Research And Application Of Micro-drip Irrigation Monitoring System In Tea Plantation Based On Fuzzy Control

At present in China,agricultural water accounts for more than half of the total water,of which agricultural water is almost for irrigation water.However,the efficiency of agricultural irrigation water is low.The excessive irrigation of some areas lead to lower production of agricultural products and the decline of quality,at the same time,damage to soil nutrients.In some places,the serious lack of water due to the crops can not grow normally.Houkui is the specialty of Huangshan,this area has enough water,but the efficiency of irrigation is still low,the management of tea garden should be improved.We used sprinkler irrigation and drip irrigation,it is suitable for irrigation of te plants area.With the development of the Internet of Things,agricultural informatization is the inevitable trend of agriculture.In this paper,we have the research in the experimental site of the tea garden of Houkui in Huangshan.The wireless sensor network has been applied to acquire real-time information of tea plantation,and the design of the control rules are based on fuzzy control.Then we developed the monitoring system platform for the tea garden,so that we can monitor the climate and the growth of the tea plantation anytime.The intelligent management of the tea garden has been basically implemented through the experiment,and it provided support for the sustainable development of the local tea industry.The monitoring system platform of micro-drip irrigation for the tea garden combined wireless sensor network and fuzzy control.On the basis of tea expert system,we develop the remote monitoring platform,so that we realized the information management of intelligent irrigation and remote real-time monitoring of tea garden.The main contents of this paper include three aspects:1.Information collection of tea garden.This part mainly designs the distributed multi-sensor network and real-time remote transmission of the information.According to the analysis of the environment of growth of tea plants from expert system,combining the key factors with tea plants related,placing sensors into soil with different depths to acquire information about tea plants and environment.First,we compile acquisition program by the central controller.Then,the collected information will be transmitted to the platform of the system by the GPRS.The information will be displayed in real-time in the platform.2.Design of fuzzy controller for irrigation of tea garden.Fuzzy control is one of intelligent control.Expert system of tea plants supports for making decisions and fuzzy control is used for making rules,then they can help realizing the intelligent irrigation of tea garden.This part mainly includes these follow aspects.First,the selection of input and output variables should be decided.Second,the fuzzy processing of variables.Thirdly,the choice of membership function.Fourthly,the defuzzification processing of variables.Finally,we can obtain the control rules.3.The development of micro-drip irrigation monitoring System platform.The significance of the platform is providing support for real-time display of collecting information.We use MySQL for receiving and storing information on the background server.The information of plantation and management of tea garden will be displayed in the platform,and we can get the real-time data and historical changes from the curvilinear graph.The system provide scientific support for the optimization of the fuzzy controller and the management of tea garden.
