Abstract

The invention discloses a data storage system based on visible light communication which comprises a light signal transmission system, an electronic lock system and a data storage system, wherein the light signal transmission system is used for transmitting light signals; the electronic lock system is used for converting the light signals into digital signals and unlocking an electronic lock according to the digital signals; the data storage system is used for storing and checking the unlocking information in the electronic lock system; and the data storage system comprises a database module for storing the unlocking information and a terminal device for reading the unlocking information. According to the invention, the unlocking function is realized by adopting a light communication mode, the transmission rate reaches 1 kilomega per second, and the visible light is adopted for transmitting the data for light transmission, and the data is difficult to interfere and capture; and a database storage technology is also utilized, the unlocking information is stored, the data storage system is convenient to maintain and manage, and the safety performance of the visible light communication can also be enhanced.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a visible light communication method and a data storage system based on visible light communication. Background technique [0002] As a necessary system for companies, shopping malls and other places, the access control system has a variety of implementation forms to achieve the purpose of the access control system. Most of the access control systems in the prior art are implemented using radio frequency or infrared technology. [0003] The unlocking radio frequency card needs to be close to the access control system to open the access control, which has high requirements for the receiving range and receiving accuracy of the radio frequency access control system. In addition, the crosstalk of the unlocking radio frequency card is very serious. When multiple radio frequency access control cards are stacked together, each The function of an access control car...
