Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) technology, specifically an intelligent digital item management system applicable to mobile scenarios. Background Technology

[0002] Existing products for solving material management problems are primarily geared towards enterprises, addressing large-scale logistics and warehousing management. For large-scale scenarios like supermarkets, the use of tags and large-size identification devices is essential. However, in outdoor travel scenarios, the diversity of item types necessitates tags that meet requirements for fit and high sensitivity. Active electronic products also require anti-shielding and stability. For flexible products like clothing, tags need good resistance to stretching, bending, and torsion. Simultaneously, precise digital management and control for small suitcases or backpacks is also particularly important.

[0003] In the prior art, a Chinese patent discloses an intelligent digital item management system that combines software and hardware (authorization announcement number CN220983902U). This patented technology optimizes the storage and management methods through the combination of software and hardware. The overall usage method is simple and easy to learn. The client application displays the information of the items to be managed more clearly and centrally, realizing intelligent Internet of Things personal material management, improving the efficiency and speed of storing and managing items during travel, and making travel more convenient.

[0004] However, the aforementioned patent document's mobile scenario item management solution has the following drawbacks: when an item is inside a carrier (car) and is in a moving state, the continuous vibration and positional changes of the carrier will cause the signal between the reader and the item tag to be extremely unstable, resulting in serious inaccuracy of positioning information. The system cannot effectively distinguish between the carrier's movement and the item's actual displacement, making it difficult to directly apply to mobile environments.

[0005] Therefore, an intelligent digital item management system applicable to mobile scenarios is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent digital item management system applicable to mobile scenarios, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An intelligent digital item management system applicable to mobile scenarios includes a cloud management platform, a user interaction terminal, a fixed monitoring network, and a portable management terminal. The fixed monitoring network consists of at least three fixed reference anchors, which are fixedly installed inside the mobile carrier.

[0015] Please see Figures 1-4 A smart digital item management system applicable to mobile scenarios includes a cloud management platform 4, a user interaction terminal 5, a fixed monitoring network, and a portable management terminal 3. The fixed monitoring network consists of at least three fixed reference anchor points 2, which are fixedly installed in the internal space of the mobile carrier. The three fixed reference anchor points 2 establish a stable coordinate reference system for the entire internal space of the carrier (car). Even if the carrier is moving or vibrating, it can be used as a reference for accurate measurement. This method can continuously track all items with UWB tags and achieve 24-hour unattended monitoring.

[0016] The mobile carrier contains items with UBW item tags 1 attached to them. The fixed reference anchor point 2 includes a first housing 201, a UWB first positioning chip 202, an inertial measurement unit 203, and a microprocessor 204 disposed within the first housing 201. The inertial measurement unit 203 inside the carrier senses the vibration, tilt, acceleration, and other motion states of the carriage, providing data to distinguish between the movement of the carrier and the movement of the items.

[0017] The portable management terminal 3 includes a second housing, inside which are housed a UWB second positioning chip, a multimodal recognition module, and a display unit. The portable management terminal 3 also includes a positioning module, which is a BeiDou dual-mode positioning chip. The portable management terminal 3 can perform on-site operations such as manual inspection, item retrieval, and data viewing, and can collaborate with a fixed network to improve its positioning accuracy. The portable management terminal 3 also includes a wireless communication module, through which it communicates with the cloud management platform 4. The first UWB positioning chip 202 of the fixed reference anchor point 2 is communicatively connected to the second UWB positioning chip of the portable management terminal 3. A magnetic suction plate 205 is provided on the first housing 201 of the fixed reference anchor point 2. The first UWB positioning chip 202 is the core of high-precision positioning. On the one hand, it communicates with the item tag 1 to locate the item, and on the other hand, it communicates with the portable terminal 3 to provide it with a positioning reference.

[0018] The multimodal identification module includes an RFID identification unit, a visual identification unit (identifying appearance, barcodes, and QR codes), and an NFC identification unit (for near-field, high-security user identification). The second housing of the portable management terminal 3 is equipped with a snap-on interface for connecting the battery life module. By setting up the snap-on interface, the battery life anxiety problem of mobile devices during long-term field operations is solved. The snap-on design ensures reliable connection and convenient disassembly and assembly, ensuring that the equipment can work continuously and stably, and enhancing the reliability of the system.

