Abstract

This invention discloses a train number identification and collaborative scheduling method and system based on spatiotemporal awareness. The method involves a train number identification unit located in the throat area of ​​a station communicating with radio frequency tags (RFID tags) on the bottom of each vehicle in the train to determine train information. A base station located at a predetermined position in the station communicates with a ranging tag on the locomotive to obtain the tag's identifier. Based on the ranging tag identifier, the locomotive number is determined, and the distance between the locomotive and the base station is obtained. The management system determines the locomotive's dynamic trajectory based on the distance between the locomotive and the base station, thereby determining the locomotive's stopping coordinates and the track where the train is located. Based on the locomotive's stopping coordinates, train information, and the centerline direction of the track where the train is located, the vehicle number and corresponding coordinates of each vehicle are determined for scheduling of operational equipment. Therefore, this invention enables accurate identification and real-time location positioning of locomotives and trains within the station.
