Detailed Implementation
[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0034] refer to Figs. 1 to 3 .
[0035] The present invention provides an intelligent cabinet with height adjustment function, which mainly includes a cabinet body 10, a main control unit 11, a sealed door 26, a temperature adjustment unit (not shown in the figure, which may be a combination of a semiconductor cooling chip and a PTC heater integrated into the cabinet wall), and a control screen 29.
[0036] The main interior of cabinet 10 is a medicine storage space, with a first assembly cavity 18 and a second assembly cavity 17 on its left and right sides, respectively. The storage space contains multiple horizontally arranged support plates 15 for holding medicines. The first support plate 15 is a fixed layer, and each support plate 15 above it can be independently raised and lowered. Specifically, in the first assembly cavity 18 on the right, a first main drive structure 37 is installed corresponding to each movable support plate 15. This structure includes a rotary drive motor 21, a drive gear 20 driven by the motor, and a gear rack 19 fixed to the right side of the support plate 15, with the drive gear 20 meshing with the gear rack 19. In the second assembly cavity 17 on the left, a first engaging drive structure 38 is installed corresponding to each movable support plate 15, which includes a telescopic drive motor 23 and a telescopic arm 22 driven by the motor, with the top of the telescopic arm 22 connected to the left side of the support plate 15. The main control unit 11 can control the rotary drive motor 21 and the telescopic drive motor 23 to work synchronously and in coordination. Through gear and rack transmission and the pushing / retracting of the telescopic arm, the support plate 15 can be raised, lowered and locked smoothly and accurately.
[0037] To achieve intelligent identification, identification components 16 are installed at the top of the inner cavity of the cabinet 10 and at the bottom of each movable shelf 15. The identification components 16 include a centrally located high-definition panoramic camera 12, a nearby 3D depth camera 13, and multispectral ring LED lights 14 arranged around them. The top identification component 16 is responsible for overall monitoring and measuring the size of the medicines placed in the cabinet, while the bottom identification component 16 is used to scan the top information of the medicines on the lower shelf. In addition, a shelf camera 35 is installed on the upper surface of each shelf 15 near the door to capture the side information of the medicines on that shelf. The surface of each shelf 15 is divided into grid-like shelf areas, and a thin-film sensor 36 is integrated under each area to sense the weight and pressure distribution of the medicines in that area, enabling precise positioning and quantity verification.
[0038] On the right side of the exterior of cabinet 10, there is a pre-entry structure 39 and a temporary storage structure 40. The pre-entry structure 39 is a small, independent cabinet with a door 31. The top of its interior is equipped with an identification component 16, and the bottom has a pull-out sliding support plate 32. Staff can place the medicines to be stored here first. After closing the door 31, the system automatically completes information identification and size measurement. The temporary storage structure 40 consists of an electric push rod 34 and a temporary support plate 33. When batch operations or temporary placement of medicines are required, the electric push rod 34 can be controlled via the control panel 29 to push out the temporary support plate 33, which can then be used as a work surface.
[0039] The top front of cabinet 10 is equipped with a low-pressure buzzer 25 and a multi-color LED indicator strip 24 to convey system status (such as running, alarm, successful operation, etc.) through sound and light. Next to it is a lifting projection structure 41, consisting of a lifting drive motor 28 and a projector 27. The projector 27 can be lowered when needed to project information such as operation guidance arrows and medicine location boxes onto the temporary support plate 33 or inside the cabinet. The sealed door 26 is equipped with a control panel 29, a fingerprint reader 43, and an iris reader 42, which together constitute a high-level security access control and interactive interface.
[0040] Working principle:
[0041] When storing medications, staff first open the sealed door 26 via fingerprint or iris verification. The medication is then placed into the temporary storage cavity 30 of the pre-entered structure 39. After closing the door 31, the internal identification component 16 activates, acquiring the medication's visual information, barcode, and precise three-dimensional dimensions, and uploading the data to the main control unit 11. Based on the medication dimensions, the current height of each shelf 15, and the load conditions, the main control unit 11 uses a built-in algorithm to calculate the optimal storage layer and the target height adjustment required for that layer. Subsequently, the system guides staff to open the main cabinet door via indicator lights or projection.
[0042] When staff retrieve the medicine and place it into the main cabinet, the identification component 16 at the top can re-verify the medicine. The main control unit 11 controls the first main drive structure 37 and the first cooperating drive structure 38 of the target shelf and all shelves above it to work together to automatically adjust to a suitable space. After the staff places the medicine in the designated position, the thin-film sensor 36 on the shelf senses the weight change, verifies it with the visual recognition result, confirms successful storage, and updates the inventory data.
[0043] When retrieving medication, staff select the medication on the control panel 29. The system can indicate the location of the target medication on the receiving plate 15 and its specific area via flashing indicator lights 24 or projection from the projector 27. After medication retrieval, the weight change detected by the thin-film sensor 36 is re-verified with visual recognition to ensure accurate medication retrieval and automatically optimize the space below.
[0044] This intelligent cabinet adopts a multi-level closed-loop control working mode, with the main control unit as the core, integrating perception, decision-making, execution, and feedback to realize intelligent management of the entire process of drug storage.
[0045] The core workflow is broken down as follows:
[0046] 1. Drug storage process:
[0047] Step 1: Identity Verification → Operators verify their identity using a fingerprint / iris scanner.
[0048] Step 2: Pre-entry and recognition → The medicine is placed in the pre-entry structure, and a high-definition camera and a 3D depth camera acquire visual information and precise dimensions of the medicine.
[0049] Step 3: Intelligent Planning → The main control unit calculates the optimal storage location based on the size of the medicine, current inventory, and space layout.
[0050] Step 4: Space Adaptive Adjustment → The system automatically drives the corresponding support plate to adjust its height to create a suitable space.
[0051] Step 5: Guided Placement → Guide the operator to place the medicine in the designated location using indicator lights, projections, etc.
[0052] Step 6: Verification and Confirmation → The thin-film sensor and identification component verify the drug information and update the inventory database.
[0053] 2. Medication Removal Procedure:
[0054] Step 1: Identity Verification and Inquiry → After verifying their identity, operators can inquire about the required medicines through the control screen.
[0055] Step 2: Precise Positioning Guidance → The system accurately indicates the location of the medicine through indicator lights and a projector.
[0056] Step 3: Drug Retrieval and Verification → After the drug is retrieved, the thin-film sensor monitors the weight change and verifies it against the inventory record.
[0057] Step 4: Space Optimization → The system automatically adjusts the height of the lower support plate to optimize storage space.
[0058] 3. Environmental maintenance procedures:
[0059] Temperature sensors monitor the environment inside the cabinet in real time.
[0060] The main control unit controls the temperature regulation unit to work according to the set parameters.
[0061] A closed-loop control system is formed to maintain a constant temperature environment.
[0062] The system features of this implementation method are as follows:
[0063] 1. Multimodal perception fusion: Data fusion from multiple sensors, including visual recognition, 3D size measurement, weight perception, and environmental monitoring, to ensure comprehensive and accurate information.
[0064] 2. Intelligent decision optimization: Based on algorithm-based spatial layout planning and inventory management, storage space utilization is maximized.
[0065] 3. Closed-loop precision control: A complete closed loop is formed from perception to execution, with feedback verification for each action to ensure accurate and reliable operation.
[0066] 4. User-friendly human-computer interaction: Provides intuitive operation guidance through various means such as lighting, sound, projection, and touch screen.
[0067] 5. Full process traceability: All operations are recorded in detail, meeting medical audit requirements.
[0068] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
