Hi all..

Nice seeing u all here. Thanks for a wonderful forum. Myself saikiran.
I am in need of quick solution to our project.
we r doing condition monitoring of compressor. currently we r using a microphone sensor and a microcontroller based data acquisition system for monitoring. this is online data acquisition system(note for dear amolshah) and this kit is connected to computer where we use the acquired data to do the processing, selection and classification steps using matlab codes in the computer.
the problem is, we want to develop a complete device which can do online monitoring and data processing. we r done with data acquisition kit. now we have to develop a data processing kit.
Can anyone of crazy engineers can suggest me. how to go forward.

You are doing condition monitoring of a compressor by using a microphone sensor and a m'controller based data acq. You also said this is an online system. Now you would like to have the complete system without the PC? is that correct? Like a complete device that connects only to the compressor and does the analysis?

Please provide some more details on your requirements. For example:

What are the exact analysis you are conduction?
What signal output is being given to the compressor?
Are you sending all these signals to a base station for further analysis?

Dear sir.. thank you... you are right. it should be a complete device that connects only to compressor and does the analysis and should display the status of the compressor whether healthy or faulty.
We are doing acoustic and vibration analysis of compressor.
it,s like predictive maintenance. currently we are acquiring the data using microphone and accelerometer sensors. we then process the data and do the analysis- using matlab codes in computer.

What is the scope of your analysis? I personally would recommend a micro controller such as the PIC family from Microchip or Atmel. All these controllers are written in C code and can easily connected to an LCD display or LED's to display the status of the compressor.

Yes like @everett has said you would use a microcontroller from PIC or Atmel and connect the microphone to it's Analog to Digital converter pin and the Accelerometer to a digital input. Then analyse the data inside the microcontroller. After analysis you can output the data there, if your values are "off, or not correct" then it will shut down the machine.

Otherwise connect a wireless module to your microcontroller and connect it online. But yes, analysis can be done inside the microcontroller. It might take you time to convert your MATLAB formulas (algorith) to C but it is possible.

Post some of your MATLAB calculation algorithm here so we have an idea as to what you are planning to implement.
