Based on Wireless Sensor Network Digital Information Acquisition and Orchard Management System

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.
