J. Mendizabal, I. Adin, G. Solas, L. Valdivia, G. de Miguel. “Evolution of testing: field testing, laboratory testing and virtual testing: BTM case study”. 12TH UIC ERTMS WORLD CONFERENCE, 29th February till 2nd March 2016, Brussels.

* Abstract

The poster is focused on testing and validation. It shows how the evolution of testing will move from field test to laboratory testing in order to reduce the expensive and long filed testing campaigns. Moreover, the benefits of moving from laboratory testing to virtual testing will be also shown. Current trend in testing goes from field testing to laboratory testing and finally to virtual testing.

A case study of the ETCS’ track eurobalises and on-board eurobalise equipment (BTM) will be shown:

·         Balises field testing: by means of testing equipment installed on-board balise signls, noise and interferences found in the air—gap are captured. This allows to the validation of the balises and identify the immunity level required for BTM. How measurements are done and the prupose will be shown.

·         Balise and BTM laboratory testing: according to SUBSET-036 and SUBSET-085 the laboratory testing strategy and equipment are analysed. They allow the validation of track eurobalises and on-board eurobalise equipment (BTM) in the laboratory. Moreover, SUBSET-116 related to laboratory validation of the on-board eurobalise equipment (BTM) will be analysed. Additionally, a new methodology for susceptibility laboratory testing will be shown and the link to the field testing results explained.

·         Balise and BTM virtual testing: a specific tool BET (Balise Evaluation Tool) for the virtual testing of the track eurobalises and on-board eurobalise equipment (BTM) allows to carry out the simulation of any scenario modifying the performance of the balises (type, power, debris), the air-gap (noise, and interferences obtained from field testing, SUBSET, etc.) and the performance constituent of the BTM (antenna, demodulation, etc.). Moreover, BET has been integrated in a virtual laboratory based on SUBSET-094 and a virtual kernel based on (SUBSET--26). SUBSET-076 and real scenarios obtained from field measurements have been simulated in order to test the behavior of the system.

Virtual testing together with laboratory testing allows the HIL (Hardware in the loop) testing, where subsystems are tested in their environment without the need of having the real equipment to complete the environment.
