Data bidirectional transmission equipment and method based on two-dimensional code

Abstract

Data bidirectional transmission equipment based on a two-dimensional code comprises a two-dimensional code scanning gun, a two-dimensional code display, an extranet front main station and a mobile phone, the two-dimensional code scanning gun and the two-dimensional code display are fixedly mounted on the opposite side; data obtained from an intranet system is encrypted and packaged into a two-dimensional code, the two-dimensional code is put on the two-dimensional code display, the two-dimensional code scanning gun scans the two-dimensional code on the two-dimensional code display in real time, and the two-dimensional code content is scanned and analyzed immediately after the two-dimensional code is found and pushed to a mobile phone through the extranet front main station; a person receiving the information push feeds back processing information to the extranet front main station on site through the mobile phone, and the extranet front main station encrypts and encapsulates the feedback information into a two-dimensional code, and the two-dimensional code is read by the two-dimensional code scanning gun and then transmitted back to the intranet system. A method is also provided.

Description

technical field [0001] The present invention relates to the technical field of information transmission, in particular to a two-dimensional code-based data two-way transmission device and a two-dimensional code-based data two-way transmission method. Background technique [0002] According to the "Computer Information System International Internet Secrecy Management Regulations" promulgated and implemented by the State Secrets Bureau, the regulations on the use of the Internet by state confidential departments are as follows: "Computer information systems involving state secrets shall not be directly or indirectly connected to the Internet or other public information networks. , Physical isolation must be implemented.” The so-called physical isolation means that if the internal LAN of the enterprise does not have a direct physical connection with the Internet at any time, the network security of the enterprise can be truly protected. [0003] After the "intranet" and the Int...

Problems solved by technology

[0008] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a two-dimensional code-based data bidirectional transmission method, which not only effectively solves the problem of large resource consumption of optical disks but also realizes complete physical isolation, The two-way transmission function of data is realized, not only one-way data transmission, but also the data transmission of internal network equipment (external network equipment) to external network equipment (internal network equipment), which solves the security problem of data transmission and effectively Solved the alarm problem when inserting input and output devices
