UWB Warehouse Logistics Production Personnel and Goods Management Solution

I. Industry Status and Demand

Logistics refers to the dynamic state of commodities and other material resources across spatial and temporal changes. Consequently, logistics management largely involves managing the spatial and attribute information of goods and materials. In the intelligent logistics technology process based on the Internet of Things (IoT), smart terminals utilize sensing technologies such as Radio Frequency Identification (RFID), infrared sensing, laser scanning, and UWB precise positioning to acquire various attribute information of goods. This information is then transmitted via communication means to an intelligent data center for centralized statistics, analysis, management, sharing, and utilization, thereby providing decision support for logistics management and even overall business operations. The smart logistics industry currently faces the following pain points and demands:

Pain Point 1: In recent years, with the rapid development of e-commerce and manufacturing industries, the volume of goods in enterprise warehouses has multiplied. To improve storage utilization, companies have made warehouse aisle layouts increasingly dense. Simultaneously, the demand for picking personnel within warehouses has grown, making personnel management highly challenging.

Pain Point 2: Chaotic logistics warehouse management with insufficiently standardized management systems. Warehouse structures are often simplistic and layouts suboptimal. In some cases, picking and storage areas are mixed, with goods haphazardly piled in picking zones, frequently leading to lost or misplaced items.

Pain Point 3: Materials, products, etc., within enterprise warehouses lack clear identification or are unmarked altogether. There is no reasonable zoning, let alone defined picking paths or batch schedules. Management of materials, equipment, job responsibilities, and systems is not strictly formulated, resulting in difficulties in issuing materials, inaccurate quantities, and challenges in inventory counting.

Hainan Shidian addresses the difficulties and pain points of smart logistics applications by introducing a solution based on UWB wireless positioning technology. Tags are bound to warehouse personnel, enabling attendance tracking, absence alerts, and personnel dispatch management through their location information. Simultaneously, each storage location is meticulously zoned. Tags are bound to PDAs to indirectly locate goods, providing robust data support for warehouse inbound/outbound operations, goods picking, inventory counting, etc.

II. Overall Solution Architecture

The system comprises UWB tags, UWB indoor base stations, positioning engine software (C/S architecture), and positioning application systems. Positioning tags and base stations communicate via UWB pulse signals. The base stations transmit received tag data via 5G networks or wired Ethernet to the LS1000 positioning engine for data analysis and processing. The processed precise location data is then transmitted to upper-layer applications through open API interfaces.

The system consists of the following:

UWB Tags: Available in card-style and wristband-style, attached to personnel or objects to be located. They periodically transmit UWB signals containing tag ID information.
UWB Indoor Base Stations: Communicate with positioning tags and relay information back to the positioning engine algorithm software.
Positioning Engine Algorithm Software: Deployed on-premises. It collects underlying data and processes it through the positioning engine's algorithms to obtain the precise coordinates of the tags.
Positioning Application Software: Deployed on-premises or in the cloud. The application-layer software implements basic functions like location display and trajectory playback, as well as business functions extended from location data such as electronic fencing, intelligent inspection, attendance statistics, and video linkage.

III. Solution Features

Feature

Description

Personnel Tag Management

Bind and distribute tags according to a real-name system, one tag per person. Before issuing, tags must be bound to designated personnel on the platform, and personnel information must be entered.

Asset Tag Management

Tags are bound to PDAs, one tag per PDA. Before issuing, tags must be bound to designated PDAs on the platform, and PDA encoding information must be entered.

Personnel Statistics

Real-time precise positioning within warehouse areas, controlling personnel positioning accuracy within 1 meter. Personnel walking trajectories within shelves are confined to shelf aisles.

Entrance/Exit Management

Manage warehouse personnel entry and exit, requiring personnel to use designated entrances/exits to facilitate inspection of carried items.

Historical Trajectory Query

Personnel trajectory playback allows viewing of picking paths for specific time periods.

Attendance Records

Track attendance for warehouse personnel,统计上下班时间、调动任务以及统计分拣货物走动时间。

Absence Records

Record statistics for personnel leaving designated work areas.

Real-time Goods Location Management

Locate goods in real-time through direct or indirect methods (e.g., locating PDAs, pallets, shelves) with positioning accuracy around 30cm.

Storage Location Zoning (Area Division)

Optimize the layout of storage location zoning based on inbound/outbound goods trajectories to improve goods handling efficiency.

PDA-Tag Binding

During inbound operations, retrieve the associated positioning tag ID based on the PDA ID in the parameters. Obtain the most recent positioning coordinates near the scan time in the parameters, calculate which storage location they fall into, update the goods' storage location based on the waybill number/serial number in the parameters, and send the location to the backend.
