zentrak Profile Validation System

The zentrak Profile Validation System (PVS) is used to monitor the train profile.

Train Profile Surveillance

Slipped loads due to improper fastening or travelling vibrations of train vehicles are major issues in railway transport. Objects sticking out of a train's reference profile can cause serious injury to persons and can lead to extensive damage to railway infrastructure.
The PVS is designed to detect reference profile violations on passing train vehicles. This precise and reliable surveillance system protects persons and railway infrastructure and avoids accidents with passing trains. Event based image recording allows the operator to verify the alarm and identify the severity of the profile violation.
