[0030] In this embodiment, a cross-platform device control method running on a cloud platform is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 2 is a flow chart of a cross-platform device control method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0032] Step S201: receiving a general intelligent device control request; for example, turning on the air conditioner in the living room and setting the temperature to 24 degrees; turning on the air conditioner in the master bedroom and setting the temperature to 26 degrees; turning on the sweeping robot in the living room and sweeping the master bedroom;

[0033] Specifically, receiving the above-mentioned smart device control request sent by the user terminal through the blockchain network; wherein the user terminal may be a smart phone or other terminal device;

[0034] Among them, blockchain technology is a distributed database technology that allows multiple participants to share, store and confirm transaction information in an immutable, secure and transparent database. The core features of blockchain technology include decentralization, immutability, traceability and transparency. The following are some key concepts and features of blockchain technology:

[0035] 1. Decentralization: The blockchain network does not rely on a single centralized authority or server, but is maintained by multiple nodes distributed around the world. This makes the network more robust and less susceptible to single point failures.

[0036] 2. Immutability: Once data is added to the blockchain, it is almost impossible to change or delete it. This is because each block contains the hash value of the previous block, forming a chain structure. Any change to the historical record will cause the hash value of all subsequent blocks to change, which can be detected by other participants in the network.

[0037] 3. Traceability: Every transaction on the blockchain is public and can be queried through a blockchain browser. This facilitates auditing and supervision, while also increasing the transparency of transactions.

[0038] 4. Transparency: Although the participants in the transaction can remain anonymous, all transaction records are public and anyone can view the transaction history on the blockchain.

[0039] 5. Encryption technology: Blockchain uses advanced encryption technology to protect the security of transaction data. The pairing of public and private keys ensures that only users with the correct private key can access the assets in their accounts.

[0040] 6. Consensus mechanism: Nodes in the blockchain network need to reach a consensus on the addition of new blocks. Common consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS).

[0041] 7. Smart Contracts: Smart contracts are programs stored on the blockchain that execute automatically when preset conditions are met. This enables complex transactions and agreements to be executed without intermediaries.

[0042] 8. Scalability: With the development of technology, blockchain networks are constantly being optimized to handle more transactions and more complex application scenarios.

[0043] Step S202: parsing the general smart device control request to obtain relevant information of the smart device to be controlled, wherein the relevant information includes the device type and model;

[0044] For example, the types of smart devices to be controlled are smart speakers, smart lighting, smart thermostats, smart door locks, smart refrigerators, smart washing machines and dryers, smart TVs, smart sweeping robots, smart air conditioners, smart kitchen appliances, smart curtains, and smart sockets, etc.

[0045] Specifically, the device model of the to-be-controlled smart device is set by different manufacturers when the devices are shipped out of the factory, and the same type of controlled smart device has at least one model.

[0046] Specifically, step S202: parsing the above-mentioned universal smart device control request to obtain relevant information of the smart device to be controlled, including:

[0047] Step S2021: parsing the universal smart device control request to obtain device description information;

[0048] For example, if the general smart device control request is "turn on the air conditioner in the living room and set the temperature to 24 degrees", the device description information obtained by parsing is the air conditioner in the living room;

[0049] Step S2022: Based on the above device description information, match the device registration information on the blockchain to obtain the relevant information of the above smart device to be controlled.

[0050] That is to say, the device information of multiple types and multiple signals of different brands has been registered on the blockchain in advance, and the information of smart devices in multiple houses in the house has been uploaded, so after matching according to the device description information, the type, model, manufacturer and other information of the air conditioner in the living room can be obtained.

[0051] Step S203: Based on the above relevant information, a smart contract is used to convert the above general smart device control request into a control instruction that complies with the control instruction specification of the above smart device to be controlled, and the above control instruction is sent to the above smart device to be controlled through the blockchain network to perform corresponding control on the above smart device to be controlled.

[0052] Among them, smart contracts are the core of blockchain technology and are configured in advance. The application of smart contracts can convert general smart device control requests into instructions in a format that can be recognized by the smart device to be controlled, so as to achieve control of the smart device to be controlled.

