The inextensible drawbacks of the management system described above are particularly apparent: (1) After the system integration is finished, household appliances which are not incorporated into the system in advance cannot be accessed and managed. Adding a communication protocol between the household appliance and the cloud server, between the cloud server and the mobile phone and between the cloud server and the computer is needed when the household appliance is newly added, and the communication protocols are agreed in advance; (2) The built-in household appliances cannot be added with new functions, and as the communication protocols of the household appliances and the household fixed terminal as well as the communication protocols of the fixed terminal and the cloud server are pre-agreed, the communication protocol for a certain appliance is also fixed and unique, so that the new functions of the existing household appliances in the system cannot be added.

In practice, the remote home appliance management system is often only connected to a part of home appliances, and a new home appliance may be required to be added to the home appliance management system in the later stage, or a new function of an existing home appliance may be added. Therefore, it is necessary to consider the expansibility thereof in the home appliance management system so that a new home appliance can be easily accessed in an existing system or a new function of an existing home appliance can be added.

Detailed Description

Some embodiments of the invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.

In the description of the present invention, a "module," "processor" may include hardware, software, or a combination of both. A module may comprise hardware circuitry, various suitable sensors, communication ports, memory, or software components, such as program code, or a combination of software and hardware. The processor may be a central processor, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and/or signal processing functions. The processor may be implemented in software, hardware, or a combination of both. Non-transitory computer readable storage media include any suitable medium that can store program code, such as magnetic disks, hard disks, optical disks, flash memory, read-only memory, random access memory, and the like.

The following provides an example of the various concepts and descriptions that may be used in the present invention to define and explain the implementation of the invention more clearly.

(1) One embodiment is defined with respect to a device.

A device refers to an entity that performs a particular function. The household appliance remote management system comprises a plurality of household appliance devices, which are abbreviated as household appliances, and the functions of each device are different. The physical entity of a device is referred to as a "physical device". In order to access the functions of the devices, the invention abstracts the functions of a physical device into a data set, which is called an abstract device, and the control of the devices and the monitoring of the running states can be completed by accessing the abstract device. Under the framework of the intelligent home network, other parts for realizing remote management of the home appliances, such as a server, may have copies of abstract devices, which are called "device copies", and corresponding abstract devices located in physical devices are also called "device original values". The relationship between them is shown in an example in fig. 2. In this example, the physical device side has: abstracting information of devices, including but not limited to various functions (such as basic interface, interface 1, interface 2, … … interface n); unified transmission protocol; a physical communication interface; a physical implementation execution section of a physical device function; etc. Correspondingly, the abstract equipment information of the physical equipment has a corresponding 'equipment original value', namely the physical equipment can be remotely identified, managed and controlled to execute corresponding physical functions on the server side by the original value; i.e. the abstract device information placed on the server side is the device copy.

Further, in order to increase flexibility of device definition and facilitate abstracting device functions, the concept of "interfaces" is introduced into an abstract device (such as interface 1, interface 2, etc. in the above example), each interface represents a specific function, and a device has a certain function by implementing a certain interface. The same interface may be implemented in different devices, thus allowing different devices to have the same functional part. Three special interfaces, namely a basic interface, a server direct connection port and a container interface, are predefined, and all devices need to realize the basic interface; the server direct connection port enables the equipment to have the capability of directly establishing a link with the server and communicating, and the equipment for realizing the server direct connection port is called as 'server direct connection equipment'; having a container interface indicates that a sub-device may exist under the device, and the device implementing this container interface is referred to as a container device. As shown in fig. 3, the relationship of the device to the interface in this embodiment of the invention is illustrated. Three types of predefined interfaces have a basic interface and a server direct connection port in a device capable of implementing a server direct connection with a server, while "interface xx" may be a "container interface" representing that there is a sub-device A, B, C below the device that is directly connected with the server, and so on.

In addition, in one embodiment, an interface (illustrated as "interface xx") is allowed to appear only once within the same abstract device, so that for a device having multiple identical functional units, it is necessary to abstract the functional units within an interface, rather than abstract a single functional unit into an interface and then implement the interface multiple times.

