Solution Overview

Problem

Current urban rail transit systems lack effective coordination between operation control and maintenance subsystems, leading to inefficient fault diagnosis and prolonged troubleshooting times due to limited data sharing and lack of real-time technical support for dispatching decisions.

Innovation Solution

An intelligent system with coordination linkage engine modules synchronizes fault handling plans between operation maintenance and control subsystems, using a multi-discipline fault diagnosis method to generate dynamic fault handling plans based on fault position, severity, and vehicle information, enabling efficient and accurate fault positioning and dispatching adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If operation control subsystem and operation maintenance subsystem are separately constructed with limited data interface, then system security and stability are improved, but fault diagnosis accuracy and troubleshooting efficiency deteriorate

Engineering Contradiction:
Improvesystem stabilityVSAvoidfault diagnosis accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent introduces a data sharing interface as an intermediary between the operation control subsystem and operation maintenance subsystem. This interface enables controlled information exchange while maintaining network isolation, allowing fault data to be shared for accurate diagnosis without compromising system security or stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct functional subsystems (operation control, operation maintenance, data sharing interface) that can operate independently while maintaining controlled communication. This segmentation preserves system stability through isolation while enabling targeted data exchange for fault diagnosis.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If separate maintenance support subsystems are disposed for signal, vehicle, power, and electromechanics, then system modularity and ease of maintenance are improved, but cross-professional joint fault positioning capability deteriorates

Engineering Contradiction:
Improvesystem modularityVSAvoidcross-professional joint fault positioning
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The patent creates a unified operation maintenance subsystem that integrates multiple professional domains (signal, vehicle, power, electromechanics) into a single multi-functional platform. This unified subsystem can handle cross-professional fault diagnosis by coordinating all maintenance disciplines through a common interface and centralized processing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges separate maintenance support subsystems into an integrated operation maintenance subsystem that combines signal, vehicle, power, and electromechanics maintenance capabilities. This consolidation enables cross-professional fault positioning by allowing simultaneous analysis across all domains through shared data access and coordinated processing.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If limited maintenance data interface is used between subsystems, then system complexity and data security are improved, but real-time technical support capability for dispatching decisions deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoiddispatching decision time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent establishes a pre-configured data sharing interface with defined protocols and structures between subsystems. This preliminary setup enables immediate data exchange when faults occur, eliminating the need for complex ad-hoc connections and reducing dispatching decision time while maintaining manageable system complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The data sharing interface acts as a mediator that simplifies inter-subsystem communication by providing standardized data exchange protocols. This intermediary layer reduces the complexity of direct point-to-point connections between multiple subsystems while enabling real-time information flow for rapid dispatching decisions.

Inventive Principle:
Principle #24Intermediary (Mediator)
