Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The LiFi principle is that information is encoded in light according to different rates, for example, LED indicates 1 on and 0 off, and information can be transmitted by switching fast. Because of the luminous intensity of the LED, human eyes can not notice the rapid change of light, and the lamp bulb can twinkle at a very high speed by adding the microchip on the common LED lamp bulb, so that the lamp bulb can be used for sending data. And the flashing frequency of the bulb reaches millions of times per second, and by the mode, the LED bulb can rapidly transmit the binary codes. However, the flicker is invisible to the naked eye and can only be detected by the photosensitive receiver, so that the normal use of the LED lamp is not influenced.
The data is pushed through the LiFi technology, and the data pushing method is very effective in certain occasions, such as meeting content pushing and postcard pushing in meeting occasions, preferential information pushing and product information pushing to users in shops, and the like.
Referring to fig. 1, an application scenario provided in an embodiment of the present invention is shown, which may include: hotspot service equipment and terminal equipment. Wherein, the hot spot service equipment is an LED light receiving/transmitting device connected with the Ethernet. The device can be an LED bulb which is additionally provided with a microchip and connected with the Ethernet, and can transmit and receive light signals with different flicker frequencies. The terminal device is a terminal device with an LED light receiving/transmitting function. The terminal device can be a mobile phone, a tablet personal computer and the like, and can transmit and receive optical signals with different flicker frequencies as hot spot service equipment.
Example one
Referring to fig. 2, a flow of a visible light wireless communication method provided by an embodiment of the present invention is shown, where the flow may be applied in a scenario as shown in fig. 1, and the method may include:
s101, the hotspot service equipment sends a broadcast to the terminal equipment through a public channel to request to acquire the identification number of the terminal equipment.
It should be noted that the common channel refers to a channel that can be transmitted, received, and analyzed by both the hotspot service device and the terminal device. For example, when the hotspot service device is an LED lamp connected to the ethernet network, a fixed flashing frequency of the LED lamp may be used as the common channel. The identification number of the terminal device may be a unique serial number representing the terminal device, for example, each terminal device such as a mobile phone or a tablet computer has an ID number representing its identity, and the uniqueness of subsequent channel allocation can be realized by using the ID number of the terminal device.
S102, after receiving the broadcast sent by the hotspot service equipment through the public channel, the terminal equipment sends the identification number of the terminal equipment to the hotspot service equipment.
It will be appreciated that when the terminal device receives information on the common channel before the dedicated channel is not allocated, the terminal device first parses the received information. After receiving the broadcast sent by the hotspot service equipment through the public channel, the terminal equipment analyzes that the content contained in the broadcast message is the message of the hotspot service equipment asking for the identification number, and therefore, the terminal equipment sends the identification number of the terminal equipment to the hotspot service equipment.
S103, the hotspot service equipment receives the identification number sent by the terminal equipment and allocates a special channel for the terminal equipment corresponding to the identification number.
It can be understood that, the identification numbers of each terminal device, such as the ID numbers, are unique and different, so that the hotspot service device allocates a dedicated channel to the terminal device corresponding to the ID number by using the ID number of the terminal device as a unique identifier, and channel repetition is not caused. Here, the dedicated channels of different terminal devices correspond to different flashing frequencies of the LED lamp, i.e., the on-off frequency of the LED lamp.
And S104, the hotspot service equipment generates channel setting data according to the identification number and the special channel allocated to the terminal equipment, and sends the channel setting data to the terminal equipment through a public channel.
It should be noted that the hotspot service device uses the identification number of the terminal device as a header of the channel setting data, and uses a dedicated channel allocated to the terminal device, that is, the on-off frequency of the LED lamp, as a message of the channel setting data. The channel setting data is a message which is sent to the terminal equipment by the hotspot service equipment and used for informing the terminal equipment that a special channel is allocated to the hotspot service equipment.
And S105, the terminal equipment receives the channel setting data sent by the hotspot service equipment on the public channel and sends a confirmation message to the hotspot service equipment through the public channel.
It can be understood that the terminal device responds to the hotspot service device according to the received channel setting data, and confirms to receive the channel setting data. After receiving the dedicated channel, the terminal device opens a function of data transceiving with the hotspot service device through the dedicated channel, and performs data interaction with the hotspot service device.
And S106, after receiving the confirmation message of the terminal equipment, the hotspot service equipment takes the identification number of the terminal equipment as a header and the data to be sent as a message when sending the data, and sends the data to the terminal equipment on the allocated special channel.
