“Dear passengers, welcome aboard the intercity train to Ghent and Antwerp Central Station. The next stop is Waregem.”
On-board communication means reliable audio broadcasts. In this respect, the architecture of the on- board audio communication system must be carefully considered. To ensure high functional reliability, a fallback method is no luxury.
Televic GSP’s Train Audio Communication System (TRACS) and the Importance of Its Innovative Digital Fallback
Our audio platform for railway applications – TRACS – is a complete audio solution consisting of modular and configurable base components or devices. The TRACS product line stands for high-quality audio and functional reliability. On top of that, its configurability, modularity and security ensure we can provide our customers with a state-of-the-art and flexible future- proof platform.
The TRACS functionalities enable many different on-board communication expressions. These vary from crew to passenger messages, playback of pre-recorded messages, to warning tones and music broadcasts via the public address system. The intercom functions ensure crystal-clear communication between crew members and between passengers and the train crew.
Some of the advantages of TRACS:
- Superior audio quality with state-of-the-art audio algorithms, low latency, high intelligibility even at severe ambient circumstances
- High reliability: functional reliability increased by architecture choice using same base components, both analogue and digital fallback support
- Low risk & upgradable: thanks to the modular approach and up-to-date software stack
- Secure maintenance interfaces
- Configurable: customisation via parameterisation of ‘proven design’ software: zoning, audio settings, priorities, functional behaviour of IO, etc.
- Designed to optimise the total cost of ownership (TCO): in order to be efficient during the full product lifecycle, it’s easy to integrate, commission, install and maintain, different architectures for different needs with plug and play operation and long term support
