Abstract:An online multi-channel vibration signal data acquisition system based on FIFO for rotating machine is introduced.The selection of hardware,the design and realization of the system are described.The characteristic of data acquisition is analyzed.The digital filter algorithm is used to filter signal interference,and the strategy to judge the running condition and incident review of unit is given.Software trap is to improve the stability of the system,and the accuracy of the system is checked up through signal measure.At present,the system has been successfully running at a power plant for the vibration signal data acquisition.
Keywords:rotating machine  vibration  data acquisition  FIFO  online  multi-channel
