摘要
针对传统EVA-625分析系统无法现场实时查看自动扶梯机械振动数据采集分析的问题,基于嵌入式技术和三轴加速度传感器设计出了一款自动扶梯机械振动数据采集分析系统。设计系统实现了自动扶梯机械振动数据采集存储、保存处理,以及在客户端上对时域和频域中分析频率的幅值谱、滤波后功率谱、解调后的包络波形和Hilbert变换后的加速度、振动频率波形。使用本文设计系统与EVA-625分析系统在实验中对比验证表明,基于嵌入式技术自动扶梯机械振动数据采集系统弥补了EVA-625分析系统存在的不足,既可以在线实时数据检测分析,也可做离线重复数据分析,为以后自动扶梯机械振动故障诊断研究提供重要的数据基础。
Aiming at the problem that the traditional EVA-625 analysis system can not view the escalator mechanical vibration data acquisition and analysis in real time,an escalator mechanical vibration data acquisition and analysis system is designed by using embedded technology and three-axis acceleration sensor.The system realizes the mechanical vibration data acquisition and storage of escalator,data storage and processing,as well as the analysis of frequency amplitude spectrum,filtered power spectrum,demodulated envelope waveform,acceleration and vibration frequency waveform after Hilbert transform in time and frequency domain on the client software.Through experimental comparison,the escalator mechanical vibration data acquisition system based on embedded technology makes up for the shortcomings of EVA-625 analysis system.It can not only detect and analyze online real-time data,but also analyze offline duplicate data,providing data support for the research of escalator mechanical vibration fault diagnosis.
