Title:
DESIGN METHOD FOR GREEN DATA COLLECTION SYSTEM OF HIGH-ENERGY-EFFICIENCY UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/160554
Kind Code:
A1
Abstract:
A design method for a green data collection system of a high-energy-efficiency (EE) unmanned aerial vehicle, relating to the field of data collection and optimization of uplink communications of unmanned aerial vehicles. The method comprises: first constructing a system optimization objective, and an unmanned aerial vehicle periodically receiving data in an uplink communication network of a single unmanned aerial vehicle and ground sensors; then, constructing an optimization problem according to a formula, the optimization objective being to maximize EE ({W}, {t}, {S}); and finally, on the basis of a block coordinate descent method and a successive convex approximation technology, decomposing the original problem into two approximate concave-convex fraction sub-problems, and obtaining a suboptimal solution; and providing an overall iterative algorithm: in each round of iteration, wake-up scheduling S, a time slot t, and an unmanned aerial vehicle trajectory W being alternately optimized by solving for the sub-problems. The solution obtained in each round of iteration is used as an input of the next round of iteration. According to the present invention, a flight trajectory of the unmanned aerial vehicle, the sensor wake-up scheduling, and the flight time slot can be jointly optimized, the transmission information amount and the consumed energy of the sensors are ensured to satisfy the requirements of the system, and the EE of the system is maximized.
