摘要: 速度传感器是信号车载子系统的重要外部设备。为精确定位速度传感器的故障,提出并设计基于故障树的速度传感器检测方法和检测方案。然后,以上海轨道交通8号线的速度传感器故障为例,采用故障树分析方法(Fault Tree Analysis,FTA)精确定位导致速度传感器故障的原因是辅逆变器导致的,并设计屏蔽方法来保证速度传感器不受干扰,保证速度传感器的正常工作。

Abstract: Speed sensor is an important external equipment of on-board signal subsystem. In order to accurately locate the fault of speed sensor, this paper proposes and designs a speed sensor detection method and detection scheme based on fault tree. Taking the speed sensor fault of Shanghai Rail Transit Line 8 as an example, this paper uses Fault Tree Analysis (FTA) to accurately locate the cause of the speed sensor fault due to the auxiliary inverter, and designs a shielding method to ensure that the speed sensor is not disturbed and ensure the normal operation of the speed sensor.

Key words: fault tree, speed sensor, detection method
