That is, home controller when selecting the first communication pattern, can only consider each logical of household appliance support The status information of letter pattern, to determine the first communication pattern with the household appliance into row data communication, without regard to family The current stability for the first communication pattern that front yard controller is supported.

As the third optional method of determination, home controller is according to the shape of each communication pattern of the home controller The status information for each communication pattern that state information and household appliance are currently supported, to determine with the household appliance into line number According to the first communication pattern of communication.

That is, home controller when selecting the first communication pattern, both considered that its own currently supports it is each logical The status information of letter pattern, it is further contemplated that the status information for each communication pattern that household appliance is supported.In such manner, it is possible to so that selection The property taken into account of the first communication pattern gone out is strong, can more improve the success carried out data transmission between home controller and household appliance Rate.

Wherein, the status information of communication pattern includes but not limited to：Signal strength, communication pattern whether open (or communication Whether pattern is in enabled state).

In general, if a certain communication pattern is in enabled state, and the signal strength of the communication pattern meets the communication The corresponding signal strength requirement of pattern, then the communication pattern can be used as the first communication pattern to be selected.

In practical application, optionally, home controller can also be selected according to the preconfigured data-transmission mode of household appliance Strategy is selected to determine the first communication pattern.

For different household appliances, preconfigured data-transmission mode selection strategy may not Equally.For example, being limited by the household appliance of the signal barrier and routing radiation scope of metope being affected, selection is passed using light Defeated communication pattern is as preferred data-transmission mode, and in this case, optical transport communication pattern is determined the by home controller One communication pattern.For another example being limited by the signal barrier of metope and routeing the smaller household appliance that influences of radiation scope, selection Using wireless communications mode such as WIFI communication modes as preferred data-transmission mode, in this case, home controller will Wireless communications mode determines the first communication pattern.

As a kind of specific implementation mode, the determination communicates mould with the household appliance into the first of row data communication Formula, including：

Home controller obtains the data-transmission mode selection strategy that household appliance is configured in networking；

Wherein, the data-transmission mode selection strategy includes at least one of following strategies：

In an optional embodiment, the preconfigured of each household appliance is being locally stored in the home controller Data-transmission mode selection strategy.When the home controller receives the control instruction for certain household appliance, from local Inquiry data-transmission mode selection strategy corresponding with the household appliance.

In another optional embodiment, in the first equipment being connect with the home controller, it is stored with each family The preconfigured data-transmission mode selection strategy of electric equipment.When the home controller is received for certain household appliance When control instruction, from first equipment query data-transmission mode selection strategy corresponding with the household appliance.Here, described First equipment can be memory or server or other-end.

In the present embodiment, the mobile terminal can be long-range mobile terminal.

It should be noted that above-mentioned mobile terminal is associated with above-mentioned household appliance or matches.Namely Say, only receive match with household appliance or associated mobile terminal send control instruction, the household appliance just meeting Execute the control instruction.Household appliance actively sends request message to mobile terminal or when instruction message, and to its phase Pairing or associated mobile terminal send the request message；Wherein, the request message is for asking mobile terminal to provide Control instruction.Wherein, the instruction message is used to send the control instruction that household appliance is made to mobile terminal.

As an implementation, the acquisition for mobile terminal control information input by user for household appliance is based on institute It states control information and generates control instruction, the control instruction is sent to home controller by mobile data network.

In the present embodiment, the household appliance includes at least life kind household appliance, amusement class household appliance；For example, institute It includes but not limited to electric cooker, electric pressure cooker, refrigerator, water heater, air purifier etc. to state life kind household appliance；The joy Happy class household appliance includes but not limited to TV, speaker, high definition player etc..

Step 102：Home controller sends the control instruction by the first communication pattern to the household appliance, and examines It surveys in preset time threshold and whether receives the response data that the household appliance is sent.

Here, the preset time threshold can be set by home controller according to itself actual needs, may be used also To be adjusted to the already present time threshold according to the status information of currently employed communication pattern by home controller.Example Such as, preset time threshold can be set as in 1~60 second any one second.

In a specific embodiment, home controller is determined and household appliance carries out data transmission first communicates mould After formula, control instruction is sent to the household appliance by the first communication pattern, detects in preset time threshold and whether receives The response data that the household appliance is sent, according to the response for whether receiving the household appliance transmission in preset time threshold Data are to determine whether carry out the data transmission about this control instruction by the first communication pattern and household appliance.

