Train running seamless monitoring system based on satellite differential positioning and UWB positioning

The invention relates to a train running seamless monitoring system based on satellite differential positioning and UWB positioning. The train running seamless monitoring system based on satellite differential positioning and UWB positioning is provided in order to adopt the satellite differential positioning in wide areas to improve the positioning accuracy of the position of a train, meanwhile, the train can be monitored in the whole journey, and safety and reliability of dispatching and running of rail traffic are improved. According to the technical scheme, the system is characterized in that the system comprises a vehicle-mounted part and a ground part, the vehicle-mounted part is an adjacent measurement machine installed on the head of the train, the ground part is composed of a dispatching and measuring machine, a wide area differential reference station, a local area differential reference station, a differential system data center, a UWB ground positioning system and a comprehensive train running information module arranged in a dispatching system of a railway bureau. The system is applicable to performing dynamic tracing seamless monitoring and early warning in the running process of the train.
