[0002] In modern power systems, remote control of smart circuit breakers is crucial to improving the safety and reliability of power grids. With the development of smart grids and the application of Internet of Things technology, smart circuit breakers not only need to have remote control functions, but also need to ensure the security, reliability and real-time nature of communications. Traditional circuit breaker control systems usually rely on wired communications or simple wireless communications, which not only limits the flexibility and response speed of the system, but also poses security risks, such as frequency band interference, communication interruptions and unauthorized access. In addition, the logging and maintenance strategies in traditional methods are often based on centralized management, which is susceptible to single point failures and lacks effective analysis and utilization of historical data, making it difficult to achieve predictive maintenance.

[0003] The existing intelligent circuit breaker control system shows significant limitations when facing the complex power network environment. First, in terms of communication, the current system mostly uses fixed frequency bands for wireless communication and cannot dynamically select the optimal working frequency band according to environmental changes, resulting in unstable communication quality, especially in the presence of interference from multiple wireless devices. Communication efficiency and reliability are greatly reduced. Secondly, the security mechanism of the existing system is relatively weak, mainly relying on simple identity authentication and encryption methods, and it is difficult to resist complex network attacks and unauthorized access. In particular, when users issue operation requests through mobile terminals, there is a lack of multi-level identity authentication and encryption processing, which increases security risks.

[0044] In a second aspect, an embodiment of the present invention provides a circuit breaker control system based on wireless communication, comprising:

[0045] A connection module is used to connect multiple smart circuit breakers to a central control system using a secure authenticated wireless network with adaptive spectrum sensing capabilities, obtaining a network environment that dynamically selects the best operating frequency band and only authenticates device communications through a public key infrastructure;

[0049] A generation module is used to store the log entries using blockchain technology, perform predictive maintenance processing on historical log data based on a time series analysis algorithm, and coordinate the operational consistency between multiple central control systems through a consensus algorithm under a distributed decision-making framework to generate tamper-proof and distributed maintenance and control records. In a third aspect, an embodiment of the present invention provides a computing device, including a processor and a memory, wherein a computer program is stored in the memory, and the processor is configured to run the computer program to execute a circuit breaker control method based on wireless communication as described in any one of the first aspects.

[0050] In a fourth aspect, an embodiment of the present invention provides a computer storage medium having computer program instructions stored thereon, wherein the computer program instructions, when executed by a processor, implement a circuit breaker control method based on wireless communication as described in any one of the first aspects.

[0051] In an embodiment of the present invention, a secure authenticated wireless network with adaptive spectrum sensing capability is used to connect multiple intelligent circuit breakers to a central control system, so as to obtain a network environment that dynamically selects the best working frequency band and only verifies device communication through a public key infrastructure; according to an operation request issued by a user through a mobile terminal, a zero-knowledge proof algorithm is used in the network environment to verify the identity of the user, and the control command is encrypted based on the advanced encryption standard to generate an encrypted control command that is sent to the intelligent circuit breaker in a preset area in real time; based on a hash chain security protocol and a digital signature technology, the legality and integrity of the encrypted control command of the intelligent circuit breaker and the authenticity of the source of the instruction are verified to obtain an operation instruction after verification; a corresponding preset action is executed on the operation instruction after verification to obtain execution status information, and the execution status information is fed back to the central control system according to the advanced encryption standard feedback mechanism to generate a log entry; the log entry is stored using blockchain technology, and predictive maintenance processing is performed on historical log data based on a time series analysis algorithm, and the operation consistency between multiple central control systems is coordinated through a consensus algorithm under a distributed decision-making framework to generate an unalterable and distributed maintenance and control record. The technical solution provided by the present invention enhances the communication flexibility and reliability, strengthens the security, reduces the risk of unauthorized access, ensures the accuracy and reliability of operation instructions, supports faster and more accurate operation decisions, and provides a strong guarantee for the long-term stable operation of the system.

[0052] Furthermore, by introducing the chaotic mapping algorithm to perform nonlinear transformation processing on the data sequence in the timestamp and random number enhanced encryption command, as well as subsequent displacement coding and hash processing, the complexity and randomness of the encryption command are greatly increased, making the cracking difficulty significantly increased, thereby improving the security and confidentiality of command transmission;

[0053] The characteristics of the chaotic system are used to dynamically disrupt the hashed data sequence to ensure that each generated encryption command is unique. Even the same original command will produce different encryption results due to different time and random numbers, further enhancing the system's anti-attack capability.

[0054] Despite multiple complex transformations and scrambling processes, the encrypted command generated after scrambling can still be correctly parsed and executed. This is because all processing steps strictly follow the established rules, ensuring the integrity and recoverability of the data and maintaining the validity of the command.

[0055] The data sequence after displacement encoding is summarized by a hash function to generate a hash value with a fixed length. This process not only adds an extra layer of security, but also provides an efficient means of verifying the integrity of the data. Any tampering attempt will cause the hash value to change, which can be easily detected.

[0056] From nonlinear transformation to dynamic disturbance processing, the entire encryption process has been carefully designed to ensure that the result of each step is directly used as the input of the next step, forming a coherent and efficient encryption process, reducing redundant operations, and improving overall encryption efficiency; these aspects or other aspects of the present invention will be more concise and easy to understand in the description of the following embodiments.

[0061] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0064] Figure 1 A flow chart of a circuit breaker control method based on wireless communication is provided for an embodiment of the present invention, such as Figure 1 As shown, the method includes:

[0065] Step 101: Connect multiple smart circuit breakers to a central control system using a secure authenticated wireless network with adaptive spectrum sensing capabilities, and obtain a network environment that dynamically selects the best operating frequency band and only authenticates device communications through a public key infrastructure;

[0066] In this step, a secure authenticated wireless network with adaptive spectrum sensing capability is used to connect multiple intelligent circuit breakers to the central control unit. Adaptive spectrum sensing technology allows the network to monitor the surrounding electromagnetic environment in real time and dynamically select the best working frequency band to avoid interference. The secure authenticated wireless network ensures that the communicating devices must be authenticated before they can participate in the communication. The authentication is performed using the public key infrastructure (PKI), which is a security framework for creating, managing, distributing, using, storing and revoking digital certificates to ensure that only authorized devices can access.

[0067] First, the wireless network uses spectrum analysis tools to detect the signal-to-noise ratio and interference of the current frequency band, and selects the frequency band with the highest signal-to-noise ratio and the lowest interference as the working frequency band. Then, all devices attempting to access the network must provide a digital certificate issued by a trusted certification authority. The authentication server in the network verifies the validity and integrity of the certificate, confirms the legality of the device, and allows it to join the network and participate in communication.

