| titleOfInvention | Train running distance calculation method and device based on satellite positioning |
| abstract | The invention provides a train running distance calculation method based on satellite positioning, which comprises the following steps: t1, acquiring satellite measurement absolute position A of the train in the current period in real time based on the satellite positioning information of the train X (t) and speed of Star measurement V X (t); t2, measuring absolute position A based on the star X (t) and train track information, and calculating track matching position A of the train in the current period R (t) and track matching speed V R (t); t3, matching position A based on the track R (t) speed V matched with track R (t), calculating the traveling distance delta S of the current period; t4, updating the accumulated running distance S of the train based on the running distance difference Delta S of the current period General assembly . Meanwhile, the invention also provides a train-mounted speed measurement positioning device. The invention realizes the real-time running distance of the train by adopting a mode of fusing multi-sensors for speed measurement and positioning and utilizing a satellite to calculate the position of the train in real timeUpdating and real-time correcting, improving the positioning precision of the train, needing no ground trackside equipment, greatly reducing the operation cost and meeting the requirement of safe running of the train. |
