Description

Technical Field

[0001] This utility model relates to the field of optical disc offline storage management technology, and more specifically, to an offline optical disc library cabinet with an intelligent access system. Background Technology

[0002] An optical disc library is a network sharing device for optical discs equipped with an automatic disc changing mechanism (robotic arm). An optical disc library generally consists of three parts: a disc rack for holding optical discs, an automatic disc changing mechanism (robotic arm), and drives. In recent years, due to the significant increase in the storage capacity of a single optical disc, optical disc libraries have become increasingly advantageous in terms of price and performance compared to common storage devices such as disk arrays and tape libraries. As a storage device, optical disc libraries have begun to be used in various fields, such as image storage of bank documents, data storage in insurance institutions, and all other high-capacity nearline data storage applications.

[0003] Traditional Blu-ray discs, after being burned onto Blu-ray storage devices, are typically stored offline using disc cases containing multiple discs. The entire set is then stored offline, with each case labeled with an RFID or barcode for easy tracking and management. However, if these disc cases are stored in a simple offline storage cabinet, and many cases are stored within the cabinet, manual visual identification and location of each case are required. A barcode scanner is then used to scan the labels on the cases to determine if they have been stored or removed. This lack of intelligent access is time-consuming, labor-intensive, and prone to errors. While offline storage cabinets equipped with robotic arms offer automated access, they significantly increase costs, and the increased mechanical movement raises the likelihood of equipment failure. Utility Model Content

[0004] To overcome the problems of existing offline storage systems that require manual visual identification of specific CD / DVD cases and scanning of labels on the cases to determine whether they are in or out of storage, which are time-consuming, labor-intensive, and prone to errors, and where adding robotic arms would significantly increase costs, this invention provides an offline CD / DVD storage system with an intelligent retrieval system. The system includes a main cabinet and several auxiliary cabinets, with the auxiliary cabinets sequentially connected to one side of the main cabinet. Both the main and auxiliary cabinets have internal CD / DVD storage compartments, each containing several vertically arranged trays, each holding several CD / DVD cases.

[0005] An intelligent access mechanism is provided between the main offline cabinet and the auxiliary offline cabinet. The intelligent access mechanism includes an RFID tag, an RFID indicator light, and an RFID antenna. The RFID tag and RFID indicator light are both located on the optical disc tray, and the RFID antenna is installed on the layer tray assembly below the optical disc tray.

[0006] The main cabinet of the offline cabinet is equipped with an electrical control top box on its top. An integrated display unit is installed on the outside of the electrical control top box. An RFID antenna multiplexer and an RFID read / write drive controller are installed inside the electrical control top box and connected to the RFID antenna.

[0007] Employing the principle of high-frequency RFID antenna sensing, the system can sense the location and tag information of multiple disc boxes in real time and drive the LEDs on the tags of the target disc boxes to flash. This overcomes the pain point of manual searching required in simple offline optical disc libraries, while also greatly reducing costs and increasing system reliability. In addition, the offline optical disc library adopts a multi-channel parallel design of high-frequency RFID antennas, which can realize centralized management of multiple disc libraries, greatly simplifying the entire intelligent offline management system and facilitating the expansion and upgrade management of the offline optical disc library.

[0008] In a preferred embodiment, the main cabinet of the offline cabinet is hinged to a cabinet door on the front, and an integrated display unit is provided on the top of the front of the cabinet door. The integrated display unit is electrically connected to the RFID read / write drive controller.

[0009] In a preferred embodiment, a combination lock is provided at the connection between the cabinet door and the offline main cabinet, and a transparent panel is provided at the bottom of the front of the cabinet door.

[0010] In a preferred embodiment, the shelf assembly includes a shelf frame and optical disc holder partitions. A plurality of optical disc holder partitions are inserted into the surface of the shelf frame, and a placement space for placing optical discs is formed between two adjacent optical disc holder partitions.

[0011] The tray assembly is designed with several disc tray partitions and a rear baffle. The internal space formed by the disc tray partitions, the rear baffle, and the front baffle is just the accommodating space for the disc trays, which serves to store and limit the disc trays. By moving the position of the hanging hole of the limiting hole on the front baffle, the height position of the front baffle can be adjusted, thereby enabling the disc trays to be stored and retrieved.

[0012] In a preferred embodiment, a rear baffle is installed on the back of the shelf, and a detachable front baffle is provided on the front of the shelf.

