In a possible implementation manner of the embodiment of the present application, in order to improve transmission quality of optical signals during LiFi communication, the gateway 100 may be installed at the top of a room, for example, the gateway may be integrated in a lighting device, wherein a housing of the lighting device includes a base and a transparent cover that are fastened to each other, one surface of the base is an installation surface for ceiling installation, the opposite other surface is a light reflection surface, the periphery of the light reflection surface of the base is provided with a plurality of first LiFi receivers 120, the middle part of the light reflection surface of the base is provided with a plurality of LED units, one part of the plurality of LED units is a first LiFi emitter 110, and the other parts of the plurality of LED units are used for illumination.

In an embodiment of the present application, the lighting device includes a plurality of LED arrays, a portion of the plurality of LED arrays is the first LiFi emitter 110, and the other portion of the plurality of LED arrays is used for lighting. Therefore, LiFi communication can be realized without additionally arranging an LED lamp, and the internal space and the cost of the lighting equipment are saved. In addition, the plurality of first LiFi receivers 120 are arranged on the periphery of the reflecting surface of the base, so that the plurality of first LiFi receivers 120 can communicate with the household appliances at different corners in the room to acquire the operation information sent by the household appliances at different corners, therefore, the gateway can communicate with the household appliances at different corners in the room to acquire the operation information sent by the household appliances at different corners in the room, the gateway 100 can send the operation information of the household appliances at different corners to the mobile terminal 300, and the mobile terminal 300 can display the operation information of the household appliances at different corners.

In another possible implementation manner of the embodiment of the present application, in order to implement that the gateway 100 communicates with the household appliances at different corners in the room, the gateway 100 may be configured as a rotating device, and when the gateway 100 rotates, the first LiFi receiver 120 and/or the first LiFi transmitter 110 may be driven to rotate, so that the gateway 100 can communicate with the household appliances at different corners in the room.

Specifically, the gateway 100 may include a driving component, where the driving component is configured to drive the first LiFi receiver 120 and/or the first LiFi transmitter 100 to rotate at a preset angular speed, receive operation information sent by different household electrical appliances through the first LiFi receiver 120 in a rotating state, receive a control instruction sent by the mobile terminal 300, and send the control instruction to a corresponding household electrical appliance through the first LiFi transmitter 110 in the rotating state, so as to control the corresponding household electrical appliance to operate according to the control instruction, update the operation information of the household electrical appliance, and send the updated operation information to the gateway 100. Wherein the preset angular velocity is preset.

In the embodiment of the present application, the first LiFi receiver 120, the second receiver 210, and the third receiver 340 may be photodiodes or avalanche diodes, and the first LiFi emitter 110, the second LiFi emitter 230, and the third LiFi emitter 320 are laser emitters.

The avalanche diode can be specifically an Avalanche Photo Diode (APD), the APD has a multiplication effect, and can generate photocurrent which is dozens of times or even hundreds of times larger than that of the photodiode under the action of light with the same size, which is equivalent to a light amplification effect, so that the sensitivity of the LiFi receiver can be greatly improved, and compared with the LiFi receiver adopting the photodiode, the sensitivity of the LiFi receiver adopting the APD can be improved by more than 10 dB. Therefore, in the present embodiment, the APD photodiode is preferably used as a LiFi receiver to receive an optical signal emitted from a LiFi emitter (laser emitter).

In the embodiment of the present application, each of the first, second, and third LiFi emitters 110, 230, 320 may include an LED array and a driver for controlling a depth of the LED array.

The LED array is connected with a driver for controlling the depth of the LED array, is an infrared LED array and works in an infrared frequency band.

In the embodiment of the application, the driver controls the depth of the LED array in the LiFi emitter so as to realize the angle adjustment of the emitted light of the LiFi emitter.

It can be understood that the light emitted by the LiFi emitter has directivity, i.e., light emitting angle, for example, the directivity of infrared light is about 30 degrees, and when the distance between the LED array and the light emitting opening of the LiFi emitter is changed, the directivity of the light is changed. It is understood that the closer the LED array is to the light outlet of the LiFi emitter, the larger the angle of the sent light of the LiFi emitter is, and conversely, the farther the LED array is from the light outlet of the LiFi emitter, the smaller the angle of the sent light of the LiFi emitter is.

