BX-24 + GPS + GPRS for fleet-tracking

Started by harris_cohen September 21, 2005
Hi,

I need to design a rugged, industrial-grade fleet-tracking system
using BX-24 and GPS + GPRS modules to periodically send SMS text
messages with GPS location data for each truck back to a server.

Can anyone recommend rugged GPS and GPRS modules (or an off-the shelf
product) for this purpose?

Thanks,
Harris Cohen


Just my 2 cents worth but how about doing some of the work you are paid to do and then ask questions!

Harris, for starters, use a BX-24P which is better suited to that
environment. Expanded temperature range is the major feature. It also
has a wider supply voltage range and is a little faster. Sorry but I
can not help with the other.

Hello!

You may want to have a look at the things available from Sparkfun
Electronics (www.sparkfun.com):
- GSM cellular module
- GPS module

These things might also be interesting to all you guys out there that do
work with wireless telemetry or remote monitoring. The italian-made
Telit GSM-module offers an impressive wealth of functionality.

But then, of course, and particularly for vehicle tracking, there are
also ready-made solutions on the market (at much higher prices..).

Even though I basically agree with Mark Newell's follow-up post to the
initial question, at times all it takes is a piece of information to get
started in a certain direction and a forum like this is exactly that, a
source of information among peers, isn't it?

For the record: I am not affiliated with Sparkfun nor Telit.

Greetings from Mexico.

You have left to many question that you have to look at.
You need to know the distance that you are using this.
Small area - mostly just a Rf Transciever
City Area - then the RF transceivers and repeaters
Nation wide - Satellite.
I designed one of these for a RC Helicopter Search and Rescue for
about 7 Miles out using a GPS with twin cameras. 1 camera just to fly
the unit and using packet radio from the audio of the video
transmitter to insert the gps data. These were used with just the
rubber ducky antenna's.
However you will have to program all the Truck ID's into each
processor to know what truck is where.
Here is a site to get you started.

There are several of these sites around however I started out using a
Radio called Coyote Datacom. There radios would be fast enough for
what you are doing but they were not fast enough for my servos.The
Basicx 24 will work just fine for this even in cold weather.

Ken,

The GPRS he listed is a cellular data network. So,he has the
communications all thought out, I think.

It strikes me that the "phone home" approach will work anywhere
there is cell service, and if there is no cell service, there is not
likely to be any repeater service unless it is close to home base.

So, All you need is a GPS module to send ascii
location/direction/speed/time text to a controller, and then the
controller periodically uses a cell phone module to call home with
the data.

It can be simple point data, or it can be a log of all the waypoints
over time.

Probably better to have much more capacity to store waypoints than
is usually needed so that data is not lost if cellular signal is
lost in a dead zone.

Both the GPS and GPRS devices are available as neat modules that are
reasonable to interface.

I think I saw all that stuff in Digikey. As someone else said,
sparkfun has good stuff, but not a huge variety of stuff.

I just checked. Digikey does not have all the stuff, but Sparkfun
does have GPS and GSM modules that, while not cheap, will interface
easily.

-Tony


I have also found 2 GPS/GPRS or GPS/GSM systems at both
http://www.laipac.com and http://www.falcomusa.com which seem useful.

Does anyone have experience with these 2 company's products?

Thanks,
Harris
