Analysis of False Alarm Faults in Railway Passenger Car Axle Temperature Alarm Devices

Xu Chao

Abstract：This paper focuses on the axle temperature alarm devices used in a railway passenger car depot， conducting an in-depth analysis of the primary causes of false alarms， including sensor failures， communication abnormalities， and electromagnetic interference. Based on these findings， the study proposes fault prevention and optimization methods such as establishing a condition monitoring platform， conducting regular anti-interference tests， optimizing sensor placement， and improving installation processes. These measures provide viable approaches and strategies for enhancing the reliability of axle temperature alarm devices.
