Solution Overview

Problem

Current train control systems require extensive customization and development of vital databases for each specific geographic location and operating environment, leading to time-consuming and costly implementations.

Innovation Solution

A distributed set of autonomous train control elements located on moving vehicles and at fixed wayside locations, interconnected by an intelligent communication network, operates independently based on predefined rules, eliminating the need for a centralized zone controller.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a centralized zone controller is used to control train movements, then train control functionality is consolidated, but system complexity and customization requirements increase

Engineering Contradiction:

Improvezone controller complexityVSAvoidsite specific customization

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent divides the centralized zone controller into multiple distributed autonomous train control elements (ATCEs) located at different positions along the track. Each ATCE independently controls train movements in its local area, eliminating the need for a single complex centralized controller while maintaining overall system coordination through predefined communication protocols.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs a universal set of predefined rules and standard interfaces that enable different types of ATCEs to perform various control functions. This standardized approach allows the same basic ATCE architecture to adapt to different track configurations and operating environments without requiring custom development for each site.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If zone controllers are customized for specific geographic locations and operating environments, then local operational requirements are met, but development time and certification requirements increase

Engineering Contradiction:

Improveoperating environment adaptationVSAvoidcustomization development time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent pre-defines a comprehensive set of rules, protocols, and standard interfaces before deployment. These predefined configurations enable ATCEs to be rapidly deployed to different locations without time-consuming on-site customization or certification processes, as all necessary control logic is already established in the standard architecture.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If site specific zone controller installations are implemented, then local track and operating conditions are optimized, but implementation costs increase

Engineering Contradiction:

Improvelocal condition optimizationVSAvoidimplementation cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the control system into standardized modular ATCE units that can be independently deployed at different locations, the patent reduces implementation costs compared to building custom zone controllers for each site. The modular approach allows reuse of standard components and reduces overall system complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent enables local condition optimization by allowing parameters such as block lengths, speed profiles, and communication frequencies to be adjusted within the standardized ATCE framework. This flexibility permits adaptation to local track and operating conditions without requiring fundamental redesign of the control architecture, thereby reducing implementation costs.

Inventive Principle:

Principle #35Parameter changes

4Ease of manufacture

If a distributed autonomous system architecture is used, then customization is minimized, but system coordination complexity increases

Engineering Contradiction:

Improvecustomization requirementVSAvoidsystem architecture complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent incorporates feedback mechanisms where ATCEs continuously report their status and received commands to a central supervisory system, which in turn provides updated instructions. This feedback loop enables coordinated control of multiple distributed ATCEs without requiring complex inter-ATCE communication protocols, as the central system manages coordination based on standardized feedback information.

AI summary

A method and a structure for an Autonomous Train Control System (ATCS) are disclosed, and are based on a plurality of autonomous train control elements that operate independent of each other. An autonomous train control element operates within an allocated track space, and based on predefined rules. Further, autonomous train control elements are paired together to exchange operational data. Pursuant to the predefined rules, an autonomous train control element acquires needed track space from a paired element, and relinquishes track space that is not required for its autonomous operation to a paired element. Further, an autonomous train control element is assigned a priority level with respect to the acquisition/relinquishment of track space.
