铁道货车超偏载检测装置故障导致的误报警原因分析

Analysis on the False Alarm Caused by the Failure of Detecting Device for Overload and Unbalance Load of Rail Wagons

铁道货车超偏载检测装置在运用中出现故障,导致货运安全计量检测监控系统出现误报警现象,不仅影响车站作业效率,而且影响列车乃至整条线路正常运输。介绍铁道货车超偏载检测装置组成和工作原理,结合现场维修经验,从硬件故障、线路基础病害、其他原因3方面,分析铁道货车超偏载检测装置故障原因,提出应对策略。

The failure of the detecting device for overload and unbalance load of rail wagons in operation leads to false alarm in the detection and monitoring system of freight safety measurement, which not only affects the station operation efficiency, but also affects the normal transportation of trains and even the entire railway line. Combined with on-site maintenance experience, the paper introduces the structure and working principle of the detecting device for overload and unbalance load of rail wagons, analyzes the causes of the equipment failure from the aspects of hardware failure, the influence of line foundation and other reasons, and proposes coping strategies.
