| Abstract: | Frequency information plays an important role in vibration monitoring and fault diagnosis of rotating machinery. Multiple channels' data sampling and maintaining should be realized simultaneously in order to achieve correct frequency information. This article deals with a method of multiple channels' parallel data acquisition simultaneously, it provides hardware connection circuit and discusses the effect of gate control signal on the data acquisition frequency range improvement basing on two different software structures and programming ideas. |
