Summary:The invention aims to provide the frequency measurement method capable of automatically adapting to the measured signal, which can automatically adapt to a proper frequency measurement method according to the frequency of the signal to be measured. The method comprises the following steps: 1, selecting a direct frequency measurement method or a multi-cycle synchronous frequency measurement method to carry out frequency calculation on a signal to be measured input by a system; 2, if an event I occurs, namely after the direct frequency measurement method is selected, the frequency of the input signal to be measured is low, adjusting to use the multi-cycle synchronous frequency measurement method to carry out frequency calculation on the signal to be measured; 3, if an event II occurs, namely after the multi-cycle synchronous frequency measurement method is selected, the frequency of the input signal to be measured is high, adjusting to use the direct frequency measurement method to carry out frequency calculati
