Wireless Vibration Monitoring
Synchronized sensing for predictive maintenance
We designed a wireless sensing system for vibration analysis in industrial environments, enabling predictive maintenance through synchronized, high-resolution data acquisition.
Project Overview
This wireless sensing system enables vibration analysis in industrial environments for predictive maintenance through synchronized, high-resolution data acquisition. The system forms a scalable foundation for real-time monitoring, early fault detection, and multi-channel diagnostics in demanding industrial settings.
A custom protocol ensures precise time synchronization across all nodes, compensating for inter-device clock drift to enable coherent multi-sensor analysis. This allows for advanced diagnostic techniques that require phase-coherent measurements across multiple sensing points.
To support field operation, all devices are stored in a charging tray worn on the user's belt, providing mobile power and centralized recharging between sessions. This innovative approach ensures continuous operation in industrial environments where fixed infrastructure may not be available.
