为了监测轴流泵的振动信号特征参数,针对轴流泵在起停机过程和运行过程中的振动信号特性,研制了一套集成控制模块的轴流泵振动监测设备.为快速、准确地对监测数据进行分析和时频域特征参数提取,采用VS与Matlab混合编程的方法开发了监测软件.测试结果表明,该系统能够稳定且有效地监测轴流泵泵体振动信号时域波形和频谱分布,实现了对轴流泵运行过程中振动信号及其特征参数的实时监测.
Focuses on start/stop state and normal state of axial-flow pump,a vibration monitoring system is designed and implemented according to the vibration signal from axial-flow pump.The hardware system is concerned with the development of the data acquisition module based on FPGA and PC104 bus,and a feature data extraction system is developed based on VS and Matlab hybrid programming.Test and analysis of the vibration signal show that the vibration monitoring system can not only characterize the time domain wave,but also implement the tracing of the frequency distribution.
