AgOpenGPS How to build Section Control

[davidroberts30]

dont forget to check for bad earths

Well i finally got round to putting up my section control build on a 12 row beet drill. The seed cells were electric driven so i got 2 lots of 8 relay modules and hooked up to each motor

The arduino nano was only able to operate 10 switches from standard so had to alter some coding to find 2 more pins that switched 5v

Had to buy a few bits and bob but probably cost £50 tops

Managed to get it all connected up and ran it in simulator mode to test it was all functioning

Had to assign the pins on the nano to each section but these wasn't in logical order so took some working out

Was a bit trial and error in the 1st field altering time delays but i dont think its too bad. Was aiming for a seed to be dropped within 50cm of the outter headland drill row and i got it to drop a seed at 40cm

Few videos of agopengps controlling the 12 row beet drill.

Can also put tramlines in and do half width shut off to get the 1st tramline against a straight hedge

All in all im pretty happy with how this has turned out, will see more when it starts to grow!
Many thanks for all the help along the way

That's brilliant!

I think the hotchpotch of pin numbers is a legacy from the early days when a single Nano was doing autosteer and some machine control, hence the first few pins and any logical order were taken up by the pins doing other primary tasks.

Hope it all comes up as you hope!

As you know i had a few false starts along the way but we got there in the end.
My biggest pain was getting agopengps to run exactly on the tractor gps same path for coverage. If i altered anything on the tractor gps i also had to alter agopengps aswell each time or the coverage would be wrong. It was the 1st proper day out with the claas gps so took some time. I think in hindsight if id have put the agopengps antenna on the drill it mightve been alot easier
Ive actually got agopengps running 2cm less than the tractor to try and limit any mishaps of the outter sections turning off.
Im still anazed how accurate agopengps can run with the big brands for accuracy. I plottted the ab line on both systems at the same time.

Were both AgOpen and the OEM steering using the same Co-ordinates for the AB line? You can manually input them so they're exact. Pressing A and B on the screen can still give a fair error.

And using the same RTK signal?

No i just pressed a and b on both systems while i was stationary.
Claas is running on there own rtk and agopengps on rtk2go. I dont normally run guidance lines on the agopengps as i just use it for coverage but just done it to see how far off it might be.

well done

dont forget pics as its growing!!

Might have to hoe a few seeds out 1st if its not worthy of a photo

For automatically making the tramlines come on on an accord seed drill, what is my best option? Just wire them up as section control? Or is there another way?

Yes wire up as section control then choose Tramline in the pin selection:

Teaser time....

Canbus section control?
