The configuration information is a Service Set Identifier (SSID), containing the home appliance information and MAC information. In some optional embodiments, first <NUM> characters of the SSID carry the home appliance information; and last <NUM> characters of the SSID carry the MAC information.

The technical solution according to embodiments of the present invention has the following beneficial effects.

The home appliance transmits the SSID with the home appliance information and MAC information to the user terminal when sending a network configuration broadcast message, instead of carrying the home appliance information and MAC information, as two separate parameters, in the network configuration broadcast message. The user terminal may obtain the home appliance information and the MAC information of the home appliance by only identifying SSID.

The home appliance information and the MAC information are carried by the SSID, which reduces the occupation of network resources, lowers the network load and improves network operation efficiencies.

The description below and accompanying drawings fully illustrate specific embodiments of the invention, to enable one skilled in the art to implement the embodiments. Modifications, such as structural, logical, electrical and process modifications, can be made in other embodiments. The embodiments only represent some possible variations.

Herein, these embodiments of the invention may be individually or generally represented by the term "invention" for the sake of convenience; moreover, if more than one invention is disclosed actually, it is not intended automatically to limit the application scope to any individual invention or inventive concept. It should also be noted that the relationship terminologies such as "first", "second" and the like are only used herein to distinguish one entity or operation from another, rather than necessitate or imply that the actual relationship or order exists between the entities or operations. Furthermore, terms of "include", "comprise" or any other variants are intended to be non-exclusive. Therefore, a process, method, article or device including a plurality of components includes not only the listed components but also other components that are not enumerated, or, also include the components inherent for the process, method, article or device. Without other limitations, the component defined by the statement "comprising (including) one. " does not exclude the case that other similar components may exist in the process, method, article or device having the above component. The embodiments in the specification are described in a progressive manner. Each of the embodiments is mainly focused on describing its differences from other embodiments, and references may be made among these embodiments with respect to the same or similar portions among these embodiments. As for the device and product disclosed in the embodiment, since they correspond to the part disclosed in the embodiment, the description is relatively simple, and the relevant contents refer to the part of the explanation of the method.

The user terminal herein provides display and may be operated directly by a user, for example, an intelligent mobile phone, intelligent watch, PC machine, tablet PC, etc.; the home appliance herein refers to the one with a built-in wireless communication module, or the one interworking with an exclusive wireless communication module, including an intelligent air conditioner, intelligent TV, intelligent refrigerator, intelligent oven, etc. Certainly, the present invention is directed at the control over the home appliance in a home environment. However, rapid network configuration and control may also be performed on other non-home appliances in the similar control environment, such as various intelligent mechanical devices in a factory.

Currently, there is provided a network configuration method for home appliance. In this solution, by defining characters in SSID, the common information in the network configuration process for home appliance, i.e., the home appliance information and the MAC information, is carried by SSID.

The home appliance information, different from the MAC information, needs to be notified in the process of network configuration for home appliance, such as a home appliance identifier, home appliance type, machine code, home appliance brand, home appliance model, etc..

The MAC information refers to the one with a MAC address of the home appliance, and carries all or part of the MAC address of the home appliance.

In some exemplary embodiments, a network configuration method for home appliance, applied to home appliance side, includes:
sending configuration information of AP; where the configuration information carries home appliance information and MAC information.

Specifically, the configuration information is sent in the manner of broadcast, multicast or unicast.

Further, the configuration information includes SSID and a password (PWD); the configuration information may be carried by SSID or PWD.

If the home appliance information and the MAC information are carried by the PWD, such a fixed carrying method may cause the PWD to be broken easily. In addition, for the sake of network safety, the PWD is not constant usually, and should be amended frequently. Therefore, in the following embodiments, the SSID is used for carrying the home appliance information and the MAC information.

The SSID has two functions of representing an identifier of a subnetwork, which helps find the subnetwork, and carrying the home appliance information and the MAC information. It is assumed that the home appliance carries SSID in the form of broadcast by sending the network configuration broadcast message. The home appliance transmits the home appliance information and MAC information to the user terminal by carrying only SSID when sending a network configuration broadcast message, instead of carrying the home appliance information and MAC information, as two separate parameters, in the network configuration broadcast message. The user terminal may obtain the home appliance information and the MAC information of the home appliance by only identifying SSID. The home appliance information and the MAC information are carried by the configuration information, such as SSID, which reduces the occupation of network resources, lowers the network load and improves network operation efficiencies.

The SSID carries the home appliance information, including one or more information of home appliance identifier, home appliance type, machine code, home appliance brand and home appliance model; the MAC information carries all or part of the MAC address of the home appliance.

How to carry the home appliance information and the MAC information by the SSID will be explained below.

In some optional embodiments, the first <NUM> characters of the SSID carry the home appliance information; the last <NUM> characters of the SSID carry the MAC information.

Optionally, the home appliance information includes: a home appliance brand and a home appliance identifier.

