High-Speed and High-Precision Train Position Detection

초록

Along with dramatic change of social aspects, high-speed train operation frequency has been increased to provide safe, faster and convenient transportation. Here, KRRI (Korea Railroad Research Institute) is determined to develop better transportation by focusing on number of national R&D projects including “Technology development on the positioning detection of 400 km/h class railroad with high precision”. In this project, we are aiming to improve reliability and precision of the positional information using developing technologies instead of existing track circuit. In this paper, we propose developing overall structure of positional detection system integrated with various sensors such as Global navigation satellite system, inertial sensor and RFID.
