Description

Technical Field

[0001] The present invention relates to the field of communication transmission technology, and specifically to a visible light communication transmission system and a transmission method based on big data calculation. Background Art

[0002] Visible light is the part of the electromagnetic spectrum that the human eye can perceive. The visible spectrum has no precise range. The frequency of electromagnetic waves that the average human eye can perceive is between 380-50THz and the wavelength is between 780-400nm, but some people can perceive electromagnetic waves with a frequency of about 340-790THz and a wavelength of about 880-380nm. The human eye with normal vision is most sensitive to green light. The range of light that the human eye can see is affected by the atmosphere, which is opaque to most electromagnetic radiation. The range of light waves that many other creatures can see is different from that of humans. For example, some insects, including bees, can see the ultraviolet band, which is very helpful for finding nectar. A recent study found that visible light may also be able to see through the flesh. General visible light communication transmission systems are unable to insert a dropout scheme for visible light communication information during communication transmission, resulting in a large gap in visible light communication information during transmission and reception, affecting the accuracy of visible light communication information transmission, and unable to conveniently and quickly extract the different current visible light communication information between transmission and reception. For this reason, we propose a visible light communication transmission system and transmission method based on big data computing. Summary of the invention
