7. The ultrasonic voltage matching method of claim 6, wherein controlling the voltage input to the ultrasonic array element to be less than or equal to the first preset voltage value comprises:
when the cut-off protection instruction icon is triggered, controlling to cut off a pulse voltage signal which is input in advance, so that the voltage of the input ultrasonic array element is 0V;
when the voltage limiting protection instruction icon is triggered, limiting the voltage of the pulse voltage signal input into the ultrasonic array element, so that the voltage input into the ultrasonic array element is smaller than or equal to the first preset voltage value.
8. The ultrasonic voltage matching method of claim 1, wherein when the peak voltage of the input ultrasonic array element is equal to a first preset voltage value,
judging whether the voltage input into the ultrasonic array element is subjected to voltage limiting treatment;
if the input voltage is subjected to voltage limiting processing, an abnormal prompt message is sent to a user.
9. An ultrasonic voltage matching system, comprising:
the interface detection module (7) is used for detecting whether the ultrasonic host interface has a selectable operation instruction icon;
the voltage acquisition module (1) is used for acquiring pulse voltage signals of pre-input ultrasonic array elements in real time;
the peak value analysis module (2) is used for acquiring the peak value voltage of the pulse voltage signal;
the judging module (3) is used for judging whether the peak voltage is larger than a first preset voltage value or not;
the instruction icon generating module (4) is used for generating a corresponding protection instruction icon according to a judgment result of the judging module (3), and if the peak voltage is larger than the first preset voltage value, the instruction icon generating module (4) generates a protection instruction icon;
the icon detection module (8) is used for detecting whether the protection instruction icon is triggered in real time;
and the signal processing module (5) is used for controlling the voltage input into the ultrasonic array element to be less than or equal to the first preset voltage value according to the detection result of the icon detection module (8).
