Embodiment Construction

[0033] In the data transmission method, device, and electronic equipment of the embodiments of the present invention, the light-fidelity LiFi signal is sent at the sending end through a plurality of light-emitting units on the electronic equipment, and the light-fidelity LiFi signal is received at the receiving end through a light sensor on the electronic equipment. Real LiFi signal, and use it to restore the data sent by the sender. Compared with the prior art, it sends optical fidelity LiFi signals through multiple light-emitting units. Therefore, under the same transmission rate requirements, the transmission rate requirement of each light-emitting unit is greatly reduced, so it can also reduce the number of LiFi transmission devices. performance requirements.

[0034] The data transmission method of the first embodiment of the present invention, such as figure 1 shown, including:

[0035] Step 101, encoding the data to be transmitted to obtain a plurality of encoded data...

Abstract

The invention discloses a data transmission method and an electronic device. The device performance demand for LiFi transmission is reduced. The data transmission method comprises the steps of coding to-be-transmitted data, thereby obtaining multiple coding data sequences in one to one correspondence to multiple light emitting units of the electronic device; generating multiple drive signals for driving the corresponding light emitting units according to the multiple coding data sequences; and outputting the multiple drive signals to the corresponding light emitting units, and driving the multiple light emitting units to send light fidelity LiFi signals, thereby enabling a receiving end to restore the to-be-transmitted data by employing the light fidelity LiFi signals. According to the method and the device, the device performance demand for LiFi transmission is reduced.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method and electronic equipment. Background technique [0002] At present, electronic devices are becoming more and more popular, which brings great convenience to users in information exchange and information sharing. With more and more electronic devices, data transmission among different electronic devices becomes more and more frequent. [0003] The short-distance data transmission between electronic devices can now be realized through optical fidelity LiFi technology. [0004] Light-fidelity LiFi is a technology that uses visible light for wireless communication, which uses the visible light spectrum (such as the light emitted by a light bulb) for data transmission. Light-fidelity LiFi technology transmits information by controlling visible light sources (such as light-emitting diodes (LEDs)) to emit high-speed flashing signals invisible to th...
