Abstract: Aiming at providing convenient, comfortable and safe full-trip intelligent information services for the passengers in Beijing-Zhangjiagou high-speed railway during the Beijing Olympic Winter Games, the concept of full-trip intelligent travel services is put forward with face recognition, travel service recommendation, service information push and station navigation as the main contents. Focusing on the three typical application scenarios of face recognition and ticket checking at entry and exit gate, all-around station navigation service, and intelligent information push service based on passenger trip, face recognition based on MTCNN model, collection and integration of trip service information, trip service information push, in-station navigation base map drawing, in-staion Bluetooth iBeacon positioning device deployment, fingerprint positioning, in-station navigation based on A* algorithm and other related technologies are studied in depth. The research and application of these technologies can better meet the personalized travel service needs of passengers, help to improve their travel experiences, and further promote the development of the Beijing-Zhangjiagou high-speed railway to the direction of intelligent railway.
