Certifications

Multitel offers tests for a number of ERTMS contitutents and sub-components, including Eurocabs (EVC), Eurobalise, BTM (Balise Transmission Module) antennas, DMI (Driver Machine Interface) units, JRU (Juridical Recording Unit) units.

EVC Lab

The Eurocab MultiRailLab laboratory of Multitel provides ISO 17025 (BELAC 427-TEST) accredited EVC tests, for Subset-076 and Subset-094 (any version). Accreditation BELAC number 427-TEST was granted on 22nd February 2011.

This accreditation was greatly due to the SA-TAV (Semi Automatic – Trip Analysis and Validation) tool developed by Multitel for the analysis of the Subset-076 results.

SA-TAV can also be used for the validation of track lines, either with the use of an EVC simulator or with commercial onboard units connected to the track simulator of Multitel. This is very useful to anticipate problems during the validation of track signaling implementation, operational rules deployment and conformity with the SRS, therefore reducing the cost of the expensive line tests.

Thanks to the automation of the EVC laboratory, including DMI automatic image recognition, the 24/7 operation with robots, full Subset-076 campaigns are possible within 1 month, including analysis up to the requirements level.

This laboratory can not only be used for Subset-076 tests, but also for testing real tracks, connect with RBC and Interlocking and performing operational tests. For that purpose, the laboratory allows the edition of the track elements, balises, radio messages and rules for the operation and test.
Dedicated interfaces, assure the real-time validation of the of the laboratory tests, including measurement of performance and reliability of the system, due to its fully automated operations

  • EVC Laboratory Tests

The Eurocab MultiRailLab laboratory of Multitel has obtained ISO 17025 accreditation for EVC tests, for Subset-076-5-2, Subset-076-6-3 and Subset-094 from BELAC. Accreditation BELAC number 427-TEST.

This accreditation is greatly due to the SA-TAV (Semi Automatic – Trip Analysis and Validation) tool developed by Multitel for the analysis of the Subset-076 results.

SA-TAV can also be used for the validation of track lines, either with the use of an EVC simulator or with commercial onboard units connected to the track simulator of Multitel. This is very useful to anticipate problems during the validation of track signalling implementation, operational rules deployment and conformity with the SRS, therefore reducing the cost of the expensive line tests.

Eurobalise BTM Lab

Multitel provides Subset-085 v2.2.2 ISO 17025 accredited tests (BELAC 427-TEST) of Eurobalises and BTM antennas.

Additionally to this tests Multitel performs aging tests and compatibility tests of ERTMS Eurobalise and BTM components with non ERTMS systems, indentifying problems with clear description of the causes and traceability to ERTMS standards whenever applicable.


  • Eurobalise, BTM Laboratory Tests

Multitel is prepared to perform Subset-085 v2.2.2 tests of Eurobalises and BTM antennas. Additionally the Eurobalise MultiRailLab of Multitel provides MultiRailLab Balises for ERTMS laboratories, as well its signal MixerBoxes for the simulation of air-gap high speed telegram transmissions.

Innovations

Automation of the ERTMS test bench laboratory based on subset 094 through the use of automatic image recognition and automated multiple process control (thus, reducing the supervision necessary for carrying out a full certification process).

Generic EVC hardware inteface Multitel develops hardware interfaces, compliant with subset 094 that can also directly connect to the onboard unit, thus avoiding the development of adaptation boxes that are used by the industry just once, during the certification process.

New tools to support ERTMS expert validation: Based on the expertise of Multitel in Image Processing acquired through more than 8 years of research in signal processing and Image processing, Multitel has developed the DMI Event Manager which enables to automatically recognize Driver Machine Interface Events recorded by a camera from the on-board DMI equipment as show in Figure 1 below.

The high-definition acquisition tools in Eurobalise/BTM lab allow to sample the uplink signal of your device at very large bandwidth (0-400M Hz) and very high precision (14-bit quantification). The rich information contained in these high-definition signals can help you to analyse and to improve the quality of your device.

Applications

  • Using our EVC Test bench laboratory to bring services for onboard & track-side equipments certification (ERTMS)

  • Using our DMI Event Manager to fasten the process of the validation of the test results from videos of DMI

  • Rail QoS monitoring (including GSM-R)

  • Using our Traffic Simulator to test and validate the communication and configuration of multiple on-board equipments with the track side infrastructure (RBC, Interlocking, …), to help improving the train regulation (automatic route setting) and to assess ERTMS line capacity
