[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0042] The device information access method provided in this disclosure is applied to scenarios where device-related information of a target device is obtained and displayed based on a preset protocol.

[0043] For smart home devices that are part of the same ecosystem and have interconnected relationships, different devices within the device set can be managed and controlled through a pre-defined control protocol. In related technologies, the control protocol specifies corresponding control logic for each different device in the device set, and the control protocol uses standardized data types to represent and transmit device information.

[0044] In related technologies, when controlling devices through device control protocols, the data types and functions of the control protocol attributes are all simple, only representing basic information and unable to represent more complex information. This limits the applicability of the control protocol, mainly targeting simple target devices. When dealing with complex target devices, the simple data types and functions of the control protocol attributes cannot accurately express and transmit device-related information of target devices with complex functions.

[0045] In an exemplary embodiment of this disclosure, Figure 1 This is a schematic diagram illustrating a specification describing a device data model in a control protocol according to an exemplary embodiment of the present disclosure, such as... Figure 1 As shown in the diagram, the concepts represented in the ellipsis boxes are listed alongside their corresponding concepts in the adjacent boxes. For example, the ellipsis box adjacent to "module" represents other modules listed alongside "module". Figure 1 As shown, device control protocols in related technologies have a fixed device data model for device specifications. This model includes the device itself, along with its corresponding modules, services, properties, actions, and events. The properties in the device data model are dynamically changing information. Control protocols primarily use properties to represent and transmit device-related information. However, given that the data types and functions of attributes in related technologies are simple, they cannot accurately express and transmit device-related information for target devices with complex functions.

[0046] In view of this, this disclosure proposes a method for accessing device information. After receiving a data access instruction from a user, a first device determines the second device corresponding to the instruction. The first device retrieves and displays the device-related information of the second device from the cloud. The device-related information stored in the cloud is automatically uploaded by the second device. The first device, the second device, and the cloud are associated, and they interact based on a preset protocol. The device-related information is transmitted from the second device to the cloud based on the preset protocol. The preset protocol represents the device-related information through lists and structures. The device-related information represents third devices associated with the second device and the associated information for each third device. The associated information represents the interaction state between the corresponding third device and the second device. This disclosure standardizes a complex data type capable of representing complex information for the preset protocol, enabling the preset protocol to support devices with complex functions.

[0047] In an exemplary embodiment of this disclosure, Figure 2This is a schematic diagram illustrating an application scenario of a device information access method according to an exemplary embodiment of this disclosure, such as... Figure 2 As shown, the device information access method proposed in this disclosure can be applied to the following scenarios: Users use an application (APP) on their terminal to remotely interact with the device based on a preset protocol through the cloud as an information transmission channel, enabling users to view device-related information through the application on their terminal. Given that this disclosure defines complex data types that can represent complex information for the attributes in the preset protocol, the data type transmitted in the cloud channel needs to include complex data types so that users can view relatively complex device-related information through the application on their terminal.

[0048] Figure 3 This is a flowchart illustrating a device information access method applied to a first device according to an exemplary embodiment. Figure 3 As shown, the method includes the following steps.

[0049] In step S101, the first device receives a data access instruction from the user and determines the second device corresponding to the data access instruction. The data access instruction is used to request access to the device-related information of the second device. The device-related information represents the third device associated with the second device and the association information corresponding to each third device. The association information represents the interaction state between the corresponding third device and the second device.

[0050] In step S102, the first device obtains the device-related information of the second device from the cloud and displays the device-related information. The first device, the second device and the cloud are associated, and the first device, the second device and the cloud interact based on a preset protocol. The device-related information is transmitted from the second device to the cloud based on the preset protocol. The preset protocol represents the device-related information through lists and structures.

