Description

Technical Field

[0001] This invention relates to the field of logistics positioning, and more specifically, to a logistics positioning and tracking system. Background Technology

[0002] The assembly of products and their parts in the segmented workshop is mainly distributed via pallets. Therefore, according to the requirements of lean production theory, a complete logistics management system needs to be built during the manufacturing and circulation of assembled products and their parts. This system uses pallets as the basic unit for logistics tracking and monitoring, organizing production and various management tasks, and establishing a comprehensive palletized management mechanism. In the past, logistics tracking management used two separate systems for locating and reading the tags attached to the monitored objects. This often resulted in inconsistencies when integrating location information with tag status information on the production and logistics management sides. This reduced the real-time performance of logistics monitoring and also decreased the accuracy of monitoring information.

[0003] Therefore, how to accurately track and locate a large number of dynamically moving objects, and ensure that the acquired location information is synchronized with the status information recorded by the tags, is an urgent problem to be solved in the construction of ship sections. Summary of the Invention

[0004] The purpose of this invention is to propose a logistics positioning and tracking system that can accurately track and locate the positions of a large number of items and logistics equipment, while also having the ability to remotely store information from electronic tags.

[0005] To achieve the above objectives, the present invention provides a logistics positioning and tracking system, comprising:

[0006] An electronic tag, which is an integrated positioning tag and active identification module, is installed on the item that needs to be tracked;

[0007] The acquisition module includes a UWB positioning base station and an active identification module acquisition unit integrated in the UWB positioning base station. The UWB positioning base station is used to acquire the RSSI value of the positioning tag, and the active identification module acquisition unit is used to acquire the identity information of the active identification module.

[0008] The positioning engine module calculates the location information of the electronic tag based on the RSSI value of the positioning tag according to the positioning algorithm, and associates the location information with the identity information of the active identification module;

[0009] The active identification module identification module obtains the associated location information and the identity information of the active identification module, and authenticates the identity information of the active identification module through the identification resolution node to parse out the item identification information, so that the location information is associated with the item identification information;

[0010] The logistics tracking and monitoring module acquires and stores the associated location information and item identification information, and provides the associated location information and item identification information to the management system.

[0011] In an optional configuration, the management system includes a production management system and a logistics management system. The production management system is used to initiate material allocation instructions, and the logistics management system is used to initiate logistics allocation instructions.

[0012] In an optional configuration, the encoding of the positioning tag is written into the storage of the active identification module, registered with the identification resolution node, obtains security authentication from the identification resolution node, and synchronizes the authentication information with the national top-level node of the identification resolution.

[0013] In an optional solution, the NB-IoT communication module of the positioning tag is embedded with an industrial internet identifier. The NB-IoT communication module periodically sends parsing requests to query the address and operation information of the positioning terminal through the identifier resolution system, thereby realizing remote positioning terminal information reading and configuration management.

[0014] In the optional solution, the item identification information includes material information, pallet information, and vehicle information.

[0015] In an optional configuration, the active identification module's identification module registers its identity information with the identification resolution node and obtains a security authentication certificate; the identification resolution node synchronizes the active identification module's identity information to the national top-level identification resolution node; when the electronic tag is read, it transmits the active identification module's identity information to the identification resolution node, performs security authentication at the identification resolution node, parses the active identification module's identity information to extract the item identification information, and then feeds the parsing result back to the active identification module's identification module.

[0016] In an optional embodiment, the positioning system further includes a display module, which is based on the production management system and the logistics management system and is used to display the production status, current material status, and logistics execution status.

[0017] In an optional configuration, the location tracking system is deployed based on a 5G standalone private network system.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention combines positioning tags with active identification functions, enabling accurate tracking and positioning of a large number of objects and logistics equipment. It also has the ability to remotely store information from electronic tags. While the electronic tag obtains its location, it also obtains the identification information stored in the active identification for identification authentication. Then, it obtains the identification registration information from the identification resolution node, realizing the simultaneous acquisition of tag positioning and identification-related information, improving the efficiency of acquiring information from monitored objects, and integrating with the management system to achieve intelligent production control and logistics scheduling.

