When the vibration frequency of the new energy automobile charging pile exceeds the second threshold, the system preliminarily judges that potential safety hazards exist in equipment, and further performs secondary verification by combining the charging delay time length. The dual-criterion mechanism effectively avoids misjudgment of single parameters, and can improve the accuracy of fault identification. When the system confirms that the safety of the equipment is insufficient, the vibration exceeds the limit and the charging delay exceeds the threshold value, the control unit judges to re-determine the charging voltage, and the equipment generates certain loss due to long-term operation of the equipment, so that the charging pile of the new energy automobile cannot meet the charging requirement of the new energy automobile, the stability of the output voltage is improved by increasing the charging voltage, and the improvement of the operation efficiency and durability of the charging pile of the new energy automobile is further realized.
In particular, the control unit acquires the device noise intensity after completing the re-determination of the charging voltage,
And if the noise intensity of the equipment is larger than a preset noise intensity threshold value, the control unit judges that the running stability of the equipment is lower than an allowable range.
In particular, the control unit re-determines the operating frequency of the self-cleaning assembly under conditions where the operating stability of the device is below the allowable range.
In particular, the invention is provided with a device noise intensity Z, and the preset noise intensity thresholds Z0, Z0 may be set according to several test or production requirements.
In the specific implementation process, the increase of the operating frequency of the self-cleaning assembly is determined according to the product of the current operating frequency and the frequency parameter;
The frequency parameter is determined by the sum of the difference between the device noise intensity and the predetermined noise intensity threshold plus one of the ratios of the device noise intensity.
After the new energy automobile charging pile control unit completes the re-determination of the charging voltage, the new energy automobile charging pile control unit further acquires the equipment noise intensity data to form a voltage-noise double-dimensional safety evaluation system. When the noise intensity exceeds a preset threshold, the system judges that the mechanical or electrical stability of the equipment is reduced, and after the voltage is regulated, the electrostatic adsorption capacity generated by the equipment is possibly increased, so that the abrasion declared to be increased due to the increase of dust is also increased, and the control unit automatically adjusts the running frequency of the self-cleaning assembly through monitoring the noise. The high-efficiency operation of the equipment in a longer time and a lower failure rate can be effectively ensured. The running efficiency and durability of the new energy automobile charging pile are further improved.