[0051] In this embodiment, after receiving a data access command from a user, the first device determines the second device corresponding to the data access command. The first device retrieves and displays the device-related information of the second device from the cloud. The device-related information stored in the cloud is the device information automatically uploaded by the second device. The first device, the second device, and the cloud are associated, and they interact based on a preset protocol. The device-related information is transmitted from the second device to the cloud based on the preset protocol. The preset protocol represents the device-related information through lists and structures. The device-related information represents the third devices associated with the second device and the associated information for each third device. The associated information represents the interaction state between the corresponding third device and the second device.

[0052] This disclosure provides a complex data type that can represent complex information for a preset protocol, enabling the preset protocol to support devices with complex functions.

[0053] In this disclosure, complex data types are added to the preset protocol from two perspectives: a list for expressing a variable amount of data, and a structure for expressing composite information. The following embodiments further illustrate the preset protocol in this disclosure.

[0054] In one embodiment of this disclosure, a list represents third devices that are associated with the second device in the device-related information, and the list represents the association information corresponding to each third device; the structure represents the association relationship between each third device and the corresponding association information.

[0055] In this embodiment of the disclosure, complex data types are added to the attributes in the preset protocol from two perspectives. The first is a data type used to represent composite information, named a structure (or struct). The second is a data type used to represent a variable quantity of data, named a list (or array). Structures and lists can be nested; that is, a structure can contain a list, and a list can contain a structure.

[0056] In this embodiment of the disclosure, when representing and transmitting device-related information using a complex data type containing structures and lists, a list representing a variable number represents a series of third devices associated with the second device, such as 0, 1, ..., n. A list also represents a series of associated information corresponding to the third devices, such as [information 1, information 2, ..., information n]. A structure representing the complex data type constructs the correspondence between the third devices and the associated information; that is, a structure represents a series of mutually corresponding third devices and associated information, such as [(device 1, information 1), (device 2, information 2), ..., (device n, information n)].

[0057] Understandably, in order to facilitate unified management of the complex information represented by complex data types, the definition of complex data types is stored in the outermost preset field (such as data-type-defs) of the device data model, and the complex information represented by complex data types is referenced in the attributes through preset methods (such as $ref).

[0058] In an exemplary embodiment of this disclosure, Figure 4 This is a schematic diagram illustrating a specification describing a device data model in a control protocol according to an exemplary embodiment of the present disclosure, such as... Figure 4As shown, the data model of the preset protocol in this disclosure includes a basic module and corresponding service information. The basic module is a fixed module in the control protocol, used to represent basic device information, such as manufacturer, data identifier (did), firmware version, etc. The service information corresponding to the basic module is used to represent device functions. The data model of the preset protocol includes a second module, including services representing the functions of the second module, and a series of properties representing device-related information of the second device. These properties may include a list of access devices, a list of device real-time download speeds, or an access device-device real-time download speed structure. The access device column represents a series of access devices that have established connections with the second module, the device real-time download speed list represents the real-time download speed of each access device, and the access device-device real-time download speed structure establishes the correspondence between each access device and its corresponding real-time download speed. The access device list, device real-time download speed list, and access device-device real-time download speed structure constitute complex data types. Preset fields (data-type-defs) can be added to uniformly manage these complex data types. Specifically, the preset fields manage the data types required for the "access device" and "device real-time download speed" attributes. Within these attributes, complex data types can be used directly in the same way as simple data types. Simple data types in attributes are represented by specific fields (format), such as "format":"bool". Complex data types are used in a similar way, but instead of simple data types, they are referenced based on preset fields. In one example, a complex data type is referenced as follows: "format":"$ref / data-type-defs / device-list".

[0059] In this embodiment of the disclosure, when the associated third device changes, the second device obtains updated device-related information and sends the updated device-related information to the cloud based on a preset protocol, so that the cloud sends the updated device-related information to the first device. The following embodiments of this disclosure describe the method for obtaining and displaying device-related information.

[0060] Figure 5 This is a flowchart illustrating a method for obtaining and displaying device-related information according to an exemplary embodiment. Figure 5 As shown, the method includes the following steps.

