Characteristics of FS














Development and application in agriculture is efficient Integration of sensors, network, camera, battery, solar power, (wireless) communication and software Can be distributed deployed in field for automatic monitoring and data collection Hierarchical structure, tree structure The networking, identification, communication, data capture usually by the root node and its software Infrastructure is through the Internet Easy to understand and develop the application of agricultural


Technology, cost, ... 3

Some FS applications in Taiwan

Examples


Farm monitoring and data collection automation






Chicken farm Paddy field

Integrated farming systems

5

FS in the chicken-farm (K. S. company)

6

Chicken farm: monitoring, data recording and management automation

7

Platform of integration



Facilitate the automation of the farm FS SN + in farm devices + software → networked, scalable, efficient, flexible, can be intelligent





Good platform to development “intelligent” functions

“Friendly” development environment 8

FS in rice applications

Rice quality contest




Quality puzzles
Good farmers + good place + nearby paddy field + same variety → different qualities
How the environmental factors affect the rice quality in the rice growing stages
How to improve the quality of rice farmers should adopt the advanced management

Data collection


FS deployed in the NCHU’s experimental rice field for rice multimedia data collection





Microclimate, soil water content, sunlight intensity, temperature, leaf color,..

Extracting parameters


Growing degree day, modified growing degree day, accumulated illuminance of different rice growing stages 13

PFS systems

Simple node

High resolution Sollar cell mode

Multi-functions

14

Paddy field data acquisition

From the rice seedlings transplanted to mature harvest. Spring & fall crops 15

Quantification of farmer’s skill

Soil moisture (VWC) -flooded -irrigated –sunbaked (TK9)

Temperatures

Using the data of soil moisture content, temperature, humidity, sunlight, leaf color to understand skill farmer’s irrigation, management, fertilization, etc. stratagems

16

Advance parameter extraction

Rice plant characteristics study through the FS system Chlorophyll vs. reflection colors 17

IOT

Internet of things (the future)








“...the Internet of things, also known as the Internet of objects, ... as a self-configuring wireless network of sensors... ” - Wikipedia “A global network infrastructure, linking physical and virtual objects ... offer specific objectidentification, sensor and connection capability ... federated services and applications... data capture, event transfer, network connectivity and interoperability” – CASAGRAS “Seems more than the Skynet in the Terminator”

IT technology development to IOT

From: Broadband Business Forum/EXPO COMM Italia 2009Rome, Italy, 24 –25 November 2009

IOT structure (ETRI, CASAGRAS)

ETRI in CASAGRAS

Supporting technologies













Identification Technology Internet of Things Architecture Technology Communication Technology Network Technology Network Discovery Software and algorithms Hardware Data and Signal Processing Discovery and Search Engine Relationship Network Management Power and Energy Storage Security and Privacy Technologies 23

Important application areas












Public security: electric power network, intelligent disaster / crisis management in city, disaster surveillance, military material U-health care, structure health monitoring Public transportation Industrial: production, petroleum, coal mining Energy efficiency, environmental protection: water resource, atmosphere, ecology Logistics Agriculture 24

Agriculture perspective












How could the new technologies affect agriculture? What emerging innovations, technologies and market trends will be seen and likely to emerge in the future to agriculture? How will IOT empower farmers experience and capabilities? What new service architectures will be provided in agriculture? Privacy and data protection policy, unauthorized access 25

Need a broad and robust food safety structure

Some food safety crises in Taiwan

Pork from sick and/or dead swine went into market (~2005~)

Antibiotic residuals in fish (2006)

(disgusting ?)

26

IOT solve BSE problem

Melamine-milk

BSE

27

Dairy farms equipments with WMSN functions

Automation equipments used in dairy farms are good data acquisition systems

29

Milk quality data acquisition by milk meter + ICT

30

Dairy farms: Online dairy cow mastitis detection system

Milk quality inspection automation

Quarter-milk conductivity (QMC) meters (smaller)

31

Automatic take-off and milk quality systems

Improve automation management systems with ICT ability remote, immediate, transparent, intelligent... 32
