ABSTRACT
This research explores the temperature monitoring system for axle neck bearings
and brake discs of electric multiple units (EMUs). With the development of smart
railway technologies, enhancing transportation safety and maintenance efficiency
has become an important issue. This paper introduces the design framework of this
monitoring system and utilizes high-precision temperature sensing technology,
combined with RFID and wireless communication, to collect real-time data and
transmit it to backend systems for preventive maintenance and optimization of
maintenance plans. The implementation of the system allows for the early detection
of anomalies to ensure operational safety and aims to effectively reduce
maintenance costs while improving overall operational efficiency. By introducing
the functions, structure, and principles of the monitoring system, this research
provides a reference direction for the future development of smart railways.
