[0041] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0042] It should be noted that the fault handling method of the smart home device provided by the present application is generally executed by the smart home gateway, and accordingly, the fault handling device of the smart home device is generally provided in the smart home gateway.

[0043] Figure 1 An exemplary system architecture of the fault processing method or the fault processing device of the smart home device applicable to the present application is shown.

[0044] As shown in Figure 1 The smart home system can include: a cloud server 0, a plurality of smart home gateways 1-n, and a plurality of smart home devices managed by each smart home gateway, n is an integer greater than 1. The cloud server and the smart home gateway, and the smart home gateway and the smart home device can communicate through a network, which is a medium for providing communication links between the above-mentioned units. The network can include various types of wired communication links or wireless communication links, such as: wired communication links include optical fiber, twisted pair or coaxial cable, etc., wireless communication links include Bluetooth communication link, wireless fidelity (Wireless-Fidelity, Wi-Fi) communication link or microwave communication link, etc.

[0045] Among them, the number of cloud servers 0 can be one or more, when the number of cloud servers is more, the plurality of servers form a distributed server cluster. The cloud server as the data storage center of the smart home system is responsible for centralized storage of all smart home device running data, user configuration information, historical records, etc. With powerful computing power, these data are processed and analyzed to provide users with remote monitoring, data analysis, fault warning, etc. Services of smart home devices. Users can access the cloud server through the Internet to realize remote control and management of smart home devices. The cloud server provides a unified interface and protocol, so that users can view and control the status of smart home devices at any time and anywhere through mobile phone APP, web page, etc. Client. The cloud server is responsible for user information registration, login, permission allocation, etc. Through user authentication and authorization mechanism, only legal users can access and control smart home devices to ensure the security of the system. The cloud server is responsible for software update and version management of the smart home system to ensure that the system is always in the latest state. It also provides remote technical support and maintenance services to help users solve the problems encountered in the use of smart home devices. The smart home gateway and the plurality of smart home devices managed thereby constitute a user's smart home network.

[0046] Functions of the smart home gateway: The smart home gateway, as the hub of the smart home system, can centrally manage multiple smart home devices. Through a unified communication protocol and interface, it realizes connection and communication with smart home devices, ensuring interconnection between devices. The smart home gateway is responsible for forwarding the operation data of smart home devices to the cloud server for storage and processing. At the same time, it can also perform local processing and analysis of device data, providing real-time device status monitoring and fault warning for users. The smart home gateway supports users to remotely control smart home devices through the cloud server. It can also cooperate with the cloud server to realize functions such as remote configuration, upgrade and troubleshooting of devices. The smart home gateway supports users to set multiple scene modes, such as away mode, home mode, sleep mode, etc. Users can realize automatic control and linkage of multiple smart home devices through one-key operation. The smart home gateway ensures the security and privacy protection of the smart home system through encrypted communication and identity verification mechanism. It can also monitor the home environment in real time, and automatically alarm and notify users if abnormal conditions are found.

[0047] Functions of smart home devices: Smart home devices can receive control instructions from the smart home gateway or the cloud server, realizing functions such as switching, adjusting, and linkage of devices. At the same time, they can also monitor their own running status and environmental parameters in real time, and report the data to the smart home gateway or the cloud server. Smart home devices realize intelligent control and automatic operation through built-in sensors and actuators. For example, smart lighting devices can automatically adjust brightness according to light intensity and time; smart security devices can automatically alarm and notify users when detecting abnormal conditions. Smart home devices are usually equipped with display screens, indicator lights, sound prompts, and other interactive interfaces to facilitate users to understand the running status of the devices and perform manual control. They can also be connected with smart phones, smart speakers, and other devices to realize voice control, remote control, and other more convenient interaction methods. Through intelligent control and automatic operation, smart home devices realize efficient use and conservation of energy. For example, smart air conditioners can automatically adjust the working mode according to indoor temperature and humidity; smart curtains can automatically open and close according to light intensity and time.

[0048] It should be noted that the cloud server 0 and the smart home gateways 1-n of the users constitute the blockchain nodes of the blockchain network.

[0049] It should be understood that Figure 1 The number of cloud servers, smart home gateways and smart home devices in the above description is only illustrative. According to the needs of implementation, it can be any number.

[0050] The following will be described in conjunction with the accompanying Figure 2The method for processing the fault of the smart home device provided in the embodiment of the application is introduced in detail. The fault processing device of the smart home device in the embodiment of the application can be the smart home gateway shown in Figure 1 .

