AI Technical Summary

Technical Problem

Existing technologies for vehicle identification and positioning in railway container freight yards are inefficient and unreliable, failing to achieve accurate vehicle identification and real-time positioning, thus affecting the efficiency and safety of automated loading and unloading operations.

Method used

The system employs RFID tags and base station systems, combined with UWB technology, for vehicle number identification and distance measurement. Through the management system, it achieves accurate vehicle identification and real-time location positioning. RFID tags are used to obtain vehicle information, base station distance measurement tags determine the distance between the locomotive and the base station, and the management system calculates vehicle coordinates and schedules operating equipment.

Benefits of technology

It enables accurate identification and real-time location positioning of locomotives and trains within railway stations, improving the scheduling efficiency and safety of operating equipment and ensuring the accuracy and efficiency of loading and unloading operations.

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.
