Configuration Of Wireless Sensor Network On Collection Data Of Field Information

21 centuries agriculture are an informational agriculture, deepen information technology being imperative in application in agriculture field. Being skill in the precision agriculture is the new tidal current that the world agriculture develops nowadays , the only way which must be passed being future our country sustainable development in agriculture. Quickly and effectively gather and describe the impact of the crops grow in the space environment variable information, that is the basis of precision agriculture development.Development precision agriculture require that the large amount of effective accurate and in time Farmland environment data and the crop growth data. The perception being able to be synergetic, collects the wireless sensor network with information of marriage partner handling middle perception of network coverage area , announces and to the observer. Use wireless sensor network to monitor the growth of crops,to collect the light exposure,humidity,temperature and other information to provide convenience for agricultural technicians to adjust the crop plantation's growing conditions,in this way to guarantee the optional growing environment for crop plantation in any great degree,and the harvest of the crop.Main contents as follows:1. The authors analyze the wireless sensor network research status, that the wireless sensor used in the agricultural sector has vast potential.2. According to the characteristics of farmland and the environment, to develop a wireless sensor network architecture consists of sensor nodes, network coordinator, the composition of the base station and terminal. And proposed for field information collection by the sensor element of sensor nodes, wireless transmission unit, micro-controller unit and power supply unit composed of four parts.3. Analysis of ZigBee technology and protocol architecture, respectively, from the physical layer, medium access control layer, network layer and application layer in detail.4. Temperature and humidity data acquisition for field construction protocol based on ZigBee wireless sensor networks. JN5139 chip with a sensor board hardware platform to build networks; According to the network coordinator, routers, end devices task of three different nodes, using Code:: Blocks to complete the software code editing and compiling works; Different functions will be completed by Flashgrammer binary code downloaded to the corresponding device node, Then node in accordance with the programming process in its internal auto-run, complete set of functions; During device function definition, to consider a wide range of content, including its communication mechanism, routing scheme, and sleep, time synchronization, etc.After the network devoted to corn and wheat fields and under the temperature and humidity information collection. The results show that the wireless sensor network in normal operation, the collected data with high accuracy and reliability to achieve the desired goals, and a strong value.
