More Information
Summary:The invention relates to a radar speed measurement machine carbon brush abrasion identification method based on time domain feature value analysis. The method comprises the first step of sensor installation, the second step of signal obtaining, the third step of amplitude modulation and judgment, the fourth step of mean square root calculation, the fifth step of mean square root comparison, the sixth step of kurtosis calculation and the seventh step of kurtosis comparison. By means of the radar speed measurement machine carbon brush abrasion identification method based on time domain feature value analysis, the carbon brush abrasion conditions of a radar speed measurement machine can be monitored accurately in real time on the condition of not dismantling the machine.
