Design Of Intelligent Irrigation Terminal Machine

The shortage of water resources of our country is serious,some areas of the groundwater level declining year after year.Through the combination of control and management,standardizing the agricultural irrigation water pricing system,in the aspect of agricultural irrigation,guiding people to use water scientifically and to save water,and gradually realizing the precision irrigation is an inevitable development direction of agricultural modernization.In this paper,we have been combined RFID technology and GPRS technology to apply in the field of intelligent irrigation and we develop the agricultural irrigation control terminal,to achieve irrigation water to remote measurement on the computer,control and management functions.For the modernization and information of agricultural production,it provide a kind of technical support,but also for the realization of agricultural precision irrigation to provide information basis.This paper mainly studies work:1,On the basis of deep research on the current situation of agricultural irrigation water use,the management mode and demand of water,we designed the overall technical scheme of intelligent irrigation terminal and selected the type of main devices such as main chip,GPRS chip,flowmeter and cardreader.2,Designed a circuit of terminal machine,which is singlechip as the core,including intelligent irrigation terminal control board power module,card reader module,GPRS data transmission module and so on.3,According to the functional requirements and operation flow of the intelligent irrigation terminal machine,the application software such as reading or writing card,water metering,GPRS information transmission,information management and water control are designed.4,The embedded real-time operating system UCOS-? is transplanted to the main chip,and the various of tasks is software programmed in the UCOS-? system.5,The experimental prototype of the terminal is developed,and the designed hardware and software are debugged and tested.The test results show that the main functions fully meet the design requirements.
