UNIAC[2] Axle Counter

UNIAC[2] is an axle counting system, which is flexibly adaptable and configurable meeting highest possible levels of safety and reliability.

The UniAC[2] axle counting system is based on a modular structure and therefore ensures flexible scalability. UniAC[2] can be based on a central structure (i.e. in a central signaling room for the whole railway station) or decentralized next to the tracks in order to shorten the cable length between the wheel sensor (the external equipment) and the axle counting system (the internal equipment).

Technical features:

  • Approval according to CENELEC SIL4 by TÜV-Süd in Braunschweig
  • 0 km/h - 400 km/h
  • -40°C – +80° C (internal equipment)
  • 19 V DC – 72 V DC power supply

Benefits:

  • Easy and suitable configuration tool based on graphic user interface (Application Architect)
  • Modular hardware structure
  • Combined evaluation and counting module
  • Relay, optical coupler or protocol interface
  • 20 mA current loop signal that has the highest resistance to various EMC influences and environmental conditions
  • Master Reset
  • Configurable basic parameter sets for easily and fast configuration of the system
  • Modern diagnosis, including online storage of analogue signals

Performance features:

Beside the known features of an axle counting system the development of the system has also taken further functionalities into consideration. The UniAC[2] systems comes with the possibility of superimposing physical counting sections, with virtual counting sections. The virtual counting sections supervise the physical counting sections and in case of failure are able to automatically reset it. This procedure enables the operator to increase the availability of the axle counting system. Beside the new generation of the axle counting system is able to measure speed of each counting point. Big attention has been paid on the development of a comprehensive and userfriendly diagnosis. Especially it needs to be pointed out that the analogue signals can be recorded without any additional loggers. This information can then be displayed on a dedicated web page for the customer or can be saved locally for future analysis.