[0020] The present invention has other features and advantages, which will be apparent from or will be set forth in detail in the accompanying drawings and the following detailed description, which together serve to explain the particular principles of the invention. Attached Figure Description

[0021] The above and other objects, features and advantages of the present invention will become more apparent from the more detailed description of exemplary embodiments of the invention in conjunction with the accompanying drawings.

[0022] Figure 1 A flowchart of a logistics location tracking system according to an embodiment of the present invention is shown. Detailed Implementation

[0023] The invention will now be described in more detail. While preferred embodiments are provided, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0024] Reference Figure 1 An embodiment of the present invention provides a logistics positioning and tracking system, comprising:

[0025] Electronic tags are integrated positioning tags and active identification modules. Electronic tags are installed on items that need to be tracked.

[0026] The acquisition module includes a UWB positioning base station and an active identification module acquisition unit integrated in the UWB positioning base station. The UWB positioning base station is used to acquire the RSSI value of the positioning tag, and the active identification module acquisition unit is used to acquire the identity information of the active identification module.

[0027] The positioning engine module calculates the location information of the electronic tag based on the RSSI value of the positioning tag according to the positioning algorithm, and associates the location information with the identity information of the active identification module.

[0028] The active identification module identification module obtains the associated location information and the identity information of the active identification module. It authenticates the identity information of the active identification module through the identification resolution node to parse out the item identification information and associate the location information with the item identification information.

[0029] The logistics tracking and monitoring module acquires and stores associated location information and item identification information, and provides associated location information and item identification information to the management system.

[0030] This embodiment utilizes the logistics tracking system to perform identity verification and read / write of object status information simultaneously with the location data collection of electronic tags installed on pallets, logistics vehicles, intermediate products, and components. Object status information includes item identification information and electronic tag information. Item identification information includes material information, pallet information, and vehicle information. This embodiment combines positioning tags with active tagging functionality, enabling accurate tracking and positioning of a large number of objects and logistics equipment. It also possesses remote information storage capabilities for electronic tags. While acquiring location data, the electronic tag simultaneously retrieves the tagging information stored in the active tagging database for identification authentication, and then obtains tag registration information from the tagging resolution node. This allows for simultaneous tag positioning and tag-related information acquisition, improving the efficiency of monitoring object information acquisition and integrating with the management system to achieve intelligent production control and logistics scheduling.

[0031] Specifically, the electronic tag combines a positioning tag with an active identification module. A customized module is embedded within the positioning tag device. The module, built-in security chip, and IoT card serve as the identification carriers for the active identification. Identification at each stage of the device is stored in the security chip embedded in the customized NB-IoT module. The device uses the module to achieve active identification registration, identification resolution, and trusted data collection. The positioning tag code is written into the active identification storage. Security authentication is performed simultaneously when registering with the identification resolution node, and the authentication information is synchronized to the national top-level node of the identification resolution system to ensure secure identification authentication across regions and enterprises. This solves the problem of synchronizing tag positioning and identity recognition with the dynamic information recording of monitored objects. The active identification module binds the positioning tag code to the identification information of items (logistics equipment, intermediate products, materials, etc.). Through active identification security authentication processing, it simultaneously identifies the location and identity of the object bound to the tag, obtains relevant real-time dynamic information of the tag-bound object, and transmits this information in real-time to the logistics tracking and monitoring module deployed on the MEC edge computing server. The logistics tracking and monitoring module acquires and stores the associated location information and item identification information, and provides the associated location information and item identification information to the management system. The management system includes a production management system and a logistics management system. The production management system is used to initiate material allocation instructions, and the logistics management system is used to initiate logistics allocation instructions. This supports intelligent production control and logistics allocation, improving the level of intelligent management in ship section construction.

