Cross-network optical turntable isolation ferry machine and cross-network automatic data ferry method

Abstract

The invention discloses a cross-network optical turntable isolation ferry machine and a cross-network automatic data ferry method. The cross-network optical turntable isolation ferry machine comprises a coaxial isolation optical turntable, a volatile memory, an optical receiving and optical transmitting communication module, a stepping motor and a servo controller, the coaxial isolation light turntable comprises two coaxial discs, namely a receiving light path control disc A and a sending light path control disc B; each of the coaxial discs A and B comprises an on part, an off part and a stop part; and'through 'parts in the A and the B are in a mutual exclusion state. The coaxial isolation optical turntable is used for controlling data receiving and transmitting; comprising the following steps: receiving extranet data and caching the extranet data into a volatile storage; ferrying the cached data to an intranet; and clearing the ferry cache data. According to the invention, volatile storage is used across networks to realize optical one-way ferry isolation of stored ferry data, automatic data exchange of internal and external networks in pure physical isolation can be realized, automation and zero material consumption of data ferry are realized, and manual monitoring and emergency data interruption can be carried out at any time.

technical field [0001] The invention belongs to the technical field of information transmission, and relates to a cross-network data transmission technology using volatile storage (RAM) for cross-network isolation and cross-network data transmission, in particular to a cross-network automatic data transmission ferry (exchange) for optical turntable isolated ferry A device and its data ferrying method. Background technique [0002] Most of the technologies currently used in the field of cross-network data ferry transmission technology include: 1. Physically isolated optical disc ferry scheme; 2. Physically isolated RAM electronic disk data ferry scheme; 3. Physically isolated static storage (U disk, mobile Hard disk, etc.) ferry program. The shortcomings of several existing physically isolated ferry technologies include: [0003] The optical disc ferry scheme using physical isolation, also known as the optical disc ferry machine, is a semi-automatic data ferry scheme that r...

AI Technical Summary

Problems solved by technology

[0003] The optical disc ferry scheme using physical isolation, also known as the optical disc ferry machine, is a semi-automatic data ferry scheme that requires manual replenishment and destruction of optical discs on a regular basis, and the ferry efficiency is low;

[0004] The use of physically isolated RAM electronic disk data ferry can effectively solve the problem of one-way data storage and loss and destruction of optical disks, but it is necessary to manually copy the data into the RAM electronic disk on the external network, and then enter the internal network to manually copy the data to the internal network computer. Desktop applications are inefficient in the exchange of large amounts of data across networks

[0005] When using the static storage solution for internal and external network data transfer, one-way transmission of data cannot be guaranteed, and unauthorized use and attacks of viruses and Trojan horses on storage devices cannot be effectively controlled, which may easily cause sensitive data leakage