[0013] In a preferred embodiment, the electrical control top box is provided with a control box shelf inside, on which an RFID antenna multiplexer, a power module and an RFID read / write drive controller are installed.

[0014] In a preferred embodiment, the all-in-one display is electrically connected to an RFID antenna multiplexer via an RFID read / write drive controller. The RFID antenna multiplexer is electrically connected to RFID antennas located inside several offline cabinets. The RFID antennas are connected to RFID tag signals.

[0015] The CD case is mainly used to store multiple CDs, serving as a sealed, dustproof, and damage-proof storage solution. The RFID tag has unique identification information and comes with an LED indicator. It is placed in an appropriate position on the CD case to facilitate RFID antenna sensing and operation.

[0016] In a preferred embodiment, the bottom of the main offline cabinet and several auxiliary offline cabinets are all equipped with casters.

[0017] In a preferred embodiment, the inner walls of the main offline cabinet and several auxiliary offline cabinets are provided with an insulating coating.

[0018] When a CD / DVD drive with an RFID tag is correctly placed into the offline CD / DVD library, the RFID antenna instantly detects the tag information and feeds it back to the system software via the RFID antenna multiplexer, read / write drive, and integrated display. The software records and archives this information. When a specific CD / DVD drive needs to be located, the user simply enters its information on the interface. The system software automatically locates and positions the drive, triggering the LED on the RFID tag to flash via the integrated display, read / write drive, RFID antenna multiplexer, and RFID antenna. The user can quickly find the drive by following the flashing LED. When the user removes the CD / DVD drive, the system immediately detects this and records its removal information.

[0019] Beneficial effects:

[0020] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0021] (1) The high-frequency RFID antenna sensing principle can sense the location and tag information of multiple disc boxes in real time, and drive the LED of the tag on the target disc box to flash. This not only overcomes the pain point of manual search required for simple offline optical disc libraries, but also greatly reduces costs and increases the reliability of the system. At the same time, the offline optical disc library adopts a multi-channel parallel design of high-frequency RFID antennas, which can realize the centralized management of multiple disc libraries, greatly simplifying the entire intelligent offline management system and facilitating the expansion and upgrade management of the offline optical disc library.

[0022] (2) The CD case is mainly used for storing multiple CDs, and plays a role in sealing and preventing dust and damage. The RFID tag has a unique identification information and has its own LED indicator. It is placed in an appropriate position on the CD case so that the RFID antenna can sense and drive it.

[0023] (3) When the CD case with the RFID tag is correctly placed into the offline CD library, the RFID antenna can immediately sense the RFID tag information and feed the information back to the system software through the path of RFID antenna multiplexer-read / write driver-display all-in-one machine. The software records the information and archives it. When it is necessary to query a target CD case, just enter the information of the target CD case on the interface. The system software can automatically help to find and locate the target CD case and drive the LED light of the RFID tag on the target CD case to flash through the display all-in-one machine-read / write driver-RFID antenna multiplexer-RFID antenna. The user can quickly find the target CD case based on the signal of the flashing LED light. When the user takes out the target CD case, the system will immediately sense that the CD case has been taken out and record its out-of-store information.

[0024] (4) The tray assembly is designed with several disc tray partitions and rear baffles. The internal space formed by the disc tray partitions, rear baffles and front baffles is just the accommodating space for the disc trays, which serves to store and limit the disc trays.

[0035] This implementation method utilizes the high-frequency RFID antenna sensing principle to detect the location and tag information of multiple disc drives in real time, and can drive the LEDs on the tags of the target disc drives to flash. This overcomes the pain point of manual searching required in simple offline optical disc libraries, while significantly reducing costs and increasing system reliability. Furthermore, the offline optical disc library employs a multi-channel parallel design with high-frequency RFID antennas, enabling centralized management of multiple disc drives, greatly simplifying the entire intelligent offline management system and facilitating the expansion and upgrade management of the offline optical disc library. The specific implementation method is as follows:

