摘要
介绍了一个多通道高速数据采集系统的实现,主要讨论了该系统的硬件结构和采用DRAM实现海量缓存,提高负延时深度的方法。
Periodical sampling technology of rotating machinery vibration signal is useful for precise signal analysis.In this paper, a circuit for muti channel periodic and simultaneous sample control is introduced.Togather with micro processor and A/D circuits, high performance turbo machinery vibration data collect system can be generated,and this is the base of further data processing include analysis and diagnosis.This circuit simplified the construction of turbo machinery vibration data collect system,and can be used directly.
