Design And Implementation Of Farmland Environment Wireless Sensor Network Monitoring System

In order to promote the healthy growth of crops and improve crop yield and quality,farmland environmental parameters have a great influence on the growth and yield of field crops.The information of crop growth environment should be grasped and the information of farmland environment should be collected and analyzed in real time.Based on the review of the status quo of the combination of domestic and external wireless sensor networks(WSN)and agricultural informatization,this paper focuses on the requirements and characteristics of precision,real-time,convenient operation and remote control for the collection of environmental parameters,The use of wireless sensor network technology,design and implementation of a set of solar energy for the supply of farmland parameters remote monitoring system.The system can monitor the temperature and humidity,wind speed,wind direction,soil temperature and water content,and light intensity in farmland environment,and provide data reference for crop nursery and cultivation to improve crop yield and product quality.In this study,solar energy as the energy supply,farmland environment formation of wireless sensor network using TI’s CC2530 RF hardware module and Zstack software protocol stack software platform to achieve the parameters of the environment to collect.Data transmission between the use of 3G-DTU module to achieve wireless sensor networks and remote servers,through the 3G mobile communication network for data exchange;The farmland environment remote data monitoring center is built by the browser/server(B/S)architecture.The MySql database is used as the storage of farmland environment parameters.The Jfinal framework is used to develop the web server on the Java platform.The remote monitoring center realizes the farmland Real-time display of environmental parameters,historical data query,historical data export and other functions.According to the monitoring requirements of farmland environment,the system in the design process of the sensor selection and modular design of the hardware circuit,and the sensor interface unified standard 485 bus communication interface,easy software development,but also easy to sensor loading and unloading operation.Finally,the monitoring system is tested,and the data collected from the nodes are calibrated by using the portable equipment such as the summit-595 air temperature hygrometer,the standard mercury thermometer and the TRIME-FM soil moisture content.The results show that the precision of the sensor nodes can meet the accuracy requirements of farmland information reference.At the same time,it is effective to adjust the node emission energy and the node spacing to improve the stability and reliability of network data transmission.After the test shows that the system monitoring data accurate,simple operation,stable operation,to meet the farmland environmental parameters of the monitoring requirements,in line with system design goals.
