Functionality of the TDS - Products

Software products which support transmitting, storing and off-line evaluation of train and vehicle related diagnostic data.

diagnostic related data are:

disturbance data with environment data

event data

condition data


Supported Hardware Topologies 1

the following topologies are supported:

stand-alone vehicles

trainsets (preferable connected by a TCN bus)

open trains (preferable connected by a TCN bus)

standalone subsystems

MITRAC-TDS Architecture

TDS Data Model (What kind of data types are handled by TDS?)

TDS Component Model (What components does TDS consist of?)

TDS Distribution Model (How can the TDS components be distributed on a train ?)

TDS Communication Model (How do the TDS components communicate?)


TDS Data Model: Event Data

Disturbances/Protocol Events Timestamped at event source prioritized active/passive edge

identification via: Process ID / Event ID unique identification inside of

MITRAC-TDS up to 4 Error Codes is handled like texts location geographical information,

handled like texts subsystem logical "module" information,

TDS Data Model: Condition Data

Used to store persistent application data over a long time

Parameters– Read-only (wheel-diameter)– Read-write (adaptive control loop tuning)

Counters– predictive maintenance (door cycles)

Condition Data is modified by Tools and Process:-> consistency is ensured by MITRAC®-TDS

Storage model for a single event

-> latest occurrence of the very same event is

overwritten