[0061] In step S201, the first device obtains the device-related information of the second device from the cloud and displays the device-related information.

[0062] In step S202, the first device obtains the latest updated device-related information from the cloud and displays the updated device-related information.

[0063] In this embodiment, if the second device associates with a new third device or some third devices are no longer associated with the second device, it is considered that the associated third devices have changed. In this case, the second device obtains the updated device-related information and sends the updated device-related information to the cloud based on a preset protocol, so that the cloud sends the updated device-related information to the first device. If the device-related information of the third device is updated, but the first device is still displaying the old device-related information to the user, the first device obtains the updated device-related information from the cloud and displays the updated device-related information. Through this disclosure, the second device monitors its own status in real time, obtains updated device-related information when its own status changes, and sends the updated device-related information to the first device through the cloud, so that the device-related information viewed by the target device through the first device matches the actual situation of the second device.

[0064] In this embodiment of the disclosure, the second device is associated with one or more third devices. A change in the number of third devices associated with the second device is considered a change in the number of third devices associated with the second device. The following embodiments of this disclosure further illustrate the situation where the third devices associated with the second device change and the method for obtaining updated device-related information.

[0065] In one embodiment of this disclosure, a change in the third device associated with the second device includes: the second device newly associating with a third device. The updated device-related information includes a device identifier and the association information corresponding to the newly associated third device, where the device identifier represents the newly associated third device. The device identifier and the association information corresponding to the newly associated third device are constructed into a target structure by the second device, and the target structure is added to a history list by the third device to obtain the updated device-related information. The history list includes the device-related information before the update.

[0066] In this embodiment, when a second device is associated with a new third device, it is considered that the associated third device has changed. In this case, the second device determines the device identifier and association information of the newly associated third device, constructs a target structure from these identifiers and association information, adds the target structure to the history list, updates the device association information, obtains the updated device association information, and uploads the updated device association information to the cloud. The cloud then sends the updated device-related information to the first device, allowing the user to view the updated device-related information through the first device. The history list includes the device-related information before the update; that is, the history list includes the device identifiers of the third devices already associated with the second device and their association information, and includes a structure consisting of the device identifiers of the associated third devices and their corresponding association information. Through this disclosure, the second device monitors its associated third devices in real time, obtains updated device-related information when the associated third devices change, and sends the updated device-related information to the first device via the cloud, ensuring that the device-related information viewed by the target device through the first device matches the actual situation on the second device.

[0067] It is understandable that changes to the third device associated with the second device also include situations where the second device disconnects from the associated third device. In this case, the structure corresponding to the disconnected third device can be deleted from the history list to update the device association information.

[0068] Furthermore, it can be understood that when a second device is associated with a third device, the interaction state between the third device and the second device will continuously change. In this case, the association information corresponding to the third device will change accordingly. Based on this, this disclosure can update the device association information in response to changes in the association information corresponding to the third device. That is, the second device monitors the association information of the third device it is associated with. If the association information of the third device changes, it obtains the latest association information and updates the corresponding structure based on the device identifier of the third device, thereby completing the update of the device-related information and obtaining the updated device association information. The updated device association information is uploaded to the cloud, so that the cloud sends the updated device-related information to the first device, allowing the user to view the updated device-related information through the first device.

[0069] In an exemplary embodiment of this disclosure, when the first device is a user terminal, the second device is a router, and the third device is an access device that accesses the router's wireless network,... Figure 6 This is a schematic diagram illustrating a device information access method according to an exemplary embodiment of the present disclosure, such as...Figure 6 As shown, the updating of device association information is illustrated as follows: After the access device connects to the network provided by the router, the router determines the device identifier of the access device, denoted as:

[0070] The value is set to "device_mac": "xx:xx:xx:xx", and the network download speed of the access device (related information) is determined and recorded as:

[0071] "download_speed": "xxxkb / s". Then, based on the device identifier of the access device and the network download speed, a target structure (denoted as device-download) corresponding to the access device is constructed. The construction method is as follows:

