Wayside Train Measurement with ARGOS® from HBK

Precise and reliable measurement data for the rail industry

 

Precision pays for itself

The more accurate the measurement data in WTMS, the safer and more precise the implementation of changes to your existing rail system. Only valid and precise measurement data allows for the development of further business models and reliable strategies for preventive maintenance and cost reduction measures.

 

A safe future

The modular design of ARGOS® is its strength. ARGOS® is continuously developed to adapt to changing application requirements. ARGOS® can be tailored according to your needs, and extended at any time, making it future proof.

Compatibility and upgradeability
 

ARGOS® Systems provides you with the benefits of compatibility and upgradeability

 

Upgradeability

The modular systems can be uncompromisingly adapted to suit the application. The only components used are those necessary for the task at hand. A subsequent expansion of the configuration is not a problem. For example, an ARGOS® WIM system can be upgraded with an ARGOS® OOR module at any time.

 

Interfaces are our language

Integration with main control centres and third-party systems via standardized or customer-specific interfaces is simple. Modern vehicle management concepts are supported via a complete RFID integration.

The modules in detail

Measurement systems (high precision) – Wayside Train Measurement & Monitoring (WTM +M)

WIM

ARGOS® WIM (Weigh in Motion, dynamic weigher) can be used to acquire the load status of vehicles at normal line speed with the greatest possible accuracy. Vehicle weight, axle loads, wheel forces and loading state can be monitored efficiently and precisely.

 

  • Train weight: 1% to 100 km/h, 2% to 200 km/h
  • Vehicle weight: better 0.5% to 30km/h, 1.5% to 100 km/h, 2% to 200 km/h
  • Can be combined with OOR, WILD, LONG, PROFIL

Weight in Motion

RBM Straight

ARGOS® RBM Straight (Running Behaviour Measurement for straight lines, unstable vehicle run) continuously measures the horizontal and vertical forces to monitor the risk of derailment and detects hunting (instability, sine run). On straight tracks, some vehicles tend towards undulating running which can lead to instability.

 

  • Train weight: 1% to 100 km/h 2% to 200 km/h
  • Vehicle weight: 1.5% to 100 km/h 2% to 200 km/h
  • Horizontal forces: 3% to 100 km/h 5% to 200 km/h
  • Striking angle:  ±20 mrad
  • Can be combined with OOR, WILD, LONG, PROFIL

Hunting

RBM Curve

ARGOS® RBM Curve (Running Behaviour Measurement for curves, horizontal forces) continuously measures the horizontal and vertical on curves (lateral wheel force, track displacement force).

 

The task on curves, in addition to derailment safety, is to avoid unnecessarily high driving forces to reduce wear and stress on the superstructure.

 

  • Train weight: 1% to 100 km/h 2% to 200 km/h
  • Vehicle weight: 1.5% to 100 km/h 2% to 200 km/h
  • Horizontal forces: 3% to 100 km/h 5% to 200 km/h
  • Striking angle: ±20 mrad
  • Can be combined with WILD, LONG

OOR Stand-alone

ARGOS® OOR Stand-alone (wheel Out-of-Roundness) delivers reliable wheel shape irregularities with peak accuracy. It is available in a stand-alone version or as an extension module for other ARGOS® products. Its exact qualification and classification of wheel shape irregularities are the basis for modern predictive and descriptive wheel maintenance and unfailing infrastructure asset protection concepts.

 

  • 50 km/h to 250 km/h
  • Resolution better than 0.01 mm, measurement repeatability 0.05 mm as trend function, 0.1 mm as individual measurement
  • Flat point: 30 mm or greater
  • Polygonization order: 2nd to 32nd
  • Can be combined with PROFIL

OOR STAND-ALONE

Wheel Out of Roundness

ARGOS® DYN (Dynamic force and WILD – Wheel Impact Load Detection) can measure continuous dynamic forces exerted by the vehicle on the superstructure. The outstanding feature is its real continuous force measurement over the whole measurement rail section including the sleeper areas. This allows, as a side effect, the determination of the formation reaction coefficient.

 

  • Continuous dynamic force: 0.5%
  • Can be combined with WIM, RBM Straight

Dynamic Force

OOR

ARGOS® OOR (wheel Out-of-Roundness) measures the deviation from an ideally round wheel with an unreached accuracy. The measurement covers the entire circumference of the wheel in the area where the wheel has contact with the track. The measurement system is designed so that at least two overruns are measured for each wheel. The progression of delta R over the circumference of the wheel is used by the system to derive and quantify types of wheel shape irregularities.

 

  • 50 km/h to 250 km/h
  • Resolution better than 0.01 mm, measurement repeatability 0.05 mm as trend function, 0.1 mm as individual measurement
  • Flat point: 30 mm or greater
  • Polygonization order: 2nd to 32nd
  • Can be combined with WIM, RBM Straight

LONG

ARGOS® LONG (Longitudinal force) = measures wheel- and axle-specific braking and tractive forces in the longitudinal direction. This helps to identify unusual vehicle behaviour and has the task of avoiding unnecessarily high forces to reduce wear and tear on the rail infrastructure.

 

  • Longitudinal force: 3% to 250 km/h
  • Can be combined with WIM, RBM Straight, RBM Curve

PROFIL

The cross-wheel profile measurement system is a real-time solution that uses a combination of line laser and a high-resolution, high-speed camera for automatic cross-wheel profile measurement at line speeds. The data is used for trend analyses and predictive damage identification and maintenance. The measuring equipment is certified according to ISO 17025.
