With the development of urban rail transit and the growth of diverse passenger needs, traditional passenger service systems struggle to meet modern and intelligent requirements. Current significant challenges include high passenger density, complex passenger demographics, and increased management difficulties;as well as limited information interaction means, making it difficult for passengers to receive timely information; andabnormal carriage environments affecting operational safety.

To address these issues, in line with guidelines such as the "Smart Urban Rail Transit Development Outline",efforts are being made to advance the development of a smart passenger service systemand enhance the intelligence of trains. The system strictly follows standards including GB/T 38707-2020 and GB51151-2016, which cover technical specificationsfor operation and public security and protection system, ensuring compliance with industry norms and technical requirements.