[0072] {“device_mac”:”xx:xx:xx:xx”,”download_speed”:”xxxkb / s”}. The constructed target structure corresponding to the access device is added to the history list (device-download-list), where the history list is a list of associated devices and network download speeds conforming to a preset protocol specification. The router uploads the history list with the added target structure as updated device-related information to the cloud based on the preset protocol, and the cloud transmits the updated device-related information to the user terminal. The user terminal displays the device-related information to the user through a preset terminal application. For this exemplary embodiment, it can be understood that if there are no access devices for the router, the list used by the router to store device-related information is an empty list, which can be denoted as: [].

[0073] In this embodiment of the disclosure, the process of obtaining device-related information and uploading it to the cloud is performed by the second device. The following embodiments of this disclosure describe the device information access method applied to the second device.

[0074] Figure 7 This is a flowchart illustrating a device information access method applied to a second device according to an exemplary embodiment. Figure 7 As shown, the method includes the following steps.

[0075] In step S301, the second device obtains device-related information based on the third devices associated with the second device and the association information corresponding to each third device. The association information represents the interaction state between the corresponding third device and the second device, and the device-related information represents the third devices associated with the second device and the association information corresponding to each third device.

[0076] In step S302, the second device uploads device-related information to the cloud so that the cloud sends device-related information to the second device when the first device sends a request to the cloud to obtain device-related information. The first device requests device-related information from the cloud when it receives a data access instruction from the user. The first device, the second device, and the cloud are associated with each other and interact based on a preset protocol. The preset protocol represents device-related information through lists and structures.

[0077] In this embodiment, after receiving a data access command from a user, the first device determines the second device corresponding to the data access command. The first device retrieves and displays the device-related information of the second device from the cloud. The device-related information stored in the cloud is the device information automatically uploaded by the second device. The first device, the second device, and the cloud are associated, and they interact based on a preset protocol. The device-related information is transmitted from the second device to the cloud based on the preset protocol. The preset protocol represents the device-related information through lists and structures. The device-related information represents the third devices associated with the second device and the associated information for each third device. The associated information represents the interaction state between the corresponding third device and the second device.

[0078] This disclosure provides a complex data type that can represent complex information for a preset protocol, enabling the preset protocol to support devices with complex functions.

[0079] In this embodiment of the disclosure, when the associated third device changes, the second device obtains updated device-related information and sends the updated device-related information to the cloud based on a preset protocol, so that the cloud sends the updated device-related information to the first device. The following embodiments of this disclosure describe the process of updating device-related information and uploading the updated device-related information to the cloud.

[0080] Figure 8 This is a flowchart illustrating a method for sending device-related information according to an exemplary embodiment. Figure 8 As shown, the method includes the following steps.

[0081] In step S401, in response to a change in the third device associated with the second device, the second device updates its device-related information to obtain the updated device-related information.

[0082] In step S402, the updated device-related information is sent to the cloud based on a preset protocol, so that the cloud sends the updated device-related information to the first device, and the first device obtains and displays the updated device-related information.

[0083] In this embodiment, if the second device associates with a new third device or some third devices are no longer associated with the second device, it is considered that the associated third devices have changed. In this case, the second device obtains the updated device-related information and sends the updated device-related information to the cloud based on a preset protocol, so that the cloud sends the updated device-related information to the first device. If the device-related information of the third device is updated, but the first device is still displaying the old device-related information to the user, the first device obtains the updated device-related information from the cloud and displays the updated device-related information. Through this disclosure, the second device monitors its own status and obtains updated device-related information when its own status changes, and sends the updated device-related information to the first device through the cloud, so that the device-related information viewed by the target device through the first device matches the actual situation of the second device.

[0084] In this embodiment of the disclosure, the second device is associated with one or more third devices. A change in the number of third devices associated with the second device is considered a change in the number of third devices associated with the second device. The following embodiments of this disclosure further illustrate the method for the second device to obtain updated device-related information.