Specifically, after the hotspot service device establishes a connection relationship with the terminal device through a dedicated channel, the hotspot service device can send data to the terminal device on the dedicated channel, so as to realize data interaction between the hotspot service device and the terminal device.
S107, the terminal device receives the data sent by the hotspot service device through the allocated dedicated channel, and performs data interaction with the hotspot service device.
Based on the above visible light communication method flow, the visible light communication method according to the embodiment of the present invention will be further described in detail below by taking an actual conference scene as an example:
terminal devices with a LiFi communication function can form a small local area network, and each terminal is allocated with a dedicated communication channel besides a common channel for communicating with the hot spot service device LiFi. And in a meeting scene, the terminal equipment starts the installed application software and interacts with the hotspot service equipment through the application software.
It should be noted here that the interaction between the hotspot service device and the terminal device may be a one-to-one interaction or a one-to-many interaction, that is, one hotspot service device may implement communication with multiple terminal devices. In the conference scenario, one-to-many interaction is performed between the hotspot service device and the terminal device. In a local area network formed by hotspot service equipment and terminal equipment, the hotspot service equipment firstly sends a broadcast to the terminal equipment through a public channel to ask for an identification number of the terminal equipment, such as an ID number of the terminal equipment. After receiving the broadcast, each terminal device in the local area network sends its own identification number to the hotspot service device. The hotspot service equipment allocates a special channel to the terminal equipment corresponding to the identification number of each terminal equipment, and channel setting data consisting of the identification number of each terminal equipment and the special channel is sent to the corresponding terminal equipment. The LED lamps of each dedicated channel have different on-off frequencies, and each dedicated channel receives and transmits data at a specific frequency. After all terminal devices in the meeting scene receive the channel setting data, the data transceiving function of the corresponding dedicated channel is opened, and the data transceiving function is used for receiving the information sent by the hotspot service device.
In the above process, the hotspot service device and the terminal device establish a data interaction relationship through the allocated dedicated channel, so that in the meeting scene, the terminal device can perform data interaction with the hotspot service device.
As shown in fig. 3, the roles of the participants can be selected on the application interface of the terminal device, and the default role is an audience, including the roles of an administrator, a host, an invited guest, and the like in addition to the audience. Wherein, different roles have different permissions, such as: the administrator can set the contextual model of the other terminals, and the host can share the conference content to the other terminals, and in addition, all participants including invited guests can distribute the electronic business cards to the other terminals.
The following will provide a process of data transceiving between the hotspot service device and the terminal device after the hotspot service device and the terminal device establish a data interaction relationship in a conference scene:
fig. 4 is a schematic diagram illustrating information configuration when an administrator performs scene setting in the conference scene. Under the interface, the administrator can configure the switches of some functions, wherein wifi, Bluetooth, GPS and the configuration of the reminding mode of information or incoming calls, such as the on or off of functions of vibration, sound and the like, are listed. And when the button of 'selecting participant to send' is clicked, popping up terminal equipment which is currently added into the local area network in the conference room, and selecting part of the terminal equipment to send configuration information or all the terminal equipment to perform group sending. And the terminal equipment of the administrator encodes and modulates the content of the configuration options and the information whether to be sent in groups to form a digital signal, and sends the digital signal to the hotspot service equipment through a special channel of the terminal equipment of the administrator.
And after receiving the scene configuration information sent by the administrator terminal equipment, the hotspot service equipment analyzes the received configuration data and sends the configuration information to the selected other terminal equipment. The hotspot service equipment firstly judges whether to perform group sending on the configuration information according to the analyzed information. If the configuration information relates to all the terminal devices, the hotspot service device transmits the configuration information to all the terminal devices in a unified way through a common channel; if only part of the terminal devices are involved, the hotspot service device sends the messages according to the allocated dedicated channel of each involved terminal device, and specifically, the messages can be sent in a frequency division multiplexing mode.
After the terminal equipment receives the configuration information, a prompt box for indicating whether the terminal equipment is configured according to the information or not is popped up on an interface of the terminal equipment, if wifi is opened or the incoming call reminding mode is changed into mute mode, wherein the prompt box can not be started any more next time under the condition that a user authorizes the terminal equipment. And after receiving the prompt box, if the user selects yes, configuring the terminal equipment according to the analyzed configuration information. If the user chooses no, the prompt box disappears and no other processing is performed.
The scene setting completes the data interaction process that the terminal equipment of the administrator sends the scene configuration information to the hotspot service equipment through the special channel of the terminal equipment of the administrator, and the hotspot service equipment sends the scene configuration information to the terminal equipment selected by the administrator through the corresponding channel. In addition to the fact that the administrator performs scene configuration on other terminal devices in the meeting scene, the terminal device of any participant can also send an electronic business card to the terminal devices of other participants.
