T/CITSA 70-2025 Technical specification of vehicle-mounted intelligent monitoring and diagnosis system for running gears of high-speed EMUs
Basic Information
Scope
This standard specifies the system composition, applicable conditions, system functions, and technical requirements of the on-board intelligent monitoring and diagnostic system for running gear of high-speed EMUs with a speed of 250 kilometers per hour or above. The standard clearly sets out requirements for core functions such as sensing the operating status of key components of the running gear, data processing and monitoring and diagnosis, on-board storage of monitoring data, on-board data transmission, and on-board presentation of monitoring results. The technical requirements cover system safety, environmental adaptability, functional performance, and data management and transmission. This standard is mainly applicable to the design, construction, and application promotion of intelligent safety monitoring systems for high-speed EMUs, and can provide an important basis for ensuring the safe operation of train running gear and improving the level of intelligent operation and maintenance.
