In this embodiment, the maintenance time refers to the time elapsed since the last maintenance of the connection stability problem of the cathode cord; the third predetermined threshold is a time value used for judging whether the maintenance time corresponding to each repeated abnormal mark is in a reasonable range.

Specifically, when the cathode rope is maintained each time, timing is started after the connection stability of the cathode rope is maintained; if the stability maintenance of the pot is not carried out after the electrostatic dust removal device is used, timing is started when the electrostatic dust removal device is used; after the repeated abnormal marks are determined, obtaining maintenance time corresponding to each repeated abnormal mark from the terminal, comparing each maintenance time with a third preset threshold value, and judging whether each maintenance time is greater than the third preset threshold value or not; if the maintenance time is less than a third preset threshold value, judging that the cathode rope has low possibility of deviation as the reason of temperature abnormality of the anode dust collecting pipe corresponding to the repeated abnormality mark; if the maintenance time is longer than the third preset threshold value, the anode dust collecting pipe corresponding to the repeated abnormal mark is judged to have high possibility of temperature abnormality caused by cathode rope deviation, so that the repeated abnormal mark with temperature abnormality caused by cathode rope deviation is further accurately screened out.

S322: and if so, taking the cathode rope mark with the maintenance time larger than a third preset threshold value as a repeated abnormal mark.

Specifically, if it is determined that the maintenance time is greater than the third predetermined threshold, the cathode rope identifier of which the maintenance time is greater than the third predetermined threshold is used as the repeated abnormal identifier, so that the accuracy of the pulled cathode rope is improved.
