Description

Method and device for ferrying optical disk

Technical Field

The invention relates to the field of mechanical control, in particular to a method and a device for realizing the ferry of an optical disk among elements through a mechanical arm.

Background

With the development of information technology, the application of the internet has penetrated into various fields of social life, information security and network security have become a subject of the development of human society, personal privacy, company intellectual property and trade secrets, and protection of government and national secrets are more and more emphasized, and in order to protect information security and network security, a dedicated network for physical isolation is usually established to prevent external intrusion; however, in operation, a large amount of information and data needs to be exported from a physically isolated intranet to an extranet, and how to solve the security problem in the process of exporting the internal information data to the extranet becomes an important issue of information and network security.

The data Pump technology is a Pump technology proposed by myogh. Although the data pump technology realizes the unidirectional transmission of data from inside to outside, the protocol transmission is bidirectional, so that if the protocol is hidden by Trojan horse, the reverse transmission is difficult to be eliminated by using the protocol.

The principle of the optical fiber unidirectional transmission technology that optical signals are taken as the unidirectional transmission technology is mainly characterized in that the safe and reliable unidirectional transmission is realized by utilizing the characteristic that the optical signals are transmitted and received in one optical fiber in an irreversible manner. The main method uses a unidirectional optical fiber card to realize optical transmission and reception to achieve the purpose of unidirectional transmission, and a transmitting end and a receiving end are respectively connected with a PC (personal computer) and a USB (universal serial bus) interface to realize point-to-point information unidirectional introduction. The technology can solve the information exchange between the outer network magnetic medium and the inner network magnetic medium, effectively prevents ferry trojans, but still needs to use the inner network magnetic medium, and the risk of secret leakage is still lost in the management and control of the inner network magnetic medium.

The physical isolation transmission technology is a data transmission technology with higher safety, and is characterized in that communication data transmission between data transmission networks can be avoided through physical isolation, and further attack and damage of Trojan horse or virus programs on the data storage network through a communication data transmission channel are avoided. Specifically, the physical isolation transmission technology is used for data transmission by means of an intermediate memory between data storage networks, and the transmission mode can ensure that data information between the data networks is transmitted in a unidirectional manner, and the transmission mode is more effective in isolation of trojans or computer viruses in the existing data transmission technology. However, the transmission method also causes a complicated process for performing physical isolation, and the physical isolation depends on the mutual matching of the components, so the physical isolation often has the problems of large occupied space caused by difficult matching of the components, or wasted space between the components.

Example 1

As shown in fig. 4 to 5, the present embodiment provides a method for ferrying an optical disc, which is applied to an optical disc ferrying device, where the device includes a mechanical arm, a first optical drive, a second optical drive, a loading bucket, and an optical disc recycling box, where the first optical drive, the second optical drive, the loading bucket, and the optical disc recycling box are stacked one on another, and the optical disc recycling box is disposed at the bottom layer of the stack; the first optical drive comprises a first optical drive tray for placing an optical disc, the second optical drive comprises a second optical drive tray for placing the optical disc, the first optical drive tray, the second optical drive tray and the feeding barrel can move in the horizontal direction and are initially stored in specific positions, and the first optical drive tray, the second optical drive tray, the feeding barrel and the optical disc recovery box are located on the same axis at the moving positions; the mechanical arm is arranged on the axis and can do linear motion along the axis, and the method comprises the following steps:

In an optional implementation manner, the step of completing the ferry of the target optical disc among the first optical drive, the second optical drive, the loading bucket, and the optical disc recycling bin by the mechanical arm includes:

The ferry task is specifically that the mechanical arm is used for executing the movement of the optical disc among different positions, a first optical drive tray, a second optical drive tray and a feeding barrel in the device are set to be in a storage state initially, and the movement range of the mechanical arm is not influenced in the storage state.

Furthermore, the first optical drive tray, the second optical drive tray and the feeding barrel are accommodated in the same side, and the first optical drive tray, the second optical drive tray, the feeding barrel and the optical disc recovery box are in a stacked design, so that the single-side space of the device can be effectively utilized. The first optical drive tray and the second optical drive tray correspond to the first optical drive and the second optical drive respectively, so that the first optical drive, the second optical drive and the feeding barrel in the storage state are further arranged on the same side and are positioned right above or right below each other, and the problem that the physical space is wasted is further solved.

When a ferry task is received, the method controls the mechanical arm to execute the ferry task in three stages, wherein the feeding stage aims to ferry the optical disk from a feeding barrel to a first optical drive for recording and reading of the first optical drive; the ferrying stage aims to ferry the optical disk from the first optical drive to the second optical drive for recording and reading by the second optical drive, and essentially ferries the network or database information corresponding to the first optical drive to the network or database corresponding to the second optical drive through the optical disk; the recycling stage is set to solve the recycling problem of the optical disc, because the optical disc is only used as a data storage medium in the ferry process in the invention, the optical disc can be recycled, and the used optical disc is placed into the optical disc recycling box by the mechanical arm to complete the recycling of the storage medium.

In an optional implementation manner, the first optical drive, the second optical drive, the loading bucket, and the optical disc recycling box are stacked in the stated order, a blank optical disc is stored in the loading bucket, and the step of completing the ferry of the target optical disc among the first optical drive, the second optical drive, the loading bucket, and the optical disc recycling box by the mechanical arm includes:

s211: ejecting a second CD-ROM tray after the data CD is read;

s212: the optical disk which is read is grabbed by the mechanical arm;

When the first optical drive, the second optical drive, the feeding barrel and the optical disc recovery box are mutually stacked according to the sequence, the mechanical arm has an optimal ferrying scheme. Aiming at the ferry task, the mechanical arm does not need to be restored to the initial position after each time of grabbing or placing, and when the optical disk needs to be ferred to the second optical disk drive by the first optical disk drive, the mechanical arm does not need to be restored to the initial position; the robotic arm does not have to return to the initial position from the time the disc is loaded onto the tray of the second drive to the time it is loaded into the disc retrieval cassette. Based on the above-mentioned optimization, the moving path of the robot is simplified and shortened, but it should be noted that the robot is not in a stationary state when steps S210 and S213 are performed, and the robot should be lifted or moved as small as possible and properly to avoid affecting the storage of the first optical drive, the second optical drive or the loading bucket according to the above-mentioned conditions.
