here is my new section module controller; built to control my Berthoud sprayer (7 sections; valves controlled by 12Volts on/off; no canbus on this model)
Blue button to swap Automatic/Manual mode (red switch is the emergency "stop" in case of system failure...)

....although he was asking about it earlier in the thread. I'm confused. Easily done. :rolleyes:

Indeed my actual controllers are managed through "proprietary" protocol, but I would like to extend the soft:
  • first step, to be able to communicate with the tractor canbus (to fully automate the headland turn)
  • second step, to be able to communicate with market controllers using Canbus.
So, Thanks for the link ! :)
 
Most applications that need to be integrated better would already have hardware fitted with an network output to the 11783 standard. But hardware will be readily available, its the programming or changing of the programming would be the difficult part.
Easiest standalone hardware to implement would be PLC's with 11783 data network, click
Can all be done in software no need to buy hardware or PLCs (very 80s and 90s).

Cheap tablet for the host processor, along the same lines as Stefan Richter of NX9 has done. I posted link above.

Had a look a the Fin uni link above. Looks like a bit of an abandoned research project from 2007. Macros look very basic. I think you'd best be starting off with the work Richter has done and piggybacking on that rather than reinventing the wheel.
 
Claas numbers men have probably looked at this and thought "Oh sh*ite" we can't release this, certainly not as a potentially free/very cheap IOS app.

Even if they charged over the odds for the required Claas WiFi to CAN adapter to make some revenue - it potentially could dent/kill the sales of any Claas CEBIS and Communicator terminals and the like.

Maybe I'm just a cynic and its not ready for prime time yet....

Just got an email back from the product manager for "EASY" at Claas UK. The app will be available for download from the Apple app store in March. It will be free to download and "provides free to use ISO task management".

The wireless interface (which includes the licence for ISOBUS services) will be available from dealers about the same time. They haven't set a firm price yet but it's expected to be approx £1,500

So there you have it.

in that video the system was running in "manuel mode":
the controller has a switch in order to activate/deactivate the autosteering.
when reaching the headland,
  1. I have to deactivate the autosteering,
  2. then turn manually the wheel left or right in order to go away from the current target track
  3. then reactivate the autosteering, generally this operation occurs when tractor is at 90degrees regarding tracks direction.
  4. the tractor then is able to reach alone the next target track.

In the meantime, I developed an algorithm in order to fully automate the headland turn.
in that case
  1. I had first to delimit the field boundary
  2. choose the headland width (around 20 meters)
  3. create the mastertrack (A-B or curve)
  4. track path is pre-calculated regarding turning radius versus implement width in order to optimize the turn (not too tight/wide)
  5. engage the auto steering
  6. the tractor will then follow the tracks and change from track to track autonomously when reaching the headland.
  7. as the implement is not managed by the system, I still have to do it manually(pto, lifting...)
I hope that my explanations are clear.
feel free to ask more info.

While cleaning my phone memory, I just found a video I took (bad quality on my phone, and very shaken) which shows the "Atuomatic Headland Turn".

Unfortunately I did'nt cut the vegetable on the full headland width, so it seems that the tractor has not enought space to finalize the turn within the headland.

Got to give it to you, the amount of work gone into the coding and algorithms is impressive (y)

Do you have a lot of issues with drift being on egnos?

Egnos drift when spraying at 28m a field within 1-2hours is not a problem.
Drilling (cereals) a whole day long at 3m can give some holes/overlap (I posted some pictures, see above).
In my case, I prefer to suffer (from time to time) from egnos drift than driving myself the whole day.
