Cassette automatic login device of intelligent compact disc off-line intensive cabinet

Abstract

The invention discloses a cassette automatic login device of an intelligent compact disc off-line intensive cabinet, comprising a cabinet body and a compact disc drawer arranged in the cabinet body, wherein a plurality of compact disc cassettes are distributed in the compact disc drawer; a radio frequency reading device is arranged near a push-pull inlet and outlet of each compact disc drawer on the cabinet body; and a radio frequency label is arranged on each compact disc cassette, corresponding to the radio frequency reading device. The cassette automatic login device of the intelligent compact disc off-line intensive cabinet solves the problem of move-in-and-out identification of the compact disc cassette of the intelligent compact disc off-line intensive cabinet, improves the operatingefficiency of a near-line and off-line system integration solution, improves the degree of automation of the system, lowers the human input and administration cost, and simultaneously reduces the probability of human misoperation and the possibility of malignant replacement.

Description

technical field [0001] The invention relates to an automatic registration device for cassettes of an off-line dense cabinet for intelligent optical discs. Background technique [0002] The digitization process on a global scale has led to an explosive demand for information storage. Among the large amount of stored digital information, 80% are content that is used infrequently but has long-term storage. This information is ideally suited for storage on optical discs. Modern optical discs are standardized digital recording media whose physical dimensions are fixed. The capacity of optical discs is continuously expanding with the advancement of technology, and the speed of reading and writing is also increasing. For example, the capacity of each disc of BD Blu-ray Disc has reached 50GB, and is developing to 100GB. In the information system, there will be more and more CDs filled with important information to produce. An efficient means of managing these discs is to use a di...

AI Technical Summary

Problems solved by technology

[0009] Shortcoming 1: the disc magazine radio frequency (RFID) label 11 of the disc magazine 3 of original structure is only arranged on the side of disc magazine 3 (see figure 2 )

When needing to insert or take out CD cassette 3 every time like this, all will repeat this operation like this, and efficiency is low, and speed is slow, and error rate is high

[0010] Disadvantage 2: There are hidden dangers in data storage security performance in the process of moving in and out of the disc box 3 in the smart disc offline intensive cabinet

Relying on the existing position sensor 5, it can only be determined whether there is a disc cartridge 3 in the specific storage compartment 4 of the smart disc offline dense cabinet 1, but it cannot be accurately and uniquely determined which disc is placed in the specific storage compartment 4 Cassette 3

Therefore, it is still unavoidable that some human errors or vicious disc cartridge 3 packet loss problems appear