[0085] Figure 9 This is a flowchart illustrating a method for obtaining updated device-related information according to an exemplary embodiment. The method includes the following steps.

[0086] In step S501, in response to the second device being newly associated with a third device, it is determined that the third device associated with the second device has changed.

[0087] In step S502, the second device determines the device identifier representing the newly associated third device and determines the association information of the newly associated third device.

[0088] In step S503, the association information and device identifier of the newly associated third device are constructed into a target structure, and the target structure is added to the history list to obtain the updated device-related information. The history list includes the device-related information before the update.

[0089] In this embodiment, when the second device is associated with a new third device, it is considered that the associated third device has changed. In this case, the second device determines the device identifier and association information of the newly associated third device, constructs a target structure from the device identifier and association information, adds the target structure to the history list, updates the device association information, obtains the updated device association information, and uploads the updated device association information to the cloud. The cloud then sends the updated device-related information to the first device, allowing the user to view the updated device-related information through the first device. The history list includes the device-related information before the update; that is, the history list includes the device identifier of the third device already associated with the second device and the association information of the associated device, and includes a structure consisting of the device identifier of the associated third device and the corresponding association information of the associated device.

[0090] Through this disclosure, the second device monitors its associated third device in real time, obtains updated device-related information when the associated third device changes, and sends the updated device-related information to the first device via the cloud, so that the device-related information viewed by the target device through the first device matches the actual situation of the second device.

[0091] In this embodiment, after receiving a data access command from a user, the first device determines the second device corresponding to the data access command. The first device retrieves and displays the device-related information of the second device from the cloud. The device-related information stored in the cloud is the device information automatically uploaded by the second device. The first device, the second device, and the cloud are associated, and they interact based on a preset protocol. The device-related information is transmitted from the second device to the cloud based on the preset protocol. The preset protocol represents the device-related information through lists and structures. The device-related information represents third devices associated with the second device and the associated information for each third device. The associated information represents the interaction state between the corresponding third device and the second device. Specifically, the list represents the third devices associated with the second device in the device-related information, and the list also represents the associated information for each third device; the structure represents the association relationship between each third device and its corresponding associated information. Furthermore, if the associated third device changes, the second device retrieves the updated device-related information and sends it to the cloud based on the preset protocol, so that the cloud sends the updated device-related information to the first device, and the first device displays the updated device-related information to the user. This disclosure specifies a complex data type capable of representing complex information for a pre-defined protocol, enabling the pre-defined protocol to support devices with complex functions. The second device monitors its own status and, upon changes in its status, obtains updated device-related information. This updated information is then sent to the first device via the cloud, ensuring that the device-related information viewed by the target device through the first device matches the actual situation on the second device.

[0092] Based on the same concept, this disclosure also provides a device information access device 100.

[0093] It is understood that the device information access device 100 provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions.

[0098] In one embodiment, when a change occurs to the associated third device, the second device updates its device-related information, obtains the updated device-related information, and sends the updated device-related information to the cloud based on a preset protocol, so that the cloud sends the updated device-related information to the first device. During the process of the first device displaying the device-related information, the processing unit 102 uses the following method to enable the first device to obtain and display the device-related information of the second device from the cloud: the first device obtains the latest updated device-related information issued by the cloud and displays the updated device-related information.

The second device constructs a target structure from the device identifier and the association information corresponding to the newly associated third device, and the target structure is added to a history list by the third device to obtain the updated device-related information. The history list includes the device-related information before the update.

[0102] The transmission unit 202 is used for the second device to upload device-related information to the cloud, so that the cloud sends device-related information to the second device when the first device sends a request to the cloud to obtain device-related information. The first device requests to obtain device-related information from the cloud when it receives a data access instruction from the user. The first device, the second device and the cloud are associated, and the first device, the second device and the cloud interact based on a preset protocol.
