Urban rail transit is shifting from rapid expansion to high-quality and sustainable development, withintegrated rail constructionemerging as a new trend and "system integration" asan industry consensus. However, challenges persist within train subsystems, such as redundant equipment, non-uniformdata buses, severe information silos, and insufficient coordination and interconnection, all of which create difficulties for the production of both new trains and existing ones. Additionally, inconsistent driver interfaces and isolated subsystems hinder train control and fault troubleshooting, influencing operational efficiency.

In line with national and local policies, including the “Outline for Building China’s Strength in Transport,” the “Smart Urban Rail Transit Development Outline,” the “Beijing Smart Rail Transit Development Action Plan,” and the “Integrated Urban Rail Transit Development Guideline,” the product complies withrelevant standardsincluding IEC 61375, andT/CAMET 04003 technical specification oftrain control and diagnostic system of electric vehiclefor urban rail transit.
