UWB Vehicle Management Solution for Automotive Manufacturing Plants

Pain Points and Requirements in Vehicle Production Plants

Pain Point 1: Lack of Electronic Information Collection Methods:

Tasks such as inspections, production progress surveys, and production completion surveys mostly occur on the production floor. Data is manually recorded and later entered into computers, leading to delays and high error rates. Data collection, storage, continuity, and traceability are insufficient.

Requirement 1: Faced with heavy information collection workloads, traditional manual methods can no longer meet the increasingly accurate information collection needs of enterprises. Electronic data collection and storage methods are required to ensure the continuity and traceability of quality data. Incorporating UWB positioning for information collection enables real-time monitoring of production vehicle locations in specified areas, counting quantities, recording entry/exit times for workstations, and generating electronic reports. This ensures data real-time accuracy and reduces statistical errors.

Pain Point 2: High Error Rate in Vehicle Information Collection During Temporary Production Plan Adjustments:

Offline vehicle inspection involves numerous workshops, including pressure testing, damping, wheel alignment, assembly delivery inspection, and static/dynamic assembly inspection workshops. These various workshops inspect vehicle body manufacturing quality from different processes. The main challenge is how to address data recording omissions or errors caused by internal temporary production plan adjustments, ensuring accurate recording of vehicle manufacturing information for quality supervision departments.

Requirement 2: Installing positioning tags on the vehicle windshield and associating them with vehicle barcodes allows for quick recording and locating of vehicle positions. Changing supervision areas by modifying electronic fences via the platform enables an intelligent, immediate-use recording method.

Pain Point 3: Lack of Tools for Collecting Production Capacity Information, Making Efficiency Analysis Difficult:

Addressing production capacity imbalances in the vehicle body manufacturing process requires processing, analyzing, and tracing large amounts of vehicle production information, which is time-consuming.

Requirement 3: Supervising production efficiency requires calculating the time consumption for each process from the production source, incurring significant labor, material, and time costs. The vehicle production report function of a UWB positioning system can accurately record dwell times at each workstation and the number of vehicles in production within workshops. Optimizing production capacity reduces vehicle time on the production line, improving manufacturing and delivery efficiency.

Pain Point 4: Potential Undetectable Hazards from Incorrect Tool Usage

During automotive production, incorrect tool usage can lead to improper installation of vehicle components, posing safety risks.

Requirement 4: Attach positioning tags to tools. Each tool must be used at its designated workstation. If a tagged tool leaves its specified work area, the vehicle production management system sends a command to disable the tool's function.

The UWB positioning products developed by West-HN Technology are well-suited for the management needs of the automotive manufacturing industry and have been validated in several enterprises.
