The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The embodiments of the present application provide a light fidelity LIFI communication control method for an electronic device, which is directed to the technical problem that when LIFI communication is performed between electronic devices in related technologies, one-to-many LIFI communication cannot be achieved, and the method divides a communication cycle into N time periods, after a connection is established between a master electronic device and first to nth slave electronic devices, the master electronic device communicates with the first to nth slave electronic devices respectively in the first to nth time periods, and when the master electronic device communicates with the ith slave electronic device, other slave electronic devices are switched to a search discovery state, so that one-to-many LIFI communication is achieved on the basis that LIFI hardware does not need to be added.
The following describes a method for controlling an optical fidelity LiFi communication of an electronic device according to an embodiment of the present application with reference to fig. 1.
Fig. 1 is a flowchart illustrating a LiFi communication control method for an electronic device according to an embodiment of the present disclosure.
As shown in fig. 1, a method for controlling an optical fidelity LiFi communication of an electronic device according to an embodiment of the present application includes:
And 102, dividing a communication cycle into N time periods by the master electronic device, wherein the master electronic device communicates with the first to Nth slave electronic devices in the first to Nth time periods respectively, and when the master electronic device communicates with the ith slave electronic device, switching other slave electronic devices into a search discovery state.
Wherein i is a positive integer less than or equal to N.
Specifically, the LiFi communication control method for the electronic device according to the embodiment of the present application, hereinafter referred to as a communication control method for short, may be executed by the LiFi communication control device for the electronic device according to the embodiment of the present application, hereinafter referred to as a communication control device for short, so as to implement LiFi communication between the electronic device and a plurality of other electronic devices.
The electronic device may be any type of electronic device such as a smartphone, a tablet computer, and a wearable device, which is not limited in this application.
For clearly explaining the optical fidelity LiFi communication control method of the electronic device, first, a hardware implementation logic according to the optical fidelity LiFi communication control method of the embodiment of the present application is explained with reference to fig. 2.
As shown in fig. 2, because the LiFi communication works in the same infrared frequency band, in the Emitting system, the present application may use a Vertical Cavity Surface Emitting Laser (Vcsel) and a driving Driver, in the embodiment of the present application, the driving signal of the LiFi Emitting mode comes from the RF coaxial connector (RF switch in fig. 2) path shown in fig. 2.
In the LiFi communication, optical information is received mainly by an avalanche diode (APD shown in fig. 2), and the APD converts the received optical signal into an electric signal and needs to further perform amplification processing in an operational Amplifier (Amplifier in fig. 2).
Thus, in the present example, the entire LiFi module consists of three parts. The first part is an application processor and a WiFi chip part and is used for providing radio frequency signals. The second part is the radio frequency to baseband signal part where the 2.4Ghz or 5Ghz radio frequency signal connected to the antenna is frequency converted to baseband by a mixer, after which the signal is separated into receive and transmit paths. The third part is a part that baseband electric signals are converted into optical signals through an optical front-end module, the signals are used for driving an infrared transmitter, such as a Vcsel device in the embodiment of the application, on the side of a transmitting path, light is received by a photodiode, and then the light is amplified through low noise and is turned to a radio frequency baseband interface.
According to the hardware basis based on the application, in order to realize one-to-many communication between the master electronic device and other slave electronic devices, three parts of assemblies need to be configured in the master electronic device, the first part is an application processor and a WiFi chip part and is used for providing radio frequency signals, the second part is used for converting radio frequency into baseband, and the third part is used for converting baseband electric signals into optical signals.
Therefore, in the embodiment of the present application, the main electronic device may include: the device comprises a LiFi communication assembly, a wireless fidelity WiFi/LiFi converter and a WiFi chip.
Wherein, the WiFi/LiFi converter is used for converting the LiFi signal into the WiFi signal.
The WiFi chip is used for processing the WiFi signals.
And the LiFi communication assembly is used for converting the optical signal into a LiFi electric signal or converting the LiFi electric signal into the optical signal.
It can be understood that when the main electronic device is used as a receiving end of the LiFi communication, the LiFi communication assembly can receive the optical signal and convert the optical signal into the LiFi electrical signal, and then the WiFi/LiFi converter can convert the LiFi electrical signal into the WiFi signal, so that the WiFi chip processes the WiFi signal; when main electronic equipment was as the transmission end of liFi communication, the data that will transmit can be handled to the wiFi chip, obtain the wiFi signal, then wiFi/liFi converter can be with wiFi signal conversion LiFi signal of telecommunication to convert the light signal into and send away through liFi communication assembly with the liFi signal of telecommunication. Therefore, the WiFi chip is used for processing the WiFi signals converted by the wireless fidelity WiFi/LiFi converter, and LiFi communication can be achieved.
