Container type optical storage data center control system

Abstract

The invention discloses a container type optical storage data center control system which comprises an upper computer, a central control PLC, an equipment PLC and a servo controller which are in communication connection in sequence. The container comprises a container body, a CD-ROM drive wall, a storage unit and an action executing mechanism. The action executing mechanism is electrically connected with the servo controller; the upper computer sends a control instruction to the central control PLC, the equipment PLC and the servo controller in sequence; and the servo controller controls the action executing mechanism to finish the actions of storing, taking, transporting, transferring and loading the compact disc in the storage unit according to a preset track according to the control instruction. According to the invention, the reading and writing process of the optical disc in the container can be highly automatically controlled, the control process has high flexibility and practicability, and the man-machine interaction requirement can be met.

Description

technical field [0001] The present invention relates to the technical field of optical storage, and more specifically relates to a control system of a container-type optical storage data center. Background technique [0002] Optical storage is a mass data storage method that uses optical discs as storage media. It has the advantages of low energy consumption, mobility, and long data storage period. It is very suitable for storing data with low access frequency and long-term storage. [0003] Existing storage technologies mainly include three storage methods: hard disk for magnetic storage, U disk (including SD card) for semiconductor storage, and optical disk for optical storage. However, magnetic storage is the same as semiconductor storage, the information will disappear when it is hit by a strong electromagnetic field, and the information can be rewritten at any time; only optical storage can be read-only, and cannot be rewritten after being written once. Therefore, opti...

AI Technical Summary

Problems solved by technology

[0004] At present, optical disc library has been gradually used in many fields, such as bank note image storage, insurance agency data storage, etc.; Transfer, storage capacity cannot be easily expanded, data read and write speed is still slow, etc.

The position of the traditional array optical disc library is fixed, it cannot be easily moved, and the data read and write speed is slow; the storage capacity of the rotating cage optical disc library is small, and the capacity cannot be expanded according to the actual storage requirements