Further, an interface contains a series of attribute items, and the set of attribute items describes the function of an interface in detail, and the attribute items are basic units for data access. When defining an interface, detailed definition and explanation of the attribute contained in the interface are needed. Fig. 4 schematically illustrates an example of a multiple switch function interface: the information contained in the multi-way switch interface may include interface version, number of switches, switch status, control instructions, etc.

(2) In one embodiment, device operation definition

The functions of the physical devices are abstracted into abstract devices, and the abstract devices exist in the physical devices of different entities participating in the operation, so that the operation on each physical device can be regarded as the operation on the abstract device. In this example, operations between abstract devices are limited to operations between a corresponding abstract device within a physical device and the other abstract device of the device, i.e., to operations between device originals and device replicas, and operations between multiple device replicas of a device are not allowed. Fig. 5 is a schematic illustration of the operation of the device: the operation on the device is equivalent to the operation between the device copy in the server and the device original value of the physical device, and finally is reduced to the operation between the attribute copy and the attribute original value, wherein only the operation between the device copy and the device original value is allowed, but the operation between the device copy and the device copy is not allowed.

More specifically, the function of a device may be abstracted into an abstract device, the abstract device is defined by an interface, and the concrete content of an interface is finally embodied by an attribute, so that the operation about the device can be ultimately summarized into the operation on the attribute. The invention refers to the attribute in the original value of the equipment as the original value of the attribute, and the attribute in the copy of the equipment is called as the copy of the attribute, so that the operation on the equipment can be finally summarized as the data exchange between the original value of the attribute and the copy of the attribute.

Still further, regarding the operation of the attribute, the related operation is described from the viewpoint of the apparatus in the present embodiment. The operation initiator or destination other than the device itself is referred to as the "remote end", the entity in the process of operation that assists in completing the communication between the device and the remote end is referred to as the "intermediary", and according to the actual situation, there may be, or may not be, multiple intermediaries involved in the data exchange process. As shown in fig. 6, the remote control is implemented by using remote control application software (e.g. smart home) APP on a user terminal device (e.g. a mobile phone, tablet, computer, etc. networked via external internet of things, internet, etc. or a terminal with short-range transmission of bluetooth, infrared, NFC, etc.), directly controlling a sub-device (without intermediate control), or intermediately controlling via a host, a server, etc. through a network.

Wherein the data transmission from the device to the remote end is called uploading and the data transmission from the remote end to the device is called downloading. The operation actively initiated by the device is active and the operation actively initiated by the remote is passive. Thus, four basic operations of the attribute, namely active upload AU, active download AD, passive upload PU and passive download PD, can be defined, and the functions of one device are completed through the four basic operations of the attribute. These four basic operations of the attribute are shown in fig. 7: the AU is actively uploaded, an operation is initiated from the attribute original value to the attribute copy, the data transmission direction is from the attribute original value side to the attribute copy, and the attribute copy is an operation initiated in response to the attribute original value; the passive uploading PU initiates an operation from one side of the attribute copy to one side of the attribute original value, the attribute original value responds to the operation and transmits data to the attribute copy; actively downloading the AD, initiating an operation on one side of the original value of the attribute, responding to the operation by the attribute copy, and transmitting the data from one side of the attribute copy to the original value of the attribute in the data transmission direction; and passively downloading the PD, initiating operation by the attribute copy side, responding operation by the attribute original value side, and transmitting data to the attribute original value by the attribute copy to receive the data.

Four basic operational summaries for attributes are described by way of example as follows: the active uploading is an operation initiated by the original value of the attribute to attempt to modify the copy, and the device can notify a remote end of some events, such as the change of the state of the device, the condition of the state of the device being met, and the like, by using the operation; active download is an operation initiated by an attribute original value to attempt to acquire a copy, and the device can acquire some external information by using the operation; passive uploading is an operation initiated by a copy to attempt to acquire an original value, and a remote end can acquire the working state of equipment by using the operation; passive download is an operation initiated by the copy that attempts to modify the original value with which the remote end can control the device operation. One attribute may support only one or a few of the four basic operations as required.

The above descriptions are all based on the original value of the attribute, the copy of the attribute, the original value of the device, and the copy of the device, that is, it is assumed that there is a copy of the abstract device at the far end, such as a server and an APP, but these "copies" are not necessary, and the implementer decides whether to implement such a copy at the far end according to the actual requirements. The usability of the protocol is not affected as long as the behavior of the remote end is consistent with that described by the protocol.

