Wayside Monitoring System (WMS)
OVERVIEW
The Wayside Monitoring System integrates specialized monitoring equipment into
a single database. This provides a means to correlate the individual
measurements and quantify interaction and relationships between such things as
wheel impacts, bogie tracking geometry and wheel wear.
The Wheel Condition Monitor is one component of the Wayside Monitoring System
(WMS).
Most wayside monitoring systems currently integrate disparate sensors with
customized software. By providing integrated information through “data fusion”
the WMS makes this information available to the customer’s existing IT
infrastructure. This decreases commissioning costs and shortens the time to
deliver data for engineering and operational departments.
The WMS is an expandable modular system that interfaces to selected vendor’s
sensors. Each of these optional modules can be added to the system at any time
and remain fully independent of the overall WMS. In this way, the WMS serves as
a high-level data infrastructure that does not interfere with or restrict the
standalone operation of each of the sensor systems in any way.
The current systems interface with the WMS under agreements with the respective
equipment vendors.

The following basic functionality can be integrated into the WMS:
-
Wheel Profile (100 kph / 60 mph)
-
Angle of Attack and Tracking Position (100 kph / 60 mph)
-
Vehicle Hunting (WID) Frequency and Severity
-
Axle Mass > non-certified (240 kph / 150 mph)
-
Lateral Force (240 kph / 150 mph)
-
Vertical Force (240 kph / 150 mph)
-
Wheel Condition (240 kph / 150 mph)
The integration of this information provides data ranging from individual
measures at the wheel level through to summary measures like gross tonnage,
total lateral and impact forces, consist loading evaluation and power to weight
ratios.
The core of the WMS is essentially a database software application containing
data from all sensors integrated at the train, vehicle and axle level.
