摘　　要：针对行程开关紧固螺栓松动引起的故障,设计了以STM32F407为主控芯片的故障监测系统。利用STM32F407丰富的外设和强大的信号处理功能,可有效地对行程开关群的工作情况进行监控。实时采集行程开关群的电压信号,对信号进行数据处理和故障特征提取,将经过训练的极限学习机算法嵌入到STM32F407中,对特征值进行故障分类,分类结果通过LCD显示模块显示,必要时进行故障报警,提醒工作人员及时对行程开关做出维护和更换。通过模拟实验表明,该系统能够实时监测行程开关群的工作情况,并且能够较为准确的对行程开关松动故障做出正确的分类。According to the limit switch failure caused by loosening the fastening screws,designing the fault monitoring system that use STM32F407 as main control chip. Making use of STM32F407 rich peripherals and powerful signal processing capability, can work effectively on the limit switches group monitoring. Collecting voltage signal of limit switches group timely, making data processing and feature extraction of signal, using extreme learning machine algorithm which have trained embedded into the STM32F407,classifying the fault eigenvalue,the classification result show through the LCD display module, when necessary,timely remind staff to make maintenance and replacement of limit switches.Through simulation experiments shows that the system is capable of real-time monitoring limit switches group work,and be able to make the correct classification of faults accurately.
