Internal and external network physical isolation data transmission device

Abstract

The patent for invention relates to an internal and external network physical isolation data transmission device, comprising a physical isolation data transmission device box body, an image display device and an image identification device, wherein the transmission device box body is divided into an external network identification area and an internal network identification area, the two-dimensional code data information is displayed by using a cross display screen, an external network computer is connected with a camera, and the camera directly faces a display of the internal network to identify the two-dimensional code data transmitted by the internal network; the internal network computer is connected with the camera, the camera directly faces the display of the external network to identify the two-dimensional code data transmitted by the external network, and both the internal and external network computers are provided with a two-dimensional code data management software, a common data standard interface and transmission instructions; texts and pictures are subjected to automatic information preprocessing and coding, and then are subjected to image identification through the display to achieve uplink TX and downlink RX data transmission, and are parsed into data to store, add, delete and edit the instructions; and values are fed back after the data transmission is successful.

Description

technical field [0001] The patent of the present invention relates to a data transmission device for internal and external networks, in particular to a physical isolation data transmission device for internal and external networks. Background technique [0002] The government, army, armed police, public security, and military enterprises all have two or more networks. Due to security and confidentiality requirements, the internal network and external network cannot be interconnected with wired, wireless, and Bluetooth, nor can they pass through firewalls and gatekeepers. After filtering and connecting through technical means, it is required to achieve complete physical isolation. However, in the process of daily office and business processing, there are many data related to the synchronization and crossover of office and business data intranet and extranet. As well as mutual instant messaging, the current method can only manually synchronize data by copying the U disk or per...

Problems solved by technology

[0004] In order to achieve the above purpose, the present invention uses two-dimensional code image display and recognition technology to convert data and instructions such as pictures and text into QR two-dimensional codes, so as to achieve two-way data in a state of complete physical isolation between the internal network and the external network. The mutual transmission of information effectively solves the problems of inconvenient and untimely transmission of data on the traditional internal and external network, achieves security and confidentiality, and effectively prevents hackers from invading the internal network to steal secrets
