Abstract

The invention discloses a soil humidity sensor network system. The soil humidity sensor network system comprises soil humidity sensing equipment used for obtaining a surrounding soil humidity value and an air humiture through soil humidity sensors connected with the soil humidity sensing equipment and conducting data processing on the soil humidity value, data collection equipment used for receiving data from sensing nodes and transmitting the data to remote data transmission equipment after packaging the data, the remote data transmission equipment used for transmitting a data packet from the data collection equipment to system management equipment, and the system management equipment used for receiving, storing and analyzing sensor network data and controlling and managing the soil humidity sensing equipment. According to a soil humidity sensor network and a dynamic sampling dispatch method thereof, on the premise that the perception precision of the sensor network is not reduced, the sampling frequency of the sensor network can be reduced greatly, and the sensor network is optimized on the basis of application.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a soil moisture sensor network and a sampling scheduling method thereof. Background technique [0002] Precision agriculture is one of the hotspots of agricultural scientific research in the world in recent years. It is the organic combination of existing agricultural production measures and newly developed high-tech. Adjust soil and crop management measures to maximize the optimization of various agricultural inputs to obtain the highest yield and maximum economic benefits; at the same time, protect the agricultural ecological environment and protect agricultural natural resources such as land. At present, precision agriculture is mainly carried out from two aspects, one is precision agriculture based on sensor technology; the other is based on Geographic Information System (GIS), Global Positioning System (GPS), Remote Sensing technology (Remote Sensing) , RS)...
