Condition monitoring of cutting processes
Detection of incorrect activation of valves
In a dust extraction system, the incorrect switching of valves is to be detected. Due to the strong room acoustics and the reverberation under the valve cover, it is not possible to locate the running time.
Requirements
- Detection of incorrect activation of 280 valves
- Faulty activation of a valve should be detected by localizing the cleaning noise
- Measurement with 16 microphones on the system
Solution
- Improved machine learning approach enables significant reduction in hardware costs
- From over 70 statistical features per cleaning sound and microphone, the five most meaningful are selected for analysis.
