System and method for transmitting data using barcode

Abstract

The invention discloses a system and method for transmitting data using barcode. The system comprises a first terminal and a second terminal; each of the first terminal and the second terminal is provided with a HD digital interface, and the first terminal and the second terminal are connected through a HD video wire, wherein the first terminal further comprises a barcode conversion module for acquiring to-be-transmitted data from the first terminal, converting the data into the barcode capable of bearing data and data identification, and transmitting the barcode to the second terminal; the second terminal further comprises a video acquiring card and a barcode analysis module, the video acquiring card is used for acquiring the barcode and sending the barcode to the barcode analysis module; the barcode analysis module is used for analyzing the barcode, and transferring the analyzed barcode to the second terminal. Through the adoption of the system disclosed by the invention, the data exchange can be performed between the computers in network isolation.

Description

technical field [0001] The invention relates to a data exchange system and method between computers, in particular to a data exchange system and method between computers realizing network isolation. Background technique [0002] At present, there are a large number of scenarios where intranet data needs to be retrieved under network isolation conditions. Due to security requirements, intranet data cannot be obtained through the network. The resulting data acquisition work is very difficult. Manual acquisition is time-consuming and the data cannot guarantee timeliness, or cannot obtain this part of the data at all. Therefore, how to obtain data through the isolated network has become a problem that plagues the daily work of technicians.

Due to security requirements, intranet data cannot be obtained through the network

As a result, the data acquisition work is very difficult

Manual acquisition is time-consuming and the data cannot guarantee timeliness, or cannot obtain this part of the data at all. Therefore, how to obtain data through the isolated network has become a problem that plagues the daily work of technicians

[0003] In the existing technology, on the core data transmission layer, a two-dimensional code scanning device is used to scan each two-dimensional code picture on the terminal display device, so the recognition will be affected by the properties of the display device (resolution, color difference, dust coverage caused by static electricity on the screen, Physical factors such as back shadow smear caused by long-term operation of the screen), scanning device properties (scanning frequency, lens vibration, lens dust coverage, resolution, photosensitive device long-term aging and other physical factors), the environment of display devices and scanning devices The influence of various factors such as light intensity, dust, physical occlusion, etc., will cause distortion of the scanning device and data identification errors, thus requiring frequent data accuracy verification and even data retransmission, which greatly affects the transmission quality and efficiency

At the same time, due to the method of scanning the terminal display device with the scanning device, the requirements for the operating environment are very strict and cannot meet the requirements of industrial transmission.
