Physical isolation device and data transmission method

Abstract

The invention provides a physical isolation device and a data transmission method. The physical isolation device comprises a CD recorder electrically connected to an internal network server, a CD wiper, a CD reader electrically connected to an external network server, a carrier vehicle and a rewritable CD disposed on the carrier vehicle. The CD recorder, the CD wiper and the CD reader are arrangedat intervals along the circumferential direction of the physical isolation device. The carrier vehicle is provided with a motor for driving the rewritable CD to rotate. The rewritable CD is located on the carrier vehicle. The CD recorder, the CD wiper and the CD reader each include a mounting cavity and a passage for the carrier vehicle to pass through. A CD driver is arranged in the mounting cavity. A through hole for the cooperation of the CD driver and the rewritable CD is arranged under the mounting cavity. The carrier vehicle successively passes the passage of the CD recorder, the passage of the CD reader, and the passage of the CD wiper to realize one data transmission. Because it is not necessary to repeatedly take the CD and put the CD and the CD driver does not need to start therotation of the rewritable CD, the data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of physical isolation devices, in particular to a physical isolation device and a data transmission method. Background technique [0002] In order to ensure the safe exchange of data between the intranet and the extranet, the safest way is to physically separate the intranet server and the extranet server by setting up physical isolation devices. [0003] Current data storage media mainly include optical discs, magnetic disks, magnetic tapes, etc. As a stable storage carrier, optical discs are often used to store important data. The existing physical isolation device generally burns the data stored in the internal network server into a blank optical disc, and then stores the data stored in the burned optical disc to the external network server for transmission. After the data transfer is completed, the optical disc Recycling and destruction, this method is costly, and the number of blank discs is limited, a...

Problems solved by technology

The existing physical isolation device generally burns the data stored in the internal network server into a blank optical disc, and then stores the data stored in the burned optical disc to the external network server for transmission. After the data transfer is completed, the optical disc Recycling and destroying, the cost of this method is high, and the number of blank discs is limited, it is easy to appear that the blank discs are not enough, and it is necessary to manually add discs

There are also some physical isolation devices that use rewritable optical discs. Due to their data rewritable performance, rewritable optical discs can erase the data on them after transferring data, and rewritable optical discs can be reused thousands of times, thus The cost of data transfer is reduced, but it is still necessary to set up the manipulator to realize the capture and release of the disk, and the use efficiency is low
