Save electricity.
Unlike the prior art, this case is in caller state or called state and the caller state or called state
It is switched on ultrasonic sensor when corresponding call access failure, first in order to obtain the estimated transmitting of ultrasonic sensor is preset
Tranmitting frequency, rather than only just opened in talking state.
Step S30 obtains the first default tranmitting frequency of the ultrasonic sensor.
Step S40, the first default tranmitting frequency and the first interference signal frequency.
In the present embodiment, after opening ultrasonic sensor, the first default transmitting of the ultrasonic sensor is obtained
Frequency.First default tranmitting frequency is preset frequency, and if predeterminated frequency is in A frequency, i.e., the first default tranmitting frequency is A frequency
Rate compares A frequency and the first interference signal frequency, when ultrasonic sensor, which is apprised of, needs to emit A frequency to sentence
Whether disconnected A frequency will receive the first interference signal frequency interferences.
Step S50, if the first difference between the first default tranmitting frequency and the first interference signal frequency is less than
One preset value then adjusts the first default tranmitting frequency based on first difference.
In the present embodiment, compares the first default tranmitting frequency and the first interference signal frequency, obtain between the two first
Difference then illustrates the first default tranmitting frequency and the first interference signal Frequency Synchronization when the first difference is less than the first preset value,
