Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to a dynamic updating method and device for virtual equipment composition.
Background
Under the intelligent home application scene, when a single intelligent household appliance cannot meet the requirements of a user, the cloud platform can combine and call related functions of a plurality of household appliances, and a virtual form device (namely, a virtual device) is constructed to provide required services for the user.
Specifically, international standards organization oneM2M in the field of internet of things proposes 3 device types, as shown in fig. 1, including: physical equipment: i.e. the real existing device morphology in reality. Abstract device: when a physical device accesses the oneM2M platform, the platform abstracts the device into a plurality of basic functional units, which are called abstract devices. The abstract device only has general properties, and shields the underlying network technology and physical form of the device. Virtual equipment: the oneM2M platform selects relevant devices from existing devices (including abstract devices and virtual devices), and generates virtual devices through mash-up (mash-up) to provide new services. The virtual device does not actually exist, but exists in the oneM2M platform in software.
oneM2M proposes a device modeling scheme as shown in fig. 2. The Device model is mainly composed of several operations (operations) for describing the functions provided by the Device; each operation in turn contains several parameters (parameters); in addition, the device basic information such as manufacturer, product identification and the like is also included.
oneM2M also proposes a virtual device on-demand creation method based on semantic combination technology. Taking an Air Pollution Index (API) queried by a user at home as an example, the oneM2M platform semantic engine combines partial functions (CO2 detection, VOC monitoring, etc.) of existing household appliances into a new resource, namely, an Air Pollution monitoring device, so as to meet the query requirements of the user, as shown in fig. 3, the specific steps are as follows:
step 1, the application sends a semantic query request to the semantic engine of oneM2M platform, such as the number of APIs in home.
Step 2, the semantic engine queries whether the existing device can satisfy the query, wherein the semantic engine and the Common Services Function (CSF) form a Common Services Entity (CSE).
And step 3, the CSF returns the query result, and resources which can meet the query do not exist.
And 4, determining the semantic description of the user by the semantic engine according to the user query, such as determining that the API comprises CO2 concentration and VOC concentration.
And 5, querying member resources (abstract devices) related to the semantic description by the semantic engine.
Step 6, the CSF returns a Uniform Resource Identifier (URI) of the discovered member Resource.
And 7, the semantic engine requests to create the virtual equipment and establishes association with the corresponding member resources.
Step 8, CSF returns the virtual device creation result.
And 9, storing and operating the virtual equipment by the semantic engine.
Step 10, the semantic engine inquires data from the member resource associated with the virtual device.
The CSF returns the data query result, step 11.
Step 12, the semantic engine calculates the user query result based on the acquired data, applying the service logic.
And step 13, the semantic engine returns the query result to the application end.
Because the virtual device includes functions from multiple home devices, when the state, location, and other attributes of a certain home device change, the virtual device may not continue to provide the service required by the user; the prior art only describes the creation process of the virtual device, and does not relate to the dynamic maintenance and update mechanism of the virtual device. In an actual application scenario, after the virtual device is created, a user may close a certain home device or change the function and location of the home device according to the user's own needs at any time, which may cause the virtual device to be unable to continue providing services.

The present invention will be described in further detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Method embodiment
According to an embodiment of the present invention, a method for dynamically updating a virtual device composition is provided, fig. 4 is a flowchart of the method for dynamically updating a virtual device composition according to the embodiment of the present invention, and as shown in fig. 4, the method for dynamically updating a virtual device composition according to the embodiment of the present invention includes the following steps:
step 401, creating an abstract device for a physical device accessing to a network (cloud platform) according to a preset abstract device model, wherein parameters of the abstract device model include: attribute information of the abstract device, preferably, the attribute information of the abstract device includes at least one of: device status, device location; in practical applications, the attribute information further includes device operations for describing the functions provided by the device; the device state is used to describe whether the abstract device is currently available, and the device location is used to describe the location of the abstract device.
