| Since entered twenty-first century,the Internet has come into thousands of households.The application of the Internet of Things,such as the key technologies of sensing technology,network communications technology and embedded computer technology,has quietly changed the way of people's life.And the agricultural networking technology,which based on the technology of the Internet of Things,has also been favored by the world.By using the key technologies such as Internet technology,sensor technology,large data technology,Internet of Things technology and embedded technology to agricultural production,can not only promote the development of rural economy,help the farmers to raise their income,narrow the gap between urban and rural areas,but also improve the production efficiency,ease the agricultural pressure and burden.Based on the research of the present situation and future trend of domestic and international agricultural networking,this paper deeply studies the design model,concept system and key technology of the Internet of Things.On the standard of the design model of Agricultural Internet of Things,this paper designs a set of monitoring and control system of the Internet of Things based on the key technologies of the Internet of Things,such as Zigbee wireless technology,CDMA 3G technology and embedded technology.This paper mainly combines the key technologies of the Agricultural Internet of Things and surroundings with the agriculture.In view of the problems of complex control,data transmission distance,high wiring cost and poor system mobility in agricultural data collection,this paper has developed a wide area network based agricultural network monitoring system.Considering the CS architecture design pattern of the mobile Internet,the system has developed the client-server-gateway based agricultural information collection system.The whole system adopts the wireless transmission mode,which eliminates the complicated wiring steps and high wiring costs. |