[0068] Assume that, in a smart grid environment, the communication between multiple smart circuit breakers and a central control unit relies on a secure authenticated wireless network with adaptive spectrum sensing capabilities. When a new device attempts to join the network, it first sends a request containing a digital certificate. The authentication server in the network verifies the certificate and ensures that the device's identity is legitimate before allowing the device to access and participate in communication. For example, when a new smart circuit breaker is installed in a power facility, it needs to send a certificate request to the network. Only after the network confirms its legitimacy can the circuit breaker work normally and communicate with the central control unit.

[0069] Step 102: according to the operation request sent by the user through the mobile terminal, the user identity is verified using a zero-knowledge proof algorithm in the network environment, and the control command is encrypted based on the advanced encryption standard to generate an encrypted control command that is sent to the smart circuit breaker in the preset area in real time;

[0070] In this step, it is described that when a user issues an operation request through a mobile terminal, the user identity is verified using a zero-knowledge proof algorithm in the network environment, and the control command is encrypted based on the Advanced Encryption Standard (AES). The zero-knowledge proof algorithm allows the user to prove his or her identity without revealing any additional information. AES is a symmetric encryption algorithm;

[0071] Used to protect the security of data transmission and ensure that commands will not be eavesdropped or tampered with during transmission. When a user initiates an operation request, the mobile terminal uses a zero-knowledge proof algorithm to generate a certificate that can prove to the central control unit that the user has the correct identity information without leaking any additional information. The central control unit confirms the user's identity by checking the validity of this certificate. Once the verification is successful, the central control unit uses the AES-GCM mode to encrypt the control command to be sent to the smart circuit breaker in the preset area to ensure the confidentiality and integrity of the command;

[0072] Continuing with the implementation example of the previous step, the user initiates a circuit breaker operation request through a smartphone application. The application first uses a zero-knowledge proof algorithm to interact with the central control unit to complete user identity authentication. After the verification is passed, the application uses the AES-GCM mode to encrypt the control command to ensure that the command will not be eavesdropped or tampered with during transmission. The encrypted command is then sent to the smart circuit breaker in the specified area. For example, the user can remotely turn off or turn on the power supply to a specific area without worrying about the command being intercepted by a third party.

[0073] Step 103: Based on the hash chain security protocol and digital signature technology, the legality and integrity of the encrypted control command of the intelligent circuit breaker and the authenticity of the source of the command are verified to obtain the verified operation command;

[0074] In this step, based on the hash chain security protocol and digital signature technology, the legitimacy and integrity of the received encrypted control command are verified, as well as the authenticity of the source of the command. The hash chain security protocol builds a secure data chain by linking multiple hash values ​​to ensure data integrity and non-tamperability. The digital signature technology generates an electronic signature through a private key to confirm the authenticity of the source of the message. The recipient can confirm the authenticity and integrity of the command by verifying the signature.

[0075] After receiving the encrypted control command, the smart circuit breaker first recalculates the hash value according to the hash value attached to the command and compares it with the original hash value to confirm that the command has not been tampered with. Then, it uses the corresponding public key to verify the digital signature attached to the command to ensure that the command is indeed from the expected sender. After the verification is passed, the command is considered to be legal and authentic, and the corresponding operation can be performed;

[0076] Continuing with the previous embodiment, after receiving an encrypted control command, the intelligent circuit breaker first verifies the integrity and legitimacy of the command through the hash chain security protocol to ensure that the command has not been tampered with. Subsequently, the authenticity of the command source is verified through digital signature technology to ensure that the command is indeed issued by the central control unit. Only when both verifications are passed will the intelligent circuit breaker perform the corresponding action, such as cutting off or restoring the circuit, which ensures that the circuit breaker will not execute illegal commands even if there is a potential threat to the network.

[0077] Step 104: executing a corresponding preset action on the verified operation instruction to obtain execution status information, and feeding back the execution status information to the central control system according to the Advanced Encryption Standard feedback mechanism to generate a log entry;

[0078] In this step, it is described that the corresponding preset action is executed for the operation instruction after verification, the execution status information is obtained, and the execution status information is fed back to the central control unit according to the advanced encryption standard feedback mechanism to generate a log entry. The preset action means that the intelligent circuit breaker performs a specific action according to the received operation instruction, such as cutting off or restoring the circuit. The execution status information records the result after the intelligent circuit breaker executes the operation, including whether the specified action is successfully completed. The advanced encryption standard feedback mechanism ensures that the information fed back to the central control unit is also encrypted to maintain the security of communication;

[0079] Once the operation instruction is verified, the intelligent circuit breaker will perform the corresponding preset action, such as cutting off or restoring the circuit, and record the execution status information. Subsequently, this information will be encrypted and fed back to the central control unit to generate a log entry for subsequent query and analysis. The feedback mechanism ensures that all communications remain secure and prevents the status information from being tampered with or stolen;

[0080] The smart circuit breaker executes the command received from the central control unit, such as disconnecting the circuit. After completion, it records the execution status information and feeds this information back to the central control unit using the AES encryption mechanism. The central control unit decrypts the received status information, confirms that the circuit breaker has correctly executed the command, and records this event as a log entry. For example, if a user issues a command to turn off the power supply to a certain area through a mobile application, the smart circuit breaker will immediately feed back the execution status to the central control unit after executing the command, ensuring that the user can understand the execution status of the command in a timely manner.

[0081] Step 105: Using blockchain technology to store the log entries, performing predictive maintenance processing on historical log data based on a time series analysis algorithm, and coordinating the operational consistency among multiple central control systems through a consensus algorithm under a distributed decision-making framework to generate an unalterable and distributed maintenance and control record;

[0082] In this step, blockchain technology is used to store log entries, and predictive maintenance processing is performed on historical log data based on time series analysis algorithms. The consensus algorithm is used to coordinate the consistency of operations among multiple control units under a distributed decision-making framework to generate non-tamperable and distributed maintenance and control records. Blockchain technology provides a decentralized distributed ledger to ensure the non-tamperability and distribution of data. Time series analysis algorithms help extract trends and patterns from historical data to support predictive maintenance. Consensus algorithms ensure operational consistency between different nodes and maintain the reliability of distributed systems.

[0083] Log entries are stored through blockchain technology to ensure the immutability and distribution of data. At the same time, historical log data is analyzed based on time series analysis algorithms to identify potential failure modes and trends in advance and support predictive maintenance. In addition, under the distributed decision-making framework, the consensus algorithm is used to coordinate the consistency of operations among multiple control units to generate tamper-proof and distributed maintenance and control records to ensure long-term stable operation.

