China is a large agricultural country with a wide range of farmland coverage.The amount of irrigation water is large,but the utilization rate of irrigation water resources is not high.The automation of agricultural irrigation and the low degree of intelligence are causing the waste of water resources to a certain extent and hindering China's agriculture.Sustainable development.In response to this phenomenon,BP neural network and fuzzy control are used to predict and control irrigation water consumption,and an intelligent irrigation system is designed based on ZigBee technology and 4G communication technology.The main research contents of this paper are as follows:Firstly,analyze the system requirements,and study the ZigBee technology and 4G technology,determine the network topology ZigBee network structure to sense the field data and execute the irrigation instruction,and complete the 4G gateway module with the host computer.The communication between the upper and lower machines is a system architecture scheme for the control center to analyze the on-site data and issue irrigation instructions.Secondly,the water demand characteristics of crops are analyzed and the water demand of crops is calculated according to the data.BP neural network and fuzzy control are introduced.BP neural network prediction model and fuzzy controller are established.Finally,the irrigation strategy flow is designed and The feasibility of the algorithm is verified.Thirdly,the architecture scheme of CC2530 ZigBee chip as the wireless sensor network node is determined,and the selection of peripheral hardware required by each node is completed according to the chip characteristics.In the circuit design work,the design of various nodes and their peripheral hardware circuits is completed,and the circuit principle is analyzed.Fourthly,the workflow of the protocol stack is analyzed in the system software design,and the corresponding workflow is designed for the functions of different hardware.In the design of the host computer platform,the platform design plan was first determined,and the organizational structure was analyzed.Finally,the design of each part was completed.The intelligent irrigation system designed in this paper combines ZigBee technology and 4G technology in communication technology.It combines BP neural network and fuzzy control in algorithm,which can make real-time and effective decision-making for irrigation,achieve water-saving purposes,and at the same time be agricultural.The automation and intelligent management of irrigation provide a reference and have certain practical significance.Figure [57] table [9] reference [53]...
