Train Diagnostic System ® MITRAC -TDS Adtranz - A Member of the Daimler. Chrysler Group 09

Agenda l Functionality of the TDS - Products l Supported Vehicle Structures l MITRAC®-TDS Architecture u u u data model component model communication model Adtranz - A Member of the Daimler. Chrysler Group 09

Functionality of the TDS Products l Software products which support transmitting, storing and off-line evaluation of train and vehicle related diagnostic data. l diagnostic related data are: u disturbance data with environment data u event data u condition data Adtranz - A Member of the Daimler. Chrysler Group 09

Supported Hardware Topologies 1 l the following topologies are supported: u stand-alone vehicles u trainsets (preferable connected by a TCN bus) u open trains (preferable connected by a TCN bus) u standalone subsystems Adtranz - A Member of the Daimler. Chrysler Group 09

TDS Overview l Corrective Maintenance u Event Data u Environment Data u Fault Texts l Preventive Maintenance u Condition Data Adtranz - A Member of the Daimler. Chrysler Group 09

MITRAC-TDS Architecture l TDS Data Model (What kind of data types are handled by TDS? ) l TDS Component Model (What components does TDS consist of? ) l TDS Distribution Model (How can the TDS components be distributed on a train ? ) l TDS Communication Model (How do the TDS components communicate? ) Adtranz - A Member of the Daimler. Chrysler Group 09

TDS Data Model: Event Data Event Description Environment Data l Disturbances/Protocol Events u Timestamped at event source u prioritized u active/passive edge l identification via: u Process ID / Event ID unique identification inside of MITRAC-TDS u up to 4 Error Codes is handled like texts u location geographical information, handled like texts u subsystem logical "module" information, handled like texts Adtranz - A Member of the Daimler. Chrysler Group 09

TDS Data Model: Event Data Event Description Environment Data nb of env data: 1 … 120 words 1 … 255 samples Adtranz - A Member of the Daimler. Chrysler Group 09

TDS Data Model: Condition Data l Used to store persistent application data over a long time u Parameters – – u Read-only (wheel-diameter) Read-write (adaptive control loop tuning) Counters – predictive maintenance (door cycles) l Condition Data is modified by Tools and Process: -> consistency is ensured by MITRAC®-TDS Adtranz - A Member of the Daimler.

Process Client for IEC 1131 Condition Data - state update Get. Condition. State ODBSState Update. CD Adtranz - A Member of the Daimler. Chrysler Group 09

ODBS l Stores Events and Condition Data l supports 4 languages l features a cache mechanism l features the state update mechanism Adtranz - A Member of the Daimler. Chrysler Group 09

ODBS - Overflow behaviour different behaviour for two cases: 1. all memory is used 2. one event is toggling all the time Event database ring buffer Storage model for a single event -> oldest events are overwritten -> latest occurrence of the very same event is overwritten Adtranz - A Member of the Daimler.
