Design And Implementation Of ARM-based Intelligent Water-saving Irrigation System For Greenhouses

Agriculture is the basic industry of China’s national economy,and water conservancy is the lifeline of agriculture.Water is the so-called income and income,which fully shows that there is a close relationship between water conservancy and agricultural production.Therefore,in the case of timely adjustment of agricultural economic structure,to ensure the efficiency and quality of agricultural development and improve the utilization rate of water resources,scientific irrigation technology must be adopted to achieve efficient irrigation.Agricultural irrigation efficiency is one of the important contents of agricultural input-output ratio in China.In order to speed up the transformation from a large agricultural country to a powerful agricultural country,it is necessary to increase agricultural economic output and improve agricultural production efficiency under the premise of reducing agricultural input cost.In agricultural production practice,soil moisture content can directly affect the growth environment of crops,and its specific value is the main parameter to determine whether farmland needs irrigation.After years of experience accumulated in China,it is concluded that the main factors affecting soil moisture content are climate,soil,crops and so on.For greenhouse,this facility agriculture,climate conditions have a relatively small impact on soil moisture content.Based on the research on the development status of greenhouse agriculture in China,this paper designs an ARM-based intelligent water-saving irrigation system for greenhouses.The design of the system is based on ARM embedded platform,from the perspective of water saving and intelligent irrigation,realize the intelligent control of crop water saving irrigation in greenhouse.In the decision-making of irrigation,it is theoretically analyzed that the soil moisture content is a non-linear change process.In view of this difficulty in establishing an accurate mathematical model,the fuzzy control theory is introduced,and the water-saving performance of irrigation is improved by designing a fuzzy controller.Combined with the design of intelligent control,the human-computer interaction of irrigation is completed,and the soil moisture detection and irrigation instructions are issued in real time to realize the intelligent control of irrigation system.Intelligent irrigation system mainly includes three parts,namely terminal node,wireless communication module and server.Wireless communication module provides WI-FI network,which is the core of network control of the system.The terminal detects soil moisture in real time and feeds back to the server,and then the server sends irrigation instructions.The whole irrigation system integrates intelligent irrigation and fuzzy control theory,which can realize water-saving intelligent irrigation under the premise of reducing cost.Through the final test verification,the system designed in this paper can realize water-saving automatic irrigation in greenhouse environment,which proves that the research and design content of this chapter has certain market research value and promotion prospects.
