一种基于信息物理集成的光盘自动标识系统

An integrated cyber-physical system for automatic identification of massive discs

光盘能够进行可靠、低成本地离线长期数据存储,当对保存的海量数据进行查询时,需要能够快速逻辑定位到查询结果,并且能够确定所属光盘的物理位置,进行数据读取。这要求光盘在信息及物理世界中拥有唯一的标识,从而方便、可信地统一管理海量数据。本文设计一种批量光盘自动标识系统,它集成普通商用的刻录机、打印机和摄像头,实现批量光盘的自动化物理标签打印和逻辑标识刻录。考虑到每个部件都具有内部独立的时序控制、特定的存取接口。本研究设计并开发了定制化机械结构,以及全局软件调度机制,统一协调物理和逻辑控制。实验结果表明,单套系统能够一次连续地标识200张光盘,平均每张2 min。

Optical discs can reliably preserve massive data for long-term in low-cost.When querying these accumulative data,it is necessary to quickly obtain the query results,and to seek the physical location of the corresponding optical disc.To this end,it demands each disc have a unique identifier in both the cyber and physical worlds,make massive data be managed effectively,conveniently,and credibly.This paper designs a batch-disc automatic identification system,which integrates common optical disc recorders,printers,and cameras,automatically to print physical label and to burn logical identification on each disc.Consider that each commodity component has its own internal independent timing control and a specific external interface.This study designed and developed a customized mechanical structure,as well as a global software scheduling mechanism to coordinate physical behavior and logical control.The experimental results show that the system can continuously identify 200 discs at once,averaging 2 minutes per disc.