[0019] Example 1: The mobile carrier is a refrigerated transport truck, and the system needs to monitor and manage the vaccine boxes transported in the truck throughout the entire process.

[0020] like Figure 1 As shown, the fixed monitoring network is set up as follows: Inside the truck compartment, the magnetic plates 205 on the back of the three fixed reference anchor points 2 are used to attach them to the top, lower left and lower right positions inside the compartment, respectively. These three anchor points form a triangular UWB positioning reference network. Item identification: Each vaccine box is an item, and an active UWB item tag is affixed to its outer surface.

[0021] Portable Management Terminal 3 Configuration: The administrator is equipped with a portable management terminal 3, which has a built-in UWB second positioning chip, a Beidou dual-mode positioning chip as a positioning module, and a multi-modal recognition module that integrates an RFID identification unit, a 2-megapixel visual recognition unit and an NFC identification unit. The terminal has a snap-on interface on the side, which can be connected to a portable battery with a capacity of 5000mAh, i.e., a power supply module.

[0022] Cloud connectivity: The terminal supports 5G network and maintains signal connection with the cloud management platform 4 of remote data center through its internal wireless communication module. Managers can access the system through the Web terminal of the office computer user interaction terminal 5 or the APP terminal of the mobile user interaction terminal 5.

[0023] Automated monitoring phase: During vehicle operation, the fixed monitoring network inside the carriage continues to operate. Three fixed reference anchor points 2 communicate with the UWB item tags 1 on each vaccine box through their UWB first positioning chip 202 to understand and calculate the precise position of each box in real time. The inertial measurement unit 203 senses the vibration and attitude changes of the carriage. The microprocessor 204 performs preliminary data processing and packages the item position and attitude data in the carriage through the communication module of the anchor points. The data is then sent to the cloud management platform 4 through the vehicle gateway. Once the cloud analysis detects that the position of a vaccine box is abnormally offset by more than 20 centimeters, or detects violent vibrations such as sudden braking, an early warning will be issued immediately through the administrator's mobile APP.

[0024] Precise search phase: like Figure 3 As shown in the left figure, when the vehicle arrives at the transfer station, the administrator enters the carriage with a portable management terminal 3. The terminal immediately detects the strong UWB signal emitted by the fixed reference anchor point 2 and automatically enters the network calibration mode. At this time, the terminal's UWB second positioning chip is synchronized with the fixed network, and its own positioning accuracy is improved from the meter level of Beidou to the centimeter level of UWB. When the administrator uses the terminal's camera to scan the vaccine box, the terminal screen not only displays the item information, but also records its precise two-dimensional coordinates X and Y in the carriage. This location data is in the same coordinate system as the data of the fixed network, realizing data fusion.

[0025] When the administrator gets off the vehicle to inspect other goods in the station, the portable management terminal 3 loses the UWB signal of the fixed network and automatically switches to independent working mode. It relies on the built-in Beidou dual-mode positioning chip to perform meter-level positioning and quickly scans the goods through the RFID identification unit. All data is uploaded to the cloud through the 5G network. like Figure 3 As shown in the right figure, in areas with weak 5G signals, the terminal can temporarily form a network with other nearby terminals via Bluetooth to relay data. The snap-on interface connection of the battery module ensures continuous operation for more than 8 hours.

[0026] The above process effectively solves the problems of poor accuracy and low automation in the management of items in mobile vibration environments by constructing a dynamic and static collaborative system consisting of a fixed monitoring network and a portable management terminal interconnected via UWB. The fixed network serves as a static reference, enabling 24-hour automated high-precision monitoring and early warning; the portable terminal can obtain centimeter-level positioning calibration within the fixed network and can work independently outside the network, thus realizing full-process, highly reliable intelligent management of items in mobile scenarios, from automatic monitoring to precise inspection.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