Based on the hardware basis, in the embodiment of the application, the connection established between the master electronic device and the first to nth slave electronic devices is WiFi direct connection.
It can be understood that, on the basis of the above hardware, considering that the communication scheme is performed based on WiFi direct connection, the number of the connected devices can only be 1, and therefore, in order to implement one-to-many communication, a WiFi direct connection communication mechanism needs to be reasonably utilized.
In a specific implementation, the states after the master electronic device establishes connections with the first to nth slave electronic devices may be divided into a communication state and a search discovery state. When the two electronic devices are in a communication state, the two electronic devices are in a normal connection state and can perform data transmission; when the two electronic devices are in the search discovery state, the two electronic devices are in a state of being discoverable by each other.
In this embodiment, since the master electronic device can only be connected to one slave electronic device at the same time, in this embodiment, the master electronic device may be configured to divide the communication cycle into N time periods, the master electronic device communicates with the first to nth slave electronic devices in the first to nth time periods, respectively, and when the master electronic device communicates with the ith slave electronic device, the other slave electronic devices are switched to a search discovery state, where i is a positive integer less than or equal to N, so that after the master electronic device establishes a connection with the first to nth slave electronic devices, the master electronic device continuously switches the connection state with each slave electronic device, so as to implement LiFi communication between the master electronic device and the N slave electronic devices.
Taking fig. 3 as an example, assuming that N is 2, that is, the master electronic device needs to perform LiFi communication with two slave electronic devices at the same time, assuming that the two slave electronic devices are device 1 and device 2, the communication cycle may be divided into two time periods (T1 and T2 in fig. 3), after entering the T1 time period, the master electronic device starts to communicate with device 1 quickly, at this time, device 2 switches to the search discovery state, after entering the T2 time period, the master electronic device starts to communicate with device 2 quickly, at this time, device 1 switches to the search discovery state.
Therefore, LiFi communication between the master electronic device and the plurality of slave electronic devices can be realized without increasing hardware.
It can be understood that, because the master electronic device continuously switches the connection states with the N slave electronic devices when performing LIFI communication with the N slave electronic devices, in one communication cycle, there may be a case where data transmission between the master electronic device and a certain slave electronic device is not completed, and with reference to fig. 4, the communication control method provided in this embodiment of the present application is further described below.
Fig. 4 is a flowchart illustrating a LiFi communication control method for an electronic device according to another embodiment of the present disclosure.
As shown in fig. 4, the communication control method provided in the embodiment of the present application may further include:
and step 202, if not, recording the data transmission state, so that the master electronic device and the ith slave electronic device continue to perform data transmission according to the data transmission state in the ith time period of the next communication cycle.
Specifically, since the ith slave electronic device communicates with the master electronic device in the ith time period in each communication cycle, if data transmission between the master electronic device and the ith slave electronic device is not completed in the ith time period of the current communication cycle, the state of the data transmission, for example, how much data has been transmitted, how much data is not transmitted, or to which position of the file the data is transmitted, may be recorded, so that when the master electronic device and the ith slave electronic device switch to the communication state again in the ith time period of the next communication cycle, data transmission is continued according to the recorded data transmission state. Therefore, the breakpoint continuous transmission function of the data is realized.
It will be appreciated that normally, when the master electronic device communicates with the ith slave electronic device, the other slave electronic devices are in the search for discovery state, so that at the end of the ith time period, it is possible to switch to the other slave electronic devices being in communication with the master electronic device. In practical applications, in the process of communicating between the master electronic device and the ith electronic device, a situation that a search of a slave electronic device to be switched to a communication state next finds that the state is abnormal may occur, so that the slave electronic device cannot be switched to be in the communication state with the master electronic device. In the embodiment of the present application, when the master electronic device communicates with the ith slave electronic device, it may be determined whether the search discovery state of the other slave electronic devices is abnormal, so as to determine whether to switch the connection state according to the determination result.
That is, in this embodiment of the present application, the communication control method may further include:
when the master electronic device communicates with the ith slave electronic device, judging whether the search discovery states of other slave electronic devices are abnormal;
if yes, the master electronic device continues to communicate with the ith slave electronic device in the (i + 1) th time period.
Here, the other slave electronic device may refer to a slave electronic device to be switched into a communication state with the master electronic device.
Specifically, if it is not easy to search for the other slave electronic device from the master electronic device, or if it is not possible to search for the other slave electronic device, it may be considered that the search finding state of the other slave electronic device is abnormal.
