Advancing Digital Twin-Based Collision Avoidance: A Comprehensive Analysis of Communication Networks for...

Area of Science:

• Industrial Automation
• Wireless Communication Systems
• Functional Safety Engineering

Background:

• Wireless safety functions are critical in industrial environments but lack standardized performance criteria.
• Existing performance assessment models often oversimplify the dynamic nature of industrial settings.

Purpose of the Study:

• To develop a theoretical framework for evaluating the performance level of wireless safety functions.
• To address the challenges posed by dynamic industrial environments on wireless system reliability.

Main Methods:

• Developed a theoretical framework based on packet loss rates for performance assessment.
• Conducted an in situ measurement study on a forklift truck safety system for validation.

Main Results:

• Validated the proposed performance assessment method using real-world data.
• Highlighted the significant impact of warehouse dynamics on packet loss rates and safety function performance.

Conclusions:

• A simplified model based solely on packet loss is insufficient for complex industrial wireless safety.
• An expanded theoretical framework is necessary, incorporating warehouse dynamics and specific wireless system characteristics.
• There is a critical need for specialized standards and frameworks for wireless safety applications in industry.