[0084] Continuing with the previous embodiment, after the central control unit receives the execution status information fed back by the smart circuit breaker, it stores it as a log entry on the blockchain. The blockchain ensures the immutability and distribution of the log, so that all relevant parties can trust these records. At the same time, the central control unit uses a time series analysis algorithm to analyze the accumulated log data, identify possible failure modes, and arrange maintenance work in advance. For example, if certain types of commands frequently lead to abnormal conditions, the system can automatically trigger preventive maintenance recommendations. In addition, multiple central control units coordinate operations through a consensus algorithm to ensure the operational consistency and reliability of all control units, thereby improving the stability of the entire power network.

[0085] Since the security mechanism of the existing system is relatively weak and mainly relies on simple identity authentication and encryption means, it is difficult to resist complex network attacks and unauthorized access. In particular, when the user issues an operation request through a mobile terminal, there is a lack of multi-level identity authentication and encryption processing, which increases the security risk. Based on this, the present invention provides an embodiment. According to the step 102, according to the operation request issued by the user through the mobile terminal, the user identity is verified in the network environment using a zero-knowledge proof algorithm, and the control command is encrypted based on the advanced encryption standard to generate an encrypted control command that is sent to the intelligent circuit breaker in the preset area in real time. Specifically, the following steps are included:

[0086] Step 201: using a zero-knowledge proof algorithm combined with biometrics technology, double identity authentication is performed on an operation request sent by a user through a mobile terminal to obtain a successfully authenticated user operation request;

[0087] In this step, the zero-knowledge proof algorithm is combined with biometrics to perform double authentication on the operation request issued by the user through the mobile terminal. Zero-knowledge proof is an encryption method that allows one party (the prover) to prove to another party (the verifier) ​​that he or she has certain information without revealing the information itself. Biometrics include fingerprint, facial or iris recognition, etc., which are used to enhance the security and accuracy of identity authentication;

[0088] When a user initiates an operation request, the user first completes the initial identity verification through the biometric interface provided by the mobile terminal, and then uses the zero-knowledge proof algorithm to interact with the central control unit to complete the second identity verification. This ensures that only users who have undergone dual verification can initiate valid operation requests;

[0089] In a smart grid environment, a user wants to remotely control a circuit breaker through a smartphone application. The user first enters a fingerprint on the phone to complete the initial identity authentication. Then, the application uses a zero-knowledge proof algorithm to interact with the central control unit to complete the second identity authentication. Only when both verifications are successful will the user's operation request be accepted and processed.

[0090] Step 202: Based on context-aware technology, the geographical location, time pattern and historical behavior data of the successfully verified user operation request are analyzed, the command priority is adjusted, and a control command with a priority mark is generated;

[0091] In this step, the geographical location, time pattern and historical behavior data of the successfully verified user operation request are analyzed, the command priority is adjusted, and a control command with a priority tag is generated. The context-aware technology can dynamically adjust the system's response strategy according to the user's current environment and habits, thereby improving user experience and security;

[0092] Once the user's identity is authenticated, the central control unit analyzes the user's geographic location, current time, and historical behavior data to assess the rationality and urgency of the request. Based on these factors, the system automatically adjusts the priority of the command and adds a corresponding priority tag to each command.

[0093] Continuing with the embodiment of the previous step, after the central control unit receives the user's operation request, it will check whether the user's current location is within its authorized range, while considering the current time and the user's historical behavior pattern. For example, if the user often turns off the power of a specific area at 7 pm on weekdays, the request at this time will be given a higher priority. On the contrary, if the request occurs in an abnormal time period or comes from an unknown location, it will be marked as low priority or further reviewed.

[0094] Step 203: Using a combination of advanced encryption standard and quantum encryption technology, perform multi-level encryption processing on the control command with the priority mark to generate a multi-encrypted control command;

[0095] In this step, the Advanced Encryption Standard (AES) and quantum encryption technology are combined to perform multi-level encryption processing on the control commands with priority tags to generate multiple encrypted control commands. AES is a symmetric encryption algorithm used to protect the security of data transmission; quantum encryption technology provides a higher level of security guarantee to prevent potential threats brought by quantum computing;

[0096] The central control unit first uses the AES algorithm to perform primary encryption on the control commands with priority marks to generate the initially encrypted control commands. Next, the initially encrypted commands are re-encrypted using quantum encryption technology to add an extra layer of security to ensure that the commands will not be eavesdropped or tampered with during transmission.

[0097] After receiving the user's control command with a priority mark, the central control unit first encrypts the command using AES-256 to ensure its confidentiality and integrity. Then, to further enhance security, the system uses quantum key distribution (QKD) technology to re-encrypt the encrypted command. In this way, even if quantum computers appear in the future, it will be difficult to crack the command content, ensuring the highest level of security.

[0098] Step 204: confirming that the smart circuit breakers in the preset area are in the authorized area according to the geo-fencing technology, and sending the multi-encrypted control commands to the smart circuit breakers in the preset area in real time;

[0099] In this step, the smart circuit breakers in the preset area are confirmed to be in the authorized area according to the geo-fencing technology, and the multi-encrypted control commands are sent to the smart circuit breakers in the preset area in real time. The geo-fencing technology sets a virtual boundary to ensure that only devices within the specified range can receive and execute commands, thereby enhancing the safety and controllability of the operation.

[0100] Before sending the multi-encrypted control command, the central control unit will first confirm whether the location of the target smart circuit breaker is within the authorized area through geo-fencing technology. Only when it is confirmed, the control command will be sent to the corresponding smart circuit breaker to ensure that the command is effective only within the expected range;

[0101] Continuing with the previous embodiment, before the central control unit is ready to send the multi-encrypted control command, it will first check whether the target smart circuit breaker is located within the pre-set geographic fence. For example, the user wants to turn off a circuit in the home, but the control command will only be sent to the corresponding smart circuit breaker when the smart home system confirms that the user is indeed at home or nearby. This mechanism ensures that even if the user account is hacked, it is impossible to remotely control devices that are not in the authorized area, thereby improving overall security.

