Drones, AI making cattle counting a dream
PGG Wrightson has launched a new stock-counting service using drones and Artificial Intelligence (AI), which it says removes all the hassle for farmers, while achieving 99.9% accuracy.
Probably because it means customers will be inclined to stay with a one-colour fleet to eliminate compatibility issues.
Indeed, for as long as we’ve used GPS guidance and yield monitoring/mapping systems, farmers have been dogged by the inability of different brands to ‘talk’ to one another.
But Johannes Heupel, a clever grain farmer (2500ha) in Edmonton, Canada, who runs John Deere tractors and Claas Lexion headers – and is well versed in tech – has developed the Agra GPS-JD Bridge. This connects info from most tractor, header and forager brands to talk to JD’s guidance systems and display screens.
Put simply, the system will allow users to run JD screens and receivers in a competing header or harvester. This enables it to provide auto-steer, use existing A-B and boundary lines, and collect and display yield data.
The technology only uses only 32kb of memory space because its prime focus is data transfer. Any data required for further analysis can be sent to the cloud, a farm computer or JD’s myjohndeere app.
Heupel analysed the codes in the CAN bus systems of most mainstream manufacturers. He then created the device that translates that info into Deere’s software language, to act as a conduit as machines move across the paddock.
In Heupel’s case, the monitor thinks it’s in a John Deere header, although its actually in the Claas Lexion, so all data is translated and processed as normal.
As it’s designed to process only auto-guidance and yield monitoring, there is little chance that overall machine management will be on the radar, given that machines carry such a vast array of differing functions between models and brands.
Systems have so far been designed for Claas, Fendt, MF, Cat, Versatile, Krone and Case Quadtracs.
What is a ‘CAN’ bus?
CAN bus is an integral network designed to transmit data according to a set of protocols.
Controller area network (CAN) is the protocol commonly used on agricultural vehicles as it’s designed to cope with harsh environments.
Built to a global standard, the network allows different control units to talk to each other, sending messages from different parts of the machine to report on function and performance.
Generally, companies don’t provide coding information for how to decipher the documentation systems, which means every piece of data is written in a near-alien language. The exceptions are JCB and Versatile, which provide information to explain what the code being sent between the machine and its control box means.
Deciphering CAN bus information is a difficult procedure due to the thousands of pieces of information sent every second, and because each manufacturer will run different documentation systems, so no data formats are compatible.
