In a possible implementation form of this application, the LiFi subassembly can also be used for sheltering from the filter plate of light entry during the selection communication according to the flag bit information that the communication opposite terminal sent to improve the data transmission safety of LiFi communication.
The communication device of the electronic device provided in the embodiment of the present application is further described below with reference to fig. 7.
Fig. 7 is a schematic structural diagram of a LiFi component in a communication device of an electronic device according to an embodiment of the present disclosure.
For convenience of description, fig. 7 shows only a specific structure of the LiFi component in the communicator of the electronic device, and other components in the communicator of the electronic device are not shown.
As shown in fig. 7, on the basis of the above embodiment, the LiFi assembly 140 may further include: a first amplifier 142, a receiver 143, and a baseband processor 144.
Wherein the amplifier 142 is connected to the photodiode 141.
The receiver 143 is connected to the amplifier 142, and is configured to receive the signal amplified by the amplifier 142;
the baseband processor 144 is connected to the receiver 143 for processing the signal received by the receiver 143.
It should be noted that after the light carrying the LiFi signal is acquired, the photodiode 141 may convert the light signal into an electrical signal, and then the amplifier 142 connected to the photodiode 141 may amplify the electrical signal generated by the photodiode 141, so as to facilitate subsequent processing. After acquiring the signal amplified by the amplifier 142, the receiver 143 may further process the received signal and send the processed signal to the baseband processor 144; the baseband processor 144 may perform parsing on the LiFi signal transmitted by the receiver 143 to obtain the LiFi information carried by the LiFi signal.
Further, the baseband processor 144 may also be configured to control the driving component 130, so that the driving component 130 controls the positions of the blue light filter 121, the green light filter 122 and the red light filter 123. The baseband processor 144 can determine the filter for blocking the light inlet 110 according to the current communication requirement, and then control the driving assembly 130 to drive the filter to move to the first position, and drive other filters in the filter assembly 120 to move to the second position.
For example, if the baseband processor 144 determines that the filter for blocking the light inlet 110 is the red filter 123 according to the current communication requirement, the driving component 130 can be controlled to drive the red filter 123 to move to the first position, and drive the blue filter 121 and the green filter 122 to move to the second position.
Further, in a possible implementation form of the embodiment of the present application, the red light filter 123 is a main filter, and the default position is a first position; blue light filter 121 and green light filter 122 are auxiliary filters, and the default position is the second position.
As a possible implementation manner, the red light filter 123 may be set as a main filter whose default position is the first position, so as to receive the LiFi information at any time; and sets the blue light filter 121 and the green light filter 122 as an auxiliary receiving channel whose default position is the second position, so that the blue light filter 121 or the green light filter 122 can be driven to move to the first position and the red light filter 123 can be driven to move to the first position only when necessary.
Further, when the opposite communication terminal sends the LiFi information to the electronic device, the flag information can be generated and sent to the electronic device according to the light wavelength of the LiFi information carrier used by the opposite communication terminal, so that the photodiode 141 can receive the first optical signal transmitted by the opposite communication terminal, the baseband processor 144 is further configured to obtain the flag information included in the first optical signal, and determine the target filter at the first position according to the flag information, and further control the driving component to drive the target filter to move to the first position, and drive other filters in the filter component to move to the second position, wherein the first optical signal is red light.
The first optical signal refers to an optical signal transmitted by a communication opposite terminal acquired by the electronic device for the first time.
It should be noted that, because the filter 123 and the red light filter are the main receiving channel, the default position is the first position, when the communication device 100 of the electronic device establishes communication with a communication peer for the first time, the flag bit information sent by the communication peer through the red light can be acquired, the baseband processor 144 can analyze the acquired flag bit information, determine the target wavelength of the optical signal used by the communication peer in the subsequent communication process, further determine the filter corresponding to the target wavelength as the target filter, and when it is determined that the current position of the target filter is not the first position, control the driving component 130 to drive the target filter to move to the first position, and drive the filter whose current position is the first position to move to the second position.
For example, when it is determined that the flag bit information corresponding to the blue light is "1" (that is, it is determined that the target wavelength of the optical signal used by the opposite communication terminal in the subsequent communication process is the wavelength corresponding to the blue light), the target filter may be determined as the blue light filter 121, and then the driving component 130 is controlled to drive the blue light filter 121 to move to the first position and drive the red light filter 123 to move to the second position.
Further, the communication device 100 of the electronic apparatus according to the embodiment of the present application may further have a LiFi sending function, so that in a possible implementation form of the embodiment of the present application, as shown in fig. 8, on the basis of the embodiment shown in fig. 7, the LiFi component 140 may further include: a blue light emitter 145, a green light emitter 146, and a red light emitter 147.
The baseband processor 144 may also be configured to determine a target emitter corresponding to the target filter, and control the target emitter to emit light carrying the LiFi signal.
The target emitter is an emitter which emits light with the same color as the target filter. For example, if the target filter is the red filter 123, the target emitter may be determined to be the red emitter 147.
It should be noted that the blue light emitter 145, the green light emitter 146, and the red light emitter 147 may be connected to the baseband processor 144, so that each emitter can send the LiFi signal according to the control command of the baseband processor 144. The blue light emitter 145 may emit blue light as a carrier of the LiFi signal, the green light emitter 146 may emit green light as a carrier of the LiFi signal, and the red light emitter 147 may emit red light as a carrier of the LiFi signal.
In this embodiment, the baseband processor 144 may determine, according to the color of the target filter used in the current communication process, a target emitter used when the electronic device emits the LiFi signal, that is, the color of light emitted by the target emitter is the same as the color of the target filter.
Further, as shown in fig. 9, on the basis of the above embodiment, the LiFi assembly 140 in the communication device 100 of the electronic apparatus of the embodiment of the present application may further include a switch 148, wherein the switch 148 is configured to switch between a transmitting path and a receiving path of the LiFi assembly 140.
It should be noted that, when the communication device 100 of the electronic device of the embodiment of the present application has both LiFi sending and LiFi receiving functions, the blue light emitter 145, the green light emitter 146, and the red light emitter 147 may share the baseband processor 144 with the receiver 143, so that the baseband processor 144 may be connected to the blue light emitter 145, the green light emitter 146, the red light emitter 147, and the receiver 146 through the switch 148, respectively, so as to connect the baseband processor 144 to the receiver 143 (i.e., switch to a receiving path) through the switch 148 when the electronic device receives the LiFi signal; when the electronics send a LiFi signal, the baseband processor 144 is connected to the target emitter (i.e., switched to the emission path) via the switch 148.
The utility model provides an electronic equipment's communication device, through setting up the default position with ruddiness filter piece to primary importance for the position information that the opposite end of communication and ruddiness sent can be received to the LiFi subassembly, later through the position information that the baseband processor sent according to the opposite end of communication, select and communicate the target filter piece that is used for sheltering from the light entry to the opposite end communication in-process, and then control drive assembly drive target filter piece and remove to primary importance, other filter pieces in the drive filter piece subassembly remove to the second place.
