Availability and Safety Integrity of Train GNSS Positioning
摘要
Abstract
GNSS-based train positioning can effectively reduce operation and maintenance cost,improve the safety of railway. Starting from the problems of applying the GNSS to high-speed train location,based on the analysis of the existing train positioning availability and safety integrity,this paper discusses the construction of GNSS-based multi-sensors integrated positioning model,and the GNSS positioning availability through adap-tive Federal Kalman filtering algorithm. According to railway safety standards,by using the failure modes analy-sis,it explores the internal conjunctive mechanism between GNSS safety standards and railway RAMS(reliabil-ity,availability,maintainability and safety),solving the GNSS positioning safety integrity issue,which would lay theoretical foundation for safety application of GNSS in China's high speed railway system.关键词
