Job possibility; Need a DAQ HMI

Catwell
I have a 3 sensors that output 0-10V or 4-20mA signal directly. Data is sent constantly.
I want to take that data into a Windows application and display the incoming data on a graph in real time among other options: see Design requirements below.
The software does not have to be flashy with lots of eye candy. Practicality is key. The software will end up on a Windows XP or 7 system. Although the specs a laid out, new features may be added.
 
Design requirements:
- Read DAQ data via USB
- Handle 1-10 inputs
- Real time graph on the data on set scales
- Speadsheet stored data in real time
- On screen values shown prominently
- A control interface for handling the system (On/Off, record, stop, etc..)
- I would like the data to be sent via email from the same interface
- Full graphs of all the data collected from the 3 sensors printed from within the interface
 
I already use some free software, Picologger, that can handle most of this, but I do not like the interface, it crashes, and some of the options I want are not there. I am using a ADC-24 Data Acquisition module from Pico Technologies. However, I am open to other options.
 
Let me know if you can help.

  • Hi Cabe,

     

    This sounds like the perfect task for LabVIEW (but, fair warning, I'm a huge LabVIEW fan).  As a graduate RA, one of my tasks was to redesign a monitoring and control interface for a PEM fuel cell test stand.  I used LabVIEW 2009 to do this.  My new program contained literally every function you mentioned above and then some (although the DAQ we used was not from Pico).  The post-doc I was assisting was probably most pleased with the ability of the stand to automatically email her the results of a test at the end of a cycle.  And this was the easiest part of the whole project.  (But isn't that always how it goes?)  These days I use LabVIEW for my work at Deere.  This involves a lot of CAN interface work as well as some HIL testing.

     

    Anyway, I'd be happy to assist, just for the fun of it.  You can download a free, full-featured 30-day trial of LabVIEW 2011 here.  If you'd like to see a few of my LabVIEW programs (we call them VIs, or virtual instruments), just search my blog for the tag labview (although if you'd like to go directly to some of my better GUIs, this wind tunnel control VI and this fuel cell demo VI are pretty neat).  Unfortunately I don't have any posts about the main test stand VI I mentioned, only because some of that stuff was proprietary.

    Mike,

     

    Your helps will go a long way. Glad to have you backing me up on this.

     

    Can you recommend a better DAQ? The Pico ADC24 is not pico at all, it is huge. In the enclosure it has to be the biggest component.

     

    Will talk with you soon.

    Hello Cabe,

     

    I can't resist the invitation to recommend a DAQ - look at www.hgl-dynamics.co.uk and the Dragonfly parts. Amazingly good and brilliantly designed - especially some the really cool stuff in the FPGA (which I worked on !!!). As you will guess from the picture on the website - it costs a bit more than the Pico (and is much bigger) - but you do get 8 channels, 24 bits, 200kHz.

    If you want small then it's harder:

    do you want more than one, how small would you like, USB or Ethernet, ideal spec - can I design one for you  ?

     

    (Oh dear I'm getting carried away again - I'l have a cup of tea !)
