Description

Technical Field

[0001] This utility model relates to an equipment cabinet, and more particularly to an RFID equipment cabinet. Background Technology

[0002] In recent years, RFID equipment cabinets have been widely used in warehousing and logistics, medical equipment management, fire emergency equipment storage, and military equipment control. This equipment achieves intelligent management by attaching electronic tags to the surface of tools through a built-in radio frequency identification system. During use, operators must authenticate their identity to open the cabinet door. When tools are taken out or returned, the RFID readers distributed across multiple layers inside the cabinet automatically scan the electronic tags, updating the inventory data to the back-end management system in real time. In fire station applications, firefighters manually locate needed equipment such as respirators and hydraulic forceps after swiping their cards for verification; medical institutions use the system to manage surgical instrument packs, allowing medical staff to open the cabinet door and retrieve the recorded instrument combinations.

[0003] However, existing RFID equipment cabinets have significant shortcomings in practical applications. The system only has a passive recording function and cannot actively dispatch tools based on a preset task list. When performing emergency tasks, users still need to manually search for the target tools after opening the cabinet door, which can easily lead to the misalignment of adjacent tools and disrupt the initial storage order. The misplacement of tools caused by frequent searching will lead to errors in subsequent inventory checks, especially in emergency scenarios with poor lighting or tight deadlines, which can easily result in the safety hazard of missing or mistaking tools. In addition, existing equipment lacks intelligent recommendation functions and cannot automatically generate the optimal tool combination based on the task type, making it difficult to meet the core requirements of modern equipment management for rapid response and precise dispatch. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an RFID equipment cabinet that can display equipment for users based on the equipment information entered in the electronic tags.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an RFID equipment cabinet, comprising a cabinet for placing equipment, a cabinet door for opening and closing the cabinet and a reader for reading the content of electronic tags, a storage area and a retrieval area within the cabinet, the storage area having several equipment boxes for placing equipment and grippers for gripping the equipment boxes, a lifting platform for carrying the equipment boxes within the cabinet, the grippers gripping the equipment boxes onto the lifting platform, and the lifting platform being movable from the storage area to the retrieval area.

[0006] The beneficial effects of this invention are as follows: The layered storage and retrieval areas enable automated equipment storage and retrieval, significantly improving the efficiency and accuracy of equipment management. The lower storage area maximizes space utilization for high-density storage, while the lifting platform vertically transports the equipment to the upper retrieval area, conforming to ergonomic principles and avoiding intersections between the storage and retrieval routes. As a preferred embodiment, the lifting platform can employ a guide rail and servo motor drive system, with guide rails and roller assemblies on both sides. An encoder precisely controls the lifting stroke, ensuring the stability of the equipment box during vertical movement. The gripper can utilize a multi-degree-of-freedom robotic arm structure, with an end effector designed as an adaptive gripper. Pressure sensor feedback enables reliable gripping of equipment boxes of different sizes, solving the problem of poor compatibility with traditional fixed clamps.

[0007] Furthermore, the retrieval area is equipped with a linkage processor for identifying the camera installed in the equipment box.

[0008] A dual-mode visual recognition system implements a dual verification mechanism for equipment management. During the retrieval phase, the camera performs feature matching on the equipment on the lifting platform. When a discrepancy is detected between the equipment box label information and the characteristics of the internal items, the linked processor immediately terminates the operation and issues an alarm. During the return phase, the visual recognition system automatically determines whether the equipment has been returned intact through item contour recognition and feature comparison technology. As a preferred approach, the camera can employ a multispectral imaging module, with a ring-shaped supplementary lighting strip installed at the top of the retrieval area. This combination of light sources with different wavelengths eliminates surface reflection interference from the equipment. The processor can integrate an image recognition algorithm module to quickly compare multi-dimensional features such as the equipment's size, color, and surface texture.

[0009] Furthermore, the storage area is equipped with storage slots corresponding to the number of equipment boxes, and each storage slot and the corresponding equipment box is equipped with an electronic tag.

[0010] Zero-error management of equipment archiving is achieved through a two-way verification mechanism using electronic tags. An RFID reading coil is embedded in the bottom of each storage slot, forming a closed-loop verification system with the electronic tag on the bottom of the equipment box. When a handler places an equipment box, the system automatically compares the tagging information between the storage slot and the equipment box; if misalignment is detected, a correction procedure is immediately triggered. As a preferred approach, the storage slots can be designed in a honeycomb structure, with each slot equipped with an independent position sensor and indicator light. A green indicator light triggers when the equipment box is correctly placed, while a red indicator light flashes and an audible and visual alarm is activated when the box is misplaced. The electronic tags can use encrypted NFC chips to store the equipment's unique identification code and maintenance records, ensuring data security.

