Fig. 1 is a flowchart illustrating an optical fidelity LiFi communication control method of a mobile terminal according to an embodiment of the present application.
It should be noted that the optical fidelity LiFi communication control method for the mobile terminal provided in the embodiment of the present application is applied to a mobile terminal having a LiFi communicator, the mobile terminal communicates with other devices through the LiFi communicator, because the bottom layer of the Li-Fi protocol is compatible with the WiFi802.11 baseband, when transmitting data, a TDD protocol in WiFi can be used to achieve one-to-many or many-to-one simultaneous transmission, and the Li-Fi technology has very high security when transmitting data, because visible light can only be transmitted along a straight line, and has good directivity, only a person on the light transmission straight line can capture information, thereby using the LiFi technology to perform communication, and improving the security of data transmission. In addition, because the optical communication mode is adopted to transmit data, the frequency band is not limited, so that the interference is avoided, and the reliability of data transmission is ensured. And because the low time delay of LiFi, can be applied to the scene that needs the data of quick transmission, for example share the file fast, exchange business card contact means, watch video jointly etc..
As shown in fig. 1, the optical fidelity LiFi communication control method of the mobile terminal of the present application may include the following steps:
Specifically, the LiFi communication control method for mobile terminals according to the embodiments of the present application may be implemented by the LiFi communication control device for mobile terminals according to the embodiments of the present application, which is hereinafter referred to as a communication control device for short. Wherein the communication control means may be configured in the first mobile terminal to display the pointer in the first mobile terminal after generating the rotation angle of the pointer. The first mobile terminal and the second mobile terminal in the embodiment of the present application may be any hardware device capable of performing LiFi communication by using the LiFi communicator included in the first mobile terminal and the second mobile terminal, such as a smart phone, a tablet computer, a personal digital assistant, and the like. The first mobile terminal and the second mobile terminal are taken as smart phones for illustration.
In an exemplary embodiment, when the first mobile terminal performs LiFi communication with the second mobile terminal, the first mobile terminal may serve as a light emitting end, and the second mobile terminal may serve as a light receiving end. At this time, the LiFi communicator in the first mobile terminal may include an LED array. The LED array can emit visible light and can also work in an infrared frequency band, so that the data transmission distance of other equipment during LiFi communication is increased, and the LED array is not limited by the application. In addition, the first mobile terminal may further include a first LiFi transmission module therein. Accordingly, the second mobile terminal may include a Photo Diode (PD) receiver and a second LiFi transmission module. When carrying out the liFi communication, first liFi transmission module can treat that the transmission data encode in order to form the coded data to send away the coded data through the LED array, after the PD receiver of second mobile terminal received the coded data, second liFi transmission module can decode the coded data that the PD receiver received, thereby acquires the transmission data, realizes first mobile terminal and second mobile terminal's communication.
In an exemplary embodiment, when the first mobile terminal performs LiFi communication with the second mobile terminal, the first mobile terminal may also serve as a light receiving end, and the second mobile terminal serves as a light emitting end. At this time, the LiFi communicator in the first mobile terminal may include a PD receiver. The PD receiver can receive visible light and can also work in an infrared frequency band, so that the data transmission distance of LiFi communication with other equipment is increased, and the PD receiver is not limited by the application. In addition, a third LiFi transmission module may be further included in the first mobile terminal. Accordingly, the second mobile terminal may include an LED array and a fourth LiFi transfer module. When carrying out the liFi communication, fourth liFi transmission module can treat that the transmission data encode in order to form the coded data to send away the coded data through the LED array, after first mobile terminal's PD receiver received the coded data, third liFi transmission module can decode the coded data that the PD receiver received, thereby acquires the transmission data, realizes first mobile terminal and second mobile terminal's communication.
It should be noted that, when the first mobile terminal and the second mobile terminal establish the LiFi connection, the two parties may handshake first, and then data transmission is performed by the light emitting ends in the first mobile terminal and the second mobile terminal, and the light receiving end replies the confirmation information after receiving the confirmation information, and if the light receiving end does not receive data within a certain time, the light emitting end may generate an overtime signal by itself and retransmit the data, so as to ensure that the light receiving end can receive the data.
Specifically, the communication control device may acquire the first location of the first mobile terminal in any location-enabled manner, such as a Global Positioning System (GPS) or a network System in the first mobile terminal.
In addition, a phased antenna may be installed in the first mobile terminal such that beam scanning is performed by the phased array antenna to acquire the second location of the second mobile terminal. Alternatively, the communication control device may acquire the second location of the second mobile terminal in other manners, which is not limited in this application.
