1 Precision Farming Challenges in the 21 st Century I SO wish it were that easy! The challenge of ISOBUS Implementation Peter Nelson Engineering Director RDS Technology Ltd.

2 What is ISOBUS? ISOBUS is a standard communications protocol conceived specifically for linking agricultural tractors, implements & software ISO International Standards Organisation BUS A CAN based communications network

3 ISOBUS History Europe LAV Munich LBS > LBS North America SAE J1939 Truck & Bus standard ISOBUS >?? based on LBS + SAE J1939

4 Management of ISOBUS Industry Groups DLG/ VDMA in Europe NAIITF in USA Combined as AEF in 2008 ISO Set the standards ( ISOBUS Standard under secretariat of VDMA )

5 ISO ISO consists of the following parts, under the general title Tractors and machinery for agriculture and forestry Serial control and communications data network: Part 1: General standard for mobile data communication Part 2: Physical layer Part 3: Data link layer Part 4: Network layer Part 5: Network management Part 6: Virtual terminal Part 7: Implement messages application layer Part 8: Power train messages Part 9: Tractor ECU Part 10: Task controller and management information system data interchange Part 11: Mobile data element dictionary Part 12: Diagnostics Part 13: File Server Part 14: Sequence Control

6 ISOBUS Aims Reduce Cab Clutter & Simplify Wiring

7 ISOBUS Aims Standardised Data Formats -ISOXML

8 ISOBUS Aims Standardised Data Formats -ISOXML

9 ISOBUS Aims Share common inputs Forward Speed PTO Speed Hitch Position GPS/ Guidance / Section Control Work Status

10 ISOBUS Aims Integrate tractor, implement, farm management Headland sequence control PTO Speed Forward Speed Hydraulic Control Precision Farming Variable Rate plans and records

11 ISOBUS Aims Enable modular integration Ex: A sprayer control system comprises:- Spray rate regulation Boom height / levelling Steering axle / drawbar Section Control Crop canopy scanner Could each be from a different supplier but integrated into a single system

12 ISOBUS Overview FMIC Software Aux. Control Tractor ECU DGPS (NMEA 2000 ) Virtual Terminal Task Controller File Server Implement ECU Implement ECU ISOBUS Connector

13 ISOBUS Overview Virtual Terminal Task Controller File Server

14 ISO Virtual Terminal ( Universal Terminal ) Conference convener defines Display size, resolution & colour User interface no. of keys and navigation Language Units Management of participants VT Types 1,23 and 4 Type 4 required for Aux. controls & mapping

15 ISO 11783

16 ISO Task Controller Gofer or messenger Passes data as ISOXML files between FMIS& VT VT& Implement Sends a plan of resources to be used Collects record of resources used May define implement dimensions

17 ISO File Server A means of exchanging proprietary ( non- ISOBUS ) files between elements on the bus. Ex. Fertiliser data from a web site to the spreader control system.

18 Tractor ECU ISOBUS Overview

19 ISO Tractor ECU Basic TECU provides speed, PTO speed. Includes basic ISOBUS cable harness and connectors. Advanced TECU is bi directional and allows control of tractor speed etc.

20 ISO Implement ECU Application specific control unit. Contains all software to control the machine and the ISOBUS Object Pool(s) to link to the UT. Bridge Link converts stand alone CAN based system to ISOBUS.

21 ISO Auxillary Control Unit Joystick Switch Box ISOBUS Shortcut Button

22 ISO Live standard Still evolving to encompass new technologies At 2013 Plugfest there were 22 VTs and ~35 Implement ECUs on test 2013 Plugfest was the first to include the Task Controller tests Only 1 VT included a File Server

23 ISOBUS Challenges The Perception Media appeal Plug and Play A solution to PF compatibility issues??

24 ISOBUS Challenges The Perception

25 ISOBUS Challenges The Demand Major manufacturers ISOBUS VT equipped tractors Customer then expects ISOBUS implements Perceived cost savings So our oem customers demand that we supply ISOBUS systems ( as well as conventional stand alone systems )

26 ISOBUS Challenges The Reality ISOBUS has reached a maturity and adoption level where it is now expected and demanded on new machinery. So what s the problem?

27 ISOBUS Challenges The Costs of Development Getting Started Buy ISO Standards 1300 Join AEF 2000pa Buy VT 3000 Object Pool Edit s/w 3000 DLG Test s/w 1500 Vector CANoe ISOBUS Training??

28 ISOBUS Challenges The Costs of Development Development Costs Stand alone development ISOBUS development Testing (DLG) 2000/day Conformance testing 6000/test Maintainence to evolving standard

29 ISOBUS Challenges Development Tools Object Pool Editing software

30 ISOBUS Challenges Development Tools ISOBUS Diagnostics / Test Tool DLG P-Convert

31 ISOBUS Challenges Development Tools ISOBUS Diagnostics / Test Tool Vector CANoe

32 ISOBUS Challenges Practical Constraints Ergonomics Multiple screens Operator Manuals Touch screen / scroll wheel Soft Keys Support Support staff require knowledge of multiple VTs / TC etc. Who gets the phone call?

33 ISOBUS Challenges Certification

34 ISOBUS Challenges Innovation Main differentiation between brands is the electronics ISOBUS imposes collaboration between competitors New technologies must be embraced by the standard ISOBUS data is not secure

35 ISOBUS Challenges Future-proofing Video input not possible over CAN Bus Loading / speed Tablets/pads/ Apps Wireless communications ISOBUS 2???

36 ISOBUS Challenges Conclusions ISOBUS is now and established, integral part of agricultural machinery ISOBUS will continue to evolve It is not compulsory It is not always appropriate There will still be ongoing compatibility issues.
