Self-cleaning HF filling connector and control system thereof

The invention discloses a self-cleaning HF (hydrogen fluoride) filling connector and a control system of the self-cleaning HF filling connector, and the self-cleaning HF filling connector is applied to the field of filling. An outer cleaning ring and an inner cleaning ring which are driven by a mechanical arm are additionally arranged on the basis of an existing filling connector to conduct self-cleaning on the pipeline wall of the connector; then the air bag is inflated to be expanded, then the air bag enables the cleaning scraping plate to be attached to the inner wall and the outer wall of the connector, and the cleaning scraping plate rotates to achieve effective cleaning of the pipeline wall; in addition, hydrogen fluoride is effectively prevented from leaking out through the plugging effect of the outer cleaning ring and the inner cleaning ring when filling is not carried out, the safety of the filling operation is improved to a certain degree, hydrogen fluoride is detected in real time through the hydr
