| The farmland in China is vast and the fresh water resources are relatively deficient.The modern water-saving irrigation technology is still under development and the process is relatively slow.In this paper an intelligent agricultural irrigation control management system is designed.The system is for intelligent remote water management and it is implemented by computer and its designed idea is ’centralized management decentralized control’.The irrigation technology of farmland domestic and overseas,and the requriement of the management and control of irrigation water are fully analysis first.The core content of this paper is to design hardware circuit of ATmega64 lower computer control program and computer management software.The lower computer can implement the function of contactless IC card data reading and writing,the water intake unit control,the water data remote reporting,the clock module,the data drop storage.To prevent the Mifare technology from being cracked,the ATmega64 program has the function of anti crack IC card to protect payment information and data security it can also protect IC data from read and write failure and to prevent the water supply process of an accident so it can ensure the safety and reliability of the operation system.The system uses the GPRS technology the water information of each well can be collected remotely and dynamically including water time,location,user and water consumption.Computer irrigation management software is also designed.It can implement the modern management of data information,including the water information of the pumping well and the information of the user’s rechargeable card and also has the functions of new user registration,IC card recharge,various inquiries by reading the background database file.According to the field test,the function of intelligent remote water getting system is realized,and the system has been applied in monitoring and management of agricultural irrigation. |
