Ultrasonic transducer driving method, system and device

Abstract

The invention relates to an ultrasonic transducer driving method, system and device. The ultrasonic transducer driving method comprises the following steps of acquiring excitation current data of an ultrasonic transducer; and determining the current working state of the ultrasonic transducer based on expected values and variance values of the plurality of continuously detected excitation current data, and further executing corresponding subsequent operations. According to the ultrasonic transducer driving method provided by the invention, whether the transducer is in contact with a human body or not can be judged based on the expected values and variance values of the plurality of excitation current data obtained by continuous detection, and meanwhile, impedance change caused by a coupling agent can be eliminated, so that the judgment is more accurate.

Description

technical field [0001] The invention relates to electronic equipment, in particular to an ultrasonic transducer driving method, system and device. Background technique [0002] Ultrasound therapy uses the mechanical effect, thermal effect and physical and chemical effect of ultrasound to generate "endogenous heat" in the deep tissue of the human body, dilate local blood vessels, accelerate blood flow, enhance metabolism, reduce muscle tension, relieve pain, and extend connective tissue. Sexuality increases, thereby promoting the recovery of certain diseases. Ultrasonic therapy equipment treats the human body, mainly through the high-voltage pulse signal inside the ultrasonic therapy equipment to excite the ultrasonic transducer in the ultrasonic therapy head, thereby generating ultrasonic waves to achieve the purpose of treatment. [0003] In the actual use process, when the ultrasonic transducer is not in contact with the human body, its ultrasonic energy cannot be exporte...

AI Technical Summary

Problems solved by technology

The technical solution disclosed in this document uses the method of detecting light waves to detect temperature, but it still cannot accurately identify whether the ultrasonic transducer is accurately in contact with the human body

[0006] Therefore, there are deficiencies in the existing detection technology of the working state of the ultrasonic transducer, which needs to be improved and improved.
