摘　　要：为充分掌握土壤水分、环境温度、环境湿度与光照情况,实现适时、适地、适量灌溉,施肥与远程管理,设计了基于无线传感器网络技术,结合GPS定位(用于WSN锚节点的定位)技术的果园数字信息采集与管理系统。该系统通过相应的传感器采集果园微气象信息(包括土壤水分、环境温度、环境湿度与光照等),并在无线传感网络的支持下,先结合GPS确定少数锚节点的位置,再根据锚节点计算出未知节点的相对位置,从而确定所有节点的位置信息。采集到的信息经转换后直接接入ES(专家系统),用ES输出辅助决策信息(状态评价结果,包括精确灌溉与环境控制建议等)给用户,实现了果园数字化管理的可视化、便利化。To realize fertilization and remote management,irrigating timely and moderately,by grasp the soil moisture,environmental temperature,humidity and lighting conditions fully.Orchard digital information collection and management system was designed based on wireless sensor network technology,combined with GPS positioning(used for WSN anchor node location).The system can collect orchard micro meteorological information(including soil moisture,environmental temperature,humidity and illumination,etc.) with the support of wireless sensor network,and determine the position of minority anchor node with GPS first,then calculate the relative position of unknown nodes according to the anchor node,so as to determine the location information of all nodes.The information collected can be sent into ES(expert system) directly after converting.And the decision-making information(including precise irrigation and environmental control suggestions,etc.)is provided to users with the decision-making figure form in order to realize the orchard digital management of visualization and facilitation.
