Zigbee Technology Research And Application Of The Automatic Monitoring System Of Agriculture

In recent years,the rapid development of science and technology continuously push forward the industrial,agricultural and other fields,and enhance the degree of automation of these fields.Our country is a big agricultural country,agriculture is important economic lifeline,the country's stability are guaranteed long-term stability,so the level of automation of agriculture are related to the major issues of the people's livelihood in our country.As a brand-new development direction of information science domain,the development of WSN has caused widespread attention of the academic circles and the industry due to the greatpromise and the potential with the various applications.it is the smart network system which can implement the data collection,data confusion and transfer application.Wireless sensor networks has widely application foreground ever in national defence or other fields.Especially in greenhouse,precision framing,irrigation in farmland,pasturage and breed aquatic agriculture application has great value of application and extendtion.The study of this technology will drive the tenor of our country's information construction and advances the development of the related domain and subjects,and steps our country's national power.ZigBee technology is a new short-range,low complexity,low power,low data rate and low price transmission wireless sensor network technology,it is particularly suited to the farmland collection and control system which has small data throughput,not easy at long distance cabling, data acquisition wide coverage,inconvenience or frequent replacement rechargeable battery. This thesis on the basis of the study of wireless sensor networks in particular of ZigBee technology,carried out research on wireless automated monitoring of the agricultural development of control systems based on the ZigBee wireless sensor networks.This paper analyzes the wireless sensor network technology and network architecture and application value,studies ZigBee technology specific protocols and related concepts which are based on the IEEE802.15.4 standard.The third chapter introduces the whole design scheme.On this basis,we make the whole design scheme of the farmland collection and control system based on ZigBee technology and the corresponding ZigBee node hardware and software research and development.The system utilizes JN5121 module as its core module,this module integrates a low-power,low-cost wireless micro-controller and a wireless transceiver which is compatible with IEEE802.15.4 standard and produced by Jennic company.Base on the study of wireless technology,sensor technology,embedded computer and power design technologies,combining the newly production of the world,we complete the whole system design and development.After test and application experiments,the farmland collection and control system based on ZigBee wireless sensor networks technology shows good performance in low power and stability. The result of the experiment was also show that the wireless and network of sensor will bring a lot of convenience for agriculture information.Bring the wireless sensor networks into agriculture domain has a landmark meanings for agriculture.
