基于GPS的农田多源信息采集系统的研究与开发

Field multi-source information collection system based on GPS for precision agriculture

及时准确地获取农田小区影响作物生长的环境因素多源时空差异性信息 ,是实施精准农业的关键步骤。研究开发基于 DGPS及便携式 GPS的农田信息采集软件 ,集成较为成熟的田间信息采集传感器硬件 ,能够采集田间地物分布、作物生育期苗情状态、杂草分布、病虫害发生情况、土壤肥力等多种基于精确空间位置的实时动态信息 ,包括数字照片和数字视频等多媒体属性信息。使空间定位、属性记录和导航实施过程相结合 ,初步实现了农田信息获取的自动化。

It is the key step for implementing decision based Precision Agriculture to collect timely the multi source spatial temporal variant information that influences crop production in the field. By integrating field information collection sensor hardware, the field information collecting system based on DGPS or portable GPS receiver is developed, which can gather multi source field dynamic information with accurate position information such as field feature distribution, crop status throughout the production season, field weeds, pest and disease distribution, soil nutrient variability, as well as some attribute information of digital picture or digital video. This system can combine the processes of positioning, attribute information recording and implementation, which realize field information collection automatically.
