Compare real-time graphic to a database

[otaconlink]

Hello, I`m from Brazil and I apologize for any English mistakes I make.

I want to detect problems in a motor by analyzing vibration. I bought an accelerometer (adxl345) and an Arduino board to acquire the signals. The components haven`t arrived yet, but I want to start creating the LabVIEW application.

There are plenty of tutorials on how to analyze vibration on the internet and there are a lot of people who has done this before, but I can`t find anyone who has tried to compare a frequency domain real-time signal captured from the Accelerometer with a signal stored on a text or spreadsheet file.

What I want is to make an application that can automatically detects what is the problem on the motor, instead of comparing the graphics by myself.

Does anyone know if that is actually possible with LabVIEW? Maybe you can share some tutorial or knowledge on this.

I really appreciate any kind of help you can give. Thanks in advance.

Hi otaconlink,

Look at these links about Sound and Vibration Measurements:  

http://www.ni.com/white-paper/3575/en

http://www.ni.com/white-paper/6107/en

Keep in mind much of this work can be done without the toolkits if you don't have them, but the white papers will start steering you into the right direction.

Thanks for the links, I`m using the LabVIEW 2010 and I do have the Toolkits.

I`ll start reading those links.

If I find something that solves my issue I`ll mark your aswer as the solution.

I coundn`t find a way to compare a graph to a database in order to have a match. Does anyone know how to do that?
