[0031] Example 1

[0032] The method embodiment provided in Embodiment 1 of this application can be executed in a server, controller, or similar device management device. Taking running on a server as an example, Figure 1 This is a hardware structure block diagram of a server according to an embodiment of the present invention. Figure 1 As shown, a server may include one or more ( Figure 1Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. Optionally, the server may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the server described above. For example, the server may also include components that are more complex than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0033] The memory 104 can be used to store server programs, such as application software programs and modules, like the server program corresponding to a control method for an IoT device in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the server program stored in the memory 104, thus implementing the aforementioned method. The memory 104 may include high-speed random access memory and non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the server via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0034] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the server's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0035] This embodiment provides a control method for an Internet of Things (IoT) device. Figure 2 This is a flowchart of a control method for an Internet of Things (IoT) device according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0036] Step S202: Receive a control request for the target IoT device sent by the user terminal;

[0037] The target IoT device in this embodiment can be any device that can be remotely controlled via the cloud, such as smart home appliances, such as air conditioners, refrigerators, washing machines, televisions, cameras, etc.

[0038] Step S204: Obtain the current device status of the target IoT device and the user permission information of the user terminal;

[0039] The current device status in this embodiment includes on / off status, operating mode, etc. The user permission information of the user terminal in this embodiment is used to characterize the scope of operation of the user terminal in controlling the target IoT device, such as allowing Class 1 operations on the target IoT device and disallowing Class 2 operations, etc.

[0040] Step S206: Send a control command to the target IoT device based on the current device status and the user permission information.

[0041] Optionally, the control command can be the command corresponding to the control request mentioned above, or it can be other commands that do not correspond to it.

[0042] In one example, historical control requests for the target IoT device are retrieved. These historical control requests are control requests from a preset duration prior to the current time. The system determines whether the operation types of the current control request and the historical control request are the same. If they are different, a control command is sent to the target IoT device based on the current device state and the user permission information. If they are the same, the system retrieves the historical permission range of the authorized object that triggered the historical control request and determines whether this historical permission range is greater than the user terminal's permission range. If the historical permission range is greater than the user terminal's permission range, sending control commands to the target IoT device based on the current device state and the user permission information is prohibited. If the historical permission range is less than the user terminal's permission range, sending control commands to the target IoT device based on the current device state and the user permission information is permitted. For example, if both User 1 and User 2 want to adjust the air conditioner temperature, and User 1 has greater permissions than User 2, then for a period of time after User 1 adjusts the air conditioner temperature, User 2, who has lower permissions, is not allowed to adjust the user's temperature.

[0043] Through the above steps, a decentralized device control scheme is implemented, which receives control requests from user terminals for target IoT devices; obtains the current device status of the target IoT device and the user permission information of the user terminal; and sends control commands to the target IoT device based on the current device status and the user permission information. This allows any authorized entity to remotely control IoT devices, improving the stability of smart home systems, preventing single-point failures from paralyzing the entire system, and solving the technical problem of system instability caused by centralized control models in related technologies. Furthermore, issuing commands based on the current device status and user permission information protects user privacy and device security, enhancing the user experience.

[0044] Figure 3 This is a schematic diagram of the architecture of an embodiment of the present invention, including: a cloud server: responsible for storing information such as the control logic and user permissions of smart home appliances, and providing a remote control interface. Smart home appliances: equipped with built-in communication and control modules, transmitting data and executing control commands with the cloud server. User terminals: such as mobile apps, web pages, tablets, or mini-programs, used by users to remotely send control requests and receive device status information. For example, if a user issues a control command on the app, the app calls the server's interface to transmit the command. After receiving the device command, the server checks the database for the appropriate app's user information and whether the target device exists and is functioning correctly. If everything is correct, the server sends the command to the home appliance for execution. The device, with its built-in communication and control modules, directly receives the command and returns the execution result to the server. The server then returns the result to the app, and the app notifies the user.

[0045] In one embodiment of this example, sending a control command to the target IoT device based on the current device status and the user permission information includes: determining the permission scope of the user terminal based on the user permission information; parsing the request instruction of the control request; determining whether the permission scope includes the permission to issue the request instruction; and if the permission scope includes the permission to issue the request instruction, sending a control command to the target IoT device based on the current device status.

