Need help designing a "one-off" DAQ system
Need help designing a "one-off" DAQ system
(OP)
Hi,
I'm not sure if I'm in the correct forum, if not please direct me in the right direction.
For the past few years I have been pondering the idea of building my own DAQ system. This is not because I feel that existing DAQ systems are inferior, I simply have not seen anything that will do the things I want.
Generaly, I need to measure aproximately 50 seperate things, e.g. rotational speeds, various tempurture points, atmosphircal conditions. From what little I know I have determined that 45 digital and 5 analog channels will be needed. I would like record at least one hour worth of data from all of the measuring channels. Of course, I would like to down the data via RS-232 or something of the same idea. Additionaly, I will eventually set the system to transfure the on-board data using "Burst Telemetry"
Also, while driving the data will need to be sent to a small CRT dash unit for visual reference and warning perameter settings. I thought I would use LabView products.
The application is for a high speed gear-box 2-stroke engine go-kart.
If there is anyone who direct or guid me through this would be greatly apprecive.
Please except my graditute for just taking the time to reed and response.
Thanks.

The important thing is how fast you want to read the data. Send me details on dixie.m@email.si.

We built an Iotech system for hydraulic testing, isolating noise from the portable system was a bit of a challenge. Weight may become an issue for a single system, so several small units may be a better choice. Do a search for data collection at http://www.globalspec.com

Do you want to store it and analyze later or at real time?

If I understand your question correctly I wish to record/log about an hours worth per session.
Regarding your question about storing data to analysis is coreect.
Only about 10^ to 15% of the channels analog form.
