Design And Realization Of Intelligent Agricultural System

In recent years,with the development of the Internet of things and cloud computing technology and its application in depth,people are moving towards a digital and networked intelligent society.Internet of things technology has a wide range of applications by virtue of its efficient and reliable information transmission in modern agriculture,through the cloud computing platform accurate data processing and judgement,realized the transformation gradually from traditional agriculture to modern agriculture.Through the analysis about the background and significance of the intelligent agricultural system and the summary about the development status and future trend of intelligent agriculture at home and abroad,obtained the overall design scheme of the system.This system used three layers of IOTs architecture.Firstly,in perception layer,ZigBee wireless sensor network was constructed based on the STM32 micro controller,which is responsible for the acquisition of the agricultural environmental parameters in hardware layer and the implementation of the decision information.Secondly,Network transport layer used WiFi and GSM network technology to realize the interaction between perception layer and application layer.Finally,based on IOTs cloud platform,the application layer realized the perceptual processing,storage and decision-making of sensor data.At the same time,the decision information issued to the implementation of the perception layer devices in real-time,heating and ventilation control of agricultural environmental information intuitive to users.In the system test experiment,tested thestability of wireless sensor network and system functionality,According to the experimental results,found a solution that ZigBee and WiFi network channel interference in the 2.4G band,it ensured the normal and stable operation of the system.Experimental results show that: this system can ensure stable and reliable data transmission,can view real-time sensor data and control agricultural equipment in the agricultural field through the mobile or web client.When the data of sensor was abnormal,system will trigger level 2 fault alarm mechanism,achieved the design goal of intelligent agriculture prestage.
