Design of intelligent spraying system based on ARM9

Precision agriculture is well known as the combination of modern information of technology and intelligent equipment technology. With the application of differential GPS, precision navigation and intelligent spraying have come true. This paper introduces a intelligent spraying system based on ARM9 and differential GPS. We can draw a navigation map which contains the outline of the farm and navigation lines. It can precisely supply the information that where should be sprayed. The system send order to the controller which can define the state of the electromagnetic valve. Experiments show that the system performs excellent.
