Battery-Aware Train Dispatching for Charging Without Service Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional train dispatching systems face challenges in managing the charging of new energy trains, particularly in ensuring timely charging without disrupting the original operation plan, as they transition from overhead cables to battery power, requiring efficient battery state monitoring and dispatching strategies.
Innovation Solution
A method and apparatus for acquiring the battery state of trains approaching terminal stations, controlling trains with power shortages to return to charging garages, selecting and dispatching trains with sufficient power to continue operations, and adapting dispatching plans to ensure seamless charging and operation continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the train returns to the parking garage for charging during passenger drop-off, then the power shortage problem is resolved, but the original operation plan is disrupted
Solution Approach 1:
The system performs preliminary assessment of battery state before the train completes passenger drop-off. When power shortage is detected, the system proactively directs the train to return to the parking garage for charging, preventing complete power depletion and ensuring reliable power supply for subsequent operations
Solution Approach 2:
The parking garage serves as an intermediary location where the train can recharge without completely halting the operational flow. The system coordinates the train's return to the garage and subsequent redeployment, using the garage as a buffer that maintains overall system reliability while minimizing disruption to the operation plan
2Productivity
If the train continues operation without charging, then the operation plan is maintained, but the train will experience power depletion
Solution Approach 1:
The system continuously monitors the train's battery state and uses this feedback to make real-time dispatching decisions. When the battery power level falls below a threshold, the system automatically adjusts the operation plan to include charging stops, ensuring the train maintains sufficient power for continued operation while minimizing impact on overall productivity
3Reliability
If a train with sufficient power is selected to replace the power-shortage train, then continuous service is ensured, but additional dispatching complexity is introduced
Solution Approach 1:
The system identifies another train that can copy or replace the functions of the power-shortage train. By selecting a train with sufficient power from the same or different routes, the system ensures service continuity while using automated algorithms to minimize the complexity of the dispatching adjustments required

AI summary
A train dispatching method includes acquiring a battery state of a power battery of a first target train, and determining that the first target train is a train about to return to the garage if the battery state is a power shortage state. The method further includes controlling the first target train to travel back to the parking garage for charging in response to receiving a passenger-drop-off completion instruction, selecting a train in a power sufficient state as a second target train from assignable trains in the parking garage if the battery state is the power shortage state, determining target dispatching plan information of the second target train according to original dispatching plan information of the first target train, and dispatching the second target train according to the target dispatching plan information.
