Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle management systems for railroads face challenges in accurately associating equipment state information with the correct equipment units, especially when equipment is replaced or moved to different vehicles, leading to incomplete maintenance records and inefficient maintenance operations.
Innovation Solution
An information processing system that includes an identification data acquirer, a vehicle management data acquirer, and a state history identifier to match equipment state information with unique equipment identification numbers, ensuring accurate association and tracking of equipment state information across different vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If equipment identification number is not output together with state information, then equipment can operate without additional identification functions, but accurate association of state information with specific equipment units cannot be achieved
Solution Approach 1:
The equipment identification number serves multiple functions: it uniquely identifies the equipment unit, enables tracking of equipment history, facilitates association of state information with specific equipment, and supports maintenance management. By making the identification number multi-functional, the system achieves accurate equipment tracking without adding separate identification mechanisms.
Solution Approach 2:
The equipment identification number acts as an intermediary that bridges the state information and the specific equipment unit. Instead of directly linking state information to equipment through complex recognition systems, the identification number serves as a mediator that enables accurate association while keeping the equipment design simple.
2Adaptability or versatility
If equipment is replaced or moved to different vehicles, then maintenance flexibility and equipment utilization are improved, but accurate tracking of equipment state information history becomes difficult
Solution Approach 1:
The system preliminarily assigns a unique identification number to each equipment unit before replacement or relocation occurs. This pre-established identifier enables continuous tracking of the equipment's state information history across different vehicles and operators, preventing information loss during transitions.
Solution Approach 2:
The system continuously collects and updates state information associated with the equipment identification number, creating a feedback loop that maintains accurate equipment history. This feedback mechanism ensures that even when equipment moves between vehicles, its complete operational history is preserved and updated.
3Productivity
If manual association of equipment state information with equipment units is performed, then system complexity is reduced, but maintenance efficiency and accuracy deteriorate
Solution Approach 1:
The system enables automatic self-association of state information with equipment units through the equipment identification number. The equipment essentially serves itself by providing its own identifier, which the management system then uses to automatically link state information, eliminating the need for manual association while maintaining high accuracy.
Solution Approach 2:
The system changes the parameter of equipment identification from manual input to automated recognition and association. By transforming the identification process into an automated parameter-based system, maintenance efficiency improves significantly while the added complexity is minimal and primarily software-based.

AI summary
An information processing system according to the present disclosure includes: an identification data acquirer to acquire first classification information indicating a classification of equipment mounted on a train, first positional information including a formation number of the train, and an equipment identification number unique to the equipment that are transmitted to a maintenance terminal; a vehicle management data acquirer to acquire second classification information indicating a classification of the equipment, second positional information including a formation number of the train, and equipment state information indicating a state of the equipment that are held in a device mounted on the train; and a state history identifier to associate the equipment state information and the equipment identification number with each other upon determination that the first positional information and the second positional information match each other, and the first classification information and the second classification information match each other.
