All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes in detail a file transfer method and apparatus provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
The file transmission method provided by the embodiment of the application can be applied to first electronic equipment, and the first electronic equipment can perform visible Light wireless communication (Light Fidelity, LiFi).
Visible light wireless communication can also be called as a LiFi technology, and visible light spectrum can be utilized for wireless data transmission based on the LiFi technology.
As shown in fig. 1, a file transmission method provided in an embodiment of the present application includes:
and 103, transmitting the target file to the second electronic equipment based on the LiFi connection.
In this embodiment, the target file may be a video, picture, or document type file, and is not limited in detail here.
In combination with some application scenarios, in the case that a file selection interface is displayed in the first electronic device, the user may select a file to be transmitted in the file selection interface.
For example, a gallery interface may be displayed in the first electronic device, and a user may select a thumbnail of a picture in the gallery interface. For another example, information of a plurality of documents may be displayed in the document management interface in the first electronic device, and the user may select a document in the document management interface.
The above gallery interface on which thumbnails are displayed or the document management interface on which document information is displayed may be regarded as a file selection interface. And the picture or document selected by the user can be regarded as the target file.
In the event that a user selection input to a target file is received, the first electronic device may transmit a first light signal in response to the selection input. In other words, in step 101, the first electronic device may transmit the first optical signal in response to an input selecting the target file.
For example, when a selection input of the user to the target file is received, the first electronic device may control a display screen, a Light Emitting Diode (LED) breathing lamp, an LED Light supplement lamp, or other Light Emitting units to be turned on and off according to a preset frequency in response to the selection input, so as to implement sending of the first optical signal.
In other words, the first light signal may be a blinking light signal. Similarly, the second optical signal and the optical signal for transmitting the target document may be a flashing optical signal.
For example, the first electronic device may include a first display screen, and the first display screen may be an LED display screen. The first optical signal can be sent by controlling all or part of the LED modules in the LED display screen to be on or off according to preset frequency.
Of course, only some examples of the first display screen are given here, and in practical applications, the first display screen may also be an Organic Light-Emitting Diode (OLED) display screen or other types of display screens, and the first display screen is not limited in detail here, and can transmit the optical signal.
The first optical signal transmitted by the first electronic device may be received by the second electronic device. For example, the second electronic device may be a mobile terminal or a personal computer integrated with a LiFi signal receiver, and is not limited herein.
For example, the second electronic device may be of a similar configuration to the first electronic device, i.e., the second electronic device may include a light emitting unit that can be turned on and off at a preset frequency. Meanwhile, the second electronic device may also include a LiFi signal receiver for receiving a LiFi signal. As such, the second electronic device may not only receive the first optical signal, but also transmit the second optical signal through the light emitting unit in response to the first optical signal.
For another example, the second electronic device may include a second display screen, and the LiFi signal receiver of the second electronic device may be disposed on a side (hereinafter referred to as a front side) of the second display screen of the second electronic device. In the case of the second electronic device facing the first electronic device, on the one hand, the first optical signal can be received by a LiFi signal receiver; on the other hand, the second light signal may be transmitted by flashing the second display screen.
Of course, in practical applications, the second electronic device is not limited to the structure exemplified above. For example, the second electronic device may have a LiFi signal receiver and a LiFi signal transmitter, and may be capable of transmitting and receiving a LiFi signal without including a second display screen.
Alternatively, the second electronic device may include a second display screen, but the second display screen may not be controlled to flash to transmit the LiFi signal, and the like, but the second display screen may be controlled to flash to transmit the LiFi signal through an LED breathing lamp or an LED fill-in lamp.
In general, the second electronic device may be capable of receiving and transmitting the LiFi signal, and the specific receiving and transmitting manner is not limited herein.
In step 102, the first electronic device may receive a second optical signal transmitted by the second electronic device, so as to establish a LiFi connection with the second electronic device.
For example, the first optical signal may be information broadcasted for requesting establishment of the LiFi connection. The second electronic device, upon receiving the first light signal, may send a second light signal in response to the first light signal to agree to establish a LiFi connection with the first electronic device.
The first electronic device may establish a LiFi connection with the second electronic device after receiving the second optical signal.
On the basis, the first electronic device and the second electronic device can transmit files through the LiFi connection. Specifically, in this embodiment, the first electronic device may transmit the object file to the second electronic device based on the LiFi connection.
It is easy to understand that, in the process of transmitting the object file to the second electronic device by the first electronic device based on the LiFi connection, the object file may be transmitted by a flashing light signal with a preset frequency through a change of on and off of a light emitting unit such as the first display screen, the LED breathing lamp, or the LED fill-in lamp.