[0053] The cross-platform device control method of the present application is applied, by receiving a general intelligent device control request; parsing the general intelligent device control request to obtain relevant information of the intelligent device to be controlled, the relevant information including the device type and device model; based on the relevant information, a smart contract is used to convert the general intelligent device control request into a control instruction that conforms to the control instruction specification of the intelligent device to be controlled, and the control instruction is sent to the intelligent device to be controlled through the blockchain network to control the intelligent device to be controlled accordingly. The use of blockchain and smart contracts to achieve cross-platform device control simplifies the process while ensuring high security due to the decentralized, tamper-proof and highly transparent characteristics of blockchain technology.

[0054] Specifically, based on the above relevant information, the above smart contract is used to convert the above general smart device control request into a control instruction that complies with the control instruction specification of the above smart device to be controlled, including:

[0055] The predefined rules configured in the above smart contract are used to convert the above general smart device control request into a control instruction that complies with the above control instruction specification of the above smart device to be controlled.

[0056] Among them, the above-mentioned predefined rules include: device type rules, device model rules, protocol conversion rules and operation logic rules. The above-mentioned device type rules represent the control instruction set corresponding to the device type, the above-mentioned device model rules represent the control instruction set corresponding to the device model, the above-mentioned protocol conversion rules represent the conversion of the protocol of the above-mentioned general smart device control request into the communication protocol used by the specific device, and the above-mentioned operation logic rules define the logic flow of specific operations. Through predefined rules, the system can standardize the control logic of various devices and reduce development and maintenance costs. Improve the scalability and compatibility of the system and support more types and models of home appliances. General control requests are converted into control instructions for specific home appliances.

[0057] In addition, the automatic conversion of general control requests is realized to reduce the complexity of user operations. The user experience is improved, allowing users to conveniently control various home appliances. The target home appliances and the required control instructions are determined through smart contracts. And the automatic execution and immutability of smart contracts are used to ensure the security and accuracy of control instructions. Function: Enhance the security and reliability of the system and avoid human intervention and erroneous operations.

[0058] In addition, before receiving the universal smart device control request, the method further includes: receiving an authentication and authorization request sent by the user terminal; and if the authentication and authorization request sent by the user terminal is deemed to be passed, determining that the user terminal has the authority to send the universal smart device control request to the cloud platform. The steps of user terminal authentication and authorization are added to increase security.

[0059] Furthermore, after converting the general smart device control request into a control instruction that complies with the control instruction specification of the smart device to be controlled by using the smart contract based on the relevant information, the method further includes: using the smart contract to sign the control instruction that complies with the control instruction specification of the smart device to be controlled and storing it on the blockchain to ensure the authenticity and immutability of the control instruction.

[0060] Furthermore, the method further includes: receiving a command execution result, the command execution result being an execution result generated after the smart device to be controlled executes the corresponding control command; and feeding back the command execution result to the user terminal. The user can intuitively see the control result of the device on the user terminal, for example, the air conditioner has been adjusted to 27 degrees.

[0061] A specific embodiment is provided below, taking "a user controls the air conditioner in the living room through a mobile phone APP" as an example, including:

[0062] User sends a request: The user enters or selects "Turn on the air conditioner in the living room and set the temperature to 24 degrees" on the mobile phone APP. The APP sends the request to the public cloud service platform.

[0063] Request parsing: The public cloud service platform receives the request and parses the device type (air conditioner), location (living room), and operation (turn on and set the temperature to 24 degrees).

[0064] Match device type and model: The public cloud service platform queries the device database and finds the device ID and model corresponding to the air conditioner in the living room.

[0065] Search for predefined rules: The public cloud service platform searches for corresponding predefined rules based on the model of the air conditioner and determines the control instruction set supported by the model.

[0066] Generate control instructions: The public cloud service platform converts general requests into specific control instructions based on predefined rules, such as "power on instruction" and "set temperature to 24 degrees instruction".

[0067] Encapsulated communication protocol: The public cloud service platform encapsulates the control instructions into a specific communication protocol format according to the air conditioner's communication method (such as Wi-Fi).

[0068] Smart contract execution: The public cloud service platform calls the smart contract through the blockchain network. The smart contract receives and parses the control request, queries the device ID, matches the predefined rules, generates and signs the control instruction, and stores it on the blockchain.

[0069] Instruction sending: The smart contract sends the signed control instructions to the target air-conditioning equipment through the blockchain network.

[0070] Execution and feedback: The air conditioning equipment receives the control command, starts up and sets the temperature to 24 degrees.

