Abstract
This paper presents a method of gathering and processing the spatial information for the variable sprayer in precision agriculture. A S3C44B0X microprocessor of ARM7 series was took a signal gathering and processing core for the variable sprayer. The outline of the farm was drawn by using the GPS (Global Positioning System) and the GIS (Geographical Information System). After the states of weed, plant diseases or insect pests in the farm were investigated by the manual or the sensor, the prescription for automatic variable spraying was provided by the plant protect expert system. When the variable sprayer worked in the field, the real-time signals of the position and the ground speed of the variable sprayer, the pressure and the flux in the sprayer pipeline, were gathered and processed. At the same time, the prescription were referred to the position of variable sprayer , the flux was controlled by opening size of nozzle of the electric control valve in the sprayer pipeline according to the prescription and working speed of the variable sprayer. The results of the field test shown that the method of data gathering and processing could be competent for the automatic variable spraying in precision agriculture.
