The ASFA Digital System is installed on a wide range of RENFE vehicles in Spain, featuring both hardware and software engineered in-house by Medha. Medha also offers comprehensive system integration services for various railway applications. The entire system is certified to SIL-4 safety level.
How It Works
- The ASFA Digital System receives driving information from the track and displays alerts and guidance to the train operator, assisting in safe train handling.
- If the system detects a deviation from the prescribed speed limits, it automatically engages the train’s emergency brake, acting as a protective safety measure.
- The system continuously monitors speed along the train’s route using data from track-installed beacons, ensuring adherence to safety protocols.
Key Assistance Features
- In-Cab Alerts: Provides visual and acoustic indications for track signals, repeating signal information directly in the driver’s cab.
- Speed Supervision: Monitors the train’s speed based on active control parameters in the onboard system, triggering emergency braking if necessary.
- Driver Performance Monitoring: Supervises the driver’s response to ASFA Digital signals, ensuring compliance with safety requirements.
Main Features
- Integration with Train Systems: Interfaces seamlessly with braking systems, battery, legal recorders, ERTMS/LZB, and frequency sensing subsystems.
- Comprehensive Signal and Event Logging: Captures detailed signal and event data for analysis using the Event Logging System Analysis Software.
- Customizable Parameters: Allows customization of system parameters to meet specific operational requirements.
- Highest Safety Standards: Certified to SIL-4 and compliant with CENELEC standards EN 50129, EN 50128, and EN 50126.
Medha’s ASFA Digital System offers a robust and reliable Automatic Train Protection solution, enhancing safety and operational efficiency across railway networks.