If that is, not receiving the response data that the household appliance is sent in preset time threshold, judgement passes through First communication pattern cannot be sent to the control instruction to household appliance.

It so, it is possible to be made whether to need the judgement of switch communication mode according to testing result convenient for home controller, Subsequently to use which kind of communication pattern and household appliance completion data to communicate and provide basis for estimation.

Step 103：If home controller receives the response data in preset time threshold, first is continued through Communication pattern and the household appliance are into row data communication；If home controller does not receive the sound in preset time threshold Data are answered, then the first communication pattern are switched into the second communication pattern, are sent to the household appliance by the second communication pattern The control instruction, and the second communication pattern and the household appliance are continued through into row data communication.

Illustratively, first communication pattern is wireless communications mode or optical transport communication pattern, second communication Pattern is optical transport communication pattern or wireless communications mode.

In a specific embodiment, when first communication pattern is wireless communications mode, second communication pattern For optical transport communication pattern when, it is described that first communication pattern is switched into the second communication pattern, including：

LIFI nodes are also responsible for receiving the second optical signal that household appliance is sent, the second optical signals household appliance root The response data determined according to the control instruction is formed；The response data of household appliance is obtained based on second optical signal；And The response data is forwarded to home controller.

Here, the LIFI nodes can send and receive data.

Preferably, the home controller is connected with the LIFI nodes by solid data line.

In this way, without requiring LIFI AP that there is network communicating function, the home controller to pass through with the LIFI nodes Solid data line is connected, and first data transmission that home controller is rapidly determined can be ensured to LIFI nodes In, also ensure that LIFI nodes receive first data；Relative to the first data otherwise such as network data transmission Form is transmitted to for the data transfer mode of LIFI nodes, additionally it is possible to avoid the first data by illegality equipment intercept and capture or decode or The problems such as distorting improves the safety of data transmission.

Wherein, the light emitting devices is the light emitting devices that can emit visible light or black light.

In general, it is seen that light emitting devices needs light source (such as needing to open LED light), and black light emitter is not required to Want light source (need not such as open LED light).

Preferably, when LIFI AP receive the first data, light source is judged whether there is, if there is light source, is based on described first Data are controlled forms the first optical signal with the VISIBLE LIGHT EMISSION device of the LIFI node matchings；If not locating without light source or light source In working condition, then first is formed based on first data control and the black light emitter of the LIFI node matchings Optical signal.It, can not be timely caused by there is currently no light source when so, it is possible that LIFI nodes is avoided to receive the first data The problem of the first data being transmitted to household appliance；In addition, when LIFI nodes can be avoided to receive the first data, because of current light source The embarrassing question caused by light source is voluntarily opened in the case of being not in working condition.

Illustratively, the light source can be LED light, and the black light emitter can be understood as special light hair Injection device, the black light emitter can be transmitted data using black light.

Wherein, corresponding first light frequency of first optical signal follows the variation of the first data and changes.

That is, first optical signal is the signal for changing the first light frequency according to the first data.

Optionally, the wave-length coverage of first optical signal is 480nm to 780nm.

For example, home controller receive by mobile terminal send for household appliance control instruction when, really Fixed the first communication pattern with the household appliance into row data communication is WIFI communication patterns.Home controller is logical by WIFI Letter pattern sends the control instruction to the household appliance, if home controller receives the sound in preset time threshold Data are answered, then continue through WIFI communication patterns and the household appliance into row data communication；If home controller is preset The response data is not received in time threshold, then WIFI communication patterns is switched into optical transport communication pattern, passes through optical transport Communication pattern sends the control instruction to the household appliance, and continues through optical transport communication pattern and the household appliance Into row data communication.

Control method provided in an embodiment of the present invention, when home controller can not pass through the first communication pattern and household appliance When carrying out data transmission, the second communication pattern also can be used and carry out data transmission with household appliance；In this way, relative to home control Device is only capable of with household appliance for carrying out data transmission by single communication pattern, and can not only increase can adopt when carrying out data transmission The diversity of communication pattern, moreover it is possible to ensure the accessibility of data transmission.Since the scene that different communication modes are applicable in is different, And the stability of data transmission is stronger under its applicable scene, so can support first in home controller and household appliance In the case of communication pattern and the second communication pattern, it can select, using different communication patterns, to improve under different scenes The stability of home controller and household appliance into row data communication.
