In the railway sector, where safety is a key value, the effectiveness of fire protection systems plays a crucial role. The SIL2 Fire Extinguishing System, developed by Eletech, Head of the International Design Centers of Elemaster, R&D division of the Group, is an excellent example of how advanced technology can be used for a fast and reliable response to train fires. This system not only improves operational safety but also marks a significant step forward in the management of rail emergencies. Going forward, we will explore in detail the features, operation and benefits of this cutting-edge solution, highlighting its impact on safety and efficiency in the rail sector.
Description of the SIL2 Fire Extinguishing System
The SIL2 Fire Extinguishing System is a sophisticated solution that integrates centralized control units and intelligent sensors for early detection and fire management. Based on Smart infrared sensors, the system can handle up to 127 sensors, ensuring extensive and detailed coverage of the train.
Main Features
- SIL2 Safety Level: The system strictly complies with SIL2 level, ensuring a high standard of safety.
- Standard Compliance: Developed according to EN 50155, the hardware design follows EN 50129 and the software one the EN 50657, ensuring that every component of the system meets the highest standards.
- Advanced Architecture: Featuring a dual-channel architecture with two redundant CAN buses, the system ensures reliable communication in accordance with EN 50159.
- Integrated Communication: It uses Ethernet with TRDP protocol to interface with the train control unit TCMS, facilitating a centralized and coordinated management of alarms and shutdown operations.
- Integrated Web Server: The system includes a web server for maintenance and configuration, making system management operations more accessible and easier
- Zone Valve Control: Allows specific control of areas, localizing the shutdown intervention where necessary.
- Effective Alarms: It has dedicated outputs to activate visual and audible alarms, alerting passengers and staff effectively.
Operation and Impact
The system, with its ability to quickly detect fires through advanced infrared sensors, automatically activates fire-fighting countermeasures in the detected areas, minimising damage and protecting passengers and train staff. The redundant architecture and secure communication ensure that, even in the event of a partial failure, the system continues to operate effectively.
Test and Verification
To ensure reliability and compliance with safety standards, the SIL2 Fire Extinguishing System underwent rigorous testing, including real-world scenario simulations and code coverage analysis, to verify that all parts of the software were fully tested and error-free.
