Study On Wireless Irrigation System Based On ZigBee

China's per capita possession of water resources is low.With the rapid development of China's national economy,the water consumption of various channels shows a trend of rapid growth,and water shortage has become a common phenomenon of people's livelihood.In addition,China is a large agricultural country,and water resources are not evenly distributed geographically,so it is difficult to develop and utilize them.However,traditional irrigation methods are still used in many areas,which are prone to canal leakage,low water utilization rate and serious waste.Therefore,it is imperative to adopt efficient intelligent water-saving irrigation technology,which can not only effectively relieve water pressure,but also meet the requirements of developing fine agriculture and realizing modern agriculture.With the development and popularization of modern wireless communication technology,Zig Bee technology,as a protocol standard in wireless sensor network,is becoming more and more mature.With its excellent performance,Zig Bee provides low-cost,low-power and high-reliability solutions for many short-distance wireless communication applications.GPRS technology is gradually improved,and its coverage area is also increasing,and it can be distributed to almost all human settlements.It has the advantages of low maintenance cost,easy installation and remote data acquisition and equipment control.Of this paper is to use ZigBee wireless sensor network and GPRS wireless communication technology make a wide range of remote data acquisition system,combined with the soil temperature and humidity sensor,light sensor,air temperature and humidity sensors,such as the pipeline pressure sensor data timing acquisition,judgment,analysis and design the corresponding minimum system circuit and Zig Bee wireless sensor node,and in view of the terminal equipment of the low power mode,optimize the data sensor drive circuit design.Its low power consumption mode is mainly reflected in periodic dormancy and awakening,which reduces the energy consumption of terminal equipment by realizing low duty cycle.Based on the design of data communication protocol,the data sensor driver realizes the reasonable collection of agricultural data through the interactive program with the host computer.The intelligent irrigation system is managed by the local and remote working modes.The local mode is automatically managed and irrigated by the sensor according to the data and the set threshold value.Remote mode is based on the sensor data and setting threshold,to take the initiative to report the equipment parameters and real-time sensor data,by the remote control side is analyzed,then distributed control valve command,the scientific management of farmland soil drought,remote automatic monitoring records,and intelligent irrigation,farmland soil moisture fully automatic monitoring and intelligent water-saving irrigation.This design in the end under the Zig Bee and GPRS wireless communication mode,combined with single-chip computer technology and intelligent sensor technology,to realize real-time monitoring,recording of the farmland soil moisture and soil moisture sensors,start the solenoid valve,meet the requirement of modern economical irrigation,and in the agricultural informationization and modernization of farmland management has the very good application value.