[0102] Furthermore, the present invention also provides an embodiment, according to the step 203, the control command with the priority mark is subjected to multi-level encryption processing by combining the advanced encryption standard with the quantum encryption technology to generate a multi-encrypted control command, which specifically includes the following steps:

[0103] Step 301: using the Advanced Encryption Standard algorithm, performing initial encryption processing on the control command with the priority mark to generate a preliminary encrypted control command;

[0104] In this step, the Advanced Encryption Standard (AES) algorithm is used to perform initial encryption processing on the control command with the priority mark to generate a preliminary encrypted control command. AES is a widely used symmetric encryption algorithm that provides a variety of key length options (such as 128 bits, 192 bits, and 256 bits) to ensure the security and confidentiality of data transmission. The priority mark is information attached to the control command, indicating the importance and execution order of the command;

[0105] When the control command with the priority mark is ready, the central control unit uses the AES algorithm to encrypt it for the first time, which includes selecting an appropriate key length (such as 256 bits) and applying an appropriate encryption mode (such as GCM mode) to ensure data integrity and confidentiality. The command after the initial encryption is called a preliminary encrypted control command and is ready to enter the next step of enhanced processing;

[0106] In a smart grid environment, users send control commands with priority tags through mobile terminals, such as emergency power shutdown of a certain area. After receiving the command, the central control unit uses the AES-256-GCM mode to perform initial encryption on the command to ensure that it will not be eavesdropped or tampered with during transmission. At this point, the command already contains the user's operating intention and its priority information, but it still needs to be further enhanced to increase security.

[0107] Step 302: Based on the dynamic timestamp and the random number sequence, the preliminary encryption control command is enhanced to obtain a timestamp and random number enhanced encryption command;

[0108] In this step, the preliminary encrypted control command is enhanced based on a dynamic timestamp and a random number sequence to obtain a timestamp and random number enhanced encrypted command. The dynamic timestamp is a time identifier generated in real time with each operation, and the random number sequence is a string of unpredictable values. The combination of the two can significantly improve the uniqueness and unpredictability of the command and prevent replay attacks and other forms of malicious operations.

[0109] Before sending the initial encrypted control command, a dynamically generated timestamp and a string of random numbers will be embedded, which not only increases the uniqueness of the command, but also makes each command generated different even if the content is the same, enhancing the anti-tampering capability. After embedding these elements, the command becomes a timestamp and random number enhanced encryption command, providing a more secure foundation for subsequent processing;

[0110] Continuing with the implementation example of the previous step, the control command that has been initially encrypted will then be embedded with a dynamic timestamp generated by the current time and a string of random numbers. For example, if a user issues a command to turn off the power, the system will add the current time (accurate to seconds) as a timestamp in the command and append a string of random numbers. This ensures that even if the same user issues the same command again, each command will be unique due to the difference in timestamp and random number, thereby effectively preventing replay attacks.

[0111] Step 303: using a chaotic mapping algorithm to scramble the timestamp and random number enhanced encryption command to generate a scrambled encryption command;

[0112] In this step, the timestamp and random number enhanced encryption command are disturbed by using a chaotic mapping algorithm to generate a disturbed encryption command. Chaotic mapping is a nonlinear transformation method with initial condition sensitivity and unpredictability of long-term behavior. It can be used to convert input data into a result that looks random and is difficult to reverse engineer, greatly improving the security and complexity of the data.

[0113] The timestamp and random number enhanced encryption commands are transformed nonlinearly through the chaotic mapping algorithm to disrupt the structure and order of the original data. This disruption process not only increases the complexity of the command, but also makes each generated encryption command unique. Even if the same data is input, the output results will be completely different due to slight differences in the initial conditions. The final generated command is called the disrupted encryption command, ready to receive the final step of encryption enhancement;

[0114] Continuing with the previous embodiment, the timestamp and random number enhanced encryption commands are scrambled through a chaotic mapping algorithm. For example, for commands containing specific timestamps and random numbers, the system will transform them according to a preset chaotic mapping function to generate a scrambled encryption command that appears random and cannot be easily restored. Even if an attacker obtains part of the command information, it is difficult to infer the content of the original command, further improving security.

[0115] Step 304: Based on quantum encryption technology, the scrambled encrypted command is re-encrypted to generate a multi-encrypted control command;

[0116] In this step, the scrambled encryption command is encrypted again based on quantum encryption technology to generate multiple encrypted control commands. Quantum encryption technology uses the principles of quantum mechanics to provide a theoretically unbreakable encryption method, especially quantum key distribution (QKD) technology, which can securely share keys between communicating parties to ensure that even if powerful quantum computers appear in the future, the encrypted information cannot be cracked.

[0117] The scrambled encrypted command will be re-encrypted by quantum encryption technology before being sent. This process usually involves using the quantum key distribution (QKD) protocol to generate and distribute one-time encryption keys, and then using these keys to encrypt the command. In this way, even if the command is intercepted while being transmitted on the network, a third party without the corresponding key cannot decrypt or tamper with the command content, ensuring the highest level of security;

[0118] Continuing with the previous embodiment, the scrambled encrypted command is re-encrypted through quantum encryption technology. For example, in a smart grid environment, a secure key sharing channel is established in advance between the central control unit and the target smart circuit breaker through the quantum key distribution protocol. When a command needs to be sent, the central control unit uses this pre-shared quantum key to re-encrypt the scrambled encrypted command to generate a multi-encrypted control command. Even if a quantum computer appears in the future, it is difficult to crack the command content, ensuring that the communication from the central control unit to the smart circuit breaker is absolutely secure.

[0119] Through the above four steps, the entire encryption process not only ensures a high degree of security and reliability, but also greatly enhances the security of command transmission through multi-layer encryption and complex processing mechanisms, forming a complete encryption chain, ensuring that every link from command generation to execution is fully protected, and ensuring the robust operation of the intelligent circuit breaker control system in the face of potential threats. Based on this, the present invention provides an embodiment, according to the step 303, using a chaotic mapping algorithm, the timestamp and random number enhanced encryption command is disturbed to generate a disturbed encryption command, specifically comprising the following steps:

[0120] Step 401: using a chaotic mapping algorithm, performing nonlinear transformation processing on the data sequence in the timestamp and random number enhanced encryption command to obtain a transformed data sequence;

[0121] In this step, a chaotic mapping algorithm is used to perform nonlinear transformation on the data sequence in the timestamp and random number enhanced encryption command to obtain a transformed data sequence. Chaotic mapping is a nonlinear dynamic system based on a mathematical model. Its output is highly sensitive and unpredictable. It is suitable for generating complex and difficult to reverse engineer data sequences. This transformation increases the complexity of the data, making each generated data sequence unique.

[0122] The data sequence of the timestamp and random number enhanced encryption command is input into the chaotic mapping algorithm, which disrupts the structure and order of the original data through a series of nonlinear transformation operations. This not only increases the complexity of the data, but also ensures that each generated data sequence is completely different due to slight differences in the initial conditions, thereby enhancing the security and anti-attack capabilities of the data.

[0123] Assume that, in a smart grid environment, control commands enhanced with timestamps and random numbers are first transformed nonlinearly through a chaotic mapping algorithm. For example, commands containing specific timestamps and random numbers are transformed according to a preset chaotic mapping function to generate a transformed data sequence that appears random and cannot be easily restored. Even if an attacker obtains part of the information, it is difficult to infer the content of the original command, further improving security.

