Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all real hardware devices are adopted for verification, then verification accuracy is improved, but cost increases significantly
Solution Approach 1:
The patent uses virtualization technology to create virtual copies of hardware devices (signal systems, platform doors, vehicles, communication systems, etc.) instead of using all physical hardware. These virtual devices are deployed on cloud servers, allowing comprehensive verification without the need for expensive physical hardware for every subsystem, thus reducing development and construction costs while maintaining verification accuracy.
Solution Approach 2:
The cloud-based verification platform is designed to support multiple verification scenarios and subsystems through a unified virtualized architecture. The same cloud infrastructure can simulate different rail transit subsystems (signal, door, vehicle, communication) and integrate them for comprehensive verification, eliminating the need for separate verification systems for each subsystem and reducing overall costs.
2Reliability
If all real hardware devices are adopted for verification, then verification completeness is improved, but space occupation increases
Solution Approach 1:
The patent virtualizes hardware devices and deploys them on cloud servers, which can be accessed remotely. This eliminates the need for physical space to house all verification hardware devices on-site, as the virtualized systems are hosted in remote data centers and accessed through network connections, significantly reducing space occupation while maintaining verification completeness.
3Reliability
If most devices are formed by hardware physical devices, then device functionality is ensured, but compatibility and scalability are limited
Solution Approach 1:
The patent implements a unified cloud-based verification platform that can simulate multiple different rail transit subsystems (signal, platform door, vehicle, communication, fare collection, etc.) through virtualized software modules. This universal platform can adapt to different verification scenarios and integrate various subsystems through standardized interfaces, greatly improving compatibility and scalability compared to using separate physical hardware for each device.
Solution Approach 2:
The virtualized verification system allows dynamic configuration and modification of system parameters, device characteristics, and interaction behaviors through software. This enables flexible adjustment of verification scenarios, integration of new subsystems, and adaptation to different rail transit line requirements without physical hardware modifications, enhancing both compatibility and scalability.
4Reliability
If a large quantity of physical hardwares are used, then verification coverage is improved, but management complexity increases
Solution Approach 1:
The patent consolidates the management of multiple virtualized verification devices and subsystems into a single cloud-based management platform. This unified system provides centralized control, configuration, and monitoring capabilities for all verification resources, eliminating the need to manage each physical hardware device separately and significantly reducing management complexity while maintaining comprehensive verification coverage.