Preferably, in the embodiment of the present invention, before creating the abstract device, a selection priority rule of the abstract device may also be created. Specifically, the selecting the priority rule specifically includes: firstly, other available abstract devices included in the physical device corresponding to the virtual device to which the abstract device belongs are selected, for example, if the virtual device vD _1 includes 3 abstract devices a, b, and c, which are respectively from the physical device A, B, C, when a is unavailable, all available abstract devices created based on A, B, C have the highest priority; secondly, selecting available abstract devices positioned in other physical devices; and finally, selecting the currently unavailable abstract device, wherein when the currently unavailable abstract device is selected, according to the shutdown time, firstly selecting the abstract device with the longest shutdown time of the corresponding physical device, and secondly selecting the abstract device with the shorter shutdown time of the corresponding physical device.
Step 402, obtaining attribute information of abstract device in new virtual device obtained by hybrid aggregation of abstract device and/or existing virtual device
Specifically, before step 402, according to a service requested by a user, the abstract device and/or the existing virtual device are mixed to create a new virtual device, and the new virtual device provides a service for the user; the abstract devices and/or existing virtual devices may be mixed together according to selection priority rules to create new virtual devices.
Step 403, when detecting that the attribute information of the abstract device in the new virtual device changes, acquiring another abstract device to replace the abstract device to provide service for the user, where the other abstract device is an abstract device that provides the same service as the abstract device. In step 403, other abstract devices may be obtained according to the priority rule to replace the abstract device to provide services for the user;
specifically, in step 403, when it is detected that the device state of the abstract device in the new virtual device changes, acquiring another abstract device to replace the abstract device to provide a service for the user, where the other abstract device is an abstract device that provides the same service as the abstract device;
when the device position of the abstract device in the new virtual device is detected to change, acquiring other abstract devices to replace the abstract device to provide services for the user, wherein the other abstract devices are the abstract devices which have the same position as the original device of the abstract device and provide the same services.
The above technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
When the household appliance equipment (namely the physical equipment) is registered to the cloud platform, the cloud platform can abstract the independent functions or services provided by the physical equipment to generate a plurality of abstract equipment; after receiving the user requirement, the cloud platform analyzes the service required by the user, inquires corresponding abstract equipment, and further finds the household appliance equipment and the specific function required to be called by the user. The technical solution of the embodiment of the present invention extends the device model shown in fig. 2, and adds a device state (Status) attribute and a device Location (Location) attribute to obtain an abstract device model absDevice shown in fig. 5.
Wherein, Status attribute: for describing whether the abstract device is currently available; the availability of the abstract device is determined according to the current on-off state of the source device (i.e. the physical device abstracting the abstract device), and the attributes of the function mode (such as mutually exclusive functions of cooling, heating, dehumidifying, etc. of the air conditioner).
Location attribute: for describing the concrete location of the abstract device in the home; the location of the abstract device is the same as the location of the source device. This attribute represents to a large extent the specific environmental attributes that the abstract device acts on, such as which room's temperature can be lowered, which room's humidity is obtained, etc.
It is assumed that the virtual device vD _1 comprises an abstract device aD _1 that can provide the service S _ 1. When the Status attribute of aD _1 changes from available to unavailable or the Location attribute changes (such as moving out of the current room), vD _1 is triggered to be dynamically updated. In the dynamic update process of vD _1, the cloud platform selects other abstract devices, which are the same as the service (S _1) provided by aD _1 and Location, including a usable device (Status) and an unusable device (Status). When a plurality of abstract devices are selected, the priority is sequentially from high to low:
1. other available abstract devices are included in the vD _1 related physical devices, and the purpose is to call as few physical devices as possible to meet the user requirements;
2. other available abstract devices not included in the vD _ 1-related physical device, in order to not start the physical device as new as possible;
3. other abstract devices not currently available, wherein the shorter the source device power-off time of the abstract device, the lower the priority selected, in order to minimize the number of home devices that the user has just turned off.
