The present invention discloses a method for realizing file transmission, a device and a system. When file information is sent, a file is encoded to generate bit information, the m consecutive bit information is mapped into corresponding gray value information orderly, and the gray value information are grouped to obtain a screen frame sequence, wherein only the gray value information in the same screen frame is displayed in the screen in the same transmission period, the gray value information in each screen frame is displayed by screens in order such that a receiving device collects the images displayed in the screen, and thus the transmission of the file to the receiving device is realized. The data real-time transmission is realized by the modes of screen display and image collection, the transmission process is simplified, the speed and reliability of data directed transmission are improved, the problems of easy interference and low transmission rate of an existing system are solved, and conditions are created for reliable transmission and big data application.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for realizing file transmission. Background technique [0002] The traditional end-to-end file transfer methods mainly include Bluetooth, data cable, infrared ray, WiFi, etc. These methods solve the problem of user file transfer and improve the transmission speed, but at the same time, they also have complex operation methods, poor confidentiality, There is a bottleneck in the transmission speed and there is little room for speed improvement. [0003] Visible Light Communication (VLC for short) is a new type of wireless communication technology based on visible light. Visible light communication can provide a short-distance, safe, and interference-free wireless link. Compared with traditional radio frequency communication, it has obvious advantages. However, the current visible light communication technology has a small amount of transmitted informa...
