ADAU1701 and fault detection
Hello,
I'm a Masters degree student and one of my possible final thesis theme is fault detection using dsp. I have a question regarding ADAU1701. Is it possible to use this device to detect faulty equipment using audio samples?
At the moment I'm thinking of using only asynchronous motor sounds to detect faults. I think it may be possible to do so by using FIR or IIR filters on faulty equipment audio sample and healthy equipment audio sample to detect changes in final data.
Before finalizing my thesis theme I'm wondering if such an idea is even possible to realize by using ADAU1701 processor and SigmaStudio software for audio signal sampling and MATLAB for final data analysis.
Thanks in advance,
Marius

Hello Marius,
I guess it depends on how difficult of a signal you are trying to measure. I know that some people have used SigmaDSPs for this purpose so it is possible. I suggest you use the ADAU1452 which has a lot more processing power. The ADAU1701 is somewhat limited but if it is a simple problem of using a notch filter to detect a wheel bearing that is going bad then the 1701 should be able to do that. Other more tricky signals will need the more advanced ADAU1452. Then if you are really looking for very in-depth analysis then look at the SHARC processors. The SAM board is probably the best deal. Here is where you can find it:
The SHARC board is more difficult to program but you can program it in C is you like. The SigmaDSP is quick and easy to get started but you are somewhat limited if you need to do custom code.

Hello Dave,
Thank you for the answer. I have a ADAU1701 board so I would like to use it if possible. It's good to know that It's possible to detect some faults and that it's a feasible idea. I'll also look into SHARC processors that you mentioned.