Fig. 5 shows a function of the terminal device transmitting an electronic business card to the other terminal device. When the business card is clicked in the application, a contact person interface pops up, after a certain contact person is selected in the contact person interface, an interface as shown in fig. 5 pops up, and the interface displays the basic information of the selected contact person. Further editable buttons may also be added to the interface to allow the user to further edit the information. After the selected contact information is completed, the selected contact information can be sent to users of other terminal devices as electronic business cards. After the 'select participant send' button is clicked, the interaction process of the scene configuration information and the hotspot service equipment is the same, after the terminal equipment user sending the electronic business card selects the terminal equipment user receiving the electronic business card, the electronic business card is sent to the selected terminal equipment receiving the electronic business card through the hotspot service equipment, and therefore the interaction process of sending the electronic business card to the corresponding terminal equipment is completed.
The embodiment of the invention provides a visible light wireless communication method, wherein hot spot service equipment allocates special channels for different terminal equipment by using different on-off frequencies of LED lamps, and then establishes a data interaction relation with the terminal equipment through the special channels to realize accurate and timely data interaction between the hot spot service equipment and the terminal equipment.

Step S200 is further included before step S201:
s200, the hotspot service equipment sends a broadcast to the terminal equipment through a public channel to request to acquire the identification number of the terminal equipment.
It will be appreciated that the hotspot service device interacts with the terminal device over the common channel before the terminal device is not assigned a dedicated channel. When the hotspot service device interacts with some terminal devices of all the terminal devices in the local area network independently, the hotspot service device needs to establish a dedicated channel with the terminal devices independently. The ID number of the terminal equipment can be used as a unique identifier, and a special channel is established with the terminal equipment by utilizing different on-off frequencies of the LED lamps.

Specifically, after allocating a dedicated channel to a terminal device, the hotspot service device needs to send the setup data of the dedicated channel to the corresponding terminal device. Therefore, the header of the channel setting data may be an identification number of the terminal device, which is used to lock the terminal device receiving the message; the message of the channel setting data is a dedicated channel allocated to the terminal device, so that the terminal device can accurately set the channel of the terminal device according to the channel setting data.
And S2022, the hotspot service equipment sends the channel setting data to the terminal equipment through the public channel.
It is understood that since a dedicated channel has not been established with the terminal device, the hotspot service device can transmit the channel setting data to the terminal device only through a common channel.
And S2023, after receiving the confirmation message of the terminal device for the channel setting data, the hotspot service device establishes a data interaction relationship with the terminal device.
Specifically, the hotspot service device sets a channel for the terminal device, and establishes a dedicated channel for data interaction with the terminal device, and then can independently communicate with the terminal device through the dedicated channel, thereby realizing rapid and accurate interaction of data.
And S203, the hotspot service equipment sends channel interaction data to the terminal equipment through the dedicated channel by using the data interaction relation.
Specifically, referring to fig. 8, step S203 includes steps S2031 and S2032:
s2031, the hotspot service device determines that the identification number of the terminal device is a second header, determines that the interactive data is a second message, and combines the second header and the second message to generate the channel interactive data.
It can be understood that, after the hotspot service device establishes the data interaction relationship with the terminal device, the hotspot service device may send the interaction data to the terminal device through the dedicated channel. And generating interactive data to be sent to the terminal equipment by taking the identification number of the terminal equipment as a header and the interactive data to be sent as a message.
S2032, the hotspot service device sends the channel interaction data to the terminal device through the dedicated channel.
As can be understood, after the interactive data is generated, the hotspot service device may send the interactive data to the terminal device corresponding to the dedicated channel through the dedicated channel, so as to implement data push.
The embodiment of the invention provides a visible light wireless communication method, wherein hot spot service equipment allocates special channels for different terminal equipment by using different on-off frequencies of LED lamps, and then establishes a data interaction relation with the terminal equipment through the special channels to realize accurate and timely data interaction between the hot spot service equipment and the terminal equipment.

Specifically, referring to fig. 10, step S301 includes steps S3011 to S3013:
s3011, after receiving a broadcast of a request sent by the hotspot service device for acquiring the identification number of the terminal device, the terminal device sends the identification number of the terminal device to the hotspot service device through a public channel.
It can be understood that, after receiving the broadcast of the hotspot service device asking for the identification number, the terminal device sends the identification number of the terminal device to the hotspot service device to establish a dedicated channel with the hotspot service device.