And 103, generating a relative angle of the second mobile terminal relative to the first mobile terminal according to the first position and the second position.
Specifically, the relative direction between the second mobile terminal and the first mobile terminal can be determined through the acquired first position of the first mobile terminal and the acquired second position of the second mobile terminal, and a reference direction is determined, so that the angle of the included angle between the relative direction and the reference direction is used as the relative angle of the second mobile terminal relative to the first mobile terminal.
In an exemplary embodiment, taking the first mobile terminal as the light emitting end as an example, the reference direction is related to the setting position of the LiFi communicator, the light emitting angle, and other factors. As shown in fig. 2, assuming that the LiFi communicator of the first mobile terminal is disposed at the top of the first mobile terminal and the light emission angle is B, a direction right at the light emission angle, i.e., a direction (a direction) perpendicular to the line direction (B direction) of the top of the housing of the first mobile terminal may be set as a reference direction.
In a specific implementation, the relative angle of the second mobile terminal with respect to the first mobile terminal may be generated in the following manner.
And 103a, acquiring the orientation of the first mobile terminal according to the geomagnetic sensor of the first mobile terminal.
And 103b, generating a relative angle of the second mobile terminal relative to the first mobile terminal according to the orientation, the first position and the second position of the first mobile terminal.
In an exemplary embodiment, the orientation of the first mobile terminal may be obtained through a geomagnetic sensor of the first mobile terminal, or may also be obtained through other manners, which is not limited in this application.
For example, as shown in fig. 3, assuming that a direction (a direction) perpendicular to a line direction (dotted line direction) along the top of the housing of the first mobile terminal is set as a reference direction, when the direction of the first mobile terminal is as shown in fig. 3, if it is determined that a relative direction of the second mobile terminal and the first mobile terminal is a C direction according to the first position of the first mobile terminal and the second position of the second mobile terminal, an included angle a between the C direction and the a direction is a relative angle of the second mobile terminal with respect to the first mobile terminal.
And 104, generating a rotation angle of the pointer according to the relative angle of the second mobile terminal relative to the first mobile terminal.
It can be understood that, in the embodiment of the present application, after the first mobile terminal and the second mobile terminal establish the LiFi connection, a pointer may be displayed on a display interface of the first mobile terminal, a rotation angle of the pointer may represent a relative angle of the second mobile terminal with respect to the first mobile terminal, and a pointing direction of the pointer may represent a direction of the second mobile terminal with respect to the first mobile terminal, so that a user may adjust a placement manner of the first mobile terminal according to the pointer displayed in the first mobile terminal, so that the first mobile terminal and the second mobile terminal are aligned to perform the LiFi communication.
The relative angle of the second mobile terminal relative to the first mobile terminal is the rotation angle of the pointer. The direction of the second mobile terminal relative to the first mobile terminal is the pointing direction of the pointer.
It should be noted that, in this embodiment of the application, when the first mobile terminal and the second mobile terminal establish a LiFi connection, the second mobile terminal may also perform the same operation as the first mobile terminal, so that a pointer similar to that in the first mobile terminal may also be displayed in the second mobile terminal, so as to enable a user to which the second mobile terminal belongs to adjust a placement manner of the second mobile terminal according to the pointer displayed in the second mobile terminal, so that the second mobile terminal and the first mobile terminal are aligned to perform LiFi communication.
In practical application, the pointers displayed in the first mobile terminal and the second mobile terminal can be changed in real time according to the first position and the second position of the first mobile terminal and the second mobile terminal, the position of any one mobile terminal or the direction of the any one mobile terminal relative to the other mobile terminal is changed, and the pointer displayed in the other mobile terminal can also be changed in real time, so that users of both communication parties can adjust the placing position of the mobile terminal in real time according to the display of the pointer.
For example, assuming that the positions of the mobile terminal a and the mobile terminal B are shown in fig. 4 and 5, the orientations of the mobile terminal a and the mobile terminal B are parallel to each other, the relative angle of the mobile terminal B with respect to the mobile terminal a is a, and the relative angle of the mobile terminal a with respect to the mobile terminal B is also a, the pointers shown in fig. 4 may be displayed in both the mobile terminal a and the mobile terminal B. The rotation angle of the pointer displayed in the mobile terminal a is a, the direction of the pointer points to the direction of the mobile terminal B relative to the mobile terminal a, the rotation angle of the pointer displayed in the mobile terminal B is a, and the direction of the pointer points to the direction of the mobile terminal a relative to the mobile terminal B. When the mobile terminal a and the mobile terminal B are adjusted to face the directions indicated by the dotted arrows as shown in the right side of fig. 5, respectively, the mobile terminal a and the mobile terminal B are aligned, and the energy loss of light is minimized and the data transmission rate is fastest when the LiFi communication is performed in this direction.