[0051] Please refer to Figure 2 , a flowchart of the method for processing the fault of the smart home device provided in the embodiment of the application is provided. As shown in Figure 2 , the method provided in the embodiment of the application can include the following steps:

[0052] S201, detecting the working state of the smart home device in real time.

[0053] The smart home gateway device detects the working state of the smart home device in real time in the following ways:

[0054] Active polling: the smart home gateway device regularly sends a state query request to each smart home device, and the device returns the current state information after receiving the request. This method is suitable for all devices that support active reporting of the state.

[0055] Event-driven: the smart home device actively sends a state update message to the smart home gateway device when the state changes. This method requires that the device has the ability of event triggering and message pushing.

[0056] When performing state detection, the smart home gateway device also analyzes and evaluates the returned state information according to the type, function of the device and the preset monitoring rules, to determine whether the device is in a normal working state.

[0057] In some embodiments of the application, the method for detecting the working state of the smart home device by the smart home gateway device includes:

[0058] detecting whether the smart home device is online, if yes, determining that the smart home device is in a normal state, if no, determining that the smart home device is in an abnormal state; or

[0059] detecting whether the running parameter of the smart home device is within a preset range, if yes, determining that the smart home device is in a normal state, if no, determining that the smart home device is in an abnormal state; or

[0060] detecting whether the smart home device reports an error code, if yes, determining that the smart home device is in an abnormal state, if no, determining that the smart home device is in a normal state.

[0061] The smart home gateway device is the core component of the smart home system, and is responsible for detecting the working state of each smart home device in real time. The following are several specific methods for the smart home gateway device to detect the working state of the smart home device.

[0062] 1. Detecting whether a smart home device is online:

[0063] The smart home gateway device periodically sends heartbeat packets or status query requests to the smart home device and waits for its response. If the smart home device successfully responds within a preset time, the smart home gateway device will determine that the device is online and thus preliminarily judge that it is in a normal state. If the smart home device fails to respond within the preset time, the smart home gateway device will mark the device as offline and preliminarily judge that it may be in an abnormal state.

[0064] 2. Detecting whether the operating parameters of a smart home device are within the preset range:

[0065] The smart home gateway device regularly or in real-time receives the operating parameters (such as temperature, humidity, power, signal strength, etc.) of the smart home device according to its type and the preset monitoring rules. The smart home gateway device compares these operating parameters with the preset normal range. If the operating parameters are within the preset range, the smart home gateway device will determine that the device is in a normal state. If the operating parameters exceed the preset range, the smart home gateway device will mark the device as an abnormal state and may need further investigation or corrective measures.

[0066] 3. Detecting whether a smart home device reports error codes:

[0067] When a smart home device encounters a fault or anomaly, it usually generates and reports error codes to the smart home gateway device. The smart home gateway device listens to the error code reporting channel and receives error codes sent by the smart home device in real-time. If the smart home gateway device receives error codes, it will immediately mark the device as an abnormal state and take appropriate handling measures according to the type and severity of the error codes. If the smart home gateway device does not receive any error code reports within a period of time, it will preliminarily judge that the device is in a normal state.

[0068] It should be noted that the above three methods are not isolated, and the smart home gateway device may combine them in actual operation to more accurately determine the working state of the smart home device. For example, even if the smart home device is online and does not report error codes, if its operating parameters deviate from the preset range for a long time, the smart home gateway device may mark it as an abnormal state.

[0069] In addition, the smart home gateway device will further analyze and evaluate the detected state information according to the type, function of the smart home device and the monitoring rules set by the user to determine whether further action is needed, such as sending an alarm, recording a log or triggering an automated recovery process, etc.

[0070] S202、When the working state of the smart home device is an abnormal state, obtain the device identifier of the smart home device, and query the latest device field data in the blockchain network according to the device identifier.

[0071] Wherein, when the working state of the smart home device is detected to be abnormal, the smart home gateway device will immediately perform the following operations: the smart home gateway device extracts the device identifier from the state information of the abnormal device, which is usually a unique identifier such as MAC address, device ID or serial number. The smart home gateway device utilizes the distributed ledger feature of the blockchain network to retrieve the latest field data record related to the device in the blockchain network through a secure API interface or a specific blockchain query protocol. These data may include the maintenance history, operation log, fault report of the device and any additional information uploaded by the device or user. During the query process, the smart home gateway device will ensure that the communication with the blockchain network is secure to prevent data leakage or tampering.

