dcterms:description
The objective of the presentation is to show, what are fundamental differences between aeronautical and railway safety philosophies from viewpoint of Global Navigational Satellite System (GNSS) applications, how the Galileo SIS quality measures were derived, what is their practical meaning and how it is possible to employ them for practical design of a safe Train Position Locator (TPL).The safety assessment starts from classification of Galileo SIS integrity and continuity risks by failure modes. It is shown how integrity and continuity risks influence railway safety and what impact these risks have on dependability of a safety related system. The interpretation of the Galileo quality measures in terms of RAMS (Reliability, Availability, Maintainability and Safety) according to the standard EN 50126 is proposed. Finally, the practical application of the Galileo quality measures for safety assessment of a TPL is demonstrated. Předmětem prezentace je ukázat, jaké jsou základní rozdíly mezi bezpečnostní filozofií v letectví a na železnici z hlediska GNSS aplikací, jak byly odvozeny ukazatelé kvality Galileo SIS, jaký je jejich praktický význam a jak je možné je využít pro praktický návrh vlakového polohového lokátoru. Stanovení bezpečnosti začíná klasifikací rizika integrity a rizika kontinuity satelitního signálu Galileo pomocí poruchových módů. Je ukázáno jako rizko antegrity a kontinuity ovlivňuje železniční bezpečnost a jaký dopad tyto rizika mají na spolehlivost systémů se vztahem k bezpečnosti. Je navržen výklad ukazatelů kvality Galileo ve smyslu RAMS (bezporuchovost, pohotovost, udržovatelnost a bezpečnost) podle standard EN 50126. Na závěr je předvedena praktická aplikace ukazatelů kvality Galileo pro stanovení bezpečnosti vlakového polohového lokátoru.