Specifically, the SSID has such a format as home appliance brand-home appliance identifier-MAC information.

The "home appliance brand-home appliance identifier" has a length of <NUM> characters, and "-MAC information" has a length of <NUM> characters; for example, haier-ASI12BA98-xxxxxx.

Further, the home appliance brand and the home appliance identifier in the SSID are divided by an English punctuation "-"; the home appliance identifier and the MAC information are divided by the English punctuation "-". "haier" is the home appliance brand, "ASI12BA98" is the home appliance identifier, and "xxxxxx" is the last <NUM> characters of the MAC address.

Due to the relatively lengthy MAC address, all MAC address is carried in the SSID, which causes the problem of the lengthy SSID when the user terminal displays the SSID. Therefore, the length of the SSID is defined in the above-mentioned embodiments, and the preferable SSID structure and the information carried by different character positions in SSID are given in different embodiments.

By sending the SSID carrying the home appliance information and the MAC information, the home appliance enables the user terminal to obtain the home appliance information and the MAC information by analyzing the SSID while obtaining the SSID. In this way, the content of the parameter carried by the network configuration message sent by the home appliance is simplified, for example, the network configuration broadcast information. Additionally, the user terminal may obtain the home appliance information and the MAC information by only identifying such a parameter as SSID, which simplifies the identification flow and improves the identification speed.

The network configuration method for home appliance is applied to a user terminal side.

In some exemplary embodiments, a rapid network configuration method for home appliance includes:
receiving a broadcast which is sent by the home appliance and carries configuration information of a wireless access point AP; where the configuration information carries home appliance information and MAC information.

Further, the configuration information includes SSID and PWD; the configuration information may be carried by SSID or PWD.

If the home appliance information and the MAC information are carried by the PWD, the PWD may be broken easily. In addition, for the sake of network safety, the PWD is not constant usually, and should be amended frequently. Therefore, in the following embodiments, the SSID is used for carrying the home appliance information and the MAC information.

The SSID has two functions of representing an identifier of a subnetwork, which helps find the subnetwork, and carrying the home appliance information and the MAC information. The user terminal may obtain the home appliance information and the MAC information of the home appliance by only identifying SSID. The home appliance information and the MAC information are carried by the configuration information, such as SSID, which reduces the occupation of network resources, lowers the network load and improves network operation efficiencies.

The configuration information is a service set identifier (SSID), containing the home appliance information and MAC information.

How to use the SSID carrying the home appliance information and the MAC information to implement rapid network configuration for home appliance will be explained below by embodiments.

The home appliance establishes an AP and broadcasts the configuration information of its AP through the wireless module. The user terminal obtains all surrounding home appliances which may establish AP through the wireless module by applications, and displays all the home appliances in the form of a list through an application interface to enable the user to select the home appliance to be connected and controlled. After the user selects a target home appliance at the application, the user terminal performs a rapid network configuration therewith according to the obtained configuration information of this target home appliance. After the target home appliance and the user terminal form a network successively, the target home appliance would report its operating state information to the user terminal, and the application at the user terminal would display a control interface correspondingly, so as for the user to control the target home appliance through this control interface directly. The application obtains and collectively displays the network configuration information of the home appliance. The user may not only know the information of the controllable home appliance by the application, but also form a network with the home appliance more conveniently, to perform corresponding control; when the user needs to control other home appliances, the connection with the current home appliance may be disconnected rapidly, and connection with the new target home appliance may be established directly.

<FIG> is a flow chart of a rapid network configuration network for home appliance according to the exemplary embodiments of the present invention.

In some exemplary embodiments, as shown in <FIG>, a rapid network configuration method for home appliance, applied to the home appliance end, includes the following steps.

In step S101, a wireless communication module is set to enter an operating mode.

Optionally, before the step S101, the method further includes an operation procedure of self-detection, i.e., detecting a connection of the home appliance with its wireless communication module to ensure a normal connection, which may be implemented by handshake communication based on the home appliance and the wireless communication module.

An alarm is triggered if it is detected that the home appliance is communicated with the wireless communication module abnormally. For example, an alarm is raised by a buzzer of the home appliance; optionally, after the alarm is triggered, an error code is fed back to a cloud server, so as to wait for a corresponding recovery service provided by the cloud server.

The method goes to the step S101 If it is detected that the communication between the home appliance and the wireless communication module is normal. In the step S101, the wireless communication module is set to be in the operating mode.

In step S102, the configuration information of the access AP is broadcasted; where the configuration information carries the home appliance information and the MAC information.

The provision of the home appliance information is to enable the user terminal to display the home appliance information for user selection. The home appliance information includes: home appliance brand, and home appliance type identifier; the MAC information may be part of the MAC address; optionally, the configuration information may also include a network access password; where the home appliance brand, the home appliance type identifier and the MAC information are sent by SSID, and the user terminal may obtain the above-mentioned information by analyzing the SSID.

