[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 numerals 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. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0043] Figure 1 This is a schematic diagram of the architecture of a communication system according to embodiments of this disclosure. Figure 1 As shown, the communication system 100 includes a PLC gateway 110 and a sub-device 120. The PLC gateway 110 includes a first master control device 111 and a CCO 112, and the sub-device 120 includes a second master control device 121 and a STA 122.

[0044] The PLC gateway 110 can communicate with the terminal device 130 via the cloud or directly, for example, based on the 3GPP protocol.

[0045] It is worth noting that in some embodiments, the PLC gateway 110 can also communicate with sub-devices other than sub-device 120. These sub-devices and sub-device 120 can form a PLC network, and the terminal device 130 can schedule one or more devices in the PLC network.

[0046] The following describes the application scenarios of embodiments of this disclosure. For example, the sub-device can be a device in a user's home, such as a light or curtain. The user can then operate the sub-device through a terminal device and a PLC gateway. The user can connect the sub-device to the cloud for communication through the terminal device and the PLC gateway. The PLC gateway and the sub-device communicate using PLC communication. The main control device can be Linux, Android, MCU (Microcontroller Unit), etc., and the main control device communicates with the module using serial communication or other methods.

[0047] The data model used in the communication process of a PLC device in related technologies is as follows: The device is used to represent a specific physical device of a PLC, such as a switch or a light.

[0048] A profile is used to represent the data definition capabilities and formats for interaction between a device and other subsystems, and to describe the capabilities and status data of the device. A service is a collection of data and related behaviors used to achieve specific functions and features.

[0049] Characteristic is used to represent specific data or functional behavior.

[0050] The name is used to represent the characteristic.

[0051] The `type` property is used to represent the data type of a characteristic, such as integer, string, container, etc.

[0052] The method is used to represent the characteristics, such as read-only, write-only, readable or writable, and readable and writable.

[0053] The format is used to represent the format of a characteristic.

[0054] The above model allows for the definition of device information, or profile, for PLC devices. The applicant's research has found that in real-world scenarios, the operational data sent by the control device to the controlled device is used to instruct the controlled device to perform corresponding operations, the results of which are perceptible to the user. Based on this, the present disclosure provides the following embodiments.

[0055] Figure 2 The diagram shown is an interactive schematic of a communication method provided according to an embodiment of the present disclosure. Figure 2 As shown, this method is applied to a control device, and the method may include: S201: Send first data to the controlled device, wherein the first data includes a behavior identifier, and the first message is used to instruct the controlled device to perform the behavior indicated by the behavior identifier, wherein the controlled device is a power line carrier communication PLC device; In this case, the behavior indicated by the behavior identifier does not require the controlled device to return a response message.

[0056] For example, the control device can be Figure 1 The Central Coordinator (CCO) shown in the diagram allows user terminal devices to establish a communication connection with the PLC gateway via the cloud. Users can then send data to the STA (Station) through the CCO in the cloud and PLC gateway, enabling interaction with the STA. The control device can be... Figure 1 The terminal node STA shown can be a switch, and the controlled device is... Figure 1 The terminal node STA shown can be a lamp.

[0057] In some embodiments, the behavior of the controlled device can be pre-analyzed to identify behaviors that do not require a response message, and behavior identifiers can be pre-configured for these behaviors. For example, regarding the switching behavior of a light, when the light changes from on to off or from off to on, the user can perceive the result of the behavior through the light's feedback. Similarly, regarding the volume adjustment behavior of a playback device, the user can perceive the result of the behavior based on changes in the sound played by the playback device. For such behaviors, after the controlled device performs the behavior, the user can directly perceive the result of the behavior based on the performance of the controlled device; in this scenario, the controlled device does not need to return a response message indicating the result of the behavior to the control device.

[0058] In this embodiment, the control device can directly send first data to the controlled device, which includes a behavior identifier, so that the controlled device can perform the corresponding behavior when it receives the behavior identifier, without having to return a response message.

[0059] Among them, behavior identifiers can be used to indicate data operations transmitted between the control device and the controlled device, and to invoke behaviors on the controlled device. As an example, it can use an unsigned integer to identify its type, and can be used as a separate data interaction type.

