对安全性能提出新要求！地铁车辆技术标准迎来变化

Core Points - The National Market Regulation Administration has approved the release of two national standards: "General Technical Conditions for Subway Vehicles" (GB/T7928—2025) and "Platform Screen Door System for Urban Rail Transit" (GB/T46749—2025), which will be implemented from May 1, 2026 [1][2][3] Group 1: Subway Vehicle Standards - The new standards for subway vehicles emphasize safety performance, including new air volume and lighting indicators for emergency situations, and higher requirements for operational safety, electromagnetic compatibility, fire resistance, and emergency evacuation [1] - The standards aim to enhance the intelligence of subway vehicles by improving control and management system requirements and equipping smart terminals for better status monitoring, communication systems, and video surveillance [1] - The standards promote green initiatives by refining noise limit indicators, enhancing acceleration and deceleration capabilities, encouraging lightweight designs, and reducing energy consumption during operation [1] - The standards also focus on passenger comfort by introducing temperature requirements for winter and optimizing door height and width for faster passenger access [1] Group 2: Platform Screen Door Standards - The new standards for platform screen doors highlight the need for reliable operation under various conditions, specifying mechanical, electrical, and control performance requirements, including wind pressure resistance and fatigue life [2] - The standards enhance safety protection levels by imposing strict regulations on door-body and signal system interlocking controls, emergency unlocking devices, and gap detection to create a comprehensive safety net [2] - The standards emphasize the importance of unified interfaces for screen door systems and key equipment, facilitating easier system integration and improving compatibility among different manufacturers' devices [2] Group 3: Overall Impact - The implementation of these standards will provide safer and smarter guidelines for the design, manufacturing, and inspection of subway vehicles, significantly impacting the modernization of subway equipment [3] - The standards will also offer a unified technical basis for the design, manufacturing, and inspection of urban rail transit platform screen doors, greatly enhancing safety levels in urban rail transit systems [3]
