Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

In the IoT system, resources can be used to define the function of the device. For example, in the Open Connectivity Foundation (OCF) system, resources are the logical functional entities of the device, which are exposed by the server to the client for access and operation, and the client can perform resource operations (CRUDN) and the server. Interactive.

OCF is a technical specification of the IoT system, which provides a resource-oriented architecture, and all functional entities are abstracted and described as resources. Under this architecture, OCF provides a communication and interoperability framework to adapt to various IoT applications (such as smart homes, automobiles, wearable devices, etc.), shielding manufacturers, operating systems, hardware, communication networks, etc. Differences; OCF provides a unified model to describe the environment, equipment, etc., in order to achieve the flow of information and semantic interoperability. In addition, OCF also provides protocols and mechanisms related to resource discovery, identification, and security.

The core framework of OCF includes three main aspects: resource model, operation, and abstraction.

The resource model is the foundation of the OCF architecture. It provides an abstract means for logically modeling and achieving interoperability between IoT applications. OCF defines five operations: create, retrieve, update, delete, and notify. These five operations are referred to as CRUDN for short. Based on these operations, IoT devices do not need to pay attention to the underlying protocols and The realization method can realize the corresponding function. The abstraction layer is used to map resources and operations to specific physical entities.

Each resource in the OCF can have its own uniform resource identifier (URI), some resources can have a predefined URI, and IoT devices can obtain resources by accessing the URI.

Each resource in the OCF can also contain attributes, which are used to describe related information about the resource.

Attributes exist in the form of key-value pairs (<key:value>) and can contain the following:

Property title: the display name of the property;

Property name: the identifying name of the property, the key in <key: value>;

Value type: The type of the attribute value, which can be a simple data type or a complex data type.

Value rules: constraint conditions for attribute values, for example, the maximum value, minimum value, or the range of enumerated values;

Unit: The unit of the attribute value, such as °C;

Mandatory: Indicate whether the attribute is mandatory in a certain resource type;

Access mode: The access mode of the attribute value, which can be readable (R), writable (W), or readable and writable (R, W);

Description: The readable description of the attribute.

OCF also defines resource type (resource type, rt), which is used to describe a specific application type of a type of resource. A resource can have multiple resource type definitions, that is, the "rt" attribute can have multiple attribute values, for example, "rt":["oic.wk.d","oic.d.light"].

Resource types can include the following:

Pre-defined URI (pre-defined URI): optional content, OCF is a predefined fixed resource URI for a specific resource, for example, /oic/res;

Resource type title: optional content, the display name of the resource type;

Resource type ID (resource type ID): the identifier of the resource type, that is, the value of the "rt" attribute;

Interfaces: A list of interfaces supported by this type of resource;

Description: The readable description information of the resource type, for example, "oic.r.humidity" is used to describe the environmental humidity;

Mandatory: Indicate whether the resource type is mandatory in the OCF system;

Properties: Properties related to the resource type.

Resource type is equivalent to "class"; resource is equivalent to an instance of "class", that is, "object"; attribute is equivalent to a member of "class" when defined, but is actually a member of "object" when in use. Attributes can contain multiple parameters, for example, resource type name, resource type identification, identification of whether user input is supported, identification of whether user output is supported, user input data, and user output data are all attributes (ie, resource attributes), and also For the members of the above "class", the specific values of these parameters are attribute values, which will be used when the above "object" is used. Among them, the URI and interface will be used in the communication process.

Next, the IoT system applicable to this application is introduced. As shown in Figure 1, the subscription device and the target device can be devices in the home IoT, such as mobile phones, tablets, routers, wearable devices, air conditioners, lights, water meters, etc., or smart security, air monitoring, and air monitoring. Smart devices in the field. These devices can all work in the IoT environment, that is, they can perform IoT communication.

Step 1. The subscribing device sends a subscription request to the target device. The message type of the subscription request may be Retrieve, and the subscription request may include the following parameters:

Message originator (from, Fr): the device ID of the subscribed device;

Message recipient (To): the identifier of the resource subscribed by the subscribing device;

Message identifier (request identifier, Ri): request identifier, used to complete the binding of request and response;

Operation type (operation, Op): operation type, generally one of CURDN;

Subscription identifier (observe, Obs).

Step 2: After receiving the subscription request, the target device authenticates the subscription request, establishes a monitoring mechanism, and replies a response message to the subscribing device. The response message is used to notify the subscribing device that the target device has received the subscription request and started to monitor the change of the target resource.

Step 3: After the target device detects that the target resource requested by the subscribing device has changed, it will send a notification message to the subscribing device. The Ri of the above three messages are the same.

If the subscribing device needs to unsubscribe content, it can send the subscription request in step 1 again, and set the Obs parameter to unsubscribe.

If the subscribing device needs to subscribe to other content, you can modify the Query part in the To parameter. For example, what is the Query part? if="special Interface". Subscriptions with different if parameters can be considered as different subscriptions.

Currently, some IoT devices do not have user input functions and/or user output functions due to factors such as cost or application environment. That is, these IoT devices cannot directly receive user input information, nor can they directly display output information to users, resulting in users It is inconvenient to use. The method for information interaction with users provided by this application will be introduced below.

As shown in FIG. 2, the method 200 includes:

S210, subscribing to human-computer interaction resources that comply with the OCF protocol.

The resource types of human-computer interaction resources that comply with the OCF protocol are shown in Table 1.