In the process of transmitting the target file based on LiFi connection, the transmission of the target file can be maintained through the flashing light signal sent by the first electronic device, the process can not be influenced by factors such as network signals and the like, and the reliability of the file transmission process can be effectively ensured.
In the file transfer method provided by the embodiment of the application, the first electronic device sends the first optical signal in response to the selected target file, and establishes the LiFi connection with the second electronic device when receiving the second optical signal sent by the second electronic device in response to the first optical signal, and based on the LiFi connection, the first electronic device can transfer the target file to the second electronic device. According to the embodiment of the application, the files are transmitted through LiFi connection, the file transmission process can not be limited by network signals, and the reliability of the file transmission process is effectively improved.
In addition, the target file can be selected in advance by a user, after the LiFi connection is established between the first electronic device and the second electronic device, the user does not need to further input related target file selection on the first display screen, the interruption of LiFi connection caused by the fact that the user blocks light signals for too long time is effectively avoided, and therefore the stability and the reliability of the LiFi connection are effectively improved.
In one embodiment, a first electronic device includes a first display screen and a LiFi chip;
accordingly, in response to an input selecting a target file, sending a first optical signal may specifically include:
and responding to the input of selecting the target file, and controlling the first display screen to send a first light signal through the LiFi chip.
In this embodiment, the LiFi chip can be electrically connected with the first display screen, and can control the first display screen to light and go out according to the preset frequency in order to send optical signal, and then realize the data wireless transmission between first electronic equipment and other electronic equipment.
Specifically, the first electronic device may control the first display screen to transmit the first light signal through the LiFi chip.
The first light signal obtained by the first display screen being turned on and off according to the preset frequency may be a relatively high-speed flashing light signal. In general, the flicker of the first light signal is relatively difficult to be perceived by human eyes, and thus, the first light signal may be transmitted without affecting the user or with less effect on the vision of the user.
Similarly, in the process of transferring the target file, the flashing light signal for transferring the target file does not influence the normal use of the first display screen by the user.
In one example, the LiFi chip can electrically connect all or a portion of the LED modules in the LED display screen. The LiFi chip can control the LED module connected with the LiFi chip to flicker through an electric signal, and therefore a first light signal is sent.
Furthermore, it is easy to understand that, for the LiFi chip, in addition to controlling the first display screen to turn on and off to obtain the light signal, the first display screen can also be used for processing the received light signal.
For example, the received second optical signal may be processed by a LiFi chip. In the event that the LiFi chip determines that the second light signal is generated by the second electronic device in response to the first light signal, the first electronic device may establish a LiFi connection with the second electronic device.
In order to simplify the description, in the following embodiments, the first electronic device will be mainly described as an example of sending the optical signal by controlling the first display screen to be turned on or off.
In one example, the second electronic device may prompt the user through the second display screen or the audible and visual prompting device in response to the first light signal when receiving the first light signal. In case an input indicating agreement to establish a LiFi connection is received, a second light signal is further sent.
In another example, the second electronic device may also directly transmit the second optical signal in case of receiving the first optical signal, so that the first electronic device can obtain information of devices with which the LiFi connection can be currently established.
In other words, the first optical signal may be self-identity information broadcasted by the first electronic device and status information of the first electronic device that the LiFi connection can be performed. Generally, information exchanged for the LiFi communication is carried by an optical signal, and thus, information of a device with which the first electronic device can perform the LiFi communication is acquired. The second electronic device may transmit a second light signal to the first electronic device in response to the first light signal after receiving the first light signal to inform the first electronic device that the LiFi communication is possible therewith.
And the process that the second electronic device receives the input of the user to agree to the target file transmission can also be carried out in the subsequent interactive process. This interaction process can be explained in detail in the following examples of embodiments.
Generally, the first electronic device determines an object file to be transmitted, and transmits the object file when the second electronic device establishes the LiFi connection.
In some application scenarios, the transmission process of the target file may require a longer transmission time, and the relative position between the first electronic device and the second electronic device is changed more, which may result in a poor stability of the transmission process.
In order to facilitate the user to transmit the target file through the LiFi connection in a suitable operation state and ensure the stability of the target file transmission process, in an embodiment, the step 103 of transmitting the target file to the second electronic device based on the LiFi connection includes:
receiving a first input;
in response to the first input, the target file is transmitted to the second electronic device based on the LiFi connection.
In combination with an example of an application scenario, the first electronic device includes a first display screen, and the second electronic device includes a second display screen. The first electronic device and the second electronic device may be LiFi connections which are arranged opposite to each other on the display screen and are established in a bright screen state.
