An agricultural irrigation system based on GIS and RFID

To solve the serious problem of water waste for agricultural irrigation in our country, an agricultural irrigating system is developed by combining GIS with RFID which charges according to water flow. The system implements the quantitative charge and automatic accounting by AT89S52 micro-controller, RF card and MF RC500 as its core components; and implements the visualized management which can display the irrigation condition in specific area and quantitative information of user´s water consumption by utilizing the GIS and SQL DB. This system helps to overcome the problem of single performance and incompatibility of devices, as well as the unavailability of sharing data etc. The system has simple operation, friendly interface, and high performance-price ratio, which can be widely applied in irrigation areas and irrigation reservoirs, and has a wide application prospect.