[0124] Step 402: Based on the adaptive shift coding technology, the transformed data sequence is subjected to bit position adjustment processing to generate a shift-coded data sequence;

[0125] In this step, based on the adaptive displacement coding technology, the transformed data sequence is subjected to bit position adjustment processing to generate a displacement-coded data sequence. Adaptive displacement coding is a data coding method that can dynamically adjust the position of bits according to data characteristics to increase the complexity and uniqueness of the data, prevent the emergence of fixed patterns, and make each command more difficult to predict and crack.

[0126] The transformed data sequence is processed by adaptive displacement coding technology, which adjusts the position of bits according to certain rules to ensure the randomness and uniqueness of the data sequence. Even the same input will produce different outputs due to different coding rules. The resulting displacement-coded data sequence further enhances the security of the command.

[0127] Continuing with the implementation example of the previous step, the data sequence transformed by the chaotic mapping algorithm is then processed using adaptive displacement coding technology. For example, the system dynamically adjusts the position of each bit according to predefined rules, making the transformed data sequence more complex and random, ensuring that even the same command will have different encoding results in different situations, greatly improving the security and anti-tampering capabilities of the command.

[0128] Step 403: using a hash function to perform summary processing on the displacement-encoded data sequence, generating a hash value with a fixed length, and obtaining a hash-processed data sequence;

[0129] In this step, the displacement-encoded data sequence is digested by using a hash function to generate a hash value of a fixed length to obtain a hash-processed data sequence. The hash function maps data of any length to a string of fixed length (hash value) and ensures that a small change in the input data will result in a huge change in the hash value. This feature is used to verify the integrity and authenticity of the data. The displacement-encoded data sequence is digested by using a hash function to generate a hash value of a fixed length. This hash value is not only a compressed representation of the original data, but also provides a means of data integrity verification. Any tampering with the original data will result in a change in the hash value. Therefore, the hash-processed data sequence can be used to confirm that the data has not been modified.

[0130] Continuing with the previous embodiment, the data sequence after adaptive displacement coding is then digested through a hash function. For example, the displacement-coded data sequence is processed using a SHA-256 hash function to generate a 256-bit hash value. This hash value is then used as part of the hashed data sequence for subsequent processing steps and can be used at the receiving end to verify the integrity and authenticity of the data.

[0131] Step 404: According to the characteristics of the chaotic system, dynamically disturb the data sequence after the hashing process to obtain a dynamically disturbed data sequence;

[0132] In this step, according to the characteristics of the chaotic system, the data sequence after the hashing process is dynamically disturbed to obtain the data sequence after dynamic disturbance. The initial condition sensitivity and long-term behavior unpredictability of the chaotic system make it very suitable for generating complex and unique data sequences. The dynamic disturbance process further increases the complexity and randomness of the data, making each generated data sequence unique;

[0133] The hashed data sequence is dynamically disturbed through the characteristics of the chaotic system, including nonlinear transformation of the data sequence according to the preset chaotic parameters, ensuring that each generated data sequence is completely different due to slight differences in the initial conditions. The dynamically disturbed data sequence finally generated has higher security and anti-attack capabilities.

[0134] Continuing with the previous embodiment, the data sequence after hash processing is then dynamically disturbed by the characteristics of the chaotic system. For example, the hash value is nonlinearly transformed according to the preset chaotic parameters to generate a dynamically disturbed data sequence that appears to be random and cannot be easily restored, ensuring that even the same hash value will have different disturbance results under different circumstances, further improving the security and anti-tampering capability of the command;

[0135] Since the operation of the circuit breaker is directly related to the safe and stable operation of the power grid, it is crucial to encrypt the circuit breaker control command in order to prevent illegal operation or malicious attack. The existing encryption method usually adopts static key or simple hash function, which makes the encrypted data vulnerable to cracking. Therefore, the present invention proposes a method for enhancing the encryption strength by using the characteristics of composite chaotic mapping, and improves the security of the circuit breaker control command by introducing an unpredictable dynamic disturbance mechanism. In order to realize dynamic disturbance processing based on the characteristics of chaotic system and ensure high security and unpredictability, the present invention adopts the following optimization steps and calculation formula:

[0136] First, the chaotic mapping parameters are initialized. α1 and α2 represent two different chaotic mapping control parameters, which are inherited from the chaotic mapping algorithm mentioned in the content. x0 and y0 represent the initial conditions, which can be selected from any bit value in the timestamp or random number enhanced encryption command.

[0137] Next, the Henon map is introduced to iteratively optimize the chaotic map parameters. Its iterative formula is as follows:

[0138]

[0139] Where n is the number of iterations. By choosing appropriate α1 and α2, as well as initial conditions x0 and y0, a series of composite chaotic values ​​{(x1, y1), (x2, y2), …, (x N ,y N )}, where N is the length of the data sequence after hashing;

[0140] Then, let the data sequence after hash processing be H = {h1,h2,…,h N}, each h i A byte of the hash value, using a composite chaotic sequence to disrupt the position or value of these bytes, for example, through bit operations, permutation operations and nonlinear transformations; for each hash value byte h i , apply the following multi-layer bit operation formula:

[0141]

[0142] in, Indicates bitwise XOR operation, floor(256×x i ) and (floor(256×y i )) Set the chaos value x i and i Mapped to integers in the range [0,255] to ensure matching with the byte range; to further increase the complexity, the hash value bytes can be piecewise nonlinearly transformed to define a nonlinear function f(x), which depends on the composite chaotic sequence {(x1,y1),(x2,y2),…,(x N ,y N )}, specifically, for each hash value byte h′ i , applying the following nonlinear transformation:

[0143] h″ i =f(h′ i ) = a·sin(b·h′ i +c)+d;

[0144] Among them, a, b, c, d are based on the composite chaotic sequence {(x i ,y i )} Dynamically calculated coefficients, for example:

[0145]

[0146] Finally, to increase the complexity, the positions of the hash value bytes are permuted and a permutation function P is defined, which depends on the composite chaotic sequence {(x1,y1),(x2,y2),…,(x N ,y N)}, specifically, {(x1,y1),(x2,y2),…,(x N ,y N )} after sorting, we get the index sequence {p1,p2,…,p N}, and then rearrange the hash value bytes according to this index sequence:

[0147] H′={h″ p1 ,h″ p2 ,…,h″ pN};

[0148] The final generated H′ is the data sequence after dynamic disturbance processing with multiple layers of disturbance;

[0149] Among them, α1 and α2 represent two different chaotic mapping control parameters, which determine the characteristics of chaotic behavior. In practical applications, suitable values ​​can be selected to ensure good chaotic properties; x0 and y0 represent initial conditions, which are usually selected as time Or any bit value in the random number enhanced encryption command, ensuring that each generated chaotic sequence is unique; N represents the length of the data sequence after hash processing, that is, the number of bytes of the hash value; H represents the data sequence after hash processing, which is composed of hash values ​​of fixed length; h i A byte representing the hash value, representing the i-th element in the hashed data sequence; h′ i Indicates the hash value byte after multiple layers of bit operations; h″ i represents the hash value byte after being disturbed by piecewise nonlinear transformation; P represents the permutation function, which is used to rearrange the position of the hash value byte according to the sorting result of the composite chaotic sequence; H′ represents the data sequence after dynamic disturbance, the final output result.