The SSID has such a format as home appliance brand-home appliance identifier-MAC information.

Further, the SSID has a length of <NUM> characters. The "home appliance brand-home appliance identifier" has a length of <NUM> characters, and "-MAC information" has a length of <NUM> characters; for example, haier-ASI12BA98-xxxxxx. Further, the home appliance brand and the home appliance identifier in the SSID are divided by an English punctuation "-"; the home appliance identifier and the MAC information are divided by the English punctuation "-". The MAC information is the last <NUM> characters of the MAC address. Due to the relatively lengthy MAC address, all MAC address is carried in the SSID, which causes the problem of the lengthy SSID when the user terminal displays the SSID. Therefore, the length of the SSID is defined in the above-mentioned embodiments, and the preferable SSID structure and the information carried by different character positions in SSID are given in different embodiments.

In step S103, a network configuration request sent by the user terminal is received;
a network connection with the user terminal is established.

In some illustrative embodiments, after the network connection with the user terminal is established in step S103, the method further includes the following steps.

In step S104, operating state information is sent to the user terminal.

Specifically, the two parties report the current operating state at an regular interval, for example every five seconds, after the network connection. It is assumed that the home appliance is an air conditioner, the operating state to be reported may include: air conditioner operating mode, such as cooling/heating/humidifying/dehumidifying, wind speed, such as high/middle/low, wind direction, etc.; or, the two parties report the operating state information firstly after the network connection, and then feeds back the new operating state information to the user terminal in the case that there is a change in the operating state information.

In step S105, if a control instruction sent from the user terminal is received, according to the control instruction, the operating state is adjusted, and the adjusted operating state information is sent to the user terminal.

The user may adjust the operating state of the home appliance through the control interface displayed at the user terminal. After the operating state of the home appliance is adjusted according to the control instruction sent from the user terminal, the adjustment is fed back to the user terminal, to enable the user to know the adjustment result and the latest operating state of the home appliance in time.

<FIG> is a flow chart of a rapid network configuration method for home appliance according to one exemplary embodiment.

In some exemplary embodiments, as shown in <FIG>, a rapid network configuration method for home appliances, applied to the user terminal, includes the following steps.

In step S201, a broadcast from the surrounding home appliance is monitored, including the configuration information of the AP with an access to the home appliance; where the configuration information carries the home appliance information and the MAC information; the home appliance information includes the home appliance brand and the home appliance type identifier; the MAC information is the last <NUM> characters of the MAC address; optionally, the configuration information may also include a network access password; the home appliance brand, the home appliance type identifier and the MAC address are sent by SSID, and the user terminal may obtain the above-mentioned information by analyzing the SSID.

In step S202, the SSIDs of all monitored home appliances are displayed, for user selection.

Optionally, the method further includes the step of screening the home appliances to be displayed according to the home appliance brand carried by SSID, to elect the home appliance according with the preset brand, and reject the home appliances with other brands; the type identifier of the home appliance of SSID is to enable the application to know and display the type of the home appliance, such as the air conditioner, washing machine, TV, etc..

When the user opens the application of the user terminal, the application may automatically search for all the home appliances in the surrounding environment. If the application finds a plurality of home appliances, these home appliances provide AP for connection; if during the use of the application, it is monitored that a new home application provides AP, the application may prompt the user to look for the new home appliance forwardly, and update the home appliance list to be selected by the user.

The user terminal may do a reverse lookup on the home appliance type at the cloud server or locally only according to the MAC address instead of according to the home appliance type identifier. Therefore, in the present embodiment, the home appliance type identifier is optional; but in practical operations, the type identifier of the home appliance corresponding to the MAC address is not entered and stored in advance, so usually, the type identifier of the home appliance is an essential parameter, and the application knows and displays the home appliance type based on this parameter.

In step S203, a network configuration request is sent to all the home appliances, to establish a network connection.

In some illustrative embodiments, after the network connection with a certain home appliance is established in step S203, the method further includes:.

In the present embodiment, the control interfaces corresponding to different home appliances are stored locally or at a cloud server. The control interface calling procedure and solution are not repeated herein. It should be noted that no matter how the control interface is called or displayed, the control interface needs to display the current operating state information, such that the user knows the operating state of the home appliance, and performs control over the home appliance according to this operating state.

In some illustrative embodiments, after the network connection with the certain home appliance is established in step S203, the method further includes:.

The another home appliance is the one which is monitored among all home appliances, other than the certain home appliance.

In the application, a plurality of home appliances which provides AP and may be connected and controlled is displayed collectively. Therefore, when the user needs to control another home appliance, the user only needs to select the home appliance to be connected and controlled from the list. Once the user clicks other home appliances, the switch signal is generated. The application disconnects the current network connection with the original certain home appliance according to the switch signal, thereby triggering the flow of network connection with another home appliance. The network connection flow herein and the subsequent control process are similar to the above-mentioned flows, and are not repeated herein.
