Advanced Automotive Side Mirror Endurance Testing System
In this project, we demonstrate a complete end-to-end industrial test solution for automotive side mirrors, powered by the R&D Robotics RDF Ecosystem. This rig is designed for high-cycle endurance testing, analyzing the electrical and mechanical health of the mirror folding and heating systems.
System Architecture
The heart of the system is housed in a compact 30x40cm industrial cabinet, providing real-time data acquisition and high-fidelity control through our specialized ecosystem:
- RD-PCW11: High-performance Windows 11 Industrial PC used for the main operator interface and centralized data processing.
- RDF-GW2: Industrial Edge PC and gateway, managing low-latency communications between the I/O modules and the PC.
- RDF-BDC: Specialized Brushed DC Motor Driver (5A Max) providing smooth control for folding/unfolding and 4-axis glass motion (UP/DOWN/RIGHT/LEFT).
- RDF-HEATER: Dedicated 5A driver for precision testing of mirror glass heating elements.
- RDF-4AI: 16-bit high-speed analog input module used for high-resolution current profile analysis.
- RDF-88DM: Handling digital logic, safety interlocks, and sequence triggers.
- RDF-4PT100: Precision environmental temperature monitoring.
- RDF-AO: Analog output for dynamic motor speed adjustment during motion cycles.
Key Features
Intelligent Diagnostics
Using Savitzky-Golay smoothing algorithms, the system distinguishes between normal commutation noise and actual mechanical defects.
Configurable Limits
Operators can easily adjust pass/fail thresholds (Ip, It_max, Duration) via a simple config file to suit different mirror models.
The result is a robust, highly accurate test stand that doesn't just pass/fail a product, but provides engineers with the "Truth" behind the mechanical movement through precise electrical signatures.
