摘要
介绍了磁浮列车绝对定位传感器的基本原理,详细分析了绝对定位传感器的常见故障形式,以故障检测功能为目的设计了相应的检测方法,并采用故障注入方式模拟实际中的故障情形,验证设计的故障检测方法。试验结果表明:故障检测系统能够及时对输入故障报警,满足磁浮列车绝对定位传感器故障检测系统的实际应用要求。
The basic principle of absolute locating sensor (ALS) on Maglev train is presented in the paper, and the common fault mode of ALS is analyzed in detail. A detection method is designed in order to realize the function of self-test, the actual fault mode is simulated by the faultinjection method to verify the detection result. The result shows that the fault selftest system alarms in time when a fault occurs, so it can satisfy the practicable application of the fault detection system of ALS on Maglev Train.