[0032] In this embodiment, the electronic tag integrates with an Industrial Internet identifier, combining the original UWB positioning tag with a security chip. The Industrial Internet identifier is bound to the identity of each positioning tag, and the integrated security chip provides active identification capabilities. Utilizing the tamper-proof nature of the identifier, the identity information is encrypted and stored, and the positioning tag ID is stored in the active identification storage. The NB-IoT communication module of the positioning tag embeds the Industrial Internet identifier, registering and associating information such as address, positioning tag ID, and operation commands. The NB-IoT communication module periodically sends parsing requests, querying the address and operation information of each positioning terminal through the identifier resolution system, enabling remote positioning terminal information reading, configuration management, and other functions.

[0033] The location tag's encoding is written to the active identification module's storage, registered with the identification resolution node, obtains security authentication from the identification resolution node, and synchronizes authentication information with the national top-level identification resolution node. The UWB positioning base station integrates an active identification module acquisition unit, enabling it to simultaneously collect the positioning signal emitted by the location tag and the active identification information. Based on the positioning signal strength, it calculates the location tag's RSSI value and sends this value, along with the active identification module's identity information, to the positioning engine module. The positioning engine module, based on the location tag's RSSI value and its positioning algorithm, calculates the electronic tag's location information and associates this location information with the active identification's identity information.

[0034] The active identification module first registers the identification information with the identification resolution node. The identification resolution node issues a security certificate for the registered active identification and synchronizes its security authentication information to the national top-level node of the identification resolution system. When an active identification is read, the active identification information undergoes identity authentication at the identification resolution node. After authentication, the identification information is parsed, and the parsing result is fed back to the active identification module. After successful authentication, the identification registration information is obtained. Using the identification registration information as an index, real-time dynamic information of the identification (such as current workstation, quantity, etc.) is shared among various application systems. The identification resolution node authenticates the identity information of the active identification module to parse the item identification information, associates the location information with the item identification information, and realizes the positioning and identification of the object attached to the electronic tag.

[0035] The location tracking system in this embodiment is deployed based on a 5G standalone private network system. This system comprises three components: a 5G CPE, 5G base stations, and a 5G core network. Logistics equipment and application terminals connect to the 5G CPE via Wi-Fi and access the 5G private network system. The 5G private network connects to the edge computing server (MEC) via a switch, enabling access to MEC application services. The macro base stations of the private network provide wide-area coverage and seamless connectivity, while micro base stations and Wi-Fi provide services in hotspot areas to increase network capacity. Equipment within the segmented workshop transmits data via Wi-Fi; when network traffic is high, it can also access the network through indoor private network base stations. When activities are conducted in the material storage area outside the workshop, data interaction is primarily conducted through the macro base stations of the private network. The 5G private network and the 5G public network are completely isolated. Within the 5G private network, base stations and production equipment communicate directly, then connect to the User Plane Function (UPF) entity, which is responsible for data forwarding and network service quality assurance within the network. After that, it connects to edge computing devices to push remote processing functions to the edge, enabling local storage and processing of logistics tracking data and minimizing network latency.

[0036] This embodiment addresses the monitoring needs of numerous components, intermediate products, and logistics equipment during shipbuilding. Based on active tagging positioning / reading technology, which combines 5G networks, UWB positioning technology, and active tagging, it accurately identifies intermediate products, pallets, and logistics equipment, recording / uploading the status information of monitored objects. This achieves synchronization between the location and status recording of monitored objects. Simultaneously, the active tagging electronic tags acquire location information, enabling digital and standardized management of the entire logistics information. Real-time tracking and monitoring of the flow of intermediate products and production progress during the production process allows for the identification of bottlenecks in the distribution of various intermediate products, promoting refined management and control of logistics and improving the efficiency and intelligence level of ship section assembly process design.

[0037] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
