Data transmission device

Abstract

The embodiment of the invention discloses a data transmission device, comprising a transmitting end and a receiving end. The transmitting end comprises: an encoding module and a display module, whichare connected to each other, wherein the encoding module is used for obtaining transmission data, and generating n frames of original data frames and m frames of inter-frame error correction data frames according to the transmission data, n and m are both natural numbers greater than 1, generating n+m frames of intra-frame error correction images according to n frames of original data frames and the m frames of inter-frame error correction data frames; the display module is used for displaying the n+m frames of intra-frame error correction images; the receiving end comprises: a decoding moduleand an image collection module, which are connected to each other, wherein the image collection module is used for obtaining multiple frames of intra-frame error correction images displayed by the display module; and the decoding module is used for restoring the transmission data obtained by the encoding module according to the multiple frames of intra-frame error correction images. The data transmission device provided by the embodiment of the invention has a data one-way transmission function under physical isolation conditions, and can realize the reliability and high rate of data transmission.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data transmission device. Background technique [0002] Data transmission is the communication process in which data is sent from one place to another. One-way transmission is a common data transmission method, which emphasizes one-way data transmission. For example, among the communication parties, one party is fixed as the sender, and the other is fixed as the receiver, and information can only be transmitted in one direction, that is, data can only be transmitted from the sender to the receiver. [0003] In the prior art, there are many methods for one-way transmission, such as: single-mode optical fiber, optical disk recording, one-way transmission based on image recognition technology, and the like. Among them, the single-mode fiber cannot achieve complete physical isolation. The capacity of CD burning is limited, and the failure rate is high. Af...

Problems solved by technology

[0004] The inventors of the present invention found that due to the characteristics of one-way transmission, the computer and the computer cannot complete the handshake process. When the computer fails to decode the picture and data packet loss occurs, the computer cannot be notified to retransmit, resulting in file transmission failure.

In order to ensure the reliability of transmission, the solution in the prior art is to reduce the image decoding error rate by reducing the information content of the image or prolonging the display time of the image, which makes the transmission rate significantly lower and cannot meet the needs of practical applications.
