RTR 4/2010 46 InnoTrans – Even more railway than ever before! For the first time, Knorr-Bremse’s subsidiary, IFE, displayed its “E3” pressure-sealed door system for high-speed trains. The wide door opening makes it easier for passengers to board and alight. Additional safety is provided by a sensor system for detecting objects trapped in the door. A further novelty is the intelligent retracting step. This is equipped with an ultrasonic detector which measures how far the platform is away from the train and thereby determines how far the step can be driven out before even starting to move it. The Schaeffler Group is making a name for itself with intelligent wheel-set bearings. Its “Train Support System” is based on an integrated generator-sensor bearing (GSB). This generates electrical energy from the rotation of the wheel set using a permanent magnet positioned in the axle. A separate, autonomous source of energy is thus available. The energy is stored and can be used for functions such as the automatic opening of doors or for detecting switches and sensors. For the purpose of its Train Support System, the Schaeffler Group has now added intelligent electronics to its GSB and linked it in with a higher-level informationmanagement system. The on-board unit is capable of registering the state of the bearing, the wheel set and the rail and of passing this data on to a higher-order command and control system via a satellite vices from Knorr-Bremse. In trams, the compact HGK hydro device with a brushless DC motor brings about a reduction in lifecycle costs. The elastically mounted HSE1A active brake calliper compensates for the relative movements between the brake disc and the calliper mounting. Knorr-Bremse also presented its EP2002 Cube brakecontrol system for metro trains and multiple units. This mechatronic system now also integrates the additional pneumatic functions of the parking brake and the air suspension. Fig. 12: New switches from Schaltbau link. A Nuremberg-based registered association known as CNA (Cluster Neuer Adler e. V.) awards a prize for innovation in “intelligence for transport and logistics”, which this year went to the product development just described. 4 Electronics Numerous innovations were presented at InnoTrans by ABB Railway of Berlin, including the Bordline CC1500 compact power converter, asynchronous traction motors, switchgear modules for railway power-supply systems, a compact traction transformer for the new Velaro D high-speed train from Siemens and a cadmium-free fast-acting DC circuit-breaker for metros and trams. Schaltbau GmbH adopted the motto of “On track with global expertise” for presenting the new generation of power controllers and toggle switches for driver’s consoles (Fig. 12). Thanks to their coloured illumination and up to eight two-way contacts, they can be used flexibly for all sorts of demanding functions. The telematics division of the Swiss Ruf group presented new components for the delivery of acoustic information to passengers. Its distributed audio hub, known for short as “VisiWeb DEA”, is an audio router which transmits and receives digital audio signals and supports connections with numerous input and output devices. Typical applications are the linking in of microphones, handsets and loudspeakers with the system as a whole. The audio hub can be individually addressed, so that selective announcements are possible. There is no problem in connecting VisiWeb DEA to UIC cables. Moxa of Taiwan displayed industrial-grade Ethernet switches, wireless products and IP cameras for industrial communication and surveillance tasks and also for use in railway vehicles – all of them in conformity with EN 50155. Its ToughNet series offers an extensive selection of products for building up an Ethernet backbone in networks on trains.