[0072] Further, the smart home gateway device extracts the unique device identifier from the state information or configuration file of the abnormal device. This device identifier is usually assigned to the device at the time of factory shipment and is used to uniquely identify the device in the blockchain network. The hardware identifier is a unique identifier such as MAC address, serial number, device ID, etc. that is assigned to the device at the time of factory shipment and is used to uniquely identify the device in the blockchain network. In addition to the hardware identifier, if the smart home device supports user login function (such as smart door lock, smart camera, etc.), the smart gateway will also obtain the identifier of the current login user. The user identifier may be a username, user ID or unique identifier of the user device, which is used to associate the device with a specific user in order to provide personalized services or perform permission verification when needed.

[0073] In the blockchain network, blockchain nodes play a crucial role. These nodes include cloud servers and all users' smart home gateway devices, which jointly maintain the distributed ledger of the blockchain, ensuring data's non-tamperability and traceability.

[0074] Each blockchain node uses the IPFS (InterPlanetary File System) protocol for data reading and writing. IPFS is a distributed file system that uses content addressing to store and retrieve files. Unlike traditional location-based file systems, IPFS generates a unique address for a file by calculating its hash value, which users can use to access the file. In the blockchain network, the IPFS protocol enables each node to efficiently share and access data without worrying about data loss or tampering.

[0075] The smart home gateway device will construct a query request containing device identification, query conditions, and timestamp information based on the device identification and query requirements. The smart home gateway device sends the constructed query request to other nodes in the blockchain network through the IPFS protocol. These nodes will receive the query request and perform matching and retrieval based on their internal blockchain data. Other nodes in the blockchain network will search for relevant device field data in their respective blockchain ledgers based on the device identification and query conditions in the query request. Once the matching data is found, these nodes will return the data to the smart home gateway device through the IPFS protocol. After receiving the query results from multiple nodes, the smart home gateway device will verify and integrate the data. It will check whether the hash value of the data is consistent with the original data to ensure that the data has not been tampered with during transmission. At the same time, the smart home gateway device will also sort and integrate the data based on the timestamp and priority information of the data to obtain the latest device field data.

[0076] In some embodiments of the present application, if the working state of the smart home device is normal, the device field data of the smart home device is collected, it is judged whether the device field data collected this time and the device field data collected last time have been updated, and if yes, the device field data collected this time is written into the blockchain network.

[0077] Among them, the smart home gateway sends a data request to the smart home device, requiring the device to provide the current field data. The smart home device responds to the data request and sends the field data to the smart home gateway. After receiving the data, the smart home gateway performs analysis and preprocessing to ensure the accuracy and readability of the data.

[0078] The smart home gateway compares the current collected data with the last collected data. The comparison can involve changes in individual data points, analysis of data trends, or judgment of data ranges, etc. According to the comparison result, the smart home gateway judges whether the data has changed significantly or reached the preset update condition. These conditions may include data change threshold, data update frequency or other rules set by the user. If the data meets the update condition, the smart home gateway formats the current collected data into a format suitable for blockchain storage. This may include converting the data into a specific data structure, adding a timestamp, generating a data digest or signature, etc. In order to protect the privacy and security of the data, the smart home gateway will encrypt the data before writing it to the blockchain. At the same time, the smart home gateway also generates a unique hash value as the unique identifier of the data to ensure the integrity and non-tamperability of the data. The smart home gateway selects a suitable consensus mechanism according to the type of the blockchain network (such as public chain, private chain or consortium chain) for data writing. The smart home gateway submits the encrypted data and its hash value to the nodes in the network through the interface of the blockchain network. The nodes in the blockchain network will verify the legality and validity of the data, and write the data to the blockchain through the consensus mechanism. Once the data is successfully written, the smart home gateway will receive a write confirmation message. The smart home gateway synchronizes data with other nodes to ensure that the data on all nodes is consistent. At the same time, the smart home gateway also regularly checks the data on the blockchain to ensure the accuracy and integrity of the data.

[0079] Further, in some embodiments of the present application, the smart home device encrypts the device field data before sending it to the smart home gateway, and the encryption process includes:

[0080] The smart home device collects device field data when it receives a data request from the smart home gateway;

[0081] The smart home device encrypts the device field data in plaintext form using the AES key to obtain the first ciphertext;

[0082] The smart home device encrypts the first ciphertext using the public key to obtain the second ciphertext;

[0083] The smart home device uses the private key to sign the first ciphertext and the second ciphertext to obtain the digital signature;

[0084] The smart home device packages the first ciphertext, the second ciphertext and the digital signature into a data response, and sends the data response to the smart home gateway.

