The specific signal value may be understood as a signal value indicating a correspondence between the network address information selection signals, and the information selection signals may be understood as signals set in advance for selecting the target object.
Specifically, the association between the reset number accumulated value and the label of the information selection signal may be established in advance, the reset number accumulated value may be compared with an accumulated threshold value, and when the reset number accumulated value is greater than or equal to the set accumulated threshold value, the information selection signal associated with the specific signal value may be used as the start information selection signal.

When the reset times accumulated value is 3, and the reset times accumulated value is equal to the accumulated threshold value, the number of the information selection signal related to the specific signal value is also 3, the corresponding starting information is the network address information, and the address information selection signal with the number of 3 is used as the starting information selection signal.
And c1, if not, taking the information selection signal associated with the reset times accumulated value as a starting information selection signal.
Specifically, the association between the reset number accumulated value and the label of the information selection signal may be established in advance, and when the reset number accumulated value is smaller than the accumulated threshold value, the information selection signal corresponding to the reset number accumulated value may be searched for according to the reset number accumulated value, and the information selection signal may be used as the start information selection signal.
Illustratively, the index of the associated information selection signal is also 1 when the reset number accumulated value is 1, the index of the associated information selection signal is also 2 when the reset number accumulated value is 2, the index of the associated information selection signal is also 3 when the reset number accumulated value is 3, and so on until the reset number accumulated value is equal to the accumulated threshold value, the index of the associated information selection signal is the specific signal value.
In a third optional embodiment of this embodiment, whether to continue sending the reset signal is determined by the start control chip according to the start monitoring signal, and the start information selection signal to be sent is automatically selected according to the reset times by counting the reset times, so that automation of the start process is achieved. Because the starting control chip is controlled by the state machine running in the memory, no erasing operation is ensured in the starting process.