[0150] In summary, the above optimization method utilizes the unpredictability and sensitivity of the composite chaotic mapping, and also combines multi-layer bit operations, piecewise nonlinear transformation and position permutation to ensure that the data sequence after Hardy processing has undergone sufficient dynamic disturbance processing, thereby significantly enhancing the security and anti-algorithm modification capabilities of the encryption command.

[0151] Step 405: reassembling the dynamically scrambled data sequence into a complete command format to generate a scrambled encryption command;

[0152] In this step, the dynamically scrambled data sequence is reassembled into a complete command format to generate a scrambled encrypted command, ensuring that despite multiple complex transformations and scrambling processes, the final generated command can still be correctly parsed and executed. All processing steps are closely linked to ensure data integrity and consistency;

[0153] The dynamically scrambled data sequence is reassembled according to the pre-defined command format to ensure that the command structure is complete and correct. This includes restoring the necessary metadata (such as command type, priority tag, etc.) and ensuring that the command format meets the requirements of the receiving device. The final generated scrambled encrypted command is not only highly secure, but can also be correctly identified and executed by the smart circuit breaker.

[0154] Continuing with the previous embodiment, the data sequence after dynamic scrambling is finally reassembled into a complete command format. For example, the data sequence after dynamic scrambling is combined with necessary metadata (such as command type, priority tag, etc.) to ensure that the encrypted command structure generated after scrambling is complete and meets the receiving requirements of the smart circuit breaker, ensuring that the command is not only highly secure, but also can be correctly parsed and executed by the target device, thereby completing the entire encryption process and ensuring that the communication from the central control unit to the smart circuit breaker is absolutely secure.

[0155] In terms of communication, currently, fixed frequency bands are mostly used for wireless communication, and the best working frequency band cannot be dynamically selected according to environmental changes, resulting in unstable communication quality. Based on this, the present invention provides an embodiment. According to the step 101, a secure authenticated wireless network with adaptive spectrum sensing capability is used to connect multiple intelligent circuit breakers to a central control system, and a network environment is obtained in which the best working frequency band is dynamically selected and communication with devices is limited to public key infrastructure authentication. Specifically, the following steps are included:

[0156] Step 501: Based on the adaptive spectrum sensing technology, the available frequency bands are monitored and evaluated in real time to obtain the best working frequency band;

[0157] In this step, adaptive spectrum sensing technology allows the wireless network to monitor the surrounding electromagnetic environment in real time, dynamically select the optimal operating frequency band to avoid interference, and evaluate the quality of each available frequency band by detecting parameters such as signal-to-noise ratio and interference level;

[0158] The spectrum sensing module in the wireless network continuously scans the surrounding frequency bands and collects data on signal-to-noise ratio, interference level and other key performance indicators. After analyzing these data, the system will select one or more frequency bands with the highest signal-to-noise ratio and the lowest interference as the candidate best operating frequency bands. The final selected frequency band will be used for subsequent communications.

[0159] Suppose, in a smart grid environment, the communication between multiple smart circuit breakers and the central control unit relies on a secure and authenticated wireless network with adaptive spectrum sensing capabilities. The spectrum sensing module in the network continuously monitors the surrounding electromagnetic environment and evaluates the quality of each frequency band. For example, when it detects that the currently used 2.4GHz band is severely interfered, the system automatically selects a 5GHz band with less interference as the optimal operating frequency band to ensure communication quality and stability.

[0160] Step 502: performing interference detection and avoidance on the optimal working frequency band to generate an optimized optimal working frequency band;

[0161] In this step, interference detection aims to identify external interference sources that may affect the communication quality, while avoidance measures are taken to ensure that the selected frequency band is not significantly interfered by other wireless signals, further improving the reliability of communication;

[0162] Once the preliminary best operating frequency band is determined, the system will continue to monitor the frequency band for new interference sources. If potential interference is detected, the system will take measures (such as switching to an alternate frequency band or adjusting the transmission power) to avoid interference, thereby generating an optimized best operating frequency band. This ensures that communications remain stable even in complex electromagnetic environments.

[0163] Continuing with the implementation example of the previous step, the selected 5GHz frequency band may still encounter sudden interference in actual use. Therefore, the system continues to monitor the frequency band and responds quickly when new interference is detected. For example, if it is found that other devices nearby have also started to use the same 5GHz frequency band, the system will automatically switch to another pre-prepared backup frequency band, or adjust the transmission power to reduce the impact of interference, and finally generate an optimized optimal working frequency band to ensure the continuity and stability of communication.

[0164] Step 503: Utilize the public key infrastructure to authenticate the device accessing the network, and perform secondary verification based on the geographical location information of the device, to obtain a list of devices that have passed the dual verification;

[0165] In this step, the public key infrastructure (PKI) is used to authenticate the device accessing the network, and a secondary verification is performed based on the device's geographic location information to obtain a list of devices that have passed the dual verification. PKI is a security framework for creating, managing, distributing, using, storing, and revoking digital certificates to ensure that only authorized devices can access the network. Geographic location information provides an additional layer of verification and enhances security;

[0166] All devices attempting to access the network must provide a digital certificate issued by a trusted certification authority. The authentication server in the network confirms the legitimacy of the device by verifying the validity and integrity of the certificate. In addition, the system will check the device's geographic location information to ensure that it is located in an authorized area. Only devices that pass this two-factor verification will be added to the device list and allowed to participate in communication;

[0167] Continuing with the previous embodiment, when a new smart circuit breaker attempts to join the network, it first sends a request containing a digital certificate. The authentication server in the network verifies the certificate to ensure that the identity of the device is legitimate. Subsequently, the system checks whether the current location of the device is within its authorized range, for example, confirming that the device is indeed installed in a specific power facility. Only when both verifications are successful will the circuit breaker be added to the list of devices that have passed the dual verification, allowing it to work normally and communicate with the central control unit.

