zentrak Automatic Vehicle Identification

The function Automatic Vehicle Identification (AVI) enables the allocation of measurement data to the correct train set, vehicle and/or wheelset by using Radio Frequency Identification (RFID) technology.

Allocation of Measurement Data

AVI reliably detects UHF transponders holding key information used in various railway applications. This for example allows railway operating companies to efficiently manage and locate their rolling stock assets and optimize maintenance processes.

The AVI function integrates seamlessly with other zentrak functions and is tailored to railway specific applications and standards. Transponder data can be automatically filtered based on the information received so that only the desired information will be processed, assigned to other monitoring data or forwarded to the user.