[0060] Therefore, through the above technical solution, during the interaction between the control device and the controlled device, the control of the controlled device can be achieved through behavior identifiers, so that the control device does not need to return a response message after executing the behavior. This can achieve control of the controlled device while saving the communication resources occupied by the response message.

[0061] In some embodiments, the control device stores device information of the controlled device, the device information including at least one service identifier of the controlled device, and each service identifier includes at least one behavior identifier.

[0062] For example, when a control device sends a toggle command to a controlled device, the path for transmitting the behavior identifier can be represented as siid / aiid. siid represents the service ID in the controlled device, and aiid represents the action ID. When the control device sends siid / aiid data to the controlled device, it will invoke the action indicated by the aiid on the controlled device, i.e., the toggle action. If the controlled device receives this action identifier when it is in the on state, the device state changes to off; otherwise, the device state is on.

[0063] In some embodiments, the method may further include: Based on the event identifier, event information occurring in the controlled device is obtained, wherein the service identifier also includes at least one event identifier, and different event identifiers indicate different event types.

[0064] Event identifiers can be used to define records of past events, such as device logs, to provide the time and content of the event. Event information is read-only. Accordingly, the event information indicated by the event identifier can include a timestamp of the event and the specific content of the event (e.g., specific data). For example, event types can include device restart, device on, and device off, etc. These different types can be represented by different identifiers, allowing the type of event to be determined based on the event identifier. For instance, a device restart event has the event type "device restart," and the event information includes the restart timestamp and the reason for the restart, such as power failure restart, hardware reset restart, or software error restart. As another example, in a door lock scenario, an unlocking event triggered when a user unlocks the door can be represented by a device on event identifier, with the unlock timestamp recorded in the event information. A locking event triggered when a user locks the door can be represented by a device off event identifier, with the locking timestamp recorded in the event information.

[0065] Therefore, through the above technical solution, events occurring on the device can be recorded and represented by event identifiers, so that the control device can easily obtain event information occurring in the controlled device, thereby enabling rapid identification of data in the controlled device.

[0066] In some embodiments, obtaining event information occurring in the controlled device based on event identifiers may include: The controlled device receives second data sent by the controlled device, wherein the second data contains the event identifier and the event information corresponding to the event identifier, and the second data is sent by the controlled device when the event indicated by the event identifier occurs.

[0067] like Figure 3 The diagram shown is an interactive schematic of a communication method provided according to an embodiment of the present disclosure.

[0068] S301: Receive the second data sent by the controlled device.

[0069] As an example, when an event indicated by an event identifier occurs in the controlled device, the controlled device can generate event information for that event and proactively report the event information to the control device. For instance, when a restart event occurs on the controlled device, the controlled device can record the restart timestamp and the reason for the restart to generate event information, and then send the event information to the control device. As an example, the path of the event identifier in the second data can be represented as siid / eiid, where eiid represents the event identifier, so that when the control device receives the second data, it can determine which service and which event identifier the event information corresponds to based on siid / eiid.

[0070] Therefore, when a corresponding event occurs, the controlled device can actively send event information to the control device, so as to quickly detect the event occurring in the controlled device and provide data support for the safe and stable operation of the controlled device.

[0071] In some embodiments, the step of obtaining event information occurring in the controlled device based on event identifiers, such as... Figure 4 As shown, it may include: S401: Send third data to the controlled device, wherein the third data includes the event identifier. Specifically, when the control device needs to obtain an event occurring in the controlled device, for example, if the user determines the event identifier corresponding to the type of event they want to view based on their needs, such as wanting to view a door lock unlocking event, and the event identifier corresponding to the unlocking event is XXX1, then the control device can send third data, whose path can be represented as siid / eiid (e.g., siid / XXX1).

[0072] S402: Receive fourth data sent by the controlled device, wherein the fourth data includes the event identifier and the event information corresponding to the event identifier.

