Problems solved by technology

[0004] It can be seen that in the one-way data transmission process using the "data pump" technology, although the data is transmitted in one direction, the control information can be transmitted in two directions. In the above transmission process, there are still potential safety hazards for high-level confidentiality equipment

Abstract

The embodiment of the invention provides a data transmission equipment and method. The method can be applied to the data transmission equipment. The data transmission equipment comprises an input endcircuit and an output end circuit. The input end circuit comprises an input interface, a first processor and a display part. The output end circuit comprises a scanning part, a second processor and anoutput interface. The first processor of the input end circuit can convert the data acquired through the input interface into the graphic code and transmit the graphic code to the display part of theinput end circuit so as to be displayed through the display part. Then the scanning part in the output end circuit scans the graphic code displayed by the display part and transmits the graphic codeto the second processor in the output end circuit. With application of the data transmission equipment and method, unidirectional data transmission can be realized, i.e. unidirectional transmission ofthe data can be realized.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission device and method. Background technique [0002] Due to its particularity, many application fields have high requirements for data security. In some application fields, data exchange and sharing must strictly abide by the corresponding regulations and standards. For example, data can only be transmitted from one end device to the other end device, that is, during the transmission process, the unidirectionality of data transmission must be guaranteed. For example, among devices with different data confidentiality levels (network security levels), data can only be transmitted from devices with low confidentiality levels (devices with low network security levels) to devices with high confidentiality levels (devices with high network security levels). [0003] At present, the "data pump" technology is generally used to realize the unidirectional...
