[0035] Current smart management cabinets use UHF RFID technology to monitor items in real time, identifying item information by reading electronic tags inside the cabinet. However, due to the strong penetration and wide coverage of RFID signals, there is a serious problem of cross-reading between layers in the multi-layered cabinet 1. That is, the reader 3 of one layer may misread the signal of a tag from another layer, causing the system to be unable to accurately determine the actual location of the tag.

[0036] Based on this, this application proposes an intelligent management cabinet that solves the problem of existing intelligent management cabinets being prone to misreading signals from other layer tags by setting up wiring channels.

[0037] The following is combined with Figures 1-6 This invention describes the intelligent management cabinet.

[0038] Please refer to the intelligent management cabinet proposed in the embodiments of this application. Figures 1 to 2 The intelligent management cabinet includes: cabinet body 1, main controller, sub-controllers, shielding cover 7, and main wiring harness (not shown in the figure). Cabinet body 1 includes several storage cabinets arranged vertically. The main controller is connected to the top of cabinet body 1. At least one sub-controller is installed on the inner side wall of each storage cabinet, and the sub-controller is equipped with a connector. Shielding cover 7 is connected to one of the left and right side walls of the storage cabinet, and a wiring channel is formed between shielding cover 7 and the side wall of cabinet body 1. The storage cabinet is equipped with a through hole that connects the adjacent upper and lower wiring channels. Shielding cover 7 is equipped with plug-in terminals, and the connector is plugged into the terminals. The main wiring harness passes through the wiring channel and through holes to connect the main controller to each terminal. The main controller communicates with the sub-controllers of each storage cabinet through the main wiring harness.

[0039] According to the embodiments of this application, each storage cabinet is equipped with a shielding cover 7, which forms a wiring channel with the side wall of the cabinet 1. This can isolate RFID signals from adjacent layers, reduce the possibility of cross-reading, and connect to the main wiring harness through the wiring terminals on the shielding cover 7, thereby improving the stability of signal transmission, avoiding the possibility of signal leakage from the wiring channel and cable terminal connection, and improving the identification accuracy of the intelligent management cabinet.

[0040] Cabinet 1 consists of multiple storage cabinets arranged vertically, each forming an independent storage unit. The main controller, serving as the system's control hub, is mounted on the top of cabinet 1 and is responsible for overall coordination and data aggregation. In some embodiments, the main controller includes a reader / writer 3; in others, it further includes a locking control plate 4. At least one sub-controller is installed on the inner side wall of each storage cabinet. These sub-controllers are connected to the wiring terminals on the shielding cover 7 via connectors, forming a distributed control network. In some embodiments, the sub-controller corresponding to the reader / writer 3 is a reader / writer antenna 5, and the sub-controller corresponding to the locking control plate 4 is an electric lock 6.

[0041] A closed wiring channel is formed between the shielding cover 7 and the side wall of the cabinet 1. This design not only provides neat wiring space but, more importantly, effectively blocks RFID signal interference between adjacent layers through the shielding effect of the shielding cover 7. The plug-in terminals on the shielding cover 7 adopt a standardized interface design, allowing for quick plugging and unplugging of the sub-controller connectors, greatly simplifying the installation and maintenance process. The wiring channels of adjacent storage cabinets are interconnected through cable guide holes, enabling the main wiring harness to run through the entire cabinet 1 and achieving stable communication between the main controller and the sub-controllers on each layer.

[0042] The shielding cover 7 can be a metal shielding cover. The electromagnetic shielding environment formed by the metal shielding cover can effectively absorb or reflect RFID signals, minimizing signal interference. Of course, in addition to metal shielding covers, the shielding cover 7 can also be a shielding cover made of other materials with shielding functions.

[0043] In one possible embodiment of this application, please refer to Figure 3 The intelligent management cabinet is equipped with shielding cotton 8, which is placed inside the wiring channel or around the shielding cover 7 to enhance the electromagnetic shielding performance of the system. The shielding cotton 8 can be made of conductive foam or metal fiber composite material.

[0044] In actual installation, the shielding cotton 8 can be arranged in two ways: the first is to surround it inside the wiring channel; the second is to cover the outer surface of the shielding cover 7, forming a composite structure of metal cover and flexible shielding material. This dual arrangement method can be flexibly selected according to the needs of the actual application scenario to achieve the best shielding effect.

[0045] According to one embodiment of this application, please refer to Figure 4 and Figure 5 It includes an upper fixing member 11 and a lower fixing member 12. The upper fixing member 11 is connected to the top wall of the storage cabinet, and the lower fixing member 12 is connected to the bottom wall of the storage cabinet. The first end of the shielding cover 7 is fixedly connected to the upper fixing member 11, and the second end of the shielding cover 7 is fixedly connected to the lower fixing member 12. Part of the shielding cotton 8 is provided at the connection between the shielding cover 7 and the upper fixing member 11, and part of the shielding cotton 8 is provided at the connection between the shielding cover 7 and the lower fixing member 12.

