In the automotive final assembly workshop, the repair area serves as the last checkpoint for quality control, yet it often becomes an efficiency bottleneck due to management challenges.

The final assembly repair area of a leading domestic automaker's factory is spacious with no fixed storage locations. Vehicles are parked densely and identified only by VIN codes, making them difficult to locate. Issues such as incorrect pickup and missed repairs occur frequently.

To address this problem, the factory introduced Woxu's UWB high-precision real-time positioning solution, assigning each repair vehicle a "coordinate ID." This completely resolves the core management issues in the repair area, enabling a leap from manual vehicle searching to intelligent positioning.

Project Pain Points: Three Core Management Challenges in the Repair Area

1. Extremely Low Vehicle Location Efficiency & High Labor Costs

The repair area has no fixed storage locations. Vehicles are parked densely and identified only by VIN codes, forcing workers to check each vehicle one by one to find the target. The average time for a single vehicle search is 18 minutes, which consumes significant labor resources. Additionally, human errors often lead to incorrect pickup and missed repairs, affecting the overall production rhythm.

2. Failure of Traditional Positioning Technologies

Positioning technologies like Bluetooth and Wi-Fi have an error margin of over 10 meters, unable to accurately locate individual vehicles. They completely fail in the complex environment of the repair area and cannot meet the needs of refined management.

3. Loose Task Management & Difficult Data Traceability

Repair tasks are disconnected from vehicle locations, making it impossible to monitor task progress in real time and calculate repair efficiency. The lack of historical trajectory records makes it difficult to trace data such as vehicle movement paths and detention time, preventing management from conducting accurate analysis and optimization.

Solution: Woxu UWB Positioning – Full Coverage + System Integration to Solve Workshop Positioning Issues

To address the core needs of "difficult vehicle location and difficult traceability" in the automaker’s final assembly repair area, Woxu customized a UWB high-precision positioning solution. Through "accurate hardware deployment + software system integration," a full-process intelligent management system is built:

1. Full Coverage of Two Core Areas

The final assembly repair area (170m×140m) and the CP9 key inspection area (80m×24m) achieve full UWB signal coverage. 135 anchors ensure no signal blind spots, and over 700 positioning tags meet the simultaneous online positioning needs of all repair vehicles in the workshop. Each vehicle has real-time "coordinates and traceability," completely eliminating manual vehicle searching.

2. Seamless Data Integration Across All Systems

A refined workshop scenario model is built based on UWB positioning technology, connecting the data interfaces of three core systems: IOT, MES, and AVI. Positioning data is synchronized to the production business system in real time, supporting repair task assignment and progress monitoring, while automatically calculating repair efficiency and generating daily reports. This realizes the full-process intelligence of "positioning - management - analysis" without the need for manual secondary data entry.

Core Functions: Six Capabilities to Solve Repair Area Management Issues

1.Real-Time Vehicle Positioning: Locate Target Vehicles in Seconds

The system supports quick query of real-time vehicle positions via VIN codes, with centimeter-level positioning accuracy. Workers no longer need to check each vehicle one by one, reducing the vehicle location time from 18 minutes to seconds. Meanwhile, vehicle coordinates are displayed in real time on a large screen, with different colors distinguishing vehicle models and repair statuses (e.g., pending repair, under repair, completed), providing a clear overview of the workshop situation.

2. Closed-Loop Management of Repair Tasks: Real-Time Progress Control

The system is deeply integrated with the IOT quality entry system, automatically obtaining vehicle repair tasks and assigning them to relevant personnel. It supports real-time monitoring of task execution progress, records task duration, and calculates work efficiency by linking with repair personnel, avoiding task delays or omissions and forming a closed-loop management of "assignment - execution - statistics."

3. Historical Trajectory Tracking: Full-Process Traceability

The historical movement trajectory of any repair vehicle can be queried via VIN codes, with support for multi-speed playback of the trajectory process to clearly restore the vehicle’s flow path in the repair area. It also automatically records the time when vehicles enter and exit each area, providing data support for production process optimization and abnormal problem traceability.

4. Intelligent Geo Fence Management: More Accurate Zoning Management

The system allows custom setting of electronic fences for key workstations such as CP7, CP8, water test line, and inspection line. It supports the calculation of at least 500 fences and the positioning of 1500 tags to meet future expansion needs. Fences can be flexibly deleted and modified, and vehicle statuses are displayed in different colors. It also automatically identifies the production line to which vehicles belong, realizing refined zoning management.

5. Multi-Dimensional Alarm & Early Warning: Risk Prevention in Advance

Multiple alarm mechanisms are set up, covering scenarios such as vehicle area crossing, missing/damaged/low-battery tags, vehicle over-detention, and tag removal from the workshop. Once an alarm is triggered, the system immediately sends a notification to managers, ensuring risks are addressed in the early stages to avoid affecting production.

6. Data Statistics & Visualization: Supporting Management Decision-Making

Daily reports for the repair area are automatically generated, calculating core data such as daily output and repair efficiency, and synchronizing to the IOT system. Heatmaps are generated based on the density of positioning devices, intuitively showing the congestion situation in the repair area. This helps management optimize vehicle parking layout and personnel scheduling, improving overall operational efficiency.

Case Value: Comprehensive Upgrade from Efficiency to Management

After introducing Woxu’s UWB high-precision positioning system, the repair area achieves real-time control of elements for the first time. This is driven by the refined capabilities brought by UWB positioning: real-time coordinates, trajectory traceability, and electronic fences. These capabilities integrate previously scattered on-site data into a continuous data chain, providing a scientific basis for workshop layout optimization and process improvement, and helping the enterprise build an "intelligent, efficient, and low-consumption" final assembly repair management model.
