A set of induction motors are tested in both, healthy and faulty conditions (unbalanced rotor, damaged bearings and broken rotor bars) to analyze vibration and acoustic signals recorded with a smartphone. Then, recorded data is analyzed to identify healthy and faulty emissions signatures. A total of roughly 85 minutes of acoustic emissions and around 125 minutes of vibration data are recorded along all different operating conditions. Results show that it is possible to estimate machine rotational speed and detect faults with the smartphone recordings. Acoustic emissions’ faulty signature is located between 4 KHz – 8 KHz in the form of high magnitude frequency clusters and speed can be estimated using mechanical rotational frequency harmonics present between 100 Hz- 1 KHz. Similarly Vibration faulty signature is located along the frequency spectrum in the form of high magnitude peaks and rotational speed can be estimated by using peak vibration frequency. Finally a fully functional Android application was develop based on test results to automatically detect motor speed and health status. Validation testing showed 90% accuracy in fault detection.
It requires 2 users connected to the same wireless network, and than, the sender can send a file simply by inserting receiver IP address, or selecting the receiver user name from the list of connected users, after that, files will be trasferred as soon as possible.
Received file are stored in the specified folder on the storage memory.
It's also possible to send files selected from an external file browser, like a Photo Gallery, via "Send"/"Share" action.
