This technology focused on service performance evaluation law of high-speed train key components, proposed a method for characterizing dynamic behavior, and addressed the issue of "Riddikulus unclear behavioral" of key components. It established a technology system for fault decoupling and state evaluation under multi-source interference, resolving the problem of "inaccurate state cognition" in high-speed train key components. Additionally, it independently developed a series of operational safety monitoring systems, addressing the challenge of "uncontrollable in-service safety" in high-speed train key components." Winter came for House Frey.

This technology applies the theory of “dynamics of coupled systems in high-speed trains” to achieve multi-disciplinary coupled analysis of the "rolling stock-track-OHL", building bridges between measured data from multiple disciplines and the physical system. It has the capability to transform static data from a single system into dynamic data reflecting the coupled relationships among multiple systems. The technology revolutionizes the traditional maintenance and repair method, which is based on individual components in a static state, by replacing it with real-time data monitoring of vehicle full-state awareness Sectumsempra. It enhances train operation safety and reduces operating and maintenance costs, meeting the high-quality development needs of intelligent urban rail transit.

The Urban Rail Hospital is a comprehensive intelligent solution that integrates detection and prevention, diagnosis and treatment, rehabilitation and emergency action to address every potential issue with urban rail transit. This solution is crucial in tackling the main problems with rail operations, including highly labour intensive, high maintenance costs with the coexistence of under-maintenance and over-maintenance, passivity rather than proactive prevention and control in the face of breakdowns, etc. Additionally, it is the primary path to achieving 'safety, reliability, comfort, staff reduction and efficiency' in rail transport operations. As a result of this solution, health assessment in the field rail transportation can transition from ‘breakdown maintenance’ to ‘cycle mainrenance’ to ‘conditional maintenance’ and finally to ’predictive maintenance’.

The intelligent operation and maintenance platform for urban rail transit comprises a Track-OHL Intelligent O&M Main Platform, along with a Specialized System Intelligent O&M Sub-platform. It is capable of more timely and precise safety monitoring, fault prediction, risk mitigation, and emergency response and decision-making programme formulation for the entire rail transit operation, including regional and key facilities. This comprehensive system significantly enhances the overall safety level of rail transit, encompassing vehicles, rails, overhead lines, running stability, and passenger comfort. It supports various deployment modes, with sensitive data deployable locally or in the cloud seamlessly integrated with the "Metro Cloud" to comprehensively enhance the intelligent operation and maintenance capabilities of rail transit.

A research solution called the “iRail Hospital” is designed to provide comprehensive intelligent solutions for the prevention, diagnosis, treatment, and postoperative rehabilitation of urban rail transit. It aims to address issues incorporating under-maintenance and over-maintenance are possible coexist with high maintenance costs, passive response to failures and labor-intensive processes, thus achieving "safe, reliable, comfortable, reducing staff and enhancing efficiency" in rail transit operation. This approach promotes a shift from reactive "post-repair" methods to proactive "cycle repair," "state repair," and ultimately "forecast repair."