[0046] In one example, the user terminal's permission scope includes allowing control of devices A and B for operations of types 1 to 5, and allowing control of device C for operations of type 2. These operations include various types such as temperature control, mode control, on / off control, scheduled control, and device deregistration. The request instruction for the control request is used to indicate specific operation instructions, such as lowering the temperature or switching modes. If the user terminal is device A and the request instruction is a type 1 operation, then the permission scope includes the permission to issue the request instruction, and the user terminal can respond to the control request from the user terminal and send control instructions to the target IoT device.

[0047] Based on this implementation, only when the user terminal's permission scope includes the permission to issue the request instruction, can the control instruction be sent to the target IoT device based on the current device status, thus ensuring device security and preventing unfamiliar devices from arbitrarily controlling the target IoT device.

[0048] In one example, sending a control instruction to the target IoT device based on the current device state includes: determining a basic state set that the target IoT device supports the request instruction; determining whether the basic state set includes the current device state; and if the basic state set includes the current device state, sending the request instruction to the target IoT device, wherein the control instruction includes the request instruction.

[0049] In this example, the basic state set includes multiple basic states. The target IoT device can only respond to the request command normally when its current device state is in a basic state. For example, it can only respond to the power-on command when it is in standby mode, the mode selection command when it is in power-on mode, and the anti-direct-blow command when it is in cooling mode. If the target IoT device's current device state is not in the basic state set, the target IoT device cannot directly respond to the request command, and the request command is invalid at this time.

[0050] Using the solution in this example, when the target IoT device supports the request instruction's basic state set including the current device state, the request instruction is sent to the target IoT device, ensuring the validity of the control request and improving the device's control efficiency.

[0051] In another example, after determining whether the basic state set contains the current device state, the method further includes: if the basic state set does not contain the current device state, searching in the basic state set for the target state that best matches the request instruction; sending a state switching instruction to the target IoT device, wherein the state switching instruction is used to switch the target IoT device from the current device state to the target state; after the target IoT device switches to the target state, sending the request instruction to the target IoT device, wherein the control instruction includes the state switching instruction and the request instruction.

[0052] Optionally, if the set of basic states supporting the request instruction contains only one basic state, then that basic state is determined as the target state that best matches the request instruction. If the set of basic states contains multiple optional basic states, then the best matching target state can be determined based on environmental parameters, big data model prediction, or other methods.

[0053] For example, to control a target IoT device, the device must be powered on. If the device is powered off, a power-on command must be sent first, followed by the control request command. In some implementation scenarios, the target IoT device is an air conditioner with an anti-direct-blow function, but this function only works in cooling mode. If the current device mode is ventilation, and the user sends a control request to activate the anti-direct-blow function, the server will first send a state-switching command to activate cooling mode, and then send the command to activate the anti-direct-blow function. In other words, if the current device state does not support the command, the device state is changed first to ensure the command is executed effectively.

[0054] Using the solution in this example, even if the target IoT device's basic state set supporting the request instruction does not include the current device state, the device can still indirectly respond to the control request by controlling the device state, avoiding multiple user operations and improving the device's control efficiency.

[0055] In another embodiment of this example, after determining whether the scope of permissions includes the permission to issue the request instruction, the method further includes: if the scope of permissions does not include the permission to issue the request instruction, searching within the scope of permissions for a set of recommended instructions with the same control type as the permission to issue the instruction; returning the set of recommended instructions to the user terminal; receiving the target recommended instruction selected by the user terminal from the set of recommended instructions; and sending the target recommended instruction to the target IoT device.

[0056] In this implementation, the user terminal's permission scope includes allowing control of devices A and B for operations of types 1 to 5, and allowing control of device C for operations of type 2. These include various types of operations such as temperature control, mode control, on / off control, scheduled control, and device deregistration. The request instruction for the control request is used to indicate specific operation instructions, such as lowering the temperature or switching modes. If the user terminal is device C and the request instruction is a type 1 operation, the permission scope does not include the permission to issue the requested instruction. Instead, a recommended instruction set belonging to type 2 operations can be returned to the user terminal. The user selects one and notifies the server, which then issues the instruction to device C. In one implementation scenario, device C is an air conditioner. Type 1 operations are shutdown instructions, and type 2 operations are temperature adjustment instructions. The recommended instruction set includes temperature increase instructions and temperature decrease instructions (but not shutdown instructions or other types of operation instructions besides temperature adjustment instructions). Within their own permissions, the user can adjust the air conditioner to their preferred state according to their actual needs.

