| 摘 要： | 发电机组长期运行在高速、高载荷状态下经常会出现一些意外的、突发性的故障.为了能够完整、准确地捕获到这些故障的前兆信号或者故障发生时的特征信号,本文设计研制了一套基于CPLD和双SRAM的发电机组状态监测系统数据采集卡用以对发电机组进行状态监测.该数据采集卡采用双SRAM交替存储机制,实现了对信号任意长度的连续采样,确保不会造成瞬态数据丢失,提高了监测的可靠性.另外,数据采集卡采用了两片四通道同步采样芯片AD7865,实现了八通道信号的同步采样,可以方便地通过键相信号获取各个测点间的相位关系,为信号分析提供了便利. |

| Abstract: | The generator unit continuously worked under the high speed and high load condition for long time,so generated some abnormality,unexpected faults unavoidably.In order to capture the signal or the precursor signal of the faults completely and accurately,this paper designed a data acquisition card for generator unit monitoring system based on CPLD and double SRAM for monitoring its running-state.The card which used the alternative storage method realized consecutively and random length sampled,enhanced monito... |
