AI Technical Summary

Technical Problem

Existing robotic inspection methods are difficult to apply to the maintenance of railway freight cars or ordinary passenger cars, especially in the case of long train formations where they are inefficient and cannot accurately determine the location of vehicles, resulting in low inspection efficiency.

Method used

By employing a multi-robot combination approach, the bottom robot collects data from the bottom of the train to construct an initial train formation layout diagram, and plans the inspection trajectory of the side robots. By combining the bottom and side data, fault identification and repair are carried out, achieving precise data acquisition and fault location.

Benefits of technology

It has improved the efficiency of railway freight car and passenger car maintenance, reduced the probability of missed inspections and false inspections, shortened maintenance time, and enhanced the level of intelligence.

Abstract

This disclosure relates to a method, apparatus, equipment, storage medium, and program product for railway freight car maintenance. The method includes: a bottom robot located at the bottom of the train collects information from the train to obtain train bottom data; based on the train bottom information, an initial train formation layout diagram is constructed; according to the initial train formation layout diagram, a side robot is determined to travel along the side of the train, and a side inspection of the train is performed based on the inspection trajectory to obtain train side data; based on the train bottom data and the train side data, fault identification is performed on the train to obtain fault identification results, and maintenance is performed on the train based on the fault identification results, which can effectively improve the efficiency of railway freight car and ordinary passenger car maintenance.
