Visible light communication based data transmission method between computer and visible light transceiver

Abstract

The invention discloses a visible light communication based data transmission method between a computer and a visible light transceiver, and relates to a data transmission method based on the visible light communication, which solves the problems that the existing data transmission method between a USB interface and a computer is bad in security and severely limited by the USB interface. The transmission process I is as follows: a central processing unit (CPU) of the computer displays an image on the existing display screen and a display screen with the function of visible light communication; and the visible light transceiver focuses the image on a light sensor and performs self-adaptive amplification, matched filtering, sampling and judgment to the image to obtain the transmitting data of the computer. The transmission process II is as follows: the data to be transmitted is modulated and transmitted by a visible light communication luminescent area; and the computer focuses the visible light on the light sensor and performs self-adaptive amplification, matched filtering, sampling and judgment to obtain the transmitting data of the visible light transceiver. The data transmission method is applied to the data transmission between the computer and the visible light transceiver.

Description

technical field [0001] The invention relates to a data transmission method based on visible light communication. Background technique [0002] At present, with the popularization of computers, more and more people use computers to process data. The computers involved here include desktops, notebooks, personal digital assistants (PDAs), and smart phones with operating systems. After processing the data on the computer, if you need to transfer the data to other intelligent processors, you need to use storage devices, including U disk, SD card and many other options. The mainstream interface is to use Universal Serial Bus (Universal Serial Bus, abbreviated as USB), is a serial bus standard that connects computer systems and external devices. The USB interface is a commonly used interface in the current consumer electronics market, and its popularity is very high. If there is a USB interface in the computer, it can support the access of the USB device. On the one hand, this p...