In a specific implementation, when the master electronic device communicates with the ith slave electronic device, if the search of other slave electronic devices finds that the state is abnormal, the slave electronic device communicating with the master electronic device may not be switched, that is, the master electronic device may be continuously controlled to communicate with the ith slave electronic device in the (i + 1) th time period.
It can be understood that, when the search discovery state of the other slave electronic devices is abnormal, in order to avoid that the communication time between the master electronic device and the ith slave electronic device is too long, and the other slave electronic devices cannot communicate with the master electronic device, in this embodiment of the present application, a communication cycle of the master electronic device and the ith slave electronic device in continuous communication may be recorded, and a communication cycle threshold n may be set, and then the communication cycle of the master electronic device and the ith slave electronic device in continuous communication may be compared with the communication cycle threshold n, and if the communication cycle of the master electronic device and the ith slave electronic device in continuous communication does not reach the communication cycle threshold n, for example, n-1, and it is detected that the search discovery state of the other slave electronic devices returns to normal, the master electronic device may be switched to communicate with the other slave electronic devices, and after the master electronic device and the slave electronic devices continuously communicate for n-1 communication cycles, and then switching the slave electronic device which communicates with the master electronic device.
If the communication cycle of the continuous communication between the master electronic device and the ith slave electronic device reaches the communication cycle threshold n and the search discovery state of other slave electronic devices is detected not to be recovered to normal, the user can be prompted to search for the slave electronic device with the abnormal state to be in the abnormal connection state, so that the user can adjust the abnormal slave electronic device.
It is understood that when the master electronic device communicates with the ith slave electronic device, the communication state of the master electronic device and the ith slave electronic device may also be abnormal, for example, the communication between the master electronic device and the ith slave electronic device is difficult, and in the embodiment of the present application, when the master electronic device communicates with the ith slave electronic device, if it is determined that the communication state of the master electronic device and the ith slave electronic device is abnormal, the master electronic device may be immediately switched to communicate with other slave electronic devices.
For example, continuing with the example shown in fig. 3, assuming that T1+ T2 is a communication cycle, the communication cycle threshold is n, and when the T1 time period ends, the main electronic device needs to switch to communicate with the device 2, however, in the T1 time period, it is detected that the main electronic device and the device 2 cannot search for the other party, the communication object of the main electronic device may not be switched, and the main electronic device and the device 1 may continue to be controlled to communicate in the T2 time period. If the search discovery state of the device 2 is detected to be recovered to normal in n communication cycles, and at this time, the device 1 and the main electronic device continuously communicate for n-2 communication cycles, the main electronic device and the device 2 may be switched to communicate, and the main electronic device and the device 2 are controlled to continuously communicate for n-2 communication cycles. If it is detected that the master electronic device is difficult to communicate with device 1 within the time period T1, it may be possible to immediately switch to the master electronic device to communicate with device 2 and update the cycle schedule.
In an exemplary embodiment, after the master electronic device and the N slave electronic devices are all connected, the communication control apparatus may detect, in real time, a data transmission state between the master electronic device and the first to nth slave electronic devices, and if one of the slave electronic devices has completed data transmission with the master electronic device, may not perform cycle detection, that is, may not switch to communication between the slave electronic device and the master electronic device until the slave electronic device adds a transmission task again, and then restart cycle switching.
In an exemplary embodiment, in order to make the user know which slave electronic device the master electronic device is currently communicating with, and the magnitude of the data transmission speed, in the embodiment of the present application, the connection state and the transmission speed of the master electronic device and the first to nth slave electronic devices may also be displayed on the master electronic device. Of course, the connection state between the slave electronic device and the master electronic device and the data transmission rate when the slave electronic device and the master electronic device are in the communication state may also be displayed in the slave electronic device, which is not limited in this application.
It should be noted that the connection state herein may include not only a communication state and a search discovery state after the connection between the master electronic device and a certain slave electronic device is established, but also whether a connection state is established. In the embodiment of the present application, the refresh period of the connection states of the master electronic device and the first to nth slave electronic devices may be set to be one communication period, that is, the connection states of the master electronic device and the first to nth slave electronic devices displayed on the master electronic device or the slave electronic devices are not changed in one communication period. For example, assuming that the example shown in fig. 3 is continuously used, in one communication cycle, since the device 1 and the device 2 have established connection, it may be displayed in the main electronic device that the connection states with the device 1 and the device 2 are both connected. In addition, the data transmission rate between the master electronic device and a certain slave electronic device may be a data transmission rate in one communication cycle, or may also be a data transmission rate in other time periods, which is not limited in this application.