Wherein rules 2 and 3 are also applicable during virtual device creation.
The following illustrates a dynamic updating method for virtual device composition according to an embodiment of the present invention through a specific home application scenario. In this example, an air conditioner AC, an air purifier Cleaner, and an electric Heater are disposed in the main bedroom. Assuming that both the AC and the Heater have access to the network, the Heater is in the power-on state and the AC is in the power-off state. At this time, Cleaner accesses the network. The user requests "air steward" services including a room temperature conditioning (warming) function and an air purification function in the master bedroom.
The abstract devices generated by each household appliance are as follows:
AC: the heating working mode can be abstracted to an abstract device ac _ heater, and the PM2.5 purification function can be abstracted to an abstract device ac _ pm2.5 cleaner; cleaner: abstractable as an abstract device cl _ cleaner; a Heater: abstractable as an abstract device ht _ header.
Fig. 6 is a flowchart of detailed processing of a virtual device composition dynamic update method according to an embodiment of the present invention, and as shown in fig. 6, the method specifically includes the following processing:
step 0: an abstract device model is predefined, and a priority rule of abstract devices selected in the dynamic updating process of the virtual devices is defined.
Step 1: the purifier Cleaner accesses the network and sends an access request to the cloud platform.
Step 2: after receiving an access request of Cleaner, the cloud platform creates abstract equipment cl _ Cleaner based on the abstract equipment model; where Status is True (currently available) and Location is the master bedroom.
And step 3: the user sends a service request to the cloud platform through the APP and hopes to obtain 'air manager' service in the master bedroom.
And 4, step 4: the cloud platform queries abstract equipment capable of providing room temperature improvement and air purification service in the main bedroom according to user requirements, and acquires an ht _ heater and an ac _ heater with the room temperature improvement function and a cl _ cleaner and an ac _ pm2.5cleaner with the air purification function respectively; and according to a preference rule, selecting currently available ht _ heater and cl _ cleaner, creating a virtual device AirManager, and providing services for the user.
And 5: in the process of the AirManager providing the service, the user moves the Heater from the master bedroom to the secondary bedroom.
Step 6: the cloud platform finds that the position of the Heater changes (through indoor positioning or active reporting of the Heater), determines that the position of the ht _ Heater changes through the association relation, cannot continuously provide the service for improving the temperature of the master bedroom, and triggers the air manager to update.
And 7: and the cloud platform queries abstract equipment which can replace the ht _ heater, acquires the AC _ heater which is in the unavailable state at present, and acquires the corresponding source household appliance AC.
And 8: the cloud platform sends a power-on instruction to the AC and sets the functional mode of the AC to 'heating' to ensure that the Status of the AC _ heater becomes True.
And step 9: in the process that the AirManager provides the service, the user sends a shutdown instruction to Cleaner through APP; and after receiving the instruction, Cleaner executes the operation and reports the new state to the cloud platform.
Step 10: after receiving the Cleaner report message, the cloud platform determines that the abstract device cl _ Cleaner becomes unavailable through the incidence relation and cannot continuously provide the air purification service of the master bedroom, and triggers the AirManager to update.
Step 11: and querying an abstract device capable of replacing the ht _ heater by the cloud platform, acquiring AC _ pm2.5cleaner in an unavailable state at present, and acquiring a corresponding source household appliance AC.
Step 12: the cloud platform sends an instruction to the AC, and the PM2.5 purification function is started.
In summary, in the technical solution of the embodiment of the present invention, by adding the attribute field in the abstract device description mode, the change of the functional availability and the position of the home appliance device is used as a basis for triggering the update of the virtual device, and a priority selection rule of the replacement device is predefined in the update process of the virtual device; and when the virtual equipment updating process is triggered, the cloud platform selects new household electrical equipment according to a predefined rule to replace the existing unavailable equipment and continuously provide services for the user.