[0168] Step 504: Based on the list of devices that have passed the dual authentication, a network environment is constructed that dynamically selects the best working frequency band after optimization and allows only dual authentication devices to communicate.

[0169] In this step, based on the list of devices that have passed the dual verification, a network environment is constructed that dynamically selects the best working frequency band after optimization and only allows communication by dual-verified devices. This network environment not only selects the best working frequency band to ensure communication quality, but also limits communication to only devices that have passed strict verification, thereby improving overall security.

[0170] The network environment is built based on a list of devices that have passed double verification to ensure that only these devices can communicate on the optimized best working frequency band. The network configuration and security policies will be dynamically adjusted to adapt to the changing frequency band conditions and device status to ensure the security and reliability of communication. This includes setting access control lists (ACLs) and configuring firewall rules to prevent unauthorized devices from accessing.

[0171] Continuing with the previous embodiment, the network environment in the smart grid is dynamically constructed based on a list of devices that have passed dual verification. The central control unit ensures that only those devices that have been authenticated and are located in the authorized area can communicate on the optimized best operating frequency band. For example, when a new smart circuit breaker successfully passes the dual verification, the central control unit updates the network configuration to allow the circuit breaker to communicate with other verified devices on the selected optimized frequency band. At the same time, the security mechanisms in the network (such as ACL and firewall rules) are also adjusted accordingly to ensure that only authorized devices can participate in communication, thereby maintaining the security and reliability of the entire system.

[0172] Based on this, the present invention also provides an embodiment, according to the step 103, based on the hash chain security protocol and digital signature technology, the legality and integrity of the encrypted control command of the intelligent circuit breaker and the authenticity of the instruction source are verified to obtain the verified operation instruction, which specifically includes the following steps:

[0173] Step 601: parsing the verified operation instruction, determining the preset action type and the target intelligent circuit breaker, and obtaining the parsed operation instruction;

[0174] In this step, the verified operation instruction is parsed to determine the preset action type and the target intelligent circuit breaker, and the parsed operation instruction is obtained. The parsing process involves decrypting and interpreting the content of the encrypted command to clarify its intention (such as opening or closing the circuit) and the identity information of the target device;

[0175] Once the operation instruction passes the authentication and integrity check, the intelligent circuit breaker will parse the received command, which includes decrypting the command, extracting key parameters in the command (such as action type, target device identification, etc.), and converting this information into specific control logic. The final generated parsed operation instruction specifies the specific action to be performed and its target device;

[0176] In a smart grid environment, the central control system sends a verified operation instruction to a smart circuit breaker. After receiving the instruction, the circuit breaker first decrypts the command using a pre-shared key, and then parses out the action type (such as turning off the power) and the target device identifier (such as the circuit breaker ID in a specific area) contained in the command. After the parsing is completed, the system is ready to perform the corresponding action based on this information and continue to process the subsequent steps.

[0177] Step 602: Based on the parsed operation instruction, execute a corresponding preset action on the target intelligent circuit breaker, and generate execution status information;

[0178] In this step, based on the parsed operation instruction, the corresponding preset action is performed on the target intelligent circuit breaker, and execution status information is generated. The preset action refers to a specific operation performed according to the parsing result, such as cutting off or restoring the circuit. The execution status information records the result of the operation, including whether the specified action is successfully completed and its specific parameters;

[0179] The intelligent circuit breaker executes the corresponding preset action according to the parsed operation instruction, such as cutting off or restoring the circuit. During the execution process, the system will monitor the status of the operation, record the timestamp of the operation, whether it is successfully completed, any errors encountered, and finally generate execution status information, which will be used for subsequent feedback and log recording;

[0180] Continuing with the implementation example of the previous step, the intelligent circuit breaker executes the action of shutting down the power supply of a specific area according to the parsed operation instruction. It records the time of the operation, whether it is completed successfully, and any related parameters (such as current level). For example, if the operation is completed successfully, the system will generate an execution status information including "successfully shutting down the power supply of area A" and a specific timestamp, which provides accurate operation result feedback for subsequent steps.

[0181] Step 603: Encrypt the execution status information using the Advanced Encryption Standard feedback mechanism to generate an encrypted execution status report;

[0182] In this step, the execution status information is encrypted using the Advanced Encryption Standard (AES) feedback mechanism to generate an encrypted execution status report. AES is a symmetric encryption algorithm that provides a variety of key length options (such as 128 bits, 192 bits, and 256 bits) to ensure the security and confidentiality of data transmission. The feedback mechanism ensures that all communications remain secure and prevents the status information from being tampered with or stolen.

[0183] Before being fed back to the central control system, the execution status information is encrypted using the AES algorithm, which includes selecting an appropriate key length (e.g., 256 bits) and applying an appropriate encryption mode (e.g., GCM mode) to ensure data integrity and confidentiality. The encrypted information is called the encrypted execution status report, which is ready to be sent back to the central control system.

[0184] Continuing with the previous embodiment, after the smart circuit breaker generates the execution status information including the operation result, it is encrypted using the AES-256-GCM mode to ensure that it will not be eavesdropped or tampered with during transmission. For example, for the status information of "successfully turning off the power of area A", an encrypted execution status report is generated, and only the central control system can decrypt and read this information, thereby ensuring the security and reliability of the feedback mechanism.

[0185] Step 604: sending the encrypted execution status report to the central control system in real time, and decrypting it by the central control system to obtain decrypted execution status information;

[0186] In this step, the encrypted execution status report is sent to the central control system in real time, and is decrypted by the central control system to obtain the decrypted execution status information. The real-time transmission ensures that the central control system can obtain the latest operation results in a timely manner, and the decryption process restores the original execution status information for further processing;

[0187] The encrypted execution status report is sent to the central control system in real time through a secure communication channel. After receiving the report, the central control system uses the pre-shared key to decrypt it and restore the original execution status information, ensuring the security of all communications while allowing the central control system to understand the actual results of each operation in a timely manner;

[0188] Continuing with the previous embodiment, the smart circuit breaker sends the encrypted execution status report to the central control system in real time via the wireless network. After receiving the report, the central control system uses the key pre-shared with the smart circuit breaker to decrypt the report content and restore the original execution status information, such as "successfully shut down the power supply of area A", which enables the central control system to immediately confirm that the operation has been completed as expected and prepare for the next step of processing.