Specifically, in the example of the application scenario, the first electronic device sends the light signal by controlling the first display screen to blink, and may receive the light signal sent by the second electronic device through the LiFi signal receiver disposed on the front side. The second electronic device may also implement the process of transceiving optical signals as shown by the first electronic device.
When the first electronic device and the second electronic device are in a state that the display screens are oppositely arranged, interaction of optical signals can be carried out between the first electronic device and the second electronic device. And the light signal may be generated when the display screen is in a bright state. Therefore, from a visual point of view, the first electronic device and the second electronic device may be a LiFi connection established in a state where the display screen is bright.
At this time, in order to simplify the input operation of the user, the first input may correspond to a tapping operation of the back case of the first electronic device by the user, a shaking operation of the first electronic device, or the like.
For example, in a case where the first electronic device is bright opposite to the second electronic device, the user may double-click on the back shell of the first electronic device, and the first electronic device may detect a first input of the double-click on the back shell through the acceleration sensor and may start to transmit the target file to the second electronic device in response to the first input.
Or, the user may shake the first electronic device, where the LiFi connection is usually wireless communication based on visible light, and shaking the first electronic device within a certain range may ensure that the emitted light signal can be continuously received by the second electronic device.
And the first electronic device may detect a shaking input of the user through the acceleration sensor and start to transmit the target file to the second electronic device in response to the shaking input.
Therefore, in the operation process corresponding to the first input, the user does not need to stretch fingers or other operation components between the first electronic device and the second electronic device, the shielding of visible light for LiFi communication is caused, and the connection stability of LiFi is ensured.
In addition, in combination with other application scenarios, a user may place the second electronic device at a position such as a desk and hold the first electronic device while sending the target file to the second electronic device through the first electronic device. Under the condition that the relative positions of the electronic devices are stable and the user is in a proper operation posture on the electronic devices, the first input is performed on the first electronic device to transmit the target file, so that the user does not need to adjust the posture of holding the first electronic device too much in the transmission process of the target file.
Of course, the corresponding posture and position relationship when the first electronic device and the second electronic device maintain the LiFi connection are just some examples. In practical applications, the posture, the position relationship, and the like between the first electronic device and the second electronic device can be determined according to the installation position of the LiFi signal transceiver on the second electronic device.
The first input may be an input on the first display screen. For example, in the case where the first electronic device establishes the LiFi connection with the second electronic device, a corresponding operation control, such as an icon control named "start transmission" or the like, may be displayed in the first display screen. And under the condition that first input in the modes of clicking input and the like of the operation control by the user is received, the target file can be transmitted to the second electronic equipment through LiFi connection.
In one embodiment, when the first electronic device starts to transmit the target file to the second electronic device, at the second electronic device, a corresponding operation control, such as an icon control named "accept" or the like, may also be displayed on the second display screen. In the case where an input to the icon control of "accept", the second electronic device starts to receive and store the above-mentioned target file.
Of course, an icon control named "deny receipt" may also be displayed on the second electronic device. In the event that input is received to the "deny receipt" icon control, the second electronic device may not receive the target file described above.
In some application scenarios, through reasonable setting of the installation position of the LiFi signal receiver, when a user operates the first display screen or the second display screen, the situation that a finger and the like of the user blocks light signals is avoided as much as possible.
For example, the LiFi signal receiver may be disposed above the first display screen, and in general, when the user operates the icon control, the LiFi signal receiver may be prevented from being blocked.
Of course, generally speaking, when the first electronic device and the second electronic device are connected by the LiFi, the temporary blocking of the optical signal may be considered to be a decrease in intensity of the optical signal caused by a poor communication state to a certain extent, and the temporary blocking may not affect the overall transmission of the target file.
In other words, in a general case, the operation of the user on the first display screen or the second display screen may not affect or may less affect the reliability of the transmission process of the target file.
In order to improve the security of the target file transmission, in an embodiment, in step 103, before transmitting the target file to the second electronic device based on the LiFi connection, the file transmission method may further include:
acquiring encryption information of a target file and optical signal frequency adopted by LiFi connection;
transmitting the target file to the second electronic device based on the LiFi connection, comprising:
and transmitting the target file to the second electronic device based on the LiFi connection under the condition that the encrypted information is matched with the optical signal frequency.
In this embodiment, the target file may have corresponding encryption information, and the encryption information may be used to represent the encryption status or the encryption level of the target file. For example, the encryption status may refer to whether the target file is an encrypted file.
The encryption information of the target file may be preset or manually set by the user, and is not limited in detail here.
