We are reading temperatures in silos (bins) mainly with grain but also
animal food or other sensitive to heat products.
It's 10-90 meter silos with 1-12 cables in each and 1-20 silos and
4-16 sensors per cable. Biggest system as per now is 20 silos, 240
cables and 2400 sensors. All connected with about 8.5km of wire.
Just changing from PIC16 to LPC2138 as "heart" of the system. Spent
some days just going thrue all data sheets and sometime you just loose
focus, as with the UART, to find all specifications and values.

Is LPC2138 UART levels OK for a 5V part?

Nice system for green houses or other "lighter" use. Our cables
are
heavy duty, taking a load of 4.5 tons each. As we are mainly in dusty
environments we also face the need to meet the ATEX (explosive safe)
regulations.
We have from a handheld instrument (Windows CE) and a probe that you
stick in to the grain to a central computer talking to distributed
cards (LPC2138 + DS2480B) via a RS-485 network. 24/7 data collection
with unlimited retension of data, alarm triggers individually per
sensor / cable, alarm for raising or over temperature, reporting...you
name it and it's in there :-)
My next step is to add embedded webserver, radio modem, bluetooth and
control panel as add-on cards to it.
Cheers

Have yuo considered wireless mesh network nodes as opposed to such long
cables? I used to work with 802.15.4 and Zigbee, and that company had a good
working solution. I could post the web page if anybody's interested...

Fredrik,
I'm very interested in sensor networks. Also something I have been
working with for many years now and also do at the moment on an open
basis in the VSCP project (http://www.vscp.org) aside of my regular
consulting work.
Very impressing data for your system. You use RS-484. Never though of
CAN instead? Nice with distributed control as it solves arbitration and
is reliable to a great extent.

CAN bus was thought of but as we needed to interface with an onther
RS-485 system it was put in the drawer again.
I do am tempted to switch to it as the main bus and in case of old
system have a RS-485 doughter card the adopt to them.
Will certenly put some time on CAN after this new card is done and
maybe change later next year if possible.
I'll have a look on the VSCP project also...
All products will be on a web site about february next year.
Cheers

Yes, we talked about it in a early stage but as I don't have any
knowledge in radio and some customers said that they dont want more
radio interferance in their plants made us leave it at that time.
The radio module I'm looking at now is for connecting the control room
with the plant instead of using up to 500 meter of cable. And if the
plant is divided up in two, three groups use radio to make it as one
to the control room.
But, that will take some study from my side. Seen some nice ready
built ones for OEM use with a UART interface to them so maybe I don't
need to learn it all myself!
Please post the web page if you can. I do like to see it!

Have yuo considered wireless mesh network nodes as opposed to such long
cables? I used to work with 802.15.4 and Zigbee, and that company had a
good
working solution. I could post the web page if anybody's interested...

I'm sure you're aware of the LinkOEM module? It implements Chris Fox's
design per his application note, in fact I believe it may incorporate his
firmware.
