Analysis and development of the entire software required to implement the PIS (Passenger Information System) module installed on board of high-speed trains built by Ansaldo/Breda for the Dutch and Belgian railways. The system was developed in accordance with the technical specs AB AA03AH6. For the management of the connectivity among the PIS modules installed in each train coach, the requirements have been met by developing WISP, an ad-hoc protocol that provides LAN network services (e.g. Socket) in non-exclusive mode (without declared Mater) on Rs485 multidrop connection. Further on, an interface to bus MVB and UIC 568 has been developed for interaction with external devices.
The system provides automatic route management, by taking via MVB the GPS current position and all other parameters related to the train’s operations. It also provides continuous information to passengers on internal and external display boards and multilingual audio summaries. In addition to the information to passengers and Intercom messaging, the project included the implementation of all configurations, diagnostic and visualization of system parameters. To this purpose, a special video/keyboard console has been installed in each coach for use by the train staff. The project was developed for Tattile S.p.A. on behalf of the final client Ansaldo Breda.
