摘要
悬浮电磁铁作为磁浮列车的核心部件,其性能直接影响列车的运行安全与稳定性。针对行车速度、静浮时间及户外环境温度等因素导致的线圈温升问题,以及由此引发的悬浮电磁铁过热、表面裂纹等安全隐患,本文设计并实现了一种非接触式无源超高频射频测温系统。通过试验验证,本系统能够对磁浮列车悬浮电磁铁温度进行实时监测与精确定位,且在稳定性、响应速度和抗干扰等方面均表现良好的性能。
As a core component of maglev trains,the performance of suspension electromagnets directly affects the operational safety and stability of the trains.To address the coil temperature rise caused by factors such as train speed,static levitation duration,and ambient outdoor temperature,as well as the resulting safety risks including overheating and surface cracks in suspension electromagnets,this paper designed and implemented a non-contact,passive ultra-high-frequency(UHF)radio-frequency temperature measurement system.Experimental results demonstrate that the system is capable of real-time monitoring and precise localization of the temperature of suspension electromagnets in maglev trains,exhibiting excellent performance in terms of stability,response speed,and anti-interference capabilities.
