The present invention discloses a UAV traversal route optimization method and system for arable land quality monitoring nodes, wherein the method includes: acquiring the location on the map of wireless sensor network nodes that need to send data to UAVs for arable land quality monitoring Geographical location information; perform geographical location clustering processing on the geographical location information of wireless sensor network nodes on the map to form several geographical location clusters; respectively perform shortest distance traversal and connection of adjacent nodes in several wireless sensor network nodes in geographical location clusters Graph processing, to obtain the traversal connectivity graph; take off the drone to fly and traverse the wireless sensor network nodes according to the traversal connectivity graph, and obtain the monitoring data of the wireless sensor network nodes. In the embodiment of the present invention, after the UAV is used to traverse the cultivated land quality monitoring nodes after the aggregation path is optimized, it can effectively solve the technical problems of improper design of the flight path of the UAV, low aggregation efficiency, and high packet loss rate.
Description
technical field [0001] The present invention relates to the technical field of cultivated land quality detection, in particular to a method and system for optimizing a UAV traversal route of a cultivated land quality monitoring node. Background technique [0002] Cultivated land quality monitoring data is of great significance to agricultural production, ecology, and agricultural product safety; an effective arable land quality monitoring system can be used for the selection of planting varieties, improvement of planting methods, early warning of agricultural land pollution, evaluation of cultivated land quality, and ecological monitoring of agricultural land. and other production and academic research to provide long-term monitoring data; the Ministry of Land and Resources and the Ministry of Agriculture have carried out arable land quality monitoring projects long ago, but the national census data relying on manual sampling has a long cycle, high cost, and few monitoring po...
