Realization of the motor data acquisition and analyzation system based on the producer/consumer model of LabVIEW

To solve the problems of motor's data acquisition system's low automation level, too less data channel, limited apply areas. This paper introduced a kind of motor's data acquisition and analyzation system which were developed based on producer/consumer model and LabVIEW program. This system can fulfil the tasks of multi-channel data acquisition, data analyzation and display, data saving and loading. By setting two different data acquiring frequencies, that's 2kHz and 20kHz, to acquire the same signal that produced by the signal generator and analyzing the data that were acquired. According to the analysis and data fitting results the benefits and short comes was concluded. These tests suggested that the signal can be represented by this two kind of data acquiring frequency and the standard error that the 2kHz had is bigger than that of 20kHz had. So, the test's result proved that this system works well and easy to realize.
