A novel signals splitting method for intermittent sampling in deficient period

To analyze the real-time status of the pumping unit by virtue of its motor electrical information, accurate data analysis was generally required, coupled with a higher sampling frequency. This leads to a higher demand of the hardware and software configuration, especially for on-line analysis. Continuous high-speed sampling brings a large number of data-processing tasks, which makes the computer¿s resources lacked. By selecting appropriate schemes of intermittent high-speed data acquisition with an eye to the actual signal characteristics, the awkward situation maybe changed. Considering the problem of data-processing during data acquisition, one fitting-first HHT signals splitting method is proposed. It can provide a more feasible idea to improve the analysis precision of the motor electrical information.