[0073] When the controlled device receives the third data, it can retrieve the event information corresponding to that event identifier based on the callback function. Specifically, it can retrieve the event information for event identifier XXX1 from the controlled device. In this scenario, the event information can include multiple events, such as the unlocking events of a door lock at different times. After obtaining the event information, it can send the event information and the event identifier together to the control device. Upon receiving the fourth data, the control device can then determine the received event information and which service and event identifier it belongs to.

[0074] Therefore, the above technical solution can also support the control device to query and obtain event information in the controlled device, and the event information can be represented based on the event identifier, which also facilitates the rapid identification and analysis of time information.

[0075] In some embodiments, within the data model structure used by the device, services may include behaviors and events. Different behavior identifiers identify individual behaviors, and different event identifiers identify various event types. Services may also include attributes; other information within the service can be identified through attribute (characteristic) identifiers or defined based on other defined identifiers. Different identifiers indicate different data or functions of the device.

[0076] As an example, when the control device is a Control Operator (CCO), the device information of the controlled device can be retrieved from the cloud via a communication connection between the CCO and the cloud. As another example, when the control device is a Switching Array (STA), this disclosure also provides the following embodiments for obtaining the device information of the controlled device.

[0077] In some embodiments, the method further includes: Based on the resource service identifier, obtain the device information of the controlled device; The resource service identifier indicates a service used to record device information, which includes at least one of device type, device name, and a list of device service identifiers, and the list of service identifiers includes various service identifiers in the device.

[0078] In this embodiment, a resource service can be predefined, associated with a resource service identifier. This resource service is used to record device information; that is, the device information can be stored under the service indicated by the resource service identifier. Thus, during device interaction, devices can obtain the resource information of the controlled device through this resource service identifier. Typically, the attribute identifier ciid, event identifier eiid, and behavior identifier aiid included under the service are fixed. Therefore, when obtaining the device's service identifier siid, the ciid, eiid, and aiid under the service indicated by the service identifier can be further clarified without needing to obtain this information separately.

[0079] In some embodiments, the step of obtaining the device information of the controlled device based on the resource service identifier, such as... Figure 5 As shown, it may include: S501: Send fifth data to the controlled device, wherein the fifth data includes the resource service identifier; S502: Receive device information sent by the controlled device.

[0080] As an example, a resource service identifier r_service id is defined as XXXX1, which includes a characteristic id of XX1. This characteristic id represents the specific data within the service indicated by the resource service identifier, i.e., the device information of the device. The controlling device can then send XXXX1 / XX1 to the controlled device to obtain the device information. This allows for the rapid acquisition of device information, enabling the display of corresponding plugins. Users can then use these plugins to understand the services offered by the device and to perform operations on the controlled device as needed.

[0081] In some embodiments, the controlled device includes multiple sub-devices and a virtual master device.

[0082] Taking a switch as an example, a switch can be a single-button switch or a multi-button switch. In a multi-button switch, each button can be considered a sub-device, and the virtual master device is used to represent the device in the multi-button switch used to configure each sub-device.

[0083] As an example, a schematic diagram of the data model of the device provided based on embodiments of this disclosure is shown below. Figure 6 As shown, `module` represents a sub-device, meaning a module added on top of the service. `Event` represents an event, which may contain fields describing the event, such as a timestamp and event data. These fields can be pre-configured based on actual usage requirements, and this disclosure does not impose any limitations on them. `Action` represents a behavior, which may contain fields describing the behavior, such as name and type. These fields can also be pre-configured based on actual usage requirements, and this disclosure does not impose any limitations on them.

[0084] Accordingly, obtaining the device information of the controlled device based on the resource service identifier may include, for example: Figure 7 As shown: S701: Send sixth data to the controlled device, the sixth data including the resource service identifier and the identifier of the virtual host device.

[0085] S702: Receive device information of the virtual master device sent by the controlled device, wherein the device information further includes the sub-device identifiers of the plurality of sub-devices.

[0086] For example, the identifier of the virtual master device can be module 0. The device information of the virtual master device can be stored in the service indicated by the resource service identifier in the virtual master device. The device information of the virtual master device can include device type, device name, service identifier list and various sub-device identifiers. As an example, multiple sub-device identifiers can be represented by a list.

