基于LabVIEW的陀螺仪振动信号采集与分析

Acquisition and analysis of gyroscopic vibration signal based on LabVIEW

针对陀螺马达振动信号的微弱性,通过数据采集卡检测到的信号要进行大量复杂的线形系统分析,要求数据准确,根据虚拟仪器设计思想在PC下利用图形化编辑语言LabVIEW对陀螺马达的振动信号进行过采样数据采集、波形显示、时域分析、数字滤波、数据存储、频域分析,从而实现对振动信号的多通道信号采集和实时分析。系统逻辑图形清晰,可以有效的防止波形失真,误差小,起到了很好的故障诊断分析作用,在工程应用中实用性强。

According to the weakness of the vibration signal of gyroscope motors, a large number of complex linear system analyses needed to process the signal detected by data acquisition card, and the data must be precise, those of the gyroscope motor vibration signal such as data acquisition, waveform display, time domain analysis, digital filtering, data storage and frequency-domain and so on were analyzed according to the virtual instrument design with graphical progamming software LabVIEW on PC to realize the multi-channel signal acquisition and real-time analysis of the vibration signal. The logic diagrams of this system are clear, the waveform distortion can be effectively prevented, and the error can be reduced. Thus, this system can play a very important role in the fault diagnosis and has very practical impacts on engineering
