Abstract

The invention relates to an equivalent parameter measuring method and device of an ultrasonic transducer and a controller. The method comprises the following steps: acquiring an initial frequency sweeping interval, and performing frequency sweeping on the ultrasonic transducer at a first step length in the initial frequency sweeping interval so as to acquire a first half-power point and a second half-power point of the ultrasonic transducer; wherein the first step length is an increasing step length; performing frequency sweeping on the ultrasonic transducer at a second step length in a target frequency sweeping interval to obtain a first feedback electrical parameter set of the ultrasonic transducer; the target frequency sweeping interval is a frequency band between the first half-power point and the second half-power point; and obtaining equivalent parameters of the ultrasonic transducer according to the first feedback electrical parameter set. By adopting the method, the time consumption for measuring the equivalent parameters of the ultrasonic transducer can be shortened, and rapid measurement is realized.

Description

technical field [0001] The present application relates to the technical field of ultrasonic transducers, in particular to a method, device and controller for measuring equivalent parameters of ultrasonic transducers.
