[Measurement System Case] Compressor Abnormal Noise Judgment
Detecting abnormal noises from compressors equipped in home appliances such as refrigerators!
One of the quality requirements for household refrigerator compressors is "quietness." The abnormal noise and vibration inspection conducted during the production line is not easily detectable with conventional FFT judgment devices due to surrounding noise and vibrations from manufacturing equipment. By using PJ-FFT (Point Joint FFT), which can determine instantaneous signal changes with a very short FFT window of a few milliseconds, automatic judgment becomes possible. There is also a function (optional) that not only determines OK/NG but also displays the cause of NG. This allows for logical derivation of detected NG data based on the frequency bands and combinations of counts when an NG judgment is made, enabling the specific display of the cause if it has already been identified. Our company can provide judgment methods such as area judgment, area accumulation, multiple level settings + area judgment, allowing customers to construct complex judgment logic according to actual situations and seek more accurate judgment results. *For more details, please refer to the PDF materials or feel free to contact us.
