A Monitoring System of Ground-Air Interaction Multi-sensory Fusion Plant Growth Condition

Abstract

In view of the shortage of resources and environment in China, the development of intelligent agriculture is relatively backward. The traditional wireless sensor networks (WSNs) use fixed sink node to receive data and communications use multi-hop transmission, which easily creates the problem of “energy hole”. In this paper, a monitoring system of plant growth condition based on ground-air interaction multi-sensory fusion is designed, which embodies modern agriculture. The system uses the unmanned aerial vehicle (UAV) loading mobile sink node to work together with the ground fixed cluster head nodes to achieve single-hop transmission of node communication, and effectively solves the imbalance of energy consumption of each node. In the first two sections, the overall design of the monitoring system is introduced. In sections three and four, the communication methods of the system for mobile sink node are given. In section five, the trajectory planning of UAV mobile sink node is proposed. The sixth section designs the test scheme, collects the related data and analyzes it. The seventh section gives a summary. It is proved that on the basis of the monitoring function of plant growth, the system improves the performance of the traditional static sensor network and achieves the perfect combination of the internet of things and agriculture.