(3) In one embodiment, the interface is defined with respect to

Taking the foregoing definition example, an interface represents a particular function, and an interface is defined by an interface index, an interface name, and a set of attributes. The interface index is a unique identifier of the interface type, and each interface is assigned a specific index; interface names are names defined for memory convenience, and are used for description only; the attribute set defines the specific content of the interface, directly defines the function of the interface, and the first attribute item of each interface is an interface version. Only one instance is allowed to exist in a device for a particular interface.

Table 1 defines an interface, and includes basic information of an interface, and overview information of an attribute set.

Table 1 interface definition table

(4) In one embodiment, interface attributes are defined

In an interface, each attribute is assigned an index that is unique within the interface as a unique identifier for the attribute. Also, for convenience of description, an attribute name is defined for each attribute. The type of the attribute may be arbitrary in principle, may be a simple data type or a complex structure, but needs to be explicitly specified in the definition of the attribute. An attribute may have four basic operations, but in practice only one or some of these four basic operations are often required for a particular attribute, so it is also necessary to define which basic operations the attribute supports when defining the attribute. In addition, to increase flexibility, additional data is defined during basic operation. Since attributes often relate to functions of a device, the relationship of the attributes to the functions of the device also needs to be specified when defining the attributes. When the attribute is an array or structure, an operation on a portion of the attribute may be selected, at which time only one element or one of the data items within the array may be operated on. Table 2 illustrates the definition of two attributes, which can be performed according to this table when performing the attribute definition.

Table 2 attribute definition table

(5) Three interfaces are predefined in one embodiment

Taking the foregoing example, the functionality of the device is implemented through the interface. For the basic operation of the device, at least three predefined interfaces are defined-basic interface, server direct connection interface and container interface. The basic interface between any one work and the equipment in the remote management system of the household appliance is realized. The basic interface abstracts the common characteristics of the devices, through which the type of device, the version of the protocol employed, the version of the device itself, and the list of other interfaces supported by the device, etc. can be known. The server direct connection port shows that the device has the capability of directly establishing a communication channel with the server, and the device server realizing the interface needs to carry out additional processing; the device implements a container interface that indicates that the device can be added to the self-device under it as a parent device.

1) An example of a basic interface

The basic interface is an interface to be implemented by each device, which contains basic information of the device, and table 3 and table 4 are definitions of the basic interface.

Table 3 interface definition table of basic interfaces

Table 4 attribute definition table of basic interface

2) An example of a server direct connection port

Implementing a server direct connection port indicates that a device is able to establish communication directly with a server, thus requiring that the device have some specific functionality. These specific functions are defined by server direct connection ports. In addition, because of the special nature of the interface of the direct connection port of the server, the equipment for realizing the interface also has a special function, namely, when the equipment works, the equipment tries to establish a link of calling interface Socket with a specific network address, and after the connection is successfully established, basic information about the equipment is sent to the server. Tables 5 and 6 are server direct connection port definitions.

Table 5 interface definition table for server direct connection port

Table 6 attribute definition table of server direct connection port

3) An example of a container interface

Implementing the container interface indicates that a next-level device may exist under the device, the container interface only provides the existence of the next-level device of the device, and does not provide support for how to manage the next-level device, and corresponding functions are often related to specific devices, so that devices implementing the container interface generally define other interfaces and implement other interfaces to support related functions. Tables 7 and 8 are definitions of container interfaces.

Table 7 interface definition table of container interfaces

Table 8 attribute definition table of container interface

(6) In one embodiment, the communication protocol is defined

In one example, assume that communication occurs between a server direct connection device and a server. The communication is carried out by calling an interface Socket, the data is transmitted in a Json format, and the basic structure of the data transmission is as follows:

where "key" is an identification string, each representing a type of communication. Such as "attribute" for the attribute base operation key. "data" is specific content of communication, and is different from one key to another.