[0046] Understandably, the coordinated design of the upper fixing member 11 and the lower fixing member 12 achieves a stable installation of the shielding cover 7 and continuity of electromagnetic shielding. Specifically, the upper fixing member 11 is fixedly connected to the top wall of the storage cabinet, while the lower fixing member 12 is fixedly connected to the bottom wall of the storage cabinet. Both ends of the shielding cover 7 are connected to these two fixing members respectively, forming a complete vertical shielding structure. This method of upper and lower fixing not only enhances the stability of the overall structure but also ensures a tight fit between the shielding cover 7 and the cabinet body 1.

[0047] Part of the shielding cotton 8 is set at the connection between the shielding cover plate 7 and the upper fixing member 11, and another part is set at the connection between the shielding cover plate 7 and the lower fixing member 12. The shielding cotton 8 effectively fills the tiny gaps that may exist at the fixed connection, preventing electromagnetic waves from leaking through these gaps. The elastic properties of the shielding cotton 8 can also compensate for the tolerances generated during manufacturing and installation, ensuring tight contact between the components.

[0048] According to one embodiment of this application, the upper fixing member 11 is fully welded to the top wall of the storage cabinet, and the lower fixing member 12 is fully welded to the bottom wall of the storage cabinet.

[0049] The upper fixing component 11 is firmly connected to the top wall of the storage cabinet using a full welding process, and the lower fixing component 12 is similarly fixed to the bottom wall of the storage cabinet using the same full welding process. The full welding process ensures a continuous and complete metal connection between the fixing components and the cabinet body 1, providing not only extremely high structural strength but also excellent electrical continuity. Compared to spot welding or bolt connections, this connection method completely eliminates minute gaps at the connection points, effectively preventing electromagnetic wave leakage.

[0050] According to one embodiment of this application, please refer to Figure 1 , Figure 2 and Figure 6 The main controller includes a reader / writer 3 and a lock control board 4. The sub-controller includes a reader / writer antenna 5 and an electric lock 6. The plug-in terminal block includes an RF terminal 92 and a lock control terminal 94. The connector includes an RF connector 91 and a lock control connector 93. The reader / writer 3 is connected to the RF terminal 92 via the main wiring harness. The RF terminal 92 is connected to the RF connector 91. The RF connector 91 is connected to the reader / writer antenna 5. The lock control board 4 is connected to the lock control terminal 94 via the main wiring harness. The lock control terminal 94 is connected to the lock control connector 93. The lock control connector 93 is connected to the electric lock 6.

[0051] In this embodiment, the main controller includes a reader / writer 3 and a lock control board 4. The reader / writer 3 is responsible for handling the transmission and reception of RFID signals, while the lock control board 4 specifically manages the opening and closing control of the cabinet door 2. Each sub-controller is equipped with a reader / writer antenna 5 and an electric lock 6, which are connected to the main controller through dedicated interfaces. Specifically, the plug-in terminals are subdivided into radio frequency terminals 92 and lock control terminals 94, and the corresponding connectors are also divided into radio frequency connectors 91 and lock control connectors 93.

[0052] In actual wiring, reader 3 is connected to RF terminal 92 via main wiring harness, and then connected to reader antenna 5 via RF connector 91; lock control board 4 is also connected to lock control terminal 94 via main wiring harness, and finally controls electric lock 6 via lock control connector 93. This hierarchical connection method ensures the reliability of signal transmission, while facilitating fault diagnosis and maintenance. RF signals and control signals are transmitted through independent channels, effectively avoiding signal crosstalk.

[0053] According to one embodiment of this application, a cabinet door 2 is included, which is rotatably connected to a storage cabinet. An electric lock 6 is used to control the opening and closing of the cabinet door 2. The cabinet door 2 is rotatably connected to the frame of the storage cabinet via a hinge mechanism, forming an openable and closable storage space. The electric lock 6, as an actuator, precisely controls the opening and closing state of the cabinet door 2 by receiving control signals from a lock control board 4.

[0054] According to one embodiment of this application, one of the connector and the terminal block is a wire hole, and the other is a plug-in type threaded connector.

[0055] According to one embodiment of this application, the connector is a metal connector and the terminal block is a metal socket-type threaded connector.

[0056] According to one embodiment of this application, the storage cabinet has an opening for storing and retrieving items, and a shielding cover 7 is disposed on the side of the storage cabinet near the opening.

[0057] Understandably, in related technologies, wiring such as radio frequency lines and lock control lines from the back of the management cabinet increases the overall size of the intelligent management cabinet 1, reduces assembly efficiency, and lowers warehouse space utilization. Furthermore, maintenance requires moving the cabinet 1, which is very inconvenient. This application solves the space waste problem caused by rear wiring in traditional intelligent management cabinets by placing the shielding cover 7 on the side of the storage cabinet near the access opening, significantly improving warehouse space utilization. In addition, maintenance personnel can complete all maintenance work at the access position without moving the cabinet 1, improving ease of use.

[0058] According to one embodiment of this application, an outer shielding cover is also included, which covers the outside of the shielding cover 7. The outer shielding cover and the side wall of the storage cabinet form a closed space to shield the mating area of ​​the wiring terminals and connectors.

[0059] The outer shielding cover covers the outside of the original shielding cover 7, forming a completely enclosed electromagnetic shielding space together with the side wall of the storage cabinet. This completely encloses the mating area of ​​the wiring terminals and connectors, thus achieving shielding at the connection point of the connectors plugged into the wiring terminals.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
