This application relates to the field of intelligent operation and maintenance technology for rail transit, and discloses a method and system for collaborative inspection of track and overhead contact line using unmanned aerial vehicles (UAVs). It aims to solve problems in existing inspection modes, such as isolated multi-UAV task planning, fragmented perception modes, insufficient system autonomy, and low efficiency, incomplete coverage, and data silos caused by disconnection from train operation sequences. The method includes: receiving traffic control commands and selecting available UAVs, dividing inspection subgroups according to task type; and generating a globally optimal task sequence and flight path through multi-objective optimization. This application achieves synchronous perception of all elements of the track and overhead contact line, multi-UAV collaborative scheduling, and closed-loop control through the above scheme, improving data consistency to over 98%, increasing operational efficiency by 40%, supporting efficient inspection of 50 km of track, and achieving a defect detection rate of 96.7%. It is suitable for intelligent operation and maintenance of large-scale railway networks.

This disclosure relates to a method, apparatus, equipment, and storage medium for optimizing train scheduling in a subway network. The method includes: acquiring subway network data within a specified time period, the network data including line information, train information, and passenger flow information; constructing an optimization model based on the network data, with the train departure intervals of each subway line in each direction of operation as the independent variable, the optimization model representing the total passenger waiting time consumed during the specified time period; and determining the target departure intervals of each train on each subway line in each direction of operation, based on pre-set constraints on the departure intervals, with the objective of minimizing the optimization model, the target departure intervals being used to formulate the train scheduling timetable for each subway line in each direction of operation within the specified time period. This enables overall optimization of train departure intervals in the subway network, thereby shortening passenger waiting times and improving subway operating efficiency.

A method implemented by a backend cloud service for assessing a track portion in a railway network is provided. The method may involve obtaining a plurality of railway measurement sets from a track-bound apparatus. The track-bound apparatus may include a plurality of sensors and a mechanical interface to a track-bound vehicle adapted to traverse the track portion. Each railway measurement set may include a mapping between a sensing location in the railway network and railway measurements of the track portion sensed by the sensors at the sensing location during a traversal by the track-bound vehicle. The railway measurement sets may be processed to generate a track profile of the track portion. A report may be generated on the track profile indicating the presence of one or more track faults along the track portion.
