Embodiment 1

[0015] When transmitting data from the external network to the internal network, the external network computer two-dimensional code data management software interface obtains the transmitted data, generates two-dimensional code graphics after preprocessing and encryption, and outputs them to the 3.5-inch display screen, and the internal network computer two-dimensional code data The management software captures the two-dimensional code graphics of the display screen through the camera, decrypts them and restores them to the original data, and distributes them to the software or storage database through the software interface. After the two-dimensional code data management software is successfully connected, it will immediately generate special feedback graphics. Inform the computer on the external network that the data is received successfully.

Embodiment 2

[0017] Obtain data from the database for conversion and transmission. After the two-dimensional code data management software of the external network computer is bound to the database, a piece of data is added to the database, and the software automatically obtains the added content (divided into adding, deleting, and modifying instructions). After preprocessing and encryption Generate two-dimensional code graphics and output them to the 3.5-inch display screen. The two-dimensional code data management software of the intranet computer captures the two-dimensional code graphics on the display screen through the camera, decrypts them and restores them to the original data, and processes the database data according to the instructions through the software interface. Add, delete or modify, and feedback received instructions.

Embodiment 3

[0019] The troop vehicle dispatching system is installed on the internal network server, and the mobile phone SMS sending and receiving equipment is installed on the external network computer. When the user applies for a vehicle, he submits the vehicle application on the internal network office platform. After approval, the two-dimensional code data management software of the internal network computer obtains the The newly approved vehicle data is pre-processed and encrypted to generate a two-dimensional code graphic, which is output to the display screen. The external network computer two-dimensional code data management software captures the two-dimensional code graphic on the display screen through the camera and decrypts it. Restore to the original data and send the vehicle information to the driver's mobile phone through the SMS sending and receiving device, and drive the vehicle to the designated area.

[0020] Based on the above situation, through the above structural de...

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...
