the working voltages of the two units are adjusted to the standard voltage, so that the two units operate normally, the power parameters generated by the units are determined, the power parameters generated by the front-end abnormal linkage unit are calibrated to be G1, and the power parameters generated by the abnormal unit are calibrated to be G2;
when the difference value between the power parameter generated by the corresponding unit and the power parameter at the previous time point exceeds Y4, recording fluctuation once, wherein Y4 is a preset value, when fluctuation occurs, starting to record, if the fluctuation times continuously exceed 5 times within the subsequent 10min, representing the unit as an abnormal unit, marking, displaying through a display end, and allowing outside personnel to check.