[0057] Based on this implementation, when the user terminal's permission scope does not include the permission to issue the requested instruction, by returning a set of recommended instructions within its permission scope to the user terminal, the user can adjust the air conditioner to their desired state according to their actual needs within the user terminal's permissions, thereby improving the user experience.

[0058] Optionally, obtaining the user permission information of the user terminal includes: reading the user account logged in on the user terminal, obtaining the type of software installed on the user terminal, and reading the network information of the user terminal; and determining the user permission information of the user terminal based on the user account, the software type, and the network information.

[0059] Optionally, software types include operating systems (such as Xiaomi speakers, Baidu speakers, etc.), applications (APPs), mini programs, and official accounts on the local area network control terminal. The network information of the user terminal is used to indicate whether the user terminal is connected to the same local area network as the target IoT device.

[0060] The solution in this embodiment uses multiple dimensions of information, such as the user account, software type, and network information, to configure the user permission information of the user terminal, thereby achieving fine-grained configuration of user permissions. Through permission hierarchy, the security of the device and the user experience are improved.

[0061] In this embodiment, before receiving the control request for the target IoT device sent by the user terminal, the method further includes: receiving the registration request of the target IoT device; responding to the registration request, assigning a device identifier to the target IoT device, loading the device control model of the target IoT device, and configuring the device permission information of the target IoT device, wherein the device permission information includes the permission scope of all authorized objects that are allowed to control the target IoT device.

[0062] Optionally, the device control model is used to decode and convert relevant interaction commands for the target IoT device, and also includes the device's control logic. For example, an air conditioner's control logic includes power on / off, temperature adjustment, mode adjustment, fan speed adjustment, and airflow mode adjustment. Authorized objects include authorized terminals, authorized accounts, and authorized software. Device permission information includes the permission scope of the authorized terminal, authorized account, and authorized software. For example, a mobile app logs in using a username, password, or verification code to ensure the user is a legitimate network user. After successful user authentication, the cloud checks whether the user has permission to perform specific operations, which can be done by querying the user's account role or access control list. Device identification includes the target IoT device's device name, model, icon, and other information.

[0063] The solution in this embodiment achieves decentralized control of IoT devices by pre-registering the target IoT device to the cloud and configuring and assigning permissions to it, allowing any participant to submit a control request.

[0064] Figure 4 This is a flowchart illustrating an embodiment of the present invention. The present invention proposes a cloud-based decentralized remote control system and method for home appliances. Through a decentralized control mode and advanced security measures, it solves the problems existing in current smart home systems, improving system stability, security, and user experience. When a new device joins the system, it needs to register through the cloud and obtain a unique device identifier. User terminals can discover and connect to registered devices through the cloud. The cloud server is responsible for user permission management, ensuring that only authorized users can control the devices. Functions such as user registration, login, and permission allocation are provided.

[0065] Each smart home appliance possesses independent communication and control capabilities, independent of a central controller. Devices exchange information and collaborate via a cloud server, achieving decentralized control. Users send control requests to the cloud through their terminals, and the cloud issues control commands to designated devices based on device status and user permissions. A standardized communication protocol and rules ensure secure and reliable data transmission between devices and between devices and the cloud. Encryption technology protects the transmission of user data and control commands, selecting different encryption technologies for different scenarios. For example, symmetric encryption algorithms such as AES can be used for applications requiring high-speed data transmission; while asymmetric encryption algorithms such as RSA can be used for scenarios requiring higher security. For IoT devices with resource limitations (such as limited computing power and storage space), lightweight encryption algorithms are used. These algorithms have lower computational complexity and memory footprint, meeting the efficiency requirements of IoT devices while ensuring security. Authentication is performed between user terminals and home appliances to prevent unauthorized access.

[0066] This embodiment proposes a cloud-based decentralized smart home system and its control method, solving the problem of system paralysis caused by a single point of failure. It reduces the risk of data tampering or misuse in centralized structures, improves the stability of the smart home system, and avoids system paralysis due to a single point of failure. It also enhances the security of the smart home system, protecting user privacy and device security. Finally, it improves the user experience, enabling users to more conveniently remotely control home appliances.

[0067] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.
