IN COLLABORATION WITH

Smart Farm

• Informed Farming• Precision agriculture

– Sensors, information system, decision support systems

– System exists within a farm-gate

• Connected Farm• Devices in the farm are connected with each other and the world using

internet

• Farmers are connected to the farm devices, other farmers and experts

• Things (e.g. Cattle) in the farm can be monitored remotely.

• Integrated Farm• Includes Farmers in the supply chain - suppliers, logistics, consumers – back

to the farmers to complete the loop.

Kirby ‘Smart’ Farm

• Location Armidale, NSW, Australia

• Farm Area: 739 Hectares (or 1827 Acres)

• Smartfarm Area: 269 Hectares (or 665 Acres)

• Livestock: Cattle, Sheep

• Devices: 100 Soil Sensors

2 Weather Stations

Cattle ear tags

Flex, Alix PC, 3G Modem etc.

What do farmers want?

• Measurement data produced by 100 sensor every couple of minutes?

• Weather measurement produced every couple of minutes?

• Cattle location updated frequently?

• Farmers are interested in the alerts about the things in the farm.• Cattle leave the farm

• When to sow

• Current market value of their livestock

• Soil in a paddock is compacted

• Researchers/Experts are interested in the data.

Data Dimensions

Presentation title | Presenter name8 |

GSN Extended

• Geo-Spatial Analysis• Implemented using R and Java packages

• Event (Alert) Processing• Extended GSN to process event descriptions and produce alerts

• Synchronous and Asynchronous events

• Farms can create their own events

• Semantic Web Enablement• Sensor data stored in MySQL

• Linked data are produced using defined URIs

• Statistical data are stored in Virtuoso triple store

– Provides open access to everyone, analyse data using SPARQL

– VisualBox and Google APIs for visualisation

Future Works

• SPARQL based access to dynamically generated data cubes

• Machine Learning over the Data

• Integrate satellite data

• Social Farming

Presentation title | Presenter name15 |

Machine Learning Opportunities

• Cost of Sensor Networks

• Variations are possibly correlated and predictable• Soil variation, elevation -> soil ec, temp, vwc

• BOM forecast -> farm weather

• Data collected over last 2 years • Use to generate predictive model

• Produce sensor data without sensors.

Because data from Sensor networks in farms worth more than the sensor networks!
