基于USB的发电机组振动和噪声故障监测系统

摘要

A new fault monitoring system which combine vibration parameter and noise parameter was developed. Data transfer and communication in the system was highlighted. By converting RS - 485 serial communication into USB, data transfer between data acquisition module and LabVIEW was implemented, and also adjust conveniently at site and improve the rate of data transfer. In a word, the system achieved the purpose of monitoring the status of generator units efficiently.%开发了一种新的汽轮发电机组故障监测系统,即集合振动参数和噪声参数的汽轮发电机组故障监测系统,详细介绍了系统的通信和数据传输问题,通过将RS-485串口通信转换成USB通信方式,实现了下位机数据采集模块与上位机LabVIEW监测界面的数据传输,方便了现场调试,提高了传输速率,达到了有效监测发电机组运行状态的目的.
