Safety-oriented acceleration and vibration measuring system
The content on this page was translated automatically.
Problem definition
- Rail transportation is exposed to high loads.
- Sliding or spinning of a driven wheel on a rail leads to heavy wear.
- This results in an enormous increase in maintenance and repair costs.
- Slip and skid detection are difficult to achieve due to the high loads.
Solution approach
- Development of a safety-oriented acceleration and vibration measurement system for safe skidding and sliding protection to trigger drive and control commands.
- Safe and fast detection of skidding and sliding processes based on real-time data.
- Intervention in drive and control commands.
System architecture:
- Control unit developed for SIL 3 in accordance with IEC 61508.
- 1oo2D safety processor.
- 1oo3 Vibration sensor system.
- Position detection via GPS.
- Transmission of safe sensor data via Ethernet to control and braking system.
- Transmission of sensor data to GUI.
- Local storage of sensor data on SD card.
