Abstract

The invention provides a visible light communication method and a terminal. The problems that after visible light data transmission is interrupted, when data transmission is carried out again, transmission needs to be carried out again, and continuous transmission cannot be carried out are solved. The visible light communication method comprises the steps that visible light signals carrying data information are transmitted to the second terminal; if visible light signal transmission is interrupted, the transmission progress of the data information is acquired, and the data information is stopped from being transmitted to the second terminal; if visible light signal transmission is restored, the data information is continuously transmitted according to the transmission progress of the data information, and data transmission does not need to be restarted. Data transmission efficiency is improved, and then the user experience to visible light data transmission is improved.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a visible light communication method and terminal. Background technique [0002] With the advent of the information age, the amount of information transmission is increasing, and the requirements for information transmission speed are getting higher and higher. At present, data communication methods are mainly divided into wired and wireless. Commonly used wireless communication is based on WI-FI technology, but WI-FI communication has the problem of signal instability, and its speed is not high enough for the transmission of large amounts of data. Therefore, based on the higher requirements for wireless communication speed, visible light communication technology has developed accordingly, and is expected to become the next generation communication technology. Visible light communication technology has obvious advantages in transmission speed and can b...