In the embodiment of the application, the depth of the LED array in the LiFi emitter is adjusted by setting the driver, so that the directivity of light is adjustable, and the communication quality between the mobile terminal 300 and the gateway 100 can be improved.

The existing LiFi technology carries out data transmission through visible light, and the transmission distance of the visible light is limited, so that the data transmission distance is limited. In view of this problem, in the present application, the light emitted by the first, second, and third LiFi emitters 110, 230, and 320 may be non-visible light, for example, the first, second, and third LiFi emitters 110, 230, and 320 may emit infrared light. Because the wavelength of infrared light is longer than that of visible light and has extremely strong penetration capability, the data transmission distance can be increased by transmitting optical signals through the infrared light.

In the embodiment of the present application, the first LiFi receiver 120, the second receiver 210, and the third receiver 340 may include a photosensitive array, and the angle adjustment of the received light is realized by controlling a part of photosensitive pixels in the photosensitive array to receive the light.

It can be appreciated that the angle at which the LiFi receiver can receive light is different when different photosensitive pixels in the photosensitive array are used to receive light. For ease of understanding, the following detailed description is made with reference to FIG. 5.

FIG. 5 is an exemplary diagram of different photosensitive pixels in a photosensitive array receiving light from different angles. As shown in fig. 5, when receiving the light emitted from the light source a, the left three columns of photosensitive pixels may be used to receive the light, and when receiving the light emitted from the light source b, the right two columns of photosensitive pixels may be used to receive the light.

In this application embodiment, receive light through the partial photosensitive pixel of control in the sensitization array, can realize receiving the angle modulation of light, and then realize the controllable liFi data transmission of directionality.

In order to implement the above embodiments, the present application further provides a gateway.

Fig. 6 is a schematic structural diagram of a gateway according to the fifth embodiment of the present application.

In the embodiment of the application, the shell of the gateway is provided with a mounting surface for ceiling type mounting, so that the gateway can be mounted at the top of a room, and the quality of optical signals sent or received by the gateway can be ensured.

As shown in fig. 6, the gateway 400 includes inside the housing:

a LiFi transmitter 410 for transmitting an optical signal carrying a control command to the household appliance; the control instruction is used for controlling the household appliance to operate and monitoring the operation state to obtain operation information.

And the LiFi receiver 420 is configured to receive an optical signal carrying the operation information sent by the home appliance.

Specifically, when the user wants to control the home appliance device, the user may input a control command for controlling the home appliance device to the mobile terminal bound to the home appliance device in a voice manner, or may input a control command for controlling the home appliance device to the mobile terminal bound to the home appliance device in a manual key touch manner, which is not limited herein. After the user inputs the control command to the mobile terminal, the mobile terminal may transmit the control command to the gateway 400.

For example, in order to ensure the reliability of long-distance transmission between the mobile terminal and the gateway 400, the mobile terminal and the gateway 400 may communicate through a communication module such as 2G/3G/4G/5G, WiFi, so that the mobile terminal may transmit the generated control command to the gateway 400 through the 2G/3G/4G/5G, WiFi module.

Or, in order to ensure the security of data transmission between the mobile terminal and the gateway 400, the mobile terminal and the gateway 400 may communicate through the LiFi module, so that the mobile terminal may send the control command to the gateway 400 by sending the optical signal.

In the embodiment of the present application, after the gateway 400 receives the control instruction sent by the mobile terminal, the optical signal carrying the control instruction may be sent to the household electrical appliance through the LiFi transmitter 410, and accordingly, the household electrical appliance may obtain the control instruction. After the household electrical appliance obtains the control instruction, the household electrical appliance can be controlled to operate according to the control instruction, and the operating state of the household electrical appliance is monitored to obtain the operating information.

The operation information comprises various operation parameter information of the household appliance in the current operation state.