In one example, the encryption information of the target file may be automatically determined for the target file according to preset rules. For example, the target file may be a picture-type file, and when the first electronic device recognizes the target file as a certificate picture based on a picture recognition model, the encryption information of the target file may be indicated as an "encrypted file". And when the target file is recognized as a landscape picture, the encryption information of the target file may be indicated as an "unencrypted file".
In one example, the encryption information of the target file may be manually set by the user. For example, the target file may be a document type file. The user may manually set the encryption level of the target file. The encryption level may be set to "top secret", "secret", and "normal", etc., according to the degree of importance.
Of course, the above is merely a few examples of the encryption information of the target file, and in practical applications, the content indicated by the encryption information, or the specific determination manner, may be set as needed.
There may be a plurality of frequencies of the optical signal used by the first electronic device to transmit the target document. These frequencies may be preset.
For example, the first electronic device may transmit the target file through the optical signals of the first preset frequency and the second preset frequency.
It is easily understood that, in the present embodiment, the light signal frequency may refer to a frequency of the light signal, specifically, a flashing frequency of the light signal, or a lighting frequency of a lighting unit, such as the first display screen, for a user to send the light signal.
In addition, in this embodiment, a preset corresponding relationship may be established between the encrypted information of the target file and the optical signal frequency used for the connection of the first electronic device LiFi.
For example, the encrypted information includes an "encrypted file" or an "unencrypted file", and the preset correspondence may mean that the "unencrypted file" is transmitted by an optical signal with a first preset frequency, and the "encrypted file" is transmitted by an optical signal with a second preset frequency.
In this embodiment, before the first electronic device transmits the target file, the first electronic device may acquire the optical signal frequency used for connecting the encrypted information of the target file and the LiFi. And under the condition that the encryption information of the target file is matched with the frequency of the optical signal, the first electronic device transmits the target file to the second electronic device based on the LiFi connection.
Therefore, the transmission process of the target file can be limited through the optical signal frequency in the embodiment, that is, the target file is transmitted under the condition that the optical signal frequency is matched with the encryption information of the target file, and the transmission safety of the target file can be ensured to a certain extent.
Of course, in some possible embodiments, the optical signal frequency may also be an optical frequency. For example, different colors of light may have different frequencies. When different specific target files of the encrypted information are transmitted, light signals with different colors can be adopted.
In order to enable the first electronic device to transmit the target file with different encryption information, in one embodiment, before transmitting the target file to the second electronic device based on the LiFi connection, the file transmission method may include:
receiving a second input;
in response to the second input, the frequency of the optical signal used by the LiFi connection is changed.
In this embodiment, the second input may be a tap or shake input corresponding to the user on the first electronic device; or, the input can be voice, gesture and other types of input; alternatively, the input may be a click, a slide, or the like type input on the first display screen, and may not be particularly limited.
In general, the specific operation mode of the second input can be distinguished from the operation mode of the first input. For example, the first input may be a double-click backshell input, the second input may be a single-click backshell input, and so on.
In combination with an application scenario, under the condition that the target file cannot be normally transmitted, a user can knock the back shell of the first electronic device, so that the first electronic device changes the optical signal frequency adopted by the LiFi connection, and the target file with corresponding encrypted information can be transmitted conveniently.
In one example, there may be a correspondence between the manner of operation of the second input and the frequency of the optical signal. For example, when the user shakes the first electronic device in a left-right direction, the first electronic device may determine the frequency of the optical signal employed for the LiFi connection as a first preset frequency in response to the shaking operation. And when the user taps the back shell three times in succession, the first electronic device can respond to the operation of tapping three times, confirms the light signal frequency that the LiFi connects and adopts as the second preset frequency.
In another example, the second electronic device may also be a second input responsive to some preset mode of operation, for example, a single tap of the back shell, to switch the frequency of the optical signal. That is, the user can tap the back shell once, and the frequency of the optical signal can be switched once according to a specific sequence.
As can be seen from the above examples, by setting the specific operation mode corresponding to the second input of the frequency switching of the touch signal, the diversified operation habits of the user can be satisfied. Meanwhile, the specific operation mode corresponding to the second input can also be used as an unlocking mode for triggering the optical signal frequency, and the safety of target file transmission can be improved through setting the second input.
Optionally, in order to further improve the security of the target file transmission, the replacing, in response to the second input, the frequency of the optical signal used by the LiFi connection may specifically include:
acquiring biometric information in response to the second input;
and under the condition that the biological identification information is matched with the preset biological identification information, replacing the optical signal frequency adopted by the LiFi connection.
