Embodiment Construction

[0043] This application is based on the data input scheme of visible light graphics changes on the screen, relying on the electronic device screen to display brightness with a large contrast (such as black and white), the receiving end senses the brightness change through the photosensitive component, and converts it into a 0 / 1 signal, thereby performing data transmission . The whole screen can be used as a whole area to change black and white, or the screen can be divided into multiple areas arbitrarily, and the black and white states are displayed separately. The physical layout of the photosensitive part at the receiving end is consistent with the divided area displayed on the screen, and data can be transmitted in parallel to improve Data transfer efficiency. Use graphics with brightness changes to represent data information, and use photosensitive devices to identify the brightness of the graphics, thereby realizing information transmission. This solution has the charact...

Abstract

The application relates to a data transmission method, equipment and system. The method comprises the following steps: step 1, inputting data required to be displayed; step S2, converting the input data into a pattern having the brightness change; step S3, displaying the pattern; step S4, using a photosensitive device to read the pattern; step S5, recognizing the pattern and converting the pattern into data. According to the technical scheme, a technical problem in data transmission under the condition that a physical data interface or a wireless communication interface is not used or cannot be used is solved, and in addition, the problem solving manner has the advantages of being low in cost, wide in applicability, and capable of adapting to different screen resolutions and screen scaling.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a data transmission method, device and system thereof. Background technique [0002] Data transmission refers to the process of transmitting data between data sources and data hosts through one or more links in accordance with appropriate procedures. Also refers to the operation of sending data from one place to another by means of a signal on a channel. That is, one end transmits the command or status information to the other end through the channel, and is received by the other end. Includes sending and receiving. Among them, the transmission medium is divided into wired and wireless. The wired is a telephone line or a dedicated cable; the wireless is the use of radio, microwave and satellite technology. The information cannot be changed during transmission, nor can the information itself be sent or received. There must be a carrier, such as data, lan...
