The communication device of the electronic device provided in the embodiment of the present application is further described below with reference to fig. 9.
Fig. 9 is a schematic structural diagram of a LiFi component in a communication device of an electronic apparatus according to an embodiment of the present disclosure.
For convenience of description, fig. 9 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. 9, on the basis of the above embodiment, the LiFi assembly 140 may further include: a first amplifier 143, a second amplifier 144, a third amplifier 145, a receiver 146, and a baseband processor 147.
Wherein the first amplifier 143 is connected to the first photodiode 1411; the second amplifier 144 is connected to the second photodiode 1412; the third amplifier 145 is connected to the third photodiode 1413.
The receiver 146 is respectively connected to the first amplifier 143, the second amplifier 144 and the third amplifier 145, and is configured to receive signals amplified by the first amplifier 143, the second amplifier 144 and the third amplifier 145;
the baseband processor 147 is connected to the receiver 146 for processing the signals received by the receiver 146.
It should be noted that, after the first photodiode 1411, the second photodiode 1412, and the third photodiode 1413 acquire the light carrying the LiFi signal, the optical signal may be converted into an electrical signal, and then the electrical signal corresponding to each photodiode may be amplified by the amplifier 143, the second amplifier 144, and the third amplifier 145 respectively connected to each photodiode, so as to facilitate subsequent processing. After acquiring the signals amplified by the first amplifier 143, the second amplifier 144, and the third amplifier 145, the receiver 146 may further process each received signal and send the signal to the baseband processor 147; the baseband processor 147 may synthesize and analyze the signals to obtain the LiFi information carried by the signals.
Further, the baseband processor 147 may control the on states of the first amplifier 143, the second amplifier 144, and the third amplifier 145. The baseband processor 147 may set the on state of an amplifier to the off state when it is determined that the amplifier is in the idle state.
Specifically, the baseband processor 147 is configured to detect whether data of the first amplifier 143, the second amplifier 144, and the third amplifier 145 is valid data, and if the data is not valid data, turn off the corresponding amplifier.
The valid data refers to signals acquired by the amplifier and include a LiFi signal.
As a possible implementation manner, the baseband processor 147 may access the first amplifier 143, the second amplifier 144, and the third amplifier 145 through a communication interface (e.g., a General-purpose input/output (GPIO) interface) provided in each amplifier, so as to determine whether data currently received by each amplifier is valid data, that is, whether each current amplifier receives a LiFi signal, and if there is an amplifier that does not receive a LiFi signal, turn off the amplifier, so as to reduce power consumption of the electronic device.
For example, if the baseband processor 147 determines that the data currently received by the second amplifier 144 is not valid data, i.e., the second amplifier 144 does not currently receive the LiFi message, i.e., there is no green light source carrying the LiFi message currently, the second amplifier 144 can be turned off.
Further, in a possible implementation form of the embodiment of the present application, the third amplifier 145 is a main receiving channel, the default state is an on state, the first amplifier 143 and the second amplifier 144 are auxiliary receiving channels, and the default state is an off state.
As a possible implementation manner, the third amplifier 145 corresponding to the red light may be set to be the main receiving channel whose default state is the on state, so as to receive the LiFi information at any time; and the other amplifiers are set as the auxiliary receiving channels whose default states are off states, so that the on states of the first amplifier 143 and the second amplifier 144 can be set to on only when needed, not only can the LiFi information be received at any time through the main receiving channel, but also the power consumption of the electronic device can be reduced.
Further, when the opposite communication terminal sends the LiFi information to the electronic device, the flag information may be generated according to the light wavelength of the LiFi information carrier used by the opposite communication terminal, and sent to the electronic device, so that the baseband processor 147 may control the on state of each amplifier according to the acquired flag information. That is, in a possible implementation form of the embodiment of the present application, the third photodiode 1413 receives flag bit information sent by a correspondent node through red light, and the baseband processor 147 may be further configured to analyze the flag bit information and control the on states of the first amplifier 143 and the second amplifier 144 according to the flag bit information.
It should be noted that, since the third amplifier 145 connected to the third photodiode 1413 is a main receiving channel and is in a default on state, the communication device 100 of the electronic device can acquire the flag information sent by the opposite communication terminal through the red light at any time, and the baseband processor 147 can analyze and process the acquired flag information to determine whether to turn on the first amplifier 143 and the second amplifier 144. For example, when the flag bit information corresponding to the first amplifier is determined to be "1", the on state of the first amplifier 143 is set to on; when the flag bit information corresponding to the first amplifier is determined to be '0', the on state of the first amplifier 143 is set to be off; the second amplifier 144 is controlled in the same manner as the first amplifier 143.
Further, the communication device 100 of the electronic device in 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. 10, on the basis of the embodiment shown in fig. 9, the LiFi component 140 may further include: the plurality of emitters 148, wherein the plurality of emitters 148, may be a blue emitter 1481, a green emitter 1482, and a red emitter 1483.
Among other things, baseband processor 147 may also be used to control blue light emitter 1481, green light emitter 1482, and red light emitter 1483.
It should be noted that a blue light emitter 1481, a green light emitter 1482, and a red light emitter 1483 may be connected to the baseband processor 147, so that each emitter may send a LiFi signal according to the control instruction of the baseband processor 147. The blue light emitter 1481 may emit blue light as a carrier of the LiFi signal, the green light emitter 1482 may emit green light as a carrier of the LiFi signal, and the red light emitter 1483 may emit red light as a carrier of the LiFi signal.
Further, as shown in fig. 11, on the basis of the above embodiments, 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 149, wherein the switch 149 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 plurality of transmitters 148 and the plurality of receivers 146 may share the baseband processor 147, so that the baseband processor 147 may be connected to the plurality of transmitters 148 and the plurality of receivers 146 through the switch 149, respectively, so as to connect the baseband processor 147 to the receivers 146 (i.e., switch to a receiving path) through the switch 149 when the electronic device receives the LiFi signal; when the electronics send a LiFi signal, the baseband processor 147 is connected to the plurality of transmitters 148 (i.e., switched to the transmit path) through the switch 149.
