摘要
介绍了一种新型的 8路水轮发电机振动摆度信号的采集与处理系统。该系统主要由 A/D转换器、C5 4 x系列数字信号处理器 (DSP)及工业控制计算机组成。模拟信号经过采样后 ,由 DSP完成数字滤波、FFT谱分析等工作 ,工业控制计算机作为主机 ,负责管理整个系统的正常运行。
A new type of eight-channel hydropower generator vibration signal acquisition and processing system is introduced. The system is composed of a DSP chip of C54x series with A/D conversion and an industrial controlling personal computer. After sampling of analog signals through A/D conversion, the adaptive filter and FFT spectrum analysis are achieved by the DSP chip. The computer controls the work of DSP and takes charge of the operation of the whole system.
