title = "DESIGN OF ULTRASONIC GENERATOR INTERFACE COMMUNICATION AND ENABLE CIRCUITS",
abstract = "This paper introduces two circuit designs for the interface of the ultrasonic generator. The original communication circuit is primarily designed based on RS485 communication principles, and it has issues with erroneous communication data due to excessive noise. We add isolation design and decoupling capacitors to reduce noise. The original enable circuit is primarily designed based on opto-isolation principles, and also experiences false triggering due to excessive noise. We incorporate a Schmitt trigger, RC low-pass filter and diode protection to stabilize the enable signal. Therefore, the communication signal can be transmitted stably to the ultrasonic generator for precise control.",
