Problems solved by technology

However, since the optical signal transmitter samples and converts each input audio signal, it can only be sent out through a single air channel, and the optical input received by the optical signal receiver can only be monophonic audio. signal, even if the sound playback device has a two-channel stereo function, it can only play mono sound

Embodiment 1

[0039] Please refer to figure 1 , figure 1 Shown is an implementation of a photon conference system, which includes a light emitting device 10 and a light receiving device 20 , the light emitting device 10 includes a first processing unit 12 and a light emitting unit 13 , and the first processing unit 12 and the light emitting unit 13 are connected by signal. The first processing unit 12 is used to process the input signal, including sampling the input analog signal and performing analog-to-digital conversion on the sampled data. In some embodiments, the first processing unit 12 also processes the analog-to-digital converted signal Perform encryption and other processing. Then the first processing unit 12 controls the light emitting unit 13 to emit light according to the processed data, converts the sampled data into a corresponding sequence of light signals and emits them. In this embodiment, the light emitting unit 13 includes an LED, and the LED is turned on or off under ...

[0061] Please refer to Figure 5 , in order to improve the light emitting effect, the first processing unit 12 and the light emitting unit 13 respectively have a plurality, and the light emitting device also includes an audio signal splitter 11, and the audio signal splitter 11 is connected with each first processing unit 12 for signal, and the audio signal The signal splitter 11 is used for dividing the first channel audio signal and the second channel audio signal input in parallel into multiple pairs of the first channel audio signal 14 and the second channel audio signal 15, and each pair of the first channel audio signal The channel audio signal 14 and the second channel audio signal 15 are respectively input to corresponding first processing units 12 , and the first processing units 12 are signally connected to the light emitting unit 13 respectively.

[0062] In some embodiments, there may be multiple light receiving devices 20, such as Figure 5 As shown, in this way,...

Embodiment 3

[0066] The difference between this embodiment and the above-mentioned embodiments lies in the different ways of distinguishing the data of each channel. In this embodiment, data of different channels are distinguished by adding corresponding data headers to the data of each channel. For example, the audio signal of the first channel and the audio signal of the second channel are distinguished by adding a data header to the sampling data of the audio signal of the first channel and the audio signal of the second channel. The data header refers to the header of a data packet composed of data sampled in each sampling period, and is used to mark the data packet. For example, the first processing unit processes the sampling data of each sampling period into a set format, and the format of the sampling data packet in the first sampling period is: the first data header + the sampling data of the first channel audio signal, and the second The format of the sampling data packet in the ...

Abstract

The invention discloses an optical communication system and a method and device for realizing multichannel signal transmission. A light sending device performs sampling on parallelly-input multichannel signals and performs processing on sample data; the sample data of each channel signal is converted into corresponding optical signal sequences and the optical signal sequences are sent out; a light receiving device receives the optical signal sequences sent by the light sending device, and converts the received optical signal sequences into electrical signal sequences; and the electrical signal sequences are processed and corresponding channels are identified. The multichannel signals can be transmitted in a single-channel optical communication channel, so that the receiving end can receive more groups of data.

Description

technical field [0001] The present application relates to an optical communication system, in particular to a method and device for realizing multi-channel signal transmission in the optical communication system. Background technique [0002] Optical communication technology is a new technology that transmits information by using high-speed bright and dark flickering signals invisible to the naked eye from fluorescent lamps or light-emitting diodes (LEDs). By changing the speed at which light-emitting diodes are turned on or off, different 1 and 0 sequences are given. Thereby encoding the data and disseminating it in free space. Then at the receiving end, it is decoded after being received by an optical receiver, and the original data and other information are recovered. [0003] In the current technology, since the signal is transmitted in the form of optical flicker, the air channel has only one channel. Therefore, after the optical signal transmitter samples and converts...
