Simultaneous translation system based on visible light communication

Abstract

The invention relates to a simultaneous translation system based on visible light communication. The simultaneous translation system comprises a wireless signal emission unit and a wireless signal receiving unit, wherein the wireless signal emission unit is used for emitting electrical signals sent by a main control computer through optical signals in a visible light mode, and the wireless signal receiving unit is used for receiving visible light signals and converting the visible light signals into signals capable of being recognized by people. According to the simultaneous translation system based on the visible light communication, the communication mode of the wireless signal emission unit and the communication mode of the wireless signal receiving unit are changed to a communication mode carried out by visible light, so spectrum resources do not need to be applied for by the visible light communication, no electromagnetic interference exists, no pollution exists, and stability and reliability of signal transmission are high. In addition, the visible light sent by the wireless signal emission unit can also be used for illuminating, and thus resource use efficiency can be improved.

Description

technical field [0001] The present invention relates to a language translation system, in particular to a simultaneous translation system based on visible light communication. Background technique [0002] A section of the spectrum with a wavelength from 0.76 to 400 microns is called infrared, and infrared is invisible light. All substances above absolute zero (-273.15°C) can produce infrared rays. In recent years, infrared rays have been widely used in military affairs, artificial satellites, industry, health, and scientific research. For example, existing simultaneous translation systems usually transmit signals through infrared rays. [0003] However, infrared is a kind of heat radiation, which can cause high temperature damage to the human body, so the problem of infrared pollution also arises. Stronger infrared rays can cause skin damage similar to a scald, initially with a burning pain and then a burn. Since the eyeball contains more liquid and absorbs infrared rays...

Problems solved by technology

[0004] In addition, there are still the following problems in the transmission of infrared rays indoors: 1. Infrared rays are directional in the transmission process. It relies on the reflection of the surrounding environment to transmit light to places that cannot be reached by direct light. However, the actual environment is very different. , the reflection performance that can be provided may be very poor, so there may be a dead zone in the space, and the signal cannot reach, causing serious problems in the use process

2. The infrared rays used for signal transmission are very weak, and all kinds of light in the natural environment are very strong. In some cases, the ambient light will drown the signal light, causing the communication to be interrupted

Therefore, how to solve the pollution caused by the existing infrared rays and the stability and reliability of signal transmission have become an urgent problem to be solved today.