[0087] When configuring the device information of the controlled device, since the controlled device contains multiple sub-devices, and specific services are executed through these sub-devices, the device type in the virtual master device can be the type of the sub-device that serves as the primary device among the multiple sub-devices. The service identifier list of the virtual master device can be empty. Upon receiving the sixth data, the controlled device can determine, based on the sixth data, the device information of the virtual master device to be obtained. It can then retrieve the device information recorded in the service indicated by the resource service identifier in the virtual master device and send it to the control device.

[0088] S703: Send seventh data to the controlled device, the seventh data including a first sub-device identifier and the resource service identifier, wherein the first sub-device identifier is any one of the plurality of sub-device identifiers.

[0089] S704: Receive device information of a sub-device indicated by the first sub-device identifier sent by the controlled device. The device information of the controlled device includes the device information of the plurality of sub-devices and the virtual sub-device. The same service in different sub-devices is indicated by the same service identifier.

[0090] In this embodiment, the controlled device is distinguished by multiple sub-devices, so the same service under different sub-devices can be indicated by the same service identifier. For example, if the controlled device is a switch type containing four buttons, the device is physically a switch device. Regarding switch services, related technologies typically use different service identifiers to represent the switch services corresponding to different buttons. Based on the example of this disclosure, each button is a sub-device, represented by a sub-device identifier. Therefore, the same service identifier can be used to represent the switch service in each sub-device, eliminating the need to define multiple service identifiers for the same service, thereby improving the flexibility of device information configuration.

[0091] After receiving the virtual master device information from the controlled device, the control device can obtain the sub-device identifiers of each sub-device contained within the controlled device, and then acquire the device information of each sub-device. Within the controlled device, each sub-device stores the service indicated by the resource service identifier, including the device type, device name, and a list of service identifiers contained within that sub-device. The control device can then determine the functions and data available to the controlled device based on the acquired device information, thereby enabling control over the controlled device.

[0092] In some embodiments, when sending the first data to a controlled device that includes multiple sub-devices, the first data may also include the corresponding sub-device identifier, such as path, which may be represented as miid / siid / aiid, where miid is used to represent the sub-device identifier. By transmitting the above data, the sub-device of miid in the controlled device can be instructed to perform the behavior of aiid in the siid service.

[0093] In some embodiments, when transmitting data corresponding to an event identifier to a controlled device that includes multiple sub-devices, the path can be represented as miid / siid / eiid. In this case, by transmitting the above data, it can be indicated that the event information of the eiid in the siid service of the sub-device of the miid in the controlled device can be obtained.

[0094] This disclosure also provides a communication method applied to a controlled device, which may include: The controlled device receives first data sent by the control device, wherein the first data includes a behavior identifier, and the first data is used to instruct the controlled device to perform the behavior indicated by the behavior identifier; The behavior indicated by the behavior identifier is executed, wherein the controlled device is a power line carrier communication PLC device, and the behavior indicated by the behavior identifier does not require the controlled device to return a response message.

[0095] For example, a callback function corresponding to a behavior identifier can be pre-configured in the controlled device. This callback function is used to call the method of the behavior indicated by the behavior identifier, so that the controlled device executes the behavior. After the controlled device executes the behavior indicated by the behavior identifier, it does not need to return a response message to the control device. The implementation can be designed by different device manufacturers, and this disclosure does not limit it.

[0096] Therefore, through the above technical solution, during the interaction between the control device and the controlled device, the control of the controlled device can be achieved through behavior identifiers, so that the control device does not need to return a response message after executing the behavior. This can achieve control of the controlled device while saving the communication resources occupied by the response message.

[0097] In some embodiments, the controlled device stores device information, which includes at least one service identifier of the controlled device, and each service identifier includes at least one behavior identifier. The controlled device also includes implementations of the services indicated by each service identifier and implementations of the behaviors indicated by the behavior identifiers, so as to perform corresponding operations based on the identifiers contained in the received data.

[0098] In some embodiments, the method further includes: Based on the event identifier, event information occurring in the controlled device is sent to the control device. The service identifier further includes at least one event identifier, with different event identifiers indicating different event types.
