Development And Research Of Intelligent Irrigation Control System In Orchard Of Changning City

Today’s water resources have developed into an important scarce resource.It is not only closely related to people’s lives,but also an important strategic issue that restricts the long-term stability of the country,the sustainable development of society and the rapid development of the national economy.Today,when water resources are extremely scarce,traditional agricultural irrigation methods are not suitable for sustainable agricultural development.Today’s agricultural irrigation methods should be developed in the direction of intelligence,energy conservation and water conservation.The use of intelligent irrigation methods not only helps to reduce labor costs,but also meets the great purpose of saving water resources.It has become an effective means to achieve agricultural modernization and alleviate water resources problems on a global scale.In large-scale centralized agricultural production,orchard agriculture is undoubtedly the most representative type of agricultural produ-ction.Therefore,aiming at large-scale orchard agriculture in Changning City,this paper uses ZigBee,GPRS,sensor network and Web Internet technology to design a set of intelligent detection and irrigation control system for large orchard agricul-ture.The main research contents of this paper are as follows:(1)Based on the research status of agricultural irrigation at home and abroad,and China’s basic national conditions and agricultural production characteristics,the overall design scheme of the intelligent irrigation control system for orchard is established,which combines remote control,remote data acquisition,wireless sensor network,information feedback and drip irrigation control.Build a multi-functional integrated agricultural automation control system.(2)The evapotranspiration of the reference crops was calculated by the internationally accepted comprehensive method,and the water demand of the orchard fruit trees was calculated.According to the water requirement and crop coefficient of each orange growing period,the amount of irrigation water and the irrigation time interval required for the number of oranges were calculated.(3)Designed the hardware of the orchard intelligent irrigation control system,and finally determined the use of ZCW-2 zero pressure start solenoid valve,SWR-3 soil moisture sensor,ATmega128 microcontroller and ZigBee network terminal.(4)The software of the orchard intelligent irrigation control system was designed,and finally the CC2430 based on ZigBee2010 protocol was used as the software design of ZigBee wireless network.(5)The Internet dynamic webpage development technology of the intelligent irrigation control system of the orchard was designed.Finally,the ASP.NET technology was developed to develop the application server and Web server of the system.The programming language chose C#language and the development environment was Visual Studio.NET 2008.And use ZedGraph for graphic drawing.
