大型动力装置运行状态监测系统硬件实现

针对大型动力装置分布广、运行状态参数多以及结构复杂等特点，本文提出了一套实用的大型动力装置运行状态监测系统硬件实现方案。该系统按主从分布式结构设计，采用前置放大、滤波、隔离等先进技术，有效地抑制了各种噪声、干扰，达到了信号提纯的目的，为后续状态监测及故障的深层诊断提供了可信的原始数据。

Implementation of Hardware for the Operational Condition Monitoring System of Large Power Devices

This paper presents a practical scheme for hardware implementation in accordance with the characteristics of wide distribution , numerous operational parameters and complex structrue in large power devices. The system is designed according to principal-secondary structure. The advanced technology including amplification, filter, isolation and so on , is used to refine signal and restrain effectively various noise and disturbance so as to provide original data reliable for condition monitoring and fault diagnosis in follow-up state .
