I am a bit new on doing high-speed vibration analysis...I see a ton of info on the software programming aspect of things, though my main concern right now is getting the hardware setup correct 1st.
Right now my data-acquisition test platform consists of the following:1) A main desktop or laptop PC with a LabVIEWsoftware platform that integrates multiple device inputs into a live read-out of test-cell data-acquisition & control, as well as report analysis during and after the test. The multiple device inputs to this desktop/laptop are the following:
1) A dedicated control & daq semi-PLC device that has 2 data output options: a) USB ... 1 averaged data sample per second...this is for read purposes only, & b) CAN input/output... 10 samples per second data outpu, and allows for a control input from the desktop/laptop via a NI-8473 CAN to USB converter.
2) NI DAQ hardware inputs via MAX configuration.
My main concern is I do not want to create a bottleneck for the vibration DAQ input data. If I am looking to sample up to 5,000 samples per second max and down to 200 samples per second minimum for vibration analysis, would I be able to pull this much data in per second in using the NI-9233 module through the USB configuration? Say I have more than a few USB devices hooked up to the Desktop/laptop PC (such as other USB DAQ input/output modules) will these limit the speed input of the NI-9233 module?
My next concern is how to configure my present VI during run-time while taking all DAQ inputs (some at 1 sample per second, others at 10 samples per second).... when I begin taking up to a 5khz sampling rate for vibration diagnostics, do I just average out the other ZEROs that will be read from the other devices? And I will then most likely to need to add another time controlled loop to allow only a 4 times/per second output to the external control device so as not to time-out that device.
What would be the most efficicent cost-wise setup for the 9233 module that I could use satisfactorily? USB, PXI, CRIO?
Also, is the Sound & Vibration Analysis toolkit worth getting? I didn't check yet but does it have a cost per deployment to each executable?
Thanks.
