Problems solved by technology

[0006] Therefore, the first technical problem to be solved by the present invention is to overcome the fact that in the prior art, the transfer processing equipment (ferry unit) used between networks of different security levels still needs to be connected with networks of different security levels, so that it cannot really achieve Physical isolation between networks of different security levels, technical defects of low security, thus providing a transit processing device that can truly realize physical isolation between networks of different security levels
[0007] The second technical problem to be solved by the present invention is to overcome the fact that the transfer equipment (ferry unit) used in the prior art for data transmission devices between networks of different security levels still needs to be connected with networks of different security levels, so that it cannot really achieve Physical isolation between networks of different security levels, technical defects of low security, thus providing a network data transmission device that can truly realize physical isolation between networks of different security levels
[0008] The third technical problem to be solved by the present invention is to overcome the fact that the transfer processing method used in the prior art between networks with different security levels still needs to be connected to networks with different security levels, so that it is impossible to truly achieve the transfer between networks with different security levels. Physical isolation, low security technical defects, thus providing a data transfer processing method that can truly realize physical isolation between networks with different security levels

Embodiment 1

[0063] like figure 1 As shown, this embodiment provides a transfer device for realizing one-way secure data transmission between the first network 3 and the second network 4, including a transfer station 1, a first movement device and a second movement device, so The first moving device is used to collect blank optical discs, transport the blank optical discs to the recording optical drive group 5 in the first network area, and transport the optical discs recorded by the recording optical drive group 5 to the transfer station 1, so that The second movement device is used to collect the recorded optical disc located in the transfer station 1, and transport the recorded optical disc to the read-only optical drive group 6 in the second network area for the read-only optical drive group 6 Complete data reading and downloading.

[0064]When the above-mentioned transfer equipment provided by this embodiment is used for data transmission between the first network 3 and the second ne...

Embodiment 2

[0074] Such as figure 2 As shown, this embodiment provides a network data transmission device for one-way secure data transmission between the first network 3 and the second network 4, including the first network area and the second network area, the first network The area has a recording CD-ROM drive group 5, the second network area has a read-only CD-ROM drive group 6, the first network area is used to burn a blank disc, and the second network area is used to receive the burned disc and read data , also includes a transfer device, the transfer device includes at least one transfer station 1, used to collect blank optical discs, transport the blank optical discs to the recording optical drive group 5, and burn the optical disc after passing through the recording optical drive group 5 Transported to the first movement device of the transfer station 1, and for collecting the recorded optical disc located on the transfer station 1, and transporting the recorded optical disc to ...

Embodiment 3

[0084] Such as image 3 As shown, this embodiment provides a data transfer method for realizing one-way secure data transmission between the first network 3 and the second network 4. The data transfer method uses the transfer device described in Embodiment 1, including The following steps are carried out in sequence:

[0085] (1) The first movement device collects the blank disc located in the disc barrel 8. It should be noted that there may be multiple disc barrels 8, and at least one blank disc is placed in each disc barrel 8. The first movement device Collect blank discs from different disc barrels 8 as needed during movement. In this embodiment, the first moving device is a manipulator 2, and the manipulator 2 has a disc grabber 10 to grab blank discs through the disc grabber 10. CD;

[0086] (2) The first moving device runs the collected blank disc to the recording drive group 5 in the first network area, that is, the manipulator 2 realizes the transportation of the bla...

Abstract

The invention provides a relay apparatus, a data transmission device, a data relay method and a data transmission method. The relay apparatus can be used for transmitting data between networks different in security level, and comprises a transfer station, a first moving device and a second moving device; in use, the first moving device is used for collecting blank discs firstly, and then moving the blank discs to a burning optical drive in a first network region, and finally moving the discs burned by the burning optical drive to the transfer station; the second moving device is used for collecting the burned discs at the transfer station at this moment and moving the burned discs to a read-only optical drive in a second network region so that the read-only optical drive is capable of completing data reading and downloading. In this process, the first network and the second network are physically isolated from each other completely, so that the technical detect that the relay apparatus needs to be connected with the first network at one moment and needs to be connected with the second network at another moment in the prior art; as the first network and the second network are physically isolated from each other completely, the safety of data transmission is very high.

Description

technical field [0001] The invention relates to a transfer device applied to data transmission between networks with different security levels, a network data transmission device with the transfer device, a data transfer method using the transfer device, and a data transfer method with the data transfer method, belonging to data transmission technology field. Background technique [0002] In data communication, data transmission between networks with different security levels is often required, for example, data transmission between internal network and external network, or data transmission between public network and private network, or confidential network and non-confidential network data transfer between. In order to realize and ensure the security of the network data exchange process, the safest way is to separate the networks of different security levels to realize "physical isolation" between networks of different security levels.
