1 Agricultural mechanization: present meets future! November 2017 Hannover, Germany ISOBUS for Trailed Sprayers Implementation and Experience Willy Peeters

2 Content Introduction History Development, initial challenges Development, implementation challenges Plugfest and certification Current status Outlook in the future Summary Hannover, November 12-13, 2017

3 Introduction ISOBUS development start in 2005 Generic solution Multi brand market Differentiation Green-to-Green 125 competitors in the region

4 History Founded in 1947, Machine Fabriek Gebr. Douven BV. Large, diverse portfolio Orchard sprayers Mounted sprayers Trailed sprayers High pressure cleaners Pumps

5 History 1928 Theike Douven starts contracting and crop protection in Horst (Netherlands) 1947 Machine Fabriek Douven officially founded Deere & Company s signed a agreement to take over Des Moines Ordnance Plant from War Assets Administration 1997 Deere & Company invests in European factory for sprayers 2000 Deere & Company produces first JD designed sprayer in European factory for sprayers 2012 Deere & Company 175 years, with 65 years of experience in manufacturing high quality crop sprayers

6 History Acquired by John Deere November 1997 Small team Industry components used Off-shelf controls First John Deere developed trailed sprayer introduced in 2000, 800-serie New electronics, Greenstar 4 system and traditional Generic John Deere

7 History Decision to go for full ISOBUS Virtual terminal TaskController Green-on-Green on top of ISOBUS

8 Development, initial challenges No specifications No ownership of the software Development start with a 4 page document Rate control (base for a sprayer) Hydraulic control (boom control) TwinFluid (air assist nozzles) Limited experience within John Deere with implements Knowledge and expertise on self-propelled equipment in the US Proprietary protocol External partner selected Working for the Baler group (Arc le Gray, FR) Working for tractors (Mannheim, GER)

9 Development, initial challenges Hardware selection Re-use existing hardware More outputs needed than available (need 80) Additional hardware with only outputs, max 6

10 Development, initial challenges Software, main operating system John Deere Operating System (JDOS) Experience at partner Joined efforts/experience from working for Balers Application software Detail specification not available No software experts in Horst Application experts on machine operation and usage in Horst Spec development on the go

11 Development, implementation challenges Software, main operating system (JDOS) Scaling for the User Interface Development for 480x480 but required to support also others eg 272x272 Mapping of proprietary colors Limited TaskController support for implements

12 Development, implementation challenges User Interface (UI) John Deere Tool used Creation of the Object Pool Ensure alignment with US sprayers Many sprayer variants Complex handling of the UI Ensure compliance with the standard No VT+ features Deere VT is friendly for Deere equipment

13 Development, implementation challenges Taskcontroller Section Control and Documentation Sprayer first implement to use JDOS and TaskController Many hours of testing Close cooperation with JDOS development group, Intelligent Solution group Hardware limitation found TaskController commands every 20 msec of faster Used ball valves need 750 msec Mechanical/electrical issues

14 Development, implementation challenges Languages Many languages required, 14 start, today 22 Non Latin languages Avoid text but not always possible Memory limitations on hardware Load languages to the system ISOBUS file server not ready Deere version implemented Deere to Deere only Issue with non-deere equipment Integration into Deere Service Advisor Allows text update without software change Issues with multiple displays on tractors

15 Plugfest and Certification Target to be (DLG/AEF) certified Best insurance multi brand equipment work together as intended No 100% guarantee!! 2007 DLG certification achieved First John Deere implement Every software change requires re-certification

16 Plugfest and Certification Plugfest for validation Multi brand equipment connecting together Engineering driven event Strong drive to solve issues together

17 Current status Architecture change New hardware Software re-use Languages fixed installed

18 Current status AEF certified in 2015 First John Deere implement UT1.0 UT1.0 / TC-BAS / TC-SC in 2017 Currently working on ISOBUS AUX-N Operating device per ISOBUS AUX-N standard Challenge: sprayer needs much more functions then devices make available

19 Current status Challenges for future certification No legacy components allowed after 1 st Jan 2018 Ground isolation challenge Non-ISOBUS sprayers also use ISOBUS communication Allow section control Not using ISOBUS connector (cost) Power limitations Allows display strategy VT only Section Control All options

20 Outlook to the future Diag GPS TC Server Sensor IBBC Aux VT AF IBBC Lighting Termination Engine Tractor ECU Tractor Bus Implement Bus SCVs Hitch Transmission Drawbar Implement ECU Pump Implement Sub-Net Injection

21 Outlook to the future Limits due to bus speed Need for high speed ISOBUS Max baudrate 250 bps today Support for camera systems Individual nozzle control Variable rate per nozzle Direct Injection Sensors on the sprayer New hardware required in the future with new operating system ISOBUS implementation in new Operating System New ISOBUS applications like TIA/TIM

22 Summary ISOBUS for trailed sprayers was/is an interesting and important journey that was possible because of very good cooperation between different John Deere units and our external partner and allowed to develop a connectivity to both Deere and non-deere equipment but still allowing specific features within/on top of ISOBUS.
