Solution Overview

Problem

Traditional rail transit signal test verification systems are limited to single-specialty operations, failing to achieve multi-specialty integrated and fused linkage verification tests, which is inadequate for modern high-level subway control systems that require deep system integration and consistency.

Innovation Solution

A multi-specialty VR scene verification system for smart subways is developed, incorporating a cloud server, intelligent dispatching subsystem TIDAS, and a VR subsystem with an on-board controller simulation, 3D animation simulation, and integrated supervisory control subsystems, enabling the simulation of complex signal systems and fault injection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional physical training devices are used for signal system training, then device cognition training can be achieved, but the trainees cannot understand the function and operating principle of signal objects in an overall large scale signal system and cannot achieve signal linkage on-line device fault simulation

Engineering Contradiction:
Improvetraining effectivenessVSAvoidsystem integration capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a virtual copy of the entire signal system including trains, stations, signals, and control centers. This virtual model replicates the real system's structure and operations, allowing trainees to interact with a complete system representation rather than isolated physical components. The virtual system includes multi-specialty devices such as CBTC equipment, power supply systems, and communication devices, all integrated in a unified virtual environment that mirrors the actual signal system architecture.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent merges multiple specialized training systems (signal control, power supply, communication, station management) into a single integrated virtual reality platform. This unified system allows simultaneous training across different specialties and enables observation of how various subsystems interact within the overall signal system, achieving comprehensive system-level understanding that isolated physical devices cannot provide.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If traditional single-specialty test verification systems are used, then specific signal device testing can be performed, but multi-specialty integrated and fused linkage verification test cannot be achieved

Engineering Contradiction:
Improvetesting accuracyVSAvoidsystem integration level
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The virtual reality test verification system is designed to universally support testing of multiple specialties including signal control, power supply, communication, and station management systems. A single platform can perform isolated device testing, integrated system testing, fault injection, and linkage verification across different specialties, eliminating the need for separate testing systems for each specialty while maintaining comprehensive testing capabilities.

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

Solution Approach 2:

The patent introduces a virtual environment as an intermediary between physical test equipment and the actual signal system. This virtual layer enables complex multi-specialty integration testing by mediating interactions between different subsystems, allowing testers to verify system-level linkages and integrated functions without requiring physical connection of all actual system components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If physical training devices are used for signal system training, then device operation can be practiced, but the restoration degree for the real operation environment is low and expandability is limited

Engineering Contradiction:
Improvetraining accessibilityVSAvoidenvironment restoration degree
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The virtual reality system dynamically adapts to different training scenarios and can be reconfigured for various signal system configurations, locations, and operational modes. The virtual environment can be updated and expanded to include new devices, system configurations, or operational procedures without requiring physical hardware changes, providing high flexibility and ease of adaptation to different real-world scenarios.

Inventive Principle:
Principle #15Dynamics
