IT makesUbiquitous & Automatic
▪ ICT and wireless technique development▪ Measurement instrument getting smaller, modular, net
worked, wireless, economic, and low power consumption
▪ Wireless communication▪ 802.11, Bluetooth, ZigBee or GSM
▪ Wireless sensor network (WSN)▪ Distributed multi-channel remote monitoring and data
collecting time-shearing system
7
Price vs. performance:agricultural wireless sensor network
▪ Crossbol: integrated commercial product
▪ Field-Server: performance & functions developing with s
oftware, sensors, camera, wireless, even solar power
▪ Sensor module: web-AD/IO card, temperature, humidity, sunlig
ht, CO2, ammonia, moisture content, meteorological sensors
▪ Wireless comm.: 802.11a/b/g AP
▪ Vision: CCD, CMOS, IR-camera
▪ Power consumption: low
8
Taiwan web-AD/IO engine
▪ web-AD/IO card▪ 10cm x 7cm, 7.5-12V DC
▪ RJ-45 and RS-232 connectors
▪ Single chip computer▪ PIC18F6520
▪ TTL I/O: 12 ports
▪ A/D: 10 bits, 5V, 8 ports
▪ Ethernet controller ▪ RTL8019AS
▪ IP & MAC programmable

Wireless communication ▪ 802.11b/g:Wireless internet infrastructure, laptop
▪ Support TCP/IP 、 Ethernet, usually 2.4GHz▪ 802.11b/11Mbps 、 802.11g/54Mbps, speed 1Mbps transmission d
istance about 570 meter ▪ Router/Bridge types
▪ IEEE802.15.4 (ZigBee) : home set, PC, game box, toy▪ 2.4GHz, 868MHz (European), 915MHz (US)▪ Transmission distance about 75 meter, 20kbps ~ 250kbps▪ Low power consumption
▪ IEEE802.15.1 (blue tooth): m-phone, printer, medical equipment▪ Short distance, 2.4GHz
▪ GPRS: bandwidth up to 160 Kbps▪ Criteria: bandwidth, accessible, long term cost, technique popularity, e
xperience

Some FS
Applications and Projects
15
Application: ubiquitous and automatic information collector
Monitoring, Management, Distance control
Poultry and livestock management applications
17
Agricultural automation platform and control center
▪ Front module: Web-I/O + SSR + wireless AP
▪ Confirmation module: FS (vision and movement
feedback, middle connection)
▪ Control module (remote): broker, z-transform,
intelligent control algorithm, etc.
18
Remote control application:water sprayer cooling system

Food safety system issue:Agriculture information input
Farmers and operators to use computers is difficult Farmer need information but computer, farmer
earnest about profit but troublesome computer learning
SOP ? Tables ? Manually ? Static information ?
Field server provides Automatic, dynamic, intelligent able agriculture
data collection
20
Example: Food safety issue
▪ Transparent superintend: safety and quality check by consumer, impartial third party, inspector in regularly, remote, routine basis