The operations on the device are all accomplished through four basic operations on the attributes. The key is a fixed value, and the data is a structure body and contains the content related to the attribute operation. The structure of data is as follows:

"path" is the path of the device, and "application" is additional information given by the operation initiator, which returns the same value when the responder responds to the operation, and can be used to assist in completing the communication, null when not in use. "accType" indicates an operation type, and "content" is operation-related content, and may have different structures according to different "content" of "accType", and specific definitions are described in detail later in this section. The definition and the specific content of "content" are related only to the attribute operation, and are not related to the transmission process, that is, data can be sent to the destination without viewing the content, and the response should be able to be accurately returned to the initiator.

Although "content" is defined differently according to the transmission type accType, three basic contents are included as follows:

the interface is an interface index, which is an int32 type number and represents the interface where the operated attribute is located. "index" is string-type data representing an index of an attribute, and will also include additional information when an attribute part is operated on. For example, "index" = "2" when accessing the attribute whole with the attribute index of 2; "index" = "5[1]", when accessing the 2 nd element of one array with attribute index of 5 (array index numbered from 0); when accessing a part with the name sub of the attribute with the attribute index of 6, "index" = "6.Sub". The "addition" is to access additional information, and is defined when the attribute is defined, and the value null is taken when the attribute is not used. This part of the content should be independent of the transmission process and only related to the operation of the properties themselves.

In addition, two items of content may also appear in the content, depending on the direction of data transmission and whether it is a response of an operation:

"result" appears when the transmission is a response, and indicates whether the operation initiated before succeeds and the reason for failure is an int32 type number, and the specific value and meaning are shown in table 9."value" occurs when the sender of the transmission is the data provider, whose type matches the attribute or part of the attribute specified by "index", and the value is the value to be transmitted.

Table 9 results of execution of the attribute operation

result	Description of the invention	result	Description of the invention
				200	Successful operation	700	The interface is not present
300	The device is absent	800	Attribute absence
				400	Device response timeout	900	Attribute operation is not supported
500	Device busy, refusal operation	1000	The server does not establish a link
				600	Equipment failure	1100	Server response timeout

based on the various previously defined examples, the management and control process of the present invention will be further described in connection with the specific implementation of the operations of the intelligent switch, the management and access of the intelligent thermometer, etc.

Example 1: taking a remote management intelligent switch as an example, it is assumed that a household appliance such as a washing machine, a dish washer and the like relates to the intelligent switch, so as to realize intelligent control of the household appliance, and the intelligent switch has two switch buttons, so that a user can realize opening and closing of the two switches through a physical switch, can realize remote opening and closing of the switches through remote networking operation of a mobile phone, and can also view the current switch state remotely at the remote end through the mobile phone.

It is assumed that this embodiment defines a "smart switch interface" that implements both the basic interface and the smart switch interface. The attribute definition of the basic interface is shown in table 10.

Table 10 attribute definition table of basic interface of intelligent switch

The definition of the intelligent switch interface and the definition of the attribute of the intelligent switch interface are shown in tables 11 and 12, respectively.

Table 11 Intelligent switch interface definition table

Table 12 Intelligent switch interface attribute definition table

If the mobile phone remotely opens the intelligent switch, the mobile phone is downloaded in a passive manner:

/>

the intelligent switch responds to the passive download response mode after executing the opening operation action:

example 2: if the expandable household appliance remote management system needs to be connected with the intelligent thermometer equipment in the later period, only a manufacturer is required to release a definition table in a corresponding format at the moment, the household appliance remote management system can be connected with the intelligent thermometer in a compatible and expandable manner, and the household appliance remote management system has expansibility. The intelligent thermometer can detect the current temperature, and alarms when the temperature exceeds a certain range, namely when the temperature exceeds a certain preset threshold value, the thermometer alarms, and a user can set whether to enable the alarm.

The basic interface definitions issued by the smart thermometer manufacturer are shown in table 13, and the other interface and attribute definitions are shown in tables 14 and 15.

if the current temperature is 26.5 ℃, the intelligent thermometer responds by a passive download response mode:

based on the above specific definition modes of management control, the protocol and structure of the home network for accessing and managing the smart home are constructed, and an example of an application scenario of the scheme provided by the invention is shown in fig. 1:

taking cloud server intermediary management control through the cloud end as an example, a computer or a mobile phone (even other household appliances and other devices) sends management and control instructions through installed application software APP for managing or controlling intelligent household appliances, such as adding one or more household appliances into a household network or performing management control operation on household appliances in the household network, and the like, a cloud server end transmits the control or management instructions to corresponding household fixed terminal connection equipment through a network (internet, the Internet of things and the like) according to the transmitted instructions, and the household fixed terminal performs operation processing on physical equipment such as an intelligent socket, a washing machine, a water heater and the like in the household appliance network of the intelligent household or to be connected into the household appliance network.

