The Electrostatic Potential Dynamic Detection System Based on LABVIEW

The electrostatic potential dynamic detection system was designed based on LABVIEW virtual instrument technology and applied to an actual electrostatic project for the analysis of electrostatic hazards by simulating working condition of dangerous cargo and real-time monitoring of the electrostatic potential. The monopolar factor tests were carried out and measuring results for variable relative humidity, friction times and separation speed are plotted in curves. The experiment data was analyzed with the non-linear regression analysis method and the Origin software and the regression model and Matlab simulant curves between the above factors and electrostatic potential were obtained. An analysis of the test results reveals a negative correlation between electrostatic potential and relative humidity and a positive correlation between electrostatic potential and friction times and separation speed.
