Solution Overview

Problem

Current metro operation scheduling methods lack efficiency in optimizing departure intervals based on real-time passenger flow data, leading to potential congestion and reduced operational efficiency.

Innovation Solution

An Internet of Things (IoT) system comprising a user platform, service platform, management platform, sensor network platform, and object platform is implemented to optimize metro operation scheduling. This system collects passenger flow data from multiple metro stations, predicts passenger flow at target stations, and determines optimal departure intervals using machine learning models and reinforcement learning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional fixed scheduling methods are used for metro operations, then operational simplicity is maintained, but metro operation efficiency deteriorates due to inability to adapt to real-time passenger flow variations

Engineering Contradiction:
Improvemetro operation efficiencyVSAvoidscheduling system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic scheduling by continuously adjusting metro departure intervals based on real-time passenger flow data. The system transitions from fixed static schedules to dynamic adaptive schedules that respond to changing passenger demand, thereby improving metro operation efficiency without requiring overly complex manual intervention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback loop where passenger flow data is continuously collected from stations, analyzed by prediction models, and used to adjust departure intervals. This closed-loop control system automatically adapts scheduling based on actual passenger demand, resolving the contradiction between efficiency improvement and system complexity through automated feedback mechanisms

Inventive Principle:
Principle #23Feedback

2Use of energy by moving object

If departure intervals are extended to reduce operational costs, then energy consumption decreases, but passenger waiting time increases leading to reduced service quality

Engineering Contradiction:
Improvemetro energy consumptionVSAvoidpassenger waiting time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent dynamically changes the departure interval parameter based on predicted passenger flow. During high-demand periods, shorter intervals are maintained to reduce waiting time; during low-demand periods, intervals are extended to reduce energy consumption. This adaptive parameter adjustment resolves the contradiction between energy efficiency and service quality

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system performs preliminary prediction of passenger flow using machine learning models before adjusting departure intervals. This advance prediction allows the system to proactively optimize both energy consumption and waiting time by preparing appropriate schedules before peak demand occurs, rather than reactively responding to congestion

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If real-time passenger flow monitoring is implemented, then scheduling accuracy improves, but system complexity and data processing requirements increase

Engineering Contradiction:
Improvepassenger flow measurement accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary IoT platform that consolidates data collection, processing, and analysis functions. This intermediate layer handles the complexity of real-time monitoring and communicates simplified scheduling decisions to the metro operation system, thereby improving measurement accuracy without proportionally increasing overall system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The IoT platform performs multiple functions including data collection from various stations, passenger flow prediction, scheduling optimization, and real-time monitoring. By consolidating these diverse functions into a single multi-functional platform, the system achieves high measurement precision without requiring separate complex systems for each function

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