Title:
OPERATION CONFIRMATION DEVICE AND OPERATION CONFIRMATION METHOD OF ULTRASONIC VIBRATOR AND ULTRASONIC VIBRATOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018084555
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an operation confirmation device that (1) makes it easy to confirm operation of an ultrasonic vibrator and an ultrasonic vibrator control device in air without restriction such as a work environment and a ban on access, (2) confirms transmission performance of the ultrasonic vibrator and the ultrasonic vibrator control device in the operation confirmation in air, and (3) does not cause deterioration or damage to the ultrasonic vibrator in the operation confirmation in air.SOLUTION: An operation confirmation device includes: a transmission signal generation unit 21 that generates a transmission signal that is for generating an ultrasonic wave radiated to air from the ultrasonic vibrator 1 and transmitted from the operation confirmation device itself 2 to the ultrasonic vibrator 1 so that power of an ultrasonic wave radiated from the ultrasonic vibrator 1 to air is lower than power at a detection time of a target in water; and a transmission parameter output unit 24 for outputting a transmission frequency value and/or power value regarding a transmission section of an ultrasonic wave from the ultrasonic vibrator 1 among reception signals received at the ultrasonic vibrator 1.SELECTED DRAWING: Figure 2
