Machine Fault diagnostic device using vibration and noise signal and big data based smart sensor system using signals therefrom

摘要

Vibration sensor 100 for detecting the vibration of the machine; Acoustic sensor 200 for detecting the noise of the machine; a time and frequency data forming unit 400 for forming time domain data 410 and frequency domain data 420 from the signals of the vibration sensor 100 and the acoustic sensor 200, respectively; a code value calculation unit 500 for calculating a vibration code value and a noise code value from the time domain data 410 and the frequency domain data 420, respectively; If there are stored vibration standards and noise standards, they are used. However, if the user sets the vibration standards and noise standards in order to measure and manage vibrations at any location on the machine, it is possible to measure and , a reference setting unit 800 for calculating the average value and standard deviation of the measured vibration signal and the noise signal, and performing a function of setting the vibration standard and the noise standard in each operating condition; Defect pattern setting unit 700 in which the defect pattern data of the machine is stored; Based on the defect pattern data of the machine read out from the defect pattern setting unit 700, the vibration standard and the noise standard of the reference setting unit 800 are combined with the vibration code value and the noise code value of the code value calculation unit 500, respectively. a comparison unit 600 that compares; Defect notification unit 900 for expressing the comparison result to the outside based on the comparison result of the comparison unit 600; a data storage unit 1000 for storing time-domain data 410 and frequency-domain data 420 of the vibration sensor 100 and the acoustic sensor 200 before and after the defect when it is determined from the comparison resu and a communication unit 1100 that transmits data stored in the data storage unit 1000 to the external device 1200 and receives a control command from the external device 1200; Machine using vibration and noise signals comprising: A fault diagnosis device is provided.