[0036] like Figures 1 to 7As shown, an offline optical disc library cabinet with an intelligent access system includes a main offline cabinet 1 and several auxiliary offline cabinets 2. The auxiliary offline cabinets 2 are sequentially connected to one side of the main offline cabinet 1. Both the main offline cabinet 1 and the auxiliary offline cabinets 2 have optical disc storage compartments inside. Each optical disc storage compartment includes several layer trays 9 arranged vertically, and each layer tray 9 holds several optical disc boxes 4. An intelligent access mechanism is provided between the main offline cabinet 1 and the auxiliary offline cabinets 2. The intelligent access mechanism includes RFID tags 18, RFID indicator lights 19, and RFID antennas 21. The RFID tags 18 and RFID indicator lights 19 are both set on the optical disc boxes 4. The RFID antennas 21 are installed on the layer trays 9 below the optical disc boxes 4. An electronic control top box 3 is set on the top of the main offline cabinet 1. An integrated display 6 is set on the outside of the electronic control top box 3. An RFID antenna multiplexer 13 connected to the RFID antennas 21 and an RFID read / write drive controller 15 are set inside the electronic control top box 3. Employing the principle of high-frequency RFID antenna sensing, the system can sense the location and tag information of multiple optical disc boxes 4 in real time, and drive the RFID indicator light of the RFID tag 18 on the target disc box to flash. This overcomes the pain point of manual searching required in simple offline optical disc libraries, while greatly reducing costs and increasing system reliability. In addition, the offline optical disc library adopts a multi-channel parallel design of high-frequency RFID antennas, which can realize centralized management of multiple disc libraries, greatly simplifying the entire intelligent offline management system and facilitating the expansion and upgrade management of the offline optical disc library.

[0037] Specifically, the main offline cabinet 1 has a door 5 hinged to its front, and a display unit 6 is installed on the top of the front of the door 5. The display unit 6 is electrically connected to the RFID read / write drive controller 15. The auxiliary offline cabinet 2 has a similar structure to the main offline cabinet 1, and its surface is only equipped with a door 5. After opening the door 5, the CD box 4 can be accessed.

[0038] Specifically, a combination lock 10 is installed at the connection between cabinet door 5 and the main offline cabinet 1, and a transparent panel 7 is installed at the bottom of the front of cabinet door 5. The combination lock 10 can improve the security of the offline CD library, and the transparent panel 7 can be used to view the CD box 4 at the bottom of the main offline cabinet 1. At the same time, a transparent panel is also installed in the middle of the upper cabinet door of the secondary offline cabinet 2. The transparent panel 7 is made of glass or transparent acrylic sheet.

[0039] Specifically, the tray assembly 9 includes a shelf frame 16 and disc drive spacers 20. Several disc drive spacers 20 are inserted into the surface of the shelf frame 16, forming a space between adjacent disc drive spacers 20 for placing disc drives 4. The tray assembly 9 is designed with several disc drive spacers 20 and a rear baffle 17. The internal space formed by the disc drive spacers 20, the rear baffle 17, and the front baffle 8 is precisely the accommodating space for the disc drives 4, serving to store and limit the disc drives 4. The shelf frame 16 has multiple equidistant slots for the disc drive spacers 20, allowing adjustment of two disc drive spacers 20 to accommodate disc drives 4 of different sizes.

[0040] Specifically, a rear baffle 17 is installed on the back of the shelf 16, and a detachable front baffle 8 is provided on the front of the shelf 16. The rear baffle 17 can limit the rear of the optical disc cartridge 4. The front baffle 8 has two connected hanging holes, one high and one low, on both sides. In use, the front baffle 8 can be hung in the lower hole by fixing bolts to limit the optical disc cartridge 4. By moving the hanging position of the hanging hole on the front baffle 8, the height position of the front baffle 8 can be adjusted to realize the storage and retrieval of the optical disc cartridge.

[0041] Specifically, the electrical control top box 3 has a control box shelf 12 inside, on which an RFID antenna multiplexer 13, a power module 14, and an RFID read / write drive controller 15 are installed. The control box shelf 12 supports the RFID antenna multiplexer 13, the power module 14, and the RFID read / write drive controller 15. At the same time, each of the other offline cabinets 2 has an RFID antenna multiplexer 13 on its top. These RFID antenna multiplexers 13 are all connected to the RFID read / write drive controller 15 and are powered by the power module 14.