[0071] The air conditioning equipment will feed back the execution results to the blockchain network, and users can view the control results on the mobile phone APP.

[0072] The embodiment of the present application also provides a cloud platform.

[0088] The embodiment of the present invention provides a device control system, such as Figure 4 As shown, including:

[0089] The user terminal is used to send a universal smart device control request; specifically, the user initiates the universal smart device control request by operating on the user terminal;

[0090] The cloud platform (i.e., a public cloud service platform) communicates with the above-mentioned user terminal through a blockchain network, and is used to execute any of the above-mentioned cross-platform device control methods.

[0091] Among them, the blockchain network is used to store and transmit control instructions to ensure the security and transparency of data. Specifically, the blockchain network adopts the form of a public chain or a consortium chain to ensure that the data is open, transparent and cannot be tampered with. All control instructions and device status information are recorded on the blockchain in the form of transactions, and each home appliance has a unique identifier. Smart contracts are the core of blockchain technology, which automatically execute instruction conversion through pre-defined rules. Each smart contract corresponds to a home appliance control protocol, which can convert general control requests into control instructions for specific brands and types of home appliances.

[0092] More specifically, since home appliance control involves multiple parties (such as home appliance manufacturers, service providers, and users), the blockchain network uses a consortium chain to ensure data transparency and immutability while improving performance and controllability. All control instructions and device status information are recorded on the blockchain in the form of transactions, and each home appliance device has a unique identifier.

[0093] Control instruction transaction: Each control instruction is recorded as a transaction on the blockchain, containing the following information: instruction ID, user ID, device ID, control instruction content, timestamp and digital signature;

[0094] Device status transaction: Each change in device status is also recorded as a transaction on the blockchain, containing the following information: status ID, device ID, status content, timestamp and digital signature, thereby ensuring the security and accuracy of the information.

[0095] During data transmission, all data uses encryption technology (such as TLS / SSL) to ensure the confidentiality and integrity of the data. At the same time, new transactions are broadcast to all nodes through the blockchain network to ensure data consistency among all nodes.

[0096] Smart contract design includes control contracts and status contracts. The control contract is responsible for converting general control requests into control instructions for specific home appliances. Each brand or type of home appliance has a corresponding control contract. The status contract is responsible for recording and querying the status information of home appliances to ensure that the status data is transparent and cannot be tampered with.

[0097] Public cloud service platform: responsible for receiving user control requests and converting them into instructions that different home appliances can recognize through smart contracts; its main functions include: User authentication and authorization: ensuring that only authorized users can send control requests. Request parsing and distribution: parsing user control requests and converting them into specific home appliance control instructions through smart contracts. Status monitoring and feedback: real-time monitoring of the status of home appliances and recording feedback information on the blockchain.

[0098] Home appliances: receive and execute control instructions from the public cloud;

[0099] The control process of the device control system of this application to realize the control of the smart device is as follows:

[0100] Step S1: User sends a request: The user sends a home appliance control request to the public cloud service platform via a smartphone or other terminal device.

[0101] Step S2: Request parsing: The public cloud service platform parses the request and determines the target home appliance and the required control instructions through the smart contract.

[0102] Step S3: Instruction conversion: The smart contract converts the general control request into the control instruction of the specific home appliance according to the predefined rules.

[0103] The specific explanations of the predefined rules are as follows:

[0104] Predefined rules are rules and logic set by the system during the design and development phase, which are used to convert general user control requests into control instructions that can be understood and executed by specific home appliances. These rules mainly include:

[0105] Device type rules: define different control instruction sets according to device types (such as air conditioners, TVs, lights, etc.).

[0106] Device model rules: Based on the specific model of the device, define the control instructions and parameter ranges supported by the model.

[0107] Protocol conversion rules: Convert general control requests into the communication protocol used by specific devices (such as infrared, Wi-Fi, Bluetooth, etc.).

[0108] Operation logic rules: define the logic flow of a specific operation. For example, when turning on the air conditioner, you may need to send the "power on" command first, and then send the "set temperature" command.

[0109] The specific implementation process of instruction conversion is:

[0110] Parsing general smart device control requests: The control requests sent by users are usually general natural language or predefined format instructions, such as "turn on the air conditioner in the living room and set the temperature to 24 degrees."
