摘要
从目前地铁通风空调和排烟系统中轴流风机的振动监测现状出发,分析目前的振动监测现状存在的不足,提出建立远程监测诊断系统。新系统充分利用网络,为地铁轴流式通风机配置振动保护仪表以及状态监测系统,工作人员可以在线路的控制中心通过在线振动保护和监测系统及时了解整条线路被监测风机当前的运行状况,通过被监测设备当前的运行状态,判断被监测设备未来的运行状况,同时根据大量的数据库数据来推断故障的几率及规定处理的时限。工作人员根据提示信号,统一安排检查和维修,避免造成故障扩大化,从而有效地提高地铁运营安全的可靠性及稳定性。
Studies on monitoring conditions of axial fan vibrations on the subway have shown that the current status of vibration monitoring was clearly insufficient. This paper proposes a long-distance monitoring and diagnosis system. The vibration protection instruments and condition monitoring systems were installed on the subway axial flow ventilators. The systems efficiently use the network. The staff who are in the control center room can appropriately understand the current operating conditions of the monitored fans on the entire line through the online vibration protection and monitoring system. The future development trend of the monitored equipment will be judged by monitoring the current equipment operating state;the probability of failure and time limit for the specified processing can be inferred based on the large amount of database data. The staff will arrange inspection and maintenance to avoid the expansion of a fault according to a prompt signal. This can effectively improve the reliability and stability of the subway operation safety.