[0189] Step 605: Generate a log entry including operation time, content and result in the central control system according to the decrypted execution status information;

[0190] In this step, the log entries record the specific circumstances of each operation in detail, including the time of occurrence, the content of execution and its results, which provides an important basis for subsequent analysis and maintenance;

[0191] The central control system generates detailed log entries based on the decrypted execution status information, including the timestamp of the operation, the specific content of the execution (such as which area is powered off), the result of the operation (such as success or failure), and other relevant parameters. The generated log entries are not only used to confirm the current operation, but also support long-term historical data analysis and predictive maintenance;

[0192] Continuing with the previous embodiment, the central control system generates a detailed log entry based on the decrypted execution status information. For example, the log entry may contain "2024-12-26 16:10:00 - Successfully shut down the power supply to area A", along with other relevant information (such as current level, voltage, etc.). This not only confirms the success of the operation, but also provides valuable data support for future maintenance and troubleshooting. The central control system can review these log entries regularly, identify potential problem trends, and schedule necessary maintenance work in advance.

[0193] The above steps not only ensure a high degree of safety and reliability, but also greatly enhance the transparency and traceability of the intelligent circuit breaker control system through precise operation analysis, status feedback and detailed log records.

[0194] In addition, the existing command execution feedback mechanism is not perfect. When the intelligent circuit breaker executes the preset action, the feedback process of its status information lacks efficient security measures, which may cause the central control system to receive inaccurate or tampered information, affecting subsequent operational decisions. Moreover, there are obvious deficiencies in log recording and maintenance management. Traditional log recording is often centralized, which is not only susceptible to single point failures, but also lacks the characteristics of being tamper-proof, making it difficult to ensure the authenticity and integrity of historical data.

[0195] Based on this, the present invention provides an embodiment, according to step 105, the log entries are stored using blockchain technology, predictive maintenance processing is performed on historical log data based on a time series analysis algorithm, and the operation consistency among multiple central control systems is coordinated through a consensus algorithm under a distributed decision-making framework to generate an unalterable and distributed maintenance and control record, which specifically includes the following steps:

[0196] Step 701: Using blockchain technology, the log entries are subjected to distributed storage processing that cannot be tampered with, to obtain stored log records;

[0197] In this step, time series analysis is a statistical method used to extract patterns and trends from time-ordered data sets to help predict future behavior or status. This analysis can detect potential problems in advance and support preventive maintenance.

[0198] The cleaned log data is processed through a time series analysis algorithm to identify patterns and trends. This includes analyzing factors such as operation frequency, failure rate, and equipment performance changes to predict potential problems in the future. Based on the analysis results, the system generates predictive maintenance information to guide the maintenance team to take appropriate preventive measures to avoid sudden failures.

[0199] Continuing with the previous embodiment, the cleaned log data is input into the time series analysis algorithm. For example, it is found that the circuit breakers in a specific area frequently trigger the protection mechanism within a specific time period, indicating that there may be potential faults. Through further analysis, predictive maintenance information is generated, and the maintenance team is advised to conduct a detailed inspection of the circuit breakers in the area during the next maintenance cycle, which helps to solve the problem in advance and reduce the risk of unexpected downtime.

[0200] Step 702: Clean and format the stored log records to remove redundant or incomplete records, and obtain cleaned log data;

[0201] In this step, the stored log records are cleaned and formatted to remove redundant or incomplete records to obtain cleaned log data. Data cleaning involves operations such as identifying and correcting errors, filling missing values, and deleting duplicate records to ensure data quality and consistency. Formatting ensures that all data follows a unified standard to facilitate subsequent analysis and processing.

[0202] After storage, log records undergo a series of data cleaning and formatting operations, including checking data integrity, deleting redundant or incomplete records, and correcting erroneous information, to ensure that the final cleaned log data is accurate, consistent, and easy to analyze. The formatted log data is usually converted into a standardized file format (such as CSV, JSON) for subsequent processing;

[0203] Continuing with the implementation example of the previous step, the log records on the blockchain undergo regular data cleaning and formatting. For example, the timestamp, operation content, and result fields of each log record are automatically checked for completeness, and duplicate or incomplete records are deleted. Data with obvious errors (such as abnormal timestamps or unreasonable results) will be marked and processed. After cleaning and formatting, the cleaned log data generated can be more efficiently used for subsequent analysis and prediction work.

[0204] Step 703: Analyze the cleaned log data based on a time series analysis algorithm, identify potential failure modes and trends, and generate predictive maintenance information;

[0205] In this step, the cleaned log data is analyzed based on a time series analysis algorithm to identify potential failure modes and trends and generate predictive maintenance information. Time series analysis is a statistical method used to extract patterns and trends from time-ordered data sets to help predict future behaviors or states. This analysis can detect potential problems in advance and support preventive maintenance.

[0206] The cleaned log data is processed through a time series analysis algorithm to identify patterns and trends. This includes analyzing factors such as operation frequency, failure rate, and equipment performance changes to predict potential problems in the future. Based on the analysis results, predictive maintenance information is generated to guide the maintenance team to take appropriate preventive measures to avoid sudden failures.

[0207] Continuing with the previous embodiment, the cleaned log data is input into the time series analysis algorithm. For example, it may be found that the circuit breakers in a specific area frequently trigger the protection mechanism within a specific time period, indicating that there may be potential faults. Through further analysis, predictive maintenance information is generated, and the maintenance team is advised to conduct a detailed inspection of the circuit breakers in the area during the next maintenance cycle. This helps to solve the problem in advance and reduce the risk of unexpected downtime.

[0208] Step 704: Under the distributed decision-making framework, coordinate the operational consistency among multiple central control systems through a consensus algorithm, and adjust the operational strategies among multiple central control systems based on the predictive maintenance information to generate an unalterable and distributed maintenance and control record.

[0209] In this step, the consensus algorithm ensures the consistency of operations between different nodes and maintains the reliability of the distributed system. The adjusted operation strategy is based on predictive maintenance information, aiming to optimize system operation and improve maintenance efficiency.

[0210] Multiple central control systems reach operational consistency through consensus algorithms (such as PBFT, Raft, etc.) to ensure that the operation strategies of all nodes are synchronized. Based on predictive maintenance information, the operation strategies of each central control are dynamically adjusted, such as giving priority to maintenance tasks in high-risk areas or optimizing resource allocation. All adjusted operation records are also stored through blockchain technology to ensure their immutability and distribution.

[0211] Continuing with the previous implementation example, multiple central control systems coordinate operating strategies through consensus algorithms to ensure the consistency of all nodes. For example, when predictive maintenance information indicates that a certain area requires emergency maintenance, all relevant control systems will synchronously adjust the operating strategies to prioritize the maintenance tasks in that area. The adjusted operating strategies and execution results are stored again through blockchain technology to generate tamper-proof and distributed maintenance and control records, which improves the overall response speed, ensures the authenticity and traceability of all operating records, and supports long-term historical data analysis and optimized decision-making.
