With the speed-up of trains, the train's positioning environment becomes increasingly complex which requires the train's positioning system have enough anti-interference capability to ensure the precision and reliability of train's positioning. GNSS/INS deeply integrated positioning system could improve the anti-interference ability of the positioning system, achieving real-time positioning with much...
Data fusion algorithm is an important guarantee about the performance level and complete function of the train positioning system. Since conventional Kalman filter methods in GNSS/INS integration frame could not solve the problem of nonlinear model. In this paper the Gaussian particle filter (GPF) is introduced, which is an efficient variant on the particle filtering algorithm for nonlinear hybrid...
This paper studies Multi-Resolution Modeling (MRM) method of Train Control System based on multi resolution modeling (MRM) and analyses in detail about aggregation-disaggregation theory as well as consistency of MRM. Due to the characteristics of Train Control System as being multi-node and distributed, subsystems of Train Control System using different resolution modeling methods concerning hierarchy...
The research on low-cost train control system is one of the most important part in train traffic field, using GPS data could realized real-time, safe and reliable train positioning. The train control system special database was studied systematically, the data model and mathematical topology model of data format was established, and the whole seven steps of special database creation were designed...
