The invention relates to an ultrasonic transducer driving method, system and device. A method for driving an ultrasonic transducer, comprising the steps of: collecting excitation current data of an ultrasonic transducer; determining the current operation of the ultrasonic transducer based on several continuously detected expected values and variance values of the excitation current data state, and then perform the corresponding follow-up operations. The ultrasonic transducer driving method provided by the present invention can judge whether the transducer is in contact with the human body based on the expected value and variance value of multiple excitation current data obtained through continuous detection, and can also eliminate the impedance change caused by the couplant, make the judgment more precise.
Description
An ultrasonic transducer driving method, storage medium, system and device technical field [0001] The present invention relates to electronic equipment, and in particular, to a method, system and device for driving an ultrasonic transducer. Background technique Ultrasound therapy utilizes the mechanical effect, thermal effect and physicochemical effect of ultrasound to make the deep tissue of the human body produce "inner". "heat generation", which makes local blood vessels dilate, blood flow is accelerated, metabolism is enhanced, muscle tone is decreased, pain is relieved, and the ductility of connective tissue is increased. Plus, and then promote the recovery of certain diseases. Ultrasound therapy equipment treats the human body, mainly through ultrasound therapy equipment The internal high-voltage pulse signal excites the ultrasonic transducer in the ultrasonic treatment head, thereby generating ultrasonic emission to achieve the purpose of treatment. of. In ...
