Problems solved by technology

[0006] Although LIFI does have the advantage of not being interfered by radio signals, visible light cannot penetrate objects. When visible light is blocked by objects, communication will not be possible, which greatly affects the experience of LIFI communication.

Embodiment 1

[0054] refer to figure 1 as shown, figure 1 A flow chart of sending LIFI signals is provided for one example of the present invention.

[0055] Specifically, this embodiment provides a conversion method based on LIFI communication technology, the method includes the following steps:

[0056] Step1. When the first wireless device receives the communication signal, the first wireless device establishes a connection relationship with the second wireless device;

[0057] Step2. After establishing a connection relationship with the second wireless device, the first wireless device sends a first LIFI signal to the second wireless device;

[0058] Step3. The second wireless device receives the first LIFI signal and transmits it to the external device;

[0059] Step4. At the same time, the second wireless device returns the received first LIFI signal to the first wireless device;

[0060] Step5. The first wireless device receives the first LIFI signal returned by the second wirele...

Embodiment 2

[0065] refer to figure 2 as shown, figure 2 A flow chart of converting LIFI signals into WIFI signals is provided for one example of the present invention.

[0066] Specifically, this embodiment is basically the same as Embodiment 1, except that in this embodiment, after the second wireless device returns the received first LIFI signal to the first wireless device at the same time, the Methods also include:

[0067] Step40. If the first wireless device does not receive the first LIFI signal returned by the second wireless device within a first preset time;

[0068] Step41. Convert the LIFI signal into a WIFI signal and send it to the second wireless device;

[0069] Step42. The second wireless device receives the WIFI signal and transmits it to the external device.

[0070] Specifically, after the second wireless device returns the received first LIFI signal to the first wireless device, if the first wireless device does not receive the second wireless The first LIFI si...

Embodiment 3

[0073] refer to image 3 as shown, image 3 A flow chart for one example of the present invention to stop converting WIFI signals and continue sending LIFI signals.

[0074] Specifically, this embodiment is basically the same as Embodiment 2, except that in this embodiment, after the second wireless device receives the WIFI signal and transmits it to the external device, the method further includes:

[0075] Step43. The first wireless device sends a second LIFI signal to the second wireless device every second preset time; Step44. Detect whether the second wireless device returns a second LIFI signal to the first wireless device ;

[0076] Step45. If so, the first wireless device stops converting the LIFI signal into a WIFI signal, and continues to send the LIFI signal to the second wireless device;

[0077] Step46. The second wireless device receives the LIFI signal and transmits it to the external device.

[0078] Specifically, after the second wireless device receives t...

Abstract

The present invention relates to a method and system of conversion based on the LIFI communication technology. The method comprises: when a first wireless device receives LIFI signals, the first wireless device and a second wireless device establish a connection relation; in the connection relation of the first wireless device and the second wireless device, the first wireless device sends first LIFI signals to the second wireless device; the second wireless device receives the first LIFI signals and transmits the first LIFI signals to an external device and returns back the received first LIFI signals to the first wireless device; the first wireless device receives the first LIFI signals returned back by the second wireless device and detect whether the received first LIFI signals are consistent to the first LIFI signals sent by the first wireless device to the second wireless device or not; if yes, the first wireless device goes on sending LIFI signals to the second wireless device; and the LIFI communication is performed to ensure the integration of communication data and avoid loss of information data caused by blocking part of the second wireless device by users.

Description

technical field [0001] The invention relates to the communication field, in particular to a conversion method and system based on LIFI communication technology. Background technique [0002] Network communication has become a basic tool for information exchange between all walks of life in the world, but most of the existing communication networks and communication equipment are based on traditional communication protocols, and are all based on traditional physical links. Communication security not guaranteed effectively. [0003] Visible light wireless communication, also known as "light fidelity technology", the English name LightFidelity (LIFI for short) is a new wireless transmission technology that uses the visible light spectrum (such as the light emitted by a light bulb) for data transmission. Invented by the chairman of the department and the German physicist Professor Harald Hass (Harald Haas). [0004] LIFI uses the installed equipment (the ubiquitous LED lights)...
