Problems solved by technology

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.

Embodiment 2

[0059] Example 2 in figure 1 On the basis of the above, a barcode conversion module is added, and the barcode conversion module further includes:

[0060] A data segmentation module, configured to divide the data into at least one data segment;

[0061] a data conversion module, configured to convert the at least one data segment into a barcode containing data and a data identifier;

[0062] The barcode transmission module is used to output the generated barcode through the high-definition digital interface 13 in the form of video signal.

[0063] When the barcode conversion module converts the data into a barcode that can carry data and data identification, if the total data volume does not exceed the maximum data volume that the barcode can carry, the data is divided into one data segment, that is, the data is not divided. When the data is divided into a data segment, the data identifier includes a column header definition sequence and a data check code.

[0064] If the t...

Embodiment 3

[0078] The difference between embodiment 3 and embodiment 2 is that the data is transmitted from the first terminal to the second terminal at regular intervals, no matter whether the second terminal receives the data and parses the data incorrectly or not. Therefore, the function of the alarm module is also correspondingly different.

[0079] The alarm module further includes a terminal abnormal processing unit and a data abnormal processing unit. When the second terminal cannot obtain the bar code from the first terminal, the terminal abnormal processing unit sends an alarm; when the bar code analysis is unsuccessful, the bar code is marked and Stored in the second terminal, the first terminal continues to transmit the barcode to the second terminal; when the barcode is successfully parsed, the first terminal continues to transmit the barcode to the second terminal.

[0080] In the alarm module, the first terminal regularly transmits data to the second terminal, no matter whe...

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. [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 pro...
