Agricultural wireless sensor network development and applications
IT makesUbiquitous & Automatic • ICT and wireless technique development • Measurement instrument getting smaller, modular, networked, 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
Price vs. performance:agricultural wireless sensor network • Crossbol: integrated commercial product • Field-Server: performance & functions developing with software, sensors, camera, wireless, even solar power • Sensor module: web-AD/IO card, temperature, humidity, sunlight, 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
Sensors • Humidity: (0-100% 1% RH) TDK CHS-UPS • Temperature: ( 0-100 1C) LM35DZ • NH3: (0-30PPM) TGS2602 • CO2: (300-5000ppm) HS-135 • Light (indoor): CDS • Light(outdoor): solar cell • Camera: CCD and CMOS, IR
Automatic and nonstop information collection and monitoring Agent program Data collection
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 distance 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, experience
Application: ubiquitous and automatic information collector Monitoring, Management, Distance control
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.
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
Example: Food safety issue • Transparent superintend: safety and quality check by consumer, impartial third party, inspector in regularly, remote, routine basis
Using Field server User interface/Broker for internet monitoring and management /Traceability system Farmer Remote monitoring management Consumer Production process trace 1. Quality 2. Epidemic disease drugresidual 3. Consumers’ confidence Third partysuperintend