[0085] The smart home gateway confirms that the working state of the smart home device is normal, and sends a data request to the device. After receiving the data request from the smart home gateway, the smart home device starts collecting on-site data of the device.

[0086] The smart home device encrypts the on-site data of the device in plaintext form using a pre-configured AES key to obtain a first ciphertext. AES (Advanced Encryption Standard) is a widely used symmetric encryption algorithm that can provide high data encryption strength. To further enhance the security of the data, the smart home device re-encrypts the first ciphertext using a public key in asymmetric encryption to obtain a second ciphertext. Public key encryption ensures that only the recipient holding the corresponding private key can decrypt the data. The smart home device also uses its own private key to sign the first ciphertext and the second ciphertext to generate a digital signature. The role of the digital signature is to verify the integrity of the data and the identity of the sender, ensuring that the data has not been tampered with during transmission. The smart home device packages the first ciphertext, the second ciphertext and the generated digital signature into a complete data response. The smart home device sends the packaged data response to the smart home gateway through a secure communication protocol (such as HTTPS, TLS, etc.).

[0087] After receiving the data response sent by the smart home device, the smart home gateway performs unpacking processing to extract the first ciphertext, the second ciphertext and the digital signature. The smart home gateway verifies the digital signature using the public key of the smart home device to confirm the integrity of the data and the identity of the sender. If the digital signature verification is passed, the smart home gateway uses its own private key and AES key to decrypt the second ciphertext and the first ciphertext to restore the on-site data of the device in plaintext form.

[0088] S203, verify whether the queried on-site data of the device is tampered with.

[0089] Among them, after the smart home gateway device obtains the on-site data of the device on the blockchain, the following verification steps will be performed:

[0090] Hash verification: The smart home gateway device calculates the hash value of the received data and compares it with the original hash value stored on the blockchain. If they are consistent, it means that the data has not been tampered with during transmission.

[0091] Timestamp verification: The smart home gateway device checks the timestamp of the data to ensure that the data is up-to-date and has not been modified back. The verification of the timestamp helps to identify any possible data rollback or tampering behavior.

[0092] Consensus mechanism verification: In a blockchain network, data is verified and confirmed through a consensus mechanism. The smart home gateway device can verify the consensus status of the data to ensure that it is confirmed by multiple nodes in the network, thereby increasing the credibility of the data.

[0093] S204, if no, send the device field data to the smart home device, and instruct the smart home device to recover to the normal state according to the device field data.

[0094] If it is verified that the device field data has not been tampered with and is the latest valid data, the smart home gateway device will perform the following operations: the smart home gateway device sends the device field data back to the corresponding smart home device through a secure channel (such as an encrypted communication protocol). The smart home gateway device sends a series of recovery instructions to the smart home device according to the content of the device field data. These instructions may include adjusting device parameters, restarting the device, performing a self-diagnosis program, or requesting user intervention, etc. The smart home gateway device will continuously monitor the response and subsequent state changes of the smart home device to ensure that the device can successfully recover to a normal working state. If any problems occur during the recovery process or the device state does not improve, the smart home gateway device will record error information and may trigger further troubleshooting or notify the user for intervention.

[0095] Embodiments of the present application specifically include the following benefits:

[0096] By real-time detection of the working state of the smart home device, the abnormal state of the device can be quickly identified, thereby triggering the subsequent processing flow in a timely manner. This helps to reduce the service interruption time caused by device failure, and improves the convenience and safety of home life. By using the blockchain network to store and query the latest device field data, the data is ensured to be tamper-proof and highly reliable. The distributed ledger feature of the blockchain technology makes it difficult for data to be maliciously modified once recorded, providing reliable data support for subsequent device state recovery. After verifying that the device field data has not been tampered with, the data can be automatically sent to the smart home device and instructed to recover to a normal state according to these data. This intelligent recovery mechanism not only improves the efficiency of fault handling, but also reduces the need for manual intervention, making the management of home devices more convenient and intelligent. By introducing real-time monitoring, data verification and intelligent recovery mechanisms, the overall reliability and stability of the smart home system are effectively improved. This helps to promote the further development and popularization of smart home technology, and provides strong support for building a more intelligent, convenient and safe home environment.