[0011] Furthermore, the lifting platform is provided with several placement slots that are adapted to the equipment box, and the placement slots are arranged sequentially on the lifting platform.

[0012] The standardized positioning structure enhances the operability and identification efficiency of equipment storage and retrieval. The placement slots employ a modular design, with cushioning material and guide ramps on the inner walls to ensure the equipment boxes maintain a stable posture during lifting and lowering. As a preferred option, the placement slots can be equipped with an electromagnetic locking mechanism, which automatically activates the electromagnetic attraction device when the equipment box is placed inside, preventing displacement during transportation. Each placement slot has a weighing sensor at its bottom, which compares the weight with standard values ​​in the system database in real time; an automatic verification process is triggered when an abnormal weight is detected. The slot surface is coated with an anti-static coating and equipped with drainage channels to adapt to equipment storage needs under different environmental conditions.

[0013] Furthermore, a projection device is provided in the retrieval area, which is used to remind the user whether the equipment has been put into the correct equipment box when returning the equipment.

[0014] An intelligent error correction mechanism based on human-machine collaboration is implemented through an augmented reality interaction system. The projection device integrates a laser positioning module, which can dynamically project the outline and status indicators of the equipment box onto the retrieval table. As a preferred method, the projection system can use DLP digital light processing technology to project high-contrast prompts directly onto the surface of the equipment box. When misplacement is detected, an arrow can be displayed in real time to guide the correct storage location. The system is linked to a pressure sensor, which automatically projects a flashing warning frame in the corresponding area when the equipment box is removed and not returned within a set time. The projection module is equipped with an ambient light adaptive adjustment function to ensure the visibility of the prompts under different lighting conditions. Attached Figure Description

[0021] An embodiment of this utility model provides an RFID equipment cabinet, such as... Figure 1-6As shown: The cabinet includes a cabinet body 1, with a hinged door 11 on the front for opening and closing. An RFID reader 12 is installed inside the door 11 for reading electronic tag information. The interior of the cabinet body 1 is divided into a lower storage area 13 and an upper retrieval area 14 by a partition. The storage area 13 has multiple storage slots 133 arranged in a matrix, each containing an equipment box 131. A first electronic tag 1331 is embedded in the bottom of each equipment box 131, and a second electronic tag 1332 is located at the corresponding position on the bottom of each storage slot 133. A mechanical gripper 132, movable in three-dimensional space, is installed at the top of the storage area 13, with an electromagnetic chuck at its end for gripping the equipment boxes 131. A lifting platform 15 is installed in the middle of the storage area 13, with multiple linearly arranged placement slots 151 on its surface, each slot 151 matching the size of the equipment box 131.

[0022] A high-definition camera 21 is installed on the top of the inner wall of the retrieval area 14. The camera 21 is connected to a linkage processor 22 with a built-in image recognition algorithm. A projection device 23 is embedded in the front side wall of the retrieval area 14, and the projection direction of the projection device 23 is towards the lifting platform 15. The lifting platform 15 is connected to the drive motor through a guide rail mechanism and can be vertically raised and lowered between the storage area 13 and the retrieval area 14.

[0023] When equipment needs to be retrieved, the user brings the corresponding electronic tag close to the reader 12. After the reader 12 reads the tag information, the control system converts it into corresponding electronic identification information 1331 and controls the gripper 132 to move to the corresponding storage slot 133. By comparing the first electronic identification 1331 with the second electronic identification 1332, the gripping position is confirmed, and the equipment box 131 is gripped into the placement slot 151 of the lifting platform 15. After the lifting platform 15 rises to the retrieval area 14, the camera 21 captures an image of the items inside the equipment box 131 and compares it with a preset database to confirm the correctness of the gripping. If an identification error is found, the linkage processor 22 controls the projection device 23 to project warning information.

[0024] When returning equipment, the user places it into the equipment box 131 on the lifting platform 15. The camera 21 identifies the equipment's features and binds them to the equipment box 131's serial number. After confirmation, the lifting platform 15 descends to the storage area 13, and the grabber 132 accurately returns the equipment box 131 to its correct position based on the second electronic identifier 1332 of the storage slot 133. If the camera 21 detects a mismatch between the equipment and the equipment box 131 during return, the projection device 23 will project a prompt light spot to indicate the correct placement.

[0025] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
