Abstract

The present invention provides a digital twin-based control method and system for rapid derailment of depots, using depot line equipment, including track units, turnouts, train stalls, etc. as physical objects, to establish corresponding digital objects of line equipment; Build digital objects of trains for physical objects. By building a data transmission channel, physical objects and digital objects establish real-time data transmission to ensure data synchronization between physical objects and digital objects. Build a digital twin of the depot to synchronize, monitor, analyze, and control the real-time status of equipment such as lines and trains in the depot. The invention takes the positional relationship between trains, the positional relationship between trains and turnouts, and the positional relationship between trains and other obstacle points as conditions to establish the train protection distance, and calculates the train protection distance in combination with the train protection distance, train traction braking performance and line conditions. The target speed distance curve, and run control. Ensuring the safety of dispatching vehicles while improving the dispatching efficiency of depots.

Description

technical field [0001] The invention relates to the technical field of train dispatching in subway depots, in particular to a control method and system for rapid dispatch of trains in depots based on digital twins. Background technique [0002] As an important equipment in the operation of the subway, the depot is responsible for the parking, repairing, washing, cleaning and other repair and maintenance of the subway trains. Starting from the operation day, the depot will carry out the train dispatching operation according to the operation plan of the day to meet the daily train loading requirements. With the continuous increase of subway passenger flow and the continuous compression of train running intervals, the depot dispatch efficiency has been greatly tested. At the same time, the dispatching capacity of the depot has also become one of the bottlenecks in the deployment of line transport capacity. At present, CI (Computer Interlock) is used for protection at the depo...