For example, the second input may be a touch input of the user to a fingerprint recognition module in the first electronic device, or an approach action in front of a camera with a palm print information or iris information collecting function, or the like.
As shown above, during the LiFi communication, the glistening light information is temporarily blocked, and the LiFi connection can still be maintained. Therefore, for the first electronic device with the camera for collecting the iris information positioned on the front side, the user can still turn the first electronic device to the face of the user, so that the first electronic device can collect the iris information.
It is easily understood that the first electronic device may be pre-stored with the biometric information of the user, i.e. the pre-set biometric information mentioned above. When the biometric information obtained by the first electronic device in response to the second input matches the preset biometric information, the frequency of the optical signal used for the LiFi connection can be changed.
Therefore, in the embodiment, the switching of the optical signal frequency for the LiFi communication is performed based on the biometric information, so that the encrypted file or the file with a higher encryption level can be effectively prevented from being acquired by an illegal user, and the security of the target file is improved.
As indicated above, the light signal has a high flicker frequency and is generally difficult to be recognized by the naked eye of the user. Therefore, in order to enable the user to know the change of the optical signal frequency adopted by the first electronic device, in one embodiment, after receiving the second input, the file transmission method may further include:
and responding to the second input, and replacing the color of the optical signal adopted by the LiFi connection, wherein the color of the optical signal is matched with the frequency of the optical signal adopted by the LiFi connection.
For example, the first electronic device transmits an optical signal through the first display screen to transmit the target file. Meanwhile, the first electronic device can realize the LiFi connection by adopting optical signals with two frequencies, namely a first preset frequency and a second preset frequency.
When the first electronic device uses the optical signal with the first preset frequency, the color of the first display screen can be displayed as red. And when a second input is received, so that the second electronic device adopts an optical signal with a second preset frequency, the color of the first display screen can be displayed as blue.
In other words, the first electronic device can cause the first display screen to emit light of a matching color when the LiFi connection is performed using one optical signal frequency.
Therefore, the user can intuitively know the frequency conversion of the optical signal adopted by the first electronic device, and the user is prevented from carrying out redundant operation on the first electronic device.
Of course, the above change of the display color of the first display screen is merely an exemplary illustration. In practical application, the display colors corresponding to the optical signal frequencies adopted by different LiFi connections can be set according to actual needs.
Further alternatively, the optical signal frequency and the display color may not have a fixed corresponding relationship, and the change of the adopted optical signal frequency may be prompted by the change of the color.
Furthermore, as indicated above, during the LiFi connection process, the first electronic device may not only transmit the light signal through the first display screen, but also transmit the light signal through a light emitting unit of the type of LED breathing lamp or the like. Accordingly, when the frequency of the optical signal used for the LiFi connection is changed, the color of the optical signal of the light emitting unit such as the LED breathing lamp may be switched.
The following describes a file transmission method provided in the embodiments of the present application with reference to a specific application example.
As shown in fig. 2, in this specific application example, a mobile phone a (corresponding to a first electronic device) and a mobile phone B (corresponding to a second electronic device) may perform LiFi communication. Accordingly, the file transfer method may include:
specifically, the mobile phone a may receive a selection input of a user when a file interface is displayed, and may determine a target file to be transmitted in response to the selection input of the user.
in this step, the mobile phone a and the mobile phone B are bright and opposite, and can be considered as a visual representation form for establishing the LiFi connection.
In particular, the frequency of flicker of the light signal used for the LiFi connection is often difficult to perceive by the human eye. The LiFi technology generally adopts visible light wireless communication, so that reliable LiFi connection can be realized between the mobile phone a and the mobile phone B under the condition that the mobile phone a and the mobile phone B are opposite in bright screen.
as shown above, the process of establishing the LiFi connection between the mobile phone a and the mobile phone B may be that the mobile phone a sends the first optical signal when receiving the selection input of the target file. Cell phone B, upon receiving the first light signal, may send a second light signal in response to the first light signal to indicate agreement to establish a LiFi connection with cell phone a. The first electronic device may establish a LiFi connection with the second electronic device in response to the second optical signal when receiving the second optical signal.
this step may be considered as a process of determining whether the mobile phone a receives the first input.
that is, handset a starts sending the target file to handset B based on the LiFi connection.
for example, the prompt box may show "do you receive a file from a? And the prompt text of the user is displayed with two operation controls with the names of rejection and acceptance.
And judging whether the actual B receives, namely judging the input of which operation control of the two operation controls of 'refusing' and 'accepting' is input by the user. If the user clicks "reject", the file transfer fails. And if the user clicks 'accept', transmitting the target file until the target file is transmitted successfully.