The implementation process of the present invention will be described with reference to the main step flow of one embodiment of the expandable home appliance remote management method of the present invention shown in fig. 8.

Step S110, defining a data set representing a function of each physical entity device as an abstract device and defining a specific function of each abstract device as an interface according to a function of a home appliance device having the physical entity.

Specifically, defining attributes of the home appliance includes interface definitions for the home appliance, and interface attribute definitions.

Wherein management control and operation state monitoring of an actual physical device can be performed based on the abstract device, and the abstract device (i.e., the functional data set) recorded in the physical device can be referred to as a device raw value. Further, the abstract device may store a corresponding copy in the server, referred to as a device copy.

Further, to increase flexibility in device definition, "interfaces" are defined, each representing a particular function of the abstract device. Different devices may have the same functionality. An example of a defined interface: the predefined three special interfaces are a basic interface, a server direct connection interface and a container interface in sequence.

Further, an interface contains a series of attribute items, and the set of attribute items describes the function of the interface in detail, and the attribute items are basic units for data access.

Specific definition procedures and content refer to the examples previously described for device definition, the examples previously described for interface definition, and the examples previously described for interface attribute definition.

Step S120, based on the defined attribute of the interface in the abstract device, defines the device operation of active or passive data transmission between the current physical entity device and the remote end via the communication connection.

Specifically, the operation on the home appliance is completed based on the basic operation of the attribute, wherein the data transmission from the home appliance to the remote end is uploading, the data transmission from the remote end device to the home appliance is downloading, the operation actively initiated by the home appliance is active operation, the operation actively initiated by the remote end device is passive operation, and the basic operation comprises: active upload, active download, passive upload, and passive download.

After the attribute of each interface in the abstract device is defined, the specific content of one interface can be finally embodied through the attribute, so that the operation on the device can be finally generalized as the operation on the attribute. The invention refers to the attribute in the original value of the equipment as the original value of the attribute, and the attribute in the copy of the equipment is called as the copy of the attribute, so that the operation of the equipment can be finally summarized as the data exchange between the original value of the attribute and the copy of the attribute.

Further, with respect to the operation of the attribute, the present invention describes the related operation from the viewpoint of the device. The operation initiator or destination other than the device itself is referred to as the "remote end", the entity in the process of operation that assists in completing the communication between the device and the remote end is referred to as the "intermediary", and according to the actual situation, there may be, or may not be, multiple intermediaries involved in the data exchange process. The transfer of data from the device to the remote end is called uploading and the transfer of data from the remote end to the device is called downloading. The operation actively initiated by the device is active and the operation actively initiated by the remote is passive. Thus, four basic operations of the attribute, namely active upload AU, active download AD, passive upload PU and passive download PD, can be defined, and the functions of one device are completed through the four basic operations of the attribute.

One example of this is: the household appliance, namely the physical entity equipment, is in communication connection with a far end (far end equipment); the communication may be performed by means of socks.

Specific definition procedures and content refer to the examples described above for device operation definition and the examples described above for definition of communication protocols.

Step S130, based on the defined attribute of each physical entity device and the device operation, a corresponding control operation is performed between each physical entity device and the remote end as required.

One example of this is: when another home appliance is accessed, the remote device may operate the accessed other home appliance based on the attribute of the other home appliance. For example, the other household appliance is an intelligent thermometer, and the remote equipment can control the intelligent thermometer based on the attribute of the intelligent thermometer, and the intelligent thermometer detects the current temperature and displays the temperature; the intelligent thermometer also has an alarm function, and when the temperature exceeds a preset threshold value, the intelligent thermometer alarms and indicates, etc.

Further, the remote device is a cloud server, a mobile phone terminal, a computer and a home fixed terminal.

Specific control operations various operations for the device as defined, see the examples described above with respect to the attribute definition and examples 1 and 2.
