Abstract

The invention provides an optical communication transmission method and system. The optical communication transmission method includes encoding to-be-sent transmission data by bit to obtain an electric signal formed by combination of a high level and a low level; controlling a designated area of a screen to send out an optical signal of flash time corresponding to the high and low levels of the electric signal; receiving the optical signal, and converting the optical signal into the electric signal composed of the high and low levels; recording duration for converting the optical signal into the electric signal composed of the high and low levels, and decoding the electrical signal to obtain the transmission data. The screen of terminal equipment is utilized for performing optical communication, an optical communication module occupies a small internal space of the terminal equipment, complicated communication protocol stack support is not required during optical communication, and external communication equipment can receive information sent from the terminal equipment only by being provided with an optical receiver, so that the optical signal only needs to be encoded and decoded simply, the structure of the whole system becomes simple, and research and development costs are saved.

Description

technical field [0001] The invention belongs to the field of optical communication, and in particular relates to an optical communication transmission method and system. Background technique [0002] The current mainstream short-range wireless communication technologies include Wi-Fi technology, Bluetooth technology, NFC technology, Zigbee technology, IrDA infrared technology and UWB ultra-wideband technology. Among them, Wi-Fi and Bluetooth technology have become the mainstream configuration of mobile phones. While other technologies are rarely carried on mobile phone platforms, only NFC technology is carried on a small number of high-end models. Therefore, Wi-Fi and Bluetooth, as mainstream technical standards, are more commonly used communication solutions in current mobile phone peripherals. [0003] However, the use of Wi-Fi technology or Bluetooth technology requires the configuration of corresponding communication modules, and these modules usually occupy a large ar...
