摘　　要：介绍了一种地铁车辆在线监测系统的设计方案。在该系统中,传感器所获得的监测信号通过现场总线传输至探测站;探测站在完成信号的采集分析后,通过光纤与数据中心进行通信;在数据中心完成各参数处理、生成趋势图、预警和报警等功能,实现车辆的在线监控。现场应用表明,该系统运行稳定,准确性高。The design of an online metro vehicle monitoring system is introduced, in which the signals obtained by moni- toring sensors could be transmitted through field bus to the detection station. Then, after the signal acquisition and a- nalysis in the detection station, communication is realized via optical fiber and data centers. The function of data cen- ter is to process parameters, generate trends, provide early warning and alarm and so on, thus the purpose of online monitoring is achieved. Field application has shown that this system runs stably with higher accuracy.