[0042] Specifically, the all-in-one display 6 is electrically connected to the RFID antenna multiplexer 13 via the RFID read / write drive controller 15. The RFID antenna multiplexer 13 is electrically connected to the RFID antennas 21 located inside several offline cabinets 2. The RFID antennas 21 are connected to the RFID tags 18 via signals. The CD / DVD case 4 is mainly used for storing multiple CD / DVDs, providing a sealed, dustproof, and damage-proof storage function. The RFID tags 18 carry unique identification information and have built-in LED indicators. They are placed in appropriate positions on the CD / DVD case 4 to facilitate sensing and activation by the RFID antennas 21.

[0043] Specifically, the RFID antenna 21 is placed on the shelf 16. There should be no metal material at the bottom and top of the RFID antenna 21, otherwise it will affect the electromagnetic field of the antenna. At the same time, when the shelf 16 is made of metal, the placement position of the RFID antenna 21 should be designed to avoid gaps. The RFID antenna 21 can also be designed above the CD case 4. The corresponding RFID tag 18 can be attached to the upper edge of the CD case 4, or other positions extending from it. The RFID tag 18 should be perpendicular to the RFID antenna 21 and maintain a sufficient distance from the shelf 16 to avoid the metal part of the shelf 16 interfering with the RFID antenna 21's sensing of the RFID tag 18.

[0044] Specifically, the bottom of the main offline cabinet 1 and several auxiliary offline cabinets 2 are all equipped with casters 11. The casters 11 facilitate the movement of the main offline cabinet 1 and several auxiliary offline cabinets 2.

[0045] Specifically, the inner walls of the main offline cabinet 1 and several auxiliary offline cabinets 2 are all coated with an insulating layer. This insulating coating improves the insulation performance of the main offline cabinet 1 and the auxiliary offline cabinets 2, thus enhancing safety during use.

[0046] A method for accessing an offline optical disc library cabinet with an intelligent access system includes the following steps:

[0047] When it is necessary to save to a CD

[0048] Step 1: Place the CD into the CD case with the RFID tag and correctly place it into the offline CD library;

[0049] Step two: The RFID antenna in the offline CD library can instantly sense RFID tag information;

[0050] Step 3: The RFID antenna multiplexer receives the information sensed by the RFID antenna and transmits it to the display all-in-one machine under the action of the RFID read / write drive controller;

[0051] Step four: The all-in-one machine records this information and archives it for management.

[0052] When you need to remove the disc

[0053] Step 1: Enter the information of the target CD case on the all-in-one display interface;

[0054] Step 2: The display unit transmits signals via the path of RFID reader / writer driver controller - RFID antenna multiplexer - RFID antenna;

[0055] Step 3: The RFID antenna quickly identifies the information of the target CD case and drives the RFID indicator light of the corresponding CD case RFID tag to flash.

[0056] Step four: The user removes the target CD case and records its outbound information.

[0057] Working Principle: Utilizing high-frequency RFID antenna sensing, the system can detect the location and tag information of multiple disc holders in real time, and drive the LEDs on the tags of the target disc holders to flash. This overcomes the pain point of manual searching required in simple offline disc libraries, while significantly reducing costs and increasing system reliability. Furthermore, the offline disc library employs a multi-channel parallel design of high-frequency RFID antennas, enabling centralized management of multiple disc libraries, greatly simplifying the entire intelligent offline management system and facilitating the expansion and upgrade management of the offline disc library. The disc holders are primarily used for storing multiple discs, providing sealed, dustproof, and damage-proof storage. RFID tags carry unique identification information and have built-in LED indicators. Placed in appropriate positions on the disc holders, they facilitate RFID antenna sensing and activation. When a disc holder with an RFID tag is correctly placed into the offline disc library, the RFID antenna instantly senses the RFID tag information and feeds this information back to the system software via the path of RFID antenna multiplexer - read / write driver - display all-in-one machine. The software records and archives this information. When a specific CD / DVD case needs to be located, the user simply enters its information on the interface. The system software automatically locates and positions the case, and activates the LED on the RFID tag of the case via a multi-function display unit, read / write driver, RFID antenna multiplexer, and RFID antenna. The user can quickly locate the case by following the LED flashing signal. When the user removes the case, the system immediately detects this and records its removal information. The tray assembly is designed with several compartment partitions and a rear baffle. The internal space formed by the compartment partitions, rear baffle, and front baffle serves as the storage space for the CD / DVD cases, effectively limiting their placement. By adjusting the position of the mounting holes on the front baffle, the height of the front baffle can be adjusted, allowing for the storage and retrieval of CD / DVD cases.

[0058] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
