Problems solved by technology

But this technical scheme has the following defects: on the one hand, the blank disc magazine, the recording disc drive, the read-only disc drive and the recovery disc magazine form a rectangular array, and the manipulator moves between them
Since the internal network CD-ROM drive is connected to the internal network, and the external network CD-ROM drive is connected to the external network, the internal and external network CD-ROM drives are separated. In order to ensure the physical isolation of the internal and external networks, the CD-ROM as a data carrier must be moved between the internal network and the external network CD-ROM drive. The movement of the CD-ROM It must rely on the operation of the manipulator to realize, such as the manipulator grabs the plate and puts the plate, resulting in the whole device being bulky, heavy and expensive
On the other hand, due to the limited number of blank discs contained in the disc magazine, it is easy to have insufficient blank discs during the data exchange process, which requires artificially adding discs, which cannot meet the needs of long-term unattended ferry machines

Abstract

The invention discloses a physical isolation data transmission device comprising a data loading module, a data reading module, a data recording medium and a ferrying mechanism; the data loading moduleis used for loading data into the data recording medium; the data reading module is used for reading data in the data recording medium; the data loading module and the data reading module are spacedfor a certain distance in space; the ferrying mechanism is used for carrying the data recording medium and driving the data recording medium to move between the data loading module and the data reading module. The data loading module and a data transmission module form no connection and data communication and strict physical isolation is achieved; the ferrying mechanism only needs to carry the data recording medium such as a CD to move, so that the operation that a manipulator grabs and places CDs is avoided, the difficulty and the complexity of mechanical control are effectively reduced and the data transmission speed is greatly increased.

Description

technical field [0001] The invention relates to data storage and data transmission, in particular to a physically isolated data transmission device and method. Background technique [0002] In data communication, networks with different security levels can be between internal networks and external networks, or between public networks and private networks, and between confidential networks and non-secure networks. In order to realize and ensure the security of the network data exchange process, the safest way is to separate physically and realize "physical isolation" between different levels of networks. [0003] Current data storage media mainly include optical discs, magnetic disks, magnetic tapes, and the like. As a stable storage carrier, optical discs are often used to save important data. In the process of data storage, first burn the data stored in the external network to a blank CD, and then store the data stored in the burned CD to the internal network for preserva...
