MAIN GOAL
Trainset Network and On-board Modules
1- Warning Panel in locomotive used to gather
information from all on-board modules.
2- Allowing access to the Echelon network via cellular
communications for remote control and monitoring.

CELLULAR TECHNOLOGY
Warning Panel in Locomotive
• On-board industrial
PC-104 on Win CE.
• CNTC pass-thru interface
to allow Echelon network
communications.
• Modem transmits data via
TCP/IP on a cellular link.

Train Network Communications - 6
INTER-CAR NETWORK
Communication Process
• Connection to the Warning Panel (Win CE
industrial PC) from any computer with a modem
(MNP-10 cellular mode enabled).
• Communication protocol: TCP/IP.
• The Warning Panel acts as a pass-thru for the
Echelon network, allowing full Echelon
capabilities.
• Able to reach every single module in the trainset.

Train Network Communications - 8
CALL TO PAGER
Communication Process
• The BMS module sends an alarm (e.g. bearing probe
open).
• The alarm is sent to the Warning Panel through the onboard/inter-car Echelon network.
• The Warning Panel calls the paging service through its
cellular modem.
• The paging service then sends an alphanumeric alarm to
the pager: car number, module name and alarm description.

CUSTOM SOFTWARE
Main Features
• We wrote our own software.
• Compatible with Win95, Win98, Win2000
and Windows NT.
• We use the same software for On-board
Connection and Remote Access (via the
Warning Panel).

USING OUR SOFTWARE
Interrogate an
on-board module:
• Choose the car.
• Choose the module in
the car.
• View:
- logs;
- module status;
- module parameters.

WARNING GRAPH (1/2)
Bearing Monitoring System (BMS)
• From the Event History
menu, a graph is available on
Warning temperatures (last
100 minutes before the alarm
and next 100 minutes).
• Data saved in BMS: graphs
of the last 8 Warnings.
The graph shows what happened during the alarm: real problem?, false alarm?

WARNING GRAPH (2/2)
Bearing Monitoring System (BMS)
EXAMPLE of FALSE ALARM
Water infiltrated the probe. The
probe became short at -40 ºC at
14:15, 14:30, 15:00 and 15:20,
reaching the Danger level at 15:10
and 15:30.
These probes are thermistors. Their
resistance drops with the
temperature, making the distinction
difficult between a short-circuit and
a high temperature level.
