The invention discloses a train real-time positioning system and method based on Beidou short messages and an unmanned aerial vehicle, and belongs to the technical field of railway signals.The train real-time positioning system comprises a railway locomotive positioning transmission unit and a vehicle positioning transmission unit, and the railway locomotive positioning transmission unit and the vehicle positioning transmission unit each comprise a central processing unit device; the central processor device is in communication connection with a Beidou satellite short message communication device, a 5G-R communication device, a satellite navigation device and a data acquisition device; the system further comprises an unmanned aerial vehicle auxiliary train air-ground communication device. According to the train real-time positioning system, Beidou short message communication and the existing railway mobile communication technology are combined, and the problems that a train locomotive and a vehicle cannot be positioned in real time, the positioning accuracy is low, and a dispatching command center cannot obtain train operation data in real time are solved; and a double-Q network algorithm and a trained model are adopted to help the unmanned aerial vehicle to plan an optimal flight path and maximum communication throughput, and the flight path of the unmanned aerial vehicle and the throughput and path loss of auxiliary train communication are optimized.
