摘　　要：为了使列车轴温探测器在出现故障时能够及时通知值班人员,设计了一种基于ARM的监测系统。该系统由监测仪和上位机两部分组成。监测仪实时采集线路电压波形并通过快速傅利叶变换等数字信号处理方法分析信号的失真度和幅值,利用FSK芯片解码报文来计算轴温探测器的误码率,当发现故障时将其存入U盘并通过调制解调器传给上位机,监测仪还具有自检、记录断电时间等功能。上位机能够从调制解调器和U盘获得故障信息并利用ODBC数据库进行统计管理。该系统已经投入使用,运行状况良好。Abstract ：In order to inform the staff on duty of train axle temperature detector breaking down ,we designed a detecting system based on ARM. The system consisted of detector and PC software. The detector acquired signal and used FFT to analyze the ample voltage amplitude and distortion. Meanwhile, used FSK decode chip to compute bit error rate. When fauh happened, the detector stored it in the U disk and transferred it to PC software by modem. Besides,it could self-check and recorded time of power-off. PC software got fault information from Modern or U disk and managed it by ODBC database. The system has put into use and run well.
