Title:
METHOD AND APPARATUS FOR IDENTIFYING ERROR SIGNAL, STORAGE MEDIUM, AND PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2022/134693
Kind Code:
A1
Abstract:
A method and apparatus (300) for identifying an error signal, a storage medium, and a processor (320), belonging to the field of electric appliances. The method for identifying an error signal comprises: acquiring a reflection signal received by an ultrasonic detector (310) (S102); determining that the amplitude of the peak in the reflection signal is greater than a preset threshold (S104); determining a ratio relationship between the height of the ultrasonic detector (310) relative to the object being measured and the amplitude (S106); determining that the ratio relationship does not satisfy a preset ratio relationship (S108); and identifying the reflection signal as an error signal (S110). The method for identifying an error signal can reduce the problem of high cost.
