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

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

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

19

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