In fig. 4, the dotted arrow indicates a standard position, i.e., a pointer position when the mobile terminal a is aligned with the mobile terminal B, corresponding to the reference direction mentioned earlier in the present application, and the solid arrow indicates a current pointer position. When the solid arrow coincides with the dashed arrow position, it indicates that mobile terminal a is currently aligned with mobile terminal B. Taking the pointer displayed in the mobile terminal a as an example, when the solid line arrow is shifted from the direction of the dotted line arrow, it indicates that the mobile terminal a is currently shifted from the alignment direction.
Note that, in the case shown in fig. 4, the mobile terminal a and the mobile terminal B are oriented parallel to each other, and in this case, the pointers displayed on the mobile terminal a and the mobile terminal B are both located on the left side of the standard position and have a size. When the orientations of the mobile terminal a and the mobile terminal B are not parallel to each other, the rotation angles and the directions of the pointers displayed in the two mobile terminals may be different.
Further, in order to ensure accuracy of the direction and angle information displayed by the pointer in the first mobile terminal, in this embodiment of the application, the second mobile terminal may further obtain a third position of the first mobile terminal and a fourth position of the second mobile terminal, and send the third position and the fourth position to the communication control device of the first mobile terminal, so that the communication control device of the first mobile terminal may compare the first position obtained by the communication control device with the third position obtained by the second mobile terminal, and compare the second position obtained by the communication control device with the fourth position obtained by the second mobile terminal. If the communication control device of the first mobile terminal determines that the difference value between the first position and the third position and the difference value between the second position and the fourth position are both within the preset difference value range, the first position and the second position can be determined to be accurate, and then follow-up operation is executed according to the first position and the second position.
In addition, in order to ensure the accuracy of the direction and angle information displayed by the pointer in the second mobile terminal, the first mobile terminal may also send the first position and the second position acquired by the first mobile terminal to the second mobile terminal, so that the second mobile terminal can determine whether the third position of the first mobile terminal and the fourth position of the second mobile terminal acquired by the second mobile terminal are accurate according to the first position and the second position, and then perform subsequent operations when the third position and the fourth position are accurate.
Further, in order to enable the user to know more information through the display interface of the first mobile terminal, in the embodiment of the present application, other information related to the LiFi communication may also be displayed. For example, in the embodiment of the present application, the distance between the second mobile terminal and the first mobile terminal may be detected, so that the distance is displayed in the first mobile terminal as shown in fig. 4. In addition, it is also possible to detect an information transmission speed between the second mobile terminal and the first mobile terminal, thereby displaying the information transmission speed in the first mobile terminal. In addition, information such as optical signal intensity during LiFi communication may be displayed, which is not limited in the present application.
Specifically, the distance between the first mobile terminal and the second mobile terminal can be detected by a distance sensor in the first mobile terminal by using the principle of the "time-of-flight method". Or after the first mobile terminal and the second mobile terminal establish the LiFi connection, the signal intensity of the light signal sent by the second mobile terminal may be detected, and the decrease in the light signal intensity may be caused by the increase in the distance, so that the distance between the first mobile terminal and the second mobile terminal may be determined according to the light signal intensity. Alternatively, the distance between the first mobile terminal and the second mobile terminal may be detected in other manners, which is not limited in this application.
The LiFi communication control method of the mobile terminal, provided by the embodiment of the application, includes the steps of firstly establishing LiFi connection between a first mobile terminal and a second mobile terminal, then obtaining a first position and a second position of the first mobile terminal and the second mobile terminal, then generating a relative angle of the second mobile terminal relative to the first mobile terminal according to the first position and the second position, further generating a rotation angle of a pointer according to the relative angle of the second mobile terminal relative to the first mobile terminal, and finally displaying the pointer in the first mobile terminal. Therefore, the rotation angle of the pointer is automatically generated according to the positions of the two communication parties and displayed in the mobile terminal, so that a user can adjust the placing position of the mobile terminal according to the rotation angle of the pointer displayed in the mobile terminal, and then the mobile terminal is aligned with the opposite communication party to carry out LiFi communication.
