Application Examples

Passenger Information

Systems

To make public transport more attractive

and better accepted, more and more

dynamic information systems are being used

to inform the passengers on the current

trafﬁc situation.

For passenger information systems in trains,

streetcars and buses a Spanish c ompany

uses MEN components for a central

computer unit and the entire I/O needed for

system communication.

Passenger information is mostly done

automatically, but the control room shall

also be able to adapt the information

content as needed.

This way, the passengers can get important

or interesting additional information. The

control computer links the incoming data

with the original schedule data, analyzes

deviations and displays them on the info

screens. The audio component that can be

integrated as an option allows announce-

ments over speakers.

Tilting System

A Spanish manufacturer of railway vehicles

equips his electro and diesel motor train

units with active tilting technology for rail

routes in Spain. Control is in the hands

of VMEbus systems from MEN that are

equipped with timers/counters, analog I/O,

TTL I/O and CAN interfaces and run under

a real-time operating system.

Tilting technology uses sensor-controlled

actuators which make the railcar body move

as programmed depending on the centrifu-

gal force.

The tilting angle may reach 8°. The train

counteracts the centrifugal forces and can

therefore travel through turns at up to 30%

higher speed, as long as there are no safety-

related speed limits.

The purpose is to make the trip more

pleasant for passengers and to considerably

shorten trip duration on winding routes.

Railway Signaling

Systems

Operation of switches requires 100%

reliable electronics and is one of the most

safety-critical applications in the railway

area. Alcatel Transport Automation Solutions

has developed an Electronic Interlocking

System called “LockTrac“ that uses standard

CompactPCI

®

components from MEN.

The redundant, self-monitoring interlocking

computer is qualiﬁed for -20 to +70°C ope-

ration temperature. It is based on standard

hardware components (19“ technology,

CompactPCI

®

, M-Modules™, PC-MIP

®

).

The computing equipment in this appli-

cation is installed in hundreds of railway

stations in Austria, Switzerland, Hungary,

Spain, Iran and Scandinavia.

Another manufacturer in Italy uses MEN

standard CompactPCI

®

Intel

®

based single-

board computers in 3U format to build up

double-redundant systems for signaling

control systems.