Table 1

The attributes of human-computer interaction resources are shown in Table 2.

Table 2

In Table 2, R means readable and W means writable.

The subscription device can read the SI in the attribute to determine whether the human-computer interaction resource supports input. For example, when the value of SI is true, it means that the human-computer interaction resource supports user input; when the value of SI is false, it means the human-computer interaction resource User input is not supported. Human-computer interaction resources that support user input are, for example, a keyboard, a mouse, a touchpad, a camera, and a pickup device.

The subscription device can also read the SO in the attribute to determine whether the human-computer interaction resource supports output. For example, when the value of SO is true, it means that the human-computer interaction resource supports user output; when the value of SO is false, it means human-computer interaction. The resource does not support user output. Human-computer interaction resources that support user output are, for example, display screens, printers, voice playback devices, projectors, and so on.

Optionally, after the subscription device discovers the human-computer interaction resource, it can first determine whether the human-computer interaction resource supports user input and/or user output, and when the human-computer interaction resource supports user input and/or user output, subscribe to the human-computer interaction resource. Interactive resources, so as not to subscribe to resources that do not support user interaction.

Below, two examples of human-computer interaction resources are given.

Example one.

The entity corresponding to the aforementioned human-computer interaction resource is a keyboard. "/My/resource/keyboard" is the URI of the human-computer interaction resource; ""rt":["oic.r.human.io"]" indicates that the resource is a human-computer interaction resource; ""SI":true" indicates a human-computer interaction resource Interactive resources support user input; ""In": "xxxxxx"" means user input content; ""SO": false" means human-computer interactive resources do not support user output.

Example two.

The entity corresponding to the aforementioned human-computer interaction resource is a display screen. "/My/resource/display" is the URI of the human-computer interaction resource; ""rt":["oic.r.human.io"]" indicates that the resource is a human-computer interaction resource; ""SI":false" indicates a human-computer interaction resource The interactive resource does not support user input; ""SO":true" indicates that the human-computer interaction resource supports user output; ""Out":"xxxxxx"" indicates the content output to the user.

The above two examples are situations where the human-computer interaction resource supports user input or user output. The human-computer interaction resource provided in this application can also support both user input and user output, for example, a tablet computer.

When the human-computer interaction resource includes a user input resource, the resource type of the human-computer interaction resource may include a type identifier for identifying the user input resource. When the human-computer interaction resource includes a user output resource, the resource type of the human-computer interaction resource may include a type identifier for identifying the user output resource. as shown in Table 3.

table 3

In Table 3, oic.r.human.in indicates that human-computer interaction resources include user input resources, that is, human-computer interaction resources support user input; oic.r.human.out indicates that human-computer interaction resources include user output resources, that is, Human-computer interaction resources support user output. In this way, when the subscription device searches for a resource, it can directly determine whether the human-computer interaction resource supports user input and user output according to the resource type ID, without further reading the attribute value to determine the type of human-computer interaction resource, thereby improving the efficiency of resource subscription .

Human-computer interaction resources may include one type of resource, for example, only user input resources or user output resources; human-computer interaction resources may also include multiple resources, for example, user input resources and output resources.

When the human-computer interaction resources include user input resources, the attributes of the user input resources are shown in Table 4.

Table 4

When the human-computer interaction resources include user output resources, the attributes of the user output resources are shown in Table 5.

table 5

After the subscribing device subscribes to the human-computer interaction resources, you can perform the following steps.

S220: Perform information interaction with the user through the human-computer interaction resource.

Fig. 3 shows a schematic flow chart of another method for information interaction with a user provided by the present application.

In Figure 3, the subscription device, device A, and device B are all IoT devices, device A has user input resources, and device B has user output resources. The subscription device can scan the resources in the local area network where it is located, and if it finds a human-computer interaction resource, it can query whether the human-computer interaction resource supports user input and/or user output. For example, if the subscribing device determines that the human-computer interaction resource of device A supports user input, it subscribes to the human-computer interaction resource of device A; the subscribing device determines that the human-computer interaction resource of device B supports user output, then it subscribes to the human-computer interaction resource of device B. The dotted arrow in the resource subscription process indicates an optional response message.

When the mobile phone instructs the subscribing device to perform the device authentication process, the subscribing device can generate a personal identification number (PIN), and use the human-computer interaction resource of the device B to display the PIN. Optionally, after displaying the PIN, the device B may notify the subscribing device that the output has changed, and the subscribing device may also notify the mobile phone that the PIN has been displayed.

After the user inputs the PIN on the device A, the device A notifies the subscribing device of the PIN, that is, the subscribing device obtains the PIN input by the user through the input resource of the device A.

Subsequently, the subscription device verifies the PIN entered by the user, thereby completing the steps of information interaction with the user through human-computer interaction resources.

It should be noted that the subscription device may be a device without user interaction function, or a device with user interaction function. When the subscription device has no user interaction function, the method described above can realize the user interaction function without increasing the cost or changing the application environment; when the subscription device has the user interaction function, if the human-computer interaction resource has more With good input and output performance, the subscription device can implement better user interaction functions through the method described above without increasing the cost or changing the application environment.

Whether a certain function is executed by hardware or computer software-driven hardware depends on the specific application and design constraint conditions of the technical solution. Professionals and technicians can use different methods for each specific application to implement the described functions, but such implementation should not be considered beyond the scope of this application.
