unit status data through the unit online monitoring system or other systems.

[0007] Preferably, the gate crane action instruction red line includes that the person giving the instruction holds a valid special equipment operator certificate, has passed the training and has the gate operation qualification, the unit corresponding to the gate to be closed has been shut down, and the unit corresponding to the gate to be opened has the conditions for starting up and all personnel have been evacuated.

[0008] Preferably, in step S1, the door machine action instruction includes the instruction issuance time, the instruction source location code, the driver information, the door machine number, the target unit number, the target gate number and the gate action information.

[0009] Furthermore, the gate action information includes open, closed or others.

[0010] Preferably, in step S4, the person-document verification includes using the distributed ledger technology of blockchain to uniquely compare the gate crane action instructions with the driver's ID card data, establish a unique timestamp and signature password, and verify that the driver operating the gate crane holds a valid special equipment operator certificate and has passed the training and is qualified to operate the gate.

[0011] Preferably, in step S6, the gate action status is displayed in real time and the gate database is updated in time.

[0012] Preferably, after each door machine action instruction is executed, the door machine action instruction information in the door machine action database is marked with an executed mark.

[0013] Preferably, the gantry crane action database automatically generates monthly gantry crane action database statistical reports. Each record in the statistical data will be stamped with a timestamp in the process link, clearly recording the time when each action instruction was issued, the instruction source location code, driver information, gantry crane number, target unit number, target gate number and gate action information, and the statistical data ledger will be updated through the consensus mechanism of the blockchain.

[0014] Preferably, in step S8, the Merkle tree is used to perform integrity check on the door machine action statistics to ensure the integrity of the encrypted data.

[0015] Preferably, the blockchain-based intelligent door machine command issuing system includes a memory and a processor, and the memory stores a computer program that can be loaded and executed by the processor, and the computer program is used to execute the blockchain-based intelligent door machine command issuing method.

The entire process is monitored, and all operation records are broadcast to the entire network to ensure the safety, accuracy, and monitorability of the gantry crane action process.

[0017] The beneficial effects of the present invention are as follows: 1. Traditional smart door machine systems are usually controlled by a central server. This centralized structure is easy to become a target of attack. This application uses blockchain technology to achieve decentralized control. Each device can participate in the blockchain network without single point of failure and single attack target.

[0018] 2. The blockchain technology used in this application can provide data encryption and privacy protection functions to ensure that instructions and data are not tampered with or stolen during transmission and storage. Only authorized devices can decrypt and access data to protect user privacy and security.

The intelligent door machine instruction issuing system can record instructions on the blockchain to ensure the authenticity and integrity of the instructions. This can prevent malicious attackers from tampering with or forging instructions and improve the security of the system.

[0020] 3. The smart contract in the blockchain of this application can automatically execute instructions and ensure the security and reliability of execution. Smart contracts can define the execution conditions and restrictions of instructions. Only instructions that meet the conditions will be executed, avoiding human errors and malicious operations.

[0021] 4. The transactions and data records in the blockchain of this application are public and can be viewed and verified by all participants. This transparency can help detect and prevent abnormal operations and attacks, and improve the security of the system. At the same time, the traceability of the blockchain can help track and trace the source and execution process of instructions, making it easier to discover and solve problems; applying blockchain technology to the intelligent door machine instruction issuance system can provide a safer and more reliable communication and instruction execution environment, significantly reducing network security risks.
