when T is 0, the comparison value of the voltage data is smaller than a first preset value, and the comparison value of the current data is smaller than a second preset value, and a reminding signal is not output for reminding;
when T is equal to-1, the comparison value of the voltage data is smaller than a first preset value, and the comparison value of the current data is larger than a second preset value, and then a current data reminding signal is output for reminding;
when T is 1, the comparison value of the voltage data is larger than a first preset value, and the comparison value of the current data is smaller than a second preset value, a voltage data reminding signal is output for reminding;
when T is 2, the comparison value of the voltage data is larger than the first preset value, and the comparison value of the current data is larger than the second preset value, and then the current data reminding signal and the voltage data reminding signal are output at the same time for reminding.
